Collapse and Occlusion of Balloon-Expandable Covered Stent in the Right Common Iliac Arteries Due to External Stress.

The patient previously underwent surgery for cervical cancer. She reported intermittent claudication, and computed tomography (CT) revealed total occlusion of the left iliac artery. We conducted endovascular treatment (EVT) using balloon-expandable covered stents (BECS).

Aortic valve neocuspidization using bovine pericardium for prosthetic valve endocarditis in a hemodialysis patient.

Background: Hemodialysis patients are at high risk for prosthetic valve endocarditis (PVE) because of the risk of bacteria entering with each hemodialysis session. To avoid the use of artificial materials as much as possible, we performed aortic valve neocuspidization (AVNeo) using bovine pericardium.

Case Presentation: A 67-year-old patient had undergone aortic valve replacement using a bioprosthetic valve 4 months previous.

Thoracoscopic surgery for atrial fibrillation in a patient with persistent left superior vena cava: a case report.

Background: A persistent left superior vena cava (PLSVC) is an anomaly of the thoracic venous system that flows into the right atrium via an enlarged coronary sinus. When performing pulmonary vein isolation and left atrial appendage closure, the PLSVC can interfere with the procedure. We have performed thoracoscopic surgery on such a patient and would like to share our experience.

Transcatheter aortic valve implantation causing left ventricular perforation may be associated with an aberrant right subclavian artery: a case report.

Unlabelled: Left ventricular perforation is an uncommon complication in transcatheter aortic valve implantation (TAVI). And a case of left ventricular perforation associated with an aberrant right subclavian artery (ARSA) has rarely been reported. An 86-year-old female attended our hospital with symptomatic severe aortic stenosis.

Strict control of phosphorus concentration of hemodialysis patients may decrease structural valve deterioration after aortic valve replacement.

Objectives: The number of hemodialysis patients requiring aortic valve replacement (AVR) is increasing. Although bioprosthetic valves are increasingly popular, they are associated with a risk of structural valve deterioration (SVD). The aim of this study is to examine the outcomes of bioprosthetic valves in hemodialysis patients undergoing AVR and to identify treatment strategies that can decrease the risk of SVD.

Non-aneurysmal ascending aorta diameter changes after aortic valve replacement in patients with stenotic bicuspid and tricuspid aortic valve.

Objective: The appropriate timing of aortic repair in patients with bicuspid aortic valve-related aortopathy remains controversial. We describe the changes in diameter of the non-aneurysmal ascending aorta after aortic valve replacement for bicuspid or tricuspid aortic valve stenosis.

Methods: This retrospective review included 189 patients who had undergone aortic valve replacement for severe stenotic aortic valve with a non-aneurysmal ascending aorta diameter of 45 mm or less between January 2008 and December 2018.

Thoracic aortic stent graft placement and simultaneous screw removal for a screw hitting the aorta.

Vascular injury caused by spinal screw displacement is a rare complication of spinal fusion surgery. Here, we report a case with no perforation of the aortic wall, which we treated by means of simultaneous thoracic endovascular aorta repair (TEVAR) and screw removal. An 82-year-old female underwent corrective spinal fixation.

Rapidly growing papillary fibroelastoma complicated by myxoma.

Rapidly growing papillary fibroelastoma complicated by myxoma is extremely rare. An 80-year-old male was transported to our hospital because of cerebral hemorrhage. Echocardiogram revealed a massive pedunculated tumor in the septum of the left atrium.

Effects of perioperative oral care on postoperative inflammation following heart valve surgery.

Objective: Whether oral health care during the perioperative period can lead to a better outcome after heart valve surgery has not been adequately elucidated. We examined the effects of perioperative oral care on postoperative inflammation response in patients who underwent heart valve surgery.

Materials And Methods: In this retrospective cohort study, 223 patients scheduled for single valve heart surgery were divided into the oral care, who underwent professional teeth cleaning or scaling within 3 days prior to surgery, and also following surgery at least twice a week (n = 111), and non-oral care (n = 112) groups.

A case of supra-annular mitral valve replacement using chimney technique for severe mitral stenosis with extensive mitral annular calcification.

When patients with extensive mitral annular calcification undergo mitral valve replacement, excessive debridement of calcification may result in fatal complications and may protract operation time. We report a case of supra-annular MVR using "the chimney technique" on a high-risk patient for severe mitral stenosis with extensive mitral annular calcification. This technique is usually used in small infants whose mitral annulus is smaller than the smallest available prosthetic valve.

Complete brain protection during debranching thoracic endovascular aortic repair.

We describe the case of a 71-year-old man with an asymptomatic saccular-type thoracic aortic aneurysm and severe atheroma in the distal arch. As he had previously undergone coronary artery bypass grafting, we decided to perform thoracic endovascular aortic repair rather than open repair to avoid injury to the bypass grafts. Owing to severe atheroma, we completely blocked the native forward flow before deploying the endograft using percutaneous cardiopulmonary support, thus preventing perioperative stroke.

Association between false lumen segmental arteries and spinal cord ischemia in type A acute aortic dissection.

Background: Spinal cord ischemia (SCI) and paraplegia are complications of surgery for type A acute aortic dissection (TAAAD). Since the segmental arteries play a key role in SCI, this study evaluated the association between SCI and false lumen segmental arteries (FLSAs: segmental arteries originating from the false lumen).

Methods: The study included 101 consecutive TAAAD patients (mean age, 66±13; range, 34-89 years) who underwent surgery from January 2011 to April 2017.

Abdominal organ protection strategy for aortic arch aneurysm surgery.

Introduction: Body temperature maintained during open distal anastomosis in patients who undergo aortic surgery has been showing an upward trend; however, a higher temperature may increase visceral organ and spinal cord injury. Distal perfusion may reduce abdominal organ injury, especially acute kidney injury (AKI).

Methods: From 2009 to 2016, 56 patients who underwent ascending aortic and/or aortic arch surgery were enrolled.
