Classification

Valvular heart diseases are typically classified according to the valve that is affected as well as the nature of the pathological defect as follows:

• Aortic Valve
  • Aortic stenosis
  • Aortic regurgitation
• Mitral Valve
  • Mitral stenosis
  • Mitral regurgitation
  • Mitral valve prolapse
• Tricuspid valve
  • Tricuspid stenosis
  • Tricuspid regurgitation
• Pulmonary valve
  • Pulmonic stenosis
  • Pulmonic regurgitation

Differential Diagnosis

Clinicians may differentiate among different valvular heart diseases on the basis of the characteristics of the murmur and collecting a thorough patient history, as shown in the following table:

Valvular Disease	Common causes	Murmur Description
		Low/High Frequency	Systolic/Diastolic Murmur	Best Heard Location	Other Features
Aortic stenosis	Senile calcification Calcification of bicuspid valve Other causes
Aortic regurgitation	Calcification of bicuspid valve Other causes
Mitral stenosis	Calcification of bicuspid valve Other causes
Mitral regurgitation	Calcification of bicuspid valve Other causes
Mitral valve prolapse	Calcification of bicuspid valve Other causes				Mid-systolic click
Tricuspid stenosis	Carcinoid heart disease Cardiac tumors Other causes	Low	Diastolic	Lower Left Sternal Border
Tricuspid regurgitation	Pulmonary hypertension Right ventricular failure Iatrogenic Carcinoid heart disease Other causes	Low	Pansystolic	Mid Sternal Border
Pulmonary stenosis	Congenital Rubella Syndrome Tetralogy of Fallot Carcinoid heart disease Other causes
Pulmonary regurgitation	Calcification of bicuspid valve Other causes
