Case ReportsEvaluation of cerebral circulation during retrograde perfusion by laser speckle flowgraphy.
Laser speckle flowgraphy (LSFG) is an ophthalmologic equipment that qualitatively detects the blood flow of the optic nerve head, which is known to be related with cerebral microcirculation. LSFG can also measure the mean blur rate, which quantitatively calculates the blood flow. ⋯ The blood flow of the optic nerve head was monitored with LSFG and the mean blur rate value was measured during the surgery. The LSFG could detect the blood flow quantitatively in the optic nerve head during both retrograde and antegrade cerebral perfusion; and the value was correlated with rSO2 value.

Comparative StudyComparison of early outcomes of surgical ablation procedures for atrial fibrillation concomitant to non-mitral cardiac surgery: a Japan Adult Cardiovascular Surgery Database study.
Although the benefit of surgical ablation for atrial fibrillation (AF) performed concomitant to mitral valve surgery is established, whether that performed concomitant to non-mitral cardiac surgery is beneficial remains unclear. In non-mitral, non-left-atriotomy cardiac surgery, the optimal surgical approach for AF remains to be established. Therefore, using the Japan Adult Cardiovascular Surgery Database (JACVSD), we compared 2 surgical ablation procedures [the maze procedure and pulmonary vein isolation (PVI)] performed concomitant to non-mitral cardiac surgery. ⋯ Our data indicate that surgical ablation of AF concomitant to non-mitral cardiac surgery is beneficial. Furthermore, PVI and the maze procedure appear to be of equal benefit in this context, except that the maze procedure may more frequently result in the need for pacemaker implantation.
