Project description:Coronary artery aneurysms larger than 5 cm are exceedingly rare, and a standard treatment for them is lacking. We report two cases of giant right coronary artery aneurysms successfully treated by off-pump resection of the aneurysm and bypass grafting. The controversy surrounding the proper management of such cases is discussed.

Giant Right Coronary Artery Aneurysm Detected by Transthoracic Echocardiography.

Project description:Coronary artery aneurysms (CAAs) are rare findings caused by atherosclerosis in about 50% of cases. They are usually diagnosed using coronary angiography, cardiac computed tomography, or magnetic resonance imaging. In this report, we present a rare case of giant, isolated right CAA, detected by transthoracic echocardiography in an adult patient with unstable angina. Diameters of the aneurysm were 3.6 cm × 2.7 cm. Anterior-septal hypokinesia of the left ventricle was also noted. A comprehensive echocardiographic examination, including contrast study, excluded alternative diagnoses and supported the hypothesis of a coronary ectasia. The coronary angiography confirmed the diagnosis of giant coronary aneurysm and revealed a severe three-vessel disease. The patient was treated with cardiac surgery a few days later: two coronary artery bypass grafts and exclusion of the aneurysm by surgical legation were successfully performed.

Multiple giant coronary artery aneurysms combined with right coronary artery-pulmonary artery fistula: a case report.

Project description:BACKGROUND:The combination of multiple giant coronary artery aneurysms (CAAs) and right coronary artery (RCA) to pulmonary artery (PA) fistula is extremely rare and the patients with CAAs may suffer from several fatal complications. We herein describe a 60-year-old female with hemodynamic instability who was diagnosed with multiple giant CAAs combined with RCA-PA fistula. CASE PRESENTATION:The patient, a 60-year-old female, presented to the emergency room because of progressive exertional chest distress and fatigue. The transthoracic echocardiography (TTE), coronary computed tomography angiography (CTA) and invasive coronary angiography confirmed the existence of multiple giant CAAs and RCA-PA fistula. Laboratory examinations for systemic vasculitis and infectious diseases demonstrated no abnormalities and work-up for childhood and family history were negative. We have performed a successful surgical treatment for this patient. The patient's restrictive cardiac dysfunction was improved after debriding the advanced thrombi in aneurysm sac and ligating the fistulous vessel between the native RCA and PA. The postoperative pathologic examination of the aneurysmal wall revealed loss of smooth muscle cells in the media with local mucoid degeneration, no chronic inflammation, sclerosis and IgG4 were observed. CONCLUSIONS:The treatment decision-making process should depend upon the patients' specific situations. Our case suggests the surgical intervention should be accepted as the preferred treatment for giant CAAs with restrictive cardiac dysfunction.

Surgical repair of an asymptomatic giant right coronary artery aneurysm.

Project description:Background Coronary artery aneurysm (CAA) is a rare finding, being mostly diagnosed on angiography or at autopsies. It is defined as being a dilation of the coronary artery that exceeds the diameter of the patient's largest coronary vessel by 1.5 to 2 times. Case Report We describe the operative correction of a giant right CAA measuring in excess of 10 cm. Conclusion Management of giant CAAs is not standardized and surgical strategy remains controversial. In our case, the patient has a successful surgical repair with no postoperative shunts on follow-up investigations.

Giant right coronary artery aneurysms presenting as a cardiac mass: Case report.

Project description:IntroductionCoronary artery aneurysm (CAA) is defined as coronary dilatation which exceeds the diameter of the normal adjacent artery segments or the diameter of the patient's largest coronary artery by 1.5 times. The incidence of giant CAA is difficult to be determined, since only few reports have been described in the literature.Methods and resultsA 65-year-old man was referred to our hospital because of a "mass" in the right heart detected on echocardiography at a regular medical health examination, while he experienced no any symptoms. Coronary angiography showed the severe stenosis of the left anterior descending artery (LAD) and the left circumflex artery (LCX) and the diffusely ectatic change of the right coronary artery (RCA), but no mass was found in any of these arteries. Coronary computed tomography angiography (CTA) confirmed that the "mass" was the giant aneurysms of RCA with thrombus. He received coronary artery bypass graft (CABG) with thrombectomy. The histopathology showed the deposits of lipid and hyalin in the tunica intima, the focal calcifications, the very thin tunica media, and the disappearance of the part of the tunica media in the RCA.ConclusionsCoronary artery aneurysm which may contain thrombus can complicate a diagnostic coronary angiography due to the risk of distal embolization and may lead to myocardial infarction. This case report demonstrates 2 RCA aneurysms with a thrombus presenting as a giant "mass" which was successfully treated by CABG with thrombectomy.

Giant Aneurysm of the Right Coronary Artery: Multimodality Imaging and Interventional Management.

Project description:A large (40-mm) circular structure in the right atrioventricular groove was detected by transthoracic echocardiography and was diagnosed as a giant aneurysm of the right coronary artery. Through invasive mapping by a guide extension catheter, the aneurysm could be excluded by implantation of 3 overlapping stent grafts. (Level of Difficulty: Beginner.).
