Case ReportsA single-stage operation for bicuspid aortic valve, annulo-aortic ectasia, hypoplastic aortic arch, and coarctation of the aorta: A case report.
The patient was an 18-year-old man who had been diagnosed as having a bicuspid aortic valve and dilatation of the ascending aorta six years previously. As he grew up, aneurysmal change of the ascending aorta and hypertension in the upper body gradually progressed. Preoperative evaluation showed annulo-aortic ectasia and the following congenital abnormalities: bicuspid aortic valve, hypoplastic aortic arch, and coarctation of the aorta. Composite graft replacement and extended total aortic arch replacement were carried out.

Case ReportsMinimally invasive port-access coronary artery bypass grafting.
The Port-Access endovascular cardiopulmonary bypass system (Heartport, Inc., Redwood City, CA, USA), a recent technological innovation in minimally invasive cardiac surgery, was conducted successfully in coronary artery bypass grafting on a 69-year-old woman. The left internal thoracic artery was harvested through a limited left anterior thoracotomy and anastomosed to the left anterior descending coronary artery on a protected and arrested heart. ⋯ The patient was discharged from the hospital in good condition 7 days after the operation. This was the first successful minimally invasive Port-Access coronary artery bypass grafting in Japan.

Case ReportsBlunt traumatic rupture of the heart: case report and selected review.
Cardiac rupture is a common complication following blunt thoracic trauma. Blunt traumatic rupture of the heart is a frequent cause of death. ⋯ Rapid evaluation and expeditious management may increase the number of survivors. We present here an illustrative case report and selected review of literature regarding clinical presentation, mechanism of injury, investigation and treatment.

Surgical management of blunt traumatic rupture of the descending thoracic aorta.
Acute rupture of the descending thoracic aorta following blunt trauma is a life-threatening injury that requires emergent operative intervention. From February 1989 to January 1997, 4 patients with multiple injuries including traumatic rupture in the region of the aortic isthmus were surgically treated at our institution. Diagnosis was confirmed in all patients by aortogram prior to aortic repair. ⋯ The site of rupture was resected and replaced with an interposition artificial graft. There was no perioperative mortality and no additional occurrence of paraplegia. Our experience and a review of the literature indicate that for survivors of traumatic aortic rupture, excellent outcomes can be achieved only if the diagnosis is made early and the surgical treatment is prompt.

Clinical TrialPost-operative effects of olprinone after coronary artery bypass grafting.
The aim of this study was to test the effects of olprinone after coronary artery bypass grafting (CABG). In order to prevent hypotension caused by olprinone, low doses of catecolamines were used concomitantly. Total 22 elective CABG cases were evaluated. ⋯ There were no significant differences in urine output, oxygen delivery (DO2) and oxygen consumption (VO2) between both groups. Olprinone increased CI and decreased SVRI, and it showed easy weaning from CPB, demonstrating excellent hemodynamics after CABG. These results suggested that this new phosphodiesterase inhibitor may be effective for not only weaning from CPB but also post-cardiotomy cardiogenic shock.
