Clinical and Angiographic Outcomes of Post-drug-coated Balloon Angioplasty in Native Coronary Lesions

In recent years, drug-coated balloon (DCB) therapy has been rapidly accepted in clinical practice, especially for the treatment of in-stent restenosis. More recently, the use of DCB is spreading to de novo CAD. The DCB has beneficial features, such as allowing local drug delivery without the need to implant any metal. Subsequently, the duration of dual antiplatelet therapy (DAPT) is shortened. Importantly, the DCB is just a delivery vehicle, and does not assist in dilating narrowed coronary vessels. Thus, lesion preparation with standard balloon angioplasty is the key to successful DCB treatment, and is essential before the use of a DCB. The aim of effective lesion preparation is to gain sufficient luminal enlargement, while minimizing coronary dissection. As DCBs are fulfilling the concept of "leaving nothing behind" and guidelines are also recommended as class I indication the use of DCBs have become an alternative therapeutic option for the treatment of ISR \& small de novo vessel. Till to date no such type of study conducted in Bangladesh. That's why the investigators designed this study with the aim to observe clinical and angiographic outcomes of drug-coated balloon angioplasty after successful revascularization of native coronary lesions among Bangladeshi population which is very essential and relevant in the context of Bangladesh.
