Show notes - CardioNerds Rounds: Challenging Cases of Cardiovascular Prevention with Dr. Martha Gulati Case #1 Synopsis: A 55-year-old South Asian woman presents to prevention clinic for an evaluation of an elevated LDL-C. Her prior history includes hyperlipidemia, hypertension, obesity, and pre-eclampsia. She was told she had “high cholesterol” a few years prior and would need medication. She started exercising regularly and cut out sweets from her diet. Before clinic, labs showed: Total Cholesterol (mg/dL) of 320, HDL 45, Triglycerides 175, and (directly measured) LCL-C 180. Her Lipoprotein(a) is 90 mg/dL (ULN being ~ 30 mg/dL). Her HbA1C is 5.2% and her 10-year ASCVD Risk (by the Pooled Cohorts Equation) is 5.4%. Her recent CAC score was 110. She prefers not to be on medication and seeks a second opinion. Takeaways from Case #1 As Dr. Gulati notes, in the 2019 ACC/AHA Guideline on the Primary Prevention of Cardiovascular Disease, South Asian ethnicity is considered a “risk enhancing factor.” The pooled cohort equations (PCE) may underestimate risk in South Asians. Furthermore, risk varies within different South Asian populations, with the risk for cardiovascular events seemingly higher in those individuals of Bangladeshi versus Pakistani or Indian origin. There are multiple hypotheses for why this may be the case including cultural aspects, such as diet, physical activity, and tobacco use. A better understanding of these factors could inform targeted preventive measures.In the same 2019 ACC/AHA Guideline on the Primary Prevention of Cardiovascular Disease mentioned above, history of an adverse pregnancy outcome (APO) increases later ASCVD risk (e.g., preeclampsia) and is also included as a “risk-enhancing factor.” Studies have shown that preeclampsia is an independent risk factor for developing early onset coronary artery calcification. Recent data has shown that the risk for developing preeclampsia is not the same across race and ethnicity, with Black women more likely to develop preeclampsia. Black women also had the highest rates of peripartum cardiomyopathy, heart failure, and acute renal failure. After adjustment for socioeconomic factors and co-morbidities, preeclampsia was associated with increased risk of CVD events in all women, the risk was highest among Asian and Pacific Islander women.

CardioNerds (Amit Goyal), Dr. Natalie Stokes (Cardiology Fellow at UPMC and Co-Chair of the Cardionerds Cardio-Ob series), and episode lead Dr. Priya Freaney (Northwestern University cardiology fellow) discuss “The Fourth Trimester” with Dr. Malamo Countouris and Dr. Alisse Hauspurg, from the University of Pittsburgh Departments of Cardiology and Obstetrics and Gynecology, respectively. We discuss the cardiovascular considerations after adverse pregnancy outcomes in the postpartum and long-term follow-up periods. The discussion is focused mainly on hypertensive disorders of pregnancy (HDP), guided by a series of clinical vignettes. We cover a wide range of topics from cardiovascular complications and management considerations in the immediate postpartum period after a HDP, postpartum outpatient follow-up, long term cardiovascular morbidity related to HDP and related preventive strategies, contraceptive considerations for the cardiologist, and interdisciplinary care management pearls for cardiologists working in a cardio-obstetrics team.

