- Abstract
Objective: To evaluate a hemodynamic method for the assessment of the position of the retrograde cardioplegia catheter (RCC) versus conventional Manual Assessment. Methods: We randomized 200 patients undergoing aortic valve surgery to Manual (n = 101) or Hemodynamic Assessment (n = 99). In the Hemodynamic group a 25% pressure increase at the tip of the RCC when a fistula with the ascending aorta was created via a luer-lock was considered indicative of correct RCC placement. Transesophageal echocardiography was used as a comparison evaluation method. Results: The Hemodynamic and Manual Assessment considered the RCC positioning successful in 89.9% versus 85.1% of cases. Echocardiography confirmed these results in Hemodynamic group but revealed 23 cases of misrecognized incorrect placement in the Manual group (p < 0.0001). Manual maneuvers resulted in 18 cases of secondary displacement and 19 cases of hemodynamic instability (p < 0.0001). Conclusions: The Hemodynamic Method is quantitative, reproducible, highly reliable, and safer than palpation in the posterior atrioventricular groove.
