Abstract

In veterinary medicine, the radiographic assessment of right heart enlargement (RHE) is essentially subjective. The aim of this study was to evaluate the vertebral right heart index (VRHi) as a new quantitative radiographic method to detect RHE in dogs. This was a multicenter, retrospective, observational study, including dogs with RHE and control dogs. All dogs had to have a thoracic radiographic study and a complete echocardiography on the same day. Right heart enlargement was defined as the presence of right atrial enlargement, right ventricular enlargement, and/or hypertrophy based on echocardiography. For the radiographic study, all the radiographic views available for each case were considered for measurement: right lateral (RL), left lateral (LL), ventrodorsal (VD), and dorsoventral (DV). The VRHi was measured using LL, RL, VD, and DV views. A total of 204 dogs were included: 91 dogs with RHE and 113 control dogs. The VRHi (RL), the VRHi (LL), and the VRHi (VD) were significantly greater in dogs with RHE compared with controls (P < .0001). The best diagnostic accuracy was observed for VRHi (LL) (area under the curve [AUC] 0.86, P < .0001; cutoff ≥ 3.5 vertebrae, sensitivity [Se] 71%, specificity [Sp] 89%), followed by VRHi (RL) (AUC 0.85, P < .0001; cutoff ≥ 3.5 vertebrae, Se 68%, Sp 86%) and VRHi (VD) (AUC 0.80, P = .0004; cutoff ≥ 3.0 vertebrae, Se 57%, Sp 95%). In conclusion, the lateral VRHi in LL and RL and the VD VRHi could represent useful radiological tools for the detection of RHE in dogs.

脊椎右心指数：评估犬右心室肥大的新放射学方法

在兽医学中，右心扩大（RHE）的放射学评估基本上是主观的。本研究旨在评估椎体右心指数（VRHi），将其作为检测犬 RHE 的一种新的定量放射影像学方法。这是一项多中心、回顾性、观察性研究，包括患有 RHE 的狗和对照组狗。所有犬只都必须在同一天进行胸部X光检查和完整的超声心动图检查。根据超声心动图检查结果，右心房增大、右心室增大和/或肥厚是右心增大的定义。在放射学研究中，每个病例的所有放射学切面都被考虑用于测量：右外侧（RL）、左外侧（LL）、腹背（VD）和背腹（DV）。VRHi使用LL、RL、VD和DV视图进行测量。共纳入 204 只狗：其中 91 只患有 RHE，113 只为对照组。与对照组相比，RHE 患犬的 VRHi (RL)、VRHi (LL) 和 VRHi (VD) 明显更高（P < .0001）。VRHi (LL) 的诊断准确率最高（曲线下面积 [AUC] 0.86，P < .0001；临界值≥ 3.5 个椎体，灵敏度 [Se] 71%，特异性 [Sp] 89%），其次是 VRHi (RL)（曲线下面积 [AUC] 0.85，P < .0001; 临界值≥ 3.5 个椎体，Se 68%，Sp 86%）和 VRHi (VD)（AUC 0.80，P = .0004; 临界值≥ 3.0 个椎体，Se 57%，Sp 95%）。总之，LL 和 RL 的外侧 VRHi 以及 VD VRHi 是检测犬 RHE 的有用放射学工具。