Pearls - The Fourth Trimester Blood pressures >160/110 should be treated like a true emergency during pregnancy and the postpartum period, as the cerebrovascular circulation is more sensitive to hypertension, due to hormonal changes related to pregnancy.Women with pre-eclampsia are at higher risk for peripartum cardiomyopathy. Have a low threshold to do a clinical heart failure evaluation (i.e., natriuretic peptides, echocardiogram), and administer diuretics as appropriate to improve volume status and blood pressure.Women with HDP should have their blood pressures monitored closely after discharge, ideally with a home BP monitoring program, as they can have exacerbations of their HTN for up to 2 weeks postpartum.The American Rescue Plan Act of 2021 included a landmark policy to extend postpartum Medicaid coverage up to a year postpartum (from 60 days).Remember to take a reproductive history for every woman you see in cardiology clinic! This can be done in one minute. At a minimum, include obstetric history [number of pregnancies, outcome of each pregnancy, gestational age and weight at delivery, pregnancy complications (HDP, GDM, etc), and delivery method] and menopausal history (age at menarche, age at menopause).The Pooled Cohort Equations may underestimate ASCVD risk for a woman who has had pregnancy complications or premature menopause – consider obtaining a CAC score to aid in risk-stratification in middle-aged women who may have underestimated risk.Low dose aspirin during pregnancy in women who have risk factors for pre-eclampsia reduces the risk of development of HDP by 15-20%. Quotables - The Fourth Trimester “Some of our traditional approaches to caring for women in the postpartum period just aren’t realistic…we need to think about how we can improve care from a policy standpoint to ensure women have access to care and think about how we deliver care.” – Dr. Alisse Hauspurg “Silos are never good. Cardio-obstetrics is a space where you really want to have open communications, be truly collaborative – taking into consideration the expertise of multiple disciplines…because it’s really hard to do it alone.” – Dr. Malamo Countouris Show notes - The Fourth Trimester For more on hypertensive disorders of pregnancy enjoy: Episode #128: Cardio-Obstetrics: Hypertensive Disorders of Pregnancy with Dr. Jennifer LeweyEpisode #66: Case Report: Severe Pre-eclampsia & Cardio-Obstetrics – UPMC Hypertensive Disorders of Pregnancy 1.     What are some of the immediate postpartum cardiovascular risks and complications following a hypertensive disorder of pregnancy (H...

Case Summary - Dyspnea with an LVAD: A Tale of Hypoxia and Hemodynamics A 53-year-old man with an LVAD placed 3 months prior presents with progressive dyspnea since LVAD implant, though it has acutely worsened over the past 2 weeks. Two weeks ago, he had a hemodynamic and echocardiographic ramp study, where the LVAD speed was increased. By increasing the speed, his LV was more adequately decongested, and flow improved. In the Emergency Department, he was hypoxic on room air, and remained so with escalation ultimately with intubation. Even then he remained severely hypoxic requiring cannulation to veno-venous ECMO. Chest imaging was normal, and LVAD parameters were normal without any alarms. An astute clinician noticed that when the patient became hypertensive, his oxygen saturation improved. A subsequent echocardiogram revealed a patent foramen ovale, with right to left shunting. The patient then went to the cath lab, where simultaneous right atrial and left atrial pressures and oxygen pressures were measured, along with trans-esophageal echocardiography, while adjusting LVAD speed. It became evident that right-to-left shunting occurred only when there was high LVAD speed and low peripheral blood pressure. Essentially, faster LVAD speeds (sucking blood from the LV) and low systemic blood pressure (reducing LV afterload) increased right to left shunting by decreasing the left atrial pressure relative to the right atrial pressure. The PFO was closed at that time, drastically improving oxygenation. He was decannulated and extubated the following day. Invasive Hemodynamic Study Unmasks Intracardiac Shunt With Ventricular Assist Device | Circulation: Heart Failure (ahajournals.org) Episode Teaching -Dyspnea with an LVAD: A Tale of Hypoxia and Hemodynamics Pearls PFOs are present in up to 25% of individuals, including those with LVADs.LV unloading, and therefore LA decompression, depends on both LVAD speed and systemic vascular resistance.Blood pressure dependent hypoxia may be suggestive of a right-to-left intracardiac shunt.Hypoxia refractory to mechanical ventilation should raise suspicion for intracardiac shunt.Patients with LVADs can suffer from the same diseases that anyone can. Notes - Dyspnea with an LVAD: A Tale of Hypoxia and Hemodynamics 1. What factors influence LVAD flow? Factors that influence LVAD flow include pump speed, blood pressure, volume status, RV function, cardiac rhythm, and some other variables. The faster the pump is spinning, the more flow you should provide (to an extent). However, if your LV is underfilled, either from systemic hypovolemia or an RV not providing the needed LV preload, then you have no blood to flow! If you have high systemic vascular resistance, then you will have less forward flow,

