Papillary ibroelastomas are small benign intracardiac tumors known for their embolic potential. Since the introduction of echocardiography with improved resolution and transesophageal imaging techniques, they are being increasingly detected in clinical practice. In recent series, papillary fibroelastoma is considered the most frequent benign tumor of the heart. Our objective was to analyze characteristics and midterm surgical outcome of histologically-confirmed cases of papillary fibroelastoma. We conducted a retrospective study on patients with cardiac tumors submitted to surgical excision between June 1992 and February 2017...

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...

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: Cardiac pacing can be challenging after a Fontan operation, and limited data exist regarding pacing in adult Fontan patients. The objectives of our study were to determine risk factors for pacing and occurrence of device-related complications (DRCs) and pacemaker reinterventions. METHODS: We performed a retrospective review of Fontan patients from 1994 through 2014. We defined DRCs as lead failure, lead recall, cardiac perforation, lead thrombus/vegetation, or device-related infection, and cardiovascular adverse events (CAEs) as venous thrombosis, stroke, death, or heart transplant...

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...

BACKGROUND: The effects of cardiac resynchronization therapy (CRT) on secondary mitral regurgitation (MR), and mitral valve (MV) and left ventricular (LV) geometry, in patients with prior inferior myocardial infarction is not clearly defined. We assessed these outcomes utilizing 2-dimensional echocardiography, and analyzed echocardiographic geometric variables that may correlate with follow-up MR severity. METHODS: Between 2009 and 2012, 229 CRT were implanted. Twenty-two had prior inferior myocardial infarction, ≥ mild MR at baseline, and serial echocardiography...

Accurate assessment of the left atrial appendage (LAA) is important for pre-procedure planning when utilizing device closure for stroke reduction. Sizing is traditionally done with transesophageal echocardiography (TEE) but this is not always precise. Three-dimensional (3D) printing of the LAA may be more accurate. 24 patients underwent Watchman device (WD) implantation (71 ± 11 years, 42% female). All had complete 2-dimensional TEE. Fourteen also had cardiac computed tomography (CCT) with 3D printing to produce a latex model of the LAA for pre-procedure planning...

BACKGROUND: Recent data suggest that circulating biomarkers may predict outcome in patients undergoing transcatheter aortic valve replacement (TAVR). We examined the association between inflammatory, myocardial, and renal biomarkers and their role in ventricular recovery and outcome after TAVR. METHODS AND RESULTS: A total of 112 subjects undergoing TAVR were included in the prospective registry. Plasma levels of B-type natriuretic peptide, hs-TnI (high-sensitivity troponin I), CRP (C-reactive protein), GDF-15 (growth differentiation factor 15), GAL-3 (galectin-3), and Cys-C (cystatin-C) were assessed before TAVR and in 100 sex-matched healthy controls...
