BACKGROUND: Performance of tricuspid annuloplasty (TA) in patients undergoing mitral valve surgery is recommended based on the degree of tricuspid regurgitation and tricuspid annulus size, but is often underused. AIM: To evaluate the impact of combined TA on in-hospital outcome in patients undergoing mitral valve replacement (MVR). METHODS: We selected all consecutive patients who underwent MVR for native valve disease. Clinical, echocardiographic and in-hospital complications were obtained from chart review...

INTRODUCTION: Percutaneous left atrial appendage (LAA) occlusion is an emerging treatment option for patients with non-valvular atrial fibrillation who cannot tolerate oral anticoagulation. The Watchman device (Boston Scientific Corporation, Natick, MA, USA) is deployed at the ostium of the LAA, and an appropriately sized device is critical for successful occlusion. However, standardized imaging protocols for device sizing have not been established. OBJECTIVES: We investigated the clinical utility of a standardized imaging protocol, with pre-procedural multi-detector cardiac computed tomography (MDCT), and intra-procedural transesophageal echocardiography (TEE), for Watchman device sizing...

INTRODUCTION: The aim of this study was to compare the risk of ischemic stroke in patients who have atrial fibrillation and patients who have atrial flutter. METHODS: Using inpatient and outpatient Medicare claims data from 2008 to 2014 for a 5% sample of all beneficiaries 66 years of age or older, we identified patients diagnosed with atrial fibrillation and those diagnosed with atrial flutter. The primary outcome was ischemic stroke. In the primary analysis, patients with atrial flutter were censored upon converting to fibrillation; in a secondary analysis, they were not...

BACKGROUND: Balloon aortic valvuloplasty (BAV) is often utilized as a bridge prior to surgical or transcatheter aortic valve replacement. Chronic kidney disease (CKD) is commonly present in patients with aortic stenosis, however, its association with outcomes following BAV has not been well studied. Accordingly, we sought to assess the impact of CKD on mortality in adults undergoing BAV. METHODS: The Nationwide Inpatient Sample was screened for hospitalizations involving adults undergoing BAV from 2006 to 2012...

Edoxaban-a non-vitamin K antagonist oral anticoagulant (NOAC)- 60-mg and 30-mg once-daily dose regimens are noninferior versus well-managed warfarin for the prevention of stroke or systemic embolic events (SEE) with less major bleeding in patients with nonvalvular atrial fibrillation (NVAF). There are no published data from phase 3 clinical trials specifically evaluating the use of NOACs in elderly NVAF patients, especially those considered ineligible for available oral anticoagulants. The Edoxaban Low-Dose for EldeR CARE AF patients (ELDERCARE-AF) study is a phase 3, randomized, double-blind, placebo-controlled, parallel-group, multicenter study that will compare the safety and efficacy of once-daily edoxaban 15 mg versus placebo in Japanese patients with NVAF ≥80 years of age who are considered ineligible for standard oral anticoagulant therapy...

BACKGROUND: Appropriate thromboprophylaxis for patients with atrial fibrillation or atrial flutter (AF) remains a national challenge. The recent availability of direct oral anticoagulants (DOACs) with comparable efficacy and improved safety compared with warfarin alters the balance between risk factors for stroke and benefit of anticoagulation. Our objective was to examine the impact of DOACs as an alternative to warfarin on the net benefit of oral anticoagulant therapy (OAT) in a real-world population of AF patients...

Atrial fibrillation (AF) is the most common cardiac arrhythmia in the world. We aimed to provide comprehensive data on international patterns of AF stroke prevention treatment. METHODS: Demographics, comorbidities, and stroke risk of the patients in the GARFIELD-AF (n=51,270), ORBIT-AF I (n=10,132), and ORBIT-AF II (n=11,602) registries were compared (overall N=73,004 from 35 countries). Stroke prevention therapies were assessed among patients with new-onset AF (≤6 weeks). RESULTS: Patients from GARFIELD-AF were less likely to be white (63% vs 89% for ORBIT-AF I and 86% for ORBIT-AF II) or have coronary artery disease (19% vs 36% and 27%), but had similar stroke risk (85% CHA2DS2-VASc ≥2 vs 91% and 85%) and lower bleeding risk (11% with HAS-BLED ≥3 vs 24% and 15%)...

