Optical coherence tomography (OCT) has become the invasive imaging modality of choice for coronary stent assessment due to its unmatched spatial resolution. Neointimal calcification (NC) is a rare finding, observed in 5-10% of in-stent restenosis (ISR) neointima. The impact of NC on percutaneous coronary intervention of ISR is unknown. We therefore present the outcome of six unique cases of ISR and NC in which OCT was used to evaluate the impact of NC on the quality of stent-in-stent deployment for the treatment of ISR. This series demonstrates for the first time the impact of NC on stent expansion, a finding which might help guiding percutaneous coronary intervention for ISR with NC.

Importance: Drug-coated balloon (DCB) angioplasty has emerged as an alternative to drug-eluting stent (DES) implantation for percutaneous coronary intervention (PCI) in patients with coronary in-stent restenosis (ISR) as well as de novo coronary artery disease.
Observations: DCBs are balloons coated with antiproliferative agents and excipients, whose aim is to foster favorable vessel healing after appropriate lesion preparation. By providing homogeneous antiproliferative drug delivery in the absence of permanent foreign body implantation, DCBs offer multiple advantages over DES, including preservation of vessel anatomy and function and positive vessel remodeling.

Objective: This study aimed to analyze the safety and mid-term outcomes of a hybrid treatment method combining rotational atherectomy (RA) with drug-coated balloon (DCB) angioplasty in patients with femoropopliteal artery in-stent restenosis (ISR).
Methods: This single-center retrospective study enrolled patients from January 2018 to March 2022 who had femoropopliteal artery in-stent restenosis treated by RA and DCB. Preoperative demographics, operative details, and postoperative 12-month follow-up outcomes were analyzed statistically.

Patients with diabetes mellitus (DM) have an increased risk of in stent restenosis (ISR). Neovascularization (NV) is considered as a unique pathophysiology factor of ISR in diabetic patients. However, the restructuring patterns of in vivo human coronary NV and their relationship with ISR, especially in diabetic patients remain unclear.

BACKGROUND Dual antiplatelet therapy is the main treatment for cardiovascular diseases (CADs). In this study, we evaluated the efficacy and safety of aspirin combined with low-dose rivaroxaban in the secondary prevention of high-risk ischemic cardiovascular diseases. MATERIAL AND METHODS In total, 168 patients who were diagnosed with acute myocardial infarction or multiple vessel disease 1 year after percutaneous coronary intervention were divided into 2 groups: the aspirin group (aspirin as acetylsalicylic acid: 100 mg once daily) and the aspirin + rivaroxaban group (aspirin: 100 mg once daily, rivaroxaban: 2.

Background: Elevated lipoprotein(a) (Lp[a]) is a risk factor for first atherosclerotic thrombosis events, but the role of elevated Lp(a) in secondary prevention is controversial. This study aimed to retrospectively investigate the influence of elevated Lp(a) levels on the prognosis of patients with coronary artery disease.
Methods: The team collected and compared clinical information of patients hospitalized during percutaneous coronary intervention (PCI).
