Article Synopsis
  • The study evaluates the performance of ultrathin drug-eluting stents (DES) versus thin-strut DES and drug-eluting balloons (DEB) in treating in-stent restenosis (ISR) in patients.
  • Results show that ultrathin DES significantly lowers the risk of adverse events, including cardiac death and need for revascularization, when compared to both thin-strut DES and DEBs after three years of follow-up.
  • Additionally, in patients with diffuse ISR, ultrathin DES outperformed thin-strut DES in reducing risks of target lesion revascularization (TLR) and target vessel revascularization (TVR).

Background: Rotational atherectomy (RA) is traditionally administered for patients with heavily calcified lesions and is thereby characterized by a high risk of the performed intervention. However, the prevalence characteristics of cardiac arrest are poorly studied in this group of patients. We aimed to evaluate the frequency and risk factors of cardiac arrest during percutaneous coronary interventions (PCI) performed with RA and preceding coronary angiography (CA).

: The rate of in-stent restenosis (ISR) is decreasing; however, it is still a challenge for contemporary invasive cardiologists. Therapeutic methods, including drug-eluting balloons (DEBs), intravascular lithotripsy, excimer laser coronary atherectomy, and imaging-guided percutaneous coronary intervention (PCI) with drug-eluting stents (DES), have been implemented. Patients with diabetes mellitus (DM) are burdened with a higher risk of ISR than the general population.

Article Synopsis
  • Intravascular ultrasound (IVUS) and optical coherence tomography (OCT) enhance outcomes in percutaneous coronary interventions (PCIs) for certain patients.
  • A study analyzed data from 6,522 rotational atherectomy (RA-PCI) procedures performed between 2014 and 2021 to assess whether IVUS or OCT improves successful revascularization rates.
  • Results indicated that using these imaging techniques led to a significantly higher likelihood of achieving optimal blood flow post-procedure (TIMI 3 flow), with IVUS and OCT increasing success rates by approximately 67% and 66%, respectively.

Article Synopsis
  • The study investigates long-term outcomes of patients with in-stent restenosis (ISR) and chronic coronary syndrome (CCS) who underwent PCI using drug-eluting stents (DES) versus drug-coated balloons (DCB).
  • Patients treated with DES had significantly lower rates of target lesion revascularization (TLR), target vessel revascularization (TVR), and device-oriented composite events (DOCE) compared to those treated with DCB.
  • Overall, the findings suggest that using DES is more effective than DCB for this patient group in reducing revascularization needs over a long-term follow-up period.

  • Radial artery access is often preferred in coronary interventions, but spasms can occur, causing pain and complications during the procedure.
  • In a study of 103 patients, the incidence of radial artery spasm was found to be 24.3%, with factors like female sex and failed puncture attempts increasing the risk, while hydrophilic sheaths seemed to prevent spasms.
  • Signs of arterial spasm were frequently observed in angiographies but did not always result in significant symptoms; tight narrowing at the sheath tip was a notable predictor of symptomatic spasm.

  • Low operator and institutional volume in percutaneous coronary interventions (PCI) can lead to worse outcomes for patients, prompting this study to assess the link between operator experience and procedural success in chronic total occlusion (CTO) cases.
  • The study analyzed data from nearly 15,000 CTO-PCIs performed between 2014 and 2020, finding that higher annual caseloads per operator correlated with better procedural success rates and fewer complications.
  • Results indicated that operators performing around 40 CTO cases annually had the best outcomes, suggesting that increasing experience could enhance the quality of treatments in PCI.

Background: Standard modifiable cardiovascular risk factors (SMuRFs) remain well-established elements of assessing cardiovascular risk scores. However, there is growing evidence that patients presented without known SMuRFs at admission demonstrate worse post-myocardial outcomes. The aim of the study was to assess the influence of the SMuRF status on short- and long-term mortality rates in patients with first-time ST-segment elevation myocardial infarction (STEMI).

Out-of-hospital cardiac arrest (OHCA) remains a leading cause of global mortality, while survivors are burdened with long-term neurological and cardiovascular complications. OHCA management at the hospital level remains challenging, due to heterogeneity of OHCA presentation, the critical status of OHCA patients reaching the return of spontaneous circulation (ROSC), and the demands of post ROSC treatment. The validity and optimal timing for coronary angiography is one important, yet not fully defined, component of OHCA management.
