(FIT)-Module 2 Lectures: Invasive Diagnosis and Treatment Part 1-Arrhythmias in Patients with Congenital Heart Disease

Video Transcription

Video Summary

Dr. Chris McLeod, a cardiac electrophysiologist at Mayo Clinic, presents a comprehensive overview of arrhythmia management in patients with congenital heart disease. In this heart rhythm board review course, he highlights the importance of recognizing different arrhythmia patterns, such as bradycardia and tachyarrhythmias, and outlines best practices for treatment.<br /><br />Focusing initially on atrial arrhythmias, McLeod emphasizes that atrial arrhythmia is highly prevalent in this patient population due to scar tissue from past surgeries and the altered heart structure. He discusses mechanisms involving reentry facilitated by scars and defects, noting that such conditions are often tied to slow conduction paths. Intracardiac structures and historical surgical interventions significantly influence treatment strategies, making comprehensive imaging crucial for effective management.<br /><br />In addressing ventricular arrhythmias and sudden cardiac death, McLeod differentiates between scar-mediated VT and arrhythmias caused by systemic right ventricular failure. He advises considering scar ablation to prevent recurrent VTs and stresses the importance of regular monitoring and patient education about associated risks.<br /><br />Overall, McLeod advocates for an interdisciplinary approach with continual reassessment of clinical guidelines, emphasizing the need for anticoagulation due to the high stroke risk in these patients.
