Left ventricular pseudoaneurysm as a complication of electrophysiologic study
1Division of Cardiology, Department of Medicine, Loma Linda University Medical Center, California 92354, USA.
Summary
A small pseudoaneurysm of the left ventricle developed in a patient undergoing electrophysiologic mapping for a concealed accessory pathway. This lesion, detected via echocardiography, healed spontaneously within one month.
Area of Science:
- Cardiology
- Cardiac Electrophysiology
- Medical Imaging
Background:
- Electrophysiologic mapping is a key diagnostic tool for arrhythmias.
- Concealed accessory pathways can cause supraventricular tachycardia.
- Left ventricular pseudoaneurysms are rare but serious cardiac complications.
Observation:
- A patient developed a small submitral pseudoaneurysm of the left ventricle during electrophysiologic mapping.
- The pseudoaneurysm was incidentally detected on a routine postprocedure echocardiographic study.
- The patient remained asymptomatic throughout the observation period.
Findings:
- The submitral pseudoaneurysm demonstrated spontaneous healing.
- Echocardiography confirmed the resolution of the lesion one month post-procedure.
- No intervention was required for the pseudoaneurysm.
Implications:
- This case highlights the potential for rare complications during electrophysiologic procedures.
- Spontaneous resolution of submitral pseudoaneurysms is possible.
- Routine echocardiographic follow-up can aid in detecting and monitoring such lesions.
