Dilatation of the right ventricle and a consecutive enlargement of the tricuspid valve ring are thought to be the main causes of functional tricuspid regurgitation in patients with rheumatic mitral valve disease. To study the effect of right ventricular dilatation as well as the dimension of the tricuspid valve ring, right ventricular volume indices, ejection fraction, regional shortening, pulmonary artery pressure, and the diameter and systolic shortening of the tricuspid valve were determined in 67 patients with rheumatic mitral valve disease (NYHA class II and III) from biplane ventriculographies. Patients with right ventricular enlargement (greater than 90 ml/m2) were divided into groups with (group IIA) and without (group IIB) tricuspid regurgitation and compared with patients with normal right ventricular size and function without tricuspid regurgitation (group I). There was no difference in the end-diastolic volume index, in the afterload or in the diameter of the tricuspid ring. Right ventricular ejection fraction was decreased in group IIA (51 +/- 9% vs. 59 +/- 10% (IIB) and 61 +/- 6% (control); (p less than 0.05). Regional function was also decreased in group IIA. 73% of the patients with tricuspid regurgitation had right ventricular enlargement, but only 44% of the patients with right ventricular enlargement had tricuspid regurgitation. Thus right ventricular dilatation promotes the development of a tricuspid insufficiency, but is not the only cause. Additional factors like decreased local wall motion, alterations of the valve or the valve apparatus may also account for functional tricuspid regurgitation.
