A 30-year-old man who is a heroin addict was diagnosed with uncontrolled tricuspid valve endocarditis and repeated lung abscesses. He underwent tricuspid valvectomy for the endocarditis. After surgery the patient had severe tricuspid regurgitation and hypoxemia develop. Due to severe tricuspid regurgitation-induced ventricular distension and persistent low cardiac output, reimplantation of the tricuspid valve was planned for 2 weeks after the first operation. To avoid lung injury caused by the cardiopulmonary bypass and to preserve right ventricular function, a self-made superior and inferior vena cava shunt was connected to the pulmonary artery. The tricuspid valve was implanted without cardiopulmonary bypass.
