Abstract:
We report two cases of patients with carcinoid heart disease affecting all four valves. All four of the valves showed signs of regurgitation and were replaced using biological valves. Left-sided involvement is uncommon (5-10%), but can occur in the absence of an intracardiac shunt. Quadruple valve replacement in symptomatic patients can result in functional improvement with acceptable risks.
