We report a case of multiple papillary fibroelastoma (PFE) on the aortic valve. A healthy woman in her 60 s was referred to a nearby doctor with the chief complaint of palpitation and was admitted to our hospital for detailed examination. A mobile tumor was found by transthoracic echo, and she was introduced to us. We undertook excision surgery for her. Initially, it was thought to be a single tumor, and a pedunculated tumor adhering to the central aortic side of the left coronary cusp with a length of 7 mm was removed. After closing the aorta, we recognized a remaining mobile tumor by transesophageal echo. We decided to perform cardiac arrest again, and we recognized one tumor with 6 mm long string-like mobile mass on the right and non-coronary commissure of cardiac side, and a thorn-like mass of about 1.5 mm on the non-coronary cusp of the cardiac side. We removed both tumors from the aortic valve using shaving resection and preserved the aortic valve. All of these were found to be PFE pathologically as if they were three tumors that followed the developmental stage of PFE. After surgery, PFE recurrence is extremely rare. In the case of a pedunculated tumor, it is possible to remove the tumor and preserve the valve. However, as in this case, if both sides of the valve were not carefully inspected, it can be overlooked. In addition, small tumor resection could avoid the risk of new cerebral infarction and myocardial infarction due to recurrence and could avoid reoperation.
A man in his 54 was admitted to our hospital owing to progressive postprandial pain for a month. Computed tomography (CT) scan and angiography revealed severe stenosis and calcification of the celiac artery, superior mesenteric artery, and inferior mesenteric artery. Based on the findings of CT scan and angiography, abdominal angina was established and retrograde revascularization was performed only to the superior mesenteric artery using an artificial graft. After the surgery, he remains free of postprandial abdominal pain.
活動期感染性心内膜炎(infective endocarditis:IE)に対する外科治療は,心不全や感染の制御,塞栓症の予防の観点から,適応,手術時期を判断し,感染組織の可及的切除により再感染を予防する.また,脳合併症を呈する場合には,梗塞後出血や新規発症のリスクを考慮に入れたうえで適切な手術時期を決定すべきである.大動脈弁位では弁周囲膿瘍が起こりやすく,周囲組織との解剖学的関係を十分理解し,郭清,再建を行う.僧帽弁位では弁形成の可能性を常に考慮すべきである.
