Temporary pacing

Chia-Feng Liu, William E Samsa, Guang Zhou, Véronique Lefebvre
A milestone in the evolutionary emergence of vertebrates was the invention of cartilage, a tissue that has key roles in modeling, protecting and complementing the bony skeleton. Cartilage is elaborated and maintained by chondrocytes. These cells derive from multipotent skeletal progenitors and they perform highly specialized functions as they proceed through sequential lineage commitment and differentiation steps. They form cartilage primordia, the primary skeleton of the embryo. They then transform these primordia either into cartilage growth plates, temporary drivers of skeletal elongation and endochondral ossification, or into permanent tissues, namely articular cartilage...

: Transcatheter aortic valve implantation (TAVI) and balloon aortic valvuloplasty (BAV) are now well established percutaneous procedures. These procedures almost always require bursts of rapid ventricular pacing to temporarily reduce cardiac output to facilitate the procedure, usually done via a temporary pacing wire inserted into the right ventricle. We describe a case series of 132 cases of TAVI and 76 BAV done using ventricular pacing via the left ventricular lead by simply connecting one electrode to the patient's skin and one electrode through the left ventricular (LV) wire...

Reversible complete atrioventricular block in patient with Wegener's granulomatosis - a report on a positive outcome with long term follow-up. Atrioventricular (AV) block is a rare complication of Wegener's granulomatosis (WG), thus there are no standards of management in such cases. We present a case of a patient with a dual-chamber pacemaker (DDD) implanted due to complete AV block in the course of Wegener's granulomatosis (WG). An immunosuppressive therapy resulted in the resolution of non-cardiac and AV conduction disorders...

Temporary epicardial pacing wires during open-heart surgery are routinely used both for diagnostic and treatment purposes. In complicated cases where patients are unstable or the wires are difficult to remove, the pacing wires are cut at the skin level and allowed to retract by themselves. This procedure rarely causes complications. However, there have been cases reporting that retained pacing wires are linked to the formation of sterno-bronchial fistulae, which may present a while after the date of operation and are usually infected...

BACKGROUND: Radiofrequency identification (RFID) detection systems are used to detect retained surgical sponges and may cause electromagnetic interference (EMI), altering intended function of cardiac pacing systems. Three pediatric patients requiring temporary pacing for postoperative atrioventricular block experienced transient inhibition of ventricular pacing during the use of RFID detection system. Bench testing was performed to evaluate the mechanism of pacemaker inhibition. METHODS: Impedance of temporary pacing wires was obtained using a pacing system analyzer...

Arrhythmic management is needed after removal of cardiac implantable electronic devices (CIEDs). Patients completely dependent on CIEDs need temporary device back-up until new CIEDs are implanted. Various methods are available for device back-up, and the appropriate management varies among patients. The duration from CIED removal to implantation of a new CIED also differs among patients. Temporary pacing is needed for patients with bradycardia, a wearable cardioverter defibrillator (WCD) or catheter ablation is needed for patients with tachyarrhythmia, and sequential pacing is needed for patients dependent on cardiac resynchronization therapy...

Parkinson's disease [PD] is the second most common neurodegenerative disorder after Alzheimer's disease, affecting 1% of the population over the age of 55. The underlying neuropathology seen in PD is characterised by progressive loss of dopaminergic neurons in the substantia nigra pars compacta with the presence of Lewy bodies. The Lewy bodies are composed of aggregates of α-synuclein. The motor manifestations of PD include a resting tremor, bradykinesia, and muscle rigidity. Currently there is no cure for PD and motor symptoms are treated with a number of drugs including levodopa [L-dopa]...

Maternal complete heart block can pose significant challenges for the anesthesiologist in the antepartum, peripartum, and postpartum periods. Some patients may present for the first time in the puerperium with dizziness, weakness, syncope, or congestive heart failure as a result of the additional hemodynamic burden that accompanies pregnancy. Although there is an increase in permanent pacemaker placement in young symptomatic patients before pregnancy, prophylactic placement of pacemakers in asymptomatic parturients is not always indicated...

