Self-expanding TAVI using the cusp overlap technique versus the traditional technique: electrocardiogram changes and 1-year cardiovascular outcomes.

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.

Small bowel cavernous hemangioma as an uncommon cause of iron-deficiency anemia.

Small bowel hemangiomas are benign congenital vascular lesions that can be asymptomatic or cause anemia, gastrointestinal bleeding, obstruction, or intestinal perforation. We report the case of a 75-year-old woman who, after years of study for iron-deficiency anemia, was diagnosed with a cavernous hemangioma of the jejunum by capsule endoscopy, which was confirmed after surgical resection.

Una anomalía coronaria poco común como posible causa de taquicardia ventricular / A rare coronary anomaly as a possible cause of ventricular tachycardia

Resumen Se presenta el caso de un varón de 77 años que acude a urgencias tras un episodio sincopal en el contexto de una taquicardia ventricular monomorfa sostenida, por lo que se realizó cardioversión eléctrica. Para filiar la etiología del evento arrítmico ventricular se realizó un estudio de la anatomía coronaria mediante coronariografía invasiva, en el que se objetivaron las arterias coronarias sin lesiones significativas, pero como hallazgo casual se describió una anomalía coronaria, con ausencia de tronco coronario y salida independiente de las arterias circunfleja (Cx) y descendente anterior (DA) del seno coronario derecho, originándose la DA y la coronaria derecha del mismo ostium coronario. Dichos hallazgos se confirmaron mediante tomografía computarizada con reconstrucción tridimensional. Además, se objetivó un trayecto interarterial de la DA (entre las arterias aorta y pulmonar) y un trayecto intramuscular de la DA, así como un trayecto retroaórtico de la Cx. Debido a estos hallazgos, se procedió al implante de un desfibrilador automático implantable como prevención secundaria. El paciente tuvo una buena evolución posterior y fue dado de alta a su domicilio sin incidencias. Se presenta el caso para ayudar a comprender mejor estos trastornos, dado que actualmente constituyen un reto diagnóstico, ya que en muchas ocasiones se trata de un hallazgo casual en pruebas complementarias o incluso en autopsias. Además, es una causa relativamente frecuente de parada cardiorrespiratoria en pacientes jóvenes. De las muchas variables anatómicas que constituyen las anomalías coronarias, existe poca literatura sobre esta anomalía presentada y no hay imágenes similares a las de este caso.

Abstract We present the case of a 77-year-old man who came to the emergency room after a syncopal episode in the context of sustained monomorphic ventricular tachycardia for which electrical cardioversion was performed. In order to determine the etiology of the ventricular arrhythmic event, a study of the coronary anatomy was carried out using invasive coronary angiography, observing coronary arteries without significant lesions, although, as a chance finding, a coronary anomaly was described, with absence of the main coronary artery, with independent exit of circumflex (Cx) and anterior descending (AD) arteries of the right coronary sinus, originating the AD and right coronary artery from the same coronary ostium. These findings were later confirmed by computed tomography with 3D reconstruction. In addition, an interarterial path of AD (between aorta and pulmonary artery) and an intramuscular path of AD were observed, as well as a retro-aortic path of Cx. Given these findings, an implantable cardioverter defibrillator was implanted as secondary prevention. Good subsequent evolution with home discharge without incident. We present this case to help better understand these disorders, since they currently constitute a diagnostic challenge, since in many cases it is a chance finding in complementary tests or even in autopsies. It is also a relatively frequent cause of cardiorespiratory arrest in young patients. Of the many anatomical variables that make up the group of coronary anomalies, there is little bibliographic information on this anomaly presented, without finding images similar to those reported in this case.

Endoscopic diagnosis of primary aortoesophageal fistula: An extremely rare cause of acute upper gastrointestinal bleeding.

Primary aortoesophageal fistula, an abnormal communication between native aorta and oesophagus, is an extremely rare cause of upper gastrointestinal bleeding. The typical symptoms, known as the Chiari´s triad, are only present in 45% of cases. It has a high mortality, so early diagnosis is essential to increase the probability of survival. We present a case report of a patient with massive upper gastrointestinal bleeding due to primary aortoesophageal fistula.

Impact of COVID-19 pandemic on cardiology fellows academic training: beyond the clinical impact.

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.

Unusual high 99mTc-3,3-diphosphono-1,2-propanodicarboxylic acid (99mTc-DPD) tracer deposition on a heart scintigraphy in a patient with AL amyloidosis: A case report.

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.
