A 45-year-old man was hospitalized with sudden-onset chest pain. He was in cardiogenic shock with a systolic pressure of 68 mmHg. His electrocardiogram (ECG) showed ST segment elevation in leads I, aVL, and V2-5. An emergency coronary angiogram (CAG) showed that the true lumens of bilateral coronary arteries were compressed, showing acute Stanford type A aortic dissection involving bilateral coronary artery. A bare metal stent was promptly implanted in the left main trunk (LMT) to restore coronary blood flow because of his hemodynamic instability. Soon afterwards, the ischemic changes on ECG disappeared and he was transferred to the operating room in a stable hemodynamic condition. We performed emergency graft replacement of the ascending aorta and coronary artery bypass grafting. The postoperative CAG showed patent bypass grafts. Implantation of LMT stent, as a bridge to surgery, should be the treatment of choice for acute type A dissection involving LMT.

OBJECTIVE: We conducted a retrospective, multi-institutional, collaborative study to accumulate cases of neuroendocrine carcinoma of the endometrium, to clarify its clinicopathologic features, treatment, prognosis and prognostic factors to collate findings to establish future individualized treatment regimens. To our knowledge, this is the largest case study and the first study to statistically analyze the prognosis of this disease. METHODS: At medical institutions participating in the Kansai Clinical Oncology Group/Intergroup, cases diagnosed at a central pathologic review as neuroendocrine carcinoma of the endometrium between 1995 and 2014 were enrolled. We retrospectively analyzed the clinicopathologic features, treatment, prognosis and prognostic factors of this disease. RESULTS: A total of 65 cases were registered from 18 medical institutions in Japan. Of these, 42 (64.6%) cases were diagnosed as neuroendocrine carcinoma of the endometrium based on the central pathological review and thus included in the study. Advanced International Federation of Gynecology and Obstetrics stages (stage III and IV) and pure type small cell neuroendocrine carcinoma cases had a significantly worse prognosis. Upon multivariate analysis, only histologic subtypes and surgery were significant prognostic factors. Pure type cases had a significantly worse prognosis compared to mixed type cases and complete surgery cases had a significantly better prognosis compared to cases with no or incomplete surgery. CONCLUSION: Our findings suggest that complete surgery improves the prognosis of neuroendocrine carcinoma of the endometrium. Even among cases with advanced disease stages, if complete surgery is expected to be achieved, clinicians should consider curative surgery to improve the prognosis of neuroendocrine carcinoma of the endometrium.

An 87-year-old man underwent a transcatheter aortic valve implantation (TAVI) for severe aortic stenosis. Approximately 8 months later, he was readmitted to our institution because of a cerebral infarction. Viridans Streptococcus was identified from the blood culture, and transesophageal echocardiography revealed a mobile mass on the leaflet. Prosthetic valve endocarditis (PVE) was diagnosed and we initially administered intravenous antibiotic therapy for 4 weeks, after which the patient underwent surgical aortic valve replacement. Herein, we report on the surgical AVR in the patient using a pericardial valve after successful removal of the infected prosthetic valve, and discuss some issues related to this rare complication after TAVI.

The patient was a 34-year-old woman who had been routinely monitored after receiving a childhood diagnosis of partial anomalous pulmonary venous connection, but unilaterally discontinued follow-up examinations after the age of 18. At 33 years of age, she was admitted to our hospital after a physical examination revealed an abnormal shadow on a chest X-ray. Transthoracic echocardiography detected an atrial septal defect (ASD), and contrast-enhanced computed tomography showed that the right lower pulmonary vein drained to the inferior vena cava. The patient was diagnosed with scimitar syndrome with ASD. Cardiac catheterization showed a pulmonary/systemic flow ratio (Qp/Qs) of 2.48 and a left-to-right shunt rate of 59.7%. Surgical treatment was deemed to be indicated. The right lower pulmonary vein was anastomosed to the anterolateral wall of the right atrium, and an intra-atrial baffle repair was performed from the orifice within the right atrium to the left atrium through the existing ASD using untreated fresh autologous pericardium. Two years after the operation, good blood flow was maintained within the baffle with no stenosis at the anastomotic site. This report describes a rare case of scimitar syndrome with ASD in an adult woman, and provides a review of the existing literature.

