Summary
Isolated mitral valve prolapse (MVP) with a systolic click is often benign, despite concerns about potential complications. This case highlights reassurance for patients with MVP and no significant cardiac issues, even after experiencing chest pain.
Area of Science:
- Cardiology
- Diagnostic Imaging
Background:
- Mitral valve prolapse (MVP) diagnosis has increased due to advanced cardiac ultrasound.
- Early reports focused on MVP complications, but the natural history of isolated cases is often benign.
Observation:
- A patient presented with nonanginal chest pain, diagnosed with silent mitral valve prolapse via echocardiography.
- Electrocardiogram incidentally revealed "athletic heart" findings.
- Stress electrocardiogram and thallium scintigraphy demonstrated excellent cardiorespiratory fitness and normal myocardial perfusion.
Findings:
- The natural history of isolated mitral valve prolapse, particularly the systolic click, is generally benign.
- Serious complications of MVP are more probable in patients with mitral regurgitation or ECG abnormalities.
Implications:
- Reassurance is crucial for patients diagnosed with MVP without significant associated cardiac conditions.
- This case supports the safety of high-level physical activity, like marathon running, for individuals with uncomplicated MVP.
