Remote Ischemic Preconditioning Neither Improves Survival nor Reduces Myocardial or Kidney Injury in Patients Undergoing Transcatheter Aortic Valve Implantation (TAVI).

ABSTRACT: BACKGROUND:Peri-interventional myocardial injury occurs frequently during transcatheter aortic valve implantation (TAVI). We assessed the effect of remote ischemic preconditioning (RIPC) on myocardial injury, acute kidney injury (AKIN) and 6-month mortality in patients undergoing TAVI. METHODS:We performed a prospective single-center controlled trial. Sixty-six patients treated with RIPC prior to TAVI were enrolled in the study and were matched to a control group by propensity-score. RIPC was applied to the upper extremity using a conventional tourniquet. Myocardial injury was assessed using high-sensitive troponin-T (hsTnT), and kidney injury was assessed using serum creatinine levels. Data were compared with the Wilcoxon-Rank and McNemar tests. Mortality was analysed with the log-rank test. RESULTS:TAVI led to a significant rise of hsTnT across all patients (p < 0.001). No significant inter-group difference in maximum troponin release or areas-under-the-curve was detected. Medtronic CoreValve and Edwards Sapien valves showed similar peri-interventional troponin kinetics and patients receiving neither valve did benefit from RIPC. AKIN occurred in one RIPC patient and four non-RIPC patients (p = 0.250). No significant difference in 6-month mortality was observed. No adverse events related to RIPC were recorded. CONCLUSION:Our data do not show a beneficial role of RIPC in TAVI patients for cardio- or renoprotection, or improved survival.

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.
