Prospective Multicenter Study to Characterize the REAL-WORLD EVIDENCE Regarding Safety and Performance of the PTCA Catheters Family

Start date: July 29, 2022
Phase:
Study type: Observational

The purpose of this Post market Study is to collect clinical data of the Arthesys PTCA catheters family during angioplasty intervention of coronary vessels or coronary bypass graft stenosis to support MDR submission.

NCT ID: NCT04985773 Completed - Coronary Stenosis Clinical Trials

A Study to EXhibit Percutaneous Coronary Artery Dilatation With Non-Slip Element Balloon

EXPANSE-PTCA
Start date: December 17, 2021
Phase: N/A
Study type: Interventional

The objective of this study is to evaluate safety and effectiveness of the Lacrosse NSE ALPHA coronary dilatation catheter during PCI in subjects with stenotic coronary arteries.

NCT ID: NCT04984135 Completed - Coronary Stenosis Clinical Trials

DCB Angioplasty for Coronary Lesions: an OCT Analysis

Start date: December 1, 2020
Phase:
Study type: Observational [Patient Registry]

In this study, the investigators preformed OCT before and after DCB treatment, as well as at 6 months of follow-up, to assess the tissue characterization. The aim of this study was to investigate the relationship between quantitative and qualitative OCT findings, angiographic and clinical outcomes after PCB for coronary lesions.

NCT ID: NCT04975425 Completed - Clinical trials for Coronary Artery Disease

Effects of Guiding Catheter on FFR and NHPR for the Assessment of Coronary Artery Stenoses (Disengage@Rest)

Disengage@Rest
Start date: July 1, 2021
Phase:
Study type: Observational

The DISENGAGE@rest study is a prospective registry carried out at Federico II University of Naples with the aim to evaluate the influence of the guiding catheter engagement within the coronary ostium on both FFR and non-hyperaemic pressure ratios values (such as Pd/Pa and the Resting Full-cycle Ratio -RFR), as well as the corresponding clinical impact on decision-making strategies. Consecutive patients with at least one intermediate stenosis (40%-90% by visual estimation) in any of the 3 main coronary arteries will be included.

NCT ID: NCT04970082 Completed - Clinical trials for Coronary Artery Stenosis

A Study to Evaluate Direct Wire Pacing (DWP) for Measuring Fractional Flow Reserve (FFR)

Start date: June 17, 2021
Phase: N/A
Study type: Interventional

This is a randomized, non-inferiority, crossover investigation comparing the Direct Wire Pacing (DWP) versus standard method to measure Fractional Flow Reserve (FFR) in subjects with FFR indications. All subjects requiring on a clinical basis a pressure wire assessment of coronary artery stenosis(es) will be eligible to take part in the study.

NCT ID: NCT04862689 Completed - Coronary Stenosis Clinical Trials

Investigation of the Ringer Perfusion Balloon Catheter (Ringer PTCA)

Start date: May 1, 2022
Phase: N/A
Study type: Interventional

The objective of this study is to demonstrate safe and effective use of the Ringer perfusion balloon catheter for dilatation/pre-dilatation of coronary stenoses during percutaneous coronary intervention (PCI).

NCT ID: NCT04761939 Completed - Clinical trials for Cardiovascular Diseases

BIONICS Small Vessels Trial EluNIR Ridaforolimus Eluting Coronary Stent System (EluNIR) In Coronary Stenosis Trial

Start date: December 31, 2020
Phase:
Study type: Observational

Device: EluNIR Ridaforolimus Eluting Coronary Stent System - (hereafter referred to as EluNIR) 2.25 mm diameter (8 mm, 12 mm, 15 mm, 17 mm, 20 mm, 24 mm, 28 mm and 33 mm length) Objectives: To further assess the safety and efficacy of the small diameter (2.25 mm) Ridaforolimus Eluting Stent - EluNIR. Subject Population: Subjects who underwent PCI for angina (stable or unstable), silent ischemia (in absence of symptoms a visually estimated target lesion diameter stenosis of ≥70%, a positive non-invasive stress test, or FFR ≤0.80 must be present), NSTEMI, and recent STEMI (>24 hours from initial presentation and stable) with attempted implantation of a 2.25 mm diameter EluNIR stent. Trial Design and Methods: This is a prospective, multi-center, single-arm, open-label clinical trial. Clinical follow-up for all patients will be performed at 30 days 6 months, and 1 year after the procedure.

NCT ID: NCT04680689 Completed - Myocardial Ischemia Clinical Trials

Assessment of Lesion-Associated Myocardial Ischemia Based on Fusion Coronary CT Imaging

FUSE-HEART
Start date: July 30, 2021
Phase:
Study type: Observational

The aim of the Fused-Heart study is to investigate the impact of a coronary artery stenosis on myocardial function and viability, based on advanced fusion imaging techniques derived from CCTA. Moreover the study will investigate the correlation between morphology and composition of atheromatous plaques located in a coronary artery and myocardial ischemia in the territory irrigated by the same coronary artery.

NCT ID: NCT04397198 Completed - Clinical trials for Acute Myocardial Infarction

The Assessment Of Myocardial Viability Based On CTA/MRI Hybrid Models

HYBRIDHEART
Start date: July 6, 2020
Phase:
Study type: Observational

The aim of HYBRIDHEART study is to develop new imagistic prototype for a complex evaluation of the myocardial viability by superposing computed tomographic angiographic polar maps of the myocardium with magnetic resonance imaging contractile maps in subjects who suffered an acute myocardial infarction. Moreover, the study will evaluate the association of myocardial viability with the level of inflammatory markers and the percent of myocardial fibrosis, also will correlate the imaging-derived parameters with the inflammatory status of the patients, left ventricular function, ischemic time and major adverse cardiovascular events (MACE) rate.

NCT ID: NCT04356027 Completed - Clinical trials for Coronary Artery Disease

FUnctional diagnoSIs of corONary Stenosis (FUSION)

FUSION
Start date: June 26, 2020
Phase:
Study type: Observational

The purpose of the FUSION study is to validate the diagnostic performance of Virtual Flow Reserve (VFR) by comparing it against a reference standard, fractional flow reserve (FFR).
