A 66-year-old Australian man underwent elective replacement of a severely stenotic aortic valve with a 22-mm Medtronic-Hall valve. Six weeks later, he was readmitted with worsening dyspnea, fever, and mild anemia. Investigations confirmed pulmonary edema and moderate periprosthetic aortic regurgitation. The pulmonary edema was managed conservatively, and a second 22-mm Medtronic-Hall valve was implanted. Infective endocarditis was suspected in the aortic annulus below the orifice of the right coronary artery. A bacteriological study revealed a rare bacteria of Streptomyces species. The patient received intensive antibiotic therapy over a 6-week period of hospitalization, and the aortic regurgitation disappeared one week postoperatively.

Access through the right superior pulmonary vein is a commonly used route for left ventricular vent insertion. Complex reshaping of the stylet and vent into a certain position or external guidance do not guarantee successful placement. In this article we describe a modified technique where the stylet sets up the position to allow consistent atraumatic advancement of the catheter across the mitral valve.

Congenital hypofibrinogenemia is a rare condition. We believe that cardiac surgery using cardiopulmonary bypass in a patient with congenital hypofibrinogenemia has not been reported before. We discuss the management in a patient with this condition who successfully underwent an aortic valve replacement and coronary artery bypass grafting.

Advanced prosthetic valve endocarditis is often associated with substantial destruction of the tissues adjacent to the prosthesis. Removal of the infected prosthesis and débridement of the infected tissues make implantation of a new prosthesis challenging. Herein, we discuss successful surgical aortic valve translocation in a 50-year-old man who had advanced acute prosthetic valve endocarditis with destruction of the aortic annulus. One year after being discharged from the hospital, the patient was asymptomatic with good exercise tolerance.
