Postoperative atrial fibrilation

Kang An, Hang Yin, Ju Mei, Jiaquan Zhu, Min Tang
OBJECTIVES: We retrospectively analysed data from non-valvular atrial fibrillation (AF) patients who underwent minimally invasive surgical AF ablation at our centre. Our purpose was to explore the atrial endocardial expression of von Willebrand factor (vWF) and thrombomodulin (TM) and their association with rhythm results after the procedure. METHODS: From January 2014 to May 2015, 60 patients underwent minimally invasive surgical AF ablation at our centre. Left atrial appendage samples were obtained during the procedure and immunohistochemistry for endocardial markers including vWF and TM was performed and semi-quantitatively graded...

OBJECTIVES: Minimally invasive aortic valve replacement (MIAVR) can be technically demanding and may lead to prolonged operative time. We evaluated the intraoperative and postoperative patient outcomes following implementation of 2 facilitating technologies (FT) in MIAVR: the Cor-Knot titanium fastener and Custodiol-histidine-tryptophan-ketoglutarate solution. METHODS: A total of 299 patients underwent MIAVR from 2008 to 2016; 172 (57.5%) patients were included in the FT group and 127 (42...

Background: Cognitive decline has been reported following cardiac surgery, leading to great interest in interventions to minimize its occurrence. Long-chain n-3 (ω-3) polyunsaturated fatty acids (PUFAs) have been associated with less cognitive decline in observational studies, yet no trials have tested the effects of n-3 PUFAs on cognitive decline after surgery. Objective: We sought to determine whether perioperative n-3 PUFA supplementation reduces postoperative cognitive decline in patients postcardiac surgery...

BACKGROUND: Patients with obstructive sleep apnea (OSA) experience intermittent hypoxia, hypercarbia, and sympathetic activation during sleep, which increases risk for paroxysmal atrial fibrillation and other cardiac arrhythmias. Whether patients with OSA experience increased episodes of atrial fibrillation after cardiac surgery is unclear. We examined whether patients at increased risk for OSA, assessed by the STOP-BANG (snoring, tired during the day, observed stop breathing during sleep, high blood pressure, body mass index more than 35 kg/m, age more than 50 years, neck circumference more than 40 cm, and male gender) questionnaire, had a higher incidence of new-onset postoperative atrial fibrillation after cardiac surgery...

BACKGROUND: Early postoperative atrial fibrillation (EPoAF) is associated with thromboembolic events, prolonged hospitalization, and development of late PoAF (LPoAF). It is, however, unknown if EPoAF can be predicted by intraoperative AF inducibility. The aims of this study are therefore to explore (1) the value of intraoperative inducibility of AF for development of both EPoAF and LPoAF and (2) the predictive value of de novo EPoAF for recurrence of LPoAF. METHODS AND RESULTS: Patients (N=496, 75% male) undergoing cardiothoracic surgery for coronary and/or valvular heart disease were included...

PURPOSE: Cardiac surgery and conventional extracorporeal circulation (CECC) impair the bioavailability of drugs administered by mouth. It is not known whether miniaturized ECC (MECC) or off-pump surgery (OPCAB) affect the bioavailability in similar manner. We evaluated the metoprolol bioavailability in patients undergoing CABG surgery with CECC, MECC, or having OPCAB. METHODS: Thirty patients, ten in each group, aged 44-79 years, scheduled for CABG surgery were administered 50 mg metoprolol by mouth on the preoperative day at 8-10 a...

BACKGROUND: Right ventricular (RV) dysfunction after pulmonary resection in the early postoperative period is documented by reduced RV ejection fraction and increased RV end-diastolic volume index. Supraventricular arrhythmia, particularly atrial fibrillation, is common after pulmonary resection. RV assessment can be done by non-invasive methods and/or invasive approaches such as right cardiac catheterization. Incorporation of a rapid response thermistor to pulmonary artery catheter permits continuous measurements of cardiac output, right ventricular ejection fraction, and right ventricular end-diastolic volume...

Although preoperative atrial fibrillation (AF) is common in patients undergoing continuous-flow left ventricular assist device (CF-LVAD) implantation, how AF affects outcomes remains unclear. We analyzed our single-center experience with CF-LVAD implantation to determine whether preoperative AF was associated with inferior outcomes. From November 2003 through March 2016, 526 patients with chronic heart failure underwent implantation with the HeartMate II (HMII; n = 403) or HeartWare VAD (HVAD; n = 123). We identified 229 patients (165 HMII, 65 HVAD) who had preoperative AF and compared them with non-preoperative AF patients regarding the incidence of postoperative stroke, as well as long-term survival...

This study sought to determine the incidence, predictors, and outcomes of postoperative atrial fibrillation (POAF) in patients undergoing implantation of left ventricular assist devices (LVADs). A retrospective analysis of all patients who underwent LVAD implantation from 2013 to 2014 was conducted. Postoperative AF, survival, and thrombotic complications were evaluated after surgery. A total of 47 patients (mean age, 56.4 ± 12.5 years; 33 male) were included and followed for a median of 331 days. Within 30 days of surgery, 13 (28%) patients developed POAF at mean 7...

OBJECTIVES: Postoperative atrial fibrillation (POAF) is a common complication after coronary artery bypass grafting. Although transient, POAF is linked to increased late mortality. We hypothesized that POAF increases late cerebrovascular (CeV) and composite cerebrovascular/cardiovascular/vascular (CV* = CeV + CV + Other-V) but not non-cardiovascular (Non-CV) mortality. METHODS: We analysed 8807 non-salvage coronary artery bypass grafting patients (1994-2011)...

BACKGROUND: Our previous study reported a modified endoscopic procedure for nonvalvular atrial fibrillation (AF) that requires only 3 ports in the left chest wall. HYPOTHESIS: Certain preoperative variables might be predictive risk factors for AF recurrence among patients who underwent this procedure. METHODS: From October 2010 to April 2014, 114 patients with either paroxysmal AF (PAF) or nonparoxysmal AF (non-PAF) underwent the procedure and completed postoperative cardiac-rhythm measurement via electrocardiography and Holter monitoring...

BACKGROUND: Although post-operative atrial fibrillation is common after non-cardiac surgery, there is a paucity of data regarding prophylaxis. We sought to determine if pharmacologic prophylaxis reduces the incidence of post-operative atrial fibrillation after non-cardiac surgery. METHODS: We performed an electronic search of Ovid MEDLINE, the Cochrane central register of controlled trials database, and SCOPUS from inception to 9/7/2016 and included prospective randomized studies in which patients in sinus rhythm underwent non-cardiac surgery and examined the incidence of post-operative atrial fibrillation as well as secondary safety outcomes...

Intravenous landiolol [Rapibloc® (EU)], an ultra short-acting highly cardioselective β1 -blocker, is approved in the EU for the rapid short-term control of tachyarrhythmias in the perioperative and intensive care settings. It has long been used in Japan to treat perioperative tachyarrhythmias. The efficacy of landiolol has been demonstrated in a large number of randomized controlled clinical trials. Landiolol significantly reduced heart rate in patients with postoperative or intraoperative supraventricular tachycardia relative to placebo and in those with atrial fibrillation/flutter and left ventricular dysfunction relative to digoxin...
