Avoiding anticoagulation drugs for postoperative atrial fibrillation enabled successful conservative treatment of left atrial dissection: a case report.

Background: Left atrial dissection is a rare complication of cardiac surgery, most commonly associated with mitral valve surgery. Herein, we report on the successful conservative treatment of left atrial dissection while avoiding anticoagulation therapy.

Case Presentation: A 64-year-old man developed left atrial dissection during operation for acute type A aortic dissection, most likely due to retrograde cardioplegia cannulation.

[Traction-assisted Negative Pressure Wound Therapy for Pediatric Poststernotomy Mediastinitis:Report of Two Cases].

We herein report two cases of pediatric poststernotomy mediastinitis treated by traction-assisted negative pressure wound therapy (NPWT) with Zip Surgical Skin Closure (Zip), which is a non-invasive skin closure device. We used this device with NPWT in cases of pediatric poststernotomy mediastinitis to stabilize the sternum and reduce the natural retractive forces of the skin. The patients were two boys (two and three months old), with an onset of infection at 13 and eight postoperative days, respectively.

Direct Abdominal Aortic Access for Thoracic Endovascular Aortic Repair in a Patient with Severe Aortic and Arterial Calcification.

Aortic and arterial calcification is a complication of advanced atherosclerosis and is a critical intraoperative issue that can reduce the ability to achieve safe and adequate access for stent graft introduction. Different vascular access sites are used to deliver stent grafts when a standard transfemoral or iliac access is not feasible. We report a challenging case of a direct transabdominal aortic thoracic endovascular aortic repair for a thoracic aortic aneurysm complicated with severe aortic and arterial calcification, in which the noncalcified area of the infrarenal abdominal aorta was extremely limited.

[Tricuspid Valve Replacement Preserving the Leaflets in a Congenitally Corrected Transposition of the Great Arteries;Report of a Case].

In patients with a congenitally corrected transposition of the great arteries (ccTGA), the regurgitation of the systemic atrioventricular valve (SAVV) increases and anatomical right ventricular (ARV) dysfunction often progressively develops. A low systemic ventricular ejection fraction( SVEF) is a risk factor for mortality. However, in patients with a low ejection fraction of ARV, it is unclear how to best perform valve replacement for patients with regurgitation of SAVV.

[Thoracic Endovascular Repair for Chronic Aortic Dissection with Aberrant Origin of the Left Vertebral Artery;Report of a Case].

We herein report a case of thoracic endovascular aortic repair( TEVAR) for chronic aortic dissection with an aberrant left vertebral artery( LVA) originating from the aortic arch. A 51-year-old man with a medical history of Stanford type B acute aortic dissection 2 years ago was transferred to our institution for the treatment of an aortic expansion. Computed tomography showed a large entry just distal to the takeoff of the left subclavian artery and a dilated dissected thoracic aorta.

Total arch repair with frozen elephant trunk using the "zone 0 arch repair" strategy for type A acute aortic dissection.

Objective: The aim of this study was to investigate the effect of frozen elephant trunk deployment from the zone 0 aorta to the descending aorta on early and midterm postoperative results in patients with acute type A aortic dissection.

Methods: Between October 2014 and April 2018, 108 patients underwent a combined strategy of frozen elephant trunk deployment, ascending aortic replacement, and arch vessel reconstruction ("zone 0 arch repair" strategy) for acute type A aortic dissection (excluding DeBakey type II). Of the 108 patients, 32 (29.