BACKGROUND: Radiofrequency (RF) technology has improved detection of retained surgical sponges with a reported 100% sensitivity and specificity. However, the potential for interactions of the RF signals emitted by the detection system with cardiac implantable electronic devices (CIEDs) or temporary pacemakers may limit its use in those patients with these devices. This study investigated whether RF detection technology causes interference or clinically significant changes in the programmed settings of implanted pacemakers and defibrillators or temporary epicardial pacemakers...

BACKGROUND: Many patients with atrial fibrillation (AF) or atrial flutter (Aflutter) have concomitant sinus node dysfunction (SND). Ablation may result in injury to the sinus node complex or its blood supply resulting in sinus arrest and need for temporary pacing. We sought to characterize patients who develop acute SND (ASND) during/immediately after AF/Aflutter ablation. METHODS: We performed a retrospective analysis of AF/Aflutter ablation patients between January 1, 2010 and February 28, 2015 to characterize those who required temporary pacemaker (TPM) implantation due to ASND (sinus arrest, sinus bradycardia <40 beats/min, or junctional rhythm with hemodynamic compromise) following atrial ablation...

OBJECTIVES: We sought to demonstrate the safety and efficacy of rapid left ventricular (LV) pacing through the guidewire during balloon aortic valvuloplasty (BAV) and Transaortic valve implantation (TAVI). BACKGROUND: Right ventricular temporary pacing during TAVI and BAV is time-consuming and associated with vascular and pericardial complications. METHODS: Rapid left ventricular pacing was provided via the back-up 0.035″ guidewire. The cathode of an external pacemaker was placed on the tip of the 0...

INTRODUCTION: Several reports have indicated that left ventricular (LV) lead placement at an optimal pacing site is an important determinant of short- and long-term outcome. This study investigated the effect of pacing mode (atrioventricular [AV] or ventricular) and site (LV apical or lateral) outside the ischemic region on the LV hemodynamic, torsional and strain indices in the ischemic myocardium. METHODS: Experiments were conducted in anesthetized open-chest pigs (n = 15) 30 min after LAD ligation to investigate the hemodynamic effects of temporary epicardial AV and ventricular LV pacing at the LV apical (outside the ischemic region) or lateral wall...

A 48-year-old man was refered to our hospital for the treatment of bicusp aortic valve and severe aortic regurgitation. He underwent Bentall procedure (SJM 25mm+HemashieldØ 28 mm composite graft). Temporary epicardial pacing lead( TPL) was placed on the right ventricle at the opetation, and was cut on his skin surface prior to discharge because of difficulty in traction removal. After 15 years from operation, follow up computered tomography and echocardiography showed migration of 2 retaining TPLs extending from vascular graft of ascending aorta to the right innominate artery...

BACKGROUND: Botulinum toxin (BTX), temporarily suppressing cholinergic transmission (<3 weeks), has been reported to suppress atrial fibrillation (AF) for ≥1 year. We aimed to investigate the mechanism underlying long-term suppression of AF caused by injecting BTX into major atrial ganglionated plexi (GPs). METHODS AND RESULTS: Bilateral thoracotomies in anesthetized dogs allowed programmed stimulation at 4 pulmonary veins, biatrial appendages, and the superior vena cava to determine the effective refractory period (ERP) in the first operation...

BACKGROUND: Conventional pacemaker therapy is limited by short- and long-term complications, most notably device infection. Transcatheter pacing systems (TPS) may be beneficial in this kind of patients as they eliminate the need for a device pocket and leads and thus may reduce the risk of re-infection. METHODS: We assessed a novel procedure in 6 patients with severe device infection who were pacemaker dependent. After lead extraction a single chamber TPS was implanted into the right ventricle...

Therapeutic gene transfer holds the promise of providing lasting therapies and even cures for diseases that were previously untreatable or for which only temporary or suboptimal treatments were available. For some time, clinical gene therapy was characterized by some impressive but rare examples of successes and also several setbacks. However, effective and long-lasting treatments are now being reported from gene therapy trials at an increasing pace. Positive outcomes have been documented for a wide range of genetic diseases (including hematological, immunological, ocular, and neurodegenerative and metabolic disorders) and several types of cancer...
