An 80-year-old woman underwent lower and middle lobe resections of right lung in 1990 and 1998 because of lung cancers. There was no recurrence. In 2009, she presented with exertional dyspnea, and echocardiography showed grade III mitral regurgitation (MR). We diagnosed with congestive heart failure caused by MR. Her chest CT showed her mediastinum was shifted to the right and her heart was in the right thoracic cavity. We performed mitral valve plasty via right 7th intercostal thoracotomy. Post-operative respiratory condition was stable and she was extubated on the first postoperative day. Post-operative UCG showed trivial MR. She was discharged on the 14th day.

Primary cardiac angiosarcoma is very rare and its prognosis was reported to be very poor (average survival period 7 months). A 46-year-old woman with angiosarcoma was admitted for recurrent symptoms of cardiac tamponade. Surgical excision of the tumor was performed 5 months after initial presentation and irradiation therapy was added. Thereafter, immunotherapy, and transcatheter arterial embolization were performed for liver metastasis. Despite this multidisciplinary therapy, she passed away 355 days after surgery. In our report, we described our multidisciplinary approach to this highly malignant tumor and the treatment strategy was discussed.

Right-sided infective endocarditis (IE) accounts for 5% to 10% of all IE. Compared with left-sided IE, antibiotic treatment is effective in about 70% of cases. The timing of surgical treatment for right-sided IE is therefor controversial. A 26-year-old woman had suffered from tricuspid valve endocarditis with DIC. There was no evidence of any previous cardiac event or dental treatment. Echocardiography showed a large vegetation attached to the anterior leaflet of tricuspid valve with moderate tricuspid regurgitation. We removed the vegetation with a part of the anterior leaflet and performed tricuspid valvuloplasty and annuloplasty. The patient had an uneventful postoperative course and received intravenous antibiotic treatment for a further 4 weeks.

A 27-year-old woman was given a diagnosis of infectious endocarditis with severe tricuspid regurgitation. Despite adequate antibiotics therapy, her general condition did not improve, and moreover multiple pulmonary abscesses were detected by computed tomography. Therefore surgery was indicated. Surgery consisted of removal of vegetation and tricuspid valve plasty with autologous pericardial patch augmentation of the anterior leaflet. Tricuspid valve plasty was carried out without prosthetic materials. Her postoperative course was uneventful with only mild tricuspid regurgitation. One year after surgery, neither recurrence of infection nor worsening of tricuspid regurgitation was noted. This method could be a useful technique for young patients with severe infection.

We described a patient with free wall rupture followed by papillary muscle rupture due to acute myocardial infarction. A 69-year-old man was transferred complaining of transient unconsciousness. His clinical history, electrocardiogram, and chest CT showed myocardial infarction with free wall rupture indicated that several days had passed since the onset. Coronary angiography showed occlusion of the right coronary artery and severe stenosis of the left anterior descending artery. Since cardiac rupture was at inferior wall and hemorrhage wasn't active, repair of the rupture using fibrin glue and fibrin sheet and coronary artery bypass grafting to the left anterior descending artery was performed without cardiopulmonary bypass. On the 10th postoperative day, his arterial oxygen saturation suddenly deteriorated. Transesophageal echocardiography revealed papillary muscle rupture and severe mitral regurgitation. Emergency mitral valve replacement was performed. After two emergency operations, he gradually recovered and were discharged to home. In three months after discharge, he was admitted again due to congestive heart failure with left ventricular aneurysm at inferior wall and recovered in response of conservative treatment. Surgical experience of double rupture is rare. Based on this case, it may be necessary to perform reperfusion therapy toward even this case of recent myocardial infarction, to prevent papillary muscle rupture. It also may be better to use a patch on free wall rupture to prevent cardiac aneurysm.

Essential thrombocythemia (ET) is an uncommon type of myeloproliferative disorder, characterized by both thrombotic and hemorrhagic diatheses. No clear guidelines exist for the pre- or post-operative management of patients with ET undergoing cardiac surgery. Here, we present a rare case of a patient with essential thrombocythemia and severe aortic stenosis, who needed an aortic valve replacement on cardiopulmonary bypass and who suffered no complications.

PA-LA communication is a rare congenital heart disease consisting of direct communication between a branch of the PA and LA through an aneurysmal structure. This disease reveals the central cyanosis with clubbed fingers and surgical repair is needed when symptoms are apparent. Computed tomography is highly recommended for definitive diagnosis. Angiographic catheterization is also recommended to support the diagnosis and decide on the treatment. PA-LA communication is categorized into 4 types. Two types do not need cardiopulmonary bypass (CPB) when treated surgically, but the others need CPB. A 16-year-old girl with clubbed fingers was found to have PA-LA communication by 3DCT. She underwent surgery and was discharged in good condition. The surgical procedure was done through median sternotomy without CPB. The anomalous aneurysmal fistula was doubly ligated. No communication was found after ligation by TEE.

A 74-year-old woman was referred to our unit with a chief complaint of dysphagia. Enhanced CT showed a Kommerell diverticulum with a maximum diameter of 46 mm, associated with a right-sided aortic arch and aberrant left subclavian artery. We performed two-staged operations : left subclavian-common carotid artery bypass followed by total arch, and descending aortic replacement by an antero-lateral thoracotomy with partial sternotomy (ALPS). The postoperative course was uneventful. Total arch and descending aortic replacement for a Kommerell diverticulum by an ALPS approach is rare. ALPS approach for Kommerell diverticulum achieves safe surgery with good exposure.

A 47-year-old man had suffered from high grade fever and dyspnea for 10 days. He was transferred to our hospital in a condition of shock. Echocardiography showed severe diffuse hypokinesis of left ventricle (EF 21%), and multiple mobile thrombi in the left ventricle. Under a diagnosis of LV thrombi due to acute myocarditis, transatrial removal of LV thrombi was performed using video-assisted cardioscopy. He was weaned from cardiopulmonary bypass under IABP support. Postoperatively, he suffered from thromboembolism of the cerebral and right brachial artery. Thrombectomy of the right brachial artery and anticoagulation therapy was performed. IABP was removed on POD 3, and he no longer needed respiratory control on POD 4. Echocardiography on POD 6 showed marked improvement of the LV contraction (EF 52%). After rehabilitation, he was discharged on POD 23 on foot. Video-assisted cardioscopy allowed transatrial removal of LV thrombi, and preserved left ventricular function by avoiding ventriculotomy. Perioperative thromboembolism must be taken care of for a patient with multiple LV thrombi.

Endovascular treatment for chronic aortic dissection in patients with Marfan syndrome is still controversial. A 60-year-old man developed an extended chronic type B dissection involving the aortic arch and thoraco-abdominal aorta with a large entry at the distal aortic arch and patent false lumen. He had undergone David procedure for type A aortic dissection at age 42, and aortic valve replacement for recurrent aortic valve insufficiency at 58, which was complicated with mediastinitis. He also suffered drug-induced interstitial pneumonitis. Considering his complicated surgical history and impaired pulmonary function, conventional graft replacement of thoraco-abdominal aorta was thought to be quite a high risk. Thus, we chose debranch TEVAR with a staged approach. First, debranching and Zone 0 TEVAR with the chimney technique were performed. Then, 4 months later, abdominal debranching and TEVAR was performed. The patient tolerated both procedures well and was discharged home. Two years after last procedure, he is in good condition and computed tomography shows that complete entry closure and false lumen had thrombosed. This strategy may be worthy to be considered even for a patient with Marfan syndrome, in case the patient's condition is unsuitable for conventional surgery.
