Randomized Controlled Trial Clinical Trial
Pleural tent after upper lobectomy: a prospective randomized study.
The aim of the present study was to assess the cost/efficacy of the pleural tent procedure after upper lobectomy. ⋯ Pleural tenting after upper lobectomy is a safe and effective procedure and its routine use is warranted.

Comparative Study
Comparison of clinical results for unilateral and bilateral thoracoscopic lung volume reduction.
It is widely believed that bilateral thoracoscopic lung volume reduction (BTLVR) yields superior results when compared with unilateral thoracoscopic lung volume reduction (UTLVR) with regard to spirometry, functional capacity, oxygenation and quality of life results. ⋯ These data suggest that both UTLVR and BTLVR yield significant improvement, but the results of BTLVR seem to be superior with regard to spirometry, lung volumes, and quality of life.

Idiopathic root dilatation often results in dysfunction of an otherwise normal aortic valve. To examine the effect of root dilatation on leaflet stress, strain, and coaptation, we utilized a finite element model. ⋯ Idiopathic root dilatation significantly increases leaflet stress and strain and reduces coaptation in an otherwise normal aortic valve. These alterations may affect valve-sparing aortic root replacement procedures.

A 29-year-old gravid female presented at 22 weeks gestation with an acute Type I aortic dissection and coarctation of the aorta. She underwent emergent repair of her aortic dissection using cardiopulmonary bypass and hypothermia. At 25 weeks gestation, she underwent repair of her coarctation of the aorta. The patient had a cesarean delivery of a viable, normal male infant at 39 weeks gestation.

This study was undertaken to determine predictors of adverse outcome and transient neurological dysfunction after replacement of the ascending aorta with an open distal anastomosis. ⋯ Early elective operation and shorter HCA time during ascending aorta/hemiarch surgery will reduce both AO and TND.
