Duration of DAPT in ACS: The DUAL-ACS Trial

31 Aug 2025

Ali Nazmi Calik interviews David Newby on the landmark DUAL-ACS trial results he presented at ESC Congress 2025 in Madrid.

The trial compared 3 months versus 12 months of dual antiplatelet therapy (DAPT) after myocardial infarction in an all-comer population. Findings suggest that shorter therapy may offer better...

Comparison of stent geometry achieved by different side-branch ballooning techniques for bifurcation provisional stenting: the CRABBIS Trial

31 Mar 2025

Which ballooning technique is best after main vessel stenting in bifurcation PCI? This two-part study compares two key approaches: PKP (POT, kissing balloon inflation, final POT) and PSP (POT, isolated side branch dilation, final POT) to determine the optimal strategy.

Rotational atherectomy, lithotripsy, or laser for calcified coronary stenosis: the ROLLER COASTR-EPIC22 trial

24 Mar 2025

Due to a lack of randomised evidence, this randomised controlled trial (RCT) aimed to compare the safety and efficacy of IVL and ELCA with RA in treating heavily calcified coronary lesions before drug-eluting stent implantation.

Usefulness of FFR-CT to exclude haemodynamically significant lesions in high-risk NSTE-ACS

07 Mar 2025

This single-arm, double-blinded, core-laboratory adjudicated, prospective trial, conducted across four European centers between August 2019 and April 2022, investigates whether CCTA and FFR-CT are able to exclude hemodynamically significant coronary stenoses in patients with high-risk NSTE-ACS.

Complex non left main bifurcation PCI - LIVE case

19 Dec 2024 – From GulfPCR-GIM 2024

A 71-year-old male presented with angina (CCS 2), normal left ventricular function, and mitral stenosis. Coronary angiography revealed severe ostial stenosis of the circumflex artery and a significant LAD/diagonal bifurcation lesion (Medina 0.1.1).

The operators performed balloon valvuloplasty to treat the mitral stenosis, followed by LAD/diagonal PCI....

Ultrasound-guided versus fluoroscopy-guided large-bore femoral access in PCI of complex coronary lesions: the international, multicentre, randomised ULTRACOLOR Trial

02 Dec 2024

Compared to fluoroscopy guidance, routine use of ultrasound for large-bore transfemoral access in complex PCI did not significantly reduce clinically relevant bleeding or vascular complications. However, it notably improved first-pass puncture success, with a very low crossover rate.

Effective techniques for performing DCB angioplasty

16 Jan 2025

Drug-coated balloon (DCB) angioplasty has become a valuable alternative to drug-eluting stents in treating coronary artery disease. To achieve optimal outcomes, proper lesion preparation and techniques to minimise drug loss are crucial.

This article highlights key steps and best practices for performing DCB angioplasty, ensuring effective drug delivery and...

Immediate versus staged complete revascularisation in patients presenting with STEMI and multivessel disease

21 Oct 2024

The current subanalysis of the BioVasc trial offers valuable insights into the long-term effects of ICR versus SCR strategies in STEMI patients with MVD. The findings support current guidelines on the necessity of revascularizing non-culprit lesions.

Percutaneous coronary intervention for bifurcation coronary lesions using optimised angiographic guidance: the 18th Consensus Document from the European Bifurcation Club

24 Jun 2024

In coronary bifurcation lesions (CBL) PCI, intracoronary imaging (ICI) is preferred for its superior outcomes over angiography alone, but its adoption is limited by education and technology access barriers, resulting in most CBL PCIs still using angiographic guidance only.