A 79-year-old woman presented to our hospital with high energy trauma. Enhanced CT revealed injury to the aortic arch. The left carotid artery was pulled out due to extension force and a drawing out lesion formed. Cardiopulmonary bypass was established with cannulation of the right femoral artery and the right atrium, and systemic cooling was started. We opened the aortic arch with deep hypothermic circulatory arrest, and detected a 10 mm drawing out lesion at the bottom of the left carotid artery. Aortic arch was transected at the distal of the left carotid artery to exclude the drawing out lesion, and partial arch replacement was performed. The patient's postoperative course was uneventful, and she was discharged from our hospital without any complication.

A 32-year-old woman was diagnosed with Takayasu's arteritis 5 years ago and underwent aortic valve replacement for aortic regurgitation 1 year ago. She had been taking Prednisolone and Azathioprine for Takayasu's arteritis, but these drugs were switched to subcutaneous Tocilizumab 4 months ago. One month ago, she had dyspnea on exertion, and 2 days ago, chest discomfort appeared, and she came to our hospital. Blood tests showed CRP 0.02 mg/dl, and echocardiography and CT showed perivalvular leakage and aortic root pseudoaneurysm, which led us to suspect aortic root pseudoaneurysm due to Takayasu's arteritis and to perform emergency surgery. Although a circumferential pseudoaneurysm was observed at the aortic root, no destruction of the prosthetic valve was observed. The suture from the previous surgery was attached to the sawing cuff of the prosthetic valve, and the prosthetic valve was not fixed to the aortic annulus and could be easily removed. The Bentall operation was performed using a bioprosthetic valve. The histopathological diagnosis was subacute infective endocarditis, and the patient was diagnosed with a pseudoaneurysm of the aortic root due to infection. The patient had a good postoperative course and was discharged home on the 19th day. We report a case of Takayasu's arteritis with valve annular abscess after AVR, which was treated surgically during biologic drug administration.

We report a case of a 56-year-old woman. She had a history of emergent ascending aorta replacement due to type A dissection. Seven years later, aortic arch enlargement (55 mm) was detected on CT scan, and indicated secondary repair. Because of the existence of the aberrant right subclavian artery (ARSA), the safer surgical management needed to be discussed. Total arch replacement with the use of open stent-grafting technique and extra-anatomical reconstruction of ARSA was chosen for the treatment. In the operation, straight woven grafts (7 mm in diameter) were firstly anastomosed to the bilateral axillary arteries. Deep hypothermic circulatory arrest with antegrade cerebral perfusion through median sternotomy was established. The aortic arch was transected between the right and left subclavian arteries. The left subclavian artery was ligated at its origin, and an aortic open stent graft was inserted distally. An aortic reconstruction was performed between the left common carotid artery and the left subclavian artery with a 4 branched J-graft. The left carotid artery was reconstructed anatomically, and the tube grafts anastomosed to the bilateral axillary arteries were reconstructed in an extra-anatomical fashion. On the 11th postoperative days, coil-embolization of the ARSA was performed to complete the treatment. The patient had an uneventful post-operative recovery. Total arch replacement using an open stent-grafting technique was a feasible treatment option for the aortic arch aneurysm with ARSA.

Blunt traumatic rupture of the heart carries a high mortality rate. Anatomical injuries have included the atrium, appendage and ventricle but injury to the left appendage has been reported very rarely. We present the case of a 71-year-old female who was a driver in a motor collision with major front-end damage where air bags were deployed. After being intubated and receiving pericardiocentesis for cardiac tamponade at an advanced critical care and emergency medical center, the patient was taken to our hospital and emergently to the operating room for exploration. There was brisk bleeding coming from a 2 cm laceration on the left atrial appendage. The injury was repaired using 4-0 polypropylene felt pledget-supported horizontal mattress sutures on the beating heart with the assistance of cardiopulmonary bypass. The present report describes this patient and our findings from a literature review.
