Details and patient eligibility

About

The study will evaluate the efficacy and safety of transcatheter aortic valve implantation (TAVI) using the Hydra transcatheter aortic heart valve (THV) series, in patients with severe aortic stenosis up to 1-year after the procedure. This will include an evaluation of the preservation of coronary access post implant by attempting to selectively engage both the right and left coronary arteries through standardised angiographic views.

The study will also examine the utility of 72 hours of post discharge remote ambulatory continuous electrocardiogram (ECG) monitoring using the novel Checkpoint Cardio System where it is clinically appropriate.

Full description

This is a prospective, observational, multi-centre study. The aim of this study is to collect clinical, procedural, and follow-up data in order to evaluate the efficacy and safety of the Hydra THV series (Vascular Innovations Co. Ltd., Nonthaburi, Thailand).

Additionally, the study will conduct the following evaluation:

  1. The remote ambulatory cardiac monitoring (rACM) using the Checkpoint Cardio System, consisting of 72 hours of continuous electrocardiogram (ECG) monitoring, will be evaluated post hospital discharge where it is clinically appropriate.
  2. Coronary access will be evaluated immediately post-TAVI by attempting to selectively engage both the right and left coronary arteries through standardised angiographic views. This will be done in a sub-set of patients who are either known to have coronary artery disease, did not have coronary angiogram prior to TAVI or where it is felt to be clinically appropriate for other reasons post implant.

Following discharge, clinical follow-ups are scheduled at 45 days (±14 days), and 1-year (±30 days).
