OBJECTIVES The results of percutaneous balloon angioplasty for obstructed modified Blalock-Taussig (BT) or central shunts and pulmonary artery (PA) stenoses were studied to assess its role as an alternative to second shunt and surgical PA angioplasty. BACKGROUND Obstruction of a modified shunt and PA stenosis related to the shunt or ductus are not infrequent. A second shunt with or without PA...

OBJECTIVE Despite that surgical outcomes of patients with hypoplastic left heart syndrome have improved, one of the problems remaining is the high interstage mortality after a stage I Norwood procedure. The purpose of this study was to determine the hemodynamic characteristics of hypoplastic left heart syndrome after a Norwood procedure. We examined the perioperative hemodynamic differences of ...

Pulmonary artery growth after a systemic-pulmonary shunt was angiographically evaluated in 19 out of 35 patients. The mean age of the subjects at the time of the initial operation was 18+/-18 months including 12 patients under a year old. The preoperative diagnosis was tetralogy of Fallot (TOF) in 10 patients, TOF plus pulmonary atresia in five and transposition of great arteries in four. A Bla...

OBJECTIVES Transventricular valvotomy is a kind of hybrid therapy that is widely used in developing countries where cardiac catheter intervention is limited in neonates. The purpose of this study was to evaluate the surgical outcomes and effectiveness of transventricular valvotomy in neonates with pulmonary atresia and an intact ventricular septum. METHODS Between August 2008 and July 2013, 2...

BACKGROUND The prognosis for hypoplastic left heart syndrome (HLHS) has greatly improved over the past years, but there is still a significant risk of interstage mortality. Tricuspid valve regurgitation (TR) is known to be a risk factor for interstage mortality. We hypothesized that a modified Blalock-Taussig (BT) shunt with a smaller diameter would lead to a reduction in ventricular volume loa...

Background: Studies on predictors of health-related quality life (HRQOL) in pediatric patients with cyanotic heart disease who are waiting for the next stage and those have undergone total repair scarce. Therefore, we aimed to identify such children received modified Blalock–Taussig shunt (MBTS) underwent repair. Methods: In this historical cohort concurrent follow-up study, data MBTS at age 0–...
