Summary of "Role of flowmetry in tactics of bypass grafting for myocardial bridge of the anterior descending artery."

The purpose of the study was to analyse the remote results of bypass grafting for myocardial bridges. Our retrospective single-centre study included a total of 17 patients subjected to coronary bypass grafting of the anterior descending artery (ADA) in connection with a detected myocardial bridge (MB). All patients underwent assessment of the coronary bypass grafts (CBG) by means of intraoperative flowmetry - transit time flow measurement (TTFM), as well as angiographic control of the CBGs in the remote period. The duration of follow up amounted to 72 months. Six patients were found to have pronounced retrograde blood flow accompanied by an elevated index of peripheral resistance (Pi) and decreased mean volumetric blood flow velocity (Qmean) below the threshold values. Compression of the ADA proximal to the anastomosis appeared to be followed by improvement of blood flow parameters, in connection with which the shunted artery was ligated with monofilament polypropylene suture 4/0. According to the findings of coronary bypass angiography (CBA) the following results were obtained: 4 occluded grafts were revealed in the group of patients in whom ligation of the ADA was not performed. In patients subjected to ADA ligation in connection with pronounced retrograde blood flow, all bypass grafts were competent. The cumulative probability of freedom from graft occlusion was significantly higher in the group of patients subjected ADA ligation proximal to the anastomosis (Log Rank=0.032).

Medical and Biotech [MESH] Definitions

A malformation that is characterized by a muscle bridge over a segment of the CORONARY ARTERIES. Systolic contractions of the muscle bridge can lead to narrowing of coronary artery; coronary compression; MYOCARDIAL ISCHEMIA; MYOCARDIAL INFARCTION; and SUDDEN CARDIAC DEATH.

MYOCARDIAL INFARCTION in which the anterior wall of the heart is involved. Anterior wall myocardial infarction is often caused by occlusion of the left anterior descending coronary artery. It can be categorized as anteroseptal or anterolateral wall myocardial infarction.

Abdominal artery that follows the curvature of the stomach. The right gastroepiploic artery is frequently used in CORONARY ARTERY BYPASS GRAFTING; MYOCARDIAL REVASCULARIZATION, and other vascular reconstruction.

Inferior and external epigastric arteries arise from external iliac; superficial from femoral; superior from internal thoracic. They supply the abdominal muscles, diaphragm, iliac region, and groin. The inferior epigastric artery is used in coronary artery bypass grafting and myocardial revascularization.

An extra-anatomic method of surgical revascularization in which the AXILLARY ARTERY is anastomosed to FEMORAL ARTERY.
