To the Editor, Microcatheters are essential tools to facilitate guidewire manipulation and exchange, thus enhancing the guidewire penetration force.1 The ReCross over-the-wire dual-lumen microcatheter (DLM) (IMDS, The Netherlands) is the latest evolution among DLM microcatheters. However, no data are available in the medical literature yet. From September 2020 through November 2020 a total of 8 patients undergoing percutaneous coronary intervention (PCI) of chronic total coronary occlusions (CTO) with the ReCross at 5 Italian high-volume PCI-capable centers were retrospectively identified. This study complied with the Declaration of Helsinki, and written informed consent was obtained from all participants. Case 1. A proximal right coronary artery CTO underwent antegrade approach using the ReCross microcatheter (IMDS, The Netherlands) as a first choice due to the presence of a bifurcation at distal cap level (figure 1). The antegrade wire escalation technique was used with an Ultimate Bros 3 guidewire (Asahi Intecc, Japan) followed by a Gaia Second guidewire (Asahi Intecc, Japan) that was able to cross the CTO body and reach the side branch (right ventricular branch) distal true lumen (figure 1B). The ReCross was advanced over the Gaia Second guidewire through the lesion close to the bifurcation; afterwards, another Gaia Second guidewire was advanced through the...
