Parameters associated with perioperative baffle fenestration closure in the Fontan operation.
To identify clinical parameters indicating perioperative fenestration closure in children who underwent the fenestrated Fontan operation. ⋯ Factors that correlated with postoperative fenestration closure in the fenestrated Fontan operation in this study were a high transpulmonary pressure gradient and a high oxygen saturation 1 hour after arrival in the ICU, a low fibrinogen level, and the need for temporary atrial pacing.

Echocardiographic assessment of coronary blood flow velocity during controlled hypotensive anesthesia with nitroglycerin.
To determine the effect of nitroglycerin on coronary blood flow velocity during controlled hypotensive anesthesia in humans. ⋯ During nitroglycerin-induced hypotensive anesthesia, coronary blood flow as assessed by peak diastolic left anterior descending flow velocity is preserved or increased in most patients. Increases in left anterior descending flow velocity are predictably achieved only at nitroglycerin doses >5 microg/kg/min. Intraoperative transesophageal echocardiography is useful in monitoring coronary flow velocity responses to controlled hypotensive anesthesia.
