Vacuum evaporation process with metal mask using LTPS (Low Temperature Poly Silicon TFT) backplane is well established OLED production process. However this technology is not applicable for large sized display like TV. Various technologies to break through this constraint have been proposed so far. In this paper pros and cons of these proposed technologies are discussed and new approach, micro silicon TFT with unique anneal technology and laser transfer OLED process, is presented.

Coronary endarterectomy can be an effective and ultimate surgical alternative for diffusely diseased coronary arteries.See Commentary on page XXX.

The long-term durability of SCR with proximal aortic reapproximation exactly at the STJ was acceptable with low rates of proximal aortic events. This technique can be the standard technique for aortic root reconstruction in AAD patients, except those with aortic root pathology.

A 58‐year‐old woman was referred to our hospital with progressively increasing breathlessness. She reported a history of bioprosthetic valve implantation for tricuspid valve replacement and direct closure of an atrial septal defect for Ebstein's anomaly, 31 years before presentation. Transthoracic echocardiography revealed prosthetic valve failure, an enlarged coronary sinus, and severe mitral regurgitation. Computed tomography revealed a giant coronary sinus with thrombosis and persistent left superior vena cava. She underwent successful mitral and tricuspid valve replacement; however, severe hemodynamic deterioration necessitated mechanical ventilatory support with extracorporeal membrane oxygenation.
