新生兒及嬰兒期危重先心病介入治療

四川大學華西第二醫(yī)院心臟介入中心華益民新生兒PBPV近期并發(fā)癥：

1、短暫心動過緩、早搏、體循環(huán)壓力不能維持；

2、失血（特別是介入治療早期器械原因）；

3、股動脈、靜脈栓塞；

4、CRBBB、短暫的AVB、腦血管意外、意識喪失、驚厥、三尖瓣及乳頭肌斷裂、肺動脈瓣撕裂；

5、QTc延長導致室性心動過速。Significantpulmonaryvalveincompetencefollowingoversizeballoonpulmonaryvalveplastyinsmallinfants.CatheterCardiovascInterv.1999,48:61-65PercutaneousBalloonPulmonaryValvuloplasty:StateoftheArt.CatheterizationandCardiovascularInterventions,2007,69:747–63Significantpulmonaryvalveincompetencefollowingoversizeballoonpulmonaryvalveplastyinsmallinfants.CatheterCardiovascInterv.1999,48:61-65PercutaneousBalloonPulmonaryValvuloplasty:StateoftheArt.CatheterizationandCardiovascularInterventions,2007,69:747–63PBAV前:?P84mmHgPBAV后:?P14mmHg
