Background: Transfemoral access is often used when large-bore guide catheters are required for percutaneous coronary intervention (PCI) of complex coronary lesions, especially when large-bore transradial access is contraindicated. Whether the risk of access site complications for these procedures may be reduced by ultrasound-guided puncture is unclear.
Aims: We aimed to show the superiority of ultrasound-guided femoral puncture compared to fluoroscopy-guided access in large-bore complex PCI with regard to access site-related Bleeding Academic Research Consortium 2, 3 or 5 bleeding and/or vascular complications requiring intervention during hospitalisation.
Background: Recurrent in-stent restenosis (ISR) remains a serious problem. Optimal modification of the underlying mechanism during index percutaneous coronary intervention (PCI) is key to prevent ISR. Excimer laser coronary atherectomy (ELCA) has its own indications and is among others used in recurrent ISR in case of stent underexpansion and/or diffuse neointimal hyperplasia.

We recently showed that the Silverway guidewire was effective at delivering the catheter to the aortic root. In this study, we aimed to compare the efficacy and safety of Radifocus and Silverway guidewires in 100 patients after failed use of the J-tip guidewire.

Case Summary: We describe a case of a 56-year-old female with a past medical history of spontaneous dissection of the distal descending left artery (LAD) 6 years before.
Background: The postdischarge prognostic implication of periprocedural myocardial injury in patients undergoing percutaneous coronary intervention (PCI) of a chronic total occlusion (CTO) remains scarcely studied.
Aims: The aim of this study is to assess the prognostic value of periprocedural myocardial injury, defined by increased high-sensitive troponin T (hs-TnT) levels according to updated guidelines, after CTO PCI.
Methods: Between September 2011 and April 2020, 726 patients undergoing CTO PCI at 2 Belgian referral centres were prospectively included and divided into 4 groups based on postprocedural hs-TnT levels (unelevated; ≥5 times the upper limit of normal (ULN); ≥35 times the ULN; ≥70 times the ULN).
Article Synopsis
- This study aimed to compare two types of mechanical circulatory support (MCS) systems, Impella CP and VA-ECMO, in patients undergoing complex high-risk PCI procedures.
- Researchers analyzed data from 41 patients who could not undergo surgery, with no significant differences found in hemodynamic stability or major adverse cardiac events between the two groups.
- The findings suggest that the choice between Impella CP and VA-ECMO does not significantly impact patient outcomes, including mortality rates.
Article Synopsis
- Patients with complex coronary artery disease who are not candidates for traditional surgery may benefit from high-risk percutaneous coronary intervention (PCI) using the Impella CP device for improved outcomes.
- A study involving 27 high-risk patients showed a 30-day mortality rate of 7.4% and a complication rate of 37% for major adverse cardiac events (MACE), indicating notable risks but feasible results.
- The Impella CP provided effective hemodynamic support without significant kidney function decline during the procedure, suggesting it is a viable option for this difficult patient population.
