BACKGROUND: In patients with ventricular tachycardia/fibrillation (VT/VF) electrical storm (ES) undergoing catheter ablation (CA), hypotension due to refractory VT/VF, use of anesthesia and cardiac stunning due to repeated ICD shocks might precipitate acute hemodynamic decompensation (AHD). OBJECTIVE: We evaluated the outcomes of emergent cardiopulmonary support with extracorporeal membrane oxygenation (ECMO) to rescue AHD in patients undergoing CA of ES. METHODS: Between 2010 and 2016, 21 patients with ES (VT in 11 and PVC-triggered VF in 10) were referred for CA and had periprocedural AHD requiring emergent ECMO support...

BACKGROUND: Catheter ablation is now a mainstay of therapy for ventricular arrhythmias (VA). However, there are scenarios where either physiologic or anatomical factors make ablation less likely to be successful. OBJECTIVES: To demonstrate that cardiac sympathetic denervation (CSD) may be an alternate therapy for patients with difficult to ablate VA. METHODS: We identified all patients referred for CSD at a single center for indications other than LQTS and CPVT who had failed catheter ablation...

Background -Atrial fibrillation (AF), the most common sustained arrhythmia in hypertrophic cardiomyopathy (HCM), is capable of producing symptoms that impact quality of life and is associated with risk for embolic stroke. However, the influence of AF on clinical course and outcome in HCM remains incompletely resolved. Methods -Records were accessed of 1558 consecutive patients followed at the Tufts Medical Center Hypertrophic Cardiomyopathy Institute for 4.8 ± 3.4 years, from 2004 to 2014. Results -Of the 1558 HCM patients, 304 (20%) had episodes of AF, of which 226 (74%) were confined to symptomatic paroxysmal AF (PAF; average 5 ± 5; range 1 to > 20), while 78 (26%) developed permanent AF, preceded by 7 ± 6 PAF episodes...

INTRODUCTION: Induction of labour for prolonged pregnancies (PP) when the cervix is unfavourable is a challenging situation. Cervical ripening by pharmacological or mechanical techniques before oxytocin administration is used to increase the likelihood of vaginal delivery. Both techniques are equally effective in achieving vaginal delivery but excessive uterine activity, which induces fetal heart rate (FHR) anomalies, is more frequent after the pharmacological intervention. We hypothesised that mechanical cervical ripening could reduce the caesarean rate for non-reassuring FHR especially in PP where fetuses are already susceptible to this...

Transcutaneous or transvenous pacing of the right ventricle is performed as a routine practice for patients received with symptomatic bradycardia or complete heart block with relative ease in cath lab. However, more and more patients are received with multiple comorbidities, critical condition, and difficult vascular access. In this article, we describe a patient with difficult venous access with tricuspid regurgitation and displaced the right ventricular pacemaker temporary lead undergoing coronary angiography who was managed with emergent nonconventional left ventricular pacing...

The pathophysiology and the management of patients with acute right heart failure are very complex. The bed-side focused echocardiography is the basis of differential diagnosis and acute diagnosis. Individual therapy monitoring is complex due to the strong preload dependence of the right ventricle and the limitation of non-invasive estimation of pulmonary-vascular hemodynamics, so that the indication for a pulmonary artery catheter should be liberal in acute right heart failure. The treatment goals of acute right heart failure are the treatment of the underlying disease or triggering factors in combination with individualized optimization of hemodynamic tailored to current right-ventricular function...

PURPOSE OF REVIEW: Ventricular tachycardia occurrence in implantable cardioverter defibrillator (ICD) patients may result in shock delivery and is associated with increased morbidity and mortality. In addition, shocks may have deleterious mechanical and psychological effects. Prevention of ventricular tachycardia (VT) recurrence with the use of antiarrhythmic drugs or catheter ablation may be warranted. Antiarrhythmic drugs are limited by incomplete efficacy and an unfavorable adverse effect profile...

BACKGROUND: Fluoroless transseptal (TS) puncture may represent the final step towards elimination of fluoroscopy in pediatric supraventricular tachycardia ablation in normal hearts. We aimed to demonstrate the safety and feasibility of fluoroless TS puncture in pediatric patients and compare procedural timing with the fluoroscopic approach. METHODS: We performed a retrospective cohort analysis of all TS procedures performed without fluoroscopy at our institution; fluoroless TS procedures were performed under intracardiac echocardiography (ICE) guidance after creation of 3D electroanatomic map and identification of fossa ovalis on 3D map...

Robotic cardiac catheterization using ultrasound (US) imaging catheters provides real time imaging from within the heart while reducing the difficulty in manually steering a four degree-of-freedom (4-DOF) catheter. Accurate robotic catheter navigation in the heart is challenging due to a variety of disturbances including cyclical physiological motions, such as respiration. In this work we compensate for respiratory motion by using an Extended Kalman Filter (EKF) to predict target motion and by applying the predictions to steer the US imaging catheter...

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) has become lately the procedure of choice in the treatment of most pathologies of descending thoracic aorta. Aortic arch aneurysms also came to be treated by TEVAR with various hybrid techniques or custom made scalloped/fenestrated stent-grafts. Zone 0; ascending TEVAR is more challenging than TEVAR of the descending thoracic aorta or aortic arch because of the more complex pathology, hemodynamics, and anatomy. Ascending TEVAR can be a lifesaving treatment in selected high surgical risk patients...

OBJECTIVE: We sought to evaluate the risk and image quality from cardiovascular CT in patients across all stages of single-ventricle palliation, and to define accuracy by comparing findings with intervention and surgery. METHODS: Consecutive CT scans performed in patients with single-ventricle heart disease were retrospectively reviewed at a single institution. Diagnosis, sedation needs, estimated radiation dose, and adverse events were recorded. Anatomical findings, image quality (1-4, 1=optimal), and discrepancy compared with interventional findings were determined...
