A clinical study of intermediate changes after modified blalock taussig shunt in patients of tetralogy of fallot and its significance for intracardiac repair

Congenital cyanotic heart diseases (CCHD) especially cyanotic spells require urgent assessment and treatment either medical or surgical intra-cardiac repair in view of the wide spectrum of anatomic variation. The prognosis of the disease, morbidity and mortality was high requiring special expertise and setup. Presence or absence of Patent Ductus decides the morbidity and mortality. Prostaglandins (PGE-1) can reopen and maintain patency of ductus arteriosus in neonates reducing the urgency of performing shunts and allowing resuscitation of the patients preoperatively. This study was thus done to show the interim changes that take place after the palliative surgery and thus preparing the patient for intra-cardiac repair. 40 patients with post Modified B T Shunt were studied with follow up for 5 years and to show the improvement of the various clinical features, and the favorable effects on patient condition and the long term beneficial results of the procedures.
