In utero intervention for severe congenital heart disease.

Best Pract Res Clin Obstet Gynaecol 2019 Jan 17. Epub 2019 Jan 17.

The Fetal Center, Children's Memorial Hermann Hospital and the Department of Obstetrics and Gynecology, McGovern Medical School, UTHealth, Houston, TX, USA. Electronic address:

The aim of foetal cardiac therapy is to treat an abnormality at the developmental stage so that the process of cardiac growth, which is complex and relies on the volume and direction of circulating blood as well as genetic determinants, can continue. In reality, most cardiac interventions are palliative; hence, major abnormalities are still present at birth. Nevertheless, tangible benefits following successful foetal intervention include improved haemodynamics and reduction in secondary damage leading to better postnatal outcomes. Read More

Gallbladder: the Metabolic Orchestrator.

Diabetes Metab Res Rev 2019 Feb 15:e3140. Epub 2019 Feb 15.

Department of General Surgery, Shengjing Hospital of China Medical University, Shenyang, Liaoning Province, China.

It is commonly held that the gallbladder (GB) is not indispensable for life. However, recent studies strongly suggest that GB removal can lead to the development of metabolic syndrome (MetS). With the recent recognition of the role of bile acids (BAs) in systemic metabolic regulation, it is worthwhile to re-examine the function of the GB, which can be regarded as the physiological 'pacemaker' of BA flow.

Severe Bradycardia Prior to Coronary Artery Bypass Graft Surgery: A Case Report.

J Tehran Heart Cent 2018 Jul;13(3):136-139

Department of Cardiothoracic Surgery, Barts Heart Centre, St Bartholomew's Hospital, London, UK.

Intraventricular conduction abnormalities following cardiac surgery have been thoroughly described, especially after valvular surgery. It is also widely known that several anesthetic factors can cause autonomic disturbances resulting in the unmasking of sinus node dysfunction, significant bradycardia, and cardiovascular collapse during the intraoperative period. However, little is known about asymptomatic episodes, especially those occurring prior to coronary artery bypass grafting (CABG). Read More

Indications for permanent pacing in dogs and cats.

J Vet Cardiol 2019 Jan 29. Epub 2019 Jan 29.

Clinica Veterinaria Malpensa, Viale Marconi 27, 21017 Samarate, Varese, Italy.

Pacemaker implantation is considered as a standard procedure for treatment of symptomatic bradycardia in both dogs and cats. Advanced second-degree and third-degree atrioventricular blocks, sick sinus syndrome, persistent atrial standstill, and vasovagal syncope are the most common rhythm disturbances that require pacing to either alleviate clinical signs or prolong survival. Most pacemakers are implanted transvenously, using endocardial leads, but rarely epicardial leads may be necessary. Read More

Functional biological pacemaker generation by T-Box18 protein expression via stem cell and viral delivery approaches in a murine model of complete heart block.

Pharmacol Res 2019 Jan 21;141:443-450. Epub 2019 Jan 21.

Biotechnology Research Center, Pharmaceutical Technology Institute, Mashhad University of Medical Sciences, Tehran, Iran; Neurogenic Inflammation Research Center, Mashhad University of Medical Sciences, Tehran, Iran; School of Medicine, Mashhad University of Medical Sciences, Tehran, Iran.

Despite recent advances in the treatment of cardiac arrhythmia, the available options are still limited and associated with some complications. Induction of biological pacemakers via Tbx18 gene insertion in the heart tissue has been suggested as a promising therapeutic strategy for cardiac arrhythmia. Following a previous in vitro study reporting the production of Tbx18-expressing human induced pluripotent stem cell-derived cardiomyocytes (hiPS-CMs), we aimed to investigate the efficacy of these engineered cells to generate pacemaker rhythms in a murine model of complete heart block.

Familial Sinus Node Disease Caused by a Gain of GIRK (G-Protein Activated Inwardly Rectifying K Channel) Channel Function.

Circ Genom Precis Med 2019 Jan;12(1):e002238

Department of Cardiovascular Medicine, Institute for Genetics of Heart Diseases (IfGH), University Hospital Münster, Germany (J.K., B.S., S.Z., G.S., E.S.-B.).

Background: Inherited forms of sinus node dysfunction (SND) clinically include bradycardia, sinus arrest, and chronotropic incompetence and may serve as disease models to understand sinus node physiology and impulse generation. Recently, a gain-of-function mutation in the G-protein gene GNB2 led to enhanced activation of the GIRK (G-protein activated inwardly rectifying K channel). Thus, human cardiac GIRK channels are important for heart rate regulation and subsequently, genes encoding their subunits Kir3. Read More

The necessity of implantable cardioverter defibrillators in patients with Kearns-Sayre syndrome - systematic review of the articles.

Int J Cardiol 2019 Mar 27;279:105-111. Epub 2018 Dec 27.

Department of Pathophysiology, Oita University, 1397-1, Yamane, Hidaka, Saitama 350-1298, Japan.

The most common cardiac feature of Kearns-Sayre syndrome (KSS) is atrioventricular block (AVB), and pacemaker implantations (PMIs) are recommended for KSS patients with advanced AVB. However, some KSS patients develop fatal arrhythmias such as polymorphic ventricular tachycardia (PMVT) and ventricular fibrillation (VF) and die suddenly even after PMIs. We report a patient with KSS who developed PMVT, VF, and QT prolongation, and was treated with mexiletine and successfully managed with an implantable cardioverter defibrillator (ICD). Read More

Canine and human sinoatrial node: differences and similarities in the structure, function, molecular profiles, and arrhythmia.

