Abstract:
A 47-year-old patient was experiencing dyspnea and fatigue concerning for right ventricular hypertension and new heart failure. Because of the risks associated with catheter entrapment, prosthetic valve leaflet damage, and valve thrombosis associated with crossing a mechanical valve, a novel technique was used for diagnostic left and right heart catheterization in a patient with mechanical tricuspid valve replacement and tortuous pulmonary arteries. Using a percutaneous subxiphoid approach to avoid traversing the mechanical valve without discontinuing anticoagulation, a Volcano fractional flow reserve pressure wire (Philips Volcano) was advanced for distal measurements of pressures and saturations.
