- Abstract:
- It has been suggested that systolic bulging of the mitral valve caused by ischaemia induced left ventricular dysfunction may ultimately lead to mitral valve prolapse, making coronary heart disease the most important cause of secondary mitral valve prolapse. The influence of coronary heart disease on systolic displacement of the mitral valve was assessed in 90 consecutive patients with chest pain who were evaluated with coronary angiography and ventriculography of the left ventricle. 22 patients had coronary heart disease affecting one vessel (one vessel disease, OVD), 35 patients had coronary heart disease affecting more than one vessel (multiple vessel disease, MVD), and 33 patients had normal coronary arteries. The prevalence of mitral valve bulging was also determined in 16 patients with dilatative cardiomyopathy (CMP). Prevalence of mitral valve bulging in patients with OVD was not significantly different from normal patients. Patients with MVD and CMP had a lower prevalence of mitral valve bulging than normal patients and patients with OVD (p < 0.001). When all patients were grouped according to their ejection fraction, regardless of their underlying disease, there was a positive correlation between prevalence of mitral valve bulging and ejection fraction (r = 0.98, p < 0.001). Patients with an ejection fraction of below 50% did not have mitral valve bulging. We conclude that coronary heart disease is not a cause of mitral valve bulging and, furthermore, that systolic mitral valve bulging may serve as indicator of good left ventricular contractile function.
