[Ischemic left ventricular failure. Main stem coronary stenosis treated with angioplasty]

We describe a patient with stenosis on the left main stem and severe impairment of the left ventricular function. Because of reversible myocardial ischaemia in a patient whose clinical situation prohibited surgery, angioplasty on the left main stem was performed, leading to considerable improvement of the ventricular function. Improvement was slow, however, probably due to "stunning" of the myocardium. We underline the importance of early angiography in patients when it is suspected that a larger part of the myocardium is affected by severe, reversible ischaemia.
