Early clinical outcomes after transaxillary versus transfemoral TAVI. Data from the Spanish TAVI registry.

INTRODUCTION AND OBJECTIVES: Transaxillary access (TXA) has become the most widely used alternative to transfemoral access (TFA) in patients undergoing transcatheter aortic valve implantation (TAVI). The aim of this study was to compare total in-hospital and 30-day mortality in patients included in the Spanish TAVI registry who were treated by TXA or TFA access. METHODS: We analyzed data from patients treated with TXA or TFA and who were included in the TAVI Spanish registry. In-hospital and 30-day events were defined according to the recommendations of the Valve Academic Research Consortium. The impact of the access route was evaluated by propensity score matching according to clinical and echocardiogram characteristics. RESULTS: A total of 6603 patients were included; 191 (2.9%) were treated via TXA and 6412 via TFA access. After adjustment (n=113 TXA group and n=3035 TFA group) device success was similar between the 2 groups (94%, TXA vs 95%, TFA; P=.95). However, compared with the TFA group, the TXA group showed a higher rate of acute myocardial infarction (OR, 5.3; 95%CI, 2.0-13.8); P=.001), renal complications (OR, 2.3; 95%CI, 1.3-4.1; P=.003), and pacemaker implantation (OR, 1.6; 95%CI, 1.01-2.6; P=.03). The TXA group also had higher in-hospital and 30-day mortality rates (OR, 2.2; 95%CI, 1.04-4.6; P=.039 and OR, 2.3; 95%CI, 1.2-4.5; P=.01, respectively). CONCLUSIONS: Compared with ATF, TXA is associated with higher total mortality, both in-hospital and at 30 days. Given these results, we believe that TXA should be considered only in those patients who are not suitable candidates for TFA.

Prognostic value of SYNTAX score and SYNTAX score II in an 'all-comers' population treated with angoplasty.

OBJECTIVES: The SYNTAX score and SYNTAX score II have a high predictive capacity for adverse cardiovascular events. We aimed to demonstrate that both scores were good predictors of long-term adverse outcomes in an 'all-comers' population treated with a percutaneous coronary intervention (PCI). METHODS: In the study, we included 785 patients who received an angioplasty at our center between January 2011 and December 2012. The patients were distributed in tertiles according to the SYNTAX score and SYNTAX score II values; for the SYNTAX score - low ≤6.5 (n = 225); mid >6.5, <11.5 (n = 229); high ≥11.5 (n = 221); and for the SYNTAX score II PCI: low ≤20.5 (n = 226); mid >20.5, < 29.6 (n = 221); and high ≥29.6 (n = 218). RESULTS: The rates of major adverse cardiovascular events, death, cardiac death and new revascularizations at 3 years were significantly higher in the highest tertile of both the scores. For SYNTAX score: major adverse cardiovascular events, 12-15.3-21.7%, P < 0.001; death, 7.6-8.3-14%, P = 0.04; cardiac death, 3.2-2.7-7.5%, P = 0.03; new revascularizations, 4.5-8.6-10.4%, P = 0.001. For SYNTAX score II PCI: major adverse cardiovascular events, 8-10.9-28.9%, P < 0.001; death, 3.1-3.6-21.5%, P < 0.001; cardiac death, 0.9-0.5-11.4%, P < 0.001; new revascularizations, 4.5-8.2-11.3%, P = 0.03. CONCLUSION: The SYNTAX score II showed better predictive capacity than the SYNTAX score for major adverse cardiovascular events, death and cardiac death, with no difference noted for new revascularizations, and it was an independent predictor for these events in an 'all-comers' population.

