Double disposition of the major vessels from the right ventricle of the Fallot tetralogy type

摘要

Forty-six patients with double disposition of the major vessels from the right ventricle in combination with stenosis of the pulmonary artery, in sub-aortal and bi-committed defects of the interventricular septum have undergone biventricular intraventricular correction. The most specific and accurate anatomic characteristics were: 1) position of the major vessels (particularly side-to-side); 2) location of two and a part of the third aortal sinuses above the right ventricle; 3) bilateral cone; 4) absence of aorto-mitral contact; 5) location of valves of aorta and pulmonary artery on the same level. One (2,2%) patient died during surgery due to progressed cardiac insufficiency. One (2,5%) patient died 2 years after radical correction of the defect due to progressive dysfunction of the right ventricle. tetrady Fallot.
