OBJECTIVES: Critical aortic valve stenosis (CAS) in the newborn is treated by balloon or surgical aortic valve intervention with nearly equal success, but the subset of patients with severe left ventricular (LV) dilation and dysfunction present a significant mortality risk. We describe a two-stage surgical management approach for those infants who represent an unusually high failure risk for ei...

Conflicting views have been expressed regarding the advisability of mitral valvotomy in pregnancy. Little attention has been paid to the effect of pregnancy on the deterioration in cardiac status subsequent to mitral valvotomy. This study has been undertaken in an effort to clarify these two issues. Before June 1963, 903 patients under the care of one of us (J.F.P.) had mitral valvotomy. Of the...

Percutaneous balloon dilatation was attempted in 15 consecutive neonates (mean age 7.3 (range 1-27) days and weight 3.2 (range 2.5-4.1) kg) with critical stenosis of the pulmonary valve. Dilatation was successful in 11 (73%) patients. The mean balloon to annulus ratio was 1.1 (range 0.6-1.77). The ratio of right ventricle to femoral artery systolic pressure decreased from a mean (1 SD) of 1.4 (...

Posterior urethral valve is the commonest cause of both urinary tract obstruction and chronic renal disease in male children. The patients may present with complications such as impaired function, infection, or anaemia. Reports abound about association other congenital defects posterior but few studies have reported this osteogenesis imperfecta. An 8-year-old on management for imperfecta who pr...

Percutaneous mitral balloon valvotomy (PMV) has been accepted as an alternative to surgical mitral commissurotomy in the treatment of patients with symptomatic rheumatic mitral stenosis. Previous studies have demonstrated that PMV produces good immediate and long-term follow-up results in a selected group of patients with mitral stenosis.1-4 Hemodynamic and clinical improvement is achieved in t...

The results of transventricular mitral valvotomy in 50 cases of heavily calcified mitral stenosis are presented. The mortality and quality of results in patients undergoing a first valvotomy were more satisfactory than in patients undergoing a second operation. Associated mitral incompetence has an adverse effect on the results, particularly after a second operation. As a result, it is suggeste...
