Biventricular myocardial strain analysis using cardiac magnetic resonance feature tracking (CMR-FT) in patients with distinct types of right ventricular diseases comparing arrhythmogenic right ventricular cardiomyopathy (ARVC), right ventricular outflow-tract tachycardia (RVOT-VT), and Brugada syndrome (BrS).

Clin Res Cardiol 2019 Mar 13. Epub 2019 Mar 13.

Department of Clinical Radiology, University Hospital Muenster, Muenster, Germany.

Objectives: As underlying heart diseases of right ventricular tachyarrhythmias, ARVC causes wall-motion abnormalities based on fibrofatty myocardial degeneration, while RVOT-VT and BrS are thought to lack phenotypic MR characteristics. To examine whether cardiac magnetic resonance (CMR) feature tracking (FT) in addition to ARVC objectively facilitates detection of myocardial functional impairments in RVOT-VT and BrS.

Methods: Cine MR datasets of four retrospectively enrolled, age-matched study groups [n = 65; 16 ARVC, 26 RVOT-VT, 9 BrS, 14 healthy volunteers (HV)] were independently assessed by two distinctly experienced investigators regarding myocardial function using CMR-FT. Read More

Ventricular conduction stability test: a method to identify and quantify changes in whole heart activation patterns during physiological stress.

Europace 2019 Feb 28. Epub 2019 Feb 28.

National Heart & Lung Institute, Imperial College London, London, UK.

Aims: Abnormal rate adaptation of the action potential is proarrhythmic but is difficult to measure with current electro-anatomical mapping techniques. We developed a method to rapidly quantify spatial discordance in whole heart activation in response to rate cycle length changes. We test the hypothesis that patients with underlying channelopathies or history of aborted sudden cardiac death (SCD) have a reduced capacity to maintain uniform activation following exercise.

Sleep Fainting: A Neurocardiogenic Entity.

Cureus 2018 Dec 18;10(12):e3751. Epub 2018 Dec 18.

Cardiology, Aga Khan University Hospital, Karachi, PAK.

Fainting is a common clinical presentation, with vagally mediated (neurocardiogenic) causes being the most common for syncope presentation to the emergency room, and for hospital admissions. Classic teaching is that upright posture is a prerequisite for vagally mediated syncope (VMS) and that syncope in the supine position has more sinister causes. We present five patients, three males and two females, with a mean age of 44. Read More

Sudden cardiac death in football players: Towards a new pre-participation algorithm.

Exp Ther Med 2019 Feb 30;17(2):1143-1148. Epub 2018 Nov 30.

Exercise Physiology and Sports Medicine Clinic, Center for Adolescent Medicine and UNESCO Chair on Adolescent Health Care, First Department of Pediatrics, Medical School, National and Kapodistrian University of Athens, Aghia Sophia Children's Hospital, 11527 Athens, Greece.

Athletic pre-participation screening is essential for minimizing the risk for sudden cardiac death (SCD) in athletes participating in either competitive or leisure sporting activities. The primary causes of SCD in young athletes (<35 years of age) include hypertrophic cardiomyopathy, congenital anomalies of the coronary artery and arrhythmogenic right ventricular cardiomyopathy. Other abnormalities, such as malignant arrhythmia due to blunt trauma to the chest (commotio cordis), myocarditis, valvular disease, aortic rupture (in Marfan syndrome) and ion channelopathies (catecholaminergic polymorphic ventricular tachycardia, Brugada syndrome, long or short QT syndrome), also contribute to a lesser degree to SCD.

Early repolarization and risk of lone atrial fibrillation.

J Cardiovasc Electrophysiol 2019 Jan 19. Epub 2019 Jan 19.

Department of Cardiovascular Biology and Medicine, Niigata University Graduate School of Medical and Dental Sciences, Niigata, Japan.

Introduction: Early repolarization syndrome is a recently proposed condition characterized by an early repolarization pattern in the electrocardiogram (ECG) and ventricular fibrillation in the absence of structural heart abnormalities. Although some studies have suggested that early repolarization is associated with frequency of atrial fibrillation, the association of early repolarization with atrial fibrillation is not well known.

Hypothesis: Early repolarization indicates the substrate for atrial fibrillation in addition to that for ventricular fibrillation. Read More

Recently, alterations in the gene have been associated with different inherited cardiac conditions including Arrythmogenic Cardiomyopathy (ACM or ARVC), Brugada syndrome (BrS), and idiopathic ventricular fibrillation to name the most relevant. However, the assessment of pathogenicity regarding the genetic variations associated with is still a challenging task: the gene has a positive Residual Variation Intolerance Score and the potential deleterious role of several of its variants has been disputed.

ST-segment elevation and the Tpeak-Tend/QT ratio predict the occurrence of malignant arrhythmia events in patients with vasospastic angina.

J Electrocardiol 2019 Jan 3;53:52-56. Epub 2019 Jan 3.

Department of Cardiology, People's Hospital of Zhengzhou University (Henan provincial people's hospital), Fuwai Central China Cardiovascular Hospital, Zhengzhou, Henan Province, China.

Background: ST-segment elevation (STE) and an increased Tpeak-Tend interval (Tp-e) have prognostic value for malignant arrhythmia events (MAEs) in patients with ST-segment elevation myocardial infarction (STEMI) and Brugada syndrome. Whether STE could predict MAEs and has an electrophysiological relationship with Tp-e in electrocardiogram (ECG) of vasospastic angina (VA) patients needs to be elucidated.

Methods: Sixty-five patients with VA and 23 patients with VA complicated by MAEs were enrolled. Read More

A three-dimensional computed model of ST segment abnormality in type 1 Brugada Pattern: A key role of right ventricular outflow tract orientation?

J Electrocardiol 2018 Dec 19;53:31-35. Epub 2018 Dec 19.

Department of Clinical and Experimental Medicine, University Hospital of Messina, Italy.

Since its first description, Brugada Syndrome is characterized by definite ECG abnormalities (J wave, elevated ST segment) confined in right precordial leads. Brugada Pattern (BP) could be found in one or more right precordial leads, at conventional or higher intercostal spaces. A recent study, conducted by our group, reported that slightly less than one half of patients with type 1 BP show a definite ST segment depression (≥0. Read More

Mechanisms and management of inappropriate therapy in subcutaneous implantable cardioverter defibrillators.

J Cardiovasc Electrophysiol 2018 Dec 21. Epub 2018 Dec 21.

Electrophysiology and Arrhythmia Service, Cardiology Division, Department of Medicine, Boston Medical Center, Boston, Massachusetts.

Subcutaneous implantable cardioverter defibrillators (S-ICDs) provide reliable defibrillation and have enhanced supraventricular tachycardia discrimination and fewer infection rates compared with traditional transvenous systems. However, inappropriate shocks remain a frequent problem. Herein, we review the various mechanisms of these inappropriate therapies, some of which are unique to S-ICDs, and propose an algorithm for preventing recurrences. Read More
