Pacemaker Treatment for Apical Hypertrophic Cardiomyopathy in the Setting of an Apical Ventricular Aneurysm.

We describe the case of a patient with apical hypertrophic cardiomyopathy with concomitant apical aneurysm. We measured the aneurysmal cavity pressure using the pressure guidewire system. The patient underwent implantable cardioverter-defibrillator treatment successfully to reduce the pressure gradient between the aneurysmal cavity and the true left ventricle. (Level of Difficulty: Intermediate.).
