目的：：应用经胸超声心动图声学造影( cTTE)联合经食管超声心动图( TEE)对临床怀疑存在房水平右向左分流的病人进行检查,为临床诊断及治疗提供诊断依据。方法：对72例临床怀疑存在房水平右向左分流的病人先行cTTE检查观察静息状态及Valsalva动作后左心内微气泡数量,对有右向左分流的病人再行TEE检查,最终明确房水平分流的病因。结果：cTTE发现房水平右向左分流17例,房水平无分流55例。前者行TEE检查后,12例病人存在FFO,5例病人房水平无分流。结论：cTTE能快速的发现房水平右向左分流,联合经食管超声心动图可以明确分流的病因,可为临床治疗提供重要的影像学依据。

Objective:To investigate the application value on assessment right-to-left shunt( RLS) in patients with clinical suspicion of RLS on atrial level by Contrast Transthoracic echocardiography ( cTTE ) combined with Transesophageal echocardiography ( TEE ) . Provide diagnostic evidence for clinical diagnosis and treatment. Methods:72 cases of patients with clinical suspicion of the presence of RLS on atrial level were examined by cTTE to observed the number of micro-bubbles in left heart during resting state and after Valsalva maneuver. For the patients with the RLS were examined by TEE. Eventually clear the cause of atrial level shunt. Results:cTTE found atrial level RLS 17 cases,without shunt 55 cases. the former were examined by TEE,in witch 12 patients with PFO and 5 patients without atrial level shunt. Conclusion:cTTE can quickly find RLS on atrial level, witch combined with TEE can clear the cause of diversion and provide an important imaging basis for the clinical treatment.
