Why the study?
Hypertrophic cardiomyopathy with apical aneurysm carries a high risk of sudden cardiac death from ventricular arrhythmias and thromboembolism.
Surgical resection combined with cryoablation may be an effective treatment for midventricular hypertrophic obstructive cardiomyopathy with an apical aneurysm to prevent sudden death and thromboembolism.
Surgical myectomy plus cryoablation may be feasible for apical aneurysm in mid-cavity obstructive HCM with thrombus; leaves open need for prospective data.
