Effects of different levels of end-expiratory pressure on hemodynamic, respiratory mechanics and systemic stress response during laparoscopic cholecystectomy

Rev. bras. anestesiol; 67 (1), 2017
Abstract Objective: General anesthesia causes reduction of functional residual capacity. And this decrease can lead to atelectasis and intrapulmonary shunting in the lung. In this study we want to evaluate the effects of 5 and 10 cmH2O PEEP levels on gas exchange, hemodynamic, respiratory mechanics and ...

Evaluation of anomalous coronary arteries from the pulmonary artery

Abstract Objective: This study evaluated clinical and diagnostic findings, treatment methods, and follow-up of cases of anomalous coronary arteries from the pulmonary artery. Methods: The study included all cases diagnosed with anomalous coronary arteries from the pulmonary artery between January 2012 ...

Bovine pericardial patch augmentation of one insufficient aortic valve cusp with twenty-three-year positive clinical follow-up independent of the patch degeneration

Abstract Scientific progress shall ultimately boost the current acceptance level for conservative aortic valve surgery. The present text aimed to report the 23-year long-term follow-up of one patient operated with bovine pericardium cusp extension. Growing confidence in the efficacy of the operation will...

Electrical approach to improve left ventricular activation during right ventricle stimulation

Medicina (B.Aires); 77 (1), 2017
Coronary sinus mapping is commonly used to evaluate left atrial activation. Herein, we propose to use it to assess which right ventricular pacing modality produces the shortest left ventricular activation times (R-LVtime) and the narrowest QRS widths. Three study groups were defined: 54 controls without ...

Quem São os Super-Respondedores à Terapia de Ressincronização Cardíaca?

Fundamento: Pacientes submetidos à ressincronização cardíaca podem evoluir com padrões de resposta acima do esperado, com normalização dos parâmetros clínicos e ecocardiográficos. Objetivo: Analisar as características clínicas e ecocardiográficas desta população de super-respondedores, com...

Múltiplas causas de síncope em pacientes com distrofia miotônica tipo I

A distrofia miotônica é a doença neuromuscular mais frequente na população adulta. Embora tenha caráter multissistêmico, apresenta especial predileção pelo sistema de condução cardíaco, manifestando-se tanto com bloqueios atrioventriculares como com taquiarritmias ventriculares e supraventri...

Electrocardiogram Performance in the Diagnosis of Left Ventricular Hypertrophy in Hypertensive Patients With Left Bundle Branch Block

Arq. bras. cardiol; 108 (1), 2017
Abstract Background: Left ventricular hypertrophy (LVH) is an important risk factor for cardiovascular events, and its detection usually begins with an electrocardiogram (ECG). Objective: To evaluate the impact of complete left bundle branch block (CLBBB) in hypertensive patients in the diagnostic perf...

Variabilidade da frequência cardíaca com a mudança postural na insuficiência cardíaca crônica

Introdução: A variabilidade da frequência cardíaca (VFC) é uma alternativa de baixo custo para a avaliação da modulação autonômica cardíaca que é relacionada com os indivíduos com insuficiência cardíaca (IC) crônica devido ao desequilíbrio simpático-vagal característico dessa patologia...

Compound Heterozygous SCN5A Mutations in a Toddler - Are they Associated with a More Severe Phenotype?

Arq. bras. cardiol; 108 (1), 2017
Abstract Compound heterozygosity has been described in inherited arrhythmias, and usually associated with a more severe phenotype. Reports of this occurrence in Brugada syndrome patients are still rare. We report a study of genotype-phenotype correlation after the identification of new variants by geneti...

Fatores preditores para boa resposta à terapia de ressincronização cardíaca: critérios práticos para o clínico

A terapia de ressincronização cardíaca é uma alternativa eficaz em pacientes com insuficiência cardíaca e dessincronia, podendo reduzir significativamente a morbimortalidade. Apesar de haver indicações bem estabelecidas, cerca de um terço dos pacientes não responde à terapia; assim, a busca po...
