Parker et al. 4 reported immediate changes in the respective pressures in 21 patients during mitral commissurotomy — usually an immediate drop. The percentage reduction was higher for the ...

non-invasive approach to assess pulmonary congestion. We investigated the relationship between the number of B-lines (vertical artefacts arising from the pleural line) and intracardiac pressures.

Catheterization is particularly useful in the diagnosis of occult systemic to pulmonary shunts, congenital heart disease, and distal pulmonary artery stenosis.

Blood pressure is measured using two numbers: systolic blood pressure (the first number) indicates the force of the blood against the artery walls when the heart beats, and diastolic blood ...
