Ventricular septal defect (VSD) is a common congenital heart disease (CHD) in childhood, and its incidence about 20% of CHD. Surgical closure or repair safe with acceptable results. Transcatheter VSD offers excellent Coil system developed for transcatheter occlusion. Infective endocarditis (IE) post device implantation very rare; however, it possible. IE represents surgical challenge associated...

OBJECTIVE This study intends to summarize 5 years of intraoperative hybrid procedure (IHP) experience with neonates and young children having congenital heart disease (CHD). METHODS From March 2003 to March 2009, a total of 152 consecutive patients younger than 2 years old who had undergone IHP were enrolled. In the balloon plasty group (n = 72), transventricular pulmonary valvuloplasty, or t...

A 21 years albanian patient was referred with important residual left to right shunt. He was undergone 7 years before conventional surgical correction of a perimembranous ventricular septal defect (VSD). The patient underwent sternotomy and perventricular device closure of the residual employing a 16 mm multifenestrated atrial septal defect occlude, which was positioned through the anterior wal...

Traditional treatment of muscular ventricular septal defect (VSD) is surgical closure, but it carries considerable morbidity and mortality. The Amplatzer muscular VSD occluder (AGA Medical Corporation, Plymouth, MN, USA) was approved by the United States Food and Drug Administration in September 2007 and by the Taiwan Department of Health in September 2009. It is a self-expandable double-disc d...

Atomic Force Microscopy (AFM) has rapidly gained widespread utilization as an imaging device and micro/nano-manipulator during recent years. This thesis investigates the new concept of a dual stiffness scanning probe with respect to biological applications and determines the resulting requirements for the scanning of soft bio samples, such as lowpressure contact. On this basis, an in-plane AFM ...

This paper shows a preliminary experimental evaluation of a novel haptic aiding for Remotely Piloted Vehicles. The aerodynamically-inspired haptic feedback law was named Conventional Aircraft Artificial Feel, and was implemented as a variable stiffness spring. The experimental set-up comprises a fully nonlinear mathematical model of the aircraft, a visual display and a haptic device (a 3 DoF Om...

In this paper, the modeling and the control of a variable stiffness joint actuated by a couple of twisted string actuators in antagonistic configuration is reported. The twisted string actuation system is particularly suitable for very compact and light-weight robotic devices, like artificial hands and arms, and renders a very low apparent inertia at the load side, allowing the implementation o...

BACKGROUND To evaluate the long-term safety and efficacy of using perventricular device closure in treating selected patient with doubly committed sub-arterial ventricular septal defect (VSD) METHODS: During July 2007 and April 2011, 86 patients with doubly committed subarterial VSD who met the inclusion criteria were enrolled in this study. Perventricular closure was attempted using a unique d...
