ObjectiveTo summarize the experience and efficacy of "one-stop" left atrial appendage clipping (LAAC) combined with transcatheter aortic valve replacement (TAVR) for patients with atrial fibrillation (AF) and aortic valve disease. Methods From April 2018 to March 2021, 16 patients with AF and severe aortic valve disease underwent "one-stop" LAAC and TAVR in our department. All patients had long-standing persistent AF. There were 10 males and 6 females with an average age of 77.2±6.2 years. CHA2DS2-VASc score was 4.4±0.8 points, and HAS-BLED score was 3.5±0.7 points. ResultsAll patients successfully underwent "one-stop" LAAC combined with TAVR. There was no death during perioperative and follow-up periods. The length of the left atrial appendage base measured during the operation was 37.8±3.5 mm. The types of atrial appendage clip were 35 mm (n=3), 40 mm (n=8) and 45 mm (n=5). The time required for clipping the left atrial appendage (from skin cutting to skin suturing) was 25.7±3.8 min. There was no stroke or bleeding of important organs during the perioperative period. The average hospital stay was 6.8±2.0 d. The follow-up time was 19.6±10.1 months, during which there was no patient of cerebral hemorrhage or cerebral infarction. During the administration of warfarin, 2 patients had subcutaneous ecchymosis and 1 patient had gingival bleeding. Conclusion"One-stop" LAAC combined with TAVR can be safely and effectively used to treat AF and aortic valve disease patients with high risk of thromboembolism and anticoagulant bleeding. The early and middle-term curative effect is 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.
Biological valves can lead to structural valve degeneration (SVD) over time and due to various factors, reducing their durability. SVD patients need to undergo valve replacement surgery again, while traditional open chest surgery can cause significant trauma and patients often give up treatment due to intolerance. Research has shown that as an alternative treatment option for reoperation of thoracic valve replacement surgery, redo-transcatheter aortic valve replacement for SVD is safe and effective, but still faces many challenges, including prosthesis-patient mismatch, high cross valve pressure difference, and coronary obstruction. This article aims to review the strategies, clinical research status and progress of redo-transcatheter aortic valve replacement in SVD patients.
This case was a 58-year-old female patient with patent ductus arteriosus (PDA) and severe aortic stenosis. Upon admission, she had severe heart failure and severe edema of both lower extremities unable to lie flat. After cardiac function adjustment and under general anesthesia, she underwent a one-stop operation of PDA occlusion and transcarotid transcatheter aortic valve replacement due to the severe aortic arch stenosis which brought high risk in transfemoral artery approach. Her symptoms improved significantly, and she was discharged only 6 days after operation. At the follow-up 3 months after operation, the aortic valve transvalvular pressure gradient improved significantly, the ductus arteriosus murmur disappeared, and the patient recovered well.
Patients with Takayasu arteritis combined with aortic valve disease often have a poor prognosis following surgical valve replacement, frequently encountering complications such as perivalvular leakage, valve detachment, and anastomotic aneurysm. This article presents a high-risk case wherein severe aortic valve insufficiency associated with Takayasu arteritis was successfully managed through transcatheter aortic valve implantation via the transapical approach. The patient had satisfactory valve function with no complications observed during the six-month postoperative follow-up period. This case provides a minimally invasive and feasible alternative for the clinical management of such high-risk patients.
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) for severe aortic stenosis is growing rapidly. The use of new heart valves prosthesis has improved surgical safety and efficacy. This report described a 72-year-old male patient with severe aortic stenosis combined with severe aortic regurgitation, who was evaluated at moderate-high risk of surgery and received a transapical TAVR using the Ken-Valve heart valve. The transcatheter operation time was 8 min, and the blood loss was 50 mL. The tracheal intubation was removed immediately after the surgery. Transesophageal echocardiography on the 4th postoperative day showed that the aortic valve leaflets worked well, and there was no valve orifice and paravalvular leakage. The patient was discharged on the 5th day after the surgery without complications. Transapical TAVR using Ken-Valve was an easy surgical procedure for aortic valve disease, and had short operation time.
Pre-rehabilitation is an emerging preoperative management strategy designed to mitigate surgical stress responses and expedite postoperative recovery through optimized interventions, which typically includes exercise training, nutritional support, and psychological counseling. For patients undergoing transcatheter aortic valve replacement (TAVR), the implementation of pre-rehabilitation measures is particularly crucial. This article reviews the necessity and principal components of pre-rehabilitation in TAVR patients, and offers suggestions including constructing the best pre-rehabilitation intervention program for TAVR, enhancing patient compliance and engagement in the recovery process, and paying attention to the management of frailty for TAVR patients. The aim is to provide a reference for healthcare professionals seeking to further refine the pre-rehabilitation management model for TAVR patients.
Quadricuspid aortic valve (QAV) is a rare congenital heart disease, and its long-term lesion type is mainly reflux. The application of transcatheter aortic valve replacement (TAVR) in such patients is extremely rare. This article reports a case of an elderly patient with QAV complicated with severe regurgitation and small subvalvular membrane. Through preoperative evaluation and guidance from the cardiac team discussion, a relatively high oversize rate retrievable valve was selected and the TAVR surgery was successfully completed. At the same time, the valve implantation depth was adjusted to cover the subvalvular membrane. After surgery, the patient’s symptoms such as palpitations were significantly improved. No obvious perivalvular leakage or regurgitation was observed. It provides a reference for TAVR surgical plans for such patients.
