Pressure-flow measurements were obtained from the vein graft of 57 patients undergoing a single aorta-to-coronary bypass procedure. The flow contour was similar to phasic left coronary artery flow in dogs except for a transient increase during systole possibly related to elongation of the graft. Flow was highest during bypass and decreased to a stable value 30 min after bypass. In 42 patients, ...

With the proliferation of minimally invasive cardiac surgery a number of alternative inflow sites for coronary artery bypass grafting have been utilized, especially in higher risk patients. The use of axillary-coronary artery bypass is a safe and effective alternative especially in the case of patients requiring redo coronary revascularization. However, the length and convoluted course of the a...

HYPOTHESIS Comorbid conditions are associated with the risk of death from coronary artery bypass graft surgery. DESIGN Prospective cohort study data were collected on patient and disease characteristics and comorbid conditions including hypertension, diabetes, obesity, vascular disease, chronic obstructive pulmonary disease, cancer (excluding nonmelanoma skin cancer), dialysis-dependent renal...

A 57-year-old male visited our clinic with chief complaint of exertional chest pain. He had been on anti-hypertensive medication for 15 years. In 1999, he went through coronary artery bypass graft surgery for myocardial infarction, using an aorto-left anterior descending artery (LAD) bypass with the left internal mammary artery, and aorto-right coronary artery (RCA) bypass with saphenous vein. ...

right ventricular failure due to right coronary artery disease, right ventricular hypertrophy, stunning, abnormal septal motion, myocardial infarction, or non-homogeneous distribution of cardioplegia is an uncommon but serious complication of open heart surgery. we report a patient with severe right ventricular hypertrophy secondary to severe mitral valve stenosis and another patient with detac...

reliable, exclusively in appropriately selected situations. In creation of bypass grafts, durable completeness of revascularization and function of the ITA to the LAD bypass should not be compromised. We would suggest that the balanced bypass flow toward the LAD and the RCA is noticeably important to achieve an entire patency of the Y-graft for three-vessel regions. This study is not conclusive...

in patients requiring coronary artery bypass grafting (cabg), usually at least one of the internal mammary arteries is used. this study evaluates the degree of atherosclerotic involvement of the internal mammary artery (ima) in patients undergoing cabg. during two months period, 79 patients (66 male and 13 female with a medium age of 58 years) undergoing myocardial revascularization had a biops...

BACKGROUND During coronary anastomosis in off-pump coronary artery bypass surgery (OPCAB), hemodynamic alternations can be induced by impaired diastolic function of the right ventricle. This study was designed to examine the effect of milrinone on right ventricular function and early outcomes in patients undergoing OPCAB. METHODS Forty patients undergoing OPCAB were randomly assigned in a dou...

A23-year-old man who had had cardiac murmurs since childhood experienced heart arrest during exercise. Cardiac resuscitation and cardioversion of ventricular fibrillation rescued the patient. Subsequent work-up showed that the patient’s left coronary artery arose from the main pulmonary artery. Transesophageal echocardiography showed aneurysmal dilatation of the left coronary artery, which aros...
