BACKGROUND: Spinal and bulbar muscular atrophy (SBMA) is an X-linked recessive hereditary neuromuscular disorder caused by the expanded trinucleotide repeat in the androgen receptors gene. The major clinical manifestations of SBMA consist of weakness in the bulbar and limb muscles, fasciculations, tremors, cramps, sensory impairment, and gynecomastia. However, atypical SBMA cases may lead to misdiagnosis. Muscular fatigue and decremental responses to repetitive nerve stimulation (RNS), despite being observed in some SBMA patients, are usually occurred in MG patients, and patient with the symptom of mastication fatigue was rarely reported...

BACKGROUND: Dextrocardia is a congenital heart malformation with a low incidence that occurs in only 1 in 10,000-12,000 people. Wolff-Parkinson-White (WPW) syndrome is a congenital condition with additional accessory pathways between the atria and the ventricle, which affects up to three in 1,000 people worldwide. Experience of radiofrequency catheter ablation in patients with WPW syndrome and dextrocardia is scarce due to its rare incidence. CASE PRESENTATION: A 39-year-old female was hospitalized due to two episodes of palpitations in the latest 2 months...

BACKGROUND: Although cryoablation (CA) of septally located accessory pathways (APs) is an established treatment for Wolff-Parkinson-White Syndrome, its major limitation is the lack of data regarding long-term follow-up (FU). The present study sought to investigate long-term outcomes of a specific CA protocol targeting para-Hisian (P-H) and mid-septal (M-S) APs. METHODS: Twenty-six patients who previously underwent CA of PH or MS APs from 2004 to 2014, were prospectively considered to receive a FU during 2021...

Wolf-Parkinson-White syndrome (WPW) syndrome can mimic myocardial infarction (MI) due to the prominent repolarization changes secondary to abnormal myocardial activation by accessory pathway. Rarely these repolarization changes might mask the classical electrocardiographic (ECG) picture of MI and present with atypical ECG features, delaying the diagnosis in the emergency room. We present a case, where the onset of the MI in WPW syndrome was identified based on delta-T wave concordance, and QRS fragmentation...

BACKGROUND: Existing algorithms to predict the location of an accessory pathway (AP) in Wolff-Parkinson-White Syndrome (WPW) have good sensitivity and specificity but complex with various accuracy and inter-observer agreement rates. A simple algorithm with high accuracy and inter-observer agreement rates is needed. METHODS: This was a cross-sectional and retrospective diagnostic study. The data were collected by total population sampling from January 2015 to January 2017...

OBJECTIVES: Fasciculoventricular fiber (FVF) that does not cause tachyarrhythmia is a rare form of ventricular preexcitation, which is important to distinguish from Kent fibers. Although, adenosine and some electrocardiographic features are important in the differentiation of Wolff Parkinson White (WPW) than FVF, a clear distinction may not always be possible without an electrophysiological study (EPS). In this study, we aimed to present the clinical and electrophysiological features of our pediatric patients with fasciculoventricular fiber...

Background: Implantable cardioverter defibrillators (ICDs) are most effective in treating sudden cardiac death. However, accurate diagnostic workup of broad complex tachycardia is crucial to ensure correct indication for ICD treatment and to avoid unnecessary invasive treatment and device-associated morbidity. Case summary: We present a case of atypical atrial flutter with 2:1 atrioventricular (AV) conduction via a left-posterior accessory pathway (AP), leading to the diagnosis of Wolff-Parkinson-White (WPW) syndrome...

The success of radiofrequency catheter ablation of the accessory pathway (AP) depends on the accurate localisation of the bypass tract. In that respect, posteroseptal or inferior paraseptal APs often pose a diagnostic challenge because of the complex anatomy at the crux of the four cardiac chambers. Considering the differences in procedure risks and success rate depending on the need for a left-sided approach or a coronary sinus ablation, an accurate anticipation of the precise location of inferior paraseptal APs is critical to inform the consent process and guide the initial mapping strategy...

One-to-one atrioventricular conduction during atrial flutter is one of the most severe life-threatening arrhythmias and is hemodynamically perilous. Rapid wide QRS tachycardia often not only occurs in patients with ventricular tachycardia but is also found in supraventricular tachycardia/atrial flutter with preexistent QRS prolongation, supraventricular tachycardia/atrial flutter with QRS prolongation caused by an IC antiarrhythmic drug, and supraventricular tachycardia/atrial flutter with preexcitation. Furthermore, atrial flutter with 1:1 AVC via an accessory pathway is an uncommon presentation of Wolff-Parkinson-White syndrome...

