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

This case highlights the potential association between CAV and coronary vasospasm. Intravascular imaging detected similarities in plaque morphology between CAV and coronary vasospasm, suggesting that coronary vasospasm might contribute to the development of CAV. Although coronary vasospasm may be underdiagnosed in heart transplant recipients due to the lack of symptoms involving the denervated heart, this case showed that appropriate provocation testing may be beneficial for evaluating the cause of CAV.
