  • Simultaneous TAVI and McKeown for esophageal cancer with severe aortic regurgitation: A case report

    A 71-year-old male presented with esophageal cancer and severe aortic valve regurgitation. Treatment strategies for such patients are controversial. Considering the risks of cardiopulmonary bypass and potential esophageal cancer metastasis, we successfully performed transcatheter aortic valve implantation and minimally invasive three-incision thoracolaparoscopy combined with radical resection of esophageal cancer (McKeown) simultaneously in the elderly patient who did not require neoadjuvant treatment. This dual minimally invasive procedure took 6 hours and the patient recovered smoothly without any surgical complications.

  • Short-term results of valve-in-valve transcatheter aortic valve implantation in patients with degenerated bioprosthesis

    Objective To summarize the short-term results of valve-in-valve transcatheter aortic valve implantation (ViV-TAVI) in the treatment of bioprosthetic valve failure after aortic valve replacement. Methods We reviewed the clinical data of patients who underwent ViV-TAVI from 2021 to 2022 in the First Affiliated Hospital of Zhengzhou University. The valve function was evaluated by echocardiography before operation, immediately after operation and 3 months after operation. The all-cause death and main complications during hospitalization were analyzed. Results A total of 13 patients were enrolled, including 8 males and 5 females with a mean age of (65.9±8.5) years, and the interval time between aortic valve replacement and ViV-TAVI was (8.5±3.4) years. The Society of Thoracic Surgeons mortality risk score was 10.3%±3.2%. None of the 13 patients had abnormal valve function after operation. The mean transvalvular pressure gradient of aortic valve was decreased (P<0.001), the peak flow velocity of aortic valve was decreased (P<0.001), and the left ventricular ejection fraction was not changed significantly (P=0.480). There were slight perivalvular leakage in 2 patients and slight valve regurgitation in 3 patients. Three months after operation, the mean transvalvular pressure difference and peak flow velocity of aortic valve in 12 patients were significantly decreased compared with those before operation (P≤0.001). Conclusion This study demonstrates that ViV-TAVI for the treatment of bioprosthetic valve failure after aortic valve replacement is associated with favorable clinical and functional cardiovascular benefits, the short-term results are satisfactory.

  • First robotic-assisted balloon-expandable transcatheter aortic valve implantation for severe aortic stenosis: A two-case report

    This study reports the first successful clinical application of a robotic-assisted system in transcatheter balloon-expandable aortic valve implantation using the Edwards SAPIEN 3 valve. Two male patients, aged 60 and 63 years, respectively, presented with severe aortic stenosis confirmed by echocardiography and computed tomography, showing significant valvular calcification and elevated transvalvular pressure gradients, meeting the indications for transcatheter aortic valve implantation (TAVI). Both procedures were performed via the right femoral artery using a robotic-assisted delivery and positioning system developed by Shanghai Surgerii Medical Technology Co., Ltd. The operator controlled the delivery system and valve positioning precisely through the console, while the assistant performed balloon expansion and valve deployment. Both procedures were completed successfully without intraoperative complications. The operative times were 75 minutes and 67 minutes, with fluoroscopy times of 16 minutes and 23 minutes, and radiation doses of 714 mGy and 971 mGy, respectively. Postoperative echocardiography demonstrated well-functioning prosthetic valves, with mean transvalvular pressure gradients of 3.9 mm Hg and 8.0 mm Hg, and none or trivial paravalvular leakage. No coronary obstruction, conduction disturbance, or vascular complications were observed.This report represents the world’s first clinical use of a robotic-assisted system for balloon-expandable TAVI. It confirms the feasibility and safety of robotic assistance in transcatheter valve delivery and positioning, offering a new approach to enhance procedural precision and stability, and providing valuable insights for the future development of intelligent, minimally invasive therapies for structural heart disease.

  • Sutureless aortic versus transcatheter aortic valve implantation for aortic valve disease: A systematic review and meta-analysis of propensity-matched studies

    ObjectiveTo evaluate the clinical outcomes of sutureless aortic valve replacement (SU-AVR) and transcatheter aortic valve implantation (TAVI) for aortic valve disease. MethodsWe conducted a computer-based search of databases including CNKI, WanFang Data, VIP, CBM, PubMed, The Cochrane Library, EMbase and Web of Science from the inception of the databases to March 2024. Two reviewers independently screened articles, extracted data and used the Cochrane bias risk assessment tool to evaluate the quality of the included studies. Meta-analysis was performed using Stata 18 software. ResultsThe included 17 studies using propensity-matched analysis consisted of 6 630 patients, including 3 319 patients in the SU-AVR group and 3 311 patients in the TAVI group. The SU-AVR group had lower mortality than the TAVI group at 1-year [RR=0.58, 95%CI(0.38, 0.87), P=0.009], 2-year [RR=0.61, 95%CI(0.43,0.85), P=0.004] and 5-year [RR=0.63, 95%CI(0.50,0.79), P=0.000]. The SU-AVR group had a significantly lower rate of new permanent pacemaker implantation (PPI) [RR=0.75, 95%CI(0.58, 0.98), P=0.037], moderate-to-severe paravalvular leak (PVL) [RR=0.20, 95%CI(0.12, 0.32), P=0.000], myocardial infarction(MI)[RR=0.30, 95%CI (0.11,0.80), P=0.017], more-than-mild residual aortic regurgitation (AR)[RR=0.29, 95%CI(0.17, 0.48), P=0.000]. In addition, the SU-AVR group had a higher postoperative mean aortic gradient [SMD=0.39, 95%CI (0.17, 0.62), P=0.000]than the TAVI group. Conclusion The early and mid-term clinical outcomes of SU-AVR were superior compared to TAVI.

