Mid ventricular systole
WebIt is most often associated with congenital perimembranous ventricular septal defects, but can also be caused by increased atrial and ventricular pressure, endocarditis, or can occur after a transmural septal myocardial infarct. 9 Echocardiographically, an aneurysm is characterized by myocardial thinning with dyskinetic motion toward the RV during systole. WebCoronary angiogram showed normal coronaries, and her left ventriculogram showed mid cavitary obliteration in systole with aneurysm of the apex ( Figures 2 and 3 ). A cardiac MRI was performed which confirmed the diagnosis of mid-cavity hypertrophic obstructive cardiomyopathy with an apical aneurysm.
