Perioperative management of patients with pre-excitation syndromes.

Rom J Anaesth Intensive Care 2018 Oct;25(2):131-147

Department of Anaesthesiology, 401 Military Hospital, Athens, Greece.

Patients with pre-excitation abnormalities are at a high risk for life-threatening perioperative arrhythmias. In Wolff-Parkinson-White syndrome, the anaesthetics used for invasive diagnostic testing/ablation, should not affect cardiac electrophysiology; propofol, sevoflurane, fentanyl, sufentanil, alfentanil are suitable. In non-ablative surgery, propofol, sevoflurane, isoflurane, fentanyl, alfentanil, sufentanil have been used safely. Read More

A Case of Lown-Ganong-Levine Syndrome: Due to an Accessory Pathway of James Fibers or Enhanced Atrioventricular Nodal Conduction (EAVNC)?

Am J Case Rep 2018 Mar 18;19:309-313. Epub 2018 Mar 18.

Heart Institute, Joe DiMaggio Children's Hospital, Hollywood, FL, USA.

BACKGROUND Lown-Ganong-Levine syndrome, includes a short PR interval, normal QRS complex, and paroxysmal tachycardia. The pathophysiology of this syndrome includes an accessory pathway connecting the atria and the atrioventricular (AV) node (James fiber), or between the atria and the His bundle (Brechenmacher fiber). Similar features are seen in enhanced atrioventricular nodal conduction (EAVNC), with the underlying pathophysiology due to a fast pathway to the AV node, and with the diagnosis requiring specific electrophysiologic criteria.

A novel gain-of-function KCNJ2 mutation associated with short-QT syndrome impairs inward rectification of Kir2.1 currents.

Cardiovasc Res 2012 Mar 8;93(4):666-73. Epub 2011 Dec 8.

Department of Cardiovascular Medicine, Kyoto University Graduate School of Medicine, 54 Shogoin Kawahara-cho, Sakyo-ku, Kyoto 606-8507, Japan.

Aims: Short-QT syndrome (SQTS) is a recently recognized disorder associated with atrial fibrillation (AF) and sudden death due to ventricular arrhythmias. Mutations in several ion channel genes have been linked to SQTS; however, the mechanism remains unclear. This study describes a novel heterozygous gain-of-function mutation in the inward rectifier potassium channel gene, KCNJ2, identified in SQTS. Read More

Ablation therapy of supraventricular tachycardia in elderly persons.

Am J Geriatr Cardiol 2005 Jan-Feb;14(1):20-5

Department of Cardiovascular Disease, Florida Hospital, Orlando, FL,USA.

Ablation of supraventricular tachycardia in elderly persons presents a challenging problem to electrophysiologists. Friable cardiac structures, prone to catheter perforation, comorbid cardiovascular disease, and the propensity to develop atrial fibrillation and thromboembolic complications, place these patients at high risk. Newer techniques for cardiac mapping and ablation, the establishment of precise ablation lines, and safer approaches to the ablation mechanism (particularly for atrial fibrillation) are presented in this review.

[Ventricular pre-excitation: electrophysiopathology, criteria for interpretation and clinical diagnosis. References for geriatrics].

Minerva Cardioangiol 2001 Feb;49(1):47-73

Istituto di Clinica Medica Generale e Terapia Medica, Università degli Studi, Trieste, Italy.

The authors review the state-of-the-art on ventricular pre-excitation in medical and arrhythmological literature in order to facilitate the recognition of the various clinical forms, like classic and occult Wolff Parkinson withe syndrome and Lown Ganong Levine syndrome. A historical introduction reviews our electrophysiopathological knowledge of the electrical activation and conduction of ventricular pre-excitation compared to normal, starting from the anatomic discovery of conduction pathways to the possible use of transesophageal electrostimulation and endocavity mapping to study electric potentials. Avantgarde technologies have also been developed to eliminate anomalous pathways firstly by using a direct current dirscharge and secondly radiofrequency. Read More

Ventricular preexcitation in children and young adults: atrial myocarditis as a possible trigger of sudden death.

Circulation 2001 Jan;103(2):269-75

Department of Pathology, University of Padua Medical School, Padua, Italy.

Background: Sudden death (SD) in ventricular preexcitation (VP) syndrome is believed to be the result of atrial fibrillation with rapid ventricular response over the accessory pathway. Previous reports are anecdotal and often lack autopsy validation.

