Unpredictable Mechanical Mitral Valve Leaflet Motion in a Patient With Continuous-Flow LVAD.

ABSTRACT:

Background

Patients with a pre-existing mechanical mitral valve (MV) who undergo left ventricular assist device (LVAD) implantation pose unique challenges owing to interactions between the device and valve.

Case summary

A 56-year-old man with a history of mechanical MV replacement and multiple interventions underwent LVAD implantation. After LVAD, the mechanical MV exhibited dynamic changes of leaflet mobility, from both stuck open to both moving freely. Despite these abnormalities, there was no clinically significant mitral regurgitation or hemodynamic impact. The patient was managed without surgery or thrombolytics and experienced no adverse clinical consequences related to mechanical MV dysfunction.

Discussion

This case highlights the dynamic behavior of a mechanic
