Abstract

Serial sampling from the coronary sinus is an attractive technique for drawing blood samples to be used in the characterization of procoagulant activity during coronary interventions. We have developed a modified Simmons catheter for rapid cannulation of the coronary sinus from the femoral approach. The catheter design incorporates heparin bonding and distal side-holes to minimize blood sampling artifacts. Coronary sinus cannulation was performed via the femoral approach in 186 patients by use of a multipurpose catheter (n = 8), an unmodified Simmons I or II catheter (n = 64), or the modified Simmons catheter (n = 114). The coronary sinus was cannulated successfully with the modified Simmons catheter in 97% of patients; the success rate with the unmodified Simmons II catheter was 87% (P = 0.02). The modified Simmons catheter represents an improved technique for cannulation of the coronary sinus from the femoral vein.

改良肝素结合导管用于股静脉冠状窦插管。
在冠状动脉介入治疗期间,从冠状动脉窦连续取样是一种有吸引力的血液样本提取技术,可用于表征促凝活性。我们开发了一种改良的Simmons导管,用于从股入路快速插管冠状窦。导管设计结合肝素结合和远端侧孔,以尽量减少血样伪影。186例患者经股入路行冠状动脉窦插管,分别使用多用途导管(n = 8)、未改良的Simmons I或II导管(n = 64)或改良的Simmons导管(n = 114)。改良Simmons导管冠脉窦插管成功率97%;未经改良的Simmons II导管的成功率为87% (P = 0.02)。改良的Simmons导管代表了一种从股静脉插管冠状窦的改进技术。
