Mitral Valve Disease in Echo

listening to sound in the body

• Fatigue
• DOE
• Palpitations
• Severe orthopnea
• L and/or R Heart Failure

backwards flow of blood through the MV during systole (most common)

• No. But commonly referred to as.
• Regurg results from Insufficiency.

Intermittent; acute; chronic

• Prophylactic antibiotics
• Catheter balloon valvuloplasty
• Commissurotomy
• Mitral Valve Replacement

MV replacement

• Planimetry
• Pressure Half time
• Continuity Equation
• PISA

• trace valve orifice (opening) in PSAX.
• Must find smallest on-axis opening

Valve Area calculated by dividing measured PHT into 220 (constant).

Multiple because it gives a rough estimate of what their actual pressure values are during erratic streak.

No. Because the recent balloon inserted in their valve would show faulty values of what their body was actually producing.

• Spectral Wave Doppler of MV leaflet tips during dystole.
• the E-F descending slope, is then measured.

Calculation mitral valve Area

Calculating MV Area

• Proximal
• Isovelocity
• Surface
• Area

Not easily reproducible by sonographers

stipulates that unobstructed flow convergence equates to concentric acceleration. Shows acceleration at different points in time

• 1. A4C - Zoom MV
• 2. Apply Color doppler
• 3. Shift of zero baseline upward (Nyquist Limit)
• 4. Save to Cine loop
• 5. Freeze best frame to measure radius of MR in LA
