Show notes - Challenging Cases - Atrial Fibrillation with Dr. Hugh Calkins Case #1 Synopsis: A woman in her mid-60s presents with symptomatic paroxysmal atrial fibrillation (AF). An echocardiogram has demonstrated that she has a structurally normal heart. Her primary care doctor had started Metoprolol 50 mg twice a day but she has remained symptomatic. In office, an EKG confirms AF, but she converts to sinus while there. She is seeking advice to prevent further episodes and in general wants to avoid additional medications Case #2 Takeaways We discussed several potential options for treatment. Amongst the first things we discussed was amiodarone. In a patient of this nature without structural heart disease and under the age of 70, Dr. Calkins discussed that he would probably consider amiodarone as a 2nd line option. While amiodarone may be effective in maintaining sinus rhythm in comparison to other antiarrhythmic medications like sotalol, flecainide, and propafenone, it does have significant toxicity.If antiarrhythmic drugs (AAD) were to be considered, we also discussed the options of dofetilide versus sotalol. Dofetilide typically requires inpatient initiation due to the risk of QT prolongation and Torsades. Since women tend to have longer corrected QT (QTc) intervals, high dose dofetilide may be more proarrhythmogenic in women. Though, Dr. Calkins noted that many patients don’t tolerate sotalol due to fatigue and generally dofetilide is well tolerated.When it comes to the “pill in the pocket” approach, Dr. Calkins noted that its utility is more so in patients with persistent AF that is known to not stop on its own. For instance, an individual who has AF a few times a year that is persistent may benefit from flecainide or propafenone (“in the pocket”) instead of being brought in for an electrical cardioversion. In this scenario, the first time one of these agents is used, the patient ought to be closely monitored. For our patient, her episodes were too frequent and self-terminating for a “pill in the pocket” approach to be effective.Current guideline recommendations for catheter ablation include a Class IA recommendation for patients with paroxysmal AF refractory to AADs, and a Class IIA recommendation as first-line therapy for patients with paroxysmal AF.In the 2020 ESC Atrial Fibrillation Guidelines, catheter ablation is given a Class IA recommendation to improve symptoms of AF recurrences in patients who have failed or are intolerant of one Class I or III AADs. For patients who have failed or have been intolerant of beta blocker alone for rhythm control,

It’s not about being male or female or pregnant or not pregnant, it’s about what you love to do and how can you master it.” “Our careers can wait, but family planning cannot. If you are fortunate enough to have the opportunity to start a family even if it’s during your training, you should”. Notes - Radiation Safety & Women in Interventional Cardiology with Dr. Sheila Sahni What are procedural techniques to utilize during a heart catheterization to reduce radiation exposure to the operator? Decrease number and length of cine acquisitions and fluoroscopy timeDecrease the frame rate - halving the frame rate reduces radiation dose by 50%Decrease the distance between the image intensifier and the patientLimit steep LAO angulationsApply collimation as much as possible which reduces overall patient dose and scatter radiationLimit digital magnification which can increase skin dose exposure by 50% What are the important dose limits to consider for a pregnant female and her fetus in the cath lab? The US Nuclear Regulatory Commission (NRC) regulatory equivalent dose limit is 5mSv during the entire pregnancy of the declared pregnant woman.The annual natural background radiation dose in the US is 3mSv.The average under-lead dose to a working pregnant interventionalist over the entire gestation is ~0.3mSv.The fetus of a working pregnant interventionalist is estimated to ...

The modern CICU has evolved to include patients with complex pulmonary mechanics requiring more non-invasive and mechanical ventilation. Series co-chairs Dr. Eunice Dugan and Dr. Karan Desai along with CardioNerds Co-founder Dr. Amit Goyal were joined by FIT lead, Dr. Sam Brusca, who has completed his NIH Critical Care and UCSF Cardiology fellow and currently faculty at USCF. We were fortunate enough to have two expert discussants: Dr. Burton Lee, Head of Medical Education and Global Critical Care within the National Institutes of Health Critical Care Medicine Department and master clinician educator with the ATS Scholar’s Critical Care for Non-Intensivists program, and Dr. Chris Barnett, ACC Critical Care Cardiology council member and Section Chair of Critical Care Cardiology at UCSF.  In this episode, these experts discuss the basics of mechanical ventilation, including the physiology/pathophysiology of negative and positive pressure breathing, a review of ventilator modes, and a framework for outlining the goals of mechanical ventilation. They proceed to apply these principles to patients in the CICU, specifically focusing on patients with RV predominant failure due to pulmonary hypertension and patients with LV predominant failure.

