We report a case of reoperation for proximal pseudoaneurysmal formation of the ascending aorta and distal enlargement of the dissecting arch and descending aorta after ascending aorta replacement for acute type A aortic dissection. The patient was a 47-year-old man who had undergone ascending aorta replacement and aortic valve replacement for acute type A aortic dissection three months previously. Pseudoaneurysm of the ascending aorta and enlargement of the dissecting arch and descending aorta were revealed by computed tomography. Therefore, we performed extensive replacement of the aortic root, arch and descending aorta. Median re-sternotomy with left anterolateral thoracotomy the (“Door open method”) was applied as the surgical approach. After reconstructing the aortic root using the modified Bentall procedure, we replaced the arch and descending aorta using antegrade continuous coronary perfusion with systemic blood through the composite graft of the aortic root under non-cardioplegic arrest. Despite the long duration of extracorporeal circulation, the duration of cardioplegic arrest was relatively short, and the postoperative cardiac function was not deteriorated at all. The patient is currently doing well with no problems at 1.5 years after the surgery. The Door open method was a useful approach providing good operative exposure in this case requiring extensive replacement of the thoracic aorta. Antegrade continuous blood coronary perfusion was useful for performing the arch and descending aortic replacement under non-cardioplegic arrest, and it was a reliable strategy for ensuring myocardial protection and avoiding prolonged duration of cardiac ischemia.

We present a rare case of cardiac surgery for coronary artery single vessel disease and aortic valve stenosis after substernal gastric interposition for gastric cancer. An 80-year-old man, who had undergone esophagectomy and substernal gastric interposition 7 years previously, was referred to our institute for surgical treatment of coronary artery disease and aortic valve stenosis. Through a median sternotomy with cardiopulmonary bypass, we performed aortic valve replacement and coronary artery bypass grafting to the right coronary artery without injury to the gastric tube. Postoperatively, the patient was on respirator care and catecholeamine support for several days. Although urinary tract infection occurred, he recovered with antibiotic therapy. Finally, he was discharged on postoperative day 40. For cardiac surgery after substernal gastric interposition for esophageal cancer, even though the substernal gastric tube may preclude the usual median approach, median sternotomy is an appropriate alternative with close preoperative examination and careful dissection of substernal gastric tube.

We describe two repeated operations to treat ascending aortic pseudoaneurysms. The first was emergency patch closure of the ascending aorta due to impending rupture 8 years after an operation for type I aortic dissection under hypothermic circulatory arrest. The second was endovascular repair using a fenestrated stent graft 7 years after coronary artery bypass grafting. No specific guidelines have been established regarding optimal management for such patients. We believe that individualized management is safer, especially for repeated operations.

A 74-year-old woman presented to our hospital with complaints of dysphagia. On examination, we diagnosed extensive thoracic aortic aneurysm and esophageal compression due to a descending thoracic aortic aneurysm. We planned a two-stage approach for repairing the extensive thoracic aortic aneurysm ; the first stage involving the repair of the ascending and arch segments, and the second stage involving the repair of the descending aorta. In the first stage, we performed the Bentall procedure and total arch replacement with a long elephant trunk. Following this, her dysphagia resolved, although the size of the descending aortic aneurysm was the same as that before the procedure (49 mm in diameter). We decided to treat her conservatively in the outpatient clinic without the second stage, because the descending aorta was asymptomatic and not sufficiently large. One year later, she presented with a sudden recurrence of dysphagia and swelling of buttocks. She was diagnosed with an expansion of the descending aortic aneurysm (62 mm in diameter) and a hematoma in the gluteal muscle due to aneurysm-induced disseminated intravascular coagulation (DIC). After emergency admission, she underwent a successful thoracic endovascular aortic repair and was discharged following a smooth recovery from dysphagia and aneurysm-induced DIC. We report this case along with a review of the literature.

An echocardiogram revealed a mobile mass attached to the left coronary cusp of the aortic valve in an 81-year-old woman. The tumor was surgically removed without valve replacement. The tumor was whitish in color, with a sea anemone-like appearance, and it measured 10 mm in maximum dimension. It was histopathologically defined as papillary fibroelastoma (PFE), and the postoperative course was uneventful. Primary cardiac tumors are rare, and the majority are myxomas. However recent advances in noninvasive examination and surgery may increase the detection of PFE, which occurs most frequently on the endocardial surface of the cardiac valve. We report a case of cardiac PFE with a review of the pertinent literature.
