Giant sinus node artery aneurysms with a fistula into the left atrium are extremely rare. A 76-year old woman was admitted to our hospital for an abnormality on her chest X-ray. Coronary computed tomography (CT) angiogram revealed a giant coronary aneurysm with feeding arteries arising from the sinus node artery and the left circumflex artery. Additionally,(More)
Left ventricular pseudoaneurysm (LVPA) is a known serious complication of myocardial infarction or mitral valve replacement. As an alternative option, transmitral patch repair for LVPA has been reported. However, it is very difficult to complete the procedure for LVPA with a large defect. A 68-year old man with a history of inferior myocardial infarction(More)
BACKGROUND Coronary perforation (CP) is a rare, but sometimes lethal, complication of percutaneous catheter intervention (PCI). We reviewed surgically-treated cases of type 3 CP during PCI. METHODS AND RESULTS From 2007 to 2010, 5 patients underwent surgical repair for type 3 CP (3 men, 2 women; mean age, 74 years). The mean number of diseased coronary(More)
BACKGROUND We previously reported effectiveness of coil embolization (CE) to aortic branched vessels before endovascular aortic repair (EVAR) for abdominal aortic aneurysm (AAA) because of significant shrinkage of aneurysmal sac. In this study, we investigated EVAR cases to clarify influential factors of aneurysmal shrinkage and enlargement. METHODS 148(More)
OBJECTIVE The aim of this study was to evaluate the midterm clinical outcomes of various approaches, including hybrid procedures, to aortic arch pathologies. METHODS Of 305 consecutive patients who underwent aortic arch repair between 2005 and 2013, 244 underwent conventional open total aortic arch repair (CTAR) with antegrade cerebral perfusion under(More)
BACKGROUND Abdominal aneurysmal sac enlargement after endovascular aortic repair (EVAR) is a critical issue. However, the predictors have not yet been fully determined. Although unrecognized, intraluminal thrombus volume (ITV) is an important index. Therefore, we retrospectively evaluated the correlation among preoperative ITV, residual type II endoleak,(More)
OBJECTIVE Persistent Type 2 endoleaks (PT2) after endovascular aortic aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA) are associated with increased adverse outcomes, including aneurysmal sac enlargement and rupture. The aim of this study was to report early clinical outcomes of coil embolization (CE) to aortic branched vessels prior to EVAR and(More)
There exists a substantial body of work describing cardiac support devices to mechanically support the left ventricle (LV); however, these devices lack biological effects. To remedy this, we implemented a cell sheet engineering approach utilizing chondrocytes, which in their natural environment produce a relatively elastic extracellular matrix (ECM) for a(More)
BACKGROUND Conventional reoperative mitral valve surgery by median sternotomy has several difficulties. We performed mitral valve replacement (MVR) under ventricular fibrillation (VF) through right mini-thoracotomy with three-dimensional videoscope for avoiding the problems. METHODS Between 2006 and 2011, we performed 257 cases of MVR, in which 125 cases(More)
