Abstract:
Transcatheter tricuspid valve replacement(TTVR)is characterized by minimal invasiveness,rapid recovery,and a significantly lower perioperative mortality rate compared to surgical procedures.It is the preferred treatment for patients with bioprosthetic valve failure following surgical tricuspid valve replacement.However,when the delivery system is relatively bulky,challenges can arise due to the reduced orifice area post-surgery and the constraints imposed by the valve frame.These factors may result in difficulties advancing the delivery system.Additionally,the tortuous right heart pathway and limited support provided by the guide wire further increase the complexity of the procedure.In the present case,the patient experienced bioprosthetic valve failure following surgical tricuspid valve replacement.During TTVR,the advancement of the delivery system across the tricuspid valve encountered difficulties.Our team promptly employed the parallel anchoring-supporting sheath and snared wire(PASS)technique,pioneered at our center.Utilizing a large supporting sheath in conjunction with a snare to secure the tip of a extra-stiff guide wire,we straightened the tortuous pathway,providing additional support to the extra-stiff guide wire.This maneuver successfully facilitated the advancement of the delivery system across the tricuspid valve,offering a practical and effective solution for overcoming intraoperative challenges associated with TTVR.
