Background

Background: Severe aortic stenosis (AS) is one of the common and serious valvular problemsStandard treatment for symptomatic severe AS is surgical aortic valve replacement (SAVR) or Transcatheter aortic valve implantation (TAVI). Balloon aortic valvuloplasty (BAV) has been used as a bridge decision, rescue therapy, bridge to major non-cardiac surgery and palliative therapy. However, in Thailand, there are scant data in term of feasibility and the outcomes of BAV.

Methods

Methods: Consecutive symptomatic severe AS patients who underwent BAV at Thammasat University Hospital between June 2018 and August 2021 were identified. Patient’s characteristics, echocardiographic parameters, procedural data, hemodynamic parameters pre and post BAV were collected. We evaluate success rate of BAV, peri-procedural and post BAV complications, and 30-day all-cause mortality after BAV.

Results

Results: Of 26 patients underwent BAV, mean age was 80.96 ± 10.69 year. The median STS score was 5.44 and 14 patients (53.8%) were in NYHA class 3. Indications were bridging procedure (bridging to SAVR/TAVI, bridging to non-cardiac surgery, bridging to decision) 73.1%, cardiogenic shock 11.5% and palliative therapy 15.4% respectively. Success rate was 84.6%. The mean pressure gradient reduced from 50.56 ± 22.64mmHg to 38.74 ± 17.17mmHg and AVA increased from 0.55 ± 0.18 cm2 to 0.78 ± 0.30 cm2. Peri-procedural complications was 19.23% (n=5) including vascular complications (n=1), arrhythmia (n=2), blood transfusion (n=1), cardiogenic shock (n=1) and infection (UTI; n=1). Intraprocedural mortality was 3.85% (n=1) and 30-day all-cause mortality was 15.38% (n=4). The 3-month survival from death and heart failure was 80.77% (n=21).

Conclusion

Conclusions: Our registry showed the feasibility, efficacy and safety outcomes of BAV in symptomatic severe AS patients. And 3-month survival from CV event were acceptable.
