Life beyond 5 Years after TAVI: Patients' Perceived Health Status and Long-Term Outcome after Transcatheter Aortic Valve Implantation.

ABSTRACT: Background:Transcatheter aortic valve implantation (TAVI) is currently recommended for patients with severe aortic stenosis at intermediate or high surgical risk. The decision process during TAVI evaluation includes a thorough benefit-risk assessment, and knowledge about long-term benefits and outcomes may improve patients' expectation management. Objective:To evaluate patients' perceived health status and self-reported long-term outcome more than 5 years after TAVI. Methods and Results:Demographic and procedure data were obtained from all patients treated with TAVI at our institution from 2006 to 2012. A cross-sectional survey was conducted on the patients alive, measuring health status, including the EQ-5D-5L questionnaire, and clinical outcomes. 103 patients (22.8%) were alive at a median follow-up period of 7 years (5.4-9.8). 99 (96%) of the 103 patients were included in the final analysis. The mean age at follow-up was 86.5 years ± 8.0 years, and 56.6% were female. Almost all patients (93.9%) described an improvement of their quality of life after receiving TAVI. At late follow-up, the mean utility index and EQ-VAS score were 0.80 ± 0.20 and 58.49 ± 11.49, respectively. Mobility was found to be the most frequently reported limitation (85.4%), while anxiety/depression was the least frequently reported limitation (19.8%). With respect to functional class, 64.7% were in New York Heart Association (NYHA) class III or IV, compared to 67.0% prior to TAVI (p=0.51). Self-reported long-term outcomes revealed mainly low long-term complication rates. 74 total hospitalizations were reported after TAVI, and among those 43% for cardiovascular reasons. Within cardiovascular rehospitalizations, new pacemaker implantations were the most frequently reported (18.9%), followed by cardiac decompensation and coronary heart disease (15.6%). Conclusion:The majority of the patients described an improvement of health status after TAVI. More than five years after TAVI, the patients' perceived health status was satisfactory, and the incidence of clinical events and hospitalizations was very low.

Project description:BACKGROUND:Transcatheter aortic valve implantation/replacement (TAVI/TAVR) is becoming more frequently used to treat aortic stenosis (AS), with increasing push for the procedure in lower risk patients. Numerous randomized controlled trials have demonstrated that TAVI offers a suitable alternative to the current gold standard of surgical aortic valve replacement (SAVR) in terms of short-term outcomes. The present review evaluates long-term outcomes following TAVI procedures. METHODS:Literature search using three electronic databases was performed up to June 2017. Studies which included 20 or more patients undergoing TAVI procedures, either as a stand-alone or concomitant procedure and with a follow-up of at least 5 years, were included in the present review. Literature search and data extraction were performed by two independent researchers. Digitized survival data were extracted from Kaplan-Meier curves in order to re-create the original patient data using an iterative algorithm and subsequently aggregated for analysis. RESULTS:Thirty-one studies were included in the present analysis, with a total of 13,857 patients. Two studies were national registries, eight were multi-institutional collaborations and the remainder were institutional series. Overall, 45.7% of patients were male, with mean age of 81.5±7.0 years. Where reported, the mean Logistic EuroSCORE (LES) was 22.1±13.7 and the mean Society of Thoracic Surgeons (STS) score was 9.2±6.6. The pooled analysis found 30-day mortality, cerebrovascular accidents, acute kidney injury (AKI) and requirement for permanent pacemaker (PPM) implantation to be 8.4%, 2.8%, 14.4%, and 13.4%, respectively. Aggregated survival at 1-, 2-, 3-, 5- and 7-year were 83%, 75%, 65%, 48% and 28%, respectively. CONCLUSIONS:The present systematic review identified acceptable long-term survival results for TAVI procedures in an elderly population. Extended follow-up is required to assess long-term outcomes following TAVI, particularly before its application is extended into wider population groups.

Project description:BackgroundIn the treatment of valvular heart diseases, transcatheter therapies have changed the rules of the game, especially in the case of aortic stenosis and mitral regurgitation. Since the first in man transcatheter aortic valve intervention (TAVI) performed by Dr. Alain Cribier in 2002 in a non-operable aortic stenosis (AS) patient, TAVI has changed the lives of so many patients for whom medical treatment was, up to then, the only option.ObjectiveThis article outlines patient selection and pre-procedure evaluation, current perspectives, recent advances, current and future devices, current guidelines informing the use of TAVI, expanding indications for TAVI, ongoing challenges and the future of TAVI.MethodsThe use of these percutaneous techniques has also increased significantly in the past few years with its first application in 2002, transcatheter aortic valve implantation (TAVI) has revolutionized the management of aortic stenosis and has become the standard of care for patients with AS at prohibitively high surgical risks, as well as a preferred treatment for elderly patients with intermediate and high-risk AS.ResultsSince the first pioneering procedure was performed 22 years ago, transcatheter aortic valve implantation (TAVI) has evolved into a routine procedure increasingly performed under conscious sedation via transfemoral access. On a global market worth $2 billion per year, over 300 000 patients have received a transcatheter aortic valve, demonstrating its clinical and market impact. TAVI may be used in lower risk, younger, asymptomatic populations with ongoing studies using an expanding portfolio of devices. Also, for patients deemed unsuitable for cardiac surgery, mitral transcatheter therapies represent the treatment of choice. Percutaneous repair techniques have had the most clinical experience to date.ConclusionDuring this 20-year period, the increased knowledge on pre-procedural planning, the important technological improvements in transcatheter valves, the increased experience and the numerous studies that have been carried out have permitted an expansion of the indications for TAVI, from inoperable patients to high- and intermediate-risk patients. This article outlines patient selection and pre-procedure evaluation, current perspectives, recent advances, current and future devices, current guidelines informing the use of TAVI, expanding indications for TAVI, ongoing challenges and the future of TAVI.