CardioNerds, Daniel Ambinder and CardioNerds Academy Program Director, Dr. Tommy Das (Cardiology fellow, Cleveland Clinic), Dr. Jacqueline Latina (Structural heart fellow, Johns Hopkins) discuss aortic stenosis and the story of TAVR from both the historical perspective and in terms of future directions with Dr. Jon Resar, Professor of Medicine and Director of the Adult Catheterization Laboratory and Interventional Cardiology at the Johns Hopkins Hospital. This episode is brought to you for Heart Valve Disease Awareness Day. Audio editing by CardioNerds Academy Intern, Shivani Reddy. As many as 11 million Americans have heart valve disease (HVD)—a potentially disabling and deadly disease—yet 3 out of 4 Americans know little to nothing about heart valve disease.

Pearls and Quotes - Aortic Stenosis and the Story of TAVR In the previous century, patients with severe aortic stenosis who were treated “medically” had 50% mortality over 2 years after developing symptoms. Balloon aortic valvuloplasty was initially touted as extremely “efficacious” for aortic stenosis but follow-up studies showed that the improvement in symptoms were not durable, and long-term prognosis was dismal. The PARTNER Trial started enrolling in 2007 in extreme risk patients – patients who were not surgical candidates. In 2010, the PARTNER trial was published and TAVR blew away the “standard of care” in inoperable patients at the time, cutting outcomes in half (composite of death and repeat hospitalization). The PARTNER trial studied balloon expandable intra-annular valve implantation. The CoreValve trial studied self-expanding supra-annular valve implantation and was published in 2014. The “Heart Team” approach entails collaborative decision making between cardiologists and cardiac surgeons to personalize management for patients. Both intra-annular and supra-annular valves show non-inferior outcomes to surgery in intermediate and low risk patients. Revascularization prior to TAVR is an evolving arena; the trend has been interventionalists performing fewer PCIs prior to TAVR given the benefit is not clear if angina is not a prominent symptom. Show notes - Aortic Stenosis and the Story of TAVR (TAVR/TAVI are using interchangeably) CardioNerds Aortic Stenosis, updated 1.20.21 1. In the 1990s, patients with severe aortic stenosis (AS) who were deemed to be at high surgical risk would weigh the risks of surgery and prolonged recovery. Balloon Aortic Valvuloplasty (BAV) was first performed by Dr. Alain Cribier in 1986. The technique was based on the foundation of pulmonary valvuloplasty performed initially in 1982 by Drs. Jean Kan and Bob White, and mitral valvuloplasty in 1984. BAV was initially touted as an efficacious cure for aortic stenosis, but unfortunately it had a high restenosis rate as well as high risks for stroke and vascular complications (no closure devices at that time) with an overall poor long-term prognosis. Balloon aortic valvuloplasty was primarily used for decompensated Class IV heart failure in non-surgical candidates. 2. Transcatheter aortic valve replacement (TAVR/TAVI) was developed and first performed in human in 2002.(1) This was performed by Dr. Alain Cribier in France in 2002, initially by trans-septal approach and then by retroaortic approach. Here is a representative diagram of the procedure. Figure: Transcatheter Aortic-Valve Replacement. The transcatheter valve is positioned at the level of the native aortic valve during the final step of valve replacement, when the balloon is inflated within the native valve during a brief period of rapid ven...

The President of the New York ACC Chapter Dr. Hima Vidula discusses D&I initiatives at her chapter. Episode introduction and audio editing by CardioNerds Academy Intern, Shivani Reddy. Although women compose 50% of medical students in the United States, cardiology remains a male dominated field. Gender disparity is even more prominent when we look at leadership positions. In this episode we discuss why and how cardiology (and advanced heart failure) can be such a rewarding field for women. The episode reflects on the significant contributions women have made to the field in the past and how they continue to move the field with respect to clinical care and research. The PA-ACC & CardioNerds Narratives in Cardiology is a multimedia educational series jointly developed by the Pennsylvania Chapter ACC, the ACC Fellows in Training Section, and the CardioNerds Platform with the goal to promote diversity, equity, and inclusion in cardiology. In this series, we host inspiring faculty and fellows from various ACC chapters to discuss their areas of expertise and their individual narratives.

