Changing Hemodynamics in Patients with Transposition of the Great Arteries

Changing hemodynamics in patients with transposition of the great arteries.

Follow-up cardiac catheterizations were carried out on 65 patients with transposition of the great arteries. Patent ductus arteriosus (PDA) was a significant problem in this group only when closure resulted in a precipitous drop in arterial oxygen saturation. Spontaneous closure of ventricular septal defects (VSD) occurred in approximately 20% of patients while natural or surgically created atr...

A 33-day-old Infant with the Transposition of the Great Arteries; A Rare Case Report

Dextro-transposition of the great arteries (d-TGA) is the one most common cyanotic congenital heart disease in neonates. The discordant ventriculoarterial arrangement results in parallel circulation, it so is vital to understand the management. We report a rare interesting but critical case of 33-day-old boy who developed cyanosis and had transposition of great arteries combined with interrupte...

Transposition of the great arteries

Transposition of the great arteries (TGA), also referred to as complete transposition, is a congenital cardiac malformation characterised by atrioventricular concordance and ventriculoarterial (VA) discordance. The incidence is estimated at 1 in 3,500-5,000 live births, with a male-to-female ratio 1.5 to 3.2:1. In 50% of cases, the VA discordance is an isolated finding. In 10% of cases, TGA is ...

Transposition of the great arteries.

Many patients with ventriculoarterial discordance have survived to adulthood. Those with complete transposition of the great arteries have often had an atrial switch procedure (Mustard or Senning operation) performed, which leaves the morphological right ventricle (RV) supporting the systemic circulation. RV failure and tricuspid regurgitation are common. Some patients may ultimately require ca...
