Abstract: Background: Left ventricular aneurysm is an uncommon but important late mechanical complication of transmural myocardial infarction. Giant aneurysms can cause heart failure, angina, ventricular arrhythmia, thromboembolism, and diagnostic confusion with pseudoaneurysm or mediastinal masses. Case presentation: A 58-year-old male with a history of acute myocardial infarction in 2022 treated abroad by percutaneous coronary intervention/angioplasty with two stents in the left circumflex artery was evaluated for a large left ventricular outpouching. Earlier surgical advice had reportedly been declined, and the patient was managed medically until re-presentation in 2026. Echocardiography showed a large cystic aneurysmal lesion communicating with the posterior left ventricular wall through an approximately 3 cm neck, with left ventricular ejection fraction around 40%, mild left ventricular systolic dysfunction, grade I diastolic dysfunction, mild aortic regurgitation, and mild tricuspid regurgitation with an estimated right ventricular systolic pressure of approximately 36 mmHg. CT cardiac chamber imaging demonstrated cardiomegaly and a giant outpouching arising from the left lateral wall of the left ventricle, measuring approximately 131 x 90 x 115 mm with a 20 mm neck. CT coronary angiography showed mild plaque burden in the LAD, LCx, and RCA, with uncertain distal LCx stent patency. The patient underwent open surgical repair with exclusion of the aneurysmal cavity and ventricular reconstruction with primary multilayer closure of neck using Teflon felt under cardiopulmonary bypass. Conclusion: This case highlights the value of multimodality imaging for defining aneurysm size, neck anatomy, coronary status, and associated thoracic findings. Giant post-infarction aneurysms, especially when large, symptomatic, or anatomically high risk, require individualized heart-team assessment and often surgical reconstruction to restore ventricular geometry and reduce complications.

Abstract: Minimally invasive right mini-thoracotomy is conventionally performed with femoro-femoral cardiopulmonary bypass (CPB) cannulation. Central (aorto-caval) cannulation through the thoracotomy window, though technically demanding, avoids the morbidity associated with femoral access and does not require specialised minimally invasive equipments. Its applicability to combined congenital lesions — particularly atrial septal defect (ASD) with pulmonary stenosis (PS) — has not been widely described. Here we discuss the case of a 20-year-old female presenting with ostium secundum ASD and severe PS. She underwent combined intracardiac repair of ASD with a Dacron patch and relief of PS via pulmonary arteriotomy and right ventricular outflow tract (RVOT) resection through a right mini-thoracotomy approach with conventional central (aorto-caval) cannulation, without femoro-femoral bypass. Aortic cross-clamp time was 38 minutes, cardiopulmonary bypass duration 65 minutes, post-operative extubation at 6 hours, and total drain output 100 mL. There were no procedure-related complications. Post-operative echocardiography confirmed no residual ASD shunt and satisfactory relief of right ventricular outflow obstruction. This report emphasizes that combined ASD repair and PS relief via right mini-thoracotomy with central cannulation is safe, reproducible and technically feasible without dedicated minimally invasive equipment. This approach minimises sternotomy-related morbidity, reduces cost and yields excellent cosmetic results — particularly advantageous in young female patients.
