ECHOCARDIOGRAPHIC ABNORMALITIES OF THE MITRAL VALVE ASSOCIATED WITH A LARGE PERICARDIAL EFFUSION

Features of mitral stenosis and systolic anterior motion of the mitral valve were observed on the echocardiogram of a patient with a large posterior pericardial effusion. The abnormal findings disappeared with resolution of the fluid. Because pericardial effusion may result in the echocardiographic alteration of cardiac structures, repeat study is necessary after the effusion has cleared.     

ARRHYTHMIA WITH MITRAL VALVE PROLAPSE: RESULTS OF ANNULOPLASTY IN TWO PATIENTS

The effectiveness of posterior annuloplasty in two patients who failed to respond to medical treatment for atrial and ventricular arrhythmias related to mitral valve prolapse (MVP) is reported. Although the etiology of arrhythmia in MVP remains mostly speculative, anatomic correction of prolapse or billowing of the mitral leaflets appears to reverse the anatomic and pathologic conditions that cause the arrhythmia.
