Narrowing of the arteries that supply blood to the heart can lead to heart attacks and death. One way of treating this is to use artery and vein grafts from other parts of the body to bypass the narrowing. However, the blood flow from these grafts "competes" with flow through the natural coronary artery. This may contribute to grafts narrowing with time. This protocol aims to determine the pressure changes responsible for this effect. This could improve our understanding of why some grafts last longer than others.

The purpose of this study is to evaluate long-term outcome of treatment(percutaneous coronary intervention or coronary-artery bypass graft) in unprotected left main coronary artery stenosi...
The purpose of this study is to answer, among others, the following questions: 1) What are the outcomes when using the radial artery as a bypass graft in coronary artery bypass surgery (CA...
Comparison of clinical outcomes in patients undergoing coronary bypass surgery using the heart/lung machine as opposed to using off-pump techniques.
Unprotected left main coronary artery (ULMCA) stenting, offering restoration of a native flow to left coronary artery, is the subject of intense investigations as a potential alternative t...

Coronary artery fistulae (CAF) are rare anomalies with controversial management strategies. The two main treatment options include either surgical repair or catheter embolization. Herein, we report su...
Despite advance in off-pump coronary artery bypass (OPCAB) grafting, there are large debating issues regarding survival benefit between OPCAB and on-pump coronary artery bypass grafting (CABG). The...
Comparative outcomes of coronary-artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) for left main coronary artery (LMCA) disease were previously reported. However, data on very...
Coronary artery bypass grafting remains a viable and successful option for treating high-grade coronary artery stenosis. The postoperative recovery is individual for each patient, but when following l...
Off-pump coronary artery bypass grafting (OPCAB) is one of the standard treatments for coronary artery disease (CAD) while hybrid coronary revascularization (HCR) represents an evolving revascularizat...
Coronary artery bypass surgery on a beating HEART without a CARDIOPULMONARY BYPASS (diverting the flow of blood from the heart and lungs through an oxygenator).
Direct myocardial revascularization in which the internal mammary artery is anastomosed to the right coronary artery, circumflex artery, or anterior descending coronary artery. The internal mammary artery is the most frequent choice, especially for a single graft, for coronary artery bypass surgery.
Surgical therapy of ischemic coronary artery disease achieved by grafting a section of saphenous vein, internal mammary artery, or other substitute between the aorta and the obstructed coronary artery distal to the obstructive lesion.
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.
A complication of INTERNAL MAMMARY-CORONARY ARTERY ANASTOMOSIS whereby an occlusion or stenosis of the proximal SUBCLAVIAN ARTERY causes a reversal of the blood flow away from the CORONARY CIRCULATION, through the grafted INTERNAL MAMMARY ARTERY (internal thoracic artery), and back to the distal subclavian distribution.
