摘要
应用多普勒超声心动图对74例二尖瓣球囊成形术(PBMV)病人术前、术后1天及4年的二尖瓣返流(MR)进行研究,将MR划分为Ⅳ级。术后1天与术前比较,MF程度不变59例(80%)、加重Ⅰ级12例(16%)、加重Ⅲ级1例(1%)、减轻Ⅰ级2例(3%);术后4年与术后1天比较,MR程度不变55例(74%)、加重Ⅰ级11例(15%)、加重Ⅲ级1例(1%)、减轻Ⅰ级7例(10%)。表明轻度MR(≥2+)是PBMV术后常见并发症,仅极少数病人出现严重MR(≥3+),且部分病人随访过程中MR程度减轻。
Mitral regurgitation (MR) was evaluated by Doppler echocardiography in 74 patients before, 1- day and 4-year after Percutaneous balloon mitral valvulophasty(PBMV). The severity of MR was graded on a scale from 1+ to 4+. 1 day after versus before PBMV, MR grading did not change in 59 patients (80%), increased by 1+in 12 Patients (16%), by 3+ in 1 Patient (1%), and decrased by 1+ in 2 patients(3%). 4-year versus 1-day after PBMV, 55 patients(74%) had no change in the extent of MR and 7 patients (10%) had a 1-grade decrase in MR, 11 patients (15%) had 1-grade increase and 1 patient (1%) had a 3-grade increase in MR. It is concluded
that an increasement in MR severity≤2+ is frequently seen after MBMV; only a small number of
patient developed severe MR(≥3 + ), and in some, MR severity might decease during follow-up.
