Human heart transplantation started 40 years ago. Medical records of all cardiac transplants performed at Stanford were reviewed. A total of 1446 heart transplantations have been performed between January 1968 and December 2007 with an increase of 1-year survival from 43.1% to 90.2%. Sixty patients who were transplanted between 1968 and 1987 were identified(More)
BACKGROUND The elastic function of the aorta in patients with transposition of the great arteries after arterial switch operation (ASO) is suspected to be important for long-term prognosis. METHODS AND RESULTS Fifty-one patients and 34 controls were studied at 3.0 Tesla with MRI. Forty-three patients (12.8±6.9 years) underwent 1-stage ASO, 8 patients(More)
Background Evaluation of blood flow characteristics in total cavo-pulmonary connection (TCPC) with CMR remains difficult due to its strong modulation by respiration, and is not yet entirely understood. New approaches using 4D phase contrast magnetic resonance imaging (4D PC MRI) are promising and can contribute to the understanding of hemodynamics in the(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)
Thymectomy is often successful as treatment for the autoimmune disease myasthenia gravis. One complication of the operation on such patients is respiratory difficulty especially post-operatively, due to interference with the already disturbed transmission of signals along damaged nerve-endings. Acupuncture anesthesia offers a solution to that problem. In(More)
Background Coronary artery reimplantation is crucial step during the arterial switch (ASO) and Ross operation. Mortality and long-term outcome after the operation mainly depend on the patency and function of the reimplanted coronary arteries due to risk of stenosis, stretching, or occlusion. Cardiovascular magnetic resonance (CMR) imaging has emerged as a(More)
Methods Cardiac magnetic resonance (CMR) was performed at 3.0 Tesla in 109 asymptomatic ToF patients, (age 19.3 ±12.8 years) after surgical correction (16.6±10.0 years post operation), and 64 age-matched controls. Parameters of LV and left atrial (LA) function and aortic distensibility were obtained from cine CMR. In a subgroup (n=50), T1 mapping was used(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)
