Abstract Objectives: We aimed (1) determine if systemic right ventricle filling parameters influence
systemic right ventricle stroke volume in adult patients with D-transposition of the great arteries
(D-TGA) palliated by atrial switch, using cardiac magnetic resonance imaging and echocardiography, and (2) to study relationship of these diastolic parameters with exercise performance and
BNP, in patients with preserved systolic systemic right ventricle function.
Design: Single-center, cross-sectional, prospective study.
Setting: In patients with D-TGA palliated by atrial switch, diastolic dysfunction of the systemic
right ventricle may precede systolic dysfunction.
Methods: Forty-five patients with D-TGA and atrial switch and 45 age and sex-matched… More >
