CT-derived simulations to predict outcomes in patients undergoing transcatheter aortic valve implantation with an ACURATE Neo2 valve the PRECISE-TAVI cohort B trial.
Background: Paravalvular leakage (PVL) and conduction disorders that require permanent pacemaker implantation (PPI) remain clinically relevant challenges after transcatheter aortic valve implantation (TAVI). Computed tomography-based simulations may predict the risk of significant PVL and PPI.
Aims: To evaluate the feasibility and accuracy of preprocedural computer simulation with FEops HEARTguide™ to predict >trace PVL and PPI after TAVI with the self-expanding supra-annular ACURATE Neo2 transcatheter heart valve.
Methods: Prospective multicenter observational study that included consecutive patients undergoing TAVI with an ACURATE Neo2 valve. Computer simulations were performed before the TAVI procedure as part of the preprocedural planning. Follow-up period for PPI and PVL was 30 days.
Results: Sixty-five patients were included (median age 81 years (25th-75th percentile 77-84.5)). New left bundle branch block occurred in five patients (7.7%) and PPI in two patients (3%). Contact pressure index (CPI) was similar for patients with vs without new conduction disorders. Patients with PPI had numerically higher CPI than those without PPI (median CPI 20.0% (25th-75th percentile 15.0-25.0) vs. 13.0% (25th-75th percentile 5.5-18), p = 0.27). More than trace PVL occurred in 30%. Median PVL was significantly lower in patients with none-trace PVL (3.2 mL/s [25th-75th percentile 2.2-5.0]), compared to mild PVL (5.2 mL/s [25th-75th percentile 3.2-10.3]) and moderate PVL (12.6 mL/s [25th-75th percentile 3.9-21.3])(p = 0.036). A simulated PVL-cutoff of 9.65 mL/s identified patients with >trace PVL (AUC 0.70 (95% CI 0.55-0.85), sensitivity 42%, specificity 95%).
Conclusion: In our study FEops HEARTguide™ simulations identified patients at risk for >trace PVL with ACURATE Neo2 TAVI but not for PPI.
期刊介绍：
Catheterization and Cardiovascular Interventions is an international journal covering the broad field of cardiovascular diseases. Subject material includes basic and clinical information that is derived from or related to invasive and interventional coronary or peripheral vascular techniques. The journal focuses on material that will be of immediate practical value to physicians providing patient care in the clinical laboratory setting. To accomplish this, the journal publishes Preliminary Reports and Work In Progress articles that complement the traditional Original Studies, Case Reports, and Comprehensive Reviews. Perspective and insight concerning controversial subjects and evolving technologies are provided regularly through Editorial Commentaries furnished by members of the Editorial Board and other experts. Articles are subject to double-blind peer review and complete editorial evaluation prior to any decision regarding acceptability.
