Novel approach for the percutaneous treatment of left ventricular pseudoaneurysms.

Left ventricular pseudoaneurysm (LVPA) is a rare yet serious complication that may follow cardiac surgery, myocardial infarction, trauma, or infection. If left untreated, reported rates of rupture and sudden cardiac death are high. Although surgical intervention has traditionally been the standard treatment for LVPA, percutaneous closure is now an attractive alternative in the high-risk patient. We report a case of a successful percutaneous LVPA closure using direct chest wall entry into the pseudoaneurysm. This novel approach can be useful when access to the LVPA is a challenge, especially in the setting of small ostial size, dense left ventricular trabeculations, angulated serpiginous tract, and presence of mechanical prostheses.
