Feasibility and Safety of the ETcath200 Robotic PCI System for Complex Coronary Lesions: A Prospective Single‐Center Study

open access: yesCatheterization and Cardiovascular Interventions, Volume 107, Issue 5, Page 1393-1402, April 1, 2026.
ABSTRACT Background International robotic‐assisted PCI platforms such as CorPath 200 and CorPath GRX have demonstrated procedural safety and efficacy but are limited by the absence of real‐time tactile feedback and cumbersome device exchange. The ETcath200, the first domestically developed robotic PCI system in China, introduces guidewire force‐sensing

Coronary flow velocity reserve after percutaneous interventions is predictive of periprocedural outcome [PDF]

open access: yes, 2002
BACKGROUND: Because heterogeneous results have been reported, we assessed coronary flow velocity changes in individuals who underwent percutaneous transluminal coronary angioplasty (PTCA) and examined their impact on clinical outcome. METHODS AND RESULTS:

Stent Thrombosis: A Narrative Review From Pathophysiology to Therapy

open access: yesClinical Cardiology, Volume 49, Issue 4, April 2026.
Stent thrombosis remains a life‐threatening complication of PCI driven by complex interactions between stent design, procedural factors, thrombogenic milieu, and inflammation. This review integrates pathophysiological mechanisms with contemporary and emerging therapeutic strategies, highlighting optimized PCI, tailored antithrombotic therapy, and novel

Randomized comparison of primary stenting and provisional balloon angioplasty guided by flow velocity measurement. [PDF]

open access: yes, 2000
BACKGROUND: Coronary stenting improves outcomes compared with balloon angioplasty, but it is costly and may have other disadvantages. Limiting stent use to patients with a suboptimal result after angioplasty (provisional angioplasty) may be as effective ...

Prognostic Implication of CYP2C19 Genotype According to Clinical Risk Stratification After Drug‐Eluting Stent Implantation

open access: yesClinical Pharmacology &Therapeutics, Volume 119, Issue 4, Page 928-941, April 2026.
From the nationwide multicenter consortium, 8,163 patients undergoing drug‐eluting stent implantation were classified according to the presence of the CYP2C19 loss‐of‐function (LoF) allele: rapid or normal metabolizers (RMs/NMs) vs. intermediate or poor metabolizers (IMs/PMs), and clinical risk was stratified using the CHADS‐P2A2RC and TRS 2°P scores ...

Three dimensional intravascular ultrasonic assessment of the local mechanism of restenosis after balloon angioplasty [PDF]

open access: yes, 2001
OBJECTIVE: To assess the mechanism of restenosis after balloon angioplasty. DESIGN: Prospective study. PATIENTS: 13 patients treated with balloon angioplasty. INTERVENTIONS: 111 coronary subsegments (2 mm each) were analysed after balloon angioplasty and

Numerical Investigation of a Dual‐Mode Shape Memory Alloy Stent Enabling Secondary Expansion via Focused Ultrasound: A Potential Strategy for Correcting In‐Stent Restenosis

open access: yesAdvanced Engineering Materials, Volume 28, Issue 6, 18 March 2026.
This study demonstrates a novel noninvasive strategy to treat in‐stent restenosis using focused ultrasound. A shape memory alloy stent initially expands at body temperature. If restenosis occurs, targeted ultrasound heating thermally actuates the stent, enabling a secondary expansion to reopen the blocked vessel, offering a potential alternative to ...

ST‐Segment Elevation Myocardial Infarction With Right Coronary Aneurysm Successfully Treated With a Drug‐Coated Balloon‐Only Strategy

open access: yesClinical Case Reports
ST‐segment elevation myocardial infarction (STEMI) with a coronary aneurysm is rare; therefore, its treatment approach remains not well established.
