“…In the presence of constrictive or restrictive RV physiology, PR Doppler signals could provide a valuable clue towards the diagnosis but may be unreliable in the calculation of pulmonary artery pressure [15]. In constrictive physiology, there is dissociation of intracardiac from intrathoracic pressure, resulting in early equalisation of PA and RV pressures with inspiration.…”

Pulmonary hypertension is a pathological haemodynamic condition defined as an increase in mean pulmonary arterial pressure ≥ 25 mmHg at rest, assessed using gold standard investigation by right heart catheterisation. Pulmonary hypertension could be a complication of cardiac or pulmonary disease, or a primary disorder of small pulmonary arteries. Elevated pulmonary pressure (PAP) is associated with increased mortality, irrespective of the aetiology. The gold standard for diagnosis is invasive right heart catheterisation, but this has its own inherent risks. In the past 30 years, immense technological improvements in echocardiography have increased its sensitivity for quantifying pulmonary artery pressure (PAP) and it is now recognised as a safe and readily available alternative to right heart catheterisation. In the future, scores combining various echo techniques can approach the gold standard in terms of sensitivity and accuracy, thereby reducing the need for repeated invasive assessments in these patients.

Multimodality imaging of constrictive pericarditis in H syndrome

et al. 2021

This is the first report of constrictive pericarditis (CP) in a 16‐year‐old boy with H syndrome with pericardial involvement predominantly over the right ventricle with favorable response to anti‐inflammatory treatment. H syndrome, first reported in 2008, is a new auto‐inflammatory syndrome with multiorgan involvement due to mutation in the SLC29A3 gene. We described the echocardiographic characteristics of asymmetric pericardial involvement and presented the cardiac computed tomography angiographic and magnetic resonance imaging findings. We reviewed the echocardiographic signs of CP, introduced tricuspid E/A respiratory alternans as a novel echocardiographic sign of right ventricular dominant CP, and explained the underlying mechanism.

Pulmonary haemodynamic status has got significant clinical and prognostic significance both in structural and nonstructural heart diseases. But diagnostic accuracy depends on much care in evaluation and logical correlation of different echocardiographic parameters. Though the Doppler studies play crucial role in estimating Pulmonary haemodynamics, careful observation of 2-D measurements of different structures as well as RV systolic and diastolic function are vital issues to be addressed and correlated for diagnostic accuracy. Tricuspid Valve, RVOT and Pulmonary valve pathologies also demand vivid correlation while estimating PA pressures and pulmonary vascular resistance. Mere presence of elevated pulmonary artery systolic pressure is not enough to define pulmonary hypertension (PH). Before declaring a patient having PH a comprehensive evaluation of right heart haemodynamics is to be performed carefully to avoid unnecessary cardiac catheterization or to avoid inadvertent initiation of PH therapy.