AIMS: To define the prevalence of non-sustained tachyarrhythmias and bradyarrhythmias in patients with the m.3243A>G mitochondrial genotype and a previously defined, profile, associated with 'high sudden-death risk'. METHODS AND RESULTS: Patients at high risk of sudden death because of combinations of ventricular hypertrophy, mitochondrial encephalopathy, lactic acidosis and stroke-like episodes family phenotype, epilepsy or high mutation load, due to the m.3243A>G mutation, were identified from a mitochondrial cohort of 209 patients...

Congenital left ventricle to coronary sinus fistula is a rare entity. We report a case of an infant with prenatal finding of left ventricle to right atrial shunt. The anatomy was defined by multi-modality imaging. Baseline electrocardiogram was notable for a Wolff-Parkinson-White pattern. He underwent successful catheter device closure of the left ventricle to coronary sinus fistula. The patient developed supraventricular tachycardia and underwent successful ablation of the accessory pathway.

Wolff-Parkinson-White (WPW) syndrome is rare and is characterized by an accessory pathway that predisposes patients to tachyarrhythmias and sudden cardiac death. Early recognition is important and should be evaluated by a multidisciplinary team for adequate management and treatment. We present a pregnant woman that presented to the emergency department and discuss her diagnosis, treatment, and outcome.

BACKGROUND: Left ventricular noncompaction (LVNC) is a rare type of cardiomyopathy, and one of its clinical manifestations is arrhythmia. Cardiovascular magnetic resonance (CMR) is valuable for the diagnosis and prognosis of LVNC. However, studies are lacking on the use of CMR for LVNC patients with arrhythmia. This study aimed to characterize and compare CMR features and prognosis in LVNC patients with and without arrhythmia. METHODS: Eighty-four LVNC patients diagnosed by CMR were enrolled retrospectively in this study...

A 79-year-old Caucasian male was referred to cardiology clinic because the electrocardiogram showed premature atrial complexes and pre-excitation (delta waves) thought to be consistent with Wolff-Parkinson-White (WPW) syndrome. He did not report symptoms of palpitations or syncope. Careful analysis of the electrocardiogram revealed a fascicular-ventricular pathway (FVP) responsible for pre-excitation. Differentiating FVP from WPW syndrome is essential as the risk profile is different with each. Electrocardiographic observations that could help identify the presence of an FVP and its diagnostic, prognostic, and therapeutic implications are presented...

BACKGROUND: Danon disease is typically associated with cardiomyopathy and ventricular pre-excitation. The study aimed to characterize the clinical profile of Danon disease, analyze electrocardiographic (ECG) and electrophysiologic features, and investigate their association with Wolff-Parkinson-White (WPW) syndrome and fasciculoventricular pathways (FVPs).Methods and Results:Clinical course, family history, ECG and electrophysiological data were collected from 16 patients with Danon disease...

BACKGROUND: Atrial fibrillation in Wolff - Parkinson - White syndrome may result in life-threateningly rapid antegrade conduction over a bypass tract, manifested by an irregular broad-complex (pre-excited) tachycardia that can degenerate to ventricular fibrillation. The shortest pre-excited RR interval below 250 ms during atrial fibrillation (AF) predicts increased risk of sudden cardiac death. CASE SUMMARY: We report a case of a 43-year-old man with unremarkable cardiac history who presented due to sudden-onset feeling of palpitations and pre-syncope after strenuous lifting...

The aim of the study was to analyze the prevalence of asymptomatic VPP among young athletes when the screening protocol includes both resting and exercise ECG and determine the role of stress ESG testing in the detection of VPP among asymptomatic athletes. We conducted a cross-sectional retrospective study of 15.187 young Georgian athletes from 12 to 25 who underwent cardiac preparticipation screening at the TSMU Clinical Center of Sports Medicine and Rehabilitation from 2010 to 2019. From these 15187 subjects we analyzed rest and exercise ECGs of athletes referred to an electrophysiologist and identified 25 athletes among them with asymptomatic VPP...
