Project description:Sinus of Valsalva aneurysm (SoVA) is an uncommon clinical entity, which is present in roughly 0. 09% of the general population. The cause can either be acquired or congenital. Clinically the SoVA of unruptured status are rarely captured or even diagnosed due to atypical clinical presentations. Here, we present a rare case of exertional angina pectoris and recurrent syncope due to an extrinsically compressed left coronary artery by a giant SoVA in a 50-year-old female patient. This SoVA was successfully repaired by the surgical exclusion and the patient was still doing well after 2 years of follow-up.

Project description:Sinus of Valsalva aneurysm (SVA) is a rare cardiac anomaly that can be congenital or acquired. Unruptured aneurysms may be asymptomatic but can present as malignant arrhythmias, acute chest pain, and even sudden cardiac death. Both ruptured and unruptured SVAs may have fatal complications, thus prompt diagnosis and surgery is critical. We report a successful surgical repair of an unruptured aneurysm of the left sinus of Valsalva presenting as acute coronary syndrome. Coronary angiography (CAG) and cardiac multislice computed tomography (CT) revealed a large unruptured aneurysm of the left sinus of Valsalva. Surgical repair was performed by resection of the aneurysm, aortic valve replacement with composite graft, and coronary artery bypass. Aneurysm of the left sinus of Valsalva is an extremely rare condition. Correct diagnosis can be done by echocardiography, CAG, or CT. Non-ruptured aneurysms should be surgically repaired if they are associated with significant symptoms or if their size enlarge rapidly.

Project description:A 70-year-old man was referred to our hospital with a diagnosis of progressive increase in extravasation leading to an iatrogenic coronary artery (CA) pseudoaneurysm within a month of percutaneous coronary intervention (PCI). The pseudoaneurysm was located on the carina side of the proximal left descending artery (LAD) accompanied by peri-stent contrast staining around the left main trunk (LMT). After a shared decision-making process, a second PCI was performed to prevent CA pseudoaneurysm rupture owing to concerns of adhesion around the LMT and difficulty in approaching the carina side of the proximal LAD for surgery. Coil embolization with four coils was performed and kissing stents with two covered stents were implanted. After the "Double-D molding technique," intravascular ultrasound imaging revealed only small residual spaces out of the stents. Final coronary angiography (CAG) revealed no contrast staining of the pseudoaneurysm. Four months after the PCI, follow-up CAG revealed no further pseudoaneurysm enlargement. To the best of our knowledge, this is the first case of PCI for a CA pseudoaneurysm at the LMT bifurcation treated using kissing stents with two covered stents.Learning objectiveCoil embolization and implantation of kissing stents with two covered stents with the "Double-D molding technique" is an optional method to stop further enlargement of the pseudoaneurysm at the left main trunk bifurcation.

Project description:BackgroundCoronary artery embolism is a rare, life-threatening complication in patients with infectious endocarditis. Percutaneous transluminal coronary angioplasty is a common treatment; however, a coronary artery aneurysm may develop at the angioplasty site.Case summaryA 33-year-old women had been hospitalized in another institution due to cardiopulmonary arrest caused by embolic occlusion in the left main artery and infective endocarditis on mitral valve. Following extracorporeal membrane oxygenation insertion, she underwent percutaneous transluminal coronary angioplasty of the left main coronary artery and mitral valve replacement. She was transferred to our institution for advanced heart failure care. We immediately upgraded extracorporeal membrane oxygenation to an extracorporeal left ventricular assist device. Despite 6-week adequate medication, her left ventricular function was not improved. She was listed for heart transplantation on post-operative Day 40. Her blood culture showed negative results for 6 weeks. We planned to convert the left ventricular assist device from extracorporeal to implantable. However, pre-operative coronary artery angiography showed a large left main trunk coronary artery aneurysm on the stent site and rapid aneurysm enlargement. Surgery was performed on post-operative Day 48; the aneurysm was left unresected; its inflow and outflow arteries were completely ligated and supplemented by coronary artery bypass grafting. HeartMate 3 was implanted concomitantly, and the post-operative course was uneventful.DiscussionCoronary artery aneurysm at the angioplasty site was treated with adequate antibiotic therapy and simply ligation of the proximal and distal flow arteries of the aneurysm. Aneurysm ligation reduced invasive surgical procedures and provided time for concomitant surgery.

Project description:BackgroundGiant coronary artery aneurysms are a rare cause of myocardial ischaemia. Due to the rarity and variety of presentation of these cases, no standardized investigation or treatment has been established for management. We report a case study of a giant proximal left anterior descending (LAD) coronary aneurysm causing myocardial ischaemia due to the pressure effect from the weight of the aneurysm as well as from a change in rheology from a 'steal effect' on both the LAD and left circumflex (LCx) arteries.Case summaryA 55-year-old patient presents initially with a history of angina. Initial investigation with computed tomography (CT) was suboptimal, requiring invasive diagnostic angiography, which detects a giant proximal LAD aneurysm. Subsequent investigations, with CT-fractional flow reserve (FFR) and stress echocardiography (ECHO), correlated to identify multi-vessel ischaemia resulting from the aneurysm. The patient was managed with multi-disciplinary team-led surgical resection and triple coronary artery bypass grafts with good results.DiscussionThis case highlights the complexity of coronary anomalies and importance of additional functional three-dimensional imaging on top of the static computational tomography coronary angiography analysis. Together, these two complimentary investigations qualitatively enabled the assessment of anomaly with surrounding structures such that the possibility of a mass effect on the LCx artery results in a positive stress test. Furthermore, this is a novel use of CT-FFR for coronary anomalies and it demonstrated good correlation of LAD territory ischaemia between CT-FFR and the stress ECHO.

Project description:A separation between the aortic media and annulus fibrosus causes a rare cardiac abnormality called sinus of Valsalva aneurysm (SVA) that may be congenital or acquired. It is more prevalent in the right coronary sinus (65%-85%) but it has been seen rarely in non-coronary (10%-30%) or Left coronary sinus (<5%). The most common complication is rupture of the Aneurysm. We present an 80-year-old male with expanding right Valsalva sinus aneurysm and protruding into right ventricle. The conventional treatment is surgical repair under cardio-pulmonary bypass or percutaneous catheter closure. The aneurysm was successfully excised surgically under direct guidance of trans-esophageal echocardiography (TEE).

Project description:Abstract Background Coronary artery aneurysms (CAAs) of the left main represent a small subset of coronary artery disease and are associated with cardiovascular death. Because of its rare entity, large data are lacking and therefore treatment guidelines are missing. Case summary We describe a case of a 56-year-old female with a past medical history of spontaneous dissection of the distal descending left artery (LAD) 6 years before. She presented to our hospital with a non-ST elevation myocardial infarction and a coronary angiogram showed a giant saccular aneurysm of the shaft of the left main coronary artery (LMCA). Given the risk of rupture and distal embolization, the heart team decided to go for a percutaneous approach. Based on a pre-interventional 3D reconstructed CT scan and guided by intravascular ultrasound, the aneurysm was successfully excluded with a 5 mm papyrus-covered stent. At 3-month and 1-year follow-up, the patient is still asymptomatic and repeat angiographies showed full exclusion of the aneurysm and the absence of restenosis in the covered stent. Discussion We describe the successful percutaneous IVUS-guided treatment of a giant LMCA shaft coronary aneurysm with a papyrus-covered stent with an excellent 1-year angiographic follow-up showing no residual filling of the aneurysm and no stent restenosis.
