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.
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.
Severe symptomatic native aortic regurgitation (AR) is associated with poor prognosis. Surgical aortic valve replacement is presently the main choice of treatment according to current guidelines. The data of safety and efficacy of transcatheter aortic valve replacement (TAVR) for patients with pure native AR were limited. In this paper, a case of AR patient with heart failure was reported. After preoperative CT evaluation and operation plan, the postoperative symptoms improved significantly. Bundle branch block and retroperitoneal hematoma appeared during hospitalization. After the treatment, the patient’s condition improved. Before the discharge, cardiac ultrasound indicated that the reflux was significantly improved, no perivalvular leakage was observed, and cardiac function was improved. AR remains a challenging pathology for TAVR. TAVR is a feasible and reasonable option for carefully selected patients with pure AR.
ObjectiveTo summarize the clinical result of a combined technical system for bicuspid aortic valve (BAV) repair. MethodsPatients who diagnosed as BAV and sever aortic regurgitation (AR) underwent a strategy of combined repair technics including annuloplasty, sinus plasty, leaflet plasty, sinus-tubular junction (STJ) plasty depending on anatomy pathological characteristics between October 2019 and January 2021 were enrolled. The clinical data of the patients were analyzed.ResultsA total of 17 patients were enrolled. There were 11 males and 6 females with an average age of 18-49 (32.4±13.6) years. Fifteen patients had typeⅠand 2 patients had typeⅡBAV according to Sievers classification. Annuloplasty was applicated in 13 patients, sinus plasty in 8 patients, leaflet plasty in 17 patients, and STJ plasty in 11 patients, respectively. The cardiopulmonary bypass (CPB) time was 95 (84, 135) min, aortic cross-clamping time was 68 (57, 112) min, and the ICU stay time was 17 (12, 25) h. After the operation, mild AR was presented in 14 patients, moderate AR in 1 patient and severe AR in 2 patients. The latter 3 patients underwent second operation under CPB, after then, 1 patient had mild AR and 2 patients had moderate AR. The follow-up time was 13.1±4.6 months. At the latest follow-up, 12 patients had mild AR and 5 patients had moderate AR, and no patient had reoperation. ConclusionA combined technical system for BAV repair can be used effectively and safely with an acceptable short and middle-term result.
Takayasu arteritis (TA) is a primary, chronic, non-specific, inflammatory disease of the aorta and its larger branches. The pulmonary artery trunk and its branches could be impacted by TA, which could cause stenosis or occlusion of lesion vessels. TA also affects the normal function of the aortic valve and other heart valves, mainly due to valvular insufficiency. Aortic regurgitation caused by TA is mainly treated by surgical operation. In this review, the examination technique, operation timing, operation method and prognosis of aortic valve involved in TA are discussed systematically.
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.
Transcatheter aortic valve implantation (TAVI) is an important alternative in treating high-risk patients with aortic valve regurgitation. Transcatheter tricuspid valve implantation (TTVI) is also an important treatment option for high-risk patients with tricuspid regurgitation. We reported a 72-year male patient who underwent TAVI due to severe aortic valve regurgitation using a J-Valve. During a two-year follow-up, the patient developed secondary tricuspid regurgitation to atrial fibrillation, and subsequently received TTVI using a LuX-Valve. Following the interventions, the patient's symptoms were significantly improved, and echocardiography indicated good hemodynamic performance of both transcatheter heart valves. This case highlights the feasibility and effectiveness of performing multiple valve implantations via transcatheter approaches in high-risk elderly patients.
Objective To investigate the early safety and efficacy of transapical transcatheter aortic valve implantation (TAVI) for high-risk elderly patients with pure aortic valve insufficiency. Methods A prospective multicenter clinical study of domestic J-valveTM TAVI for high-risk native non-calcified aortic valve insufficiency was conducted from April 2014 to May 2018, and the early postoperative results were analyzed. A total of 82 patients were enrolled, including 62 patients from West China Hospital, Sichuan University, 16 patients from Zhongshan Hospital, Fudan University, and 4 patients from Beijing Fuwai Hospital, National Center for Cardiovascular Diseases. There were 55 males and 27 females. The age was 61-90 (73.8±6.3) years. The logistic EuroSCORE was 10.0%-44.4% (17.5%±8.1%). All patients underwent TAVI using J-ValveTM system. Clinical evaluation and echocardiography were performed preoperatively and 1 month postoperatively. Multislice spiral CT was reviewed before discharge. Results Three patients were transferred to thoracotomy for cardiopulmonary bypass operation, and 1 patient had decreased cardiac function due to leakage of the valve 1 week after surgery. The overall technical and procedural success rate was 95.1% and 93.9%, respectively. During hospitalization, 1 patient died of moderate pericyclosis complicated with multiple organ failure, and 1 patient died of pulmonary infection. Six (7.6%) patients received pacemaker implantation due to new onset Ⅲ° atrioventricular block. Echocardiographic follow-up showed paravalvular leak was observed in the few of patients, mild paravalvular leak was in 13 patients on the 30th day. Two patients showed moderate paravalvular leak. Left ventricular end-diastolic volume decreased from 197.7±66.8 mL (pre-TAVI) to 147.2±53.3 mL (30-day post-TAVI) (P<0.05). Mean pressure gradient was 9.5±4.1 mm Hg (30-day post-TAVI). Conclusion This multicenter study demonstrates that TAVI with the J-Valve system for the treatment of pure aortic regurgitation is associated with sustained clinical and functional cardiovascular benefits in high-risk patients with symptomatic aortic regurgitation early-term follow-up. Our results further support that TAVI with the specific designed J-Valve system is an acceptable alternative therapy for high-risk patients with pure AR. Our result demonstrates good early-term durability and preserved hemodynamic function. The procedure appears to offer an adequate and lasting resolution for selected patients with pure aortic regurgitation.
Transcatheter aortic valve replacement (TAVR) techniques have been rapidly developed in recent years. Current guidelines and studies mainly focus on aortic stenosis patients treated by transfemoral approach, but they are not completely appropriate to patients with isolated aortic regurgitation or other patients who need transapical TAVR (TA-TAVR), which affects the standardized treatment of those patients. Therefore, our team pronounced the operational standards for TA-TAVR, based on fully reviewing the literatures worldwide, combined with the opinions of experts from 15 heart centers with rich experience in carrying out TA-TAVR in China. This standard aims to provide clinicians with standardized diagnosis and treatment principles of TA-TAVR and improve the quality of TA-TAVR in China.
