What is the diagnosis for a patient with normal mitral, tricuspid, and pulmonic valve structures, trivial regurgitation, and no stenosis, with a mitral valve area (MVA) of 3.6 cm², peak velocities of 1.2 m/s, 1.2 m/s, and 1.0 m/s, and mean gradients of 6 mmHg, 2 mmHg, and 2 mmHg for the respective valves?

From the Guidelines

The patient's echocardiogram results indicate normal cardiac valve function, and no intervention is required based on these findings. The mitral valve has a normal structure with a peak velocity of 1.2 m/s, peak gradient of 6 mmHg, and a valve area of 3.6 cm², which is within normal range 1. According to the guidelines on the management of valvular heart disease 1, the echocardiographic criteria for severe valve stenosis are not met, as the valve area is greater than 1.0 cm² and the mean gradient is less than 10 mmHg. There is only trivial mitral regurgitation, which is clinically insignificant.

The tricuspid valve also appears structurally normal with trivial regurgitation, and the inferior vena cava (IVC) caliber is 1.3 cm, suggesting normal right atrial pressure, confirmed by the measured RA pressure of 3 mmHg 1. The tricuspid regurgitation velocity is 1.2 m/s, indicating normal right ventricular systolic pressure. The pulmonic valve is structurally normal with a peak velocity of 1.0 m/s and peak gradient of 4 mmHg, which are within normal limits 1.

Key points to note from the echocardiogram results include:

  • Normal mitral valve structure and function with no evidence of stenosis or significant regurgitation
  • Normal tricuspid valve structure and function with no evidence of stenosis or significant regurgitation
  • Normal pulmonic valve structure and function with no evidence of stenosis or significant regurgitation
  • Normal right atrial pressure and right ventricular systolic pressure. Overall, this echocardiogram demonstrates normal cardiac valve structure and function without evidence of stenosis or significant regurgitation in any of the valves examined 1.

From the Research

Valve Structure and Function

  • The mitral valve has a normal structure with a peak velocity of 1.2 m/s and no stenosis, indicating proper function 2.
  • The tricuspid valve also has a normal structure with no stenosis, and trivial regurgitation, suggesting minimal dysfunction 3, 4.
  • The pulmonic valve has a normal structure with a peak velocity of 1.0 m/s and no stenosis, indicating normal function 3.

Valve Disease and Treatment

  • Valvular heart disease affects up to 7% of adults up to age 44 and up to 13% of individuals older than 75 years, with calcification and stiffening of the valve leaflets being a common cause of stenosis 2.
  • Tricuspid valve disease can be primary or secondary, with secondary disease being more common and often caused by left heart disease 4.
  • Treatment options for tricuspid valve disease include balloon valvuloplasty, surgical valve repair, and replacement, with annuloplasty valve repair being a preferred option 3.
  • Pulmonary valve disease is often congenital and can be treated with percutaneous valve replacement or surgery 3.

Diagnosis and Management

  • Echocardiography is the gold standard for diagnosing and grading the severity of valvular heart disease 5.
  • Patients with progressive valvular heart disease should be followed annually by cardiology, with imaging performed based on the severity of valvular dysfunction 5.
  • Surgery or intervention is recommended only when symptoms dictate or when changes in left ventricular function occur, and should be performed after discussion by a heart team 5.
