Echocardiograms (echo) and vectorcardiograms (VCG) from 40 infants with ventricular septal defects (VSD) were compared with cardiac catheterization data to assess noninvasively the hemodynamics of VSD. The specific aim was to use VCG parameters of right ventricular hypertrophy and echo parameters which reflect pulmonary artery pressure to identify all patients with a nonrestrictive VSD. The con...

Acute ventricular septal rupture - ventricular septal defect (VSD) following acute myocardial infarction remains a critical condition. We present an 80 year-old patient with an acute VSD following an acute inferior myocardial infarction. Percutaneous VSD closure with an Amplatzer ventricular septal occluder (AVSO) was performed successfully, two days after initial admission. In-hospital follow-...

Affinity propagation (AP) was recently introduced as an unsupervised learning algorithm for exemplar based clustering. In this paper novel text document clustering algorithm has been developed based on vector space model, phrases and affinity propagation clustering algorithm. Proposed algorithm can be called Phrase affinity clustering (PAC). PAC first finds the phrase by ukkonen suffix tree con...

Optical imaging with voltage-sensitive dyes (VSD imaging) can record neural activity over an area of several square centimeters with high spatiotemporal resolution. The relative contributions of subthreshold and suprathreshold activity to the VSD signal are, however, poorly understood, making it difficult to interpret the imaging result. This paper shows how the activity in a computational mode...

BACKGROUND The ventricular septal defect (VSD) is the most common form of congenital heart defects. The purpose of this study was to evaluate the results of the early complications and mid-term follow-up of the transcatheter closure of the VSD using the Amplatzer VSD Occluder. METHODS Between April 2012 and October 2013, 110 patients underwent the percutaneous closure of the perimembranous VS...

Ventricular septal defect (VSD) is a lethal complication of myocardial infarction. The event occurs 2-8 days after an infarction and patients should undergo emergency surgical treatment. We report on successful device closure of post-infarction VSD. A previously healthy 66-year-old male was admitted with aggravated dyspnea. Echocardiography showed moderate left ventricular (LV) systolic dysfunc...

The use of nonbinary convolutional codes with Vector Symbol Decoding (VSD) was proposed to correct long burst errors in high data rate wireless networks. VSD allows the symbol size to easily and arbitrarily increase as desired. Therefore, the same technique can be used for both the current data rate and any upcoming data rate of new wireless network standards. Convolutional VSD is more attracti...

Two cases of PA-VSD were examined by computed tomography angiography (CTA) using dual-source 128-MDCT to reveal the anatomy and morphology of the pulmonary circulation. The first case was diagnosed as PA-VSD type B, while the second case was diagnosed as PA-VSD type A. These cases show that dual-source 128-MDCT can be used to provide clinical information for PA-VSD with the appropriate examinat...

Voltage-activated proteins can sense, and respond to, changes in the electric field pervading the cell membrane by virtue of a transmembrane helix bundle, the voltage-sensing domain (VSD). Canonical VSDs consist of four transmembrane helices (S1-S4) of which S4 is considered a principal component because it possesses charged residues immersed in the electric field. Membrane depolarization compe...

Transcatheter closure of perimembranous and muscular ventricular septal defect (VSD) has been performed widely and it has more advantages compare to surgery. However, transcatheter closure of residual VSD post operation of complex congenital heart disease is still challenging because of the complexity of anatomy and concern about device stability, so the operator should meticulously choose the ...
