Introduction/Statement of Need: Hemodynamics of percutaneous valves have been very favorable. However, a challenging area has been the new or residual valve regurgitation that may occur either after transcatheter valve implantation or repair of a native or prosthetic valve. This condition presents a diagnostic and therapeutic challenge to the interventional and imaging cardiology team in the catheterization laboratory and to the clinician and imager in the outpatient setting. The current document addresses the challenges of assessing residual regurgitation after percutaneous valve replacement or repair and provides a guide to the cardiac team on how best to approach this condition, based on the available data and a consensus of a panel of experts.
Target Audience: This activity is designed for all cardiac sonographers and cardiovascular physicians with a primary interest and knowledge base in the field of echocardiography; in addition, residents, researchers, clinicians, intensivists, and other medical professionals.
Learning Objectives: At the end of this article the reader will better be able to:
Describe the various echo-Doppler methods for intra-operative monitoring during transcatheter aortic valve replacement and transcatheter mitral valve repair
Enumerate the various methods used for evaluation of post-procedure prosthetic valve regurgitation
Analyze the relative advantages/disadvantages of echo-Doppler echocardiography in assessing post-procedure valvular regurgitation
Summarize the key criteria for diagnosis of mild versus severe post procedure prosthesis regurgitation
