Clinical Features
| Pulse | normal |
| Cardiac impulse | normal |
| Auscultation | Midsystolic click a high pitched sound caused by sudden tensing of the Mitral Valve apparatus as the leaflets prolapse |
| ECG | Most cases no abnormality |
| CXR | No abnormality unless significant MR |
Although most patients are asymptomatic, a wide variety of symptoms have been associated with MVP such as chest pain, breathlessness and palpitations. MVP may progress to clinically significant MR and there is an increased risk of infective endocarditis and cerebrovascular events. Men, those aged >45 and patients with significant MR are at high risk for complications. The association with sudden death is uncertain and is usually in the high risk group. Some patients have been noted to have long QT intervals. The clinical features, ECG and CXR findings are shown in Table 1.
