Abstract
Objective To retrospective analyze clinical efficacy and safety of transcatheter aortic valve implantation(TA-VI)for severe aortic stenosis(AS)and(or)aortic valve regurgitation(AR).Methods From January 2021 to April 2023,a retro-spective analysis was performed for clinical data of 45 patients who underwent TAVI in our hospital,the mean age was(71.2±7.7)years,28 patients(62.2%)were male.The Society of Thoracic Surgeons predicted risk of mortality(STS)scored an average score of(8.4±1.2).There were 11 cases(24.4%)with simple severe AS alone,1 case(2.2%)with simple severe AR due to biovalvedecay,8 cases(17.8%)with severe AS and AR and moderate AR,1 case(2.2%)with severe AS and AR,3 cases(6.7%)with severe AR and moderate AS.The parameters of postoperative aortic valve blood flow and the effect of short-term fol-low-up at 1 month after surgery were analyzed.Results All 45 patients had successful TAVI surgery,and the peak blood flow ve-locity of the aortic valve decreased to(2.2±0.5)m/s,and the average transvalvular pressure difference of the aortic valve de-creased to(10.9±5.6)mmHg.At short-term follow-up 1 month after surgery,7 patients(15.6%)had mild paravalvular leakage,3 patients(6.7%)had three-degree atrioventricular block with artificial permanent pacemaker placement,5 cases(11.1%)of stroke,1 case(2.2%)of acute coronary event,and 2 patients(4.4%)died.Conclusion For patients with severe AS and(or)AR who have surgical contraindications or are unwilling to undergo surgery,TAVI surgery could effectively reduce transvalvular pressure difference,improve symptoms,and be clinically safe and effective.关键词
