A case report of cardiac allograft vasculopathy complicated with coronary vasospasm: insights from near-infrared spectroscopy, intravascular ultrasound, and optical coherence tomography

ABSTRACT: Abstract

Background

Cardiac allograft vasculopathy (CAV) remains a major complication after heart transplantation. Although coronary vasospasm after heart transplantation has occasionally been reported, the association between CAV and coronary vasospasm remains unclear.

Case summary

A 68-year-old male with a history of heart transplantation 21 years ago presented with atypical angina. Coronary angiography demonstrated intermediate stenoses in the proximal and mid left anterior descending artery (LAD) and right posterolateral artery. Intracoronary acetylcholine provocation testing resulted in subtotal occlusion of the coronary arteries bilaterally, which was resolved by nitroglycerine administration, but the intermediate stenoses remained. The stenosis in the proximal LAD
