postoperative AF

Łukasz Lewicki, Janusz Siebert, Jan Rogowski
BACKGROUND: Postoperative atrial fibrillation (AF) is a common arrhythmia that occurs after coronary artery bypass grafting (CABG). New surgical techniques, particularly off-pump coronary artery bypass (OPCAB), are thought to be less invasive and results in fewer complications, i.e. AF, but available data are inconsistent. The aim of this study is to present the incidence and risk factors of AF in patients operated on with or without cardiopulmonary bypass. METHODS: We studied 1836 consecutive patients with stable coronary artery disease who were operated on with (CABG) or without (OPCAB) cardiopulmonary bypass...

OBJECTIVE: Atrial fibrillation is the most common arrhythmia after cardiac surgery. Several studies have shown the impact of vitamin D on heart disease; however, there have been few studies for the incidence of AF and its relationship with vitamin D levels. According to the different results of these studies, we decided to evaluate the relation of plasma levels of vitamin D and postoperative atrial fibrillation in patients undergoing coronary artery bypass surgery (CABG). METHODS: This cross-sectional study was performed on 50 patients after CABG surgery...

At the end of cardiopulmonary bypass, there are invariably several hundred millilitres of residual pump blood in the reservoir, which can either be re-transfused or discarded. The objective of this prospective observational study was to investigate the quality of the residual pump blood, focusing on plasma free haemoglobin (pfHb) and blood cell counts. Fifty-one consecutive patients were included in the study. Forty-nine units of residual pump blood and 58 units of transfused red blood cell (RBC) concentrates were analysed...

BACKGROUND: Deficiency of vitamin D is known to be effective in the development of hypertension, coronary artery disease, myocardial infarction, and stroke. Deficiency of vitamin D was also shown to be associated with new onset atrial fibrillation (AF) by activating the renin-angiotensin system. This study investigated whether or not levels of vitamin D are effective in the development of AF after coronary artery bypass grafting (CABG) surgery. METHODS: A total of 283 patients undergoing CABG were included in this study...

BACKGROUND: Glioblastoma patients show a great variability in progression free survival (PFS) and overall survival (OS). To gain additional pretherapeutic information, we explored the potential of O-(2-(18)F-fluoroethyl)-L-tyrosine (FET) PET as an independent prognostic biomarker. METHODS: We retrospectively analyzed 146 consecutively treated, newly diagnosed glioblastoma patients. All patients were treated with temozolomide and radiation therapy (RT). CT/MR and FET PET scans were obtained postoperatively for RT planning...

OBJECTIVES: To determine the effectiveness of a simplified surgical treatment method for atrial fibrillation (AF). METHODS: Between September 2012 and October 2013, 120 patients (mean age, 52.3 ± 8.8 years) underwent valve surgery and concomitant bipolar radiofrequency ablation for the treatment of AF. Patients were randomized to a Cox maze IV procedure (CMP-IV) group (n = 60) or a modified CMP-IV (MCMP-IV) group (n = 60). Freedom from AF was defined as freedom from any left atrial arrhythmia lasting <30 s and no requirement of antiarrhythmic drugs after 6 months...

We present the case of a 55-year-old male with mild hypertension and brief episodes of paroxysmal self-limiting atrial fibrillation (AF) since 2010. Despite a small cardioembolic risk score, CHA2DS2-Vasc=1 (Congestive heart failure, Hypertension, Age=75, Diabetes melitus, prior Stroke), the patient is effectively anticoagulated using acenocumarol. In December 2014, he showed signs of plantar transitory ischemia, for which he did not address the doctor. In early January 2015, he urgently presented at the hospital with left renal pain, caused by a renal infarction, diagnosed by computed tomography (CT) angiography...

OBJECTIVE: Atrial fibrillation (AF) is the most common arrhythmia following coronary artery by-pass graft surgery (CABG). The value of SYNTAX score to predict postoperative atrial fibrillation (PoAF) has not been clearly addressed. We aimed to evaluate this relationship in patients undergoing isolated CABG. METHODS: This study was designed as a single-center, non-randomized, observational, prospective study. Ninety-four patients undergoing isolated on-pump CABG, who had sinus rhythm and were older than 18 years, were enrolled...

INTRODUCTION: Atrial fibrillation (AF) is one of the most frequent complications occurring after thoracic surgery especially after lung resection. It is associated with an increase in postoperative morbidity and mortality. Recent data having documented the preventive role of corticosteroids on the occurrence of AF in cardiac surgery, we sought to evaluate the effect of preoperative administration of dexamethasone on the incidence of AF after pneumonectomy. METHODS: We reviewed the files of all consecutive patients who underwent a pneumonectomy in one single centre between July 2004 and July 2012...
