This is a prospective, multicenter, randomized controlled clinical investigation aiming to evaluate the safety and effectiveness of non-slip balloon catheter for the treatment of patients with coronary artery stenosis.
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.
A randomize controlled trial will be conducted at Punjab institute of cardiology hospital Lahore, through convenience sampling technique on 48 patients which will be allocated through simple random sampling through sealed opaque enveloped into group A and Group B. Pretreatment values of patients' blood pressure, RR, HR, will be recorded. And patient's perception of illness through Illness Perception Questionnaire (IPQ), PHQ9 for depression assessment and HRQOL for quality of life will be assessed before and after treatment. Group A will be treated with basic Phase-I cardiac rehabilitation. And Group B will be treated with basic Phase-I cardiac rehabilitation along with Mindfulness based therapy. Treatment evaluation will be done after 8 weeks. Data will be analyzed using SPSS software version 25. After assessing normality of data by Shapiro-Wilk test, it will be decided either parametric or non-parametric test will be use within a group or between two groups.
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.
Ischaemic Heart Disease (IHD) is the worlds leading cause of death. IHD is often caused by a narrowing of the coronary arteries, which prevents blood from flowing to the heart muscle, causing pain and damage to the heart. If an individual has a myocardial infarction (MI), parts of the heart that are damaged cannot be repaired. Therefore, it is important to identify and treat the narrowing of the arteries before an MI occurs. At present there are 2 main methods of identifying narrowing of the arteries. The first is an invasive procedure, the other using a CT scan. Whilst both methods are effective, they entail risk. The invasive procedure can damage the coronary arteries, whilst the CT scan exposes patients to radiation and contrast, which can increase the risk of cancer and allergic reactions. Magnetic Resonance (MR) scanning is an alternative to these methods, but it has been limited in use in the past due, in part, to the high technical knowledge required to obtain images. In addition, there is a degree of subjectivity in the selection of the mid-diastolic rest period, potentially affecting consistency of results. This means it is difficult to use in a day-to-day hospital environment. However, recent technological developments using artificial intelligence mean that images can be acquired in a more automated and consistent fashion. This new scan has yet to be tested in a clinical trial. Therefore, the objective of the clinical study is to test this new scan to determine its efficacy. 230 patients at 5 sites at risk of coronary artery disease, who have been referred for invasive coronary angiography, will undergo both their angiography and the new MR scan. The MR scan will then be compared to CCTA for diagnostic accuracy and image quality. The investigators hypothesise that the new MR scan will have the same diagnostic accuracy as invasive coronary angiography, with no differences in interpretation of the images across the 5 different hospitals. If proven effective, this would demonstrate that MR scanning of the coronary arteries could prove a safe, clinically useful alternative to both CT scanning and invasive assessment of coronary artery narrowing. In addition, if there is no difference across different locations, it would demonstrate that these scans can be performed consistently, facilitating implementation on a healthcare-system wide basis.
This single-centre cross-sectional study aims to ascertain the impact of dyslipidemia on long-term graft patency after coronary artery bypass grafting (CABG).
With the emergence of advanced technology to date in the artificial intelligence (AI), computer aided diagnosis has gradually gained its popularity in the field of healthcare. Particularly, in the clinical practice of coronary artery disease diagnosis, the application of AI could be of great implication in alleviating the shortage of medical sources. To evaluate the effectiveness and safety of the AI-based coronary CT angiographic analysis software (RuiXin-CoronaryAI) for diagnosis of coronary artery stenosis, a retrospective, multi-center, cross-over designed, blinded, sensitivity superiority and specificity non-inferiority clinical trial will be conducted.
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.
The purpose of the current study is to assess complete coronary physiology (FFR, RFR, CFR, IMR, and CT-FFR) in TAVI candidates with intermediate coronary artery stenosis before and 6 months after TAVI. This aims to determine how TAVI affects coronary blood flow and coronary microcirculatory function after longer-term follow-up, and how these effects influence FFR and RFR values. In addition, it is aimed to correlate invasive functional testing (FFR and RFR) with non-invasive CT-FFR before and 6 months after TAVI.
