Atrial fibrillation is commonly coexistent with heart failure, and the management of the heart failure patient would be incomplete without an appreciation for atrial fibrillation management. There are many complications associated with oral anticoagulation in the prevention of stroke related to atrial fibrillation. In recent years, the advent of several percutaneous left atrial appendage (LAA) occlusion/closure strategies has sought to provide an alternative treatment modality. Here, we systematically review the published literature to investigate the efficacy and safety of percutaneous LAA occlusion/closure devices...

The characteristics and predictors of long-term recurrent ischemic cardiovascular events (RICEs) after myocardial infarction with ST-segment elevation (STEMI) have not yet been clarified. We aimed to characterize the 10-year incidence, types, and predictors of RICE. We obtained 10-year follow-up of STEMI survivors at 17 Quebec hospitals in Canada (the AMI-QUEBEC Study) in 2003. There were 858 patients; mean age was 60 years and 73% were male. The majority of patients receive reperfusion therapy; 53.3% and 39...

Background: Brugada syndrome (BrS) is an inherited channelopathy, which is associated with sudden cardiac death due to rapid polymorphic VT or VF. There is no definite consensus regarding the management of asymptomatic patients. Some experts advocate close follow-up; others propose the programmed stimulation for risk stratification. We aimed to evaluate the benefit of complete atrial and ventricular stimulation in patients with BrS and palpitation. Case Presentation: A 30-year-old man was admitted to our hospital because of a family history of sudden cardiac death (SCD) at age less than 45 years...

Human induced pluripotent stem cells (hiPSCs) act as a promising therapeutic alternative for cardiovascular diseases. They yield a large number of functional cardiomyocytes (CMs) from autologous cell sources without ethical or immunological problems. However, significant limitations still remain in terms of line-to-line variability in CM yield and reproducibility. AIM: To efficiently enhance NP0040 hiPSCs differentiation into CMs. MAIN METHODS: Following a standard cardiac differentiation protocol using small molecules targeting the canonical Wnt signaling, growth factors (BMP4 and FGF2) and ascorbic acid were added further in order to increase the cardiac differentiation efficiency...

With improved surgical techniques and medical management for patients with congenital heart diseases, more patients are living longer and well into adulthood. This improved survival comes with a price of increased morbidity, mainly secondary to increased risk of tachyarrhythmias. One of the major arrhythmias commonly encountered in this subset of cardiac patients is AF. Similar to the general population, the risk of AF increases with advancing age, and is mainly secondary to the abnormal anatomy, abnormal pressure and volume parameters in the hearts of these patients and to the increased scarring and inflammation seen in the left atrium following multiple surgical procedures...

The pheochromocytome is a localized tumor at the level of the medullosurrenale in 85% of the cases. The clinical presentation is very variable. Severe Heart failure presentation can be the mode of revelation in 2% of the cases. We present the case of a patient admitted for refractory cardiogenic shock correlated to pheochromocytome tumor. The difficulty of this rare clinical presentation was to confirm rapidly and in emergency this diagnosis in the same time when the patient presents a persistante and severe cardiogenic chock after finding a sub-occluded and thrombotic LAD coronary artery and which was treated by thrombectomy and coronary revascularization...

One of the important parts of the cardiac system is aorta which is the fundamental channel and supply of oxygenated blood in the body. Diseases of the aorta represent critical cardiovascular bleakness and mortality around the world. This study aims at investigation of hemodynamic parameters in a two-dimensional axisymmetric model of three-layer grafted aorta using fluid-structure interaction (FSI). It assumes that a damaged part of aorta, which may happen as a result of some diseases like aneurysm, dissection and post-stenotic dilatation, is replaced with a biomaterial graft...

INTRODUCTION: Manual, point-by-point electroanatomical mapping requires the operator to directly evaluate each point during map construction. Consequently, point collection can be a slow process. An automated 3D mapping system was developed with the goal of improving key mapping metrics, including map completion time and point density. METHODS: Automated 3D mapping software that includes morphology and cycle length discrimination functions for surface and intracardiac electrograms was developed...

A 32-year-old man referred to the cardiology clinic for palpitations was found to have paroxysmal supraventricular tachycardia (SVT) on 24-hour Holter monitoring. His general and cardiac examinations were unremarkable. A transthoracic echocardiographic study to exclude structural heart disease was performed and showed an abnormal structure in relation to the right ventricular (RV) free wall; however, poor echocardiographic windows precluded proper characterisation. Cardiac MR (CMR) was therefore performed...

BACKGROUND AND PURPOSE: Spontaneous visual recovery is rare after cortical blindness. While visual rehabilitation may improve performance, no visual therapy has been widely adopted, as clinical outcomes are variable and rarely translate into improvements in activities of daily living (ADLs). We explored the potential value of a novel rehabilitation approach "cognitive therapeutic exercises" for cortical blindness. CASE DESCRIPTION: The subject of this case study was 48-year-old woman with cortical blindness and tetraplegia after cardiac arrest...
