[Intracoronary ultrasound: the "platinum standard" in evaluating the morphology of coronary stenoses. Does it have a role in clinical practice?].

: The authors present the case of a 45-year-old man with a history of myocardial infarction of the anterior wall and unstable angina pectoris where they detected a critical stenosis of the proximal segment of the ramus, interverticularis anterior by intracoronary ultrasound examination. The subsequent coronary angioplasty with implantation of a stent was also implemented under ultrasound control. The authors discuss the contemporary position of intravascular ultrasound in coronary interventions in particular with regard to the development of restenosis.
