Despite the improvement of outcomes after the introduction of bare metal and drug eluting stents for the treatment of CAD, certain type of patients have still an increased risk of stent failure. An alternative is represented by drug-eluting balloons (DEB). This innovation could give potential benefits in particular for the in-stent restenosis (ISR) and the de-novo lesions. In the first setting DEB have shown results superior to those with plain-balloon angioplasty and similar to those with first generation DES. Their performance seems to be more evident in BMS-ISR than in DES-ISR, showing a reliable effectiveness in those cases of recalcitrant ISR or when dual antiplatelet therapy is not indicated. In the context of de-novo lesions the use of DEB as unique strategy results more safe and feasible than a strategy with combined BMS implantation. The results are comparable to DES in lesions limited to small coronary vessels. Other particular scenarios, like bifurcations, acute myocardial infarction and diffuse disease, have been approached with DEB resulting in very heterogeneous outcomes. At present, given the high efficacy of last generation DESs, DEBs should be considered where clinical and angiographic conditions require the avoidance of stent implantation.