J Vet Cardiol 2018 Dec 14. Epub 2018 Dec 14.

Department of Physiology and Cell Biology, Dorothy M. Davis Heart & Lung Research Institute, The Ohio State University Wexner Medical Center, Columbus, OH, USA. Electronic address:

The sinoatrial node (SAN) is the primary pacemaker in canine and human hearts. The SAN in both species has a unique three-dimensional heterogeneous structure characterized by small pacemaker myocytes enmeshed within fibrotic strands, which partially insulate the cells from aberrant atrial activation. The SAN pacemaker tissue expresses a unique signature of proteins and receptors that mediate SAN automaticity, ion channel currents, and cell-to-cell communication, which are predominantly similar in both species.

A Minimally Invasive Approach for Placing Sew-On Epicardial Leads in the Child.

Innovations (Phila) 2018 Nov/Dec;13(6):455-457

LSI SOLUTIONS, Victor, NY USA.

Traditionally, pacing leads are placed transvenously, although smaller pediatric patients who require permanent pacemakers may benefit from delaying tranvenous lead placement until they are larger. Alternative, minimally invasive atrioventricular pacing options have not previously existed for this patient population, leaving many of these children with large sternotomies or thoracotomies. Using three port sites and an adjustable shaft dual-needle suturing device, we placed a steroid-eluting, sew-on epicardial lead on the right atrium of a 9-year-old patient. Read More

North Clin Istanb 2018 12;5(2):96-101. Epub 2018 Apr 12.

Department of Cardiology, Acibadem Atakent University Hospital, Istanbul, Turkey.

Objective: Technological advances have allowed cardiac implantable electronic devices (CIEDs) to detect, analyze, and store atrial high-rate episodes (AHREs), which are surrogate for the term silent atrial fibrillation (AF). The association of AHREs with adverse clinical events has been demonstrated in several recent studies, implying that morbidity and mortality can be significantly prevented by prompt recognition and intervention. Inflammation and oxidative stress are among several mechanisms that contribute to the pathogenesis of AF. Read More

Authors:
S Oebel G Hindricks

Herz 2018 Dec;43(8):701-709

Abteilung für Rhythmologie, HELIOS Herzzentrum Leipzig, Strümpellstraße 39, 04289, Leipzig, Deutschland.

Syncope is a common problem in clinical practice, which affects approximately 1% of patients admitted to European emergency departments. The clinical practice guidelines for the diagnosis and management of syncope published by the European Society of Cardiology (ESC) are based on the newest scientific data in the field and have provided clinical cardiologists with a structured therapeutic approach for affected patients over many years. The previous ESC guidelines on syncope were published in 2009 and are compared to the most recent edition, which was published in 2018. Read More

Safety and efficacy of AAIR pacing in selected patients with sick sinus syndrome.

Medicine (Baltimore) 2018 Oct;97(42):e12833

Division of Cardiology, Grey Nuns Community Hospital, Edmonton, Alberta, Canada.

Background: The DANPACE study suggested implanting dual-pacing dual-sensing dual-response rate-adaptive (DDDR) pacemakers in patients with sick sinus syndrome, even though 90.7% of their atrial-pacing atrial-sensing inhibited-response rate-adaptive (AAIR) group did not require upgrade. Most centers implant DDDR pacemakers due to risk of future atrioventricular (AV) block. Read More

Takotsubo syndrome with severe bradycardia initiated by seizure: Is the implantation of a permanent pacemaker necessary?

BMJ Case Rep 2018 Oct 12;2018. Epub 2018 Oct 12.

Department of Cardiovascular Medicine, Nippon Medical School, Bunkyo-ku, Tokyo, Japan.

Although arrhythmias are frequent in patients with Takotsubo syndrome (TTS), data on sick sinus syndrome remain elusive. Here, we report a case of TTS initiated by a seizure as a physical trigger that led to sinus arrest. The patient presented with cardiogenic shock and bradycardia which required intensive cardiovascular care. Read More

Leadless pacing in a patient with superior vena cava syndrome undergoing lead extraction and percutaneous angioplasty.

J Cardiol Cases 2018 Jun 30;17(6):212-214. Epub 2018 Mar 30.

Cardiac Thoracic and Vascular Department - AOUP, Santa Chiara University Hospital, Pisa, Italy.

Superior vena cava (SVC) syndrome is an uncommon but serious complication associated with chronic transvenous implanted leads. In the recent past, open-heart surgery combining lead extraction and epicardial implant was usually performed to reduce syndrome recurrences. We describe the case of a 78-year-old man successfully treated by percutaneous lead extraction associated with venous balloon angioplasty and reimplantation of leadless pacemaker. Read More

Incorrect Holter-ECG analysis caused by the pacemaker delivering small high-frequency currents for thoracic impedance measurement.

J Cardiol Cases 2017 Dec 12;16(6):219-222. Epub 2017 Sep 12.

Department of Cardiology, Kido General Hospital, Niigata, Japan.

In an 86-year-old woman who had been treated for sick sinus syndrome, the small high-frequency current delivered by pacemaker in order to measure the minutes ventilation for utilizing the rate-response mode was transiently over-sensed on the Holter electrocardiogram. Although her pacing system was working appropriately, the numbers of the paced beats on the automatic Holter analysis were undercounted (from >60% to <5%) during the over-sensing periods because these currents were recognized as multiple pacing spikes. Physicians need to pay attention to such multiple pacing spike markers, because these can be a cause of unreliable results of the Holter analysis. Read More