Evaluación prospectiva del desarrollo de nefropatía inducida por contraste en pacientes con síndrome coronario agudo tratados con angiografía coronaria rotacional vs. angiografía coronaria convencional: Estudio CINERAMA / Prospective evaluation of the development of contrast-induced nephropathy in patients with acute coronary syndrome undergoing rotational coronary angiography vs. conventional coronary angiography: CINERAMA study

Introducción y objetivos: La angiografía coronaria rotacional (ACR) permite reducir la cantidad de contraste administrado y puede prevenir el desarrollo de nefropatía inducida por contraste (NIC) durante los procedimientos coronarios invasivos. El objetivo del estudio es evaluar el impacto de la ACR en la aparición de NIC (aumento de creatinina ≥0,5mg/dL o ≥25%) tras un síndrome coronario agudo. Métodos: De abril a septiembre de 2016 se seleccionaron prospectivamente pacientes con síndrome coronario agudo remitidos para coronariografía diagnóstica con posibilidad de angioplastia ad hoc, que fueron estudiados con ACR o angiografía coronaria convencional (ACC) según criterio del operador. Se compararon la NIC (variable de valoración primaria), variables analíticas, angiográficas y clínicas. Resultados: De 235 pacientes reclutados, 116 pacientes fueron estudiados con ACR y 119 pacientes con ACC. El grupo de ACR presentaba mayor edad (64,0±11,8 vs. 59,7±12,1 años; p=0,006), más mujeres (44,8 vs. 17,6%; p<0,001) y peor filtrado glomerular estimado (76±25 vs. 86±27 mL/min/1,73 m2; p=0,001), con menos angioplastias (p<0,001). Asimismo, el grupo de ACR recibió menos contraste (113±92 vs. 169±103 mL; p<0,001), diferencias que se mantuvieron en los procedimientos diagnósticos (54±24 vs. 85±56 mL; p<0,001) y diagnóstico-terapéuticos (174±64 vs. 205±98 mL; p=0,049). El grupo de ACR presentó menos NIC (4,3 vs. 22,7%; p<0,001): en el análisis de regresión se objetivó que continuaba relacionándose con menor desarrollo de NIC (riesgo relativo ajustado: 0,868; IC 95%: 0,794-0,949; p=0,002). No hubo diferencias en las variables clínicas. Conclusiones: La ACR se asoció con menor administración de contraste durante procedimientos coronarios invasivos tras un síndrome coronario agudo, lo que resultó en una menor aparición de NIC (AU)

Introduction and objectives: Rotational coronary angiography (RCA) requires less contrast to be administered and can prevent the onset of contrast-induced nephropathy (CIN) during invasive coronary procedures. The aim of the study is to evaluate the impact of RCA on CIN (increase in serum creatinine ≥0.5mg/dl or ≥25%) after an acute coronary syndrome. Methods: From April to September 2016, patients suffering acute coronary syndromes who underwent diagnostic coronary angiography, with the possibility of ad hoc coronary angioplasty, were prospectively enrolled. At the operator's discretion, patients underwent RCA or conventional coronary angiography (CCA). CIN (primary endpoint), as well as analytical, angiographic and clinical endpoints, were compared between groups. Results: Of the 235 patients enrolled, 116 patients received RCA and 119 patients received CCA. The RCA group was composed of older patients (64.0±11.8 years vs. 59.7±12.1 years; p=0.006), a higher proportion of women (44.8 vs. 17.6%; p<0.001), patients with a lower estimated glomerular filtration rate (76±25 vs. 86±27ml/min/1.73 m2; p=0.001), and patients who underwent fewer coronary angioplasties (p<0.001) compared with the CCA group. Furthermore, the RCA group, received less contrast (113±92 vs. 169±103ml; p<0.001), including in diagnostic procedures (54±24 vs. 85±56ml; p<0.001) and diagnostic-therapeutic procedures (174±64 vs. 205±98ml; p=0.049) compared with the CCA group. The RCA group presented less CIN (4.3 vs. 22.7%; p<0.001) compared to the CCA group, and this finding was maintained in the regression analysis (Adjusted relative risk: 0.868; 95% CI: 0.794-0.949; p=0.002). There were no differences in clinical endpoints between the groups. Conclusions: RCA was associated with lower administration of contrast during invasive coronary procedures in acute coronary syndrome patients, resulting in lower incidence of CIN, in comparison with CCA (AU)
