CardioNerds (Amit Goyal & Daniel Ambinder) join University of California San Diego (UCSD) cardiology fellows (Harpreet Bhatia, Dan Mangels, and Quan Bui) for a relaxing beach bonfire in the beautiful city of San Diego! They discuss a challenging case of post-transplant cardiac allograft vasculopathy. Dr. Hao (Howie) Tran provides the E-CPR and program director Dr. Daniel Blanchard provides a message for applicants. Episode notes were developed by Johns Hopkins internal medicine resident Richard Ferraro with mentorship from University of Maryland cardiology fellow Karan Desai.   Jump to: Patient summary - Case media - Case teaching - References The CardioNerds Cardiology Case Reports series shines light on the hidden curriculum of medical storytelling. We learn together while discussing fascinating cases in this fun, engaging, and educational format. Each episode ends with an “Expert CardioNerd Perspectives & Review” (E-CPR) for a nuanced teaching from a content expert. We truly believe that hearing about a patient is the singular theme that unifies everyone at every level, from the student to the professor emeritus. We are teaming up with the ACC FIT Section to use the #CNCR episodes to showcase CV education across the country in the era of virtual recruitment. As part of the recruitment series, each episode features fellows from a given program discussing and teaching about an interesting case as well as sharing what makes their hearts flutter about their fellowship training. The case discussion is followed by both an E-CPR segment and a message from the program director.

On presentation, he was normotensive and borderline tachycardic. Exam revealed elevated JVP, decreased breath sounds, and pitting edema.  Labs demonstrated leukocytosis, acute kidney injury, and elevated pro-BNP. TTE demonstrated LVEF 35%, apical akinesis, and grade III diastolic dysfunction (all similar to prior). He was initially diuresed and RHC/EMB was performed to evaluate for rejection. Early in his course, the patient unfortunately suffered a PEA arrest with ROSC was quickly achieved after 1 minute of CPR. He was intubated and cannulated for VA ECMO. EMB demonstrated ISHLT Grade 1R cellular rejection and he was ultimately listed for re-transplant. Shortly thereafter, the patient received an OHT. His pathology demonstrated intimal thickening of all his coronaries, consistent with coronary artery vasculopathy, felt to be the major contributor to his presentation.   Case Media ECG Episode Schematics & Teaching Click to enlarge! The CardioNerds 5! – 5 major takeaways from the #CNCR case 1. What is CAV?   CAV stands for cardiac allograft vasculopathy. Within the transplanted heart, CAV is the proliferation of vascular smooth muscle and intimal thickening in the epicardial coronary arteries and microvasculature leading to diffuse narrowing. CAV is common, present in greater than 30% of patients at 5 years post-transplant. It is a significant contributor to post-transplant mortality after the first year.  CAV, in contrast to typical atherosclerotic lesions, is diffuse and concentric while atherosclerosis tends to be focal with eccentric luminal narrowing and heterogenous plaque composition. Patients s/p OHT can still develop typical coronary artery disease,
