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

ABSTRACT: 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.).

Case report: Multimodality imaging revealing ruptured giant coronary artery aneurysm presenting with hemoptysis.

Project description:Giant coronary artery aneurysm (CAA) is a relatively uncommon disease that is defined by a focal dilation of at least 20 mm and characterized by various clinical symptoms. However, cases presenting primarily with hemoptysis have not been reported. A man in his late 20 s suffering from persistent chest pain for over 2 months was transferred to our emergency department for intermittent hemoptysis lasting for 12 h. Bronchoscopy detected fresh blood in the left upper lobe bronchus without a definite bleeding source. Magnetic resonance imaging (MRI) demonstrated a heterogeneous mass and the high-intensity signals suggested active bleeding. coronary computed tomography (CT) angiography demonstrated a giant ruptured CAA wrapped in a large mediastinal mass Coronary angiography confirmed the CAA originating from the left anterior descending artery. The patient underwent an emergency sternotomy and an enormous hematoma arising from a ruptured CAA densely adhering to the left lung was identified. The patient recovered uneventfully and was discharged on the 7th day later. The ruptured CAA masquerading as hemoptysis highlights the indispensability of multimodality imaging for accurate diagnosis. Urgent surgical intervention is desirable in such life-threatening conditions.

Surgical management of a giant right coronary artery aneurysm with coronary arteriovenous fistula: case report.

Project description:BackgroundCoronary artery aneurysms (CAAs) are uncommon, and giant aneurysms (>2 cm) are even more unusual. Coronary atherosclerosis and Kawasaki disease are the leading causes for this pathology. The treatment for this condition is controversial because the evidence is based on case report series.Case summaryWe describe the case of a 77-year-old female patient who presented with heart failure symptoms. She was diagnosed with a giant saccular aneurysm arising from the right coronary artery (RCA) ostium and a fistula between the RC and the left anterior descending artery (LAD) to the coronary sinus. And an atrial septal defect (ASD) and severe tricuspid regurgitation were also found. The patient underwent surgery through a medium sternotomy, the aneurysm was opened and resected under cardiopulmonary bypass. The RCA was ligated at the distal end of the aneurysm, and a saphenous vein graft bypass was performed. A coronary arteriovenous fistula from the distal portion of RC and LAD artery to a severely enlarged coronary sinus was found and corrected with an autologous pericardial patch. Closure of the ASD was performed with a pericardial patch and a tricuspid ring annuloplasty was done. Post-operative course was uneventful.DiscussionThere are few cases of giant coronary aneurysms associated with fistulas reported in the literature. Despite the endovascular percutaneous techniques available to treat these patients, we believe that surgical treatment was the best option for this particular case. We consider that surgical treatment is a very good option for giant CAAs associated with AV fistulas that are not susceptible for current endovascular available devices. The literature lacks evidence regarding the best approach for these cases, and we think that invasive treatment should be tailored according to the heart's anatomy and patient risk.

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.

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.

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.
