- W1970696498 abstract "Introduction: Myocardial infarction, dilated cardiomyopathy, sarcoidosis, Chaga's disease and myocarditis are recognized causes of left ventricular (LV) aneurysm. Idiopathic LV aneurysms are rare and we describe here one of its rare presentation.Case report description: A 45 year male presented with exertional angina for the past 1 year, with acute exacerbation since one day. His electrocardiogram (ECG) showed ST depression in infero-lateral leads and elevation in lead aVR and V1. Troponin I was negative with cardiomegaly on chest radiograph. Echocardiogram showed enlarged LV with hypokinesia involving antero-lateral wall, LV ejection fraction was 35%. Additionally there was a narrow neck aneurysm arising from the LV outflow tract which was multilobulated and extended anterosuperiorly and laterally causing dynamic compression of right pulmonary artery (RPA). CT angiography also showed similar findings. Coronary angiogram showed severe external compression of left main coronary artery extending up-to mid part of left anterior descending artery and proximal part of left circumflex artery. Surgical aneurysmectomy was done which normalized the LV function on follow up, but residual aneurysm persists requiring a redo surgery.![Figure][1] Figure 1Discussion: Idiopathic LV aneurysm is rare, but well recognized. It usually presents as ventricular tachyarrhythmias or sudden cardiac death. In our patient a giant multilobulated subaortic aneurysm caused extrinsic compression of RPA and left coronary circulation leading to angina. Normalization of LV function at followup suggests relief of external compression of the coronaries.Conclusion: We present here the first case report of a large idiopathic subaortic left ventricular aneurysm causing extrinsic compression of left coronary circulation and RPA manifesting as coronary artery disease.
