Severity of rheumatic mitral regurgitation.
Thirty patients below the age of 15 years (range 8-1/2 to 15 years, mean 11.8 years) have been studied for the severity of rheumatic mitral regurgitation. Moderately severe to severe pulmonary venous hypertension was found in 76.6% and pulmonary arterial hypertension in 60%. Left ventricular volumes could be calculated in 13 patients. The end-diastolic volume was elevated in 11 and the endsystolic volume in 12 cases. The regurgitant fraction, calculated in nine patients was 0.6 or more in seven cases. The clinical and hemodynamic severity of mitral regurgitation in children was identical to that seen in adults in the absence of active rheumatic carditis. Children with dominant rheumatic mitral regurgitation can develop congestive failure on the basis of valvar damage per se.
