Aspiration of Left Atrial Masses Using the Large-Bore Manual Aspiration System: The ASPIRATE LA Procedure.

Transcatheter mass extraction of left-sided cardiac masses has gained popularity in recent years, with scarce data on effectiveness, safety, and types of devices used. Mostly, left-sided aspirations use mechanical and continuous-flow-mediated devices (the AngioVac [AngioDynamics] and Penumbra systems [Penumbra]). To our knowledge, the use of manual aspiration devices has not been reported yet.

Successful Transcatheter Mitral Valve Mass Extraction With Complete Resolution of the Severe Mitral Regurgitation.

Interest has arisen in exploring the off-label application of left-sided percutaneous mechanical aspiration, where conventional management strategies may not suffice. Percutaneous mechanical aspiration has been shown to be effective as a diagnostic and therapeutic intervention in select patients with infective endocarditis. This paper hereby reports the first case of a successful transeptal large bore manual aspiration device (AlphaVac; Angiodynamics) for nonbacterial thrombotic endocarditis with total resolution of associated severe mitral valve regurgitation.
