Cardiovascular diseases (CVD) are the leading causes of death and disability in the world. Among all CVD, the most common is coronary artery disease (CAD). CAD results from the complications promoted by atherosclerosis, which is characterized by the accumulation of atherosclerotic plaques that limit and block the blood flow of the arteries involved in heart oxygenation.

Methods: From 1997 to 2017, a total of 142 patients underwent surgery using the Ross procedure. The development of moderate-severe stenosis (peak transhomograft pressure gradient 36 mm Hg or greater) and surgical or percutaneous Ross homograft reinterventions were evaluated by echocardiography in the immediate postoperative period and at annual intervals.
Traditionally, when antibody to the Hepatitis B core antigen (anti-HBc) and antibody to the Hepatitis B surface antigen (anti-HBs) are positive, the donor is considered suitable. However, the literature contains cases with this profile and circulating hepatitis B virus DNA. The aim of the study is to analyze the incidence of occult hepatitis B virus infection (OBI).

Patients And Method: All patients were evaluated at 3, 6 and 12 months, and annually thereafter. Patients with a transhomograft pressure gradient greater than 30 mmHg were referred for cardiac magnetic resonance imaging.
