Enhanced Efficiency of Sequential Cutting Balloon Angioplasty in Calcified Coronary Artery Disease: The RODIN-CUT Technique.
Catheter Cardiovasc Interv
January 2025
HartCentrum Ziekenhuis Aan de Stroom (ZAS) Middelheim, Antwerp, Belgium.
Article Synopsis
- Heavily calcified coronary artery disease complicates percutaneous coronary intervention (PCI), requiring advanced techniques like cutting balloons (CB), which need standardization for better effectiveness.
- The study presents the RODIN-CUT technique, which involves sequential CB inflations guided by intravascular ultrasound (IVUS) to improve plaque modification and stent expansion in difficult cases.
- Results indicate that RODIN-CUT achieved high procedural success rates and minimal complications, suggesting it could be a simple and cost-effective method for treating calcified lesions, though larger studies are needed to confirm its validity.
Intravascular Imaging-Guided Versus Angiography-Guided Percutaneous Coronary Intervention in Patients With ST-Segment Elevation Myocardial Infarction in the United States.
Catheter Cardiovasc Interv
December 2024
Cardiac Catheterization Laboratory of the Cardiovascular Institute, Mount Sinai Hospital, New York, New York, USA.
Background: The role of Intravascular ultrasound (IVUS) and optical coherence tomography (OCT) is still unclear in patients with STEMI undergoing PCI in the current second-generation DES era.
Aims: This study aimed to evaluate the trends and outcomes of IVUS-guided PCI in patients with STEMI.
Methods: We used the National Inpatient Sample (NIS) database from 2016 to 2021.
Fractional Flow Reserve Directed Percutaneous Coronary Intervention Optimization Using High-Definition Intravascular Ultrasound in Non-ST-Segment Elevation Acute Coronary Syndrome Versus Chronic Coronary Syndrome.
Catheter Cardiovasc Interv
December 2024
Department of (Interventional) Cardiology, Thoraxcenter, Erasmus University Medical Center, Rotterdam, the Netherlands.
Background: Intravascular ultrasound (IVUS)-guided optimization of suboptimal fractional flow reserve (FFR) following percutaneous coronary intervention (PCI) results in a significant increase in both post-PCI FFR and minimal lumen and stent areas (MLA and MSA, respectively). However, the impact of clinical presentation with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) versus chronic coronary syndrome (CCS) on the efficacy of PCI optimization remains unknown.
Methods: This was a prespecified subgroup analysis of the FFR REACT trial comparing IVUS-guided PCI optimization versus no further treatment in 291 patients with a post-PCI FFR < 0.
Successful Bailout of Catheter-Induced Dissection in Acute Myocardial Infarction Resulting From a Nondominant Right Coronary Artery Occlusion.

A 48-year-old male with a history of hyperlipidemia presented to the emergency department with chest pain. Electrocardiographic abnormalities indicated an acute coronary syndrome. Urgent coronary angiography revealed nondominant right coronary artery (RCA) occlusion.

Predicting coronary artery occlusion after transcatheter aortic valve replacement (TAVR) is usually based on computed tomography angiography (CTA). The primary risk factors seem to be a low coronary artery take-off and a small aortic root. However, CTA sometimes provides ambiguous risk assessment, and even if a potentially risky coronary artery is secured with a guidewire, the need for coronary stenting after valve implantation often remains uncertain.
