Quadrivalvular Heart Disease Complicated by Fatal Infective Endocarditis of Pulmonary Valve: A Case Report.

A middle-aged sick male with rheumatic heart disease and prior mitral and aortic prosthesis was admitted for tricuspid valve replacement. Preoperative assessment revealed a hitherto undiagnosed pulmonic condition. This unusual case is reported not only to highlight the quadrivalvular disease with possible coexisting rheumatic and congenital etiology but also the fulminant endocarditis of pulmonary valve.
