Objective To discuss the key points of anesthesia for patients undergoing transcatheter aortic valve implantation (TAVI) surgery. Methods We retrospectively collected and analyzed the data of 70 patients who underwent TAVI in the Department of Cardiovascular Surgery, West China Hospital from March 2014 to October 2015. There were 39 males and 31 females with an average age of 73.7±4.5 years. The perioperative preparation and anesthesia points of TAVI were summarized. Results All of the 70 included patients were aged and at high risk severe comorbidities such as ischemic heart disease and stroke. The aortic stenosis and regurgitation occurred in 39 and 31 patients respectively. No patients died during the surgery. The total success rate was 95.7%. Conclusion TAVI is a complex procedure for high risk patients and need more attention during anesthesia. The successful conduction of the procedure requires the whole team to prepare carefully and cooperate closely.
Objective To report our experience with enhanced recovery after surgery (ERAS) protocol in patients undergoing transapical transcatheter aortic valve implantation (TAVI) and to determine perioperative predictors for ERAS failure. Methods Between May 2018 and January 2019, 80 patients undergoing TAVI in our hospital were recruited. Among them, 40 patients (24 males, 16 females, aged 73.0±5.0 years) successfully received ERAS, defined as successful extubation in operating room (an ERAS group) and the other 40 patients (28 males, 12 females, aged 73.0±7.0 years, a non-ERAS group) failed to perform ERAS. Results Compared with the non-ERAS group, patients in the ERAS group were associated with a significantly lower incidence of postoperative complications (30.0% vs. 52.5%, P=0.04), shorter postoperative ICU stay (2.2±0.4 d vs. 4.0±4.8 d, P=0.00) and hospital stay (7.0±2.3 d vs. 9.5±4.8 d, P=0.00), and less medical cost (311±20 thousand yuan vs. 347±80 thousand yuan, P=0.00). Independent predictors of ERAS failure were poor preoperative heart function and elevated B-type natriuretic peptides. Conclusion ERAS protocol is feasible and effective in patients undergoing TAVI. Poor preoperative heart function is an independent predictor of failure in early extubation which, in turn, is associated with prolonged ICU and hospital stay and dramatic worsening of patient outcomes.
ObjectiveTo determine the clinical efficacy of transapical transcatheter mitral valve-in-valve treatment for patients with deteriorated mitral bioprosthesis after aortic-mitral double valve replacement.MethodsThe clinical data of 9 patients who underwent transapical transcatheter mitral valve-in-valve implantation after aortic-mitral double valve replacement due to mitral bioprosthesis deterioration from May 2020 to January 2021 in our hospital were retrospectively analyzed, including 4 males and 5 females with a mean age of 72.44±7.57 years.ResultsSurgeries were performed successfully in all patients with no conversion to median sternotomy. The mean procedural time was 101.33±48.49 min, the mechanical ventilation time was 23.11±26.54 h, the ICU stay was 1.89±1.05 d and the postoperative hospital stay was 6.11±2.02 d. Residual mild mitral regurgitation was only observed in 1 patient. Only 1 patient needed postoperative blood transfusion. No major complications were observed in all patients. There was no death in postoperative 90 days.ConclusionFor patients with deteriorated mitral bioprosthesis after aortic-mitral double valve replacement, transapical transcatheter mitral valve-in-valve implantation achieves good clinical results and effectively improves the hemodynamics without increasing the risk of postoperative left ventricular outflow tract obstruction. The surgery is feasible and effective.
An 81-year-old male patient was admitted to Guangdong Provincial People's Hospital due to chest distress and shortness of breath after activity for half a year. Examination after admission revealed severe aortic insufficiency, tricuspid aortic valve and extremely horizontal aorta with an aortic root angulation of 99°. The Society of Thoracic Surgeons score was 7%. And taking the strong demand of the patient and his family into consideration, we decided to perform transapical transcatheter aortic valve replacement after multidisciplinary evaluation. The procedure was successfully performed by means of low deployment land zone and traction of pre-exist Prolene suture. Three-month follow-up confirmed the normal function of aortic prosthetic valve without residual regurgitation. This case provides a reference for the interventional treatment in patients with extremely horizontal aorta.
ObjectiveTo compare the in-hospital outcomes of transapical transcatheter aortic valve replacement (TA-TAVR) for bicuspid aortic valve (BAV) patients and tricuspid aortic valve (TAV) patients. MethodsPatients (including BAV and TAV patients) who underwent TA-TAVR with the J-ValveTM in West China Hospital from July 2014 to July 2020 were included consecutively. The clinical outcomes of the patients were analyzed. ResultsA total of 354 patients were included in the study, 75 in the BAV group and 279 in the TAV group. There were 229 males and 125 females with a mean age of 72.2±6.0 years. No death occurred during the procedure, and the overall technical success rate was 97.7%. The all-cause in-hospital mortality rate was 1.4%. Twenty (26.7%) patients with BAV and 46 (16.5%) patients with TAV had mild or higher perivalvular leaks immediately after the procedure. No patients with BAV required permanent pacemaker implantation postoperatively, while 13 (4.7%) TAV patients required permanent pacemaker implantation, with an overall pacemaker implantation rate of 3.7%. One (1.3%) BAV patient and 7 (2.5%) TAV patients developed acute kidney injury postoperatively. One (1.3%) BAV patient and 1 (0.4%) TAV patient developed perioperative myocardial infarction. The average postoperative hospital stay was 7.6±3.6 d for BAV patients and 8.6±6.1 d for TAV patients. There was no statistical difference in primary or secondary in-hospital outcomes between BAV and TAV patients (P>0.05). ConclusionCompared to TAV patients, BAV patients have similar in-hospital outcomes, with a low incidence of adverse clinical outcomes, which provides preliminary evidence for its implementation in Chinese patients with a high proportion of BAV.
