Therapeutic application of ultrasound: Contrast-enhanced thrombolysis in acute ST-elevation myocardial infarction; the Sonolysis study

Abstract

Abstract Contrast enhancement by microbubble infusion has proven its applicability in the field of diagnostic ultrasound. Recent studies also indicate a therapeutic effect of the combined use of ultrasound and microbubbles. Results from animal studies demonstrate that diagnostic ultrasound in combination with intravenous microbubbles can dissolve thrombi. So far, this effect has never been tested in patients with an acute ST-elevation myocardial infarction (STEMI). We recently launched a pilot study in acute STEMI patients to assess safety, feasibility and efficacy of the treatment in this patient group with transthoracic three-dimensional diagnostic ultrasound and intravenous micro-bubbles immediately after prehospital thrombolysis, but prior to primary percutaneous coronary intervention. © The Author(s) 2011.
