Tubular graft in the descending thoracic aorta may improve left ventricular performance
September 20th, 2006
Interposition of a tubular graft in the descending thoracic aorta results in a decrease in pulse wave velocity (PWV), which may improve left ventricular performance and enhance myocardial perfusion. "The objective of the study was to investigate the alterations of aortic function after interposition of a tubular graft in the descending porcine thoracic aorta. Eight healthy Landrace pigs were subjected to thoracotomy under sterile conditions," researchers in Greece report. "A 5-cm-long segment of descending thoracic aorta was replaced with a Dacron graft. PWV was measured using simultaneous recordings of electrocardiogram and Doppler pressure...