Audio editing by CardioNerds Academy Intern, Christian Faaborg-Andersen. In the recent years, purified omega 3 fatty acids and its esters have emerged as a potential new tool in our arsenal for management of hypertriglyceridemia and atherosclerotic coronary artery disease. In this episode we review the sources and basic structure of these compounds, as well as their metabolic effects as it pertains to cardiovascular disease. Using hypothetical patient cases, we also discuss scenarios in which these therapies can be useful.

Pearls Omega 3 (n-3) fatty acids are a class of polyunsaturated fatty acids [PUFA]. The most studied n-3 fatty acids include eicosapentaenoic acid [EPA], docosahexaenoic acid [DHA] and alpha linoleic acid [ALA]. ALA is found in certain vegetable oils while EPA and DHA are abundant in fish sources.Cardiovascular benefits of n-3 fatty acids include blood pressure reduction, enhanced diastolic function, triglyceride reduction, and immunomodulatory properties.Inflammation plays a major role in the atherogenic process and plaque rupture. Inflammatory marker hs-CRP is a risk enhancing factor for predicting future ASCVD risk. Ongoing trials are investigating therapy that target the inflammatory process in treatment of atherosclerotic heart disease.Prevention and management of ASCVD require aggressive lifestyle modifications and medical therapy addressing risk factors and underlying inflammatory conditions.Purified forms of n-3 fatty acids are approved for the treatment of severe hypertriglyceridemia and as an adjunct therapy to statins for reduction of coronary events in high-risk individuals. Show notes 1. What are omega 3 (n-3) fatty acids? What are the natural sources of n-3 fatty acids? n-3 fatty acids are class of polyunsaturated fatty acids [PUFA]. PUFA are types of unsaturated fats that have more than one double bond in their backbone. PUFAs are important constituents of the phospholipids of all cell membranes.The most studied n-3 fatty acids include eicosapentaenoic acid [EPA], docosahexaenoic acid [DHA] and alpha linoleic acid [ALA].ALA is found in certain vegetable oils including walnuts, flaxseeds, chia seeds. EPA and DHA are abundant in cold water fish oils such as salmon, mackerel, tuna sardines. Interestingly, farm raised fish usually have higher levels of EPA and DHA than wild caught fish; however, this depends on what the fish are fed. Another important class of PUFAs are omega 6 (n-6) fatty acids, found in vegetable oils (1,2).  2. What are the metabolic effects of omega 3 fatty acids? Multiple early studies have demonstrated the anti-inflammatory properties of n-3 fatty acids.The typical Western diet with a high arachidonic acid (an n-6 fatty acid) content promotes atherogenesis leading to the high incidence of CAD in this population.

They discuss a case of a 52-year-old woman with limited cutaneous systemic sclerosis who presents with progressive symptoms of heart failure and is found to have a severe, non-ischemic cardiomyopathy. The etiology of her cardiomyopathy is not clear until her untimely death. She is ultimately diagnosed with cardiac AL amyloidosis with isolated vascular involvement a real occam’s razor or hickam’s dictum conundrum. We discuss the work-up and management of her condition including a detailed discussion of the differential diagnosis, the underlying features of systemic sclerosis with cardiac involvement as well as cardiac amyloidosis, the role of a shock team in managing cardiogenic shock, and how to identify those with advanced or stage D heart failure.

