NCT ID: NCT06252350 Completed - Clinical trials for Coronary Artery Disease

CERROS Pilot Study

CERROS - Pilot
Start date: February 22, 2024
Phase:
Study type: Observational

The primary objective of this study is to determine whether a reduced radiation protocol (RRP) in which angiograms are acquired at ultralow radiation doses and then processed using spatiotemporal enhancement software can produce similar quality angiographic images as compared with standard techniques.

NCT ID: NCT05998252 Completed - Clinical trials for Coronary Artery Disease

Evaluate Safety and Efficacy of Alveo HP Balloon Dilatation Catheter for Balloon Dilatation of Coronary Artery Stenosis

Start date: December 27, 2022
Phase: N/A
Study type: Interventional

This is a prospective, multi-center, single-group study aims to evaluate the safety and efficacy of Alveo HP Balloon Dilatation Catheter for balloon dilatation of coronary artery stenosis. Pre-dilation with Alveo balloon dilatation catheter followed by conventional PCI, and follow-up will be carried out. During the trial, the enrollment, treatment and follow-up of the subjects will be recorded, and the safety and efficacy of the investigational device will be evaluated.

NCT ID: NCT05836467 Completed - Clinical trials for Coronary Artery Disease

Is Myocardial Revascularization Really Necessary in Patients With ≥50-70% Coronary Stenosis Undergoing Valvular Surgery?

Start date: October 5, 2019
Phase:
Study type: Observational

It is well documented in the literature that myocardial revascularization during valve surgery increases the risk of early mortality and morbidity. According to the most recent version of the European Guidelines, the possibility of myocardial revascularization via coronary artery bypass should be evaluated in patients with an indication for surgical treatment of heart valve disease but with coronary artery stenosis ≥ 50-70%. In this study, patients hospitalized for surgical heart valve disease, with occasional pre-operative finding of ≥ 50-70% coronary artery stenosis, without angina, are examined. After interdisciplinary discussion in the Heart Team, it was decided not to treat coronary artery disease during valve surgery. The aim is to evaluate the short and medium-term results of this "conscious omission".

NCT ID: NCT05804500 Completed - Clinical trials for Coronary Artery Disease

RecoveryPlus Telerehab Platform Pilot Study

Start date: March 27, 2023
Phase: N/A
Study type: Interventional

In this prospective, single-arm study, we will look at the initiation, participation, sustained engagement, and safety of 100 adult subjects (ages 45 years or older) with recent (within the past 60 days) clinician referral to CR who are offered CTR via the RecoveryPlus platform. We want to understand the effectiveness of the RecoveryPlus platform in engaging participants in CR while remaining a safe alternative for the delivery of evidence-based CR content. The primary hypothesis of this study is that the RecoveryPlus CTR platform and patient-facing mobile application provide a safe alternative to traditional in-person CR, and demonstrate a high rate of initiation, participation, and engagement in CR exercise programming than traditional modes of CR delivery, as documented in the literature. Current in-person and non-personalized CR programming lacks RecoveryPlus' convenient remote access, easy-to-use digital tools to support independent, autonomous exercise, and a platform to facilitate engagement and feedback between patients and EPs.

NCT ID: NCT05536180 Completed - Clinical trials for Coronary Artery Stenosis

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

Start date: March 6, 2023
Phase:
Study type: Observational

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

NCT ID: NCT05509296 Completed - Coronary Stenosis Clinical Trials

Compare the Effectiveness and Safety of Two Different Kinds of Cutting Balloon in Coronary Artery Disease

Start date: September 20, 2022
Phase: N/A
Study type: Interventional

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

NCT ID: NCT05421169 Completed - Clinical trials for Coronary Artery Disease

Diastolic Hyperemia-Free Ratio in Patients With CAD

ICE-HEAT
Start date: August 23, 2022
Phase:
Study type: Observational [Patient Registry]

The investigators aimed to identify the value of concordance between the diastolic hyperemia-free ratio (DFR) and fractional flow reserve (FFR) during pre-interventional and post-interventional period using a 0.014" COMET II Pressure Guidewire

NCT ID: NCT05251012 Completed - Clinical trials for Coronary Artery Disease

3D-QFR in Non-selected Angiographic Stenosis. A Spanish Multicentre Study.

Start date: January 1, 2015
Phase:
Study type: Observational

Physiology-based decision-making about the need for revascularisation in patients with stable coronary heart disease has consistently proven better clinical outcomes than a merely anatomical approach. However, against the current recommendations, revascularisation in most of patients with chronic coronary syndromes still relies on coronary angiography alone. The increase in costs and in procedural complexity of wire-based physiology may explain the latter. Therefore, a novel non-invasive functional quantitative flow ratio (QFR) index was created in order to solve it. A retrospective and multicentre study is performed to assess the 5-year prognosis of patients undergoing coronary angiography through a centralized QFR analysis. Consecutive participants with confirmed or suspected diagnosis of stable coronary disease who underwent a coronary angiography between 01/01/2015 and 12/31/2015 were included. Aims of the study: - To evaluate the prognosis of stable coronary disease depending on the functional assessment of coronary artery disease. - To determine the % of percutaneous coronary interventions that could be avoided if this study had been carried out through functional assessment of coronary artery disease based on 3-dimensional vessel reconstruction.
