BACKGROUND: Air emboli released from incompletely deaired cardiac chambers may cause neurocognitive decline after open heart surgery. Carbon dioxide (CO2) field flooding is reported to reduce residual intracavital air during cardiac surgery. A protective effect of carbon dioxide insufflation on postoperative brain function remains unproven in clinical trials. METHODS: Eighty ...

OBJECTIVE: Previous reparative valvular surgical options directed at reconstructing damaged common femoral vein (CFV) valves associated with pathological chronic venous insufficiency (CVI) have not succeeded in reliably managing CVI. In consequence, venous valvuloplasty is rare and most patients are managed conservatively. As a result, monocusp surgery was identified as an ...

OBJECTIVE: The congenitally bicuspid aortic valve is the most common etiologic factor associated with clinically significant aortic stenosis and/or regurgitation in pediatric patients. Beyond infancy, surgical intervention typically involves valve repair with cusp thinning and commissurotomy or valve replacement, primarily with pulmonary autograft in the current era. An aortic valve ...
