Effect of pre-interventional coronary remodeling on outcomes of percutaneous balloon angioplasty in patients with angina pectoris / 中华超声影像学杂志

ABSTRACT

70% were enrolled into the study. Intravascular ultrasound (IVUS) was used before procedure, immediately after the final inflation of balloon and at the time of 3 month follow up. Cross sectional area(CSA) at the site of lesions, proximal and distal reference segment(vessel CSA,lumen CSA, plaque CSA) and remodeling ration were calculated respectively. Percutaneous cutting balloon angioplasty and intravascular irradiation was adopted to treat restenotic lesions during 3 month follow up period. Results Thirty seven of 76 cases had positive remodeling .There was no difference in the age, gender and other clinical parameters between positive and non positive remodeling(39 cases) groups. The remodeling ration in positive group [( 1.40 ? 0.13 )mm 2] was larger than that in the control group [( 0.79 ? 0.11 )mm 2,P
