The right heart pulmonary circulation unit (RH-PCU) is a key determinant of prognosis in several cardiorespiratory diseases. Although right heart catheterization is considered the gold standard for pulmonary hemodynamic assessment, a comprehensive cardiovascular ultrasound approach is an essential step in the diagnostic-prognostic clinical pathway of patients with suspect or overt pulmonary hypertension. The exponential development of advanced ultrasound techniques (strain, 3-dimensional echocardiography and lung ultrasound) has led to new insights into the evaluation of RH-PCU structure and function, overcoming some limitations of standard Doppler echocardiography. In the near future, exercise Doppler echocardiography may become a useful technique for detecting a latent stage of pulmonary hypertension and for evaluating right ventricular contractile reserve.
右心肺循环单元（RH-PCU）是多种心肺疾病预后的关键决定因素。尽管右心导管检查被认为是肺血流动力学评估的金标准，但全面的心血管超声检查方法是疑似或明确肺动脉高压患者诊断-预后临床路径中的重要一步。先进超声技术（应变、三维超声心动图和肺部超声）的快速发展为RH-PCU结构和功能的评估带来了新的见解，克服了标准多普勒超声心动图的一些局限性。在不久的将来，运动多普勒超声心动图可能成为检测肺动脉高压潜在阶段和评估右心室收缩储备的有用技术。
