چکیده
Isolated critical ostial stenosis of left main coronary artery is currently treated by conventional bypass surgery. Surgical patch angioplasty in an alternative surgical approach. Transesophageal echocardiography enables visualization of proximal branches of left and right coronary artery. The report describes intraoperative echocardiographic assessment of surgical left main coronary artery angioplasty.

Surgical reconstruction of the left main coronary artery with patch-angioplasty
BACKGROUND Conventional coronary artery bypass grafting (CABG) has been established as the treatment of choice for left main coronary artery (LMCA) stenosis However, the conventional grafting provides a retrograde perfusion to extensive myocardial area and leads prospectively to competitive flow of the non-occluded coronaries thus consuming the grafts. Surgical reconstruction of the LMCA with p...
متن کاملSurgical Patch Angioplasty of the Left Main Coronary Artery and/or the Proximal Segment of the Right Coronary Artery
Surgical patch angioplasty is procedure for lesions of the main coronary arteries but it is not performed frequently because of technical complexity and uncertainty about final results. We present experience of SPA for treatment of main coronary artery lesions and assess medium-term outcomes after this procedure. Since November 1998 13 patients have undergone SPA. There was an isolated left/rig...
متن کاملExtensive patch angioplasty of the left main ostial stenosis using a rhombic-shaped pulmonary autograft.
A rhombic shaped pulmonary autograft patch was applied to enlarge an ostial stenosis of the left main coronary artery (LMCA) in a 25-year-old woman diagnosed with vasculitis syndrome. The patch increased the width of the ostial stenosis and made a funnel-shaped connection. At eighteen months of follow-up, a coronary angiogram by computed tomography showed no restenosis at the LMCA. The rhombic-...
متن کاملSurgical patch angioplasty of the left main coronary artery.
Isolated ostial stenosis of the left main coronary artery (LMCA) is rare, occurring in <1% of the patients undergoing coronary angiography. Surgical patch angioplasty (SPA) offers an alternative to conventional coronary artery bypass grafting (CABG) in such cases and is advantageous in restoring more physiological myocardial perfusion, maintaining ostial patency and preserving conduit material....

OBJECTIVE The objective of this study was to retrospectively analyze the clinical course and postoperative long-term survival of patients diagnosed with isolated left main coronary artery (LMCA) stenosis after surgical revascularization. METHODS A total of 38 patients (27 males, 11 females) who were diagnosed with isolated LMCA stenosis and underwent surgical revascularization were enrolled i...
