Infective Endocarditis Surgery Using Conventional Prosthetic Valves Versus Cryopreserved Aortic Homograft

The target population enrolled in the study includes patients with aortic-valve endocarditis at risk of embolization, heart failure and uncontrolled infection undergoing AVR with the use of CAH or conventional mechanical or stent xenograft valve prostheses. Individuals were adequately treated per applicable standards, including for the treatment of infection, LV dysfunction and heart failure. Patients enrolled in the studies were NYHA functional class II, III, or outpatient NYHA IV. Three groups of patients are included in the study. Patients who were managed with CAH, patients who received AVR with conventional stented xenograft and recipients of AVR undergoing surgery with the use of mechanical prostheses.
