TRanscatheter Aortic-Valve Implantation With or Without On-site Cardiac Surgery: the TRACS Trial

N/AActive Not RecruitingNCT05751577

Azienda Usl di Bologna657 enrolled

Overview

The primary efficacy objective is to determine whether a TAVI procedure performed by experienced operators in centers without on-site cardiac surgery is noninferior to TAVI procedure performed by the same operators in centers with on-site cardiac surgery in terms of all-cause death, stroke and rehospitalization for cardiovascular cause. The primary safety objective is to demonstrate that mortality associated with periprocedural complications actionable by emergent cardiac surgery did not differ between study arms.

TRACS is an all-comer, prospective, randomized, multicenter, open-label trial with blinded adjudicated evaluation of outcomes (PROBE). The TRACS trial will involve centers without on-site cardiac surgery, but with experienced operators already performing TAVI at the referring center with on-site cardiac surgery. Thus, participating centers and their study TAVI operators must follow selective criteria for eligibility. Participants will be recruited after Heart Team indication to TAVI procedure. The eligibility of each single patient to the study MUST BE CONFIRMED and VALIDATED by unanimous decision of the Heart Team. Study patients will be randomized in a 2:1 fashion to TAVI procedure performed by the same experienced operators either in the center without on-site cardiac surgery or in the referring center with on-site cardiac surgery.

Conditions

Aortic Stenosis, Severe

Interventions

TAVI WITHOUT ON-SITE SURGERYPROCEDURE

After randomization, study TAVI operators of the participating center will schedule the patient for TAVI in their hospital without on-site surgery

TAVI WITH ON-SITE SURGERYPROCEDURE

After randomization, the patient will immediately be placed on the waiting list of the referring center with on-site cardiac surgery. Study TAVI operators of the participating center will perform the TAVI procedure in the hospital with on-site surgery according to the waiting list schedule of the latter

Outcomes

Primary Outcomes

Primary efficacy endpoint

1-year cumulative occurrence of all-cause death, stroke and hospital readmission for CV cause To test if the outcome of TAVI procedures performed by experienced operators in the center without onsite cardiac surgery is non inferior to that of TAVI procedures performed by the same team in the center with on-site cardiac surgery

Time frame: 1-year

Primary safety endpoint

To test whether mortality due to periprocedural complications actionable by emergent cardiac surgery differs between the TAVI procedures performed in the center without on-site cardiac surgery and the TAVI procedures performed by the same team in the center with on-site cardiac surgery

Time frame: 1-year

Secondary Outcomes

Secondary efficacy endpoints

All-cause death Cardiovascular death Myocardial infarction Hospital admission for cardiovascular cause Hospital admission for heart failure Cerebrovascular accident Ischemic stroke Hospital admission for pneumonia (± respiratory failure) Need for balloon aortic valvuloplasty for emergent condition Quality of life measured with the Eq-5D and KCCQ-12 scales Time spent on the waiting list before TAVI

Time frame: 1-year

Other safety endpoints
