[Endocardial Blood Cyst in the Right Atrium:Report of a Case].

A 74-years-old man visited our hospital complaining chest discomfort, and he was diagnosed with variant angina. However, during close examination, a tumor with some small calcified nodules was accidentally pointed out in the right atrium. We carried out surgical removal to prevent embolism.

[Pacemaker Dislocation into the Peritoneal Cavity].

A 16-day-old neonate with congenital complete atrioventricular block underwent epicardial pacemaker implantation under the rectus. Four months later, abodominal X-ray imaging revealed dislocation of the generator from the abdomen to the pelvis. The infant was diagnosed with intraperitoneal pacemaker dislocation.

[Traumatic Disruption of the Aortic Root and the Ascending Aorta with Multisystem Trauma;Report of a Case].

We report a case of traumatic disruption of the aortic root with multisystem trauma. A 45-year-old male was suffered from multiple injuries including subarachnoid hemorrhage, lung contusion, retroperitoneal hematoma and femoral bone fracture caused by a traffic accident. He had a history of 3 cardiac surgeries including repair of atrioventricular septal defect and mitral valve replacement using a mechanical valve.

Superior Mesenteric Artery-Pancreaticoduodenal Arcade Bypass Grafting for Repair of Inferior Pancreaticoduodenal Artery Aneurysm with Celiac Axis Occlusion.

We report a case of an aneurysm of the inferior pancreaticoduodenal artery (IPDA), with chronic occlusion of the celiac axis. Both surgical aneurysmectomy and endovascular coil embolization were anticipated to sacrifice IPDA, which could lead to severe acute ischemia in the celiac region. The treatment involved surgical ligation of the aneurysm after bypass grafting from the superior mesenteric artery to the anterior IPDA.

[Early and Long Term Outcomes of Surgery for Acute Type A Aortic Dissection Complicated with Organ Malperfusion].

Objective: The purpose of this study was to evaluate early and long term outcomes of surgery for acute type A aortic dissection complicated with organ malperfusion.

Method: From January 2001 to October 2015, 336 consecutive patients (mean age 68.6±12.

Clinical Experience with the Nikkiso Centrifugal Pump.

The Nikkiso HPM-15 is a minimally sized centrifugal pump. Preliminary results regarding clinical use of this pump for cardiopulmonary bypass (CPB) procedures have been reported previously. Recently, we have managed some additional cases using a newly developed controller.
