BACKGROUND The aim of this study was to assess a novel transthoracic echocardiographic method to estimate the severity of pulmonary regurgitation (PR) in patients with surgically repaired tetralogy of Fallot. METHOD In 63 patients with operated tetralogy of Fallot, PR was evaluated by vena contracta width, jet deceleration, PR index, pressure half-time,(More)
OBJECTIVES To compare the Lecompte technique and the spiral anastomosis (complete anatomic correction) two decades after arterial switch operation (ASO). METHODS Nine patients after primary ASO with Lecompte and 6 selected patients after spiral anastomosis were evaluated 20.8 ± 2.1 years after ASO versus matched controls. Blood flow dynamics and flow(More)
Methods As a part of comprehensive CMR examination myocardial extracellular volume fraction (ECV) was calculated from pre-and postgadolinium contrast T1 measurements of blood and myocardium (Look-Locker technique) in 25 asymptomatic patients (age:18.9±7.6) with aortic coarctation after surgical repair and 10 agematched controls. Parameters of ventricular(More)
BACKGROUND Patients with hypoplastic left heart syndrome after a Norwood operation show dilatation and reduced distensibility of the reconstructed proximal aorta. Cardiac magnetic resonance imaging (CMR) and angiographic examinations indicate that the native descending aorta (DAo) is also dilated, but this has not been studied in detail. METHODS AND(More)
OBJECTIVES Since 1996, our centre performs restrictive enlargement of the pulmonary annulus at surgical repair of tetralogy of Fallot. A transannular patch is only used if the z-score of the pulmonary annulus is smaller than -2. We sought to determine whether this strategy reduces pulmonary insufficiency (PI) and reoperation rate compared to a nationwide(More)
BACKGROUND The increased cardiovascular morbidity of adults with late repair of aortic coarctation (CoA) has been well documented. In contrast, successful CoA repair in early childhood has a generally good prognosis, though adverse vascular and ventricular characteristics may be abnormal, which could increase long-term risk. This study sought to perform a(More)
Methods 79 children with HLHS in Fontan circulation (6.3±3.2 years) and 18 controls (6.8±2.4 years) underwent 3.0 Tesla cardiovascular magnetic resonance imaging. Gradient-echo cine and phase-contrast imaging was applied to measure cross-sectional areas, distensibility and pulse wave velocity (PWV) of the entire thoracic aorta, particularly the DAo.(More)
Background Recent independent approaches have been presented to describe and quantify particular properties of blood flow using MRI. However, the fluid dynamic data acquired with 4D phase contrast involve complex flow patterns that motivate a systematic, comprehensive analysis of various quantities in a single software tool. For the hemodynamics, an(More)
Methods 31 patients (20.6 ± 10.3 years) underwent an MRI examination before and after (20 ± 18 months) pulmonary valve replacement or reconstruction (PVR) for the volume overload of the RV. For segmental analysis of the RV, a custom made analysis software was developed. The method provides an automatic contour detection algorithm for the determination of(More)
