High-Risk Cardiovascular Conditions in Sports-Related Sudden Death: Prevalence in 5,169 Schoolchildren Screened via Cardiac Magnetic Resonance.

Tex Heart Inst J 2018 08 1;45(4):205-213. Epub 2018 Aug 1.

Improving preparticipation screening of candidates for sports necessitates establishing the prevalence of high-risk cardiovascular conditions (hr-CVC) that predispose young people to sudden cardiac death (SCD). Our accurate, novel protocol chiefly involved the use of cardiac magnetic resonance (CMR) to estimate this prevalence. Middle and high school students from a general United States population were screened by means of questionnaires, resting electrocardiograms, and CMR to determine the prevalence of 3 types of hr-CVC: electrocardiographic abnormalities, cardiomyopathies, and anomalous coronary artery origin from the opposite sinus with intramural coronary course (ACAOS-IM).

Ebstein's Anomaly of the Tricuspid Valve: A Natural Laboratory for Re-Entrant Tachycardias.

Authors:
Edward P Walsh

JACC Clin Electrophysiol 2018 Oct 25;4(10):1271-1288. Epub 2018 Jul 25.

Cardiac Electrophysiology, Boston Children's Hospital, Harvard Medical School, Boston, Massachusetts. Electronic address:

Ebstein's anomaly of the tricuspid valve is a relatively rare form of congenital heart disease that has long been a challenge to electrophysiologists and cardiac surgeons. In addition to the hemodynamic burden of the actual valve defect, Ebstein's patients must also contend with an extraordinarily high incidence of tachyarrhythmias, most of which can be attributed to accessory atrioventricular pathways (APs) located along the posterior and septal border of the tricuspid valve where the valve leaflets are most abnormal. It is the only congenital heart defect with such a dramatic predisposition toward APs. Read More

Department of Pathology, National Cerebral and Cardiovascular Center, Osaka, Japan.

Myocardial bundles working as accessory pathways in Wolff-Parkinson-White (WPW) syndrome are generally tiny tissues, so elucidating the culprit histology of atrioventricular (AV) myocardial connections requires careful serial sectioning of the AV junction. We performed a postmortem examination of accessory AV myocardial connections in an 84-year-old man who died from pneumonia 20 years after surgical cryoablation for WPW syndrome. Three-dimensional reconstruction images of serial histologic sections revealed accessory AV connections between the atrial and ventricular myocardium in the vicinity of the cryoablation scar.

Antidromic Atrioventricular Reentry Tachycardia with Wolff Parkinson White Syndrome: A Rare Beast.

Cureus 2018 May 17;10(5):e2642. Epub 2018 May 17.

Cardiology Department, Charleston Area Medical Center/west Virginia University.

Orthodromic atrioventricular reentrant tachycardia (AVRT) is the second-most-common form of supraventricular tachycardia (SVT) and is inducible in approximately 55% of individuals with Wolff Parkinson White (WPW) syndrome. Antidromic AVRT, where the accessory atrioventricular connection is used as the antegrade limb and the atrioventricular node serves as the retrograde limb of the circuit, has been clinically documented in less than 5% of patients with WPW syndrome and may be induced in less than 10% of these WPW cases in the electrophysiology laboratory. Left lateral pathways are considered more frequent and septal locations are less common when associated with antidromic AVRT. Read More

Wide QRS complex supraventricular tachycardia with negative precordial concordance: Electrocardiographic clues for Mahaim pathway with Ebstein anomaly.

J Electrocardiol 2018 Jul - Aug;51(4):663-666. Epub 2018 Apr 12.

Health Science University, Turkiye Yuksek Ihtisas Training and Research Hospital, Department of Electrophysiology, Ankara, Turkey.

Ebstein's anomaly is often accompanied by either Wolff-Parkinson-White syndrome or atriofascicular Mahaim. These bypass tracts give rise to antidromic atrioventricular (AV) re-entrant tachycardias, in which the bypass tract serves as the anterograde limb of the circuit and the AV node as the retrograde limb of the reentrant circuit. Since the antidromic AV reentrant tachycardia over a Mahaim fibre has a typically left bundle braunch block (LBBB) morphology, it is easy to make a misdiagnosis of supraventricular tachycardia with functional LBBB or even of ventricular tachycardia particularly in the presence of negative concordance.

When a Pseudo-Infarct Electrocardiogram (ECG) Pattern in a Posterior Accessory (Wolff-Parkinson-White) Pathway Masks a True Inferior Infarct.

Am J Case Rep 2018 Jun 13;19:685-688. Epub 2018 Jun 13.

Gill Heart Institute and Division of Cardiovascular Medicine, University of Kentucky, Lexington, KY, USA.

BACKGROUND Wolff-Parkinson-White (WPW) pattern is due to a pre-excitation leading to characteristic ECG changes in sinus rhythm as short PR interval, the presence of delta waves, wide QRS complexes, and potentially Q wave-T wave vector discordance (pseudo-infarct pattern). These later changes can mask the underlying ECG depolarizing solely through the His-Purkinje system. Our case highlights how the ECG of a WPW pattern with a pseudo-infarct pattern can in fact mask a true infarct on the underlying ECG without pre-excitation. Read More
