摘要

患有严重肺动脉狭窄（PS）的狗狗通常会接受球囊瓣膜成形术治疗。这些手术的成功和安全需要准确评估肺动脉瓣环（PVA）直径，以便正确选择球囊导管。PVA 直径可通过血管造影（PVA-Ang）和经胸超声心动图（PVA-TTE）进行评估，两者都可能影响球囊瓣膜成形术的手术计划。本研究旨在描述 PS 犬的 PVA-Ang 和 PVA-TTE 之间的关系。对 59 只客户饲养的犬只进行了观察性、回顾性研究。对诊断为 PS 的犬只的医疗记录进行了回顾。审查了选择性右心室血管造影术和经胸超声心动图的图像。PVA 直径在血管造影（PVA-Ang）时测量，在本研究（PVA-TTE）中由单一操作者测量。根据 PVA 边缘和瓣叶铰链点的可见度对 PVA 的超声心动图图像进行图像质量评分。在 41/59 只（70%）狗中，PVA-Ang 的直径大于 PVA-TTE 的直径，测量值的中位绝对差值为 1.9 毫米（范围 0.1-8.4）。随着超声心动图图像质量的下降，不同测量模式之间的差异也在增大。超声心动图图像质量差的狗与图像质量好的狗相比（范围-2.2-3.8 mm），PVA-Ang 和 PVA-TTE 之间的差异更大（范围-7.7-8.4 mm），图像质量差（中位数 2.8 mm，范围 1.5-8.4 mm）和图像质量好（中位数 1.4 mm，范围 0.2-3.8 mm）之间的绝对差异显著（P=0.005）。在大多数犬中，PVA-Ang 的直径大于 PVA-TTE，这些差异在超声心动图图像质量较差时最为明显。这些差异可能与介入手术计划的临床相关。

Correlation of transthoracic echocardiographic and angiographic measurements of pulmonary valve annular diameter in dogs with pulmonary stenosis

Introduction/Objectives

Dogs with severe pulmonary stenosis (PS) are routinely treated with balloon valvuloplasty. Success and safety of these procedures require an accurate assessment of the pulmonary valve annulus (PVA) diameter for proper balloon catheter selection. PVA diameter is assessed with angiography (PVA-Ang) and transthoracic echocardiography (PVA-TTE), and both may impact procedural planning for balloon valvuloplasty. The objective of this study was to describe the relationship between PVA-Ang and PVA-TTE in dogs with PS.

Animals, materials and methods

Observational, retrospective study of 59 client-owned dogs. Medical records of dogs diagnosed with PS were reviewed. Images from selective right ventricular angiography and transthoracic echocardiography were reviewed. The PVA diameters were measured at the time of angiography (PVA-Ang) and by a single operator for this study (PVA-TTE). Image quality scores were assigned to echocardiographic images of the PVA based on visualization of PVA margins and valve leaflet hinge points.

Results

In 41/59 (70%) dogs, the diameter of the PVA-Ang was larger than the PVA-TTE, and the median absolute difference between measurements was 1.9 mm (range 0.1–8.4). With worse echocardiographic image quality, the difference in measurement between modalities increased. Dogs with poor echocardiographic image quality had greater differences (range −7.7 to 8.4 mm) between PVA-Ang and PVA-TTE compared to those with excellent image quality (range −2.2 to 3.8 mm), and the absolute differences between poor (median 2.8 mm, range 1.5–8.4 mm) and excellent (median 1.4 mm, 0.2–3.8 mm) image quality were significant (P=0.005).

Conclusions

Diameters of PVA-Ang are greater than PVA-TTE in most dogs, and these differences are most apparent with worse echocardiographic image quality. These differences may be clinically relevant to interventional procedure planning.
