Cardiac Catheterization II: Right Heart Catheterization

19
Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...

科学领域:

  • 心脏病学 心脏病学
  • 人工智能的人工智能
  • 医疗成像医学成像

背景情况:

  • 正确量化右心室 (RV) 对于诊断和管理心血管疾病至关重要.
  • 使用二维心声回声 (2DE) 的传统方法的准确性和可重现性可能受到限制.
  • 心脏磁共振成像 (CMR) 是一个参考标准,但比2DE.

研究的目的:

  • 评估基于注意力的深度学习 (DL) 方法的可行性和准确性,用于RV量化.
  • 将2DE中的DL衍生RV指标与CMR参考标准进行比较.
  • 探索这种新型DL方法的潜在临床适用性.

主要方法:

  • 50名患有并发2DE和CMR的成年患者的回顾性分析.
  • 基于注意力的DL模型的开发,使用特征标记器和变压器层.
  • 输入特征包括标准化2DE视图中的患者年龄,性别和RV区域;输出是RV体积和射出分数 (RVEF).

主要成果:

  • 该DL模型在预测RV体积 (R2 = .953) 和RVEF (APE = 7.24% ± 4.55%) 中表现出高准确度.
  • 该方法与CMR参考值有很好的相关性.
  • DL模型成功地在测试组中发现了VR扩张和功能障碍的病例.

结论:

  • 以注意力为基础的DL方法是可行的,并显示了使用2DE.RV量化的有希望的准确性.
  • 需要在更大,更多样化的患者队列中进一步验证.
  • 未来的研究将旨在减少临床实施所需的2DE视图的数量.
