Iron imaging in myocardial infarction reperfusion injury

Publikováno v: Nature Communications, Vol 11, Iss 1, Pp 1-14 (2020)

Restoration of coronary blood flow after a heart attack may lead to reperfusion injury and pathologic iron deposition. Here, the authors perform magnetic susceptibility imaging showing its association with iron in a large animal model of myocardial i

Combined treatment for a large primary cardiac sarcoma: a case report

Autor: Shinji Akishima, Akito Imai, Yoshiharu Enomoto, Osamu Shigeta

Publikováno v: Surgical Case Reports, Vol 5, Iss 1, Pp 1-5 (2019)

Abstract Background Undifferentiated pleomorphic sarcoma (UPS) as a primary cardiac tumor is rare, with extremely poor prognosis owing to high recurrence and invasion. We encountered a patient who presented with a primary cardiac tumor incarcerating

Thymoma with a feeding vessel from coincident coronary–pulmonary artery fistulas

Autor: Keisuke Kobayashi, Hideo Ichimura, Taisuke Konishi, Yasunori Watanabe, Kanji Matsuzaki, Akito Imai

Publikováno v: Asian Cardiovascular and Thoracic Annals. 30:325-328

We report a rare case of a 68-year-old man with thymoma and coronary–pulmonary artery fistulas. The thymoma was 66 × 51 × 88 mm in size and accompanied by a feeding vessel originating from the coronary–pulmonary artery fistulas. We performed to

Right atrial blood cyst in elderly patient: the timing of surgery

Autor: Osamu Shigeta, Akito Imai, Yoshiharu Enomoto, Yasuyuki Suzuki

Publikováno v: Asian Cardiovascular and Thoracic Annals. 28:500-503

A regular check up on a 59-year-old man showed a high carcinoembryonic antigen level in his blood. A computed tomography scan showed tumors in the right atrium. We performed tumor resection successfully. The resected specimen was found to be blood cy

Iron imaging in myocardial infarction reperfusion injury

Publikováno v: Nature Communications, Vol 11, Iss 1, Pp 1-14 (2020)
Nature Communications

Restoration of coronary blood flow after a heart attack can cause reperfusion injury potentially leading to impaired cardiac function, adverse tissue remodeling and heart failure. Iron is an essential biometal that may have a pathologic role in this

Radical surgery for a mitral valve intimal sarcoma: serial patch repair of the annulus and atrium

Autor: Kanji Matsuzaki, Kisato Mitomi, Akito Imai, Yasunori Watanabe

Publikováno v: Interactive cardiovascular and thoracic surgery. 35(2)

We report the rare case of a 48-year-old woman with a cardiac intimal sarcoma occupying the mitral valve and the left atrial roof. We resected the tumour in one block without residual lesions. The anterior mitral annulus and left atrial roof were ser
