Surgery for a giant atherosclerotic left main trifurcation saccular coronary artery aneurysm.

Aneurysms of the left main coronary artery are rare clinical entities with an incidence of 0.1%. We herein report a case of left main trifurcation aneurysm in a 57-year-old woman whose coronary angiography demonstrated a giant saccular aneurysm of trifurcation of the left main coronary artery, measuring 32 × 21mm with tight post-aneurysmal stenosis in the intermediate artery. The patient underwent coronary artery bypass grafting following the resection of CAA and reconstruction with saphenous vein roof-plasty, which ensured the preservation of the native coronary vasculature. At the 6-month follow-up, she remained asymptomatic and preserved preoperative left ventricular function.

Coronary Involvement of Behçet's Disease: Saccular Coronary Artery Aneurysm.

Coronary artery aneurysms (CAAs) are rarely reported in large angiographic series. The majority are atherosclerotic in origin. Other causes are connective tissue disorders, trauma, vasculitis, congenital, mycotic, and idiopathic. We herein present the case of an symptomatic patient with a giant left anterior descending artery aneurysm. The CAA was successfully treated by surgical resection and a mammary artery bypass graft.

Surgical exclusion of an idiopathic saccular aneurysm in the left main trunk of the coronary artery

PurposeA coronary artery aneurysm (CAA) can result in critical cardiac events such as thromboembolic complications or rupture. A saccular CAA located in the left main trunk (LMT) is the most critical form of this pathology and its surgical repair is challenging. We conducted this single-center study to review the surgical outcomes of patients with a saccular CAA in the LMT.MethodsBetween May, 2012 and June, 2020, five patients with a saccular CAA in the LMT underwent surgery at our center. The median age at operation was 66.5 (59.7–69) years and the median diameter of the CAA was 13.0 mm (IQR 11–14 mm).ResultsThe CAA was fully excluded by patch closure of the LMT orifice and direct closure of the distal LMT, supplemented by coronary artery bypass grafting with the exclusive use of arterial conduits. There was no in-hospital mortality, although one patient suffered graft spasm-related myocardial infarction with complete recovery. Post-operative angiography showed a fully excluded LMT in all patients. There was no mortality or adverse cardiac events during follow-up.ConclusionsOur surgical policy for CAA in the LMT is feasible and safe; however, coronary blood flow is dependent on reliable bypasses.

Patent Coronary Artery 23 Years After Direct Closure of Coronary Artery Aneurysm

59-year-old woman was referred to us for heart Amurmur. Coronary angiography (Fig 1) showed that there was a huge saccular coronary artery aneurysm at the proximal left anterior descending artery (LAD) and abnormal vessels rising from coronary branches to pulmonary artery. The operation was performed through a median sternotomy. Cardiopulmonary bypass was established, and cardioplegic solution was infused antegrade after aortic cross clamping. The aneurysm was located at the proximal LAD. The aneurysm was opened longitudinally, and there were proximal and distal orifices of LAD at the base of the aneurysm. In addition, the intimal wall of the LAD was intact. We directly closed the LAD using several stiches using the circumferential aneurysmal wall (Fig 1). The aneurysmal wall was left open. Fistulas were ligated. Postoperative course was uneventful.

Saccular Coronary Artery Aneurysm and Fistula with Organized Thrombi

Saccular coronary artery aneurysm, associated with coronary artery fistula, is a very rare condition. A 48-year-old woman was referred to our hospital for the evaluation of an abnormal shadow on the left cardiac border from a chest X-ray film during regular medical health examination. A huge saccular aneurysm with organized thrombi in the proximal left anterior descending artery (LAD) and coronary artery fistulae from LAD and conus branch of the right coronary artery to pulmonary artery was diagnosed by transthoracic echocardiography, multi-detector computer tomography (MDCT), and coronary angiography. The patient received surgical treatment, including thrombectomy of aneurysm, ligation of the inlet and outlet of aneurysmal sac, coronary artery bypass graft (left internal mammary artery-to-distal LAD), and ligation of fistulae. The postoperative course was uneventful, and postoperative echocardiography and MDCT revealed patent bypass graft; however, a small fistula from proximal LAD across aneurysmal sac to pulmonary artery was observed.

Surgical treatment of giant saccular coronary artery aneurysm: a case report

Aneurysm of coronary arteries is rare and diagnosis is usually made accidentally during coronary angiography. Atherosclerosis, Kawasaki disease, autoimmune diseases and syphilis are among common etiologic factors. Spontaneous rupture of the aneurysmal sac, thrombosis and distal emboli are the major causes for mortality and morbidity. Treatment options vary from surgical intervention to conservative drug therapy such as antithrombotic treatment, depending on the localization and the dimensions of the lesion and the clinical outcome of the patient. In this article, we report a patient who underwent operation for giant saccular coronary artery aneurysm in the left anterior descending artery.

Successful Management of a Posterior Saccular Coronary Artery Aneurysm at the Left Main Coronary Artery Bifurcation

Left main coronary artery aneurysm is a rare condition that presents as a potential surgical challenge due to its location. We present a case of successful repair of a posterior saccular aneurysm of the left main coronary artery by aneurysm exclusion, afferent and efferent ligation with coronary artery bypass grafting.

Resection and Patch Repair of a Large Saccular Coronary Artery Aneurysm at the Left Main Bifurcation

Coronary artery aneurysm is a rare condition with primarily conservative treatment. Here, we present a case of saccular left main coronary aneurysm with a successful patch repair and discuss the indications for operative treatment.
