Introducion. Balloon aoric valvuloplasty (BAV) is a percutaneous treatment opion for aoric stenosis (AS). Because of early restenosis and poor long-term survival, it is used as a bridge to surgery (SAVR) or transcatheter aoric valve replacement (TAVR), in hemodinamically unstable paients or paients that require urgent non-cardiac surgery.
Aim. The aim of this study was to evaluate all the BAV procedures performed in our centre in 2010 and to report our experience with BAV as a potenial bridge to deiniive therapy or as a palliaive treatment.
Methods. We retrospecively analyzed all the paients who underwent percutaneous treatment of aoric stenosis in our insituion between January and December 2010. We straiied our cohort into 3 groups: BAV as a bridge to TAVR or SAVR, BAV as a inal therapy and TAVR without prior BAV. We evaluated paient characterisics, echocardiographic data and peri-procedural complicaions in each cohort. Survival was evaluated using Kaplan-Meier analysis.
Results. We included 86 high risk symptomaic paients with mean age of 82.2 ± 5.0 years and mean logisic EuroSCORE of 19.2 ± 11.8 %. Ater BAV we observed a signiicant decrease in mean transvalvular gradient (from 43.8 ± 14.4 to 33.5 ± 12.3 mmHg; p < 0.01) and a signiicant increase in aoric valve area ater BAV (from 0.6 ± 0.2 to 0.8 ± 0.3 cm2; p < 0.01). Systolic pulmonary artery pressure, let ventricular ejecion fracion and mitral regurgitaion did not change signiicantly. Major intrahospital complicaions occurred in 5 paients (6.5 %), without any death related to the procedure. BAV as a bridge to TAVR had a beter outcome compared with BAV alone.
Conclusion. BAV is a feasible and reasonably safe approach for temporary relief of symptoms, improvement of quality of life, decrease of surgical risk prior major non-cardiac surgery or as a bridge to surgical or transcatheter aoric valve implantaion in severe aoric stenosis.
