Flail aortic valve leaflets: M-mode and two-dimensional echocardiographic manifestations

Area of Science:

• Cardiology
• Medical Imaging

Background:

• Flail aortic valve leaflets can lead to severe aortic insufficiency.
• Accurate noninvasive diagnosis is crucial for patient management.

Observation:

• M-mode and two-dimensional echocardiography (2-D echo) were used to study four patients with flail aortic valve leaflets.
• Specific echocardiographic findings like diastolic aortic valve flutter and left ventricular outflow tract (LVOT) echoes were observed.

Findings:

• Echocardiography accurately identified flail aortic leaflets in all patients.
• Distinguishing flail leaflets from vegetations was achieved by analyzing the hinge point of LVOT echoes.
• Severe aortic insufficiency was diagnosed in three patients based on mitral valve flutter and early closure.

Implications:

• Echocardiography offers an accurate, noninvasive method for diagnosing flail aortic leaflets.
• This diagnostic approach can potentially obviate the need for cardiac catheterization before surgery.
• Early and accurate diagnosis facilitates timely surgical intervention for aortic valve disease.
