REVIEW

Interventional procedures for pericardial diseases include pericardiocentesis, drainage of pericardial effusion, intrapericardial therapy, and percutaneous balloon pericardiotomy or percutaneous pericardiostomy. Echocardiographic and fluoroscopic guidance have greatly increased safety and feasibility. Several devices for pericardiocentesis have been tested (PerDucer, PeriAttacher, visual puncture systems, Grasper, Scissors, and Reverse slitter), mainly to facilitate access to the pericardium in the absence of effusion for epicardial ablations or left atrial appendage ligation...

BACKGROUND: The mitral isthmus is a critical part of perimitral reentrant tachycardia, as well as an important substrate of persistent atrial fibrillation. Deployment of an endocardial mitral isthmus line (MIL) with the end point of bidirectional block may be challenging and often requires additional epicardial ablation within the coronary sinus. METHODS AND RESULTS: The study population comprised 114 patients with perimitral flutter who underwent de novo ablation of an MIL...

The aim of this EP Wire survey was to assess the indications and anticoagulation strategies post-left atrial appendage occluder (LAAO) implantation for stroke prevention in patients with non-valvular atrial fibrillation in Europe. A total of 33 centres in 13 European countries completed the survey. All centres were members of the European Heart Rhythm Association Electrophysiology Research Network. Left atrial appendage occluder procedures were performed by electrophysiologists in 52% of the centres and by interventional cardiologists in the remaining centres...

Aims: Left atrial appendage (LAA) occlusion has emerged as an interesting alternative to oral anticoagulation (OAC) for stroke prevention in patients with atrial fibrillation (AF). We report the safety, efficacy, and durability of concomitant device-enabled epicardial LAA occlusion during open-heart surgery. In addition to long-term follow-up, we evaluate the impact on stroke risk in this selected population. Methods and results: A total of 291 AtriClip devices were deployed epicardially in patients (mean CHA2DS2-VASc-Score: 3...

Atrial fibrillation (AF) is a clinically heterogeneous arrhythmia that is currently classified according to the variety of temporal rhythm based manifestations observed clinically, including 'first detected episode', 'paroxysmal', 'persistent', or 'permanent' AF. Despite being widely adopted by the most recent consensus guidelines, the utility of this classification system to stratify patients into distinct and clinically useful groups that have different outcomes including mortality, morbidity, specific cardiovascular outcomes, and quality of life (QoL), remains questionable...

BACKGROUND: Literature search reveals that postoperative atrial fibrillation (POAF) occurs in 15%-40% of coronary artery bypass graft (CABG) patients. Although several risk models exist for predicting the development of POAF, few have studied left atrial appendage (LAA) velocity. We hypothesize that an association between LAA velocity and development of POAF exists. DESIGN AND METHODS: Single institution university hospital prospective observational clinical study performed between May 2016 and November 2016 in 96 adult patients undergoing CABG surgery utilizing cardiopulmonary bypass (CPB)...

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia of high clinical importance, occurring in 2% of the general population and in 19-24% in patients with chronic kidney disease. It is a well-known risk factor for cardiovascular morbidity and mortality. Kidney transplant recipients with a history of AF were associated with significantly higher rate of ischaemic strokes, graft failure and post-transplant mortality. AF occurs in over 7% of kidney transplant recipients in the first 3 years after transplantation and is associated with reduced graft and patient survival...

It is well known that atrial fibrillation (AF) is the most frequent cardiac arrhythmia worldwide and substantially increases the risk for thromboembolic disease. One of the main problems is that it remains undiagnosed (about 20% of all cases of AF). On the other hand, hypertension amplifies the risk for both AF occurrences through hemodynamic and non-hemodynamic mechanisms and cerebrovascular ischemia. Under this prism, prompt diagnosis of undetected AF in hypertensive patients is of pivotal importance. Biomarkers could be used in AF diagnosis as well as in predicting the transition of paroxysmal AF to sustained AF...

BACKGROUND: Percutaneous left atrial appendage closure (LAAC) is a viable option for AF patients who are unable to tolerate long term oral anticoagulation (OAC). OBJECTIVE: We sought to assess the safety of two commonly used percutaneous devices for LAA closure in the United States by analysis of surveillance data from the FDA Manufacturer and User Facility Device Experience (MAUDE) database. METHODS: The MAUDE database was queried between May 1, 2006 and May 1, 2016 for LARIAT® (SentreHEART Inc...

AIMS: Postdeployment mutual orientation between the disk and the lobe in patients undergoing left atrial appendage closure with Amplatzer cardiac plug/Amulet device might impact on the risk of residual leak during follow-up. Thus, we evaluated in an exploratory, pilot study whether the degree of intradevice misalignment, measured by cardiac computed tomography (CT), discriminates the occurrence of peridevice leak in those patients. METHODS: All patients (N = 15) undergoing percutaneous left atrial appendage closure with those specific devices between April 2013 and January 2015 were prospectively included...

Left atrial appendage (LAA) aneurysm is an extremely rare anomaly. So far, less than one hundred cases only have been reported worldwide. Revelation modes are dominated by complications such as arrhythmias and thromboembolic events. We herein report a pediatric case of huge congenital LAA aneurysm with an original revelation mode that has never been described before in medical literature.

BACKGROUND: The left atrial appendage is involved in secretion of N-terminal-pro B-type Natriuretic Peptide (NT-proBNP). Percutaneous left atrial appendage occlusion (LAAO) for prevention of stroke may cause the variations in NT-proBNP release. AIM: This study aimed to assess the diagnostic value of NT-proBNP after LAAO. METHODS: The study group consisted of 53 patients in whom LAAO were performed. The patients with heart failure (HF) and reduced ejection fraction (EF) were allocated to Group I (n=16) whereas patients with no HF symptoms and EF>40% to Group II (n=37)...

BACKGROUND: Inhibition of the renin-angiotensin axis can reduce the likelihood of atrial fibrillation (AF). However, the effects of angiotensin-converting-enzyme inhibitors (ACEIs) or angiotensin II receptor blockers (ARBs) on thrombogenicity in AF remain incompletely elucidated. Thisretrospective case-control study was conducted to evaluate whether the use of ACEI or ARB could reduce the incidence of left atrial appendage thrombus (LAAT) and spontaneous echocardiographic contrast (SEC) in patients with AF...

METHODS AND RESULTS: Between June 2009 and November 2016, 457 consecutive patients (63% males, 75±12 yrs, CHA2DS2-VASc 4±0.6, HASBLED 3.5±0.7) undergoing LAAO were included. Technical success was 97.1%. There were 19 periprocedural major adverse events (4.1%) including three deaths (0.6%), nine tamponades (1...

BACKGROUND: Radiofrequency ablation (RFA) is an important and promising therapy for atrial fibrillation (AF) patients. Optimization of patient selection and the availability of an accurate anatomical guide could improve RFA success rate. In this study we propose a unified, fully automated approach to build a 3D patient-specific left atrium (LA) model including pulmonary veins (PVs) in order to provide an accurate anatomical guide during RFA and without PVs in order to characterize LA volumetry and support patient selection for AF ablation...