Methods And Results: Prevalence and clinicopathological features of VP were investigated in a series of 273 SDs in children and young adults (aged Read More

High incidence of pre-excitation syndrome in Japanese families with Leber's hereditary optic neuropathy.

Clin Genet 1996 Dec;50(6):535-7

Department of Ophthalmology, Keio University School of Medicine, Tokyo, Japan.

Cardiac conduction abnormalities have been reported in families with Leber's hereditary optic neuropathy (LHON). The pre-excitation syndrome Wolff-Parkinson-White syndrome or Lown-Ganong-Levine syndrome, is reportedly common in Finns with LHON, being seen in 14 (9%) of the 163 individuals with mitochondrial DNA (mtDNA) mutations. While this syndrome is thought to be rare in other ethnic groups with LHON, the present study of 35 Japanese LHON families confirmed that it is also relatively common among Japanese families, being seen in 5 (8%) of the 63 individuals with mtDNA mutations.

Clinical and evolutive aspects in ventricular preexcitation syndromes in child.

Rev Med Chir Soc Med Nat Iasi 1996 Jul-Dec;100(3-4):95-8

1st Clinic of Pediatrics, University of Medicine and Pharmacy, Iaşi.

Ventricular preexcitation syndromes (VPS) are very important between cardiac rhythm disturbances in childhood, because their presence can change the clinical and ECG picture and thus the treatment can be very difficult. The authors studied 58 cases of VPS in children (2 weeks-15 years old) admitted in a period of 3 years. The surface ECG showed VPS aspects: in 30% of cases we noticed WPW syndrome type B and the rest presented VPS with Mahaim pathways and Lown-Ganong-Levine syndrome. Read More

Medicina (B Aires) 1995 ;55(1):33-8

División Cardiología, Hospital Municipal Dr. Cosme Argerich, Buenos Aires, Argentina.

Unlabelled: The aim of this study was to assess use-dependence in patients with ventricular premature contractions (VPC's) treated with propafenone, by means of the increase in heart rate using transesophageal atrial pacing. It was also analyzed whether this phenomenon was related to the antiarrhythmic effect. Fifteen patients with more than 30 symptomatic VPC's/sour were evaluated. Read More

Enhanced A-V nodal conduction (Lown-Ganong-Levine syndrome) by congenitally hypoplastic A-V node.

Eur Heart J 1992 Nov;13(11):1579-84

Department of Cardiology, City Hospital, Vicenza, Italy.

The basic anatomical substrate of enhanced A-V nodal conduction, manifesting or not as Lown-Ganong-Levine syndrome, is still a controversial issue. We describe the case of a 34-year-old man who presented episodes of ventricular fibrillation. Electrophysiological studies showed that the AH interval was 55 ms, and increased by only 20 ms at paced cycle lengths of 300 ms; atrial pacing induced atrial fibrillation, with a shortest RR interval of 240 ms.

[Disorders of cardiac rhythm in combined ventricular pre-excitation syndrome and primary mitral valve prolapse].

Ter Arkh 1990 ;62(4):38-43

Primary prolapse of the mitral valve was diagnosed in 27 (11.7%) out of 230 patients with preexcitation syndrome: 10 of them presented with Wolff-Parkinson-White syndrome, 15 with Clerc-Lévy-Critesco syndrome, and two patients with combination of both syndromes. Preexcitation syndrome combined with mitral valve prolapse manifested itself by different disorders of the cardiac rhythm, mainly by the supraventricular forms: by PST in 17, nonparoxysmal tachycardia in 1, atrial fibrillation paroxysms in 7, sinus tachycardia in 2, supraventricular extrasystole in 3, pacemaker migration in the atria in 1 patient.

Ter Arkh 1990 ;62(10):84-8

Medico-genetic studies including preparation of the family pedigree, interviews, examinations, electro- and echocardiography were carried out in the families of 75 patients with pre-excitation syndrome (PES). Of these, 35 patients presented with Wolff-Parkinson-White (WPW) syndrome and 40 with Clerc-Lévy-Cristesco (CLC) syndrome. The studies made in possible to define the autosomal-dominant type of the syndrome or PES inheritance and to diagnose for the first time WPW syndrome in 3, PES in 1, CLC syndrome in 32 and CLC phenomenon in 89 persons out of 233 relatives of the first and second degree kinship.
