Abstract
Comparison of systemic right ventricular function in transposition of the great arteries after atrial switch and congenitally corrected transposition of the great arteries
Highlights
In patients with transposition of the great arteries corrected by interatrial baffle (TGA) and those with congenitally corrected transposition of the great arteries the right ventricle (RV) is subjected to systemic pressures and fails prematurely
RV shape was similar in the two groups, and there was only a tendency towards a more dilated TGA RV
The RV in TGA and corrected transposition of the great arteries (ccTGA) was more dilated, rounder, and had reduced global and regional function when compared to the normal RV
Summary
In patients with transposition of the great arteries corrected by interatrial baffle (TGA) and those with congenitally corrected transposition of the great arteries (ccTGA) the right ventricle (RV) is subjected to systemic pressures and fails prematurely. We sought to further characterize the geometric, global and regional functional differences between these two groups
