Heart Transplantation

HIV disease is recognized as an important cause of dilated cardiomyopathy with a reported prevalence of 3.6% among patients with cardiomyopathy, a proportion that is increasing as patients with HIV infection live longer.

The pathogenesis of HIV-related cardiomyopathy is very likely to be multifactorial. HIV-associated sympto­matic heart failure may become one of the leading causes of heart failure worldwide [21]. It explains why, despite a complex pharmacological and immunological status in these patients, several heart transplanta­tions following other solid-organ transplan­tations [28-30] have been reported in HIV­positive recipients (Table 2) [31]. Although Calabrese et al. [32] reported a successful cardiac transplantation in 2003 in an HIV- infected patient with advanced disease, we reserve this therapeutic strategy to well- controlled HIV-positive patients (unde­tectable viral load, CD4 count >400∕mm3)

without opportunistic infection and without a history of Kaposi’s sarcoma. Two cardiac transplantations with a simple postopera­tive course and no specific complications during follow-up have been performed at La Pitie during the last 2 years. A multidisci­plinary team is required for this therapeutic technique because numerous complex and unpredictable pharmacological and immunological adverse events can occur (Fig. 5) [33].

There is no report of a cardiac assist device

in HIV-infected patients, but it is only a matter of time before these devices are used in HIV patients. When the patient is on the waiting list for cardiac transplantation, he or she is eligible for a mechanical bridge. Nevertheless, this therapy will be a chal­lenge because the major complication of ventricular assist devices is sepsis. If the number of HIV-infected patients on waiting lists for cardiac transplantation increases in a high proportion, we should ask the contro­versial question concerning the harvesting of a heart in HIV-infected donors.
