A case of anomalous origin of the left coronary artery from the pulmonary artery in a patient with the origin of the coronary opposite to the aorta is reported. Between many surgical options we conclude to reestablish a double coronary system reconnecting the coronary through a conduit created with a pulmonary wall baffle and an autologous pericardial patch.

The strategy for the management of adult patients with congenital heart disease (CHD) often represents a challenge for cardiac surgeons and cardiologists due to complex anatomy, wide range of clinical presentations, and a high-risk profile. However, hybrid approach may represent an attractive solution. We report three cases of adult patients previously operated for CHD and recently treated with...

In order to establish an echocardiographic profile of patients with simple transposition after Mustard's operation, we examined the M-mode records of 10 patients who were found to be free of significant abnormalities at follow-up cardiac catheterization. When compared with established normals, right ventricular wall thicknesses and cavity dimensions were increased, while left ventricular wall t...

Superconducting niobium cavities are important components of linear accelerators. Buffered chemical polishing (bcp) on the inner surface of the cavity is a standard procedure to improve its performance. The quality of bcp, however, has not been optimized well in terms of the uniformity of surface smoothness. A finite element computational fluid dynamics (cfd) model was developed to simulate the...

This paper presents the viewing angle improvement of integral imaging (II) three-dimensional (3D) display system using horizontal and vertical multi-directional projections and elemental image (EI) rearranging method with pepper and salt noise reduction. Through this way, each elemental lens of micro lens array gathers horizontal and vertical multi-directional illuminations of multiple EI sets ...

A micro-channel heat exchanger reactor with different micro-baffle shapes has been studied numerically. Governing equations were solved base on the finite volume method with FLUENT software. In upper section, oxidation reaction of methanol was occurred and in lower section, steam reforming of methanol was done. Two sections were separated with solid part which played as heat exchanger and trans...

In marine storage and transportation, the sloshing of liquid oxygen disturbs thermodynamic equilibrium induces stress on tank walls. Numerous problems are associated with mechanism demand a detailed investigation. this study, numerical model is developed by coupling Eulerian framework algebraic interface area density (AIAD) method while considering interphase drag force to investigate thermal b...

A surface plasmonic waveguide made of metal–insulator–metal (MIM) capable generating triple Fano resonances is proposed and numerically investigated for multi-biological parameter sensing as well tunable slow light. The up a bus with silver baffle, square split-ring cavity center (SSRCSC), circular ring (CRCSC). Based on the resonances, human blood temperature plasma concentration are measured ...
