Mitral valve disease.

Area of Science:

• Cardiology
• Aviation Medicine
• Valvular Heart Disease

Background:

• Mitral stenosis is a progressive heart condition with risks of systemic embolus and atrial fibrillation.
• Significant mitral stenosis is incompatible with single-crew professional operations due to potential incapacitation.
• Careful supervision and assessment are crucial for pilots with valvular heart conditions.

Purpose of the Study:

• To define criteria for certifying pilots with mitral valve disease.
• To outline conditions under which mild mitral regurgitation may be compatible with full flying status.
• To establish guidelines for regular cardiological review in aviation personnel.

Main Methods:

• Review of clinical guidelines and case studies related to mitral valve disease in pilots.
• Echocardiography to assess left atrial and left ventricular dimensions.
• Long-term follow-up (≥1 year) to monitor disease progression.
• Exercise electrocardiography for functional assessment.

Main Results:

• Mild mitral regurgitation, with specific etiologies excluded and normal cardiac dimensions, may allow full certification.
• Absence of disease progression over at least one year is a key factor for certification.
• Regular cardiological review, including echocardiography and exercise ECG, is mandatory.

Conclusions:

• Strict criteria must be met for pilots with mitral stenosis or regurgitation to maintain full flying status.
• Deviations from guidelines may result in restricted flying status (multi-crew operations) or denial.
• Proactive cardiological management is essential for aviation safety in affected individuals.
