Figure 1: Preoperative computed tomography showed hourglass type of supravalvular aortic stenosis and aneurysmal changes of the innominate and the left subclavian artery. When she underwent ventricular septal defect repair at the age of 4 months, transverse aortotomy was made for evaluating a bicuspid aortic valve. Probably the transverse aortotomy was closed by a continuous suture, which, by d...

This paper presents a physical modelling sound synthesis environment for the production of valved brass instrument sounds. The governing equations of the system are solved using finite-difference time-domain (FDTD) methods and the environment is implemented in the C programming language. Users of the environment can create their own custom instruments and are able to control player parameters s...

Solid phosphorus is successfully incorporated into a molecular-beam epitaxy system by a valved-cracker for the growth of phosphorus-based materials. The operating parameters are established through beam flux and reflection high-energy electron diffraction measurements. InP and InGaP lattice matched to GaAs were grown and characterized by Hall measurements, photoluminescence, electroreflectance,...

AIM To report our initial experience with lens-sparing vitrectomy for stage 4 retinopathy of prematurity using the 27-gauge (G) system. METHODS This retrospective case series involved nine eyes of five babies with active stage 4 ROP, who underwent 27-G lens-sparing vitrectomy. Surgery was done using 27-G valved cannulas and sclerotomies were made 1.5 mm from the limbus. Bilateral sequential v...

We report a rare complication occurring in a 72 year old patient previously undergone surgical aortic root replacement with Cabrol technique for an aneurysm of the ascending aorta and aortic valve incompetence. Sixteen years later the patient presented progressive congestive heart failure and a left ventricle-to-right atrium shunt due to the distal detachment of the valved tubular graft at leve...
