Pulmonic Regurgitation


Pulmonic regurgitation1

Pulmonic Regurgitation

  • Incidental benign finding

  • Pathologic PR – usually due to untreated or residual congenital PR.

  • Acquired PR – rare. Usually due to endocarditis, carcinoid syndrome or myxomatous valve disease.


Congenital disease

Congenital Disease

  • Thickened deformed leaflets


Endocarditis

Endocarditis

  • Valvular vegetation is present.


Carcinoid

Carcinoid

  • Shortening and thickening of the valve.


Myxomatous disease

Myxomatous Disease

  • Rare.

  • Thickened, redundant valve.

  • Sagging of the leaflet in diastole.


Physiologic pr

Physiologic PR

Physiologic PR

  • Normal Pulmonic valve

  • Normal Pulmonary artery

  • Normal Chamber dimension


Physiologic pr1

Physiologic PR

  • Normal Pulmonary pressure

  • PR Jet length < 1 cm

  • PR Jet duration – not holodiastolic


Borderline pr

Borderline PR

  • PR jet length 1 to 2 cm

  • PR duration - holodiastolic


Significant pr

Significant PR

  • PR Jet length > 2 cm

  • PR duration – holodiastolic


Pulmonic pressure

Pulmonic Pressure

  • SPAP

  • MPAP

  • PAEDP


Systolic pulmonary artery pressure

Systolic Pulmonary Artery Pressure

  • Equals to RVSP in the absence of RVOT obstruction

  • SPAP = 4 (TR peak velocity)2 + RAP

  • RAP estimated from IVC


Pulmonic regurgitation

TR – RVSP/SPAP


Mean pulmonary artery pressure

Mean Pulmonary Artery Pressure

MPAP mmHg = 80 – 0.5 x acceleration time (RVOT)

MPAP mmHg = 4(PR peak velocity)²

Acceleration Time

Acceleration time

Pulmonary Hypertension


Pulmonic regurgitation

Pulmonic Valve - PWD

MPAP = 80 – 0.5 x Acceleration Time

Normal MPAP = 9 to 18 mmHg

PR – Peak Velocity


Pulmonary artery end diastolic pressure

Pulmonary Artery End-Diastolic Pressure

PAEDP = 4 x (PR end-diastolic velocity)2 + RAP
