OBJECTIVE: The Cox-Maze IV procedure has been shown to be an effective treatment for atrial fibrillation when performed concomitantly with other operations either via median sternotomy or right minithoracotomy. Few studies have compared these approaches in patients with lone atrial fibrillation. This study examined outcomes with sternotomy versus minithoracotomy in stand-alone Cox-Maze IV procedures at our institution. METHODS: Between 2002 and 2015, 195 patients underwent stand-alone biatrial Cox-Maze IV...

INTRODUCTION    Restoring sinus rhythm in patients with atrial fibrillation (AF)/atrial flutter (AF) requires adequate oral anticoagulation (OAC) prior to direct current cardioversion (DCC). Some patients eligible for DCC are not properly anticoagulated. OBJECTIVES    Assessment of risk factors for thrombus and spontaneous echo contrast (SEC) in the left atrium (LA) as well as the safety profile of DCC under transesophageal echocardiography control (TEE) in patients with inadequate anticoagulation. PATIENTS AND METHODS    From the cohort of 316 patients admitted for DCC, 139 (age 63...

OBJECTIVE: Vascular closure devices have been used to achieve hemostasis of percutaneous access sites following endovascular procedures, with reported decreased time for arterial control as well as decreased time to ambulation. We sought to determine rates and risk factors of postoperative bleeding complications and failures using these devices from a single institution experienced in the use of vascular closure devices. METHODS: All patients undergoing arterial endovascular procedures with percutaneous access between March 2010 and October 2015 at a single institution were identified and analyzed (n=894)...

Aims: A commonly held notion is that patients with a family history of atrial fibrillation (AF) have worse atrial substrate and higher rates of arrhythmia recurrence following ablation. We sought to examine differences in atrial substrate and catheter ablation outcomes in patients with a 1st degree family member with paroxysmal or persistent AF (PeAF) compared to those without. Methods and results: A total of 256 consecutive patients undergoing their 1st ablation for AF (123 paroxysmal, 133 persistent) with >1 year follow up were included...

BACKGROUND: The reported incidence of AF after CABG surgery varies from 20 to 40%, with the arrhythmia usually occurring between second and fourth postoperative days. Postoperative AF after CABG was associated with greater in-hospital mortality and worse survival at long-term follow-up. Therefore, intensive attention has focused on the prevention of AF in high-risk patients. Many perioperative factors have been suggested to increase the incidence of postoperative AF after conventional CABG...

We assessed the relationships among adult height, coronary artery calcium (CAC) scores, incident atherosclerotic cardiovascular disease (ASCVD) events, and atrial fibrillation (Afib) in a multi-ethnic cohort. We used race/ethnicity -specific height (dichotomized by median and quartiles) as the predictor variable within the four race/ethnic groups in the Multi-Ethnic Study of Atherosclerosis (N = 6,814). After a mean of 10.2 years of follow-up (2000-2012), 556 ASCVD events (8.2%) and 539 afib events (7.9%) occurred...

BACKGROUND: Given the potential complications of atrial fibrillation (AF) recurrence after ablation, better predictors of the effectiveness of the procedure are necessary to guide patient selection. AIM: This prospective study was conducted to evaluate the clinical relevance of global left atrial longitudinal strain (GLAS) and AF recurrence after catheter ablation. METHODS: In 115 consecutive patients with AF (persistent, n=62; paroxysmal, n=53), transthoracic echocardiography was performed before catheter ablation to assess baseline left atrial mechanical function using speckle tracking echocardiography (STE)...

INTRODUCTION AND OBJECTIVES: Atrial fibrillation (AF) is an independent risk factor for mortality in several diseases. However, data published in acute decompensated heart failure (DHF) are contradictory. Our objective was to investigate the impact of AF on mortality in patients admitted to hospital for DHF compared with those admitted for other reasons. METHODS: This retrospective cohort study included all patients admitted to hospital within a 10-year period due to DHF, acute myocardial infarction (AMI), or ischemic stroke (IS), with a median follow-up of 6...

The combination of chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) is associated with substantial morbidity and mortality. We hypothesized that predictors of OSA among patients with COPD may be distinct from OSA in the general population. Therefore, we investigated associations between traditional OSA risk factors (e.g. age), and sleep questionnaires [e.g. Epworth Sleepiness Scale] in 44 patients with advanced COPD. As a second aim we proposed a pilot, simplified screening test for OSA in patients with COPD...

BACKGROUND: Patients with chronic obstructive pulmonary disease (COPD) presenting with ST-segment elevation myocardial infarction (STEMI) are less likely to beneficiate of primary percutaneous coronary intervention (pPCI), and have poorer prognosis. We aimed to evaluate the impact of COPD on the in-hospital outcomes of pPCI-treated STEMI patients. METHODS: Data were collected from 418 STEMI patients treated by pPCI. Inotropics and diuretics usage, cardiogenic shock, asystole, kidney dysfunction, and left ventricular ejection fraction were used as markers of hemodynamic complications...

BACKGROUND: A significant proportion of patients treated with warfarin for atrial fibrillation (AF) become warfarin ineligible (WI) due to major bleeding events (MBE) or systemic thromboembolism (STE). We report a large multicenter real-world experience of the use of DOACs in these WI patients. METHODS: We report the outcomes of 263 WI patients treated with DOACs. The primary objective was to evaluate clinical outcomes of STE and MBE with DOACs. Secondary objective was to assess clinical predictors of repeat MBE and STE on DOACs...

BACKGROUND: Previous reports on patients with radiofrequency catheter ablation (RFCA) of accessory pathway (AP) and atrial fibrillation (AF) include only short follow-up periods. The aim of this study was to analyse predictors of recurrence of AF in patients after successful RFCA of APs over long term follow-up periods. METHODS: Of the 1,007 patients who underwent non-pharmacological treatment of Aps ( between the years 1993-2008), data of 100 consecutive patients were retrospectively analyzed (75 men, mean age 43...

REVIEW
Martin Fiala
Persistent and long-standing persistent atrial fibrillation evolves from complex arrhythmogenic substrate and sources. Multiple studies have shown improved freedom from arrhythmia recurrences if sinus rhythm had been restored during the index ablation; however, such harder procedural endpoint requires laborious stepwise approach almost invariably pursuing non-pulmonary-vein sources. Longer-term conversion of persistent atrial fibrillation into sinus rhythm is associated with significant improvement in major indices of hemodynamic and functional status; these indices also represent major predictors of cardiovascular mortality...

Atrial fibrillation (AF) significantly increases the risk of stroke and disease burden and is an established predictor of poor outcomes after stroke. However, data regarding sex differences in long-term outcomes following stroke in patients with AF are scarce. We thus aimed to assess these differences. We recruited 951 consecutive patients with acute ischemic stroke and non-valvular atrial fibrillation (NVAF) treated at three hospitals in Tianjin, China, from January 2006 to September 2014. Information regarding stroke subtype, severity, risk factors, and outcomes (mortality, dependency, and recurrence) at 3, 12, and 36 months after stroke was recorded...

Postoperative atrial fibrillation (AF) occurs frequently after cardiac surgery and contributes significantly to mortality. Transforming growth factor-beta (TGF-β) is associated with postoperative AF after coronary artery bypass grafting and valve surgery. We performed a prospective study to evaluate the role of TGF-β as a predictor of AF after myectomy. A total of 109 consecutive obstructive hypertrophic cardiomyopathy patients without previous AF who underwent myectomy were identified. We measured plasma TGF-β levels before surgery, monitored heart rhythm until discharge, and followed patients for a mean of 36 ± 10 months...