  • Early clinical experience of transcatheter aortic valve implantation via apical approach for high-risk aortic valve disease in single-center

    ObjectiveTo summarize the clinical experience in the treatment of high-risk patients with severe aortic valve disease by transcatheter aortic valve implantation (TAVI) via heart apex approach and to evaluate the early efficacy.MethodFive patients who underwent TAVI via heart apex approach from September 2017 to February 2019 in Henan Thoracic Hospital were retrospectively analyzed, including 3 males and 2 females, aged 65-84 (74.6±4.5) years.ResultAll operations were performed through a small left incision into the thoracic cavity (3-5 cm), and then through the J-Valve transport system, the aortic valve was successfully released via heart apex after precise positioning under digital subtraction angiography. One patient developed ventricular fibrillation during the operation, and the operation was completed with the assistance of emergency femoral arteriovenous catheterization cardiopulmonary bypass; one patient underwent percutaneous coronary intervention first because of severe coronary stenosis; one patient had paroxysmal atrial fibrillation during the perioperative period, and had hepatorenal insufficiency and thrombocytopenia after the operation, and was improved after medical treatment; one patient had perivalvular leak during the operation, and was improved after re-implantation of the valve; one patient was in stable condition during operation and recovered smoothly after operation. Surgery was successful in all 5 patients. The follow-up time was 2-19 months, and the early clinical effect was good.ConclusionThe short-term clinical efficacy of TAVI via heart apex approach in the treatment of high-risk severe aortic valve disease is definite and safe, but the long-term and medium-term effects need to be further evaluated.

  • Implications of five-year outcomes of PERIGON trial for bioprosthetic aortic valve replacement

    For patients with aortic valve disease who require replacement of their native valve, surgical aortic valve replacement (SAVR) has been the standard of care. Due to the hemorrhage and thromboembolic risks of long-term anticoagulation therapy for mechanical prosthesis, bioprosthetic aortic valve replacement (AVR) has a trend to be used in younger patients, which raising the concern for the durability of bioprosthetic valves. The newly published 5-year outcomes of PERIGON trial, with no structural valve deterioration, again demonstrated the favorable durability of the new generation bioprosthetic valves, further providing the evidence of using bioprosthetic AVR in younger patients. At the meantime, the rapid progress of transcatheter aortic valve implantation (TAVI) has brought a new treatment option. For younger patients with low risks, choosing SAVR or TAVI becomes a critical decision. This paper reviews the outcomes of PERIGON trial and its implications to the clinical practice and research of bioprosthetic AVR.

  • Advances in antithrombotic therapy in patients with valvular heart disease after transcatheter intervention

    As technology advances, current evidence supports the use of devices for valvular heart disease interventions, including transcatheter aortic valve implantation, transcatheter mitral or tricuspid valve repair, and transcatheter mitral valve implantation. These procedures require antithrombotic therapy to prevent thromboembolic events during the perioperative period, and these therapies are associated with an increased risk of bleeding complications. To date, there are challenges and controversies regarding how to balance the risk of thrombosis and bleeding in these patients, and therefore the optimal antithrombotic regimen remains unclear. In this review, we summarize the current evidence for antithrombotic therapy after transcatheter intervention in patients with valvular heart disease and highlight the importance of an individualized approach in targeting these patients.

  • Enhanced recovery after surgery protocol in patients undergoing transapical transcatheter aortic valve implantation

    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.

  • Vitamin K vs. non-vitamin K antagonist treatment in high-risk atrial fibrillation patients after transcatheter aortic valve implantation: A systematic review and meta-analysis

    ObjectiveTo evaluate the anticoagulation efficacy of non-vitamin K antagonist oral anticoagulants (NOACs) and vitamin K antagonists (VKAs) in patients with high-risk atrial fibrillation (AF) undergoing transcatheter aortic valve implantation (TAVI). MethodsA computer-based search was conducted on PubMed, EMbase, The Cochrane Library, CNKI, SinoMed, and VIP databases to identify studies on the application of NOACs and VKAs in high-risk AF patients after TAVI. The search period was from database inception to January 2023. The quality of the included studies was assessed using the Cochrane risk assessment tool and the Newcastle-Ottawa Scale (NOS). Meta-analysis was performed using RevMan 5.4 software. ResultsA total of 7 studies involving 24 592 patients were included. The meta-analysis results showed that compared to patients using VKAs, those treated with NOACs had a significantly lower risk of all-cause mortality [RR=0.74, 95%CI (0.58, 0.94), P=0.01]. Subgroup analysis indicated that when the follow-up period was less than 1 year, there was no significant difference in all-cause mortality between the NOAC and VKA groups [RR=0.57, 95%CI (0.17, 1.88), P=0.35]; however, when the follow-up period was ≥1 year, the VKA group had a higher all-cause mortality rate than the NOAC group, with a statistically significant difference [RR=0.73, 95%CI (0.57, 0.95), P=0.02]. No significant differences were found between the two groups regarding early stroke [RR=0.50, 95%CI (0.19, 1.28), P=0.15], stroke during follow-up [RR=1.04, 95%CI (0.88, 1.22), P=0.64], bleeding [RR=0.94, 95%CI (0.73, 1.21), P=0.61], major or life-threatening bleeding [RR=0.80, 95%CI (0.49, 1.31), P=0.38], or acute kidney injury [RR=0.51, 95%CI (0.16, 1.59), P=0.24]. Conclusion Compared to VKAs, the use of NOACs in patients with high-risk AF undergoing TAVI may reduce the risk of all-cause mortality, especially during long-term anticoagulation therapy, potentially offering greater benefits. However, further evidence from randomized controlled trials is needed to confirm these findings.