Case Summary - Occam’s Razor or Hickam’s Dictum? This is a case of a 52-year-old woman with limited cutaneous systemic sclerosis who presented with progressive dyspnea on exertion and weight loss over the course of 1 year. Her initial work-up was notable for abnormal PFTs and finding of interstitial pneumonia on high-resolution CT, an ECG with frequent PVCs and normal voltage, a transthoracic echocardiogram with a mildly reduced ejection fraction of 40%, and a right/left heart catheterization with normal coronary arteries, filling pressures, and cardiac output. Scleroderma-related cardiac involvement is suspected. She is placed on GDMT, but her condition worsens over the next several months, and repeat echocardiogram shows severely reduced biventricular function, reduced LV global longitudinal strain (GLS) with apical preservation of strain, severely reduced mitral annular tissue Doppler velocities, and a normal left ventricular wall thickness. Scleroderma-related cardiac involvement remains highest on the differential, but because of some findings on the echo that are concerning for cardiac amyloidosis, an endomyocardial biopsy was obtained. It showed vascular amyloid deposition without interstitial involvement. The diagnosis of cardiac amyloid was discussed but deemed unlikely due to lack of interstitial involvement. However, a serologic work-up soon revealed a monoclonal serum lambda light chain and a follow-up bone marrow biopsy showed 20% plasma cells. She was discharged with very near-term follow-up in oncology clinic with a presumptive diagnosis of AL amyloidosis, but she unfortunately returned in shock and suffered a cardiac arrest. She initially survived and underwent emergent veno-arterial extracorporeal membrane oxygenation (VA ECMO) cannulation with subsequent left ventricular assist device placement (LVAD). However, she passed away due to post-operative hemorrhage. Autopsy was consistent with a final diagnosis of cardiac AL amyloidosis with isolated vascular involvement.  Case Media - Occam’s Razor or Hickam’s Dictum?

Approximately 350,000 adults per year in the US experienced out-of-hospital cardiac arrest (OHCA). Only about 10% of such patients survive their initial hospitalization. The key drivers of successful resuscitation from OHCA are bystander cardiopulmonary resuscitation (CPR) and public use of an automated external defibrillator (AED). Survival rates from OHCA vary dramatically between US regions. For instance, the extracorporeal CPR (eCPR) program at the University of Minnesota has over a 40% survival rate in patients with OHCA and refractory ventricular fibrillation (VF) based on data published in the ARREST trial. In this episode, we are joined by experts from the University of Minnesota, including Dr. Jason Bartos (Interventional and Critical Care Faculty) and Dr. Julie Power (Chief Fellow at University of Minnesota and CardioNerds Academy Fellow), along with Dr. Yoav Karpenshif (Co-Chair Critical Care Series, University of Pennsylvania) and CardioNerds Co-Founders (Amit Goyal and Dan Ambinder) to discuss cardiac arrest, E-CPR, & post-arrest care.

The three main hemodynamic issues that need to be addressed in any form are unbalanced flow, pulmonary over-circulation, and blood mixing.  The Fontan palliation is a series of operations for congenital heart disease patients in whom biventricular repair is not feasible.  In the completed Fontan circulation, systemic venous blood is surgically routed directly to the lungs, effectively bypassing the heart, and creating passive pulmonary blood flow.  The hallmarks of the Fontan circulation (and Fontan failure) are elevated central venous pressure and low cardiac output.  Patients with Fontan circulation may experience significant morbidity in the long term from both cardiac and non-cardiac sequelae, and require lifelong specialist care.  Show notes 1. Why do some patients require Fontan palliation?  Many different types of anatomies may ultimately require single ventricular palliation via the Fontan procedure due to inadequate biventricular function to support both pulmonary and systemic circulations. Some examples include Tricuspid Atresia (hypoplastic RV), Double Inlet Left Ventricle (DILV; hypoplastic RV), Hypoplastic Left Heart Syndrome (HLHS; hypoplastic LV), and atrioventricular septal defects (AVSD; either RV or LV may be inadequate based on “commitment” of the common AV valve). The Fontan procedure was first described in 1971; at this time, mortality of single ventricular patients exceeded 90% in the first year of life.  2. What are the stages of Fontan palliation?  Effective pulmonary blood flow/balancing flow to the pulmonary and systemic circulations: for many conditions, this involves retrograde pulmonary blood flow from a systemic -> PA shunt (i.e. Blalock-Taussig-Thomas “BTT” shunt in which the subclavian artery is turned down and anastomosed to the pulmonary artery). In infants, the pulmonary vascular resistance (PVR) is high perinatally and gradually lowers over the first 3 months of life to adult levels with exposure to the atmosphere’s natural pulmonary vasodilator: oxygen. Thus, in the first 3 months of life babies have an intri...
