PURPOSE: Although useful for visualizing blood flow during revascularization surgery, the permeability of near-infrared fluorescence (NIR) angiography using indocyanine green (ICG) does not allow for vessel stenosis visualization. We hypothesized that changes in ICG fluorescence intensity reflect vessel stenosis, and evaluated the influence of stenosis on blood flow by ex vivo experimentation. METHODS: The vessel stenosis model comprised a silicon tube, a graft occluder, and artificial blood...

Heavy mitral annular calcification or severe destruction of the mitral annulus in the setting of mitral valve replacement may result in fatal complications, such as atrioventricular disruption, ventricular rupture, valve dehiscence, and perivalvular leakage. Collar-reinforced mitral valve replacements with xenopericardium have been reported to prevent perivalvular leakage and valve detachment. We herein describe our experience with an easy method of handling the modified collar-reinforced prosthetic valve, which we call the "Dumpling technique", in six patients...

#15
Yuichiro Ueda, Tatsuo Nakagawa, Toshiya Toyazaki, Naohisa Chiba, Masashi Gotoh
Rib resection for chest wall tumors, including lung cancer with chest wall invasion, is usually performed through open thoracotomy. Resection of part of the external rib cage requires an elongated or additional incision depending on the location and extension of the tumor, eventually becoming more invasive to patients. We recently introduced a technique of rib resection using a pneumatic high-speed power drill system known as "air tome". This novel technique is easy to perform through a small incision or even via video-assisted thoracoscopic surgery (VATS) in selected patients...
