Insights
Percutaneous closure of left ventricular pseudoaneurysm (LVPA) offers a viable treatment option. A novel direct chest wall entry technique proved successful for LVPA closure, even in challenging cases.
Area of Science:
- Cardiology
- Interventional Cardiology
- Cardiac Surgery
Background:
- Left ventricular pseudoaneurysm (LVPA) is a rare but life-threatening complication following cardiac events or procedures.
- Untreated LVPA carries a high risk of rupture and sudden cardiac death.
- Surgical repair is the traditional treatment, but percutaneous closure is emerging as an alternative for high-risk patients.
Abstract:
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.
