Filter by:A Prospective, Multicentre, Pilot Study to Evaluate the Safety and Performance of the AdvaPro Sirolimus Eluting Coronary Stent System in Coronary Artery Stenosis in Indian and European Population. To evaluate the performance of AdvaPro Sirolimus Eluting Stent follow up indicated by MACE at 9 months. Of the 120, 40 patients will be assigned to European population and 80 patients will be assigned to Indian population. QCA is applicable for only in sub-strategy participants at baseline and 9 month follow-up visit. A QCA Analysis will be performed on minimum 48 patients in Indian population only. Interval(Days) for patients visit at Day 0, Day 30±6, Day 180±8, Day 270±10 and Day 360±14.
Evidence for the usefulness of the defibrillator in cases of preserved left ventricular ejection fraction and well-tolerated ventricular tachycardia (without cardiocirculatory arrest or syncope) is lacking, as no previous trials have included such patients. Additionally, sudden death in this particular population is low compared to other subgroups of patients with malignant ventricular arrhythmias. On the other hand, numerous recent retrospective data show that ablation of ventricular tachycardia can reduce mortality, and also clearly reduces the number of recurrences in prospective studies. Finally, a very low rate of sudden death was observed in a multicenter European retrospective study that we conducted, including patients with well-tolerated ventricular tachycardia in structural heart disease with minimally impaired ejection fraction and benefiting from ablation without implantation of defibrillator.
This trial adopts a prospective, multicenter, randomized controlled, and non-inferiority comparison trial design, and plans to recruit 200 eligible subjects who will be randomly assigned to the experimental group or the control group in a 1:1 ratio. All randomly enrolled subjects will be followed up until 30 days after the surgery.
Phase 2, single-center, randomized, blinded clinical study to assess the safety and efficacy of topical nitroglycerin on ease of TRA during scheduled PCI. We will compare topical nitroglycerin to placebo applied prior to planned, non-urgent PCI to determine if nitroglycerin is associated with decreased number of arterial puncture attempts made, decreased time to radial access, and lower crossover rate to TFA. Subjects will be randomized to receive either topical nitroglycerin ointment or placebo prior to scheduled PCI. There will be 256 subjects enrolled in this study with 1:1 randomization.
The IMAGINATION trial is an investigator-initiated, prospective, single-center study of symptomatic patients with a native chronic total occlusion (CTO) undergoing intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) with a drug-coated balloon (DCB). Post-PCI IVUS and fractional flow reserve (FFR) at baseline and at 6-months follow-up will be performed. In addition, patients included in the coronary computed tomography angiography (CCTA) substudy will undergo photon-counting CCTA at 12-months follow-up. The aim of this study is to evaluate the efficacy and safety of DCB-only approach in native coronary CTO.
This is a multicenter, randomized, single-blind pivotal study to evaluate the safety and efficacy of the MagicTouchTM Drug coated balloon in treatment of small vessels in patients with coronary artery disease. The objective is to establish the safety and efficacy of the Magic TouchTM Drug coated balloon in treatment of small vessels (≤2.75 mm). A total of 1605 subjects will be enrolled in a maximum of 50 study sites located in North America. Additional sites located in Europe and South America may also participate in the study, with non-US sites contributing a maximum of ~50% of enrollees.
The aim of this study is to investigate the agreement and reproducibility between intravenous and intracoronary adenosine administration during invasive assessment of microvascular function. Goals of this study are: 1. Agreement and reproducibility between intravenous and intracoronary adenosine administration in the IMR (Index of microvascular resistance) value. 2. Agreement and reproducibility of FFR(fractional flow reserve), CFR (coronary flow reserve), MRR (microvascular resistance reserve), RRR (resistive reserve ratio) and reproducibility of each of these as compared with CFRabs (absolute coronary flow). 3. Time required for IMR measurements
The cardiorespiratory system integrates systemic and pulmonary circulation while ensuring adequate oxygenation of the body at rest and during exercise. In addition to chronic respiratory problems that mainly affect the lungs, airways and pulmonary vascular system, respiratory capacity and respiratory muscle strength can be negatively affected in a wide spectrum including cardiac diseases, surgeries, neuromuscular diseases, obesity, long-term bed rest, aging and inactivity. Weakness of the respiratory muscles causes important secondary consequences by causing the increased respiratory demands not to be met during physical activity. It has been reported that respiratory muscle training applied within the scope of pre-operative and post-operative cardiac rehabilitation program is beneficial in terms of increasing respiratory functions, reducing the risk of post-operative complications and length of stay. Respiratory muscle training is known to have many potential beneficial effects on patients undergoing cardiac surgery. Different methods and devices are used to improve and develop the functions of the inspiratory and expiratory muscles and each training method and device has differences. Therefore, it is thought that examining the clinical effects of using a personalized breathing exercise device on respiratory functions, respiratory muscle strength and functional capacity in individuals who have undergone cardiac surgery will contribute to the literature.
Teams of several medical professionals conduct high-risk cardiac surgical procedures. These professionals work in complex, stressful operating room environments requiring effective communication and teamwork skills. Surgeons, anesthesiologists, perfusionists, nurses, and surgical technicians working in this environment are also vulnerable to human errors. Non-technical skills for surgeons (NOTSS), defined as cognitive skills (situation awareness, decision making) and social skills (leadership, communication, and teamwork) underpinning medical knowledge and technical skills, are essential contributors to better cardiac surgery outcomes. Yet most of the surgical education programs focus only on technical skills, and interventions to improve the non-technical skills of cardiac surgical teams are scarce. The proposed research will develop and pilot-test and evaluate the preliminary effectiveness of an intervention to improve the non-technical skills of cardiac surgical teams.
This is a prospective clinical study aiming to investigate the efficacy of Magnetocardiography (MCG) in detecting myocardial ischemia in patients of a suspected non-ST-elevation-acute coronary syndrome (NSTE-ACS) by using Single photon emission computed tomography (SPECT) as the gold standard for determining the presence and severity of myocardial ischemia.
