How is right ventricular function assessed?

The assessment of right ventricular diastolic function is obtained by Doppler interrogation of the tricuspid inflow, tissue Doppler interrogation of the lateral tricuspid valve annulus, Doppler interrogation of the hepatic veins, assessment of the right atrium, as well as assessment of the size and collapsibility of …

What is right ventricular function?

The right ventricle is the chamber within the heart that is responsible for pumping oxygen-depleted blood to the lungs.

What is tissue Doppler used for?

Tissue Doppler imaging (TDI) is a relatively new echocardiographic technique that uses Doppler principles to measure the velocity of myocardial motion.

How is right ventricular dysfunction diagnosed?

Cardiac magnetic resonance (CMR) imaging is still the gold standard for the evaluation of RV morphology, mass, volumes and systolic function. However, assessing both systolic and diastolic RV function and volumes has improved with the introduction of new echocardiographic techniques (11).

What does right ventricular failure result in?

Failure of the Right Ventricle results in systemic venous hypertension, and can lead to the following signs/symptoms: Peripheral edema. Anorexia, nausea, and abdominal pain related to congestion hepatomegaly. Fatigue, dypnea (related to inadequate Cardiac Output)

What happens if the right ventricle fails?

Right-sided heart failure means your heart’s right ventricle is too weak to pump enough blood to the lungs. As a result: Blood builds up in your veins, vessels that carry blood from the body back to the heart. This buildup increases pressure in your veins.

How does tissue Doppler imaging work?

Tissue Doppler echocardiography (TDE) is a medical ultrasound technology, specifically a form of echocardiography that measures the velocity of the heart muscle (myocardium) through the phases of one or more heartbeats by the Doppler effect (frequency shift) of the reflected ultrasound.

What happens if right ventricle not working properly?

What are the signs and symptoms of right-sided heart failure?

What are the symptoms of right-sided heart failure?

  • shortness of breath, especially when lying flat.
  • coughing.
  • dizziness.
  • difficulty concentrating and confusion.
  • fatigue and low energy.
  • sudden weight gain.
  • reduced appetite.
  • upset stomach.

What is normal EE ratio?

An E/e’ ratio < 8 is considered to be normal, and a ratio > 15 is considered to reflect an increase in the LV filling pressure [11-13]. In patients with normal EF, tissue Doppler echocardiography has been used to evaluate LV filling pressure and LV stiffness [11].
