Moustafa O Elsheshtawy, Ahmed N Mahmoud, Mahmoud Abdelghany, Ida H Suen, Adnan Sadiq, Jacob Shani
BACKGROUND: Hypertrophic cardiomyopathy (HCM) with or without left ventricular apical aneurysm (LVA) had been studied in the past. Midventricular obstruction associated with HCM and LVA is a unique entity that has not been distinguished previously as a separate phenotypic disease in HCM patients. METHODS: A systematic review of Pubmed and Google Scholar was conducted from inception until September 2017 for all observational studies conducted on HCM with midventricular obstruction and LVA...

BACKGROUND: The early and correct diagnosis of cardiac implantable electronic device (CIED) infections is critical given that early aggressive treatment with complete removal of the system along with antimicrobial therapy dramatically improves outcomes. Pocket infection manifested by local signs of inflammation is the most common form of CIED infections. Conditions mimicking pocket infection have been described in the literature. These include various types of malignancy and rarely allergic reactions/contact dermatitis to pacemaker compounds...

Krishna Kumar Mohanan Nair, Narayanan Namboodiri, Hiren Kevadiya, Ajitkumar Valaparambil
A 30 year old gentleman with no structural heart disease has been evaluated for paroxysmal palpitation with documented regular wide QRS tachycardia that has not responded to IV adenosine. Surface electrocardiogram has not shown any pre-excitation. He has been taken for an EP study after informed consent. Diagnostic catheters were placed at coronary sinus (CS), His bundle region and right ventricle (RV). During catheter manipulation a regular wide QRS tachycardia with right bundle branch block morphology (RBBB) with a tachycardia cycle length (TCL) of 400 ms and normal QRS axis similar to the clinical tachycardia got induced (Fig:1)...

Reina Bianca Tan, Ivan Gando, Lei Bu, Frank Cecchin, William Coetzee
BACKGROUND: Atrial standstill is an arrhythmogenic condition characterized by the absence of spontaneous electrical and mechanical atrial activity or in response to stimulation. There are few reported familial cases which have been associated with SCN5A mutations co-segregating with GJA5 or RYR2 however isolated SCN5A mutations are rare. OBJECTIVE: The purpose of this study was to determine the clinical and biophysical consequence of a novel SCN5A mutation identified in a family with progressive atrial standstill and sudden death...

BACKGROUND: Patients with chronic Chagas cardiopathy (CCC), which may be associated with cardiac arrhythmias, frequently use amiodarone, an anti-arrhythmic drug that, experimentally, appears to modulate the cardiac autonomic function. OBJECTIVE: The present cross-sectional observational study aimed to evaluate autonomic cardiac modulation in patients with CCC undergoing chronic amiodarone therapy. METHODS: Three groups were investigated: Group 1 included patients with CCC not treated with amiodarone (n = 27); Group 2 included patients with CCC with prolonged use (at least 6 months) of amiodarone (n = 16); and Group 3 including non-chagasic control patients (n = 23)...

David Laslett, Ralph J Verdino, James N Kirkpatrick
BACKGROUND: Given the prohibitive cost of pacemakers and defibrillators for medically underserved patients in low-income countries, these devices are sometimes recovered from funeral homes for charitable re-implantation. Many devices are implanted near the end of the patients' lives, meaning that recovered devices from funeral homes have the potential for significant remaining longevity. METHODS: After sending letters asking funeral directors in the Philadelphia area to donate explanted pacemakers and defibrillators, 78 devices were recovered...

BACKGROUND: Current consensus guidelines suggest DOACs are interrupted peri-procedurally for catheter ablation (CA) of AF. However, this may predispose patients to thromboembolic complications. This study investigates the safety of CA for AF on uninterrupted DOACs compared to uninterrupted warfarin. METHODS: Single centre, retrospective study of consecutive patients undergoing CA for AF. All patients were heparinised prior to trans-septal puncture with a target activated clotting time (ACT) of 300-350 seconds...

BACKGROUND: Oral anticoagulation (OAC) is prescribed for left atrial thrombi (LAT) in non-rheumatic atrial fibrillation (AF) and/or atrial flutter (AFL). The study objective was to review the existing evidence regarding LAT resolution in non-rheumatic AF and/or AFL with OAC agents. METHODS: Data sources included PubMed, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) between January 1, 1991 and February 1, 2017. English-language studies that assessed LAT resolution with OAC agents in subjects with non-rheumatic AF and/or AFL, by serial transesophageal echocardiography (TEE), and with follow-up times ≥3 weeks and < 1 year were selected...

