RESUMEN
INTRODUCTION AND OBJECTIVES: Transcatheter aortic valve implantation (TAVI) using the cusp overlap technique (COT) has shown a lower pacemaker implantation rate at 30 days. The objective of this study was to compare electrocardiogram changes and clinical outcomes between COT and the traditional technique (TT) at 1 year of follow-up. METHODS: Observational, retrospective, nonrandomized study of consecutive patients undergoing TAVI between January 2015 and January 2021. Patients were matched using a propensity score and the TT was compared with COT. The primary endpoints were electrocardiogram changes and a combined endpoint including pacemaker implantation, hospitalization, or cardiovascular death at 1 year. RESULTS: We included 254 patients. After propensity score matching, 184 patients (92 per group) remained. There were no statistically significant differences in baseline characteristics. At 1 year, COT patients showed a significant reduction in new onset left bundle branch block (49% vs 27%, P=.002) and less P wave (13.1±21.0 msec vs 5.47±12.5 msec; P=.003) and QRS prolongation (29.77±27.0 msec vs 16.38±25.4 msec, P <.001). COT was associated with a significant reduction in the occurrence of the primary endpoint (SHR, 0.39 [IC95%, 0.21-0.76]; P=.005). CONCLUSIONS: At 1 year of follow-up, COT reduced the incidence of new onset left bundle branch block and diminished QRS and P wave widening compared with the TT. COT was also associated with a statistically significant reduction in the occurrence of the combined primary cardiovascular endpoint.

OBJETIVO: Determinar la percepción de los médicos internos residentes (MIR) de cardiología de España sobre el efecto de la pandemia por COVID-19 en su formación y la adaptación realizada por sus servicios. MÉTODOS: Estudio de corte transversal a través de una plataforma de encuesta digital con el objetivo de conocer la opinión individual de los MIR de cardiología sobre la influencia de la pandemia en su formación. Se realiza un análisis estadístico para determinar los factores que influyeron en la percepción de la formación afectada. RESULTADOS: Participó un total de 180 MIR de las 17 comunidades autónomas (CA). Los MIR de tercer año fueron los más afectados, junto con los que rotaban en imagen cardíaca. Los residentes de las CA con una prevalencia >5 casos/1,000 habitantes fueron los que mayor probabilidad tuvieron de ser desplazados de sus servicios. CONCLUSIONES: Según la opinión de los participantes, el efecto de la pandemia por COVID-19 en su formación fue más negativa en los residentes de tercer año y los que rotaban en imagen cardíaca. OBJECTIVE: The objectives were to analyze the perception of the Cardiology Fellows in Training (FIT) of Spain about the impact of the COVID-19 pandemic on their academic training and to know the adaptative changes performed by their department. METHODS: A cross-sectional study performed through a digital survey platform for Cardiology FIT. Chi2 analysis and logistic regression were performed to determine the factors that influenced on the perception of an affected training. RESULTS: A total of 180 FIT from the 17 regions of Spain participated. Third year FIT and those rotating in cardiac imaging were the most affected with statistically significant difference. The residents of the regions with a prevalence of >5 cases/1,000 inhabitants were the most likely to be displaced from their departments. CONCLUSIONS: According to the opinion of the participants, the impact of the COVID-19 pandemic on their academic training was more negative in third year FITs and those rotating in cardiac imaging.

We present a case of a 40-year-old Spanish man with cardiac amyloidosis in which a Tc-99m-3,3-diphosphono-1,2-propanodicarboxylic acid (Tc-99m-DPD) scintigraphy was strongly suggestive of cardiac amyloidosis by transthyretin (ATTR) but endomyocardial biopsy (EB) analyzed by immunohistochemistry demonstrated a light chain amyloidosis (AL). Even though the Tc-99m-DPD has proven in different published papers that has high sensibility and specificity for differentiating AL and ATTR cardiac amyloidosis, we present an unusual case of an AL cardiac amyloidosis with a Perugini grade 3 on the scintigraphy. Diagnostic approach of cardiac amyloidosis following consensus documents is discussed to avoid diagnostic mistakes based on imaging techniques.
