259. Guidelines: 2022 AHA/ACC/HFSA Guideline for the Management of Heart Failure – Question #6 with Dr. Randall Starling

The following question refers to Section 7.4 of the 2022 AHA/ACC/HFSA Guideline for the Management of Heart Failure. The question is asked by New York Medical College medical student and CardioNerds InternAkiva Rosenzveig, answered first by Cornell cardiology fellow and CardioNerds AmbassadorDr. Jaya Kanduri, andthen by expert faculty Dr. Randall Starling.

Dr. Starling is Professor of Medicine and an advanced heart failure and transplant cardiologist at the Cleveland Clinic where he was formerly the Section Head of Heart Failure, Vice Chairman of Cardiovascular Medicine, and member of the Cleveland Clinic Board of Governors. Dr. Starling is also Past President of the Heart Failure Society of America in 2018-2019. Dr. Staring was among the earliest CardioNerds faculty guests and has since been a valuable source of mentorship and inspiration. Dr. Starling’s sponsorship and support was instrumental in the origins of the CardioNerds Clinical Trials Program.

TheDecipher the Guidelines: 2022 AHA / ACC / HFSA Guideline for The Management of Heart Failureseries was developed by the CardioNerds and created in collaboration with the American Heart Association and the Heart Failure Society of America. It was created by 30 trainees spanning college through advanced fellowship under the leadership of CardioNerds CofoundersDr. Amit GoyalandDr. Dan Ambinder, with mentorship fromDr. Anu Lala,Dr. Robert Mentz, andDr. Nancy Sweitzer. We thank Dr. Judy Bezanson and Dr. Elliott Antman for tremendous guidance.

Question #6

Mr. D is a 50-year-old man who presented two months ago with palpations and new onset bilateral lower extremity swelling. Review of systems was negative for prior syncope. On transthoracic echocardiogram, he had an LVEF of 40% with moderate RV dilation and dysfunction. EKG showed inverted T-waves and low-amplitude signals just after the QRS in leads V1-V3. Ambulatory monitor revealed several episodes non-sustained ventricular tachycardia with a LBBB morphology.

He was initiated on GDMT and underwent genetic testing that revealed 2 desmosomal gene variants associated with arrhythmogenic right ventricular cardiomyopathy (ARVC).

Is the following statement true or false?

“ICD implantation is inappropriate at this time because his LVEF is >35%”

True

False

Answer #6

Explanation
This statement is False. ICD implantation is reasonable to decrease sudden death in patients with genetic arrhythmogenic cardiomyopathy with high-risk features of sudden death who have an LVEF ≤45% (Class 2a, LOE B-NR).
