JOURNAL FREE ACCESSWe herein report a rare case of an inflammatory pseudotumor arising from the mitral valve. A 58-year-old man who was undergoing maintenance dialysis was referred to us due to the presence of a tumor mass attached to the mitral valve. It was asymptomatic and had been coincidentally found by echocardiography. The tumor mass was a sphere measuring about 1 cm in size, and it arose from the posterior mitral leaflet. A myxoma of the left atrium was suspected, and the tumor mass was resected along with part of the posterior leaflet by means of a right minithoracotomy (MICS). The tumor was postoperatively diagnosed to be an inflammatory pseudotumor based on the findings of a histopathological examination. During the follow-up period of 1 year and 2 months after surgery, there was no recurrence. An inflammatory pseudotumor is a tumorous lesion characterized by the infiltration of inflammatory cells and the growth of myofibroblasts. This tumor occurs most frequently in the lung, and the greatest number of intracardiac cases have been reported in small children. There are few reports of inflammatory pseudotumors occurring in adults, and only 4 cases originating in the mitral valve has so far been reported, which means that such tumors are extremely rare. For this reason, we reported the findings of this case, while adding a bibliographical survey.View full abstractDownload PDF (894K) -

JOURNAL FREE ACCESSA 67-year-old man who had undergone robot-assisted laparoscopic radical prostatectomy 16 days before suffered from high fever. A screening CT showed an aortic arch aneurysm was 40 mm in diameter, and Bacteroides fragilis was identified from blood culture. A few days after the first CT, the size of the aneurysm increased rapidly to 50 mm in diameter, subsequently an urgent procedure of total arch replacement using rifampicin-soaked Dacron graft was performed. Although the postoperative course was unremarkable, pyrexia recurred on the ninth post operative day. The third CT showed a new aneurysm in the thoraco-abdominal aorta just below the celiac artery. The second urgent procedure of graft replacement of the thoraco-abdominal aorta with the reconstruction of the celiac artery was performed. Preoperative FDG-PET/CT was useful to decide the level of the resection and the suture. The intravenous administration of the antibiotics continued for six weeks after surgery. The patient is doing well without any signs of infection on oral antibiotics at 7 months after the second surgery.View full abstractDownload PDF (536K) -

JOURNAL FREE ACCESSA 73-year-old man who underwent redo aortic valve replacement due to dysfunction of tissue heart valve developed hypoxemia with bilateral infiltrates on frontal chest radiograph and hypotension shortly after his operation. Due to the presence of progressive hypotension and hypoxemia, we inserted an intra-aortic balloon pump and, furthermore, provided percutaneous cardiopulmonary support. We ruled out cardiogenic pulmonary edema based on information from various examinations, including echocardiography, and subsequently diagnosed possible transfusion-related acute lung injury (possible TRALI). The patient was treated by mechanical ventilation and circulatory support under close supervision, showing a trend of improvement from postoperative day 2 and discontinuing mechanical ventilation on postoperative day 11. The patient made an uneventful recovery and was discharged on postoperative day 50. Cardiac surgery patients are at particular risk for TRALI, so physicians should consider TRALI whenever a patient develops hypoxemia during or shortly after transfusion. Rapid diagnosis and appropriate treatment of TRALI are especially important in cardiac surgery patients.View full abstractDownload PDF (495K) -

JOURNAL FREE ACCESSAn 83-year-old man was transferred to our hospital with cardiac tamponade and suspected cardiac tumor detected by enhanced CT. Coronary angiography showed a coronary aneurysm of 50 mm ID on the left circumflex artery. An emergency surgery was performed to excise the aneurysm, and a fresh thrombus occupying the efferent artery was observed. Both the afferent and efferent vessels were closed by suture. The patient made an otherwise uneventful recovery. This case featured a fresh red thrombus formed in fistulous outflow of the coronary aneurysm that seemed a direct cause of rupture.View full abstractDownload PDF (610K) -

