2023年1月31日 · RVSP = 4v2 + CVP; Mean PAP can be approximated because PAPm = 0.61•sPAP + 2. A systolic PAP of 30 mm Hg typically implies a mean PAP more than 20 mm Hg, i.e. pulmonary hypertension; Echocardiographic probability of pulmonary hypertension (PH) in symptomatic patients with a suspicion of PH (from Frost et al, 2019)

ACC/AHA expert consensus document for PH recommends further evaluation in those experiencing dyspnea with estimated RVSP > 40 mmHg. ASE recommends evaluation to determine the present of PH if the RVSP > 35-40 mmHg and other clinical symptoms correlate.

2015年12月4日 · RVSP is short for right ventricular systolic pressure. RVSP is a commonly searched term because it is found on almost all echocardiogram reports. It is important as the RVSP is used to estimate the pressure inside the artery that supplies the lung with blood. In most cases, the RVSP equals the pulmonary artery pressure.

2019年7月8日 · An estimated right ventricular systolic pressure (eRVSP) — a measure of the pressure inside the artery that supplies blood to the lungs (pulmonary artery) — greater than 30.0 mmHg is related to an increased risk of mortality in patients with pulmonary hypertension (PH), according to a new Australian study.

2017年10月10日 · RVSP P RVSP = P + JVP Estimation of RV Systolic Pressure (RVSP) From Maximum Transtricuspid Gradient

The current recommended threshold for prompting further evaluation for PH is an RVSP value of 40 mm Hg, which approximates an mPAP of 25 mm Hg. This recommendation is based on expert consensus opinion.

Pulmonary hypertension is defined as a mean arterial pressure of ≥25 mmHg as confirmed on right heart catheterisation. Traditionally, the pulmonary arterial systolic pressure has been estimated on echo by utilising the simplified Bernoulli equation from the peak tricuspid regurgitant velocity and adding this to an estimate of right atrial pressure.

This study has 3 main findings: (1) The prevalence of elevated RVSP ≥ 40 mm Hg (22.1%) and RVSP ≥ 30 and < 40 mm Hg (22.0%) on echocardiography is more common than a clinical diagnosis of PH based on ICD-10 codes (3.1%); (2) elevated RVSP is associated with dilatation of right atrium and ventricle and reduced TAPSE; and (3) increasing RVSP ...

2004年6月16日 · The RVSP is approximated by measurement of the systolic regurgitant tricuspid flow velocity vand an estimate of right atrial pressure (RAP) applied in the formula: RVSP = 4v 2 + RAP. The RAP is either a standardized value, or an estimated value from characteristics of the inferior vena cava (5) or from jugular venous distension.

2023年3月22日 · 我们的研究评估了右心室收缩压 (RVSP) 和平均肺动脉压 (mPAP) 在经胸超声心动图 (TTE) 上的相关性与 mPAP 在右心导管插入术 (RHC) 上的相关性。 研究方法： 我们对 2012 年至 2020 年间在我们机构接受 LT 评估的 723 名患者进行了回顾性研究。 我们的队列包括经 TTE 测量的 RVSP 和 mPAP 患者。 Wald t 检验和曲线下面积分析用于 统计 分析。 研究结果： TTE 上 mPAP 值较高的患者 (N=33) 与 RHC 上的 mPAP ≥ 35 mmHg 无关，而 TTE 上 RVSP 值较高 …
