Flow dynamics of angiographically no-flow patent internal mammary artery grafts.
OBJECTIVES This study sought to assess the flow dynamics of internal mammary artery grafts (IMAGs) in no-flow situations by use of a Doppler guide wire. BACKGROUND Functionally no-flow and anatomically patent IMAGs have been reported by angiography in patients with a patent recipient coronary artery. METHODS The study included 12 patients with an IMAG to the left anterior descending coronar...
متن کاملComparison of blood-flow velocity waveforms in different coronary artery bypass grafts. Sequential saphenous vein grafts and internal mammary artery grafts.
Characteristics of blood-flow velocities were investigated at different sites in two types of coronary artery bypass grafts, sequential saphenous vein grafts (SSVG) and internal mammary artery grafts (IMAG). The latter appear to have the longest life span. The patency rate of the side-to-side anastomosis of the SSVG is better than that of the end-to-side anastomosis. The SSVG was anastomosed to...
متن کاملAortic valve replacement by ministernotomy in redo patients with previous left internal mammary artery patent grafts.
OBJECTIVE Aortic valve surgery with a patent left internal mammary artery (LIMA) on the left anterior descending (LAD) coronary artery is challenging in terms of myocardial protection and graft injury. Minimally invasive techniques may require minimal dissection of adhesions and may eventually decrease the risk of injuries. METHODS Since 1997, more than 1000 ministernotomies have been perform...

متن کاملPercutaneous transluminal angioplasty of left internal mammary artery grafts.
stenoses or distal native coronary artery stenoses and angina pectoris. The procedure was technically successful in 10 patients and no major complications occurred. During follow up there was one late death, but all 10 surviving patients showed functional improvement. Percutaneous transluminal angioplasty seems to be a safe and effective treatment for stenoses of internal mammary artery grafts....
