We report the entrapment of Pulmonary Vein Ablation Catheter (Medtronic) and its guidewire within the right pulmonary veins in two patients. The catheters could be retrieved without complications but they were disabled in both cases. This non-described incident should be recognized by PVAC users since it may be a source of potential severe complications during pulmonary veins isolation procedures.

A 25 year old gentleman with history of previous radiofrequency (RF) ablation done for WPW syndrome involving left lateral accessory pathway has presented with recurrent episodes of paroxysmal palpitation. During one of the episodes a regular narrow QRS tachycardia which is responsive to adenosine is documented. The current surface electrocardiogram shows preexcitation. Patient has undergone a redo-electrophysiological study after informed consent. Catheters are positioned at coronary sinus (CS), right ventricular apex (RVA), His bundle region (His) and right atrial appendage (RA)...

BACKGROUND: The WEARIT-II Registry demonstrated efficacy and safety of the WCD for at-risk cardiac patients. However, one-year outcomes in this population have not been reported. METHODS: The WEARIT-II Registry enrolled 2000 US patients prescribed the WCD. One-year mortality data from start of WCD use were prospectively collected for 1846 patients (93%). Outcome data were analyzed by disease etiology, and ICD implantation following WCD use. RESULTS: During 12 months of follow-up, 73 patients died (4%)...

Guy Vaksmann, Didier Klug
Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a potentially lethal hereditary disease characterized by complex ventricular arrhythmias provoked by exercise or emotional stress and by a high mortality rate in young individuals. Nadolol alone or in combination with flecainide is the most effective therapy. However, compliance to treatment is often low due to side effects. We report 2 patients with CPVT in whom side effects of treatment prompted discontinuation of Flecainide or Nadolol and in whom Ivabradine was successfully added to therapy...

A 75-year-old male patient was referred for longstanding atrial fibrillation ablation. We performed this procedure combining an epicardial and endocardial approach. Under general anesthesia and via a left-sided thoracoscopic approach, we isolated the pulmonary veins (PVs) and the, inferior line were created using a radiofrequency tools. To isolate the endocardial PVs a transseptal puncture was performed via the groin, and a cryo ablation CoolLoop catheter was advanced into the left atrium. Ice crystals started to appear on the epicardial surface of the left inferior PV antrum after 121 seconds later, those crystals had formed an ice plaque...

BACKGROUND: Alternative right ventricular (RV) sites (RVAPS) have been proposed to prevent or reduce RV pacing-induced left-ventricular (LV) dysfunction. Non-fluoroscopic 3D-electroanatomic mapping systems (EAM) have been developed to guide cardiac catheter navigation and reduce fluoroscopy during electrophysiological procedures or pacemaker implantations. AIM: The aim of the study was to compare the results of EAM-guided permanent pacemaker implantation aiming at RVAPS with conventional fluoroscopic-guided implantation in RV apex (RVA) in children and adolescents...

INTRODUCTION: We previously reported on a subgroup of postural orthostatic tachycardia syndrome (POTS) patients who may also have features of neurocardiogenic syncope (NCS) as well. In this subgroup of patients we found syncope and pre syncope were predominant clinical features. To understand the mechanism of syncope in this sub-group we identified 39 patients who underwent loop recorder insertion. METHODS: We reviewed charts of 450 patients who had POTS and Syncope seen at University of Toledo medical center from 2003 to 2017...

BACKGROUND: Left ventricular false tendons (FT) traverse the ventricular cavity and are thought to have some association with idiopathic left ventricular tachycardia (ILVT). However, reported prevalence of FT varies widely, making correlation difficult. Superior echocardiographic windows of pediatric patients may permit better analysis of FT in ILVT. Our study describes the relationship between FT and ILVT in young patients. METHODS: Retrospective case-control study of 30 ILVT patients with 98 controls compared for FT...

INTRODUCTION: Infection remains a dreaded complication after cardiac implanted electronic device (CIED) placement. The prognostic value of the pre-operative white blood cell (WBC) count, in the absence of other signs of infection, at time of CIED placement as a predictor of post-operative infection has not been previously examined. METHODS: The study population included 1,247 consecutive device implantations over a four-year period that met inclusion criteria. The association between pre-operative WBC count and resultant infection post-operatively was examined...

BACKGROUND: Patient-reported outcomes of implantable cardioverter defibrillator (ICD), such as those with shock anxiety, have emerged as important endpoints that are related to quality of life (QOL), but they have not been well studied in a sample of the Japanese population. Therefore, we prospectively examined changes in shock anxiety in a large sample of Japanese patients with an ICD. METHODS: We recruited 214 consecutive patients with an ICD who visited the outpatient clinic...

BACKGROUND: Post-operative atrial fibrillation (POAF) occurs in 20-40% patients who received isolated coronary artery cardiac bypass surgery (CABG). Several POAF risk prediction models have been developed, but none of them is widely adopted in practice. Our objective was to derive and validate a simple scoring system to estimate POAF risk after isolated CABG, using easily available clinical information. METHODS: Medical records of 1000 consecutive patients undergoing isolated CABG were reviewed...

BACKGROUND: Clinical guidelines recommend cardioverter defibrillator implantation for patients with heart failure and reduced ejection fraction. Despite this, women and minorities have been less likely to receive implantable cardioverter-defibrillator (ICD) therapy than white men. We examined race and sex differences in ICD implantation in a recent cohort. METHODS: Using cross sectional, retrospective analyses, we mined our health system's outpatient electronic medical records to assess age, race, sex, medications, and comorbidities for patients aged ≥18 years with ejection fraction ≤ 35% during 2014...

Diverging channels of activation may be observed in some VT using ultra-high density mapping. We present here cases of such diverging activation patterns as observed from 60 consecutive VT activation maps using the Rhythmia system ™. Diverging directions of activation in the same area with "crossroads" or "flyover" pattern can be traced, implying recording of independent multilayer channels. Adaptation of current automated recording by the 3D mapping system is mandatory for better investigating this phenomenon This article is protected by copyright...
