coronary artery disease is the leading cause of death worldwide. in this study, we compared two surgical methods of left internal mammary artery (lima) anastomosis on left anterior descending (lad) artery in patients with severe diffuse lesions. a total of 40 patients were included in our study and randomly assigned into two groups. in group a, after a long arteriotomy on lad, the posterior sur...

BACKGROUND The left internal mammary artery (LIMA) to left anterior descending coronary artery (LAD) graft is the most important graft in coronary artery bypass graft surgery.1 The length of the LIMA is fixed and situations may arise when this is inadequate.2 This may not be apparent during the cardiopulmonary bypass until after the anastomosis has been performed and the lungs re-expanded. We d...

Inadvertent left internal mammary artery (LIMA)-great cardiac vein (GCV) anastomosis is a rare complication of coronary artery bypass graft surgery. Patients with iatrogenic aortocoronary fistula (ACF) were usually treated surgical repair, percutaneous embolic occlusion with coil or balloon. We report a case of iatrogenic LIMA to GCV anastomosis successfully treated with coil embolization and p...

To determine the impact of left anterior descending-competitive flow (LAD-CF) on distal coronary flow (LAD-DF) and on left internal mammary artery-graft flow (LIMA-GF), we performed a quantitative blood-flow analysis in a swine model of a LIMA-to-LAD coronary artery bypass graft (CABG). In six swine, a LIMA-to-LAD CABG was performed. LAD blood-flow was measured bilaterally to the LIMA-to-LAD an...

BACKGROUND Although techniques for off-pump coronary artery bypass grafting (CABG) are continually being refined, angiographic follow-up studies have indicated a higher rate of anastomoses-related stenoses than expected after traditional on-pump CABG. This study was performed to evaluate the use of intraoperative epicardial color Doppler ultrasound to quality-assess left internal mammary artery...

There is higher long-term failure of the saphenous vein graft (SVG) compared with the left internal mammary artery (LIMA) graft, which is affected by the hemodynamic environment. A comprehensive analysis of postoperative structure-function changes is important to study the atherogenesis in the SVG A comparison of morphometric and hemodynamic parameters was carried out between LIMA grafts and SV...

Background: The current study reviews clinical feasibility experiences evaluating safety and efficacy of using robotic assistance to create a left internal mammary artery to left anterior descending artery (LIMA-to-LAD) anastomosis. Methods: Between August and November 1999, 9 patients (aged 54-73 years) underwent robotically assisted endoscopic coronary artery bypass grafting (E-CABG) after in...

Taking the transfemoral approach when performing a left internal mammary artery (LIMA) graft intervention is generally recognized as posing significant technical challenges. However, little has been reported on alternative transradial approaches to LIMA. In this report, we present our experience in a patient who had anastomosis-site LIMA graft stenosis and was successfully treated with direct s...

Coronary artery disease is the leading cause of death worldwide. In this study, we compared two surgical methods of left internal mammary artery (LIMA) anastomosis on left anterior descending (LAD) artery in patients with severe diffuse lesions. A total of 40 patients were included in our study and randomly assigned into two groups. In group A, after a long arteriotomy on LAD, the posterior sur...

BACKGROUND We investigated in a porcine model whether measuring both the flow distal to an anastomosis and the graft transit time flow (TTF) gives a more accurate picture of the true blood flow in the left anterior descending artery (LAD) than graft TTF measurement alone. METHODS We performed off-pump coronary artery bypass grafting (CABG)-left internal mammary artery (LIMA) to the LAD-on 5 Y...
