• W2018447510 abstract "This study aimed to determine the success, complications, and survival of patients after balloon aortic valvuloplasty (BAV).The introduction of transcatheter aortic valve implantation (TAVI) BAV has led to a revival in the treatment of patients with severe aortic stenosis.A cohort of 262 patients with severe aortic stenosis underwent 301 BAV procedures. Of these, 39 (14.8%) patients had ≥2 BAV procedures. Clinical, hemodynamic, and follow-up mortality data were collected.The cohort mean age was 81.7 ± 9.8 years, and the mean Society of Thoracic Surgeons and logistic EuroSCORE (European System for Cardiac Operative Risk Evaluation) was 13.3 ± 6.7 and 45.6 ± 21.6, respectively. BAV was performed as a bridge to TAVI or to surgical aortic valve replacement in 28 patients (10.6%) and for symptom relief in 234 (89.4%). The mean aortic valve area (AVA) increased from 0.58 ± 0.3 cm(2) to 0.96 ± 0.3 cm(2) (p < 0.001). Of these, 111 (45.0%) had final AVA >1 cm(2), and in 195 patients (79%), AVA increased by >40%. De novo BAV resulted in a higher mean increase in AVA 0.41 ± 0.24 cm(2) versus 0.28 ± 0.24 cm(2) in redo BAV (p = 0.003). Serious adverse events occurred in 47 patients (15.6%), intraprocedural death in 5 (1.6%), stroke in 6 (1.99%), coronary occlusion in 2 (0.66%), severe aortic regurgitation in 4 (1.3%), resuscitation/cardioversion in 5 (1.6%), tamponade in 1 (0.33%), and permanent pacemaker in 3 (0.99%). A vascular complication occurred in 21 patients (6.9%); 34 (11.3%) had a post-procedure rise in creatinine >50%; and 3 (0.99%) required hemodialysis. During median follow-up of 181 days, the mortality rate was 50% (n = 131). The mortality rate in the group with final AVA >1 cm(2) was significantly lower than in the group with final AVA of <1 cm(2) (36.4% vs. 57.9%, p < 0.001). Final AVA was associated with lower mortality (hazard ratio: 0.46, p = 0.03). BAV as a bridge to TAVI or surgical aortic valve replacement had a better outcome compared with BAV alone: mortality rate 7 (25%) versus 124 (52.9%), respectively (p < 0.0001).Long-term survival is poor after BAV alone. BAV as a bridge to percutaneous or surgical aortic valve replacement is feasible, safe, and associated with better outcome than BAV alone." @default.
