New-generation drug-eluting stents (DESs) represent the standard of care for patients undergoing percutaneous coronary intervention (PCI). Recent iterations in DES technology have led to the development of newer stent platforms with a further reduction in strut thickness. This new DES class, known as ultrathin struts DESs, has struts thinner than 70 µm. The evidence base for these devices consists of observational data, large-scale meta-analyses, and randomized trials with long-term follow-up, which have been conducted to investigate the difference between ultrathin struts DESs and conventional new-generation DESs in a variety of clinical settings and lesion subsets. Ultrathin struts DESs may further improve the efficacy and safety profile of PCI by reducing the risk of target-lesion and target-vessel failures in comparison to new-generation DESs. In this article, we reviewed device characteristics and clinical data of the Orsiro (Biotronik, Bülach, Switzerland), Coroflex ISAR (B. Braun Melsungen, Germany), BioMime (Meril Life Sciences Pvt. Ltd., Gujarat, India), MiStent (MiCell Technologies, USA), and Supraflex (Sahajanand Medical Technologies, Surat, India) sirolimus-eluting stents.

Acute decompensation often represents the onset of symptoms associated with severe degenerative aortic stenosis (AS) and usually complicates the clinical course of the disease with a dismal impact on survival and quality of life. Several factors may derange the faint balance between left ventricular preload and afterload and precipitate the occurrence of symptoms and signs of acute heart failure (HF). A standardized approach for the management of this condition is currently lacking. Medical therapy finds very limited application in this setting, as drugs usually indicated for the control of acute HF might worsen hemodynamics in the presence of AS. Urgent aortic valve replacement is usually performed by transcatheter than surgical approach whereas, over the last decades, percutaneous balloon valvuloplasty gained renewed space as bridge to definitive therapy. This review focuses on the pathophysiological aspects of acute advanced AS and summarizes current evidence on its management.

Transcatheter aortic valve implantation (TAVI) is an increasingly popular treatment option for patients with severe aortic stenosis. Recent advancements in technology and imaging tools have significantly contributed to the success of TAVI procedures. Echocardiography plays a pivotal role in the evaluation of TAVI patients, both before and after the procedure. This review aims to provide an overview of the most recent technical advancements in echocardiography and their use in the follow-up of TAVI patients. In particular, the focus will be on the examination of the influence of TAVI on left and right ventricular function, which is frequently accompanied by other structural and functional alterations. Echocardiography has proven to be key also in detecting valve deterioration during extended follow-up. This review will provide valuable insights into the technical advancements in echocardiography and their role in the follow-up of TAVI patients.

Background Periprocedural myocardial infarction (MI) according to the Society for Cardiovascular Angiography and Interventions (SCAI) criteria has prognostic relevance among patients undergoing percutaneous coronary intervention (PCI). However, it is unclear whether the type of cardiac biomarker used for the diagnosis of periprocedural MI plays a role in terms of event frequency and outcomes. Objectives To compare the characteristics of SCAI periprocedural MI based on creatine kinase-myocardial band fraction (CK-MB) vs. high-sensitivity cardiac troponin (hs-cTn) in patients undergoing elective PCI. Methods Between 2017 and 2021, periprocedural MI was assessed in a prospective study. The primary clinical outcome of interest was all-cause death at 1-year follow-up. Results A total of 1010 patients undergoing elective PCI was included. SCAI periprocedural MI based on CK-MB vs. hs-cTnI occurred in 1.8% and 13.5% of patients, respectively. hs-cTnI periprocedural MI in the absence of concomitant CK-MB criteria was associated with lower rates of ancillary criteria, including angiographic, ECG, and cardiac imaging criteria. At 1-year follow-up, periprocedural MI defined by CK-MB (adjusted hazard ratio, HR, 4.27, 95% confidence intervals, CI, 1.23–14.8; p = 0.022) but not hs-cTnI (adjusted HR 2.04, 95%CI 0.94–4.45; p = 0.072) was associated with a higher risk of all-cause death. Hs-cTnI periprocedural MI was not predictive of death unless accompanied by CK-MB criteria (adjusted HR 4.64, 95%CI 1.32–16.31; p = 0.017). Conclusions In the setting of elective PCI, using hs-cTn instead of CK-MB resulted in a substantial increase in SCAI periprocedural MI events, which were not prognostically relevant in the absence of concurrent CK-MB elevations.
