About this study

Mitral regurgitation (MR) is a common disease and is associated with high morbidity and mortality if left untreated. Due to age and comorbidities, patients are often ineligible for surgical repair or replacement. Over the last years, transcatheter systems have been introduced as an alternative therapeutic approach. The Tendyne Mitral Valve System (Abbott Vascular, Roseville, Minnesota) is a transcatheter transapical, self-expanding valve prosthesis for mitral valve replacement. A recent study has proven safety and feasibilty of the system, leading to commercial approvement (CE mark). However, data on real world experience with the system are not available.

TENDER is a multicenter, single-device, retrospective and prospective, observational study. Objectives of the study are 1) to assess early outcomes, including safety and efficacy, in patients treated with the Tendyne Mitral Valve System for severe MR at 30 days, 2) to assess clinical outcomes in patients treated with the Tendyne Mitral Valve System for severe MR at 1 year and 3 year follow-up, and 3) to identify echocardiographic and CT-based anatomic predictors associated with outcomes.

Secondary outcomes

  1. Rate of peri-procedural myocardial infarction

    Time frame: 1 day

    Myocardial infarction during the index procedure

  2. Rate of conversion to open-heart surgery

    Time frame: 1 day

  4. Rate of procedural mortality

    Time frame: 1 day

    Death during the index procedure

  5. Rate of technical success (cumulative endpoint according to MVARC)

    Time frame: 1 day

    Absence of procedural mortality, successful access, delivery and retrieval of the delivery system, successful deployment and positioning, freedom from emergency surgery) Device success (according to MVARC): absence of procedural mortality or stroke, proper placement and positioning, freedom from unplaned procedure related to the device or access, continued safety and performance of the device (no structural or functional failure, no technical complications, reduction of MR ≤ 2+ and mitral valve gradient < 5 mmHg)

  6. Rate of device success (cumulative endpoint according to MVARC)

    Time frame: 30 days, 1 year and 3 years

    Absence of procedural mortality or stroke, proper placement and positioning, freedom from unplaned procedure related to the device or access, continued safety and performance of the device (no structural or functional failure, no technical complications, reduction of MR ≤ 2+ and mitral valve gradient < 5 mmHg)
