ABSTRACT
A 74-year-old woman had been on hemodialysis for about 2 months using a short-term indwelling dialysis catheter due to chronic kidney disease. A 20 mm-diameter left atrial neoplastic lesion was noted during a screening echocardiogram performed at the time of induction of hemodialysis. The lesion rapidly increased to 30 mm 2 months later and was referred to our hospital for surgical resection. Under cardiopulmonary bypass and cardiac arrest, tumor resection was performed. Although the lesion was myxomatous with a thin stalk on the left atrial ceiling, the pathological diagnosis was thrombus. After the initiation of anticoagulation, the patient was discharged.

A pulmonary arteriovenous fistula (PAVF) is a direct abnormal connection between the pulmonary artery and pulmonary vein, lacking capillary tissue. On the other hand, a pulmonary venous aneurysm (PVA) is a localized dilation and aneurysmal formation in the pulmonary vein without reflux issues. Treatment approaches for PAVF and PVA differ, considering surgery or catheter embolization for PAVF due to the risk of cerebral infarction or rupture caused by the abnormal shunt. PVA cases, being rare in rupture and embolism, are usually recommended for observation. Therefore, distinguishing between these two conditions is crucial. This article presents a case where both PVA and PAVF were present, necessitating a differential diagnosis.

A 64-year-old female with a diagnosis of Crawford typeâ ¡ thoracoabdominal aortic aneurysm( TAAA) including enlargement of the ascending aorta underwent a staged hybrid repair including visceral artery debranching thoracic endovascular aortic repair( TEVAR). First, total arch replacement with elephant trunk method was performed, followed by TEVAR for the descending thoracic aorta, and finally visceral artery debranching TEVAR for the thoracoabdominal aorta. Complications such as spinal cord infarction did not occur throughout the procedure. Surgical repair of Crawford typeâ ¡ TAAA involves a wide range of treatment and is highly invasive, requiring ingenuity in terms of preventing complications such as spinal cord infarction. Hybrid repair including visceral artery debranching TEVAR may be an effective treatment modality for complex aortic lesions including TAAA, but requires careful follow-up including remote complications.

An 86-year-old man presented with bilateral lower limb edema and was found to have hydropneumothorax on chest radiography. CT revealed a substantial pleural effusion and plaques. The patient had a history of working in a stone workshop, but the extent of asbestos exposure remained unknown. Thoracic drainage and subsequent thoracoscopic surgery confirmed the presence of biphasic malignant mesothelioma through pathological examination. Hydropneumothorax as a presentation of malignant pleural mesothelioma (MPM) is rare, with only a few similar cases reported. Remarkably, despite the coexistence of plural effusion and pneumothorax, the patient did not experience dyspnea. The examination also revealed tumor rupture and disruption of the pleura. Considering the possibility of MPM in patients with asymptomatic hydropneumothorax is essential for early diagnosis and appropriate management.
ABSTRACT
A 64-year-old female without symptoms of heart failure was diagnosed with a two-chambered right ventricle (TCRV) during examination of a heart murmur and cardiac enlargement, for which surgery was performed. Under cardiopulmonary bypass and cardiac arrest, we first performed a right atrium and pulmonary artery incision and observed the right ventricle through the tricuspid and pulmonary valves, although we could not obtain a sufficient view of the right ventricular outflow tract. After subsequently incising the right ventricular outflow tract and the anomalous muscle bundle, the right ventricular outflow tract was patch-enlarged using a bovine cardiovascular membrane. After weaning from cardiopulmonary bypass, disappearance of the pressure gradient in the right ventricular outflow tract was confirmed. The patient's postoperative course was uneventful without any complications including arrhythmia.

Metastatic heart tumors make up the majority of heart tumors and are 20 to 40 times more frequent than primary heart tumors. Cardiac metastasis of renal cell carcinoma is often asymptomatic until advanced stage, and there are few reports of surgical tumor resection for metastatic heart tumors at very late term. We experienced a case of metastatic right ventricular tumor eleven-year after nephrectomy for renal cell carcinoma. Tumor resection was performed under cardiopulmonary bypass and cardiac arrest, but the tumor on the free wall of the right ventricle trabeculae could not be completely resected. After surgery, the patient underwent chemotherapy for residual tumor, which is growing.
