Position dependent right ventricular dysfunction caused by a giant right coronary artery aneurysm

Giant Right Coronary Artery Aneurysm in a Patient With Multiple Coronary Artery Aneurysmatic Dilatations

One kind of coronary artery disease that is uncommon is coronary artery aneurysm (CAA). According to angiographic reports, the incidence of coronary artery aneurysms ranges from 1.5% to 4.9%, with a higher frequency in men. A patient with both coronary heart disease and an aneurysm in the right coronary artery (RCA) underwent a successful simultaneous coronary bypass together with an aneurysmal reconstruction procedure.

Multiple and giant coronary artery aneurysm - case report and a review of the literature

We report an unusual case of a 70-year-old female patient admitted in the Department of Cardiology, Emergency County Hospital, Oradea, Romania, for unstable angina and heart failure. Coronary angiography and computed tomography revealed multiple coronary artery aneurysms, some of them giant, associated with significant coronary artery disease. Coronary artery aneurysm is a rare disease, but the frequency of diagnostic increased with the development of coronary angiography. However, very rarely coronary artery aneurysm is very large and can be termed “giant aneurysm”, and a small number of reports have been described in literature. The management and the prognosis of the disease is still controversial.

•

Coronary artery aneurysm is a possible differential diagnosis for chest pain.

•

Echocardiography allows bedside detection of coronary artery aneurysm.

•

Cardiac CT permits detailed assessment of a coronary artery aneurysm.

A case of early development of giant coronary artery aneurysms after drug-eluting stents implantation: An unpredictable menace

Development of coronary artery aneurysm (CAA) after implantation of drug-eluting stent is occasionally observed. We present a case of a 67-year-old man who underwent everolimus-eluting stent (EES) implantation in right coronary artery (RCA) for inferior wall myocardial infarction, and thereafter, giant CAAs were developed in the vessel of stent deployment, within 2 months. However, the patient was managed with coronary artery bypass grafting (CABG). On follow-up, the patient's condition was stable. To the best of our knowledge, we report the first case of occurrence of EES-associated giant CAAs in RCA subsequently treated with CABG.

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

INTRODUCTION

Coronary 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 RESULTS

A 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.

CONCLUSIONS

Coronary 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.

Spontaneous coronary artery dissection: case report and review of literature

Spontaneous coronary artery dissection (SCAD) is an unusual cause of acute coronary syndrome or sudden cardiac death. SCAD has most frequently been described as presenting as an acute coronary syndrome in females during the peripartum period. It may also be associated with autoimmune and collagen vascular diseases, Marfan's syndrome, chest trauma, and intense physical exercise. The most common presentation of SCAD is the acute onset of severe chest pain associated with autonomic symptoms. This condition has a high mortality rate if not identified and treated promptly. Here, we present a case of SCAD presenting with stroke, followed by a brief review.

A case of giant coronary artery aneurysm with fistulous connection to the pulmonary artery: a case report and review of the literature

Giant coronary artery aneurysm is a rare condition with a reported prevalence of 0.02%. Herein, we report the case of a 79-year-old woman with a giant coronary aneurysm arising from a branch of the left anterior descending coronary artery that had a fistulous connection to the pulmonary artery. The aneurysm was removed and inflow and outflow arteries were closed surgically. Histology showed prominent mucinous degeneration and infiltration of inflammatory cells in the medial layer. After successful surgery, the patient was discharged uneventfully.
