27 Clinical Trials for Various Conditions
In this randomized clinical trial, the researchers are investigating whether a multi-component virtual/hybrid cardiac rehabilitation program will improve functional status, cholesterol level, overall cardiovascular health, individual risk factors, quality of life and mental health for patients who have recently been diagnosed with myocardial infarction, received a coronary stent, underwent heart surgery or catheter-based valve replacement, as compared to traditional, center-based cardiac rehabilitation.

The ABSORB III PK sub-study is a prospective, open-label, non-blinded study enrolling approximately 12 subjects in up to 5 US sites. ABSORB III PK sub-study is a part of ABSORB III RCT (NCT01751906). The objective is to determine the pharmacokinetics of everolimus delivered by the Absorb BVS in a separate and non-randomized cohort of subjects who only receive Absorb BVS with a maximum of two de novo native coronary artery lesions after implantation of the Absorb BVS. Note: The ABSORB III PK subjects will not contribute to the determination of the ABSORB III RCT primary endpoint.
ABSORB IV is a prospective, randomized (1:1, Absorb BVS to XIENCE), single-blind, multi-center study, registering approximately 2610 subjects from approximately 140 sites in the United States and outside the United States. ABSORB IV is a continuation of ABSORB III (NCT01751906) trial which are maintained under one protocol because both trial designs are related. The data from ABSORB III and ABSORB IV will be pooled to support the ABSORB IV primary endpoint. Both the trials will evaluate the safety and effectiveness of Absorb BVS. The ABSORB IV Randomized Controlled Trial (RCT) is designed to continue to evaluate the safety and effectiveness as well as the potential short and long-term benefits of Abbott Vascular Absorb™ Bioresorbable Vascular Scaffold (BVS) System, and the Absorb GT1™ BVS System (once commercially available), as compared to the commercially approved, control stent XIENCE.
It is universally accepted that high-pressure balloon inflation is required to most effectively deploy a coronary balloon-expandable stent. However, there is not consensus nor are there any guidelines regarding the method of balloon inflation, particularly the duration of inflation. Underexpansion and strut malapposition after stent deployment are among the most powerful predictors for adverse vessel outcomes. High-pressure inflation for stent deployment is effective to optimally expand the stent, but unlike in vitro testing in air, there are poorly distensible plaque elements that may not instantaneously yield to the balloon pressure. However, these elements may ultimately yield to prolonged inflation. Most clinical interventional cardiologists inflate for a relatively short period (15-30 sec). The investigators have noted that when balloon pressure is maintained at a certain pressure level it tends to decrease over time, and may require 60-180 or more seconds to maintain pressure stability. This finding implies that plaque elements are yielding slowly over time to the increased pressure, thus increasing expansion, and suggests that a prolonged inflation until balloon pressure stabilizes is more effective than a rapid inflation/deflation sequence to fully expand and appose the stent to the vessel wall. At present there is no consensus on stent deployment strategy. It is our hypothesis that prolonged inflation is superior to the more commonly used strategy of rapid inflation/deflation. Optimal coherence tomography (OCT), a novel technology that measures near-infrared light reflections and translates them into a 2D image, has an axial resolution nearly 10-times that of intravascular ultrasound (IVUS). Thus it is possible to examine the extent of stent malposition and stent expansion using this modality. The current randomized trial tests the hypothesis that prolonged balloon inflation until a stable balloon pressure is maintained is more effective than a rapid inflation/deflation sequence when performed to the same balloon inflation pressure.
To evaluate the safety and efficacy of the Absorb BVS System compared to the XIENCE V Everolimus Eluting Coronary Stent System (EECSS) in the treatment of subjects with ischemic heart disease caused by up to two de novo native coronary artery lesions in separate epicardial vessels.
The ABSORB III RCT is a prospective randomized, single-blind, multi-center trial. It is the pivotal trial to support the US pre-market approval (PMA) of Absorb™ Bioresorbable Vascular Scaffold (BVS). The ABSORB III includes additional two trials i.e. ABSORB III PK (pharmacokinetics) sub-study and ABSORB IV RCT trial which are maintained under one protocol because both trial designs are related, ABSORB IV is the continuation of ABSORB III and the data from ABSORB III and ABSORB IV will be pooled to support the ABSORB IV primary endpoint. Both the trials will evaluate the safety and effectiveness of Absorb BVS.

The objective of this prospective, single-blind clinical investigation is to demonstrate the superiority of an Optical Coherence Tomography (OCT)-guided stent implantation strategy as compared to an angiography-guided stent implantation strategy in achieving larger post-PCI lumen dimensions and improving clinical cardiovascular outcomes in patients with high-risk clinical characteristics and/or with high-risk angiographic lesions.
The primary aim of the trial is to determine whether preventive PCI with bioabsorbable vascular scaffolds (BVS) (early period) or everolimus-eluting stents (middle and late period) plus optimal medical therapy (OMT) on functionally insignificant (FFR \> 0.80) vulnerable coronary plaque, as determined by intracoronary imaging, would result in a significant reduction of the primary composite outcome of death from cardiac causes, target-vessel myocardial infarction (MI), target-vessel revascularization (TVR), and hospitalization for unstable or progressive angina at 2 years, when compared with OMT alone.
The study hypothesis: it is possible to use icECG recorded from regular PCI wire to predict significance of SB ostial stenosis after main vessel stenting in coronary bifurcation lesions.
This study tests the hypothesis that repeated inflation of a blood pressure cuff on the arm will improve results of coronary stent implantation by: * reducing chest pain and electrocardiogram changes during balloon inflation to place the stent * reducing leakage of heart muscle protein(troponin) into the blood stream after stent placement, indicated reduced damage to heart muscle during stent implantation * increases in molecules in the blood that promote dilation of arteries * reduced evidence of heart muscle damage on MRI immediately after stenting * improved patient outcomes over six months with fewer adverse cardiovascular events(heart attack, acute coronary syndrome,renarrowing of the stented artery, heart failure, death, stroke, transient ischemic attack) * improved heart structure and function at 6 months after stenting
