There is not yet agreement about the optimal size of the prostheses in aortic and mitral valve replacement with Manouguian's technique. In this technique, the aortic prosthetic valve can be pushed upon the mitral prosthesis which may cause dysfunction of the aortic prosthetic valve. The aim of this study was to clarify the size of the prostheses needed to(More)
BACKGROUND We performed a retrospective study of patients who underwent a video-assisted minimally invasive right mini-thoracotomy approach for cardiac benign tumor resection compared with median sternotomy. METHODS Of 23 patients who underwent isolated benign cardiac mass resection at the Japanese Red Cross Nagoya Daiichi Hospital from 2001 to 2014, 16(More)
Calpain is a Ca(2+)-activated neutral protease that supposedly plays a key role in myocardial dysfunction following ischemia/reperfusion, by degrading certain proteins involved in the contraction mechanism. It is possible that overexpression of calpastatin, an endogenous calpain inhibitor, lessens contractile dysfunction in the heart after reperfusion by(More)
72-year-old woman presented with the chief complaint of shortness of breath. Her medical history ncluded a diagnosis of tetralogy of Fallot with a right ortic arch and a status post–classical Blalock-Taussig hunt at 26 years of age in 1962. The cardiothoracic ratio as 84% on chest roentgenogram (Fig 1). The arteral oxygen saturation was 83%.(More)
OBJECTIVES We developed trans-right axillary aortic valve replacement (TAX-AVR) as a more cosmetically superior approach to minimally invasive AVR. We herein retrospectively compared the safety and invasiveness between TAX-AVR and conventional AVR (C-AVR). METHODS TAX-AVR was performed under femorofemoral cardiopulmonary bypass. Creation of a small right(More)
Postinfarction ventricular septal rupture is still a surgically challenging situation with high operative mortality. We report a case of ventricular septal rupture in a 75-year-old woman successfully treated with our newly devised technique, in which a pliable large septal path is fixed with transmural sutures placed in posterior left ventricular free wall(More)
This study evaluated the clinical advantage of a novel technique to reconstruct a true lumen with aortic wall tailoring for aortic repair (aortic tailoring) or the reimplantation of intercostal arteries (vascular tube) in a chronic type B aortic dissection. Thirty-three consecutive extended thoracoabdominal aortic repairs have been performed for chronic(More)
Bentall operation has been a gold-standard procedure for the aortic root reconstruction in the patients with aortic root aneurysms and aortic valve insufficiency (AI). Recently, native aortic valve preserving operation has been widely spread. In this study, we described the results of aortic root reconstruction in our institution and evaluated our operative(More)
OBJECTIVES Surgical results for post-infarction ventricular septal rupture (VSR) remain poor, even today. The aim of this study was the establishment and clinical evaluation of a simple, standardized septal patch technique for this disease. METHODS From 1999 to 2011, 16 consecutive patients with a mean age of 73.1 ± 10.1 (range 55-89) underwent emergency(More)
OBJECTIVES Totally endoscopic minimally invasive mitral valve surgery (MIMVS) is technically demanding and often performed with robotic assistance. We hypothesized that three-port video-assisted thoracic surgery (VATS) would facilitate endoscopic MIMVS and evaluated its feasibility and safety. METHODS From October 2010 to June 2016, we performed(More)
