Tricuspid Regurgita>on: Which Mechanism?

TRV max = 2.8 m/s

•  76 year-old lady •  Sclerodermia •  Pacemaker implantation 10 months before •  Known moderate TR •  Admitted for decompensated right heart failure


Tricuspid Regurgita>on: Which Mechanism?


Tricuspid Regurgita>on: No Pacemaker Interference


Tricuspid Regurgita>on: a[er 1 week of diure>cs

TRV max = 3.8 m/s

Total time for generating the 3D model of TV was 30 min

•  The tangible 3D model of TV

enhanced the perception of the complex 3D shape of the TV and of the non-planarity of TV annulus

3D PRINTING OF TRICUSPID VALVE USING 3DTTE

•  This technique could be potentially integrated in clinical practice to assist the

surgical planning and education, and the simulation of the outcomes of various percutaneus TV interventions
