TRANSCATHETER AORTIC VALVE REIMPLANTATION (TAVI) VALVE IN VALVE

CASE REPORT

Abstract

Introduction: The advent of transcatheter aortic valve replacement (TAVI) has changed the paradigm for managing aortic valve disease. TAVI has become specific in the last decade as a less invasive treatment alternative to the conventional surgical procedure, for inoperable, medium and high surgical risk patients. Objective: to report a case of a previous patient who underwent TAVI 5 years ago due to severe symptomatic aortic stenosis that evolved with degeneration of the prosthesis, progressing with implicit worsening of the functional class, undergoing TAVI valve-invalve (ViV). Case report: This is a patient with multiple comorbidities who underwent TAVI in 2016 due to severe aortic stenosis. She returned to the hemodynamics service with dyspnea at rest, orthopnea, paroxysmal nocturnal dyspnea and typical precordial pain. Echocardiogram of aortic prosthesis dysfunction with severe stenosis. So, it was decided to perform TAVI ViV to treat an elderly patient with severe organic fragility and high surgical risk. Intraoperatively, a reduction in transvalvular gradients was evidenced. Postoperatively, the patient evolved with significant improvement in her previous symptoms and was discharged after 3 days for outpatient follow-up. Conclusion: The ViV procedure is a safe and less invasive alternative for the treatment of dysfunctional bioprostheses. The current literature reports low morbidity and mortality rates of patients related to ViV improvement and survival.
