The first acute myocardial infarction (MI) of an elderly male was determined through angiography to be due to an infarct of the circumflex artery. The angiogram also revealed chronic occlusion and diffuse disease of the left anterior descending artery (LAD). This had been compensated for by collateral circulation from the right coronary artery. Since the patient had no prior history of coronary...

BACKGROUND The left internal mammary artery (LIMA) is the choice for grafting of the left anterior descending coronary artery (LAD). One possible mechanism of the rare graft failure involve the presence of competitive flow. METHOD 105 patients who had undergone coronary bypass grafting between 1998 and 2000 were included in this observational study. The recatheterizations were performed 28 mo...

The optimal revascularization strategy for multivessel coronary artery disease remains controversial, especially when there is diffuse disease involving the proximal segment of the left anterior descending artery (LAD). Coronary artery bypass graft surgery (CABG) remains the gold standard approach, although the evidence is increasingly being challenged by technological and procedural advances i...

BACKGROUND The coronary arterial lesions of Kawasaki disease are mainly dilative lesions, aneurysms, and stenotic lesions formed before, after, and between aneurysms; these lesions develop in multiple branches resulting in complex coronary hemodynamics. Diagnosis of myocardial ischemia and infarction and evaluation of the culprit coronary arteries and regions is critical to evaluating the treat...

Background We postulated that the late electrophysiological effects of radiofrequency (RF) ablation may be related to microvascular injury extending beyond the region of acute coagulation necrosis. Methods and Results Eighteen RF lesions created in the left anterior descending coronary artery (LAD) perfusion bed of seven open chest anesthetized dogs were studied. The ablation electrode and surr...

Approaches to and outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) the left anterior descending artery (LAD) have received limited study. We examined procedural characteristics patients who underwent LAD CTO between 2012 2022 in a large multicenter PCI registry. The was target vessel 3,059 11,753 PCIs (26%). Overall technical success rates were 89% 88%, respect...
