A 34-year-old woman was admitted with a history of syncope and a mass was detected in the right atrium (RA) by transthoracic echocardiography (TTE). Preoperative chest computed tomography (CT) also demonstrated an RA tumor measuring 4×3 cm. We performed resection of the RA tumor under cardiopulmonary bypass. Histopathological findings showed that the tumor was an angiomyolipoma. It is well known that angiomyolipomas are most frequently found in the kidney and are associated with tuberous scleroses. There was no evidence of tuberous sclerosis in this case. Primary tumors of the heart are rare. However, there have been a few intracardiac angiomyolipomas reported previously.

Objective : The aim of this study is to describe a series of patients undergoing reoperation due to hemolytic anemia after mitral valve surgery and assess the mechanisms and surgical outcomes. Methods : Between 2009 and 2014, we performed redo mitral valve surgery in 11 patients who had refractory hemolytic anemia after mitral valve surgery at Kyoto University Hospital. The mean age of the patients was 72.2±6.8 years old, and there were 5 men. Results : Preoperative echocardiography demonstrated that only 3 patients had ≥ grade 3 mitral regurgitation (MR), the rest of the patients had only mild to moderate MR. The mechanisms of severe hemolysis included paravalvular leakage (PVL) after mitral valve replacement (MVR) in 8 patients, structural valve deterioration (SVD) after MVR using a bioprosthesis in one, and residual/recurrent mitral regurgitation after mitral valve plasty (MVP) in two. All the patients except one (re-MVP) underwent MVR. The mean interval between previous operation and current operation was 14.1±9.4 years in post-MVR cases, and 2.0±1.9 years in post-MVP cases. There were three late deaths, one of which was due to cardiac death (exacerbation of heart failure due to pneumonia). There was one patient who required re-MVR for recurrent hemolysis due to PVL after MVR. Conclusion : Although hemolytic anemia after mitral valve surgery is rare, it often requires reoperation regardless of the degree of MR at late follow-up period. Thus, patients after mitral valve surgery should be carefully followed-up.

A 58-year-old man who complained of dyspnea on effort was given a diagnosis of decompensated congestive heart failure. Echocardiography revealed severe aortic regurgitation and cardiomegaly. We decided to perform aortic valve replacement with a mechanical valve, however his past history made us suspicious of allergy to metal. From his previous patient records, we determined he was allergic to many metals : gold, iron, platinum, cobalt, chrome, bronze, and zinc. Newly performed skin patch tests showed positive reactions to aluminum, tin, palladium, indium, iridium and stainless steel. We selected a CarboMedics mechanical valve made of nickel-titanium alloy. Aortic valve replacement with a 27-mm CarboMedics mechanical valve was performed by median sternotomy. At sternum closure, we used polyester non-absorbable suture thread, instead of surgical steel wire, because it contains stainless steel. His postoperative progress was good and he was discharged on the 10th postoperative day. One year after surgery he is doing well without any allergic symptoms.

Background: Gingyo-gedoku-san (GGGS) is an herbal medicine approved for upper respiratory infections in Japan. We conducted an open-label, multi-center, prospective trial, comparing GGGS with oseltamivir in patients with influenza and influenza-like illness (ILI) as a pilot study.
Methods: Subjects were healthy persons aged between 16 and 40, and were enrolled from January 12, 2010 to March 24, 2011. Fifteen patients were enrolled in this trial (8 and 7 for GGGS and oseltamivir, respectively). RT-PCR was positive for pandemic influenza A (H1N1) in 10 patients. The patients were provided with either GGGS or oseltamivir for 5 days. The primary outcome was mortality and/or hospitalization 7 days after the initial diagnosis. Body temperature and other clinical characteristics were also evaluated.
Results: All patients recovered from illness without complication or hospitalization. The mean time to resolve symptoms for the GGGS and oseltamivir groups was 3.9 days and 3.3 days, respectively (p=0.43). The GGGS group appeared to have a smaller symptom score AUC than the oseltamivir group, (p=0.26). Time to recover activity level appeared to be shorter in the GGGS group (p=0.10), with shorter time to recover health status (p=0.02). Sub-group analysis on patients with positive PCR showed similar results between the two groups.
Conclusion: GGGS was associated with symptom improvements resembling oseltamivir for both influenza and ILI. Randomized controlled trials involving larger sample sizes are needed to confirm these results.

The prevalence of migraine is higher in patients with atrial septal defect (ASD) (24.2%) than in the general Japanese population (9.4%). A few studies have reported that transcatheter closure of an interatrial shunt is known to attenuate migraine. We experienced hat surgical closure of the ASD improved migraine that was refractory to medication therapy. A 46-year-old man presented to a neurologist for evaluation of severe headache and was diagnosed with migraine. Brain magnetic resonance imaging (MRI) revealed evidence of previous multiple cerebral infarctions. Transesophageal echocardiography detected inferior sinus venosus-type ASD, and a bubble study showed the presence of a right-to-left shunt. Owing to the high index of clinical suspicion for paradoxical embolism via the ASD and the fact that percutaneous catheter closure was contraindicated for inferior sinus venosus-type ASD, we performed surgical closure of the ASD in this patient. The patient's migraine symptoms disappeared immediately after surgery, and no recurrence has been observed eight months after surgery. This is the first case report that surgical closure of ASD led to attenuate migraine. Our study highlights the association between right-to-left shunts and migraine, as well as the usefulness of the surgical closure of ASD as a therapeutic strategy for patients with migraine.

Knitted Polyester prosthetic grafts can cause long-term dilatations and formation of anastomotic or non-anastomotic aneurysms, and rupture in result. We experienced a case of anastomotic pseudoaneurysm and recurrent non-anastomotic dilatation of the ascending aorta-abdominal aorta bypass by Cooley Double Velour Knitted Dacron (CDVKD) graft for a patient with atypical coarctation of the aorta (Takayasu Aortitis, type III), which case needed treatment two times over 30 years after the initial operation. The first additional treatment was Thoracic Endovascular Aortic Repair (TEVAR) for non-anastomotic aneurysm was done as 1st operation. Thirty-two years after the initial operation, the second treatment was a hybrid operation consisting of 4 procedures: bilateral axillo-external iliac bypass, taking down of the CDVKD graft at the proximal anastomotic site, endovascular repair (EVAR) with modified Double D Technique, and coil packing at the distal anastomotic site of the CDVKD graft. The patient was discharged at 37-POD. No complication and no endoleak has occurred in the 2.5 years since the operation.

Among the less reported complications after thoracic endovascular aortic repair (TEVAR) is type II endoleak (T2EL). The intercostal and bronchial artery are known as feeder vessels to T2EL after TEVAR. We experienced two cases of successful treatment of percutaneous transarterial feeder vessels embolization via right costocervical trunk approach for patients with persistent T2EL and sac enlargement of an arch aneurysm after TEVAR. The costocervical trunk route is possible for key vessels to construct a collateral pathway to feeder vessels of the endoleak nidus of T2EL after TEVAR procedures for aortic arch aneurysm. A preembolizational Catheter-Directed CT angiogram (CTA) can be helpful to prevent harmful complications (e.g., spinal cord infarction).
