Treatment of anomalous origin of the left coronary artery from the pulmonary artery in adulthood.
A 47-year-old female patient underwent surgical correction of a recently diagnosed anomalous left coronary artery. The artery originated from the pulmonary artery, and the patient had suffered from pulmonary hypertension and congestive heart failure. The follow-up after 3 and 6 months showed only slight improvement in the patient's condition.

Right atrial temperature and electrical activity during cardioplegic cardiac arrest.
In 18 patients undergoing coronary artery bypass surgery the relation between right atrial temperature and right atrial electrical reactivation during cardioplegic cardiac arrest was studied. The administration of cardioplegic solution induced immediate ventricular and atrial arrest in all patients. No recurrence of ventricular activity was observed while right atrial activity subsequently recurred in 11 patients. Activity at the surface ECG was recorded only in one patient with right atrial reactivation. No right atrial electrical activity was found below 19 degrees C. The average atrial temperature was 21.5 degrees C while the average apex temperature was 15 degrees C. The study has confirmed previous observations that during cardioplegic cardiac arrest the right atrium is not as well protected as the ventricular tissue against rewarming. Monitoring of the right atrial electrical activity or right atrial temperature is essential to ensure atrial arrest during the entire period of cardioplegic cardiac arrest.

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 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.
