31 pts who underwent arterial switch at a weight of 2.5 kg or less were evaluated for outcomes. Surgery was performed at an average of 16 days of life. Mortality was 2.8% for those weighing 2.0-2.5 kg, and was 50% for those under 2 kg. At a mean follow-up of 13 years, 8% had required late reoperation.

Transposition of the great arteries

This video demonstrates the use of computational fluid dynamics after performing the Rastelli procedure.

The authors evaluated long-term outcomes of 468 patients who have undergone a Mustard- or Senning operation for transposition of the great arteries (TGA). They found that perioperative mortality was 30%, but 60% were still alive after 30 years of follow-up.

Nick Albus had transposition correction as a child and had to have a second operation in 2013. Now he is pushing to get in the state champoinships at 100m. Read his story here.

The impact of center and surgeon volume on outcomes after arterial switch for TGV was investigated using data from the STS database. Median center and surgeon annual volumes were 4 and 2. Both center and surgeon volume were important determinants of the composite outcome (death or major complication), with surgeon volume having the most important e

This study compared early and intermediate biventricular function after early arterial switch in 26 infants and 20 age-matched controls. At 1 year LV performance was similar in ASO and controls, whereas RV systolic and diastolic function remained impaired. This stresses the need for ongoing monitoring of RV function after ASO.

In the second videoclip exploring congenitally corrected transposition, we show a specimen in which the potentially corrected circulatory patterns are uncorrected to a degree by the presence of a ventricular septal defect.

In one-third of patients with congenitally corrected transposition, there can be co-existing pulmonary stenosis. As explained, although it is stated that no heart exists in the Idriss archive with this lesion, this is not the case, and such a heart in shown in the next video clip.

We first demonstrate the key features of congenitally corrected transposition, namely the discordant connections across both the atrioventricular and ventriculo-arterial junctions. The two discordant connections cancel each other out, so that potentially the circulations are congenitally corrected.

In this last video in the series, we examine three specimens with rarer lesions associated with congenitally corrected transposition. The first is an example of a heart with discordant atrioventricular, but concordant ventriculo-arterial connections.
