Overview
Patients with cardiac allograft vasculopathy (CAV) seldom present with typical angina symptoms due to cardiac denervation at the time of heart transplantation.
History and Symptoms
As mentioned above, patients with cardiac transplants do not typically present with anginal symptoms. About 10-30% of patients regain some renervation to the heart. Hence, they typically present late with the following manifestations.
- Graft failure
- Arrhythmias
- Silent myocardial infarction: Due to denervation at the time of surgery patients with CAV rarely present with typical angina symptoms, especially in the initial years of transplantation.[1] However, studies have demonstrated that re-innervation does occur late after heart transplantation.[2]
- Sudden death
The current practice is to routinely screen cardiac allograft recipients using conventional angiography or intravascular ultrasound (IVUS) as discussed in subsequent sections.
