Remodeling of ipsilateral ulnar artery after radial artery harvesting for coronary artery bypass graft.

There are controversies in the literature on the blood supply to the forearm after surgical removal of the radial artery in coronary artery bypass grafting (CABG). The objective was to investigate the arterial remodeling of the ulnar artery after the removal of the radial artery in myocardial revascularization by means of ultrasound examination with color Doppler in the pre- and post-operative periods. This paper describes an observational prospective study of the remodeling of the left brachial and ulnar arteries (donor arm) in 103 right-handed non-consecutive adult patients undergoing CABG with removal of the ipsilateral radial artery using the color Doppler ultrasound examination.

Cardioprotective Solutions Exposure For 1 Hour in Hypoxia and Low Temperatures Affects Vascular Reactivity Differently.

Introduction: Heart preservation benefits cardiac performance after operations decreasing morbidity but the contribution of the vascular reactivity has been neglected.

Methods: We evaluated whether cardioprotective solutions, Krebs-Henseleit (KH), Bretschneider-HTK (BHTK), St. Thomas No.

Assessment and clinical relevance of the dynamic parameters of ventricular repolarization in patients with grade I left ventricular diastolic dysfunction .

Imbalance in ventricular repolarization parameters are related to increased risk of severe arrhythmia and sudden cardiac death. There is limited research regarding markers to detect patients at risk in this early stage. We aimed to assess the influence of grade I left ventricular diastolic dysfunction on repolarization parameters in asymptomatic patients.

Treatment of Chronic Atrial Fibrillation During Surgery for Rheumatic Mitral Valve Disease.

Introduction: The result of surgical ablation of atrial fibrillation remains controversial, although prospective and randomized studies have shown significant differences in the return to sinus rhythm in patients treated with ablation versus control group. Surgery of the Labyrinth, proposed by Cox and colleagues, is complex and increases the morbidity rate. Therefore, studies are needed to confirm the impact on clinical outcomes and quality of life of these patients.

Comparative experimental study of myocardial protection with crystalloid solutions for heart transplantation.

Background: There is a growing need to improve myocardial protection, which will lead to better performance of cardiac operations and reduce morbidity and mortality. Therefore, the objective of this study was to compare the efficacy of myocardial protection solution using both intracellular and extracellular crystalloid type regarding the performance of the electrical conduction system, left ventricular contractility and edema, after being subjected to ischemic arrest and reperfusion.

Methods: Hearts isolated from male Wistar (n=32) rats were prepared using Langendorff method and randomly divided equally into four groups according the cardioprotective solutions used Krebs-Henseleit-Buffer (KHB), Bretschneider-HTK (HTK), St.

Crossed papillopexy with graft in mitral valve replacement: case report.

The aim of this study is to present the crossed papillopexy technique using bovine pericardial graft in mitral replacement caused by intense valvar and subvalvar fibrosis and calcification. This technique allows the functional preservation of the mitral subvalvar apparatus and was successfully applied, by the first time as far as we known, in a patient with calcified rheumatic mitral stenosis, who underwent mitral valve replacement surgery. The patient had an uneventful recovery and was discharged home on postoperative day 6.
