Left coronary artery originating from the pulmonary artery correction and total myocardial blood flow measurements

In a boy aged 12 years correction of an anomalous coronary artery system was performed by suture of the left coronary artery origin at the pulmonary artery trunk and a vein by-pass to the proximal LAD. Peroperative blood flow gives values for myocardial perfusion before and after by-pass with relati...

Summary:In a boy aged 12 years correction of an anomalous coronary artery system was performed by suture of the left coronary artery origin at the pulmonary artery trunk and a vein by-pass to the proximal LAD. Peroperative blood flow gives values for myocardial perfusion before and after by-pass with relation to patency of the vein graft. Before correction pure coronary blood flow was 540 ml/min, shunt flow 540 ml/min; in total 1,080 ml/min through the right coronary artery. After correction the vein by-pass conducted 310 ml/min and the right coronary artery 180 ml/min. At follow-up 2 months later coronary angiography showed a normal right coronary artery without collateral connections to the left coronary artery system which was well perfused from the by-pass. Left heart hypertrophy was reduced from 568 ml/m2. A weak systolic murmur at the apex could be a slight unimportant mitral insufficiency.
