An analysis of mitral stenosis in Burmese patients

ABSTRACT

Based on data derived from 1,055 rheumatic cardiac cases from the Cardiac Clinic and from 506 mitral stenosis patients operated at the Cardiac Unit, Rangoon General Hospital, pure mitral stenosis (MS) in sinus rhythm occurred in only 33 per cent. Association of atrial fibrillation occurred in 35 per cent, of jet mitral incompetence (mi) in 15 per cent, of aortic incompetence (ai) in 13 per cent, of tricuspid incompetence (TI) in 12 per cent, of inaudible mi in 7 per cent, on pulmonary incompetence (PI) in 6 per cent, of both PI and TI in 2 per cent and of jet mi/ai in 2 per cent.Of the 506 mitral valvotomies, there were II with mixed aortic stenosis (as) and incompetence, 4 with/pure aortic stenosis, 4 with Lutembacher's syndrome, 3 with jet mi and mixed aortic stenosis and incompetence, 2 with jet milas, 2 with organic TI and 2 with tricuspid stenosis. Juvenile MS (under 16 years of age) occurred in about 6 per cent. Silent MS occured in 8 instances.
