Enlarged coronary sinus thrombosis after repair of Ebstein's anomaly.

A 58-year-old woman was referred to our hospital with progressively increasing breathlessness. She reported a history of bioprosthetic valve implantation for tricuspid valve replacement and direct closure of an atrial septal defect for Ebstein's anomaly, 31 years before presentation. Transthoracic echocardiography revealed prosthetic valve failure, an enlarged coronary sinus, and severe mitral regurgitation. Computed tomography revealed a giant coronary sinus with thrombosis and persistent left superior vena cava. She underwent successful mitral and tricuspid valve replacement; however, severe hemodynamic deterioration necessitated mechanical ventilatory support with extracorporeal membrane oxygenation.

[A Case of Remnant Gastric Cancer That Completely Responded to Neoadjuvant S-1 and Cisplatin Therapy].

A 69-year-old man, who had undergone distal gastrectomy for duodenal ulcer, was diagnosed with remnant gastric cancer and jejunal mesenteric lymph node metastasis. To improve curability, we planned 2 courses of S-1 and cisplatin therapy. After chemotherapy, primary lesion and lymph node metastases reduced in size drastically. Completion gastrectomy and lymph node dissection were performed with curative intent. The tumor was found to have a pathological complete response(pCR) to chemotherapy on histological examination.

Incidentally detected atrioventricular septal defect in an adult.

A 34-year-old woman, a liver transplantation donor for her son, was referred to our hospital for preoperative evaluation. She was diagnosed with an incomplete atrioventricular septal defect (AVSD). She underwent double valve repair and patch closure of the defect. Incidental discovery of an asymptomatic AVSD in an adult is rare.

Radiotherapy-related skin ulcer communicating with a left ventricular aneurysm.

Although radiation therapy is widely used to treat breast cancer, high doses of radiation may cause various complications. We report a case of a left ventricular aneurysm complicated with an intractable skin ulcer caused by radiation therapy for breast cancer. The communication between the aneurysm and skin ulcer caused severe bleeding. An urgent left ventricular repair and chest wall reconstruction with a rectus abdominis flap were performed successfully.

Early Progression of Aortic Stenosis Associated With Iatrogenic Variant Transthyretin Amyloidosis After Domino Liver Transplantation.

We report a 65-year-old man who underwent aortic valve replacement because of severe aortic stenosis associated with de novo iatrogenic variant transthyretin amyloidosis derived from a liver graft extracted from a patient with hereditary transthyretin amyloidosis 9 years after the domino liver transplantation. (Level of Difficulty: Advanced.).
