[Function of the right ventricle in patients with mitral valve diseases].

To investigate right ventricular function in mitral valve disease, biplane cineventriculograms of the right and left ventricle were performed in 96 patients-35 with mitral stenosis, 26 with mitral regurgitation, 12 with combined mitral valve disease, 14 with mitral stenosis and tricuspid regurgitation, and nine with mitral regurgitation and tricuspid regurgitation, compared to 18 normals (N). Right ventricular enddiastolic volume index was moderately elevated in patients with mitral stenosis and concomitant tricuspid regurgitation (111.6 +/- 35.3 ml/m2, no significance compared to N: 95.9 +/- 21.8 ml/m2) and with mitral regurgitation and tricuspid regurgitation (107.9 +/- 45.1 ml/m2, no significance compared to N). A reduced right ventricular ejection fraction (RVEF less than or equal to 50%) was found in 40 of the 96 patients. Right ventricular ejection fraction was frequently reduced in patients with mitral regurgitation and tricuspid regurgitation (46.7% +/- 15.1%) and significantly reduced in patients with combined mitral valve disease (45.0 +/- 17.6%, compared to N: 58.0 +/- 7.1%, p less than 0.01). No significant correlations were found between right ventricular ejection fraction and left ventricular enddiastolic volume or left ventricular ejection fraction in patients with mitral valve disease. Moreover, right ventricular ejection fraction did not correlate with systolic pulmonary artery pressure, mean pulmonary artery pressure or mean pulmonary capillary wedge pressure. Local wall motion (mean systolic shortening) was determined for the anterior, anteroapical, and inferior segment in the RAO-projection and for the right ventricular free wall in the LAO-projection. 63% of the patients (n = 25) with reduced right ventricular function (RVEF less than of equal to 50%) showed local wall motion abnormalities, preferably in the anterior segment of the RAO- projection (48%) and the right ventricular free wall (30%).(ABSTRACT TRUNCATED AT 250 WORDS)

Fate of tricuspid regurgitation after closed valvotomy for mitral stenosis.

Rheumatic mitral valve disease is not infrequently associated with tricuspid regurgitation (TR). To determine the fate of TR following closed mitral valvotomy (CMV), we examined the records of 23 patients with variable degrees of TR and significant mitral stenosis (MS). Based on angiocardiographic assessment of TR, patients were divided into two groups: group 1 (15 patients) had mild-to-moderate TR, while group 2 (eight patients) had severe TR. After valvotomy, dyspnea lessened in all patients. Right ventricular (RV) failure signs (jugular venous distension and hepatomegaly) and the amounts of diuretics used diminished in 12 of 15 patients in group 1. Group 2 patients showed insignificant improvement at one-year follow-up period. Cardiac recatheterization was performed in four of group 2 patients three to five years later primarily for persistence of RV failure signs. The mitral valve areas varied from 1.4 to 2.7 cm2. There was mild mitral regurgitation in two patients. There was no deterioration of the left ventricular ejection fraction, but TR was at least moderate in all cases.

Acquired right heart outflow tract anomaly without systemic hypertension in recipient twins in twin-twin transfusion syndrome.

Significant hemodynamic changes are commonly observed in both fetuses in twin-twin transfusion syndrome. In the recipient twin there is cardiac dysfunction with hypertrophy of both ventricles and overall enlargement of the heart. We describe five cases of recipient twins in twin-twin transfusion syndrome with right ventricle hypertrophy, pulmonary stenosis and tricuspid regurgitation acquired in utero. These symptoms developed with no signs of systemic hypertension. Three of the five recipient twins survived and were developing normally at 3-30 months of age. Postnatal outcome is likely to have improved as a result of prenatal diagnosis of right ventricle outflow tract obstruction and timed delivery. These acquired anomalies of the right heart might be related to the particular hemodynamic conditions of the recipient twin. A global heart dilatation is logically expected, but this hypertrophy without dilatation is probably related to the shared plasma of fetuses with opposite hemodynamic conditions. This is what we consider as the hemodynamic-hormonal paradox. These acquired anomalies, though severe, are accessible to neonatal treatment if treated early.

Systolic anterior motion of the tricuspid valve in idiopathic hypertrophic subaortic stenosis.

A 37 year man with combined subpulmonic and subaortic idiopathic hypertrophic stenosis proved by cardiac catheterization had typical echocardiographic findings of idiopathic hypertropic subaortic stenosis (IHSS) and systolic anterior motion of the anterior leaflet of the tricuspid valve. This motion of the tricuspid valve may relate to the subpulmonic infundibular gradient in the same way that the systolic anterior motion of the anterior mitral leaflet relates to the subaortic left ventricular gradient in patients with IHSS.
