BACKGROUND: The goal was to test the effectiveness of a structured pain management programme after invasive electrophysiological interventions in cardiology including ablation of atrial fibrillation (AF) or ventricular tachycardia (VT) and implantation, or explantation, of pacemakers or implantable cardioverter defibrillators. METHODS: This was a prospective study with a pre-/post-design where a post-intervention group (116 consecutive patients) was compared to a pre-intervention group (102 consecutive patients) after implementation of a structured pain-management programme using the numeric rating scale (NRS 0-10) and classified as moderate-to-severe if NRS > 3...

Long term ECG monitoring has become nowadays an indispensable technology for prevention, management and treatment of many cardiac issues. Today long term ECG monitoring is achievable through loop recorders (LR) and cardiac devices (CIED) like pacemaker (PM), implantable cardioverter-defibrillators (ICDs) and cardiac resynchronization therapy device-defibrillators (CRT- Ds), all of which associated with remote monitoring (RM). Targeted long term ECG monitoring Patients who have recurrent non documented episodes of palpitations, unexplained episodes of syncope, cryptogenic stroke or patients with a cardiomiopathy needing a risk stratification, may benefit from long term ECG monitoring...

OBJECTIVE: To determine the incremental value of implantable cardioverter defibrillators (ICD) in contemporary optimally treated patients with heart failure (HF) undergoing cardiac resynchronisation therapy (CRT). METHODS: Consecutive patients with HF undergoing CRT-pacemaker (CRT-P) or CRT-defibrillator (CRT-D) implantation in a single tertiary care centre between October 2008 and August 2015 were retrospectively evaluated. For patients with a primary prevention indication of the CRT-D, no benefit of the ICD was defined as absence of appropriate therapy (device analysis) or lethal ventricular tachyarrhythmias (mode of death analysis) during follow-up...

BACKGROUND: Detection of paroxysmal atrial fibrillation (PAF) in cryptogenic stroke is critical to selecting an antithrombotic therapy for preventing recurrent stroke. However, the predictor of PAF in patients with acute ischemic stroke is not well elucidated. P-wave terminal force in lead V1 (PTFV1) is a standard electrocardiogram marker of left atrial abnormality. In this study, we aimed to investigate the utility of PTFV1 for the prediction of PAF in patients with acute ischemic stroke...

Magnetic resonance imaging (MRI) is the preferred modality for soft tissue imaging because of its nonionizing radiation and lack of contrast agent. Due to interactions between the MR system and active implantable medical devices (AIMDs), patients with implants such as pacemakers are generally denied access to MRI, which presents a detriment to that population. It has been estimated that 50-75% of patients with a cardiac device were denied access to MRI scanning and, moreover, that 17% of pacemaker patients need an MRI within 12 months of implantation [1]...

BACKGROUND: The clinical characteristics of ischemic stroke in patients with a pacemaker (PM) are not well understood. METHODS: Forty-six ischemic stroke patients with a PM were investigated retrospectively, and the impact of different pacing modes was compared. RESULTS: The patients were divided into a physiological pacing group (n = 22) and a ventricular pacing group (n = 24). The prevalence of atrial fibrillation (AF) was significantly higher in the ventricular pacing group (36% versus 75%; P = ...

BACKGROUND: Double inlet left ventricle (DILV) is a heterogeneous single ventricle anomaly in which initial presentation, and consequently, timing and palliation mode vary based on morphology and degree of pulmonary or systemic outflow obstruction. Very few reports, mostly old, focused on palliation outcomes of DILV. We report current-era results and examine whether morphologic and subsequently surgical factors influence survival. METHODS: Fifty-eight infants with DILV underwent single ventricle palliation...

