Filter by:This pilot study (n=20) is a prospective evaluation of the implementation of an indoor air pollution intervention among patients who have undergone recent percutaneous coronary intervention procedures. The intervention, called Air Improvement and Real-time Monitoring for Wellness through Interactive Strategies and Education (AIRWISE), is focused on improving indoor air quality through air filtration, education, and behavioral recommendations. All participants will receive the AIRWISE intervention with the objective of evaluating acceptance and use of the individual intervention components. This implementation study will inform the submission of a larger NIH proposal for a randomized trial. The central study hypothesis is that an intervention program with educational strategies and visual behavioral cues will increase knowledge and awareness of air pollution exposures among the participants and lead to improved intervention compliance.
The study objective is to compare standard CABG to a hybrid revascularization strategy (RA-MIDCAB + PCI) in patients who have multi-vessel CAD and an indication for surgery, but who have a slightly higher risk of post-operative complications.
The goal of this interventional is to assess advantages of the ultrasound examination of the lungs in the early postoperative period in cardiac surgical patients after heart surgeries requiring cardiopulmonary bypass. Evaluation of pulmonary complications and outcomes during mid-term follow-up, as well as comparison of ultrasound examination and traditional roentgenologic methods (X-ray examination and CT of the chest) will be performed. The main question[s] it aims to answer are: - Is ultrasound examination of the lungs a more specific and sensitive method in identification of early postoperative pulmonary complications after on-pump cardiac surgical procedures, in comparison with traditional X-ray methods. - Does early identification of interstitial pulmonary edema (based on number of visualised B-lines in the early postoperative period), influences mid-term outcomes in this cohort of patients Participants will undergo ultrasound examination of the lungs on postoperative day 1, 3, 5 and 7 after heart surgery. Based on ultrasound findings and degree of interstitial pulmonary edema, medical (diuretics, anti-inflammatory, e.t.c) therapy will be modified. Researchers will compare this group of patients with control group, in which ultrasound examination will be performed in the same time frames, but no changes in medical management based on ultrasound findings will be made to see if timely administered medical therapy, based on ultrasound findings, can significantly improve symptoms, hospital lengths of stay and outcomes of this patients.
Patients undergoing coronary angiography for stable or acute coronary disease presentations and eligible for percutaneous coronary intervention (PCI) will be imaged with OCT-NIRAF at baseline and with CCTA 12 months apart to demonstrate that: 1. NIRAF coronary artery signal level (patient, artery, lesion basis) is correlated with the severity of coronary artery disease. 2. NIRAF coronary artery signal level is a predictor of plaque progression on a per patient, per artery, or per lesion basis.
The objective of the study is to compare angiographic outcomes of Selution sirolimus coated balloon (MedAlliance) versus SeQuent Please Neo paclitaxel coated balloon (Bbraun) for the treatment of de novo coronary artery lesions in medium size vessels (>2.00 mm and ≤3.00 mm) with respect to Net Gain (mm) at 12 months follow-up.
The clinical trial is intended to evaluate the efficacy, safety and economic benefit of coronary lithotripsy compared to other additional procedures (cutting or super high pressure balloon angioplasty, ablative procedures) in lesion preparation and interventional treatment of severely calcified coronary stenoses.
This study aims to determine the factors affecting exercise adherence in patients with coronary artery disease (CAD). For this purpose, the following measurement tools will be used respectively: (1) "Patient Information Form" including sociodemographic characteristics of the patients and medical information related to the disease, (2) the Exercise Adherence Rating Scale (EARS), (3) Exercise Self-Efficacy Scale (ESE) and, (4) Turkish-Health Literacy Survey Europe-Q12 (HLS-EU-19-12Q-TR). Statistical analyses will be carried out by descriptive statistics (number, percentage, mean, standard deviation, etc.), correlation analysis and regression analysis.
A prospective, open label, multi-center, single arm, observational study designed to evaluate the acute safety and device performance of the Sapphire 3 0.85, 1.0 and 1.25mm diameter coronary dilatation catheter in predilatation of Chronic Total Occlusion (CTO) lesions during percutaneous coronary intervention. One hundred seventy (170) subjects will be enrolled with a target of one hundred fifty-three (153) evaluable subjects by the angiographic core laboratory at up to 15 clinical sites with the Sapphire 3 0.85, 1.0 and 1.25mm diameter PTCA dilatation catheter to pre-dilate CTO lesions in coronary arteries during their index procedure. All subjects will be screened according to the protocol inclusion and exclusion criteria and will be followed through study completion, which is defined as 24-hours post-procedure or hospital discharge, whichever comes first.
The goal of this clinical trial is to learn if simulator-based training will improve interventional cardiology fellows' skills and will improve patient outcomes. The main questions it aims to answer are: - Does this training improve specific operative parameters recorded during initial coronary interventions performed as first operators under senior supervision? - Will major and minor procedural complications be reduced after simulator-based training? Interventional cardiology fellows in their first year of training will be randomized between standard master-apprentice training or simulator-based training before starting their cath lab period. They will be supervised during their cath lab period as first operators by senior interventional cardiologists. During their first 50 procedures performed as supervised first operator, specific procedural data will be collected.
The primary purpose of this clinical trial is to evaluate the safety and efficacy of the percutaneous left ventricular assist system versus intra-aortic balloon pump (IABP) for Circulatory Support during High-risk PCI.
