Overview

Suggests ischemia evaluation for exercise-induced AV block post-CABG; hypothesis-generating, should not yet change practice.

Structured PICO

Does percutaneous coronary intervention resolve exercise-induced atrioventricular block caused by new coronary artery stenosis in a patient with prior CABG?

P
Population
1 patient (n=1), 68-year-old man with a history of coronary artery bypass surgery (CABG) 5 years prior, presenting with pre-syncope on effort and exercise-induced atrioventricular block. Comorbidities include hypertension and hyperlipidemia.
I
Intervention
Percutaneous coronary intervention (PCI) with drug-eluting stents in the right coronary artery (RCA)
O
Outcome
Resolution of exercise-induced atrioventricular block and symptoms

This case demonstrates that exercise-induced atrioventricular block can be a manifestation of new myocardial ischemia and can be successfully resolved with percutaneous coronary intervention.
