Case Reports[Chordal cutting for the treatment of ischemic mitral regurgitation: two case reports].
The surgical treatment for ischemic mitral regurgitation remains controversal. Ring annuloplasty results in recurrent mitral regurgitation in some cases. Strut chordal cutting is a new surgical procedure in addition to ring annuloplasty for ischemic mitral regurgitation. ⋯ Mitral leaflet tethering caused by apical displacement of the papillary muscle was observed. Mitral valve repair was performed by ring annuloplasty and chordal cutting. Intraoperative echocardiography showed that chordal cutting improved the configuration of the anterior leaflet, resulting in good mitral valve coaptation without regurgitation.

Case Reports[Uremic pericarditis complicating cardiac tamponade: a case report].
A 29-year-old man developed diabetes mellitus in 1983 and diabetic nephropathy which gradually worsened from 1998. He was admitted to our hospital for initiation of peritoneal dialysis in May 2002. However, the efficiency of dialysis was not sufficient to improve elevated levels of blood urea nitrogen and serum creatinine. ⋯ After hemodialysis, the amount of pericardial effusion decreased, the gastro-intestinal symptoms disappeared, and the blood urea nitrogen and serum creatinine levels decreased. We speculated that the cause of cardiac tamponade was uremic pericarditis after ruling out infectious disease, collagen disease, malignant disease, and aortic dissection. Cardiac tamponade due to uremic pericarditis has become very rare since hemodialysis was developed.

[Aortic root replacement using an allograft for active infective endocarditis with periannular abscess: single center experience].
Results of aortic root replacement using an allograft for active infective endocarditis in the aortic position and periannular abscess were studied. ⋯ Aortic root replacement with an allograft yielded acceptable clinical results.

Case Reports[Coronary artery dissection after blunt chest trauma: subacute and chronic phase assessment by intravascular ultrasonography: a case report].
A 35-year-old man sustained a steering wheel injury in a motor vehicle accident. Initial electrocardiography showed ST-segment elevation. Coronary angiography revealed a dissection of the right coronary artery and perfusion delay in the left anterior descending artery. ⋯ Coronary stents were inserted from the aorto-ostial lesion to the mid portion of the right coronary artery. Six months later, coronary angiography and intravascular ultrasonography revealed diffuse neointimal hyperplasia inside all of the stents, and the aorto-ostial stent had severe stenosis with perfusion delay. Severe neointimal hyperplasia was found inside the stents used for repair of the coronary artery dissection.
