Coronary artery bypass grafts: improved electron-beam tomography by prolonging breath holds with preoxygenation.
نویسندگان
چکیده
In 45 patients with coronary bypass grafts, the breath-hold interval with and that without preoxygenation was measured. Its effect on depiction of the distal graft anastomosis at electron-beam tomography was evaluated. Preoxygenation prolonged the breath-hold interval in most patients, thereby allowing greater anatomic coverage including more distal anastomoses. Preoxygenation may improve scanning of coronary bypass grafts and increase detectability of graft stenoses.

Coronary artery fly-through using electron beam computed tomography.
BACKGROUND Virtual reality techniques have recently been introduced into clinical medicine. This study examines the possibility of coronary artery fly-through using a dataset obtained by noninvasive coronary angiography with contrast-enhanced electron-beam computed tomography. METHODS AND RESULTS Ten patients were examined, and 40 to 60 transaxial tomograms (thickness, 1.5 mm; in-plane pixel ...

This 33-year-old patient had had emergency surgery 11 years earlier, at age 22 years, for acute dissection of the ascending aorta involving the main stem of the left coronary artery with grade 4 regurgitation of the aortic valve. The aortic valve and the ascending aorta were replaced with a conduit consisting of a biological prosthetic aortic valve and an aortic prosthesis (Bentall’s technique)...

Recently, noninvasive imaging modalities such as electron-beam computed tomography, magnetic resonance angiography, and single-slice helical computed tomography (CT) have emerged as ways to visualize the coronary arteries. With regard to internal mammary artery grafts, however, conventional 3D imaging techniques have failed to demonstrate consistently satisfactory performance. We overcame these...

A70-year-old man with exertional angina presented for cardiac catheterization. The past medical history was significant for coronary artery bypass graft surgery in 1984 with placement of a left internal mammary artery (LIMA) graft to the left anterior descending coronary artery and a single saphenous vein graft, sequentially, to 2 obtuse marginal vessels and the posterior descending coronary ar...
متن کاملPrediction of Changes in Left Ventricular Ejection Fraction after Off-Pump Coronary Artery Bypass Grafting Surgery by Myocardial Perfusion Single-Photon Emission Computed Tomography
Introduction: Left ventricular ejection fraction (LVEF) is considered to be the single most important prognostic factor in patients with previous myocardial infarction. LVEF is not improved in all patients after coronary artery bypass grafting (CABG). This study aimed to assess the possibility of prediction of LVEF changes after CABG using myocardial perfusion gated signle photon emission compu...