Pearls and Quotes - Positive Pressure Ventilation in the CICU Respiratory distress, during spontaneous negative pressure breathing can lead to high transpulmonary pressures and potentially large tidal volumes. This will increase both RV afterload (by increasing pulmonary vascular resistance) and LV afterload (by increasing LV wall stress). An analogy for the impact of negative pleural pressure during spontaneous respiration on LV function is that of a person jumping over a hurdle. The height of the hurdle does not increase, but the ground starts to sink, so it is still harder to jump over. Intubation in patients with right ventricular failure is a tenuous situation, especially in patients with chronic RV failure and remodeling (increased RV thickness, perfusion predominantly during diastole, RV pressure near or higher than systemic pressure). The key tenant to safe intubation is avoiding hypotension, utilizing induction agents such as ketamine or etomidate, infusing pressors, and potentially even performing awake intubations. Non-invasive positive pressure ventilation in HFrEF has hemodynamic effects similar to a cocktail of IV inotropes, dilators, and diuretics. CPAP decreases pulmonary capillary wedge pressure (LV preload), decreases systemic vascular resistance (afterload), and increases cardiac output. Airway pressure during mechanical ventilation is based on the “equation of motion”: Pressure = Volume/Compliance + Flow*Resistance + PEEP. Our goals of oxygenation on mechanical ventilation include achieving acceptable PaO2/Sat with the lowest FiO2 possible (avoiding oxygen toxicity) and optimal PEEP (which increases oxygenation but can have detrimental impact on cardiac output) Our goals of ventilation on mechanical ventilation include achieving acceptable pH and PaCO2 while preventing ventilator induced lung injury and avoiding auto-PEEP. We prevent lung injury by reducing tidal volume (ideally <8cc/kg, plateau pressure < 30 cmH20, driving pressure < 15 cmH20) and auto-peep by reducing respiratory rate (and allowin...

CardioNerds (Amit and Dan) join join Dr. Andrew Dicks (Vascular medicine physician at Prisma Health, former fellow at Mass General Vascular) and Dr. Prateek Sharma (Vascular interventional & medicine fellow at MGH) for an ice-cold drinks at the Esplanade in Boston, MA to discuss a case about a patient who developed a pulmonary embolism and masterfully discuss the diagnosis and management of of pulmonary emboli. Dr. Ido Weinberg (Director, Vascular Medicine Fellowship at MGH) provides the ECPR for this episode. Case Abstract: A 59-year-old Spanish-speaking man with no significant past medical history presents after falling 15-20 feet from a ladder and landing on his back. He was found to have an L1 fracture and left radial fracture and underwent T12-L2 fusion with neurosurgery on hospital day 1 and ORIF of left radial fracture with orthopedic surgery on hospital day 2. On hospital day 5, he develops acute onset tachycardia with HR in the 130s bpm with new O2 requirement associated with mild shortness of breath at rest without any chest discomfort. His labs were notable for an elevated troponin and proBNP. He underwent CTPA which demonstrated acute bilateral occlusive pulmonary emboli (PE) extending in the right and left main pulmonary arteries. TTE demonstrated right ventricle dilation. The patient was started on a heparin infusion and a PE response team (PERT) meeting was held to discuss treatment options. Given recent surgery, use of thrombolytic therapy was felt to be too risky and thus he was taken for percutaneous thrombectomy in the cath lab. PA pressure prior to intervention was 51/21 mmHg. The patient underwent suction thromboembelectomy with the Flow Triever device with extraction of thrombus and improvement in PA pressure to 19/11 mmHg. He was treated with anticoagulation thereafter and discharged home two days after the procedure.

