Filter by:A pragmatic, prospective, multi-center, open label, randomized controlled, superiority trial. The study will compare clinical outcomes between invasive versus non-invasive approach as next diagnostic step in symptomatic patients with non-high risk obstructive coronary artery disease (CAD) on coronary computed tomography-angiography (CCTA).
Authors hypothesize that "no-touch" saphenous vein as I graft is superior over conventional "no-touch" saphenous vein as free graft in the incidence of graft patency.
To establish if the cardiac radiation dose assesment is well aproximated with routine 3D CT scan compared to 4D CT experimental scan with respiratory gating (breath motion monitoring). The study population relates to left side breast cancers female patients that require a radiation therapy treatment.
This study aims to evaluate procedural and clinical outcomes of acute coronay syndrome (ACS) patients with aneurysmatic culprit right coronary artery (RCA).
This study aims to evaluate the clinical value of a novel CT gantry supporting a .23 second rotation time and systematically compare it with 0.23 second rotation time, in patients with clinically indicated aortic CTA in the workup of aortic stenosis. Patients will be randomly assigned .23 or .28 sec rotation time CTA. Coronary artery interpretability rates will be determined in both groups.
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.
Coronary CT angiography is challenging in patients with more than mildly calcified coronary vessels, because of calcium artefacts that prevents evaluation of the lumen. The purpose of the CCT-PCD-1-study is to evaluate the diagnostic accuracy and image quality in coronary CT angiography using a commercially available CT system equipped with a photon counting detector technology. Patients referred for cardiac CT and conventional coronary angiography as part of routine preoperative evaluation before Transcatheter Aortic Valve Implantation (TAVI) will be asked for inclusion in the study. This group of patients has generally a coronary artery calcium burden and perform cardiac CT and coronary angiography as part of routine care. The diagnostic accuracy concerning significant coronary artery stenosis on the preoperative CT will be evaluated with the conventional coronary angiography as reference. Also, CT examination image quality will be evaluated.
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 overall aim is to build an AI driven national Platform for CT cOronary angiography for clinicaL and industriaL applicatiOns (APOLLO) for automated anonymization, reporting, Agatston scoring and plaque quantification in CAD. It is a "one-stop" platform spanning diagnosis to clinical management and prognosis, and aid in predicting pharmacotherapy response.
Traditionally, the severity of a blockage (stenosis) in a coronary artery has been determined by visual angiographic assessment of the diameter of the artery at the level of a blockage compared to a normal healthy area of the same artery. With the advent of invasive physiological testing to assess coronary blood flow, multiple clinical trials have demonstrated a clinical benefit to a physiology-guided percutaneous coronary intervention (PCI) approach. However, despite this and the potential for significant variation in the interpretation of coronary artery stenosis severity by visual angiography alone to guide PCI, invasive physiologic indices remain significantly under-utilized. The purpose of this study is to investigate the physiologic significance of coronary lesions deemed angiographically severe by visual estimation that are planned for PCI. The investigators plan to perform blinded physiologic assessment pre and post PCI. The primary aim of the study is to determine whether a subset of lesions visually estimated as severe by angiography treated with stent placement/PCI may in fact not be physiologically significant when assessed invasively, and thus PCI could safely be deferred in these patients. A secondary aim is to evaluate physiologic assessment post PCI to detect residual ischemia that could be utilized to optimize stent placement.
