Tricuspid Structural Valve Deterioration Treated with a Transcatheter Valve-in-Valve Implantation: A Single-Center Prospective Registry.

ABSTRACT: The valve-in-valve (ViV) technique is an emerging alternative for the treatment of bioprosthetic structural valve deterioration (SVD) in the tricuspid position. We report on the outcomes of patients treated by a transcatheter tricuspid valve-in-valve (TT-ViV) implantation for symptomatic SVD in the tricuspid position during the years 2010-2019 at our center. Three main outcomes were examined during the follow-up period: TT-ViV hemodynamic data per echocardiography, mortality and NYHA functional class. Our cohort consisted of 12 patients with a mean age 65.4 ± 11.9 years, 83.3% male. The mean time from initial valve intervention to TT-ViV was 17.4 ± 8.7 years. The indications for TT-ViV were varied (41.7% for predominant regurgitation, 33.3% for predominant stenosis and 25.0% with a mixed pathology). All patients were treated with a balloon-expandable device. The mean follow-up was 3.4 ± 1.3 years. Tricuspid regurgitation was ≥ moderate in 57.2% of patients prior to the procedure and this decreased to 0% following the procedure. The mean transtricuspid valve gradients mildly decreased from the mean pre-procedural values of 9.0 mmHg to 7.0 mmHg at one month following the procedure (p = 0.36). Mortality at one year was 8.0% (95% CI 0-23). At the baseline, 4 patients (33.3%) were in NYHA functional class III/IV; this was reduced to 2 patients (18.2%) at the one year follow-up and both were in NYHA III. The TT-ViV procedure offered a safe, feasible and less invasive treatment option for patients with SVD in our detailed cohort.

Project description:ImportanceThe frequency and clinical importance of structural valve deterioration (SVD) in patients undergoing self-expanding transcatheter aortic valve implantation (TAVI) or surgery is poorly understood.ObjectiveTo evaluate the 5-year incidence, clinical outcomes, and predictors of hemodynamic SVD in patients undergoing self-expanding TAVI or surgery.Design, setting, and participantsThis post hoc analysis pooled data from the CoreValve US High Risk Pivotal (n = 615) and SURTAVI (n = 1484) randomized clinical trials (RCTs); it was supplemented by the CoreValve Extreme Risk Pivotal trial (n = 485) and CoreValve Continued Access Study (n = 2178). Patients with severe aortic valve stenosis deemed to be at intermediate or increased risk of 30-day surgical mortality were included. Data were collected from December 2010 to June 2016, and data were analyzed from December 2021 to October 2022.InterventionsPatients were randomized to self-expanding TAVI or surgery in the RCTs or underwent self-expanding TAVI for clinical indications in the nonrandomized studies.Main outcomes and measuresThe primary end point was the incidence of SVD through 5 years (from the RCTs). Factors associated with SVD and its association with clinical outcomes were evaluated for the pooled RCT and non-RCT population. SVD was defined as (1) an increase in mean gradient of 10 mm Hg or greater from discharge or at 30 days to last echocardiography with a final mean gradient of 20 mm Hg or greater or (2) new-onset moderate or severe intraprosthetic aortic regurgitation or an increase of 1 grade or more.ResultsOf 4762 included patients, 2605 (54.7%) were male, and the mean (SD) age was 82.1 (7.4) years. A total of 2099 RCT patients, including 1128 who received TAVI and 971 who received surgery, and 2663 non-RCT patients who received TAVI were included. The cumulative incidence of SVD treating death as a competing risk was lower in patients undergoing TAVI than surgery (TAVI, 2.20%; surgery, 4.38%; hazard ratio [HR], 0.46; 95% CI, 0.27-0.78; P = .004). This lower risk was most pronounced in patients with smaller annuli (23 mm diameter or smaller; TAVI, 1.32%; surgery, 5.84%; HR, 0.21; 95% CI, 0.06-0.73; P = .02). SVD was associated with increased 5-year all-cause mortality (HR, 2.03; 95% CI, 1.46-2.82; P < .001), cardiovascular mortality (HR, 1.86; 95% CI, 1.20-2.90; P = .006), and valve disease or worsening heart failure hospitalizations (HR, 2.17; 95% CI, 1.23-3.84; P = .008). Predictors of SVD were developed from multivariate analysis.Conclusions and relevanceThis study found a lower rate of SVD in patients undergoing self-expanding TAVI vs surgery at 5 years. Doppler echocardiography was a valuable tool to detect SVD, which was associated with worse clinical outcomes.Trial registrationClinicalTrials.gov Identifiers: NCT01240902, NCT01586910, and NCT01531374.
