Abstract:
ObjectiveTo assess the value of transvalvular pressure gradient (TPG) by use of realtime color Doppler echocardiography in percutaneous balloon pulmonary valvuloplasty (PBPV).Methods Patients with pulmonic stenosis (80 cases) were performed by PBPV,in which the pilmonic annular diameter and TPG were measured by using of 2-D and color Doppler echocardiography in the different periods of this operation.Results The pilmonic annular diameter was not significantly difference by intraoperative echocardiography and radiography measurement (t =2.013,P > 0.05).And pressure measurement by catheterization pre- and post-dilatation was not markedly significant ( t =1.258,P >0.05).However,TPG in patients with the different degree of pulmonic stenosis were decreased significantly ( P <0.01).PBPV treatments in the mild pulmonic stenosis for twice got an excellent effect according to operation criteria,but PBPV treatment in patients with the moderate and severe pulmonic stenosis need to be done for three times.ConclusionsReal-time color Doppler echocardiography is an effective way and plays a guiding role in PBPV.
