Most common congenital heart disease associated with Noonan Syndrome –
Pulmonary valvular stenosis (50–60%)
Atrial septal defects (10–25%)
Ventricular septal defects (5–20%)
Hypertrophic cardiomyopathy (12–35%)
Congenitally bicuspid pulmonary valves are associated most commonly with which of the following -
Bicuspid valve is found in as many as 90% of patients with tetralogy of Fallot, whereas it is rare in individuals with isolated valvar PS.
Noncongenital postoperative pulmonic valvular stenosis is seen in –
Ross procedure for aortic valve disease - transfer of the pulmonary valve to the aortic position with a homograft pulmonary valve placed in the pulmonary position.
These patients may develop non-congenital postoperative pulmonic valvular or main pulmonary artery (PA) stenosis due to an immune response in the homograft.
Commonest cause of pulmonary valve stenosis –
Most common cause of pulmonary valve stenosis is congenital heart disease
All of the following are TRUE regarding valvular PS EXCEPT -
Valvular PS auscultation reveals –
• Normal S1
• Widely split S2
• Soft and delayed P2
• Systolic crescendo-decrescendo ejection murmur in the left upper sternal border that increases with inspiration and radiates diffusely
Pulmonary valve stenosis : Which of the following is/are TRUE –
2.Pulmonary ejection click decreases with inspiration
3.Peak pulmonic valve gradients greater than 40 mm Hg should undergo intervention
Peak pulmonic valve gradients greater than 60 mm Hg or a mean of 40 mm Hg by echocardiography/Doppler should undergo intervention regardless of symptoms.
What % of the patients with tetralogy of Fallot have associated Peripheral pulmonary stenosis:
20 % of the patients with tetralogy of Fallot have associated Peripheral pulmonary stenosis
What is the treatment of choice for pulmonary valve stenosis in symptomatic domed valve patients –
PULMONARY VALVE STENOSIS - Percutaneous balloon valvuloplasty is highly successful in domed valve patients and is the treatment of choice.
All of the following are indicators of increased severity of PS in ejection murmur EXCEPT –
As the severity of PS increases, the ejection murmur increases in intensity, its duration prolongs, and its peak becomes more delayed.
Sinus of Valsalva aneurysms can cause Pulmonic Stenosis by –
Sinus of Valsalva aneurysms and aortic graft aneurysms are extracardiac entities that can cause PS by external compression.
