REVERSIBLE SEVERE MITRAL REGURGITATION PROVOKED BY REVERSIBLE MYOCARDIAL-ISCHEMIA - ABOLITION BY CORONARY-ARTERY STENTING

Severe acute mitral regurgitation (MR)can occur with ruptured whole pa pillary muscle or isolated heads of papillary muscles or chordae tendi nae during the course of myocardial infarction.(1,2) 2 Furthermore MR may be precipitated by impaired function of non-ruptured papillary mus cle after myocardial infarction.(3) We report an unusual case of trans ient severe MII, as evidenced by transient giant 'V' waves in the dire ct left atrial pressure (LA) tracing during angina pectoris.