Case Media Acute bilateral occlusive and nonocclusive pulmonary emboli extending from the right and left main pulmonary arteries to the lobar and segmental arteries of all the lobes.  Moderate right heart strain including the right atrium and the right ventricle. RV/LV ratio > 1.0. Right ventricular cavity is dilated (RV size at the base measures to 45mm). Right ventricular systolic function is moderately decreased. Right ventricular free wall is hypokinetic with sparing of the right ventricular apex consistent with acute right ventricular strain Pulmonary angiography demonstrated extensive proximal bilateral PEs Caption: Post-procedure TTE demonstrated resolution of RV strain with normalization of RV size and function. Episode Schematics & Teaching Pearls While there are markers to suggest PE, such as ECG findings or evidence of RV dilatation, a PE cannot be confirmed without imaging.Elevation of cardiac biomarkers and evidence of RV dysfunction are used to risk stratify PE, not the degree of thrombus burden or locale of thrombus.Enoxaparin is the preferred anticoagulant to initiate at time of PE diagnosis if comorbidities allow.Optimal treatment of intermediate risk PE remains uncertain as there is little data about long-term outcomes. Aggressive treatment should be used judiciously and chosen on a case-by-case basis.PE response teams (PERT) allow for multidisciplinary expert opinion in the face of scarce evidence to determine what is felt to be the best management strategy. Notes 1. What is a PERT team and why is it helpful? We have several tools and approaches for the management of PE. There are also many subspecialities involved in the care of patients with PE, including vascular medicine,

CardioNerds (Daniel Ambinder) and ACHD series co-chair Dr. Dan Clark discuss advanced heart failure therapies including mechanical circulatory support (MCS) and heart transplantation (HT) in patients with adult congenital heart disease (ACHD) with Dr. Rafael Alonso-Gonzalez, cardiologist and director of Adult Congenital Heart Disease program at the University of Toronto and ACHD fellow Dr. Andy Pistner (University of Washington). They cover epidemiology of heart failure in ACHD, outcomes after HT, unique challenges of HT in this population, impact of allocation policies on access to transplantation, and regionalization of advanced heart failure care. They also discuss a practical approach to advanced heart failure therapy evaluation in ACHD. Audio editing by CardioNerds Academy Intern, student doctor Adriana Mares. The CardioNerds Adult Congenital Heart Disease (ACHD) series provides a comprehensive curriculum to dive deep into the labyrinthine world of congenital heart disease with the aim of empowering every CardioNerd to help improve the lives of people living with congenital heart disease.

Pearls - Advanced Heart Failure Therapies (MCS/HT) Among ACHD Patients Heart failure is a major comorbidity and the leading cause of death in adults with congenital heart disease.Identification of advanced heart failure in ACHD is challenging. ACHD patients do not always self-identify exercise limitations or exertional dyspnea. Cardiopulmonary exercise testing is a useful tool in evaluating these patients.Patients with ACHD awaiting heart transplantation are less likely than non-ACHD patients to receive a heart transplant, and ACHD patients have an increased risk of death or delisting while awaiting heart transplantation.Evaluation of transplant candidacy and potential need for multi-organ transplantation in complex congenital heart disease (i.e., Fontan palliation) requires a multidisciplinary approach.Regionalization of care improves outcomes for ACHD patients with advanced heart failure. High volume transplant centers have better early survival for ACHD patients after heart transplant, and the highest volume ACHD transplant centers in each UNOS region have better early survival. Show notes - Advanced Heart Failure Therapies (MCS/HT) Among ACHD Patients 1. How many ACHD patients have heart failure? Patients with ACHD are a large and heterogeneous group. The signs and symptoms of heart failure vary widely depending on the underlying congenital heart disease. Patients with D-transposition of the great arteries repaired with an arterial switch operation have low rates of heart failure (~3%)1 compared to those patients Fontan palliation for single ventricle physiology (40%)2. Heart failure is the leading cause of death in patients with ACHD3,4. 2. How many patients with ACHD end up receiving a heart transplant or mechanical circulatory support? Heart transplantation for congenital heart disease in adults has been increasing in frequency since the late 1980s. Between 2010 and 2012, this accounted for 4% of all adult heart transplants in the United States5. This represents a small fraction compared to the number of adults who die due to complications of heart failure ...

