[Primary dissection of the left coronary artery with rupture of the ventricle in a 27-year-old patient].

This report of a 27-year-old patient describes an extensive infarction of the anterior wall due to primary dissection of the left coronary artery in the absence of the circumflex artery followed by rupture of the left ventricle. In earlier reports an aortocoronary bypass operation was usually performed in similar situations. Although the final outcome was lethal, this case report shows recanalization by methods of "interventional cardiology" to be a potentially successful alternative which may be of value when bypass operation is not available or contraindicated, as in developing cardiogenic shock. This case report demonstrates an initially successful treatment, which after a stable interval was followed by a lethal complication, namely, rupture of the ventricle due to hemorrhagic infarction.
