BACKGROUND: Seizures can lead to cardiac arrhythmias by a number of mechanisms including activation/inhibition of cortical autonomic centers, increase in vagal tone through activation of brainstem reflex centers, and respiratory failure. Ictal asystole (IA) is a potential mechanism underlying sudden unexpected death in epilepsy (SUDEP). We analyzed the clinical features of 5 patients who developed IA requiring pacemaker implantation. METHODS: Patients with ictal arrhythmias were identified from the video-telemetry and ambulatory EEG database at Greater Manchester Neurosciences Centre, as well as an independent epilepsy residential care facility...

BACKGROUND: In patients treated with transcatheter aortic valve implantation (TAVI), age is recognized as one of the most important risk factors. The aim of our study was to evaluate whether early and mid-term results of TAVI were worse in patients over 85 year old compared with the younger population. METHODS: From September 2010 to November 2015, 162 consecutive patients (mean age 78.4 ±7.1 years, 47.5 % females) underwent TAVI in our Institution. Patients were divided into two groups: 1) elderly (≥ 85 year old) and 2) younger patients (< 85 year old)...

AIMS: Supraventricular arrhythmias are a major cause of morbidity and mortality in adult patients with congenital heart disease (CHD). Intraoperative ablation offers an alternative for patients who failed ablation procedures or are requiring concomitant surgical intervention. We present our long-term results with the surgical treatment of arrhythmias in adults with CHD (ACHD) undergoing elective cardiac surgery and the clinical predictors for arrhythmia recurrence. METHODS AND RESULTS: Between 2002 and 2013, 80 consecutive patients with CHD, mean age of 39 years, underwent intraoperative ablation with monopolar irrigated radiofrequency during cardiac surgery procedures...

Bisoprolol is a drug that acts via the mechanism of specifically and selectively inhibiting the β1-adrenoreceptor in cardiac myocytes, and provides a pure reduction of heart rate without changing other cardiac parameters. It has long been clinically used to treat cerebrovascular and cardiovascular illnesses. However, there is little information available on whether the role of bisoprolol in the attenuation of ventricular remodeling is dependent upon the achievement of a target dose, and whether it must be used as a preferred option...

Transcatheter aortic valve implantation (TAVI) is nowadays a worldwide technique in the field of treating aortic stenosis. One of the main side effects linked to the technique are mostly attached to rhythm disturbances, such as atrioventricular (AV) and intraventricular blocks. Consequently, a pacemaker implantation is often required. That implantation rate is estimated between 8 and 30%, depending on the valve chosen. Thanks to main meta analysis on the subject, it has been managed to isolate the following risks factors for AV block development: preoperative right bundle branch block (RBBB: the most powerful element), complete AV block during the procedure, male gender, a so-called porcelain aorta, the absence of previous valvular surgery, the aortic annulus size (i...

Drawing on and extending the Foucaultian philosophical framework that Jeffrey Bishop develops in his masterful book, The Anticipatory Corpse: Medicine, Power, and the Care of the Dying, we undertake a sociological analysis of the neurological procedure-deep brain stimulation (DBS)-which implants electrodes in the brain, powered by a pacemaker-like device, for the treatment of movement disorders. Following Bishop's work, we carry out this analysis through a two-fold strategy. First, we examine how a multidisciplinary team evaluates candidates for this implant at a major medical center...

Transcatheter aortic valve implantation (TAVI) has become a safe and efficient alternative to cardiac surgery in patients with severe aortic stenosis. In many countries the number of performed TAVI procedures equals the number of surgical implantations. Indications for TAVI are becoming more liberal, allowing a wider spectrum of patients to benefit from the advantages of transcatheter therapy. Due to its invasive nature, TAVI is associated with some complications such as conduction disturbances. Although these disturbances are usually not lethal, they have a great influence on patients' state and long term-survival...

OBJECTIVES: Transcatheter aortic valve implantation (TAVI) is an established treatment for high-grade aortic valve stenosis in patients found unfit for open heart surgery. The method may cause cardiac conduction disorders requiring permanent pacemaker (PPM) implantation, and the long-term effect of PPM implantation remains ambiguous. Design One hundred sixty-eight patients who underwent TAVI from 2008 to 2012 were included. Patient characteristics, ECGs and PPM data were collected through medical records...

OBJECTIVES: Transcatheter aortic valve-in-valve implantation (ViV) is a new treatment for failing bioprostheses (BP) in patients with high surgical risk. However, comparative data, using standard repeat surgical aortic valve replacement (redo-SAVR), are scarce. We compared outcomes after ViV with those after conventional redo-SAVR in two European centres with established interventional programmes. METHODS: In-hospital databases were retrospectively screened for patients ≥60 years, treated for failing aortic BP...

OBJECTIVES: In high-risk patients with severe aortic stenosis, aortic valve replacement (AVR) with a sutureless Perceval prosthesis (SU-AVR) can be performed instead of conventional AVR or transcatheter aortic valve implantation. Little data are available regarding postoperative conduction disorders after SU-AVR. We aimed to determine the incidence and predictors of new-onset complete atrioventricular block (NO-AVB) requiring permanent cardiac stimulation following SU-AVR. METHODS: We studied consecutive patients who underwent SU-AVR between 2013 and 2015...

Atrial standstill is a rare disorder of cardiac rhythm that is characterized by total absence of electrical activity in one or both atria. We report herein the case of a patient with atrial fibrillation and symptomatic 4.0 s pauses who received a ventricular demand pacemaker. The patient later underwent mitral valve replacement with a pericardial tissue valve and the Cox-maze III procedure for symptomatic mitral stenosis and atrial fibrillation. Following surgery, he developed atrial standstill and became pacemaker dependent...