CardioNerds (Amit Goyal), Dr. Colin Blumenthal (CardioNerds Academy House Faculty Leader and FIT at the University of Pennsylvania), and Dr. Anjali Wagle (CardioNerds Ambassador and FIT at Johns Hopkins University), discuss the baseline assessment of stroke and bleeding risk in patients with atrial fibrillation (AF) with Dr. Elaine Hylek. Dr. Hylek is a professor of medicine at the Boston University School of Medicine and is the Director of the Thrombosis and Anticoagulation Service at Boston Medical Center. Stroke is a potentially devastating and preventable complication of AF. Understanding the balance between stroke and bleeding risk is crucial in determining who should be on anticoagulation. Join us to discuss this topic! In the next episode of the series, we will discuss situational risk assessment in the context of peri-cardioversion, peri-procedural status, triggered atrial fibrillation, and more.

Pearls and Quotes - Atrial Fibrillation: Assessment of Stroke & Bleeding Risk The CHA2DS2-VASc should be used to determine stroke risk in all patients. It was updated from the CHADS2 score to better separate patients into high and low risk and a score of 0 has a very low risk of a stroke. Understanding a given model’s derivation is key to application for any risk model. Understanding who was and was not included when a risk score was derived helps determine how to clinically use it. For example, mechanical valves, hypertrophic cardiomyopathy, cardiac amyloidosis, and moderate to severe MS were all excluded or poorly represented and should receive AC in AF regardless of CV. The HAS-BLED score should be used to identify modifiable risk factors for bleeding and address them. It is less useful to determine when we should stop AC. Factors that go into the score are dynamic and the intention was to alert the provider of potentially modifiable factors that could be addressed to lower bleeding risk (such as better BP control). Fear the clot. Patients should be on AC unless there is a serious contraindication as embolic strokes can be devastating with a high mortality (~24% mortality at 30 days) “What am I saying by not writing the prescription... I am saying that it’s OK to have an ischemic stroke.” Survey data shows that patients are willing to experience 3.5 GI bleeds on average before 1 stroke, so favoring AC is often a patient centered approach Notes - Atrial Fibrillation: Assessment of Stroke & Bleeding Risk Notes drafted by Dr. Anjali Wagle 1. Why do strokes happen in atrial fibrillation? Why is reducing stroke risk so important? Atrial fibrillation is associated with a significantly increased risk of stroke. The mortality of strokes related to AF have been estimated to be around 25% at 30 days in early studies which included either persistent or permanent AF, though of note, these studied were biased towards larger strokes since the diagnosis was based on physical exam and not high resolution imaging.

With the advent and rapid evolution of contemporary percutaneous coronary intervention (PCI), the early invasive management of acute myocardial infarction (AMI) has become a mainstay in therapy with significant impact on patient outcomes. However, despite modern advances in technology and system-based practices, AMI presenting with cardiogenic shock (CS) continues to portend a high risk of morbidity and mortality. Few randomized controlled clinical trials are available to guide decision-making in this uniquely challenging patient population. Understanding the pathophysiologic mechanism by which injury occurs and propagates the shock cycle can be instrumental in selecting an appropriate strategy for revascularization and left ventricular unloading. In this episode we are joined by Dr. Venu Menon, The Mehdi Razavi Endowed Chair and Professor of Medicine at the Cleveland Clinic Lerner College of Medicine,  section head of clinical cardiology, fellowship program director, and director of the Cardiac intensive care unit at the Cleveland Clinic. Dr. Menon shares his wealth of knowledge and experience to help us review the contemporary data available for AMI CS management in a case-based discussion. We are also joined by Dr. Priya Kothapalli, star chief fellow and future interventionalist from University of Texas at Austin, series co-chair Dr. Yoav Karpenshif, and CardioNerds Co-founders Amit Goyal and Daniel Ambinder.

