Abstract


Mitral commissurotomy was performed in fifty two patients with preoperative diagnosis of predominant mitral stenosis by closed operation in forty six cases and open operation _employing pump oxygenator in four cases.
There were one immediate operative ; death and four hospital deaths. Four patients fell in to Group IV and , one in Group Iff Over all operative and hospital mortality rate was about ten per cent.
In five cases mild and moderate degree of mitral regurgitation was created by blind commissurotomy. All had markedly calcified and fibrotic valves.
In seventeen cases (33%) pulmonary artery pressure was raised markedly over 70mmHg . systolic and in twenty moderately elevated. Twenty cases showed moderate or marked pulmonary arterio-and arteriolosclerosis:. Pulmonary hypertension and polmonary vascular changes may affect the immediate operative death rate but not the long-term results:
In early postoperative period forty one patients (79%) showed moderate or,marked improvement subjectively, four unchanged, and two worse.
Eighty six per cent of patients of Group ff & ]J and thirty eight per cent of Group N improved significantly.
In spite that majority of operatively treated patients improvedt subjectively, objective findings including X-ray and ECG showed no consistent or dramatic changes.
Thirty patients were followed for three months to ten years, average of six months. Eighty percent of patients of Group ff and Group ]a and all survived patients of Group W showed good long-term results.
