RESUMEN
BACKGROUND: Little has been published regarding surgery for transposition of the great arteries (TGA) in the developing world. OBJECTIVES: This study sought to identify patient characteristics, surgical interventions, institutional characteristics, risk factors for mortality, and outcomes among patients undergoing surgery for TGA in this setting. METHODS: Developing world congenital heart surgical programs submitted de-identified data to a novel international collaborative database as part of a quality improvement project. We conducted a retrospective cohort study that included all cases of TGA with intact ventricular septum and TGA with ventricular septal defect performed from 2010 to 2013. Demographic, surgical, and institutional characteristics and their associations with in-hospital mortality were identified. RESULTS: There were 778 TGA operations performed at 26 centers, 480 (62%) for TGA with intact ventricular septum and 298 (38%) for TGA with ventricular septal defect. Most (80%) were single-stage arterial switch operations, but 20% were atrial baffling procedures (atrial switch operation) or 2-stage repairs (pulmonary artery band followed by arterial switch operation). Age at operation was >30 days in one-half of the cases and did not vary significantly with operation type. Survival was 85% and did not significantly vary with age at operation or operation type. Preceding septostomy was infrequently reported (16%) and was not associated with surgical mortality. Mortality was associated with lower World Health Organization weight/body mass index-for-age percentile and lower institutional volume of TGA repair. CONCLUSIONS: Surgical repair of TGA performed in the developing world is associated with an early survival of 85%. Type of surgical repair and age at operation varied considerably, but no associations with mortality were identified. In contrast, poor nutrition and small surgical volume were most strongly associated with mortality. Multicenter collaborative quality improvement efforts may benefit patients with TGA in the developing world.

Vietnam, in Asia, is a low middle-income country with a relatively large population to cater to. Not many know about Vietnam, or its healthcare sector especially the field of pediatric cardiology and congenital heart disease. In contrast to the developed world, congenital heart disease (CHD) is not diagnosed early. Since most of the patients visit the hospital only in later stages of the disease there are many complications during the operation and post-operatively. But during the past 5 years (from 2009), there has been major improvement in the treatment of CHD, both by intervention and surgery. At present, all kinds of CHD, both simple and complex are being successfully treated in our country. Today in Vietnam, all children under 6 years of age have health insurance coverage, under which almost all operations and catheter interventions are done free in government hospitals. It is helping many patients, especially those from the poor socioeconomic background. However, the present infrastructure is inadequate and a long waiting list has accumulated for treatment of CHD.
RESUMEN
Absence of inferior vena cava is an uncommon congenital abnormality. It is usually associated with other structural anomalies, typically left isomerism. We report a case of interrupted inferior vena cava with azygos continuation diagnosed as an isolated finding during routine prenatal ultrasound scan, confirmed by post-natal echocardiography. Detailed ultrasound examination of the fetal anatomy failed to demonstrate other anomalies. The neonatal course of this fetus was uneventful.
