A 78-year-old female was referred to our hospital with a diagnosis of type A acute aortic dissection. There was a history of thrombosed aortic dissection six months prior and conservative management has been performed. Enhanced computed tomography showed type A acute aortic dissection with patent false lumen limited to the ascending aorta and ileus of the small intestine. Emergency hemiarch replacement was performed under mild hypothermic circulatory arrest and selective antegrade cerebral perfusion. Due to preoperative paralytic ileus, oral intake was initiated postoperative day four. Postoperative computed tomography revealed improvement of paralytic ileus. J. Med.

Whole-body periodic acceleration (WBPA) has been developed as a passive exercise device capable of improving endothelial function by applying pulsatile shear stress to vascular endothelium. We hypothesized that treatment with WBPA improves exercise capacity, myocardial ischemia, and left ventricular (LV) function because of increased coronary and peripheral vasodilatory reserves in patients with angina. Twenty-six patients with angina who were not indicated for percutaneous coronary intervention and/or coronary artery bypass grafting were randomly assigned to remain sedentary (sedentary group) or undergo 20 sessions of WBPA with the motion platform for 4 weeks (WBPA group) in addition to conventional medical treatment. WBPA was applied at 2 to 3 Hz and approximately ±2.2 m/s(2) for 45 minutes. We repeated the symptom-limited treadmill exercise test and adenosine sestamibi myocardial scintigraphy. In the WBPA group, the exercise time until 0.1-mV ST-segment depression increased by 53% (p
