[Surgical treatment of patients with post-infarction aneurysm of the left ventricle and diffuse lesion of the anterior interventricular artery].

: Diffuse lesions of the anterior interventricular artery (AIVA) at different levels were diagnosed in 27 out of 417 patients operated for post-infarction aneurysm of the left ventricle (PIALV). During the preoperative period coronography, ventriculography, ultrasonic examination of the heart were made in all the patients, one-photon emission computed tomography with 123I-iodopent was used for radioisotope investigation of perfusion and metabolism of the myocardium. The presence of PIALV, diffuse atherosclerotic lesion of AIVA and viable myocardium in its basin was taken as an indication for autovenous plasty of the artery with the following shunt of the left intrathoracic artery and resection of PIALV.
