BACKGROUND: Neonates with severe forms of Ebstein anomaly present a surgical challenge, and the Starnes operation as single ventricle palliation is highly advocated. Cone reconstruction for tricuspid valvuloplasty (TVP) has become a widely accepted technique, although very few cases of TVP have been reported in neonates. This report describes a surgical strategy for neonatal Ebstein anomaly, with an aim toward biventricular repair. METHODS: Since 2007, 7 neonates or young infants with severe Ebstein anomalies have received TVP at the National Taiwan University Hospital, Taipei, Taiwan...

BACKGROUND: Endoscopic endonasal nasopharyngectomy(EEN) can be a promising option for select patients with recurrent nasopharyngeal carcinoma, but serious complications can occur in terms of parapharyngeal internal carotid artery (PPICA) injury. Several landmarks have been proposed for locating the PPICA. In this study, we investigated the spatial relationship between the tensor veli palatini (TVP) muscle and the PPICA in a cadaveric model. METHODS: Seven fresh cadaver heads were available for anatomic study...

The purpose of this study was to assess the degree of lower incisor inclination with respect to different reference planes. It was an observational, analytical, longitudinal, prospective study conducted on 100 lateral cephalograms which were corrected according to the photograph in natural head position in order to draw the true vertical plane (TVP). The incisor mandibular plane angle (IMPA) was compensated to eliminate the variation of the mandibular plane growth type with the formula "FMApx.- 25 (FMA) + IMPApx...

Increasing evidence suggests that a new birnavirus, named chicken proventricular necrosis virus (CPNV), is the aetiological agent of transmissible viral proventriculitis (TVP). The present work aimed to explore the possible presence of both TVP and CPNV in the UK. Forty-four chickens showing TVP-compatible gross lesions were classified into three groups based on the histological lesions: (i) TVP-affected chickens: lymphocytic infiltration and glandular necrosis (n = 15); (ii) lymphocytic proventriculitis (LP)-affected chickens: lymphocytic infiltration without necrosis (n = 18); and (iii) without proventriculitis (WP): no lymphocytic infiltration or necrosis (n = 11)...

PURPOSE: Placement of TVPs is a core EM procedure. Despite this, there is no specific outcome data on this procedure in the ED setting. This study examines the success of Emergency Physician (EP) attempted TVPs as well as their hospital courses and survivals. METHODS: The charts of patients undergoing TVP placement in the ED of an urban community hospital were prospectively collected by a department billing abstractor and then underwent a structured review. All patients had a TVP placed by a board eligible or board certified EP or by a PGY2 EM resident under the direct supervision of an attending EP...

BACKGROUND: Significant tricuspid valve regurgitation (TR) is considered a poor prognosis factor for patients with hypoplastic left heart syndrome (HLHS). Performing a tricuspid valve plasty (TVP) during Norwood Stage I palliation (S1P) has rarely been reported. We report mid-term results of performing TVP during Norwood S1P. METHODS AND RESULTS: Between December 2004 and July 2013, 48 patients with HLHS or variants underwent Norwood S1P and of them 11 (23%) with TR of a moderate degree or above underwent TVP...

OBJECTIVES: In patients with congenitally corrected transposition of the great arteries (ccTGA) or after atrial (Mustard or Senning) correction for transposition of the great arteries (acTGA), the right ventricle (RV) supports the systemic circulation. The tricuspid valve (TV) (systemic atrioventricular valve) is prone to regurgitation in these patients and this is associated with impending RV failure and decreased survival. This study evaluates mid-term functional improvements, echocardiographic findings and survival after TV surgery in this patient group...

OBJECTIVE: The transplant vasculopathy as a sign of chronic graft rejection affects both the epicardial and the intramyocardial arteries of the graft. This is at least partially mediated by NO synthases. The aim of this study was to assess possible protective effects of cyclosporine A (CsA), tacrolimus (FK506), and mycophenolate mofetil (MMF) on the expression of NO synthases in an experimental transplant rat model. AIMS: Heart transplantation was performed in 322 rats...

Narrowed vessel accesses produce blood flow changes, and induce flow instability and vessel wall vibration, resulting in blood pressure, flow velocity, and flow resistance increases. The vessel wall vibrates and propagates the low axial blood flow, as representing the resistance (R) to blood flow. The compliance is a blood pressure-blood volume relation, representing the systole and diastole capacity of the blood vessel. These dynamic behaviors increase blood flow resistances and reduce blood vessel compliances...

Some researchers contend that in adults the tensor tympani muscle (TT) connects with the tensor veli palatini muscle (TVP) by an intermediate tendon, in disagreement with the other researchers. To resolve this controversy, we examined serial sections of 50 human embryos and fetuses at 6-17 weeks of development. At 6 weeks, in the first pharyngeal arch, a mesenchymal connection was found first to divide a single anlage into the TT and TVP. At and after 7 weeks, the TT was connected continuously with the TVP by a definite tendinous tissue mediolaterally crossing the pharyngotympanic tube...

Venous needle dislodgement (VND) is a life-threatening complication during haemodialysis (HD) treatment. When VND occurs, it only takes a few minutes for blood loss in an adult patient. According to the ANNA (American Nephrology Nurses' Association) VND survey reports, VND is a concerning issue for the nephrology nurses/staff and patients. To ensure HD care and an effective treatment environment, this Letter proposes a combination of fractional order shape index ratio (SIR) and fuzzy colour relation analysis (CRA) to detect VND...
