The aim was to see if probing the fossa ovalis for transseptal puncture during balloon mitral valvuloplasty will reduce time consumed for the procedure.
Twenty-five patients had probing of fossa ovalis for left atrial entry (group I). In 30 patients (group II), standard needle puncture was done for left atrial entry. Puncture time and fluoroscopy time were noted and oxymetry was done. Later, a further 60 patients underwent probing of fossa ovalis for validation of the technique.
Puncture times in groups I and II were 84.7 +/- 27.5 and 116.1 +/- 37.9 s, respectively (p < 0.02). Fluoroscopy time was 51.2 +/- 19.6 and 73.6 +/- 22.3 s in groups I and II, respectively (p < 0.03). During validation of the technique, 54 of 60 patients (90%) had successful left atrial entry through probing. Atrial level shunt was not seen.
Probing the fossa achieves left atrial entry in 90% of patients. It avoids needle puncture and reduces puncture time as well as fluoroscopy time. It is a safe technique.
旨在观察在球囊二尖瓣成形术期间经卵圆窝进行房间隔穿刺是否会减少该操作所消耗的时间。
25例患者经卵圆窝穿刺进入左心房（I组）。30例患者（II组）采用标准针穿刺进入左心房。记录穿刺时间和透视时间并进行血氧测定。随后，另有60例患者经卵圆窝穿刺以验证该技术。
I组和II组的穿刺时间分别为84.7±27.5秒和116.1±37.9秒（p<0.02）。I组和II组的透视时间分别为51.2±19.6秒和73.6±22.3秒（p<0.03）。在技术验证过程中，60例患者中有54例（90%）经穿刺成功进入左心房。未发现心房水平分流。
经卵圆窝穿刺在90%的患者中可成功进入左心房。它避免了针穿刺，减少了穿刺时间和透视时间。这是一种安全的技术。
