Transcatheter aortic valve replacement (TAVR) has become one of the main treatments for severe aortic stenosis. However, percutaneous coronary intervention (PCI) is often required in elderly patients who combine with coronary artery disease. This paper reports a case of one-stop TAVR+PCI operation for a 71-year-old male patient with left main bifurcation lesions and severe aortic stenosis. During the procedure, first of all, the coronary arteries were assessed by angiography, and the pigtail catheter was implanted in the left ventricle after the straight guidewire transvalved successfully; then PCI was performed on the diseased coronary arteries; finally, the stenosis of aortic valve was treated with TAVR. After operation, the hemodynamics of the patient was stable and symptoms were significantly improved, showing a good clinical effect of one-stop operation of TAVR+PCI.
Transcatheter aortic valve replacement (TAVR) has become a well-established treatment for patients with severe aortic stenosis. At present, TAVR has already shown noninferiority and even superiority to surgical aortic valve replacement (SAVR) in patients deemed at high or intermediate risk for SAVR. However, the long-term follow-up results of the randomized controlled trials comparing the efficacy and safety between TAVR and SAVR are still lacking in those patients who are at low risk for SAVR. This paper gives an overview and reviews results of the Evolut Low Risk trial and interprets its implications for transcatheter therapy in aortic valve diseases.
Objective To investigate the feasibility and early efficacy of transapical transcatheter aortic valve replacement (TAVR) combined with transcatheter mitral valve edge-to-edge repair (TEER) in patients with high-risk aortic valve lesions combined with severe mitral regurgitation. Methods The clinical data of patients who underwent "one-stop" transapical TAVR+TEER in our hospital from August 2022 to October 2023 were retrospectively analyzed. Results Five patients were collected, including 3 males and 2 females with a mean age of 66.6±1.8 years. Four patients had aortic valve insufficiency combined with mitral regurgitation and one had aortic valve stenosis and insufficiency combined with mitral regurgitation. All patients successfully completed transapical TAVR+TEER, and the immediate postoperative echocardiographic results revealed that none of them had more than mild perivalvular leakage and mitral regurgitation, and the prosthetic valves were in good position and function. At 1 week postoperatively, echocardiographic results showed 5 patients with no displacement of the prosthetic valve, detachment of the mitral clip, or damage to the leaflets. At 1 month postoperatively, cardiac function was improved to varying degrees in 4 patients, and 1 patient died of multiorgan failure. At 2 months postoperatively, 1 patient died of cerebrovascular accident, and at 3 months postoperatively the echocardiographic results of the remaining 3 patients revealed that there was no more than mild perivalvular leakage or mitral regurgitation, and the patients' postoperative cardiac function and daily life ability were significantly improved. Conclusion In high-risk aortic valve lesions combined with severe mitral regurgitation, "one-stop" transapical TAVR+TEER is feasible with favorable early efficacy and safety.
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.
Transcatheter aortic valve replacement and endovascular abdominal aortic repair have now become the first-line treatment options for aortic stenosis and abdominal aortic disease, respectively. For patients with both diseases, combined procedures have been reported in a few domestic and foreign publications. However, all the procedures were performed under general anesthesia. Here, we reported a case of simultaneous minimalist transfemoral transcatheter aortic valve replacement and endovascular repair of the abdominal aorta for a 78-year-old male patient with aortic stenosis and abdominal aortic ulcer, and the surgical results were satisfactory.
Transcatheter aortic valve replacement (TAVR) has been confirmed to be safety and efficacy for high-risk elderly aortic stenosis, and the clinical effect of TAVR for medium and low-risk aortic stenosis is not worse than that of surgery. The development of surgical techniques and instruments has made cardiologists attempt to broaden the surgical indications. Many elderly and high-risk patients with pure native aortic regurgitation have been treated “off label” with similar techniques, completing artificial valve replacement, restoring valve function and improving the prognosis. However, due to the high requirements of surgical techniques and surgical complications, there is a lack of randomized controlled studies to confirm its safety and effectiveness. Unlike aortic stenosis, native aortic regurgitation presents unique challenges for transcatheter valves. In this article, the authors review current advances in the treatment of aortic valve regurgitation with TAVR.
