Abstract

Objective

This study aims to validate the feasibility of applying an adapted version of the Hahn tricuspid valve nomenclature to classify the leaflets of the tricuspid valve in the subxiphoid short-axis view (SSAV) using transthoracic echocardiography (TTE).

Methods

Referral patients from three medical institutions underwent TTE, with the requirement that the tricuspid valve structure be clearly visible in standard views (AC4 V, PSAV, RVIT, S4CV). The tricuspid valve leaflets were classified retrospectively based on the nomenclature proposed by Hahn et al.

Results

Between June 2023 and June 2024, 600 patients' SSAV images were analyzed, with 421 cases (70.2%) successfully classified, while 179 cases (29.8%) failed to be classified. The average age of patients was 58 ± 31 years (range: 27–79 years). There were 334 males (55.7%). The mean weight was 75.7 ± 13.5 kg, and the average BMI was 23.1 ± 3.8 kg/m². Of the patients, 52.2% had mild or moderate tricuspid regurgitation (TR), 24.3% had severe TR, 22.8% had massive TR, and 2.3% had torrential TR. In the morphological classification of the tricuspid valve, type I was the most common (32.0%), followed by type IIIB (29.8%). Additionally, 179 cases (29.8%) were not successfully classified or determined.

Conclusion

SSAV, as an adjunctive imaging view in TTE for assessing the tricuspid valve, shows potential clinical value. Although there are challenges in classifying tricuspid valve leaflets, the method demonstrates certain feasibility.

改良Hahn命名法在剑突下短轴透视经胸超声心动图中应用于三尖瓣小叶分类的可行性研究

目的验证经胸超声心动图（TTE）应用改良版Hahn三尖瓣命名法在剑突下短轴位（SSAV）上对三尖瓣小叶进行分类的可行性。方法来自3家医疗机构的转诊患者行TTE，要求在标准视图（ac4v、PSAV、RVIT、S4CV）下清晰可见三尖瓣结构。根据Hahn等人提出的命名法对三尖瓣小叶进行回顾性分类。结果2023年6月至2024年6月共分析600例患者SSAV图像，分类成功421例（70.2%），未分类179例（29.8%）。患者平均年龄58±31岁（范围27 ~ 79岁）。男性334人，占55.7%。平均体重75.7±13.5 kg，平均BMI为23.1±3.8 kg/m2。其中，轻、中度三尖瓣反流（TR）占52.2%，重度TR占24.3%，重度TR占22.8%，重度TR占2.3%。三尖瓣形态分类中，I型最常见（32.0%），其次是IIIB型（29.8%）。此外，179例（29.8%）未成功分类或确定。结论SSAV作为TTE中评估三尖瓣的辅助影像，具有潜在的临床应用价值。虽然对三尖瓣小叶的分类存在一定的挑战，但该方法具有一定的可行性。
