[Posterior Mitral Leaflet Patch Augmentation with Autologous Pericardium in a Neurofibromatosis Typeâ… Patient:Report of a Case].

The patient was a 61-year-old man with neurofibromatosis typeâ… , who had several papules in a whole body. Medical history included atrial fibrillation and cerebral embolism. Transthoracic and transesophageal echocardiogram revealed severe mitral valve regurgitation and tricuspid valve regurgitation due to annular dilation with atrial enlargement, tethering of the posterior mitral leaflet, the anterior mitral leaflet prolapse with chordal rupture.

Internal thoracic artery patch repair of a saccular left main coronary artery aneurysm.

Background: A saccular aneurysm located at the bifurcation of the left main coronary artery (LMCA) is an extremely rare condition. A major cause of left main coronary aneurysm is atherosclerosis, and common complications include thrombosis, embolism, and rupture. Despite the serious nature of this condition, the ideal operative approach to LMCA aneurysm (LMCAA) has not been established.

Quantitative assessment of manual and robotic microcannulation for eye surgery using new eye model.

Background: Microcannulation, a surgical procedure for the eye that requires drug injection into a 60-90 µm retinal vein, is difficult to perform manually. Robotic assistance has been proposed; however, its effectiveness in comparison to manual operation has not been quantified.

Methods: An eye model has been developed to quantify the performance of manual and robotic microcannulation.

Brachiocephalic venous aneurysm with unusual clinical observations.

Thoracic venous aneurysm is an extremely rare condition. This report describes the case of a 70-year-old woman with a left brachiocephalic venous aneurysm that caused recurrent nerve paralysis. Contrast-enhanced computed tomography and venography revealed a venous aneurysm, 4 cm in size, located adjacent to the venous angle.

Outcome after concomitant unilateral embolization of the internal iliac artery and contralateral external-to-internal iliac artery bypass grafting during endovascular aneurysm repair.

Objective: Despite improvement of devices, endovascular aneurysm repair (EVAR) is still challenging in cases with associated aneurysmal involvement of the iliac arteries. This study examined the safety and efficacy of EVAR with concomitant unilateral embolization of the internal iliac artery (IIA) and contralateral external-to-internal iliac artery bypass grafting, with bilateral endograft limbs extended into the external iliac arteries (EIAs).

Methods: The study included 22 consecutive patients (mean age, 74 years) who underwent elective endovascular repair of aortoiliac or iliac aneurysms, with concomitant coil embolization of the unilateral IIA and contralateral EIA-to-IIA bypass in the same operative setting.

[Our methods and techniques of thoracic endovascular aneurysm repair].

Thoracic endovascular aneurysm repair (TEVAR) is acquiring an established role as treatment for thoracic aortic aneurysm. It may be no exaggeration that TEVAR is a standard procedure, especially for decending aortic aneurysm. Furthermore we consider that aortic debranching with TEVAR for aortic arch or thoracoabdominal aortic aneurysm is very useful, and we aggressively perform TEVAR for them.

Infarction exclusion technique with transmural sutures for postinfarction ventricular septal rupture.

We present a case of postinfarction ventricular septal rupture (VSR) who underwent successful repair using a modified infarction exclusion technique. In our procedure a heterologous pericardial patch is sutured to healthy endocardium in the free wall and septum all around the infarcted area. Interrupted circular mattress sutures were placed through the ventricular wall in such a way as to exclude the VSR and the infarcted muscle of the left ventricle.

Usefulness of one-stage coronary artery bypass grafting on the beating heart and abdominal aortic aneurysm repair.

Abdominal aortic aneurysm (AAA) is commonly associated with coronary artery disease (CAD). Simultaneous coronary artery bypass grafting (CABG) with cardiopulmonary bypass (CPB) under cardiac arrest and AAA repair may be considerably invasive. Recently CABG under the beating heart without CPB has been reported as a less invasive method.
