    Abstract:
    Invasive data about the frequency and associated factors of tricuspid regurgitation in normals and in patients with aortic and mitral valve disease are still rare. Thus, right ventricular biplane angiograms (RAO/LAO projection), the mean pulmonary artery pressure and the presence of atrial fibrillation were analyzed with regard to tricuspid regurgitation in 30 normals and 165 patients with pure mitral regurgitation, mitral stenosis, aortic regurgitation, aortic stenosis, combined mitral valve disease or combined aortic valve disease. Patients with tricuspid stenosis or coronary artery disease were excluded. In 52 of the 195 patients tricuspid regurgitation was present. Tricuspid regurgitation occurred statistically more often in patients with mitral stenosis (33%), mitral regurgitation (48%) or combined mitral valve disease (68%) than in patients with aortic regurgitation (4%) or combined aortic valve disease (3%). In patients with aortic stenosis and in normals tricuspid regurgitation was not present. In patients with combined mitral valve disease, tricuspid regurgitation was more often present than in patients with pure mitral stenosis (p less than 0.002), despite comparable values of the mean pulmonary artery pressure, the right ventricular enddiastolic and endsystolic volume indexes, the right ventricular ejection fraction and the frequency of atrial fibrillation. Only in patients with pure mitral regurgitation tricuspid regurgitation was associated with an elevated mean pulmonary artery pressure (p less than 0.02). Differences in the right ventricular size and function did not occur between normals and patients with mitral or aortic valve disease. Therefore, the mean pulmonary artery pressure, atrial fibrillation and the size and function of the right ventricle are not major determinants for the occurrence of tricuspid regurgitation.(ABSTRACT TRUNCATED AT 250 WORDS)
