Abstract:
Objective:To analysis the mid-stage prognosis of transapical aortic valve implantation(TA-TAVI) using J-Valve? system for the treatment of high-risk aortic regurgitation(AR) patients.Methods:Data of 25 patients with aortic regurgitation who had underwent transapical aortic valve implantation using J-Valve? system were collected in the Second Affiliated Hospital of Medical College of ZheJiang University from September 2016 to June 2020 . Analysis and summarize their postoperative all-cause mortality, the incidence of adverse events and the improvement in cardiac function.Results:There were 25 patients, including 19 males, the age rage from 59-83 years, the average age was(72.3±27.11) years. The levels of aortic regurgitation was evaluated by transthoracic echocardiography preoperatively, showed that severe AR accounted for 88%. The New York Heart Association(NYHA) of grade 3 or above was 92%. The most common comorbidity was hypertension, accounted for 68%. Coronary heart disease and history of cardiac surgery was 5 and 3 relatively in this study. The Society of Thoracic Surgeons score before surgery was 1.511%-27.674%, the average of STS score was 4.27(2.914-6.033)%. Successful J-Valve implantation was obtained in all 25 cases, no conversion to thoracotomy. After surgery, 2 patients required permanent pacemaker implantation, 1 patient needed continuous renal replacement therapy(CRRT) due to acute kidney injury, 1 occurred moderate or above paravalvular leak. The results showed good therapeutic effects in early-stage, low incidences of adverse events. The continued improvement of cardiac function and ventricular reverse remodeling could be observed in mid-stage.Conclusion:In this study, we can summarize that high-risk patients with aortic regurgitation treated with transapical aortic valve implantation using J-Valve? system can acquire great perioperative safety and mid-stage prognosis.
