First-in-Human Percutaneous Circumferential Annuloplasty for Secondary Tricuspid Regurgitation.

ABSTRACT: Transcatheter therapies to treat tricuspid regurgitation are being developed, but few have attempted the gold standard of surgical repair: ring annuloplasty. We describe the first-ever fully percutaneous implantation of a circumferential, semirigid annuloplasty ring to treat massive secondary tricuspid regurgitation. (Level of Difficulty: Advanced.).

Project description:BackgroundTo identify the association between tricuspid annular circumference and secondary tricuspid regurgitation and analyze the risk factors of recurrent tricuspid regurgitation after concomitant tricuspid annuloplasty during left heart surgery.MethodsFrom October 2018 to June 2019, a total of 117 patients receiving concomitant tricuspid annuloplasty within left heart surgery were enrolled. Severity of tricuspid regurgitation was classified as 4 subtypes: normal, mild, moderate and severe. Perioperative data and mid-term outcome were collected. Tricuspid annular circumference (TAC) was measured under cardiac arrest during surgery procedure by cardioplegia. Optimal TAC and TAC index (TAC/body surface area, BSA) cutoffs of significant tricuspid annulus dilatation (moderate and severe) were obtained. Univariable and multivariable logistic regression analyses were performed to identify the risk factors of postoperative recurrent tricuspid regurgitation. The follow up period is 13-19 months (mean 15.5 ± 3.2 months).ResultsThere was 1 patient was excluded who died after surgery. A total of 116 patients receiving tricuspid annuloplasty were included. Optimal cutoffs of significant tricuspid annulus dilatation were recommended (TAC 11.45 cm, Sensitivity 82.89%, Specificity 73.68%, AUC 0.915; TAC index 7.09 cm/m2, Sensitivity 73.68%, Specificity 85%, AUC 0.825, respectively). Based on findings of multivariable logistic regression, it has been showed that TAC index and postoperative atrial fibrillation were the independent risk factors of recurrent regurgitation after surgery. Optimal TAC index cutoff to predict recurrent tricuspid regurgitation was 7.86 cm/m2 CONCLUSIONS: The severity of secondary tricuspid regurgitation is associated with the tricuspid annular circumference. The cut-offs of significant tricuspid regurgitation (more than moderate) were TAC 11.45 cm and TAC index 7.09 cm/m2, respectively. Clinically, concomitant tricuspid annuloplasty is relative safe and effective. TAC index ≥ 7.86 cm/m2 and postoperative atrial fibrillation are the risk factors of recurrent significant tricuspid regurgitation after concomitant tricuspid annuloplasty during left heart surgery.

Project description:BackgroundWhile tricuspid annuloplasty (TAP) is an effective treatment option for tricuspid regurgitation (TR), understanding the echocardiographic factors contributing to recurrent TR can help in developing more effective preventive measures to reduce the rate of recurrent TR after TAP.MethodsThis study was designed as a prospective observational cohort study to investigate factors contributing to recurrent TR following surgical tricuspid valve (TV) repair in patients with moderate or severe functional TR caused by left heart valvular disease, with severe mitral regurgitation as the dominant pathology. The study included 66 patients who underwent preoperative two-dimensional (2D) and three-dimensional (3D) echocardiographic assessments. Patients were divided into two groups based on TAP outcomes: the effective TAP group and the recurrent TR group.ResultsThe analysis revealed that 3D-derived both septal-lateral diastolic and systolic tricuspid annulus (TA) diameter (odds ratio (OR) 1.77; 95% confidence interval (CI) 1.17-2.68 and OR 1.62; 95% CI 1.14-2.29, respectively), and major axis diastolic TA diameter (OR 1.59; 95% CI 1.15-2.2) had the highest OR among all echocardiographic parameters. The further univariate analysis of predefined echocardiographic values unveiled that the combined effect of heightened 3D-measured TA major axis diastolic diameter and increased right ventricle (RV) basal diameter exhibited the highest OR at 12.8 (95% CI 2.3-72.8) for a recurrent TR. Using ROC analysis, diastolic major axis (area under the curve (AUC) 0.848; cut-off 48.5 mm), septal-lateral systolic (AUC 0.840; cut-off 43.5 mm) and diastolic (AUC 0.840; cut-off 46.5 mm) TA diameter demonstrated the highest predictive value for recurrent TR from all TV parameters.ConclusionsRecurrent moderate or severe TR after TAP is associated with preoperative TA size, right atrium and RV geometry, but not with changes of RV function. The predictive capacity of 2D-assessed echocardiographic parameters was found to be lower when compared to their corresponding 3D parameters.
