Randomized and observational studies have been shown that coronary intervention with drug-coated balloons (DCB) provide a promising alternative to DES implantation in small vessels, while avoiding the risk of a permanent vascular implant. Furthermore, lesions in small vessels are frequently concomitant with diffuse disease and\u002For distal location, where the presence of calcification is an additional common feature. Intravascular lithotripsy (IVL) has been recently introduced as a novel adjunctive technology to treat calcified lesions.\n\nThis study will explore the hypothesis that IVL has the potential to enhance the results of coronary balloon dilatation of small vessels with calcified lesions, therefore increasing the likelihood of optimal DBC intervention.",[24],"Calcified Lesions in Small Coronary Vessels","RECRUITING","2025-05-13",{"date":28,"type":29},"2025-05-16","ACTUAL",{"date":31,"type":29},"2023-06-16",{"date":33,"type":20},"2026-06-30",{"name":35,"class":36},"Rede Optimus Hospitalar SA","NETWORK",2]
