BACKGROUND: Iliofemoral arterial disease can preclude transfemoral (TF) transcatheter aortic valve replacement (TF-TAVR). Transthoracic access by direct aortic or a transapical approach imparts a greater risk of complications and death than TF access. We hypothesized that subclavian/axillary arterial (SCA) access offers equivalent risks and outcomes as TF access. METHODS: The outcomes of 202 patients from the CoreValve (Medtronic, Minneapolis, MN) United States Pivotal Trial Program treated with SCA access were propensity matched with patients treated with TF access and analyzed...

BACKGROUND: Cardiac Resynchronization therapy (CRT) remains largely under-used in developing countries owing to the high cost of therapy. In this pilot study, we explore 'optimized' Left Ventricle Only Pacing (LVOP) as a cost effective alternative to cardiac resynchronization therapy in selected patients with heart failure. HYPOTHESIS: In economically poorer patients with heart failure, left bundle branch block (LBBB) and intact AV node conduction, synchronization can be obtained using a dual chamber pacemaker (leads in right atrium and Left ventricle) with the help of 2D strain imaging...

Many disorders are manifested by dysfunction of key cell types or their disturbed integration in complex organs. Thereby, adult organ systems often bear restricted self-renewal potential and are incapable of achieving functional regeneration. This underlies the need for novel strategies in the field of cell (re-)programming-based regenerative medicine as well as for drug development in vitro. The regenerative field has been hampered by restricted availability of adult stem cells and the potentially hazardous features of pluripotent embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs)...

We report a 69-year-old female patient with advanced lung cancer who developed myocarditis concomitant with myasthenia gravis (MG), also known as "Herzmyasthenie," after 3 cycles of nivolumab administration. Her initial symptoms were general malaise and double vision. However, her myocarditis deteriorated rapidly the following day, necessitating a temporary pacemaker and noninvasive positive pressure ventilation in the intensive care unit. Immunohistochemical examination of a myocardial biopsy suggested an immune response on the basis of HLA associations...

Although new pacemakers can register cardiac rhythm, few studies were performed evaluating their accuracy in diagnosing ventricular arrhythmias (VA). This study aimed to assess the correlation and agreement between the pacemaker's monitor and the ambulatory Holter in detecting VA. METHODS/RESULTS: We studied 129 patients with pacemakers, mean age 68.6±19.1 years, 54.8% female. Once Holter monitoring was connected, the pacemakers' event counters were reset and clocks of both systems were synchronized to register ECG simultaneously...

PURPOSE OF REVIEW: Patients with cardiac implantable electronic devices (CIEDs) frequently undergo various surgical procedures and in the past perioperative management involved only placing magnet over the device. New programming features, development of implantable cardiac defibrillator (ICD), cardiac resynchronization therapy, and increasing complexity of the operating room equipment have led to new sources of electromagnetic interference (EMI). A comprehensive understanding of the CIED is necessary to provide a timely and optimal care to the patients...

BACKGROUND: Most outpatient follow-ups after pacemaker implantation do not involve changes in the device settings. Moreover, the need for pacemaker reprogramming declines with time after implantation. Currently, data on the need for changes in pacemaker set-up after replacement owing to battery depletion are lacking. The aim of this study was to determine the rates of pacemaker reprogramming in this patient group. METHODS: A retrospective analysis was performed using the files of 217 patients who had undergone pacemaker replacement between 2002 and 2005...

Adult cardiomyocytes (CMs) possess a highly restricted intrinsic regenerative potential - a major barrier to the effective treatment of a range of chronic degenerative cardiac disorders characterized by cellular loss and/or irreversible dysfunction and which underlies the majority of deaths in developed countries. Both stem cell programming and direct cell reprogramming hold promise as novel, potentially curative approaches to address this therapeutic challenge. The advent of induced pluripotent stem cells (iPSCs) has introduced a second pluripotent stem cell source besides embryonic stem cells (ESCs), enabling even autologous cardiomyocyte production...

INTRODUCTION: Cardiac Resynchronization Therapies (CRTs) have been demonstrated to improve the clinical management and prognosis of selected patients with heart failure. EVIDENCE ACQUISITION: CRT devices include both CRT Pacemakers (CRT-P) and CRT defibrillators (CRT-D), with the latter being used to treat life-threatening ventricular arrhythmias. EVIDENCE SYNTHESIS: A significant advantage of CRTs is the ability to monitor several vital parameters which, thanks to advanced technology, may be remotely assessed...

INTRODUCTION: Recovery of conduction has been demonstrated in >50% of patients who receive pacemakers (PPMs) for high-degree atrioventricular block (HD-AVB) after transcatheter aortic valve replacement (TAVR). Little information is available about the time course of conduction recovery in these patients and if any features predict early recovery of conduction. METHODS: A retrospective review was performed of patients who underwent TAVR with balloon and self-expanding valves who required PPMs for HD-AVB...

A 58-year-old woman received a dual chamber pacemaker (Medtronic) for sick sinus syndrome. Given intact AV conduction the Managed Ventricular Pacing mode algorithm (MVP) was programmed. The day after, she suffered from palpitations. Her ECG showed a possible loss of atrial capture accompanied by atrial undersensing. Telemetry-supported pacemaker control confirmed the loss of capture. Undersensing of atrial signal was functional, related to long atrial refractory period in MVP mode algorithm. Device algorithms could induce false suspicions...
