Abstract:
A typical feature of mid-ventricular obstructive hypertrophic cardiomyopathy (MVO-HCM), is obvious hypertrophy of the mid-ventricular muscle and ventricle with transformation into the shape of an hourglass. We report a 60-year-old woman who had been given a diagnosis of apical type hypertrophic cardiomyopathy 12 years previously, but it changed to MVO-HCM with apical left ventricular aneurysm. We considered the impending rupture of the aneurysm because its wall was thin and pericardial effusion was detected by UCG (ultrasonic cardiograph). Urgent surgery was performed consisting of ventricular aneurysmectomy and patch reconstruction. After the surgery, a pseudoaneurysm was found in cardiac apex, so we performed surgery again. A residual shunt in the trabeculation caused the pseudoaneurysm, but its origin was not clear. She has been fine for 18 months without complications such as recurrence of aneurysm, ventricular arrhythmia or left ventricular dysfunction since the last surgery.
