Abstract:
Left ventricular (LV) apical aneurysm associated with aortic valve stenosis (AS) is very rare. We herein report two cases of this entity. Case presentation Case 1 was a 75-year-old woman admitted for surgery for severe AS and enlargement of the ascending aorta. Preoperative routine echocardiography and cardiac computed tomography (CT) revealed an unexpected local aneurysm of the LV apex. The patient underwent aortic valve replacement (AVR), LV aneurysm resection, and ascending aorta replacement. Case 2 was a 71-year-old woman diagnosed with severe AS. Preoperative cardiac CT detected LV apical aneurysm that could not be detected by echocardiography. Cardiac catheterization showed a coronary ventricular fistula. The patient underwent AVR and LV aneurysm resection. Given that neither of the two cases had a history of myocardial infarction or obstructive hypertrophic cardiomyopathy, the cause of the local aneurysm of the LV apex was thought to be relative ischemia at the apex due to myocardial hypertrophy and LV pressure overload due to long-term AS. In addition, a coronary artery fistula was suggested to be involved in the relative ischemia of the apex in Case 2. Conclusions Echocardiography alone is not sufficient to exclude apical aneurysm, and cardiac CT may be useful. Regarding the surgical indication, it is necessary to consider further cases in the future.
