New Ultrasound-Controlled Paclitaxel Releasing Balloon vs. Asymmetric Drug-Eluting Stent in Primary ST-Segment Elevation Myocardial Infarction - A Prospective Randomized Trial.

Background: Application of drug-coated balloons (DCBs) is popular for the treatment of percutaneous coronary intervention (PCI). A new DCB has been designed as ultrasound-controlled paclitaxel releasing. This study was conducted to determine whether a DCB-only strategy has a similar safety profile and equal angiographic and clinical outcomes to DES implantation in primary ST-elevation myocardial infarction (STEMI) patients, as well as determine the efficiency and safety of this new DCB.
