[Early surgical correction of the left coronary artery with origin at the pulmonary trunk. Late development].
The report of these two cases show the accentuated and progressive increase in the ventricular contractility in the late postoperative period in patients who underwent surgical correction of left coronary artery with origin at the pulmonary trunk. Male and female infants, both developed congestive heart failure not controlled by medical treatment. The diagnosis was made by EKG and confirmed by coronary angiogram. They were surgically treated by translocation of the left coronary artery from the pulmonary artery to the aorta. Nine and seven years later, respectively both patients are free of symptoms with marked recovery of the left ventricle function without alteration in height and weight and in excellent clinical conditions. The early surgical treatment in these cases, even with unfavourable clinical status is the only way to change the natural history of this pathology, with an increase of the ventricular contractility.
