ABSTRACT

ABSTRACT Although technically simple, surgical correction of patent ductus arteriosus can have serious complications. In this context, acute ventricular failure must be remembered, as its prompt diagnosis and proper management can change clinical outcomes.

ABSTRACT

Abstract Ascending aortic aneurysm is usually associated with aortic valve diseases, especially aortic stenosis. The standard technique involves the substitution of the dilated aortic segment with a Dacron tube and replacement of the aortic valve with a regular prosthesis. The correction of ascending aortic aneurysm with aortic valve replacement using the new sutureless and rapid deployment prosthesis was performed by a minimally invasive approach and for the first time in a Brazilian Center.

ABSTRACT

Background: Left ventricular (LV) diastolic dysfunction is associated with new-onset atrial fibrillation (AF), and the estimation of elevated LV filling pressures by E/e' ratio is related to worse outcomes in patients with AF. However, it is unknown if restoring sinus rhythm reverses this process. Objective: To evaluate the impact of AF ablation on estimated LV filling pressure. Methods: A total of 141 patients underwent radiofrequency (RF) ablation to treat drug-refractory AF. Transthoracic echocardiography was performed 30 days before and 12 months after ablation. LV functional parameters, left atrial volume index (LAVind), and transmitral pulsed and mitral annulus tissue Doppler (e' and E/e') were assessed. Paroxysmal AF was present in 18 patients, persistent AF was present in 102 patients, and long-standing persistent AF in 21 patients. Follow-up included electrocardiographic examination and 24-h Holter monitoring at 3, 6, and 12 months after ablation. Results: One hundred seventeen patients (82.9%) were free of AF during the follow-up (average, 18 ± 5 months). LAVind reduced in the successful group (30.2 mL/m2 ± 10.6 mL/m2 to 22.6 mL/m2 ± 1.1 mL/m2, p < 0.001) compared to the non-successful group (37.7 mL/m2 ± 14.3 mL/m2 to 37.5 mL/m2 ± 14.5 mL/m2, p = ns). Improvement of LV filling pressure assessed by a reduction in the E/e' ratio was observed only after successful ablation (11.5 ± 4.5 vs. 7.1 ± 3.7, p < 0.001) but not in patients with recurrent AF (12.7 ± 4.4 vs. 12 ± 3.3, p = ns). The success rate was lower in the long-standing persistent AF patient group (57% vs. 87%, p = 0.001). Conclusion: Successful AF ablation is associated with LA reverse remodeling and an improvement in LV filling pressure. .


Fundamento: A disfunção diastólica do ventrículo esquerdo (VE) está associada a novos episódios de fibrilação atrial (FA), e a estimativa das pressões de enchimento do VE através da razão E/e' está relacionada a um pior prognóstico em pacientes com FA. Entretanto, não se sabe se a restauração do ritmo sinusal pode reverter este processo. Objetivo: Avaliar o impacto da ablação da FA na estimativa da pressão de enchimento do VE. Métodos: Um total de 141 pacientes foi submetido à ablação por radiofrequência (RF) para o tratamento da FA refratária a drogas. Foi realizado ecocardiograma transtorácico 30 dias antes e 12 meses após a ablação. Foram avaliados os parâmetros funcionais do VE, volume do átrio esquerdo indexado (VAEi) e Doppler transmitral pulsado e Doppler tecidual do anel mitral (e' e E/e'). Dezoito pacientes apresentavam FA paroxística, 102 persistente e 21 pacientes FA persistente de longa duração. O acompanhamento incluiu ECG e monitoramento pelo sistema Holter 24h, 3, 6 e 12 meses após a ablação. Resultados: Cento e dezessete pacientes (82,9%) não apresentaram FA durante o acompanhamento (média de 18 meses ± 5 meses). O VAEi apresentou redução significativa no grupo com sucesso (30,2 mL/m2 ± 10,6 mL/m2 para 22,6 mL/m2 ± 1,1 mL/m2, p < 0,001) em comparação ao grupo sem sucesso (37,7 mL/m2 ± 14,3 mL/m2 para 37,5 mL/m2 ± 14,5 mL/m2, p = ns). A melhora da estimativa da pressão de enchimento do VE, avaliada através da redução na razão E/e', foi observada apenas após ablação com sucesso (11,5 ± 4,5 vs. 7,1 ± 3,7, p < 0,001), não sendo observada em pacientes com FA recorrente (12,7 ± 4,4 vs. 12 ± 3,3, p = ns). A taxa de ...

ABSTRACT

Fístulas das artérias coronárias têm incidência baixa entre as cardiopatias congênitas, muitas vezes assintomáticas, devendo ser suspeitadas quando há presença de sopro contínuo no precórdio. Podem apresentar sintomas de precordialgia ou insuficiência cardíaca e devem ser estudadas adequadamente para tratamento seguro, tanto cirúrgico como por cateterismo ou acompanhamento clínico. No presente trabalho são relatados três casos tratados por operação com resultado satisfatório e a literatura é revisada
