Constrictive Pericarditis: Venous waveform - OpenAnesthesia
https://www.openanesthesia.org/constrictive_pericarditis_venous_waveform/
The pressure tracing during diastole of the RV, LV, and RA will equalize. See Figure 7-3 B for the CVP tracing during constrictive pericarditis. Elevated mean (CVP) pressure, prominent a and v waves, steep x and y descents. Restriction from tight pericardium limits cardiac filling, decreased end-diastolic volume, stroke volume and cardiac output.
Invasive hemodynamics of constrictive pericarditis - PMC
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4475854/
1. Introduction. With the advent of newer imaging tools, there has been a shift to noninvasive imaging particularly when chronic constrictive pericarditis (CCP) is suspected. 1 Cardiac catheterization nonetheless remains diagnostic of the constriction physiology especially when anatomic information from other imaging tools is inconclusive.
Constrictive pericarditis: diagnosis, management and …
https://pubmed.ncbi.nlm.nih.gov/29175978/
Constrictive pericarditis (CP) is a form of diastolic heart failure that arises because an inelastic pericardium inhibits cardiac filling. This disorder must be considered in the differential diagnosis for unexplained heart failure, particularly when the left ventricular ejection fraction is preserved. Risk factors for the development of CP ...
Value of reference tracings in diagnosis and assessment …

Abstract. Reference tracings are of great value in the diagnosis and assessment of constrictive pericarditis. The Q-h interval in the jugular venous pulse tracing is strongly correlated with the mean right atrial pressure (r=0·91).The left ventricular ejection time, the Q-A2 interval, and the Q-h interval are independent during atrial fibrillation from the preceding diastolic filling interval.
Constrictive pericarditis - PubMed
https://pubmed.ncbi.nlm.nih.gov/1000537/
Constrictive pericarditis, although still a relatively rare disease, continues to be a clinical problem that most practicing cardiologists may encounter. A major clinical clue to diagnosis is the continued elevation of the central venous pressure after adequate diuresis. The diagnosis is …

Pathophysiology and Diagnosis of Constrictive Pericarditis
https://www.acc.org/latest-in-cardiology/articles/2017/03/13/15/10/pathophysiology-and-diagnosis-of-constrictive-pericarditis
Constrictive pericarditis (CP) is a relatively uncommon form of clinical heart failure. The true population prevalence is unknown, but amongst those with viral pericarditis it has been estimated to occur in less than 0.5% of cases. 1 However, because it is potentially reversible, the diagnosis must not be missed. Surgical pericardiectomy has the ability to "cure" CP, with …
RA/CVP Waveform Interpretation - RK.md
https://rk.md/2020/ra-cvp-waveform-interpretation/
Central venous pressure (CVP) or right atrial pressure (RAP) waveform tracings can often times provide useful insight about a patient’s right ventricle (RV), tricuspid valve (TV), and overall cardiopulmonary status. ... (rapid RV filling in early diastole) Steep ↑ with constrictive pericarditis and ↓ with tamponade (↓ RV filling from ...
Cardiac tamponade | Deranged Physiology

This is also seen in constrictive pericarditis. The usual manifestation on the CVP trace is a rapid y descent, followed by a rapid rise in pressure. It happens when the tricuspid valve opens in early right ventricular diastole; the right ventricle fills rapidly because of increased right atrial pressure, but is unable to take all of the right ...
CVP Measurement • LITFL • CCC Equipment
https://litfl.com/cvp-measurement/
OVERVIEW. Central venous pressure (CVP) is the pressure recorded from the right atrium or superior vena cava and is representative of the filling pressure of the right side of the heart. CVP monitoring in the critically ill is established practice but the traditional belief that CVP reflects ventricular preload and predicts fluid responsiveness ...