BACKGROUND: Handheld ECG event recorders are useful for rhythm monitoring but only record a single lead, which may limit interpretation. We sought to investigate if a multi-lead ECG may be reconstituted using this device, and aimed to evaluate diagnostic accuracy. METHODS: A commercially-available handheld bipolar ECG event recorder was used to reconstruct a 9-lead ECG (leads I, II and III, V1-6). Tracings were analyzed independently by a cardiologist and a fellow...

We describe a patient with perimitral atrial flutter (PMF) following the atrial fibrillation ablation and the linear ablation at the mitral isthmus (MI). From both the activation and the voltage maps using ultra-high resolution mapping, we detected the epicardial connection through the coronary sinus (CS) within the entire reentrant circuit. Point ablation within the CS, not additional linear MI ablation from the endocardium terminates PMF, with a bidirectional block across the low voltage area at the MI.

BACKGROUND: During atrial fibrillation, heterogeneities and anisotropies result in a chaotic propagation of the depolarization wavefront. The electrophysiological parameter called conduction velocity (CV) influences the propagation pattern over the atrium. We present a method that determines the regional CV for deformed catheter shapes, which result due to the catheter movement and changing wall contact. METHODS: The algorithm selects stable catheter positions, finds the local activation times (LAT), considers the wall contact and calculates all CV estimates within the area covered by the catheter...

Inhye E Ahn, Matthew S Davids
A 70-year-old man with relapsed/refractory chronic lymphocytic leukemia has multiple comorbidities including atrial fibrillation (on warfarin for anticoagulation), irritable bowel syndrome, and chronic renal insufficiency. Two years ago, he received bendamustine and rituximab as first-line therapy for chronic lymphocytic leukemia and achieved partial response, but now has relapsed. Fluorescence in situ hybridization cytogenetics reveals deletion 17p. Which novel agent would you recommend for this patient?

BACKGROUND: Few studies have examined outcomes of catheter ablation for atrial fibrillation (AF) in patients with heart failure with preserved ejection fraction (HFpEF). OBJECTIVE: Compare outcomes of AF ablation in patients with HFpEF versus HF with reduced ejection fraction (HFrEF). METHODS: We performed a retrospective study of 230 patients with HF who underwent AF ablation, including 97 (42.2%) with HFrEF and 133 (57.8%) with HFpEF. Outcomes included adverse events, symptoms (Mayo AF Symptom Inventory [MAFSI]), New York Heart Association (NYHA) functional class, and freedom from recurrent atrial arrhythmia at 12-months...

External transthoracic direct current (DC) cardioversion is a commonly used method of terminating cardiac arrhythmias. Previous research has shown that DC cardioversion resulted in myocardial injury as evidenced by increased levels of cardiac troponin, even though only minimally. Many of these studies were based on the outdated monophasic defibrillators and older, less sensitive troponin assays. This study aimed to assess the effect of external transthoracic DC cardioversion on myocardial injury as measured by the change in the new high-sensitivity cardiac troponin T (hs-cTnT) using the more modern biphasic defibrillators...

Benefits of cardiorespiratory fitness on cardiovascular health are well recognized, but the impact on incidence of atrial fibrillation (AF) and stroke, and, particularly, risk of stroke and mortality in patients with AF is less clear. From 1993 to 2010, patients referred for a treadmill exercise test (TMET) at the Mayo Clinic Rochester, MN, were retrospectively identified (N = 76,857). From this, 14,094 local residents were selected. Exclusions were age <18 years; history of heart failure, structural or valvular heart disease, AF or flutter, or stroke...

BACKGROUND: Atrial fibrillatory cycle length has been considered one of the indices of atrial electrical remodelling during atrial fibrillation (AF), which can be assessed from surface ECG by computer-assisted calculation of atrial fibrillatory rate (AFR). Horses have been suggested as a bona fide model for AF studies since horses too, develop lone AF, however data on AF characteristics in horses are extremely sparse and non-invasive characterization of AF complexity using surface ECG processing has not been reported...

Peritoneopericardial diaphragmatic hernia is a rare entity involving herniation of abdominal viscera through the diaphragm into the pericardial sac. It is most often seen after blunt abdominal trauma, but can occur following any trans-diaphragmatic intervention. We report on a 56-year-old female with peritoneopericardial diaphragmatic hernia secondary to a convergent procedure for the treatment of atrial fibrillation, who underwent a laparoscopic repair. An anterior abdominal wall laparoscopic approach was employed...
