How to perform a successful drug-coated balloon angioplasty? Tips and tricks.

Drug-coated balloons (DCB) offer an excellent alternative to stents as the antiproliferative drugs are delivered via balloons and hence there is no permanent implant of metal or polymer. This rationale applies perfectly in in-stent restenosis (ISR) as we want to avoid another layer of metal in a previously failed stent. However, their use has also been extended to de novo lesions especially in patients and lesion subsets where stents are not ideal.

The evolution and revolution of drug coated balloons in coronary angioplasty: An up-to-date review of literature data.

European Society of Cardiology (ESC) guidelines gave class I A indication for use of DCB in in-stent restenosis. However, no indication exists for the usage of DCB in de novo lesions. Although the current generation DES offer excellent results, as we embark more complex lesions such as calcified lesion and chronic total occlusion, restenosis and stent thrombosis are higher and tend to increase within the years.

Cross-Priming Dendritic Cells Exacerbate Immunopathology After Ischemic Tissue Damage in the Heart.

Background: Ischemic heart disease is a leading cause of heart failure and despite advanced therapeutic options, morbidity and mortality rates remain high. Although acute inflammation in response to myocardial cell death has been extensively studied, subsequent adaptive immune activity and anti-heart autoimmunity may also contribute to the development of heart failure. After ischemic injury to the myocardium, dendritic cells (DC) respond to cardiomyocyte necrosis, present cardiac antigen to T cells, and potentially initiate a persistent autoimmune response against the heart.

Pelvic floor examination performed by medical students: a model to obtain consent.

Student-led clinical examinations, including pelvic floor examinations, are an integral part of clinical training and can be beneficial to both students and patients alike. However, our experience and previous literature catalog numerous obstacles in obtaining consent for student-led pelvic floor examinations. Although some of these factors may not be modifiable, it is evident that efforts can be made to overcome those that are.
