Cardiac imaging in prosthetic paravalvular leaks

Area of Science:

• Cardiology
• Medical Imaging
• Interventional Cardiology

Background:

• Prosthetic paravalvular leaks (PVL) are a rare but significant complication following surgical valve replacement.
• Hemodynamically significant PVL traditionally necessitates surgical intervention.
• Percutaneous transcatheter closure is an emerging, less invasive alternative for high-risk patients.

Purpose of the Study:

• To review the critical role of cardiac imaging in the interventional management of symptomatic prosthetic paravalvular leaks.
• To highlight the diagnostic and guidance capabilities of imaging modalities in PVL treatment.
• To discuss the evaluation of outcomes post-intervention using cardiac imaging.

Main Methods:

• Review of current literature and clinical practices.
• Emphasis on the application of two- and three-dimensional transoesophageal echocardiography (TEE).
• Discussion of imaging guidance during transcatheter PVL closure.

Main Results:

• Cardiac imaging is indispensable for accurate PVL diagnosis.
• Transoesophageal echocardiography (TEE) is vital for guiding percutaneous closure procedures.
• Imaging facilitates comprehensive post-procedural outcome assessment.

Conclusions:

• Cardiac imaging, particularly TEE, is essential throughout the interventional management of symptomatic PVL.
• Transcatheter closure, guided by imaging, offers a viable alternative to surgery for high-risk patients.
• Accurate imaging ensures effective intervention and evaluation of PVL treatment outcomes.
