ABSTRACT Heart transplantation is the gold standard treatment for patients with end-stage heart failure. The limited availability of organs has led to the expansion of the donor criteria by introducing the use of marginal donors. Although the use of marginal donors has reduced waiting lists, the results are worse than with standard donors. For this reason, the use of marginal donors in clinical practice is still controversial. We describe two cases of heart transplantation from marginal donors with pre-transplant angiography evidence of coronary stenosis and normal ventricular function.

We are very thankful to Dr. Vendramin et al. (1) for their interest in our article about the “off label” use of new cardiac prosthetic valves in different clinical scenarios, and for their thoughtful comments.

We describe two cases of favorable and unexpected recovery in positive patients with COVID-19, suffering from multiorgan comorbidity and already assisted with the left ventricular assist device. We have observed that, although in the presence of more comorbidities, when the maintenance of a valid support of the cardiovascular function is guaranteed, the possibility of successfully overcoming the SARS-CoV-2 infection is still alive.

We describe the case of a 59-year old female affected by aortic extensive endocarditis with communication between aortic annulus and right cavities, treated with double pericardial patch reconstruction and rapid-deployment aortic valve prosthesis implantation.
