What Makes Your Heart Flutter About Dokanjal Heart Disease?

Congenital heart disease is the most common birth defect, affecting 1 in 100 babies. Amongst these ventricular septal defects are very common with the majority of patients living into adulthood. In this episode we will be reviewing key features of VSDs including embryologic origin, anatomy, physiology, hemodynamic consequences, clinical presentation and management of VSDs. Dr. Tommy Das (CardioNerds Academy Program Director and FIT at Cleveland Clinic), Dr. Agnes Koczo (CardioNerds ACHD Series Co-Chair and FIT at UPMC), and Dr. Anu Dodeja (Associate Director for ACHD at Connecticut Children’s) discuss VSDs with expert faculty Dr. Keri Shafer. Dr. Shafer is an adult congenital heart disease specialist at Boston Children’s Hospital, and an assistant professor of pediatrics within Harvard Medical School. She is a medical educator and was an invited speaker for the inaugural CardioNerds Sanjay V Desai Lecture, on the topic of growth mindset. Script and notes were developed by Dr. Anu Dodeja. Audio editing by CardioNerds Academy Intern, Shivani Reddy. 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. This series is multi-institutional collaborative project made possible by contributions of stellar fellow leads and expert faculty from several programs, led by series co-chairs, Dr. Josh Saef, Dr. Agnes Koczo, and Dr. Dan Clark. The CardioNerds Adult Congenital Heart Disease Series is developed in collaboration with the Adult Congenital Heart Association, The CHiP Network, and Heart University.

Pearls - Ventricular Septal Defects Most common VSDs: Perimembranous VSD The shunt volume in a VSD is determined largely by the size of the defect and the pulmonary vascular resistance. VSDs cause left to right shunt. The long-term effects are left sided chamber dilation, as is the case with PDAs (post-tricuspid shunts) VSDs can be associated with acquired RVOTO, double chamber right ventricle, LVOTO/sub aortic membrane formation, and aortic regurgitation from aortic valve prolapse. Eisenmenger syndrome results from long-term left-to-right shunt, usually at higher shunt volumes. The resulting elevated pulmonary artery pressure is irreversible and leads to a reversal in the ventricular level shunt, desaturation, cyanosis, and secondary erythrocytosis. Endocarditis prophylaxis is not indicated for simple VSD. It is required for 6 months post VSD closure, in patients post VSD closure with a residual shunt and in Eisenmenger patients with R—>L shunt and cyanosis. Show notes - Ventricular Septal Defects Notes (developed by Dr. Anu Dodeja): What are types OF VSD? (Please note that there are several nomenclatures) Perimembranous VSDMost common type of VSD - 80% of VSDsOccurs in the membranous septum and can be associated with inlet or outlet extensionLocated near the tricuspid and aortic valves, often time can be closed off by tissue from the septal leaflet of the tricuspid valve and associated with abnormalities in the septal leaflet of the tricuspid valve secondary to damage from the left to right shuntCan be associated with acquired RVOTO, double chamber right ventricle, LVOTO/sub aortic membrane formation On TTE, the parasternal short axis view at the base demonstrates this type of VSD at the 10-12 o’clock position. Muscular VSDSecond most common VSD - 15-20% of VSDsCompletely surrounded by muscle,