Although thought to be a rare event, permanent pacemakers and implantable cardioverter-defibrillators with right ventricular intracardiac leads have the potential to induce tricuspid valve dysfunction. Adverse lead-valve interactions can take place through a variety of mechanisms including damage at the time of implantation, leaflet pinning, or long-term fibrosis encapsulating the leaflet tissue. Clinical manifestations can display a wide range of severity, as well as a highly variable time span between implantation and hemodynamic deterioration...

REVIEW
Béatrice Brembilla-Perrot, Nicolas Girerd, Jean-Marc Sellal
many recent recommendations concern the management of pre-excitation syndrome. In clinical practice, they are sometimes difficult to use. The purpose of the authors was to discuss the main problems associated with this management. This article is protected by copyright. All rights reserved Three problems are encountered: 1) the reality of the absence of symptoms or the interpretation of atypical symptoms, 2) the electrocardiographic diagnosis of pre-excitation syndrome that can be missed and 3) the exact electrophysiological protocol and its interpretation used for the evaluation of the prognosis Because of significant progress largely related to the development of curative treatment, it seems easy to propose ablation in many patients despite the related risks of invasive studies and to minimize the invasive risk by only performing ablation for patients with at-risk pathways...

BACKGROUND AND OBJECTIVE: Worldwide adoption of the subcutaneous implantable cardioverter-defibrillator (S-ICD) for preventing sudden cardiac death continues to increase, as longer-term evidence demonstrating the safety and efficacy of the S-ICD expands. As a relatively new technology, comprehensive anesthesia guidance for the management of patients undergoing S-ICD placement is lacking. This article presents advantages and disadvantages of different peri-procedural sedation and anesthesia options for S-ICD implants including general anesthesia, monitored anesthesia care, regional anesthesia, and nonanesthesia personnel administered sedation and analgesia...

BACKGROUND: Patients with ventricular tachycardia (VT) post myocardial infarction (MI) are a higher risk group with significant morbidity and mortality. We examined the impact of prior coronary revascularization on clinical outcomes in patients with ischemic cardiomyopathy (ICM) and VT. METHODS: The VANISH trial randomized 259 patients with prior MI and antiarrhythmic drug-refractory VT to receive escalated medical therapy or catheter ablation. Clinical outcomes were compared according to whether patients have undergone prior revascularization procedures...

BACKGROUND: Our objective was to investigate trends over time in longevity and reasons for replacement with or without extraction of pacemaker leads after first implantation. METHODS: Data collected between 1984 and 2006 in the national Dutch pacemaker registry were used. This registry covered 84% of sold leads. First lead replacement with or without extraction of one or more leads implanted with a first pacemaker generator was the endpoint of interest. The time interval of and reason for first replacement were analysed...

A 72-year-old man who underwent a left atrial appendage (LAA) closure device two years ago, presented with atrial flutter with rapid ventricular rate and was referred for cardioversion. Pre-cardioversion transesophageal echocardiogram (TEE) showed left atrial thrombus and therefore the procedure was aborted. Currently, there is no guideline on imaging surveillance or anticoagulation in patients with LAA closure device who develop intracardiac thrombus after the initial six month surveillance period.

Aaron B Hesselson
BACKGROUND: Methodology specific for moving superficial chronically implanted trans-venous pacing leads to a sub-pectoral pocket is not described in the literature. Relocation of pre-pectoral leads and generator to a sub-muscular pocket for relief of erosion and pain with minimal pectoral trauma is possible by applying a variant of a previously described sub-mammary tunneling technique. METHODS: All patients presenting for device follow-up, elective battery replacement, or system upgrade over an 8-month period were considered for relocation if experiencing significant thinning or pain over their pre-pectoral implant...

BACKGROUND: The left ventricular papillary muscles are important components of the mitral valve apparatus. Catheter ablation of ventricular arrhythmias from these sites is challenging. We aim to describe the association between LV papillary muscle ventricular arrhythmias (VAs) and mitral valve prolapse (MVP), and to determine the outcomes of ablation in these patients with a focus on those with MVP and cardiomyopathy. METHODS: 152 patients underwent 170 consecutive procedures for ablation of focal VAs...
