Voltage-gated Na(+) (NaV) channels comprise a macromolecular complex whose components tailor channel function. Key components are the non-covalently bound β1 and β3 subunits that regulate channel gating, expression, and pharmacology. Here, we probe the molecular basis of this regulation by applying voltage clamp fluorometry to measure how the β subunits affect the conformational dynamics of the cardiac NaV channel (NaV1.5) voltage-sensing domains (VSDs). The pore-forming NaV1.5 α subunit contains four domains (DI-DIV), each with a VSD...

Technical selection for surgical repair of complete atrioventricular septal defect (CAVSD) still remains controversial. This meta-analysis aimed to compare the modified single-patch (MP) technique with the two-patch (TP) technique for patients with CAVSD. Relevant studies comparing the MP technique with the TP technique were identified through a literature search using MEDLINE, EMBASE, Google Scholar, Cochrane Library, and the China National Knowledge Infrastructure databases. The variables were ventricular septal defect (VSD) size, cardiopulmonary bypass (CBP) time, aortic cross-clamp (ACC) time, intensive care unit stay, hospital stay, and other outcomes involving mortality, left ventricular outflow tract obstruction, atrioventricular valve regurgitation, residual septal shunt, atrioventricular block, and reoperation...

Extracellular matrices (ECM) are commonly used to repair congenital heart defects; however, there is a lack of literature pertaining to outcomes with ECM use in high-pressure conditions. Between 2011 and 2014, a total of 202 patients underwent congenital heart disease repair using the ECM placed in a systemic pressure condition. The operative sites included: defects in the ventricular septum, mitral valve, aortic valve, ascending aorta, and aortic arch. Patients were followed and evaluated for mortality and reoperations due to loss of ECM integrity...

BACKGROUND: The nucleus basalis magnocellularis/Meynert (NBM) has been explored as a new target for deep brain stimulation for neurological disorders. Although anatomical studies suggest the existence of cholinergic topographical projections of the NBM, it is still unknown whether NBM subregions differentially activate the frontal cortex. OBJECTIVE: To investigate the topography between the NBM and frontal cortex. METHODS: Electrical stimulation was applied to the anterior and posterior sites of the NBM in rats, and the evoked frontal activity was investigated using voltage-sensitive dye (VSD) imaging...

Long term follow up studies have shown that transcatheter closure of perimembranous Ventricular Septal Defect (PmVSD) can be done safely and successfully. One of the most serious complications of VSD device closure is complete atrioventricular block which has been reported in 3-18% is various studies following VSD device closure. Amplatzar Duct Occluder II (ADO-II) device is now commonly being used for closure of small to moderate sized PmVSD. Complete heart block has not been reported with ADO-II device. We are reporting 2 cases of complete heart block following transcatheter closure of PmVSD using ADO-II device where sinus rhythm was established following early surgical removal of the device...

BACKGROUND: The 5, 10-methyleneterahydrofolate reductase (MTHFR) and methionine synthase reductase (MTRR) are two essential enzymes involved in folate metabolism. The relationship between genetic polymorphisms and congenital heart defects (CHDs) is inconsistent. Our aim was to investigate the association between two well-known polymorphisms of MTHFR and MTRR genes, C677T and A66G, respectively, and CHDs in Iranian patients. METHODS: We enrolled 74 patients with ventricular septal defect (VSD) and 79 with tetralogy of fallot (TOF) along with 147 healthy controls...

In depth-based 3D video, the view synthesis distortion (VSD) is generally measured by modeling the effect of texture and depth errors separately. With such a development, it has been referred that the VSD changes monotonically w.r.t. to both the texture and depth distortions. In this paper, we find the VSD not always change monotonically with them by both theoretical analysis and experimental test, when the effect of the texture and depth errors are considered together. Specifically, 1) we prove that the VSD is non-monotonic with the texture distortion...

Paravalvular leaks are common following valve replacement surgery. Majority are benign and do not require any active intervention. However, occasionally severe paravalvular regurgitation can produce heart failure and/or hemolysis, needing closure of the defect. It is more commonly associated with aortic and mitral prosthesis, symptomatic tricuspid paravalvular regurgitation being a rare entity. In this report we present the successful percutaneous transcatheter closure of a large paravalvular tricuspid regurgitation in a 59-year old lady with history of multiple previous operations...

BACKGROUND: Vector flow mapping is a novel echocardiographic flow visualization method, and it has enabled us to quantitatively evaluate the energy loss in the left ventricle (intraventricular energy loss). Although intraventricular energy loss is assumed to be a part of left ventricular workload itself, it is unclear what this parameter actually represents. The aim of the present study was to elucidate the characteristics of intraventricular energy loss. METHODS: We enrolled 26 consecutive children with ventricular septal defect (VSD)...
