    Abstract La técnica de mapeo endocárdico durante el estudio electrofisiológico ha sido extensamente empleada en el análisis de las taquicardias paroxísticas supraventriculares (TPS). Mediante este mapeo endocárdico y el análisis meticuloso de los electrogramas endocárdicos y los respectivos intervalos de conducción, es posible localizar el sitio de origen de las arritmias y así facilitar su tratamiento ablativo por medio de catéteres de radiofrecuencia. Se describe el caso de un hombre de 29 años con síndrome de Wolff-Parkinson-White (WPW) que manifiestó que presentaba varios episodios documentados de TPS con serio compromiso hemodinámico que motivaba su frecuente internación en terapia intensiva. El mapeo electrofisiológico endocárdico meticuloso demostró la presencia de un haz anómalo de Kent auriculoventricular izquierdo en posición posteroseptal. El período refractario absoluto del haz anómalo de Kent fue de 240 ms. La primera emisión de radiofrecuencia a través de un catéter adecuadamente posicionado previo terminó la taquicardia. La taquicardia permaneció no inducible a partir de entonces. En estas dos décadas de seguimiento clínico, el paciente no ha presentado ni un solo episodio de taquicardia. La curación definitiva generada por la ablación del haz anómalo de Kent ha proporcionado un cambio drástico, total y beneficioso en la calidad de vida al paciente. Los beneficios clínicos y socioeconómicos son mayores cuanto más temprano en la evolución se realice el procedimiento de ablación de arritmias.

  7. Article ; Online: Vulnerabilidad intrínseca del miocardio auricular como mecanismo de génesis de fibrilación auricular en el síndrome de Wolff-Parkinson-White

    Abstract Los investigadores que describieron por primera vez el síndrome de Wolff-Parkinson-White (WPW) ya reconocieron la existencia de una asociación de ésta entidad con la fibrilación auricular (FA). Se han documentado episodios de FA hasta en un 30% de los pacientes con síndrome de WPW. Diversas modificaciones histológicas y electrofisiológicas del miocardio auricular, tales como, cambios fibrodegenerativos, aumento en la dispersión de los períodos refractarios, retardo en la conducción de los impulsos, conducción anisotrópica, e interacción con el sistema nervioso autonómico, se encuentran asociadas a la inducción, generación y persistencia de la FA. Mediante la estimulación auricular programada con extraestímulo simple durante el estudio electrofisiológico se pueden inducir varios parámetros de vulnerabilidad auricular aumentada. Por ejemplo, la actividad auricular repetitiva, la actividad auricular fragmentada, y el retardo en la conducción interauricular inducidos por un extraestímulo temprano en diástole en pacientes que poseen anormalidades electrofisiológicas del miocardio auricular, han sido utilizados como indicadores de vulnerabilidad auricular y como requisitos importantes para la génesis de la reentrada, y por ende, de la FA. Los pacientes con síndrome de WPW y FA paroxística poseen un número significativamente mayor de electrogramas auriculares anormalmente fragmentados y prolongados y una anormalidad electrofisiológica del músculo auricular significativamente mayor que los pacientes con síndrome de WPW sin FA paroxística. Estos resultados claramente demuestran que el miocardio auricular patológico y la vulnerabilidad intrínseca del miocardio auricular juegan un papel muy importante en el desarrollo de la FA en pacientes con el síndrome de WPW.

    Abstract Background: Left atrial peak systolic strain (LA-PSS) imaging is an emerging index of LA function, and it was shown to be decreased in heart failure with preserved ejection fraction. We aimed to determine whether LA-PSS could be used as an additional diagnostic parameter to current existing guidelines for the presence of left ventricle diastolic dysfunction (LVDD).
    Materials and methods: A total of 190 consecutive adult patients with cardiovascular risk factors and normal LV ejection fraction with no prior history of heart failure were included in the study. Speckle tracking software was used to study ventricular parietal deformity, left ventricle global longitudinal systolic strain (LV-GLS), and LA-PSS.
    Results: The median LV-GLS was -19%, with a significant difference (p<0.001) between patients with normal diastolic function vs those with LVDD. The median LA-PSS was 33% (30 to 38%) (p<0.001). Most patients (61%) had grade 1 atrial dysfunction based on PSS (range 24% to 35%). The analysis of the area under the ROC curve of the LA-PSS as a potential indicator pathway of LVDD was 67% (95% CI 62-72), and 75% (95% CI 70-80), when the indeterminate pattern was included. The decreased LA-PSS made it possible to reclassify patients with an indeterminate pattern of diastolic function in 96% of cases.
    Conclusion: These results support the potential role of LA-PSS as an additional parameter for the diagnosis of LVDD in patients with normal ejection fraction, and may be integrated into the guidelines for routine evaluation of patients.

    Abstract Despite the beneficial effects of anti-COVID-19 vaccination, monitoring its safety has identified potential cardiac adverse events, mainly myocarditis and pericarditis. The case of a healthy 32-year-old male patient who developed acute myocardial infarction (AMI) 48 hours after the second dose of anti-COVID-19 mRNA vaccine (BNT162b2) is reported. This is the first reported case in the literature of an AMI associated to post-COVID-19 vaccination with mRNA vaccine (BNT162b2) in a healthy young adult without coronary risk factors and normal coronary arteries. Despite this adverse event, the continuation of the anti-COVID-19 vaccination campaign is encouraged due to the benefits it brings.
