INTRODUCTION Mitral valve prolapse syndrome (MVP) is the most common valvular abnormalityin the young and is correlated with increased frequency of cardiac dysrhythmias and sudden death.The aim of this study was to compare frequency of "early repolarization" in electrocardiogram(ECG) between MVP patients and healthy adults. METHODS In this cross-sectional study, we compared ECG presentations ...

OBJECTIVE To explore the role of Major Vault Protein (MVP) in oral cavity squamous cell carcinoma patients. SUBJECTS AND METHODS 131 consecutive patients suffering from oral cavity squamous cell carcinoma were included in the study. In the whole series, the mean follow-up for survivors was 123.11 ± 40.36 months. Patients in tumour stages I and II were referred to surgery; patients in stage II...

Major Vault Protein (MVP), the main constituent of the vault ribonucleoprotein particle, is highly conserved in eukaryotic cells and upregulated in a variety of tumors. Vaults have been speculated to function as cargo transporters in several cell lines, yet no work to date has characterized the protein in neurons. Here we first describe the cellular and subcellular expression of MVP in primate ...

BACKGROUND Mitral valve thickness is used as a criterion to distinguish the classical from the non-classical form of mitral valve prolapse (MVP). Classical form of MVP has been associated with higher risk of mitral regurgitation (MR) and concomitant complications. We sought to determine the relation of mitral valve morphology and motion to mitral regurgitation severity in patients with MVP. M...

CARDIAC abnormalities are the rule in hereditary myopathy, and myotonic dystrophy (MD) is no exception. Conduction disturbances are most common, manifested by first degree atrioventricular block,intraventricular conductive defect, and by evidence of disease in the entire conductive system on His bundle electrogram. The association between mitral valve prolapse (MVP) and MD has been reported as ...

A 68-year-old man with sick sinus syndrome (SSS) was referred to our department for pacemaker implantation. After implantation of a pacemaker with rate-responsive dual chamber (DDDR) mode and minimized ventricular pacing (MVP) functions, paroxysmal atrial fibrillation (PAF) repeatedly developed. Pacemaker memory showed that the intrinsic atrioventricular (AV) (atrial pacing-ventricular sensing ...

The term dysautonomia is used when there is a derangement in the reflex mechanisms of the limbic system resulting in improper control of pulse and blood pressure and even syncope sometimes. Cervical myelopathy may be complicated by dysautonomia and may rarely cause syncope; however, prolonged coma as a result of autonomic dysfunction in traumatic cervical myelopathy has not been described in th...

The present study was designed to investigate the incidence of benign joint hypermobility syndrome (BJHMS) in mitral valve prolapse (MVP) and the correlation between the echocardiographic features of the mitral valve and elastic properties of the aortic wall and Beighton hypermobility score (BHS) in patients with MVP and BJHMS. Fourty-six patients with nonrheumatic, uncomplicated, and isolated ...

Mitral valve plasty (MVP) is preferred over mitral valve replacement (MVR) for mitral regurgitation in humans because of its favorable effect on quality of life. In small dogs, it is difficult to repair multiple lesions in both leaflets using MVP. Herein, we report a case of severe mitral regurgitation caused by multiple severe lesions in the posterior leaflet (PL) in a mixed Chihuahua. Initial...
