Impact of tricuspid valve insufficiency on the performance of left ventricular assist devices

Abstract

Objective: To evaluate the impact of severe tricuspid valve insufficiency (TVI) at the time of left ventricular assist device (LVAD) implantation on the hemodynamic and LVAD parameters in an acute ovine model.

Tricuspid surgery at the time of LVAD implant: A critique

“…Another confounder is the relationship between tricuspid regurgitation and RV failure. Significant tricuspid regurgitation is well-tolerated in LVAD patients without RV dysfunction ( 16 ) and RV dysfunction is found among patients with and without significant TR. While TR is treatment variable under study, RV dysfunction is the clinical variable associated with outcome.…”

Commentary: Leaving tricuspid regurgitation unrepaired at the time of left ventricular assist device implantation?

“…Gomez Hamacher and colleagues describe the impact of tricuspid valve insufficiency on the performance of left ventricular assist devices (LVADs). 1 They created an ovine model of left heart failure using coronary ligations in 10 animals. The animals were allowed to recover for 2 to 3 weeks, after which they were placed on bypass and underwent LVAD implantation.…”
