          Abstract

          RESUMEN Introducción y objetivos: La angiografía por tomografía computarizada (angio-TC) es el estándar para medir el anillo aórtico en pacientes tratados mediante implante percutáneo de válvula aórtica (TAVI), aunque en algunos casos podría no ser factible. Debería evaluarse la precisión de las medición del anillo aórtico angiográfica (AAA) durante el TAVI como alternativa para elegir el tamaño correcto de la válvula cardiaca percutánea. Por ello, investigamos la correlación entre las mediciones angiográficas y por angio-TC para elegir el tamaño adecuado de la válvula en pacientes que reciben un TAVI. Métodos: Se incluyeron pacientes de TAVI con prótesis de balón expandible y angio-TC de alta calidad. Las mediciones del AAA se obtuvieron de la angiografía de la raíz aórtica en proyección de 3 cúspides. Se comparó la distancia angiográfica entre la cúspide izquierda y no coronariana con las mediciones de angio-TC. Se evaluaron la prueba diagnóstica y la correlación entre las medidas angiográficas y de angio-TC, así como la eficacia (éxito técnico, posición correcta y desempeño intencionado) y la seguridad (múltiples válvulas, embolización, implante de marcapasos e insuficiencia valvular moderada o mayor) definida por VARC-3. Resultados: Para válvulas con balón expandible de 23 mm, la distancia en la aortografía tuvo una correlación de 0,528 (p < 0,01) comparada con las mediciones de angio-TC; para las de 26 mm, la correlación fue de 0,451 (< 0,01), y para las de 29 mm fue de 0,579 (< 0,01). No hubo diferencia en cuanto a eficacia (94,2 frente a 96,0%; p = 0,60) y seguridad (90,9 frente a 91,9%; p = 0,84) entre casos con medidas concordantes y discordantes. Conclusiones: Las mediciones del AAA mostraron un moderado valor de prueba diagnóstica y de correlación Spearman en comparación con la angio-TC para elegir el tamaño de la válvula cardiaca percutánea. Esta estrategia podría permitir un TAVI en situaciones en que la angio-TC no esté disponible.

          ABSTRACT Introduction and objectives: Coronary computed tomography angiography (CCTA) has become the gold standard to measure the size of the aortic annulus and better select the size of transcatheter heart valves (THV) in patients undergoing transcatheter aortic valve implantation (TAVI). However, in selected cases, CCTA may not be feasible. Angiographic aortic annulus (AAA) measurements during TAVI may be an alternative and should be evaluated for precision regarding the proper selection of THV sizes. We sought to investigate the correlation between AAA and CCTA measurements for the proper selection of balloon-expandable valve (BEV) sizes in patients undergoing TAVI. Methods: Patients undergoing TAVI with BEV and high-quality CCTA were included. AAA measurements were obtained in the standard 3-cusp view after aortic root aortography. Angiographic distance between non- and left coronary cusps were compared to CCTA annulus measurements. Endpoints were diagnostic tests and correlations between angiographic and CCTA measurements, and the composite endpoint of the VARC-3-defined efficacy (technical success, correct position, and intended performance), and safety profile (multiple valves, valve embolization, pacemaker implantation, and more than moderate valvular regurgitation). Results: Regarding the Sapien family of THV, aortography-based distance measurements showed a correlation of 0.528 (P <.01), 0.451 (P <.01), and 0.579 (P <.01) for 23 mm, 26 mm, and 29 mm valves with CCTA-based distance measurements. No difference was seen regarding the VARC-3-defined efficacy (94.2% vs 96.0%; P =.60) and safety profile (90.9% vs 91.9%; P =.84) among cases showing discordant and concordant pairs of measurements. Conclusions: AAA measurement showed a moderate diagnostic test and Spearman's correlation coefficient compared to CCTA-based annulus assessment for perioperative THV size selection. This strategy could potentially enable TAVI in patients in whom access to preoperative CCTA is not available.

          Transcatheter Aortic-Valve Replacement with a Balloon-Expandable Valve in Low-Risk Patients

          Among patients with aortic stenosis who are at intermediate or high risk for death with surgery, major outcomes are similar with transcatheter aortic-valve replacement (TAVR) and surgical aortic-valve replacement. There is insufficient evidence regarding the comparison of the two procedures in patients who are at low risk.

            Transcatheter Aortic-Valve Replacement with a Self-Expanding Valve in Low-Risk Patients

            Transcatheter aortic-valve replacement (TAVR) is an alternative to surgery in patients with severe aortic stenosis who are at increased risk for death from surgery; less is known about TAVR in low-risk patients.

              Transcatheter versus surgical aortic-valve replacement in high-risk patients.

              The use of transcatheter aortic-valve replacement has been shown to reduce mortality among high-risk patients with aortic stenosis who are not candidates for surgical replacement. However, the two procedures have not been compared in a randomized trial involving high-risk patients who are still candidates for surgical replacement. At 25 centers, we randomly assigned 699 high-risk patients with severe aortic stenosis to undergo either transcatheter aortic-valve replacement with a balloon-expandable bovine pericardial valve (either a transfemoral or a transapical approach) or surgical replacement. The primary end point was death from any cause at 1 year. The primary hypothesis was that transcatheter replacement is not inferior to surgical replacement. The rates of death from any cause were 3.4% in the transcatheter group and 6.5% in the surgical group at 30 days (P=0.07) and 24.2% and 26.8%, respectively, at 1 year (P=0.44), a reduction of 2.6 percentage points in the transcatheter group (upper limit of the 95% confidence interval, 3.0 percentage points; predefined margin, 7.5 percentage points; P=0.001 for noninferiority). The rates of major stroke were 3.8% in the transcatheter group and 2.1% in the surgical group at 30 days (P=0.20) and 5.1% and 2.4%, respectively, at 1 year (P=0.07). At 30 days, major vascular complications were significantly more frequent with transcatheter replacement (11.0% vs. 3.2%, P<0.001); adverse events that were more frequent after surgical replacement included major bleeding (9.3% vs. 19.5%, P<0.001) and new-onset atrial fibrillation (8.6% vs. 16.0%, P=0.006). More patients undergoing transcatheter replacement had an improvement in symptoms at 30 days, but by 1 year, there was not a significant between-group difference. In high-risk patients with severe aortic stenosis, transcatheter and surgical procedures for aortic-valve replacement were associated with similar rates of survival at 1 year, although there were important differences in periprocedural risks.
