ABSTRACT
Resumen: El 34° Congreso Uruguayo de Cardiología, celebrado en Montevideo del 2 al 4 de diciembre del pasado año, nuevamente destacó por las excelentes presentaciones de los temas más relevantes del ámbito cardiológico, así como también por sus invitados de renombre, nacionales e internacionales. Acompañando el gran nivel del Congreso se expusieron 32 temas libres que abarcaron diferentes áreas de la cardiología de los cuales comentaremos cuatro trabajos premiados: - Riesgo de trombosis en bioprótesis aórtica y eventos clínicos según uso de anticoagulación. Metaanálisis de la evidencia actual. - Uso de NT-ProBNP como predictor de evolución en el posoperatorio de cirugía cardíaca. - Prevalencia de septal pouch en una cohorte derivada para ecocardiograma transesofágico. - Incidencia de troponina T ultrasensible en rango anormal y su correlación con la anatomía coronaria en pacientes en valoración por enfermedad coronaria estable.
Summary: The 34th Uruguayan Congress of Cardiology, celebrated last year in Montevideo from December 2nd to 4th, again stood out for the excellent presentations of the most relevant topics in the field of cardiology, as well as for its renowned national and international guests. Accompanying the great level of the Congress, 32 articles that covered different topics in the cardiological area were presented, of which we will comment four awarded: - Risk of thrombosis in aortic bioprosthesis and clinical events according to the use of anticoagulation. Meta-analysis of current evidence. - Use of NT-ProBNP as a predictor of evolution in the postoperative period of cardiac surgery. - Prevalence of septal pouch in a cohort derived for transesophageal echocardiography. - Incidence of ultrasensitive troponin T in abnormal range and its correlation with coronary anatomy in patients in assessment for stable coronary disease.
Resumo: O 34º Congresso Uruguaio de Cardiologia, realizado em Montevidéu entre os dias 2 e 4 de dezembro no ano passado, voltou a destacar-se pelas excelentes apresentações dos temas mais relevantes no campo da cardiologia, bem como por seus renomados convidados, nacionais e internacionais. Acompanhando o grande nível do Congresso, tinham 32 temas livres que cobriam diferentes áreas da cardiologia, dos quais comentaremos quatro artigos premiados: - Risco de trombose na bioprótese aórtica e eventos clínicos de acordo com o uso de anticoagulação. Meta-análise da evidência atual. - Uso de NT-ProBNP como preditor de evolução no pós-operatório de cirurgia cardíaca. - Prevalência de bolsa septal em uma coorte derivada para ecocardiografia transesofágica. - Incidência de troponina T ultrassensível em faixa anormal e sua correlação com a anatomia coronariana em pacientes em avaliação para doença coronariana estável.
ABSTRACT
Purpose: To determine the prevalence of Left Atrial Septal Pouch (LASP) and assess the association with Patent Foramen Ovale (PFO). Materials and Methods: We retrospectively reviewed 275 cardiac-gated CT examinations at Indiana University from January 2010 to June 2012, 160 cardiac CTs performed prior to pulmonary vein ablation, 115 for evaluation of coronary artery evaluation. Consensus readings were performed by two readers on a PACS workstation using the Multiplanar Reformat software to identify the presence or absence of LASP and PFO. PFO was diagnosed by the presence of a contrast jet extending from the left atrium to the right atrium. Results: Overall prevalence of LASP was 24.7% (68 LASPs out of 275 patients). There was no significant difference regarding the gender and age between patients with and without LASP, pvalues 0.054 and 0.63 respectively. The overall prevalence of PFO in both groups is low 2.2% (6 PFOs out of 275 patients). The prevalence of PFO in patients with LASP was 5.9% (4 out of 68 patients) and was 1.0% (2 PFOs out of 207 patients) in patients without LASP. There was a significant difference in prevalence of PFO between patients with and without LASP, p-value 0.035. Conclusions: LASP is a common finding on cardiac CT, its prevalence not affected by age or gender. Patients with LASP have statistically greater prevalence of PFO than patients without LASP, but the prevalence remains low.