JOURNAL FREE ACCESSWe report an extremely rare case of leiomyosarcoma originating from the abdominal aorta. The patient was a 57-year-old man who had palpable abdominal mass with pain. The symptoms were consistent, and urgent operation was done due to impending rupture of the abdominal aortic aneurysm. The intraoperative findings showed that the mass was a primary tumor of the abdominal aorta, and the histological diagnosis was leiomyosarcoma. It is reported that its prognosis is very poor, but he survived 7.5 years after diagnosis by reason of aggressive management including surgical treatment, chemotherapy and radiotherapy.View full abstractDownload PDF (1312K) -

JOURNAL FREE ACCESSThe method of cardioplegic myocardial protection is often controversial for re-cardiotomy after a coronary artery bypass grafting (CABG). A 69-year-old woman with a history of three previous surgeries consisting of closed mitral commissurotomy (CMC), dual valve replacement (DVR), and CABG underwent mitral valve replacement (MVR) and CABG for perivalvular leakage (PVL). As a result, the bilateral coronary ostium and the bypass graft to the right coronary artery (RCA) were totally occluded. The left internal thoracic artery (LITA) graft to the left anterior descending (LAD) coronary artery was the only inflow to the left coronary artery system and the right coronary artery system developed collateral inflow. Cardioplegia was carried out by performing a temporary anastomosis graft on the saphenous vein graft (SVG) in the left anterior descending coronary artery and a new bypass graft in the RCA was used for the administration of cardioplegic solution with no complications. There are various strategies for cardioplegic myocardial protection. The best method should be selected depending on the patient characteristics and condition.View full abstractDownload PDF (588K) -

JOURNAL FREE ACCESSThe optimal strategy for shaggy aorta syndrome has not been established, however, several case reports are published with the increase of the aged population. We report two men with shaggy aorta syndrome. The one was 75 years old with acute limb ischemia at the left popliteal artery due to the macroembolism from infrarenal Shaggy Aorta. The other was 76 years old with kidney dialysis, who had suffered from blue toe syndrome due to microembolism from the mobile plaque adhering to the infrarenal aortic wall. We successfully performed graft replacement of the abdominal aorta in order to prevent the recurrence of atheromatous embolization from the Shaggy Aorta. They have been free from any embolic event for the last 1 year. The ultrasonogram was useful for preoperative diagnosis and intraoperative management.View full abstractDownload PDF (694K) -

JOURNAL FREE ACCESSWe report a rare case of primary cardiac undifferentiated pleomorphic sarcoma with invasion to the posterior mediastinum, for which partial resection of the tumor in the left atrium had already been carried out twice. After remission for about three years, recurrence in the atrial wall involving the mitral valve posterior leaflet required a third surgical resection following mitral valve replacement.View full abstractDownload PDF (732K) -

JOURNAL FREE ACCESSA 74-year-old man had been taking warfarin for atrial fibrillation, but warfarin was discontinued due to upper gastrointestinal bleeding. One week later, left hemiplegia occurred, and cranial magnetic resonance imaging revealed multiple cerebral infarctions. Systemic examination revealed thrombi in both atria as well as duodenal cancer. Because all of the thrombi in both atria were larger than 30 mm in diameter, the risk of embolism or sudden death was assumed to be high. Although the use of cardiopulmonary bypass for cancer patients is controversial, bilateral atrial thrombectomy was performed 4 weeks after cerebral infarction onset because reasonable survival duration was expected with surgery for duodenal cancer after thrombectomy and further treatment. The timing of and indications for surgery in this case are discussed.View full abstractDownload PDF (338K) -

JOURNAL FREE ACCESSA 77-year-old woman underwent percutaneous coronary intervention (PCI) for chronic total occlusion of the left anterior descending artery using a drug-eluting stent (DES). Re-stenosis, stent fracture, and aneurysm were found on follow-up coronary angiography (CAG), and thus implantation of multiple DESs was required. Surgery was indicated because CAG 48 months after first DES implantation revealed enlargement of the aneurysm with other new lesions. She successfully underwent off-pump coronary artery bypass grafting and resection of the aneurysm.View full abstractDownload PDF (731K) -

