pulmonary regargitation

👏👏WHAT IS PULMONARY REGURGITATION (PR)?

👌👌 A leaky pulmonary valve allows blood to flow back into the heart chamber before it gets to the lungs for oxygen.

👏👏Causes
• Dilatation of pulmonary valve secondary to pulmonary hypertension.
• Secondary to mitral stenosis producing an early diastolic murmur (Graham Steel murmur).
• Rheumatic fever.
• Carcinoid syndrome.

👏👏Symptoms
• May be asymptomatic or symptoms of primary disease.
• Features of right-sided heart failure.

👏👏Signs
• Left parasternal lift.
• P2 may be soft.
• Early diastolic murmur in 3rd or 4th left intercostal space.

👏👏Investigations
• Chest X-ray.
• ECG.
• Echocardiogram.

💊Treatment
• Teatment of underlying cause.
• In severe regurgitation—valve replacement.