Pearls and Quotes - Approach to Acute Myocardial Infarction Cardiogenic Shock with Dr. Venu Menon The H&P does matter! Age, location of infarction, heart rate, systolic blood pressure, and heart failure symptoms all carry weight in determining prognosis and risk of mortality.Define functional status, comorbid conditions, and life expectancy to help guide clinical decision-making. Do a quick bedside echocardiogram if possible to elucidate the predominant mechanism driving CS and rule out mechanical complications.Act with urgency! Get to the catheterization lab to characterize coronary anatomy and revascularize the culprit vessel as soon as possible.Minimize/avoid the use of vasopressors; if needed, wean as quickly as possible to avoid worsening myocardial ischemia. Consider mechanical circulatory support early!Despite dramatic advances in AMI management, data is limited in AMI CS management. Ask the important questions, get involved in the scientific inquiry as a trainee! Show notes - Approach to Acute Myocardial Infarction Cardiogenic Shock with Dr. Venu Menon 1. Why is it important to recognize AMI complicated by CS? AMI CS occurs in 7-10% of patients presenting with AMI and has a higher prevalence among elderly patients.The SHOCK trial (1999) showed significant survival benefit at 6 months with early revascularization with balloon angioplasty compared to medical therapy alone in AMI CS.Registry data suggests that early revascularization is beneficial in AMI CS even in elderly patients. Decision-making should be guided using a holistic view of the patient’s overall biology.Despite advances in revascularization techniques and availability of mechanical support, AMI CS portends a 40-45% risk of 30-day mortality in the modern era.Significant variation in management strategy exists between centers and data to guide decision-making is li...

It’s another session of CardioNerds Rounds! In these rounds, Co-Chair, Dr. Karan Desai (previous FIT at the University of Maryland Medical Center, and now faculty at Johns Hopkins) joins Dr. Ryan Tedford (Professor of Medicine and Chief of Heart Failure and Medical Directory of Cardiac Transplantation at the Medical University of South Carolina in Charleston, SC) to discuss the nuances of managing pulmonary hypertension in the setting of left-sided heart disease. Dr. Tedford is an internationally-recognized clinical researcher, educator, clinician and mentor, with research focuses that include the hemodynamic assessment of the right ventricle and its interaction with the pulmonary circulation and left heart.

Show notes - Challenging Cases - Nuances in Pulmonary Hypertension Management with Dr. Ryan Tedford Case #1 Synopsis: A woman in her late 30s presented to the hospital with 4 weeks of worsening dyspnea. Her history includes dilated non-ischemic cardiomyopathy diagnosed in the setting of a VT arrest around 10 years prior. Over the past 10 years she has been on guideline-directed medical therapy with symptoms that had been relatively controlled (characterized as NYHA Class II), but without objective improvement in her LV dimensions or ejection fraction (LVEF 15-20% by TTE and CMR and LVIDd at 6.8 cm). Over the past few months she had been noting decreased exercise tolerance, worsening orthopnea, and episodes of symptomatic hypotension at home. When she arrived to the hospital, she presented with BP 95/70 mmHg, increased respiratory effort, congestion and an overall profile consistent with SCAI Stage C-HF shock. In the case, we go through the hemodynamics at various points during her hospitalization and discuss options for management including medical therapy and mechanical support. The patient was eventually bridged to transplant with an Impella 5.5. Initial Hemodynamics Right Atrium (RA) Pressure Tracing: Right Ventricle (RV) Pressure Tracing: Pulmonary Artery (PA) Pressure Tracing: Pulmonary Capillary Wedge Pressure (PCWP) Tracing: Case 1 Rounding Pearls One of the first points that Dr. Tedford made was thinking about our classic frameworks of characterizing acute decompensated heart failure, specifically the “Stevenson” classification developed by Dr. Lynne Stevenson that phenotypes patients along two axes: congestion (wet or dry) and perfusion (warm or cold). Dr. Tedford cautioned that young patients may not fit into these classic boxes well, and that a normal lactate should not re-assure the clinician that perfusion is normal.In reviewing the waveforms, Dr. Tedford took a moment to note that besides just recording the absolute values of the pressures transduced in each chamber or vessel, it is critical to understand the morphology of the tracings themselves. For instance, with the RA pressure tracing above, there is no respiratory variation in the mean pressure. This is essentially a “resting Kussmaul’s sign,” which is typically indicative of significant RV dysfunction. Thus, even though our echocardiogram in this case did not necessarily show a significantly dilated RV with mildly reduced longitudinal function (T...
