PM121 Incidence and predictors of events following TAVI with a self-expanding valve: immediate and mid-term outcomes

Abstract

O ST E R A B ST R A C T S Methods: A cohort of 8 patients with severe aortic stennosis underwent 9 BAV procedures. Intra-cardiac echocardiography (ICE) guided trans-septal puncture and BAV using Inoue balloon were performed antegradely. Clinical, hemodynamin, and follow-up mortality data were collected. Results: The mean age was 81.0 9.2 years, and the vast majority of patients had comorbidities and high-risk features including 4 hemodialysis patients(50%). The mean Society of Thoracic Surgeons and EuroSCOREII (European System for Cardiac Operative Risk Evaluation) was 10.6 5.2 and 16.0 7.8, respectively. BAV was performed for symptom relief in all patients (100%). The mean aortic valve area (AVA) increased from 0.69 0.32 cm(2) to 1.17 0.4 cm(2) (p 1 cm(2), and in 7 patients (88%), AVA increased by >50%. There was no death, stroke, coronary occlusion, severe aortic regurgitation, cardiac tamponade. One patient developed sepsis and worsening of renal failure. During median follow-up of 194 days, the mortality rate was 25% (n 1⁄4 2). Conclusion: In severe AS patients who have high risk for surgical AVR, antegrade BAV using Inoue balloon may be feasible with good initial and mid-term outcomes. Disclosure of Interest: None Declared
