Arrhythmic Mitral Valve Prolapse (AMVP): What Do We Need to Know? (Joint Session)-Arrhythmic Mitral Valve Prolapse (AMVP): What Do We Need to Know? (Joint Session)

Video Transcription

Video Summary

The session "Arrhythmic Mitral Valve Prolapse, What Do We Need to Know?" was a comprehensive discussion featuring multiple experts discussing the complex aspects of mitral valve prolapse (MVP) and its arrhythmic implications. Dr. Shadi Nakhla initiated the session focusing on the pathophysiology of sudden cardiac death in MVP, highlighting case studies, MRI findings, and discussing the triad of abnormal substrate, triggers, and modulators that contribute to risk.<br /><br />Dr. Andrew Kron and other speakers elaborated on predictors of ventricular arrhythmias, emphasizing deep phenotyping using electrical and imaging parameters, and the need for a robust risk predictor model. They discussed various methods such as echocardiography and cardiac MRI to identify risk factors like myocardial fibrosis and telemechanical dispersion.<br /><br />Dr. Mohit Turagam discussed risk stratification using multimodality imaging, mentioning specific markers like mitral annular disjunction and double-peak strain patterns that signal higher arrhythmic risk. The role of PET-MRI in identifying inflammatory changes was also discussed.<br /><br />Dr. Betsy Kaufman examined the indications for an implantable cardioverter-defibrillator (ICD) in MVP patients, presenting a case that illustrated the complex decision-making involved, and emphasized following expert consensus guidelines while calling for improved risk stratification strategies.<br /><br />Concluding the session, Dr. Pasquale Santangeli discussed the procedural aspects and challenges involved in catheter ablation for arrhythmic MVP patients, focusing on the role of mapping, substrate characterization, and ongoing advances in ablation technology.<br /><br />Overall, the session underscored the need for multimodal assessments and shared decision-making in managing arrhythmic MVP patients. The experts acknowledged the diagnostic challenges and advocated for more robust predictive models to guide clinical decisions.
