Surgical management of scimitar syndrome: an alternative approach.
The scimitar syndrome is a congenital anomaly that consists in part of total or partial anomalous venous drainage of the right lung to the inferior vena cava. Surgical approaches to the scimitar syndrome have varied according to the anatomic and pathologic features presented in each case. The aim of this study was to present an alternative approach to the surgical correction of scimitar syndrome. ⋯ This clinical experience indicates that an alternative surgical approach to scimitar syndrome is direct anastomosis of the scimitar vein to the posterior aspect of the left atrium using a right thoracotomy without cardiopulmonary bypass. This procedure is safe and effective and obviates the need for long intra-atrial baffles and the use of the extracorporeal circuit.

Acute volume reduction with aortic valve replacement immediately improves ventricular mechanics in patients with aortic regurgitation.
Few data have been available regarding the immediate response in ventricular mechanics to acute volume reduction caused by aortic valve replacement for aortic regurgitation. ⋯ Correction of volume overload reduced preload (minimum area), shifted the end-systolic pressure-area relationship to the left (decreased end-systolic area), and improved ventricular contractility (increased slope of the end-systolic pressure-area relationship). The result indicated that acute volume reduction favorably influenced ventricular mechanical parameters immediately after the operation.