Objective To explore the clinical effects of emergency transcatheter aortic replacement (TAVR) on the treatment of patients with acute refractory heart failure or cardiogenic shock secondary to severe aortic stenosis during hospitalization. Methods The study selected 44 patients from 8 heart valve centers from January 2018 to January 2021. All patients received emergency TAVR treatment. The patients’ baseline clinical data, cardiac ultrasound indicators, and postoperative hospital stay were collected. Paired t-test and McNemar test were used to compare and analyze the preoperative and postoperative cardiac ultrasound indexes, moderate to severe aortic stenosis, and cardiac function. Results The average age of the patients was (72.0±7.9) years. Valve displacement occurred in one patient during the operation, and the surgical success rate was 97.7%. Four cases died during hospitalization, and the mortality rate was 9.1%. The median length of hospital stay was 11.5 d. The postoperative aortic valve area was significantly higher than that before surgery [(0.5±0.2) vs. (3.8±1.6) mm2, P<0.05], the mean transvalvular pressure of the aortic valve was significantly lower than that before operation [(64.0±24.9) vs. (11.3±4.6) mm Hg (1 mm Hg=0.133 kPa), P<0.05], the peak aortic flow velocity was significantly lower than that before operation [(4.5±0.7) vs. (1.9±0.7) m/s, P<0.05], the left ventricular end diastolic inner diameter was lower than that before operation [(59.0±7.2) vs. (56.1±7.3) mm, P<0.05], the left ventricular ejection fraction increased significantly compared with that before operation [(30.1±10.4)% vs. (40.9±11.0)%, P<0.05], and the cardiac function improved significantly compared with that before operation (P<0.05). During the operation, 2 cases (4.5%) underwent valve-in-valve implantation, 11 cases (25.0%) underwent percutaneous coronary intervention during the same period. During the postoperative hospital stay, 1 case (2.3%) developed stroke, 3 cases (6.8%) experienced severe bleeding, 5 cases (11.4%) had severe vascular complications, 2 cases (4.5%) experienced acute myocardial infarction, 30 cases (68.2%) had small or trace paravalvular regurgitation, 3 cases (6.8%) received permanent pacemaker implantation, and 5 cases (11.4%) developed acute kidney injury. Conclustion Emergency TAVR is an effective and feasible treatment plan for patients with acute refractory heart failure or cardiogenic shock secondary to severe aortic stenosis.
ObjectiveTo analyze the short-term clinical efficacy and prognosis of one-stop transcatheter aortic valve replacement (TAVR)+percutaneous coronary intervention (PCI) in the treatment of aortic valve disease with coronary heart disease. MethodsThe clinical data of patients with aortic valve disease complicated with coronary heart disease who underwent one-stop TAVR+PCI treatment at the Department of Cardiovascular Surgery, the Second Hospital of Hebei Medical University from January 2018 to June 2023 were retrospective analyzed. The preoperative and postoperative clinical data were compared, and 1-month follow-up results were recorded. ResultsA total of 37 patients were enrolled, including 22 males and 15 females, with an average age of 69.14±6.47 years. Thirty-six patients recovered and were discharged after the surgery, and 1 (2.7%) patient died during the surgery. Self-expanding TAVR valves were implanted through the femoral artery in all patients. One coronary artery was opened by PCI in 35 (94.6%) patients, and two coronary arteries were opened by PCI in 2 (5.4%) patients. All PCI opened arteries had a stenosis>70%. During the postoperative hospitalization, the complications included pulmonary infection in 11 (30.6%) patients, severe pneumonia in 10 (27.8%) patients, liver function injury in 14 (38.9%) patients, renal function injury in 5 (13.9%) patients, cerebral infarction in 1 (2.8%) patient, atrial fibrillation in 1 (2.8%) patient, ventricular premature beats in 2 (5.6%) patients, atrioventricular block in 2 (5.6%) patients, and complete left bundle branch block in 5 (13.9%) patients. The median postoperative ventilation assistance time was 12.0 (0.0, 17.0) h, the ICU monitoring time was 1.0 (0.0, 2.0) d, and the postoperative hospitalization time was 5.0 (4.0, 7.0) d. There was a significant improvement in the New York Heart Association cardiac function grading after surgery (P<0.001). After surgery, there were 21 (58.3%) patients had minor perivalve leakage, 6 (16.7%) patients had minor to moderate perivalve leakage, and no moderate or above degree of perivalve leakage. After one month of postoperative follow-up, 36 patients showed significant improvement in heart function. There were no patients with recurrent acute coronary syndrome, re-PCI, or cardiovascular system disease related re-hospitalization. ConclusionThe one-stop TAVR+PCI treatment for patients with aortic valve disease and coronary heart disease can obtain satisfactory short-term clinical efficacy, which is worth further trying and studying.
Transcatheter aortic valve replacement (TAVR) has become a common theraputic option for aortic stenosis, but the evidence for precise anatomy for TAVR is accumulating. This paper presents the case of an 71-year-old female patient who had an extremely high risk of coronary obstruction due to both coronary ostia lying too low. The patient underwent TAVR with the help of coronary protection successfully. During the procedure, the patient was protected with wires only for both coronaries. After deployment, angiofluoroscopy suggested that chimney stenting should be applied for left coronary. The whole procedure was unenventful and both coronaries were seen.
Aortic stenosis (AS) is the most common primary valve lesion requiring surgery or transcatheter intervention in modern era. Its prevalence is rising rapidly as a consequence of the aging population. Transcatheter aortic valve replacement (TAVR) as a therapy option for older high-risk symptomatic severe AS patients has emerged and is currently extending its indications towards surgery intermediate- and low-risk subjects. Considering the common characteristics of frailty and high comorbidity among AS patients, cardiac rehabilitation (CR) has been proven to improve not only survival but also quality of life in previous reports. CR as a classⅠ recommendation in guidelines for the prevention and treatment of cardiovascular disease has been widely used in clinical practice. The purpose of this article is to sort out the current CR programs for TAVR patients in global medical management, and explore the CR optimization program fit for China medical model in post COVID-19 pandemic era.
