BACKGROUND We developed a total right ventricular (RV) exclusion procedure for the treatment of isolated congestive RV failure. The objective of the present study was to elucidate the effects of a complete removal of RV volume overload (RVVO) on the surgically created single left ventricle (LV). METHODS AND RESULTS Three adults (2 arrhythmogenic RV(More)
OBJECTIVE A lateral tunnel-total cavopulmonary connection (LT-TCPC) using a right atrial (RA) free wall is the first choice of treatment for patients with a small body weight in this institute. Whether the growth of the LT is appropriate or not according to the growth of the body remains controversial. In addition, the optimal initial diameter of an LT is(More)
Aortic root dilatation is rare in children, and is often secondary to Marfan syndrome (MFS). We experienced a case of a three-year-old boy (92 cm, 12 kg) with MFS presenting with progressive dilatation of aortic root. We electively performed a valve-sparing aortic root replacement using a 24-mm Gelweave Valsalva graft. Although the patient required a mitral(More)
A 33-year-old man presented with severe aortic insufficiency due to a prolapsed bicuspid aortic valve. The ventriculoaortic junction was dilated to 29 mm without root dilatation, and external ring annuloplasty was performed using a Gelweave (Terumo, Tokyo, Japan) graft to reduce the size to 22 mm. The leaflets were repaired by dividing and suturing a raphe(More)
A 70-year-old woman was admitted to our institution with acute myocardial infarction. Coronary angiography demonstrated total occlusion of the left anterior descending artery, which was successfully revascularized. Four days later, the patient suddenly went into shock. The subsequent emergency operation revealed a blowout rupture of the left ventricular(More)
