Efficacy of a sutureless aortic valve-reoperative alternative to a composite graft replacement.

Findings in the present case underscore the potential of sutureless aortic valve utilization in patients with prior prosthetic root replacement, thereby obviating the need for high-risk procedures such as replacing a prosthetic root or reimplanting a coronary artery. A 75-year-old male who had undergone a Bio-Bentall operation with a bioprosthetic Trifecta valve for aortic regurgitation and annuloaortic ectasia eight years prior presented with symptoms of heart failure, notably dyspnoea, attributed to prosthetic valve dysfunction. Although a transcatheter aortic valve implant is often recommended, it was deemed unsuitable in this case due to a history of type B aortic dissection.

Totally thoracoscopic atrial fibrillation surgery following massive small bowel resection due to superior mesenteric artery embolization: report of two cases.

Background: Thromboembolic occlusion of the superior mesenteric artery (SMA) is a grave complication in individuals diagnosed with atrial fibrillation (AF). This condition often necessitates extensive bowel resection, culminating in short bowel syndrome, which presents challenges for anticoagulant administration and/or antiarrhythmic therapy.

Case Presentation: Presented here are findings of two patients, aged 78 and 72 years, respectively, who underwent comprehensive thoracoscopic AF surgery subsequent to extensive small bowel resection following SMA embolization.

Electrical impedance tomography-guided prone positioning in a patient with acute cor pulmonale associated with severe acute respiratory distress syndrome.

Electrical impedance tomography (EIT) is a noninvasive technique used to assess regional gas distribution in the lung. We experienced a patient with acute cor pulmonale during high positive-pressure ventilation for the treatment of severe acute respiratory distress syndrome. Prone positioning was beneficial for unloading the right ventricle for treatment of acute cor pulmonale.