JOURNAL FREE ACCESSA 73-year-old woman suffered from ruptured aortic arch aneurysm into mediastinum. The patient was treated by thoracic endovascular aortic repair with the double-chimney graft technique. Three days later, computed tomography (CT) revealed type 1a endoleak (EL) between the chimney grafts. Ten days later, the patient was treated by coil embolization of the aneurysm from the left subclavian artery. The patient recovered, and was without aortic aneurysm events during six months of follow up.View full abstractDownload PDF (520K) -

JOURNAL FREE ACCESSWe report the rare case of a 68-year-old man, who was admitted to our hospital with a diagnosis of aortic arch anastomotic pseudoaneurysm, with concomintant aortic root enlargement and coronary artery stenosis. Eleven years previously, at age 56, he underwent total arch replacement with island reconstruction for chronic aortic dissection. We performed redo total arch replacement, aortic root replacement and coronary artery bypass, making use of a cardiopulmonary bypass with cannulation through the right subclavian artery, femoral artery and femoral vein before resternotomy. We also used selective cerebral perfusion. Postoperatively, the patient temporarily required reintubation ; however, he was discharged in good condition on the 50th post-operative day. The case suggests that island reconstruction has the potential to cause an aortic arch pseudoaneurysm, particularly after a long postoperative period of time. Therefore, thorough postoperative care strategy is required. We also need to consider surgical reconstructive techniques which eliminate vascular lesions as much as possible at the time of the primary surgery, particularly in cases of chronic aortic dissection.View full abstractDownload PDF (1080K) -

JOURNAL FREE ACCESSA 58-year-old man was admitted with a complaint of exertional chest discomfort. A mass, 53×55×66 mm in size, was detected in the transverse sinus of the pericardium, just cranial to the inter-atrial septum with enhanced chest CT. We performed resection of the tumor under cardiopulmonary bypass. Histopathological findings showed that the tumor was angiomyolipoma originated from the heart. Angiomyolipoma is a benign tumor, most frequently found in the kidney or liver and usually associated with tuberous sclerosis. Extra-cardiac growth of the cardiac angiomyolipoma is extremely rare, and only few have been reported previously.View full abstractDownload PDF (870K) -

JOURNAL FREE ACCESSAnkylosing spondylitis is chronic, progressive, inflammatory disease involving the spine, peripheral joints, and periarticular structures. Cardiac abnormalities associated with ankylosing spondylitis are well recognized, but a case with DDD pacemaker implantation for complete atrioventricular block and aortic valve replacement for aortic regurgitation has not been previously reported. We report a case of a 66-year-old man with ankylosing spondylitis who was successfully treated by DDD pacemaker implantation for complete atrioventricular block and aortic valve replacement for severe aortic regurgitation.View full abstractDownload PDF (776K) -

JOURNAL FREE ACCESSWe report a case of endovascular aneurysm repair (EVAR) in a patient with an aortocaval fistula (ACF) who presented with congestive heart failure due to left-to-right shunting. The patient was an 80-year-old man who complained of sudden respiratory discomfort and lower leg edema, and was admitted to the emergency department. The initial diagnosis on admission was acute heart failure. Because the inferior vena cava was visualized by angiography in the arterial phase due to the fistula from the abdominal aorta, after admission, we rediagnosed this case as ACF. As medical treatment did not improve the patient's symptoms, emergency surgery was decided upon. Because preoperative evaluation was able to rule out the existence of an aortic aneurysm, ACF closure was performed by EVAR. The postoperative course was uneventful and the patient was discharged 15 days after surgery. ACF without aortic aneurysm is uncommon and is not easily diagnosed. This case demonstrated that EVAR can be an effective treatment option for ACF.View full abstractDownload PDF (548K)