Tricuspid valve stenosis (TS) is rare, affecting less than 1% of patients in developed nations and approximately 3% of patients worldwide. Detection requires careful evaluation, as it is almost always associated with left-sided valve lesions that may obscure its significance. Primary TS is most frequently caused by rheumatic valvulitis. Other causes include carcinoid, radiation therapy, infective endocarditis, trauma from endomyocardial biopsy or pacemaker placement, or congenital abnormalities. Surgical management of TS is not commonly addressed in standard cardiac texts but is an important topic for the practicing surgeon...

Cardiac implantable electronic devices are frequently encountered in clinical practice in patients being screened for MR imaging examinations. Traditionally, the presence of these devices has been considered a contraindication to undergoing MR imaging. Growing evidence suggests that most of these patients can safely undergo an MR imaging examination if certain conditions are met. This document will review the relevant cardiac implantable electronic devices encountered in practice today, the background physics/technical factors related to scanning these devices, the multidisciplinary screening protocol used at our institution for scanning patients with implantable cardiac devices, and our experience in safely performing these examinations since 2010...

Amyloidosis covers a group of disorders that can manifest in virtually any organ system in the body and is thought to be secondary to misfolding of extracellular proteins with subsequent deposition in tissues. The precursor protein that is produced in excess defines the specific amyloid type. This requires histopathological confirmation using Congo-red dye with its characteristic demonstration of green birefringence under cross-polarized light. There are three main types of amyloidosis associated with cardiac involvement: light-chain (AL), familial or senile (ATTR), and secondary (AA) amyloidosis...

Hyperpolarization-activated cyclic-nucleotide gated channel (HCN) proteins are important regulators of both neuronal and cardiac excitability. Among the 4 HCN isoforms, HCN4 is known as a pacemaker channel, because it helps control the periodicity of contractions in vertebrate hearts. Although the physiological role of HCN4 channel has been studied in adult mammalian hearts, an earlier role during embryogenesis has not been clearly established. Here, we probe the embryonic roles of HCN4 channels, providing the first characterization of the expression profile of any of the HCN isoforms during Xenopus laevis development and investigate the consequences of altering HCN4 function on embryonic pattern formation...

The clinical impact of left ventricular (LV) segmental wall motion abnormalities (SWMA) in patients with idiopathic dilated cardiomyopathy (IDCM) has not been well elucidated.Among 100 consecutive IDCM patients with follow-up visits, we enrolled 85 after excluding those with left bundle branch block and/or ventricular pacemaker implantation. LV wall motion was assessed using left ventriculography scored for 7 segments according to the American Heart Association classification as follows: 0, normokinesis; 1, hypokinesis; 2, akinesis; and 3, dyskinesis...

Leadless pacemaker (LP) technology was recently developed and introduced for clinical purpose as an alternative to traditional systems in order to reduce leads and pocket-related complications. Currently, two self-contained right ventricular pacemaker implanted by using a femoral percutaneous approach have been developed and initial results seem promising. Although the clinical use is still limited to the right ventricular pacing, the LP currently represents a valid and alternative solution in several settings, when the standard pacemaker cannot be used or its use is associated with higher risk of complications...

Atrioventricular node ablation (AVNA) is generally reserved for patients whose atrial fibrillation (AF) is refractory all other therapeutic options, since the recipients will often become pacemaker dependent. In such patients, this approach may prove particularly useful, especially if a tachycardia-induced cardiomyopathy is suspected. Historically, an "ablate and pace" approach has involved AVNA and right ventricular pacing, with or without an atrial lead. There is also an evolving role for atrioventricular node ablation in patients with AF who require cardiac resynchronization therapy for treatment of systolic heart failure...

Vasovagal reaction, resulting in bradycardia and/or hypotension in response to a number of stimuli, is usually self limitant, but potentially life-threatening exceptions have been described. Pharmacological treatment of proven efficacy is still lacking and the administered compounds are often chosen on the basis of either case reports or outdated small studies with a short-term follow up. In refractory cases, pacemaker implantation may be considered, although no responder patients represent a severe challenge for clinicians...
