Non-bacterial Thrombotic Endocarditis Presenting as a Mass in the Right Atrium Diagnosed by Open Chest Surgery.

Non-bacterial thrombotic endocarditis (NBTE) is a condition that results in the development of vegetation on cardiac valves that are devoid of inflammation and bacteria. We herein report a 60-year-old man who transferred to our hospital because of a systemic embolism and heart failure. A mass in the right atrium and vegetation on the mitral valve were observed.

A case of cardiopulmonary arrest due to left ventricular free wall rupture successfully treated with sutureless repair supported by venoarterial extracorporeal membrane oxygenation.

Extracorporeal membrane oxygenation for cardiopulmonary arrest due to left ventricular free wall rupture is considered effective, because it enables rapid cardiopulmonary support and introduction of targeted temperature management.

[Cardiac Strangulation Induced by Epicardial Pacemaker Leads Causing Heart Failure;Report of a Case].

A 5-year-old girl has a history of epicardial VVI-pacemaker implantation due to congenital heart block at the age of 2 months. Five years later, she developed heart failure at the same time of battery depletion. The chest X-ray indicated the loop formation of the epicardial leads and the echocardiogram demonstrated paradoxical movement of ventricles.

Endovascular Treatment for Kommerell's Diverticulum with a Right-Sided Aortic Arch.

We report a rare case of type A dissection involving a right-sided aortic arch with an aberrant left subclavian artery originating from Kommerell's diverticulum in a 76-year-old woman. Endovascular treatment for Kommerell's diverticulum including intimal tear of the dissection was performed. At the 5-year follow-up, the patient was doing well, with no endoleak or dilatation of the Kommerell's diverticulum.

Metagenomic analysis for detecting pathogens in culture-negative infective endocarditis.

Pathogen identification is important for proper diagnosis and optimal treatment of infective endocarditis (IE). Blood and valve cultures are the gold standard for detecting pathogens responsible for IE. However, these tests only detect culturable pathogens, and have low sensitivity, especially in patients previously treated with antibiotics.

A Case of an Aortic Abscess around the Elephant Trunk.

A 52-year-old male patient with a history of total arch replacement using the elephant trunk technique for acute aortic dissection 4 years before visited our hospital with the chief complaint of persistent fever. Chest computed tomography (CT) suggested prosthetic vascular graft infection, which was treated surgically after chemotherapy. The first surgery consisted of debridement of an abscess around the vascular graft and in the aorta around the elephant trunk, and thoracic descending aorta replacement and vacuum-assisted closure (VAC) in view of the risk of bleeding from the peripheral region of the elephant trunk.

Morphological Evaluation of Proximal Anastomosis by PAS-Port(®) System in Patients with Long-Term Patent Grafts.

Purpose: We examined grafts employing for morphological analysis of early and long-term results on proximal anastomosis with the PAS-Port(®).

Methods: One hundred and four patients treated by OPCAB with PAS-Port(®) were performed postoperative MDCT. Morphological evaluation of the proximal anastomotic region was classified into three groups (A; graft was anastomosed almost perpendicularly to the aortic wall, B; graft was same type A, but subsequently curved to form an acute angle with the aortic wall, C; graft take off acute angle with the aortic wall) evaluated on planar and sagittal sections.

Interrupted aortic arch with massive saccular collateral aneurysm in an adult.

A 49-year-old man was diagnosed with an interrupted aortic arch (IAA), a massive saccular thoracic collateral aneurysm, ischemic renal insufficiency, and multiple abdominal collateral aneurysms. A bypass from the left subclavian artery to the descending aorta and thoracic collateral aneurysmectomy proceeded simultaneously through a posterolateral thoracotomy. The pressure gradient between upper and lower extremities disappeared and renal function was normalized.

Endovascular abdominal aortic aneurysm repair in patients with renal transplants: reports of two cases.

The artery and vein of the transplanted kidney are generally anastomosed to the external iliac artery and vein, respectively. Therefore, in open abdominal artery aneurysm (AAA) repair in renal transplant patients, kidney ischemia due to a proximal aortic clamp is a serious problem. We successfully performed endovascular aneurysm repair (EVAR) of AAA without aortic clamping in two renal transplant recipient cases.
