Tetralogy of Fallot TOF with pulmonary atresia Pulmonary atresia with intact interventricular septum Tricuspid atresia Double outlet right ventricle Transposition of great arteries with ventricular septal defect and pulmonarystenosis Ebstein’s anomaly of tricuspid valve In DORV and tricuspid atresia, there are also variants with increased pulmonary (..)
Echocardiography allows estimation of right ventricular (RV) systolic pressure by adding the estimated right atrial pressure (RAP) to the systolic pressure gradient between the RV and right atrium (RA) calculated from the tricuspid regurgitant (TR) Doppler velocity.
Objective A novel artificial intelligence-based phenotyping approach to stratify patients with severe aortic stenosis (AS) prior to transcatheter aortic valve replacement (TAVR) has been proposed, based on echocardiographic and haemodynamic data. ±15.8 ±15.1 mm Hg, p value: 0.0079). to 84.7%) and 74.6% (95% CI 65.9% to 94.8%)).
Both atria develop from a combination of the primitive atrium, sinus venous, and pulmonary veins.It Regarding the issue at hand, it is widely known that in cases of mitral stenosis with AF, the left atrium (LA) is larger than the right atrium (RA) due to the obvious reason that the baseline LA was larger at the onset of AF.
(maybe not seen well on these echo-loops) The CW doppler at the tricuspid valve showed a maximum TR velocity of 2,55m/s with a TRP gradient of 26mmHg. large ASD, partial anomalous pulmonary venous return, significant tricuspid regurgitation, carcinoid valvular disease, etc,) 2) Conditions causing pressure overload of the RV. (E.g
Assessment of fluid overload identifies aortic stenosis (AS) patients at high risk and treatment of fluid overload may potentially improve the post-interventional clinical course. Aims Cardiac decompensation in aortic stenosis (AS) involves extra-valvular cardiac damage and progressive fluid overload (FO).
And that will be the approximate level of the tricuspid valve, the reference point for measuring right atrial pressure. In right atrial tracing, this occurs at the time of right ventricular contraction, with bulging upwards of the tricuspid valve. The Y descent is shallow in tricuspidstenosis, and absent in cardiac tamponade.
Moreover, we sought to test the correlation between angiography-derived index of microcirculatory resistance (IMR angio ) and invasive IMR in patients with aortic stenosis (AS). Advanced EVCD was defined as pulmonary circulation impairment, severe tricuspid regurgitation or right ventricular dysfunction.
This suggests that there is pulmonary hypertension and thus possibly RVH. Severe tricuspid regurgitation. --The The estimated pulmonary artery systolic pressure is 31 mmHg + RA pressure. That condition is tricuspidstenosis, which is rare. There is, however, a very peaked P wave in lead II (a "peaked P pulmonale").
The aorta, right ventricular outflow tract and pulmonary artery up to its bifurcation is imaged in the upward angulation shown in the left panel. Colour flow shows the flow in pulmonary artery. Planimetry of mitral valve area can be obtained in parasternal short axis view in case of mitral stenosis.

Bernoulli equation (P=4V 2 ) gives the gradient of tricuspid regurgitation flow, which corresponds to the pressure difference between right ventricle and right atrium in systole. The early diastolic pulmonary regurgitation (PR) gradient (peak PR gradient) will give an estimate of mean pulmonary artery pressure.
AF, atrial fibrillation; LAVI, left atrial volume index; RA, right atrial; RV, right ventricular; sPAP, systolic pulmonary artery pressure; SVI, stroke volume index; TR, tricuspid regurgitation. Aims Paradoxical low-flow, low-gradient aortic stenosis (pLFLG AS) may represent a diagnostic challenge, and its pathophysiology is complex.
