PURPOSE: The electrical coupling index (ECI) (Abbott, USA) is a marker of tissue contact and ablation depth developed particularly for atrial fibrillation treatment. We sought to evaluate if these measures can be also a marker of lesion efficacy during cavotricuspid isthmus (CTI) ablation for typical right atrial flutter. METHODS: We assessed the ECI values in patients undergoing typical right atrial flutter point-by-point ablation guided by the Ensite Velocity Contact™ (St...

Left ventricular assist device (LVAD) therapy has emerged as an increasingly vital facet of the treatment algorithm for advanced heart failure. Growing experience with LVAD support has led to substantial improvements in outcomes, with 1-year survival rates approaching that of cardiac transplantation. These therapeutic refinements have engendered growing interests in the potential for expanding the clinical indications for LVAD therapy to patients with less advanced heart failure. The primary obstacles to this evolution of care center largely on the prevention and/or management of the adverse events associated with LVAD therapy along with patient preference...

BACKGROUND: The unrest in Syria has resulted in an escalating refugee crisis. The postwar lack of health care infrastructure in Iraq has also resulted in Iraqis seeking health care in neighboring countries. Pediatric cancer is largely curable, although its treatment is expensive and complex. Strategies to implement pediatric cancer care with curative intent in these vulnerable populations are lacking. METHODS: To assess the feasibility of a collaborative approach for the provision of care to displaced children with cancer, this study reviewed the experience of the authors over the past 6 years in Lebanon, the country with the highest number of refugees per capita in the world...

To report on a less-invasive technique for replacing a broken lead in a spinal cord stimulation (SCS) device that makes use of St. Jude Medical's "Epiducer" device. A 53-year-old woman suffered a loss of stimulation on her internal pulse generator (IPG), which was found to have a broken lead. The broken lead was withdrawn using the Epiducer device with minimal invasiveness and without pain. A new lead was put in place, and successful stimulation using the IPG resumed. Follow-up 3 weeks later showed a well-functioning SCS system...

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...

A 5-month-old infant, referred to our institution for percutaneous arterial duct (AD) embolization, showed multiple huge pulmonary arteriovenous malformations (PAVMs) associated with a small AD and several tiny systemic-to-pulmonary collaterals. This anatomic arrangement was a possible cause of lack of cyanosis and disproportionately higher hemodynamic relevance of the ductal shunt. The PAVMs became pathophysiologically evident immediately after the closure of AD and systemic to pulmonary artery collaterals and presented clinically with a life-threatening cyanosis...

Sinus of Valsalva (SV) rupture is a rare, cardiac complication after surgical repair of complex congenital heart disease. This paper reports a 4-year-old male child with double outlet right ventricle (RV) and pulmonary stenosis with superior-inferior arrangement of the ventricles, who was submitted to surgical repair using the "reparation a l'etage ventriculaire" procedure. A few months after an uneventful surgical repair, his clinical condition abruptly worsened because of the rupture of the right SV into the RV outflow tract resulting in large left-to-right shunt and RV functional impairment...

BACKGROUND: Patients who are candidates to receive an Angioseal® (St. Jude Medical) device for arteriotomy closure are allowed to ambulate 20 min after the deployment of the device. More frequently, however, patients are kept on bed rest for several hours following Angioseal® deployment. The purpose of this study was to prospectively assess patients when ambulating 20 min after Angioseal® deployment instead of prolonged best rest of 2-3 h. METHODS: Patients undergoing angiography from the common femoral artery approach were included in the study if they received a 6 Fr Angioseal® closure device...

Trancatheter heart valve (THV) thrombosis is effectively treated with anticoagulation but alternative therapies are required when a faster gradient reduction is needed. Open heart surgery has been rarely performed due to the high perioperative mortality and only five cases have been described so far. Here we describe a case of emergent surgical explantation for THV thrombosis after a valve-in-valve. A 67years old man underwent transcatheter aortic valve implantation for a failed surgical bioprosthesis Epic 21mm (St...

BACKGROUND: Atrioventricular nodal reentrant tachycardia (AVNRT) is a common tachyarrhythmia substrate in children, which is successfully treated by catheter ablation using radiofrequency or cryothermal energy. In recent years, cryoablation (Cryo) using electroanatomical system guidance is more commonly preferred for use in children in order to decrease the risk of an atrioventricular block. However, there are concerns regarding the long-term efficacy of Cryo in treating AVNRT. We aimed to evaluate the feasibility, safety, and long-term efficacy of Cryo for AVNRT in children...
