Off-pump surgery for giant right coronary artery aneurysms.

ABSTRACT: 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.

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.

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 coronary artery aneurysms involving all three coronary arteries.

Project description:Coronary artery aneurysm is defined as any coronary artery dilation exceeding the diameter of normal adjacent segments or the diameter of the largest coronary artery by 1.5 times. Giant coronary aneurysm refers to an aneurysm with a diameter larger than 20 mm. Giant coronary artery aneurysms have an incidence of 0.02%-2%. Here we describe a patient who had giant coronary aneurysms involving all three coronary arteries. He was managed conservatively with no cardiac events on a follow up of 1 year.

Delineating anatomy and function with multimodality imaging: a case report of giant right coronary artery aneurysms.

Project description:Background:Giant coronary artery aneurysms (CAAs) are rare and have been reported in patients with connective tissue diseases, arteritides, and atherosclerosis. Given the rarity of the condition, multimodality imaging is essential for comprehensive evaluation of coronary aneurysms and determination of their haemodynamic significance. Case summary:A 58-year-old Filipino female was evaluated for dyspnoea on exertion of one month. Chest computed tomography (CT) showed right coronary artery (RCA) aneurysms. Invasive coronary angiogram (ICA) confirmed two giant aneurysms of the RCA. Distal RCA could not be opacified due to contrast stagnation in the proximal aneurysms. Coronary CT angiography (CCTA) depicted an additional giant distal RCA aneurysm not visualized on ICA with intraluminal thrombosis. Contrast-enhanced cardiac magnetic resonance imaging (CMR) revealed delayed time to peak perfusion in the mid to apical inferior walls, on first-pass imaging, without myocardial scarring. Late gadolinium images revealed aneurysmal wall inflammation. Discussion:This case highlights the anatomical findings of giant CAA and the application of multimodality imaging for their accurate characterization. While ICA confirmed the presence of the aneurysms, CCTA enabled the assessment of their full extent and depict intraluminal thrombosis. Contrast-enhanced CMR delineated aneurysm wall characteristics, with first-pass images demonstrating reduced inferior wall perfusion at rest, which was likely the cause of patient's exertional symptoms. Management of giant coronary aneurysms involves surgical resection with bypass grafting.

Giant coronary artery aneurysms in a 58-year-old.

Project description:All giant Kawasaki aneurysms may not regress fully; some may eventually calcify, undergo thrombosis, and get detected in asymptomatic adults at later age. Tomisaku Kawasaki initially described this illness as mucocutaneous lymph node syndrome in childhood in 1967 and coronary arteritis was recognized later. We present a 58-year-old male, possibly one of the oldest surviving patients with giant coronary aneurysms who presented with large secundum atrial septal defect (ASD) with heart failure. This indicates that the disease was perhaps prevalent outside Japan even before the first Kawasaki's description.

Remote ischemic preconditioning in on-pump coronary artery bypass graft surgery

Project description:In this placebo-controlled randomized controlled trial, we tested whether remote ischemic preconditioning (RIPC) elicited by four 5-minute cycles of 300 mmHg of cuff inflation/deflation of the lower limb would reduce myocardial necrosis in isoflurane-anesthetized patients undergoing on-pump coronary artery bypass graft surgery. Secondary outcomes were the perioperative release of the biomarkers NTproBNP, hsCRP, S100, atrial transcriptional profiles, and short- and long-term clinical outcomes. RIPC with concomitantly applied isoflurane did not affect the release of biomarkers or clinical outcome. NTproBNP release correlated with isoflurane- but not RIPC-induced transcriptional changes. For eleven randomly selected patients from each group (RIPC/CTL=no RIPC) two atrial samples were collected, one at the time of cannulation (T1) and one fifteen min after releasing the cross clamp (T2). The samples were immediately frozen in liquid nitrogen and later used for RNA isolation and subsequent microarray hybridization. Gene-level analysis was performed. the results of exon-level analysis will be published separately (only preliminary results available so far).

Unusual Case of Giant Nonthrombosed Right Coronary Artery Pseudoaneurysm With Coronary Artery Fistula.

Project description:Coronary artery aneurysm and pseudoaneurysm are rare and mainly result from atherosclerosis. We present a successfully treated case of a giant right coronary artery aneurysm and pseudoaneurysm with a coronary artery fistula, which might have developed after cardiac surgery for a right ventricular tumor 35 years earlier. (Level of Difficulty: Advanced.).
