Abstract

Background: The aim of this study was to compare and correlate the right ventricular volumes and ejection fraction by 3D echo and cardiac MRI in postoperative tetralogy of Fallot patients with free pulmonary valve regurgitation.

Methods: Twenty-six patients with severe PR secondary to either pulmonary valvotomy or tetralogy of Fallot repair were evaluated using 3D echo and MRI.

Results: The mean end-diastolic volumes (ml/m²) were 161.61 ± 29.31 and 170.16 ± 30.79 (p = 0.03) and the mean end-systolic volumes(ml/m²) 83.74 ± 24.16 and 94.18 ± 24.13 (p = 0.12) on 3D echo and MRI, respectively. The mean RV ejection fractions were 47.90 ± 7.81% on 3D echo and 44.83 ± 8.29% on MRI (r = 0.89, P < .001). Similarly, there were strong correlations of both end-diastolic volume and end-systolic volume on 3D echo and MRI (r = 0.94 and r = 0.74, respectively).

Conclusions: Three-dimensional echo was comparable with MRI in determining RV volume and ejection fraction in post operative TOF patients with free pulmonary regurgitation. It will be important to study 3D echo in a larger population of patients with TOF, which will be possible only through multi-centre collaboration.

《法洛四联症合并游离肺动脉瓣返流术后三维超声和心脏MRI对右心室容积和射血分数的相关性》。

背景：本研究的目的是比较法洛四联症合并游离肺动脉瓣反流患者术后三维超声和心脏MRI的右心室容积和射血分数。方法：对26例肺瓣切开术或法洛四联症继发的严重PR患者进行三维超声和MRI评价。结果：三维超声和MRI的平均舒张末期容积（ml/m2）分别为161.61±29.31和170.16±30.79 (p= 0.03)，平均收缩末期容积（ml/m2）分别为83.74±24.16和94.18±24.13 （p= 0.12）。左心室射血分数分别为三维超声（47.90±7.81%）和MRI(44.83±8.29%)（r = 0.89, P < 0.001）。同样，三维超声和MRI显示舒张末期容积和收缩末期容积有很强的相关性（r分别为0.94和0.74）。结论：三维超声与MRI在确定TOF术后游离肺返流患者右心室体积和射血分数方面具有可比性。在更大的TOF患者群体中研究3D回声将是重要的，这将只有通过多中心合作才能实现。

期刊介绍： Indian Heart Journal (IHJ) is the official peer-reviewed open access journal of Cardiological Society of India and accepts articles for publication from across the globe. The journal aims to promote high quality research and serve as a platform for dissemination of scientific information in cardiology with particular focus on South Asia. The journal aims to publish cutting edge research in the field of clinical as well as non-clinical cardiology - including cardiovascular medicine and surgery. Some of the topics covered are Heart Failure, Coronary Artery Disease, Hypertension, Interventional Cardiology, Cardiac Surgery, Valvular Heart Disease, Pulmonary Hypertension and Infective Endocarditis. IHJ open access invites original research articles, research briefs, perspective, case reports, case vignette, cardiovascular images, cardiovascular graphics, research letters, correspondence, reader forum, and interesting photographs, for publication. IHJ open access also publishes theme-based special issues and abstracts of papers presented at the annual conference of the Cardiological Society of India.
