Abstract
The technique of normothermic caval inflow occlusion was introduced more than 50 years ago, and it was well established and used extensively before the era of cardiopulmonary bypass. It had been used in various cardiac situations where a period of up to 2 minutes of intracardiac exposure was sufficient. However, this technique was rarely used recently, especially for adult cardiac procedures. Almost every open heart surgery was performed under the assistance of cardiopulmonary bypass which provided a motionless and bloodless surgical field. Here we report our experience of tricuspid valve surgery using caval inflow occlusion in adults. Three infective endocarditis patients with multiple pulmonary emboli, congestive heart failure and uncontrolled sepsis underwent tricuspid valve vegetectomy without cardiopulmonary bypass. Right atria were opened and infected leaflets were excised after occlusion of both vena cava. All these patients had good recovery. The detailed surgical managements were described.
