The aim of this study is to assess the feasibility and validity of patient-level randomization (vs. cluster randomization) in pilot trials of decision aid efficacy.
This is a parallel, 2-arm, randomized trial to compare an intervention group receiving CTO Choice (decision aid) to a control group receiving usual primary care. 100 patients and 60 cardiologists will be randomize by computer. The investigators will measure the effect of CTO Choice on five outcomes: (a) patient knowledge regarding CTO of PCI or medication (risk and benefit); (b) quality of the decision making process for both the patient and clinician; (c) patient and clinician acceptability and satisfaction with the decision aid; (d) rate of percutaneous coronary intervention (PCI) or medication; and (e) trial processes (e.g., ability to recruit participants, collect patient outcomes). To capture these outcomes, the investigators will use patient and clinician surveys following each visit and video recordings of the clinical encounters. These video recordings will also allow us to determine the extent to which clinicians exposed to the decision aid were able to recreate elements of the decision aid which control patients.

The aim of this study is to investigate the role of functional evaluation for predicting clinical outcome in patients with coronary chronic total occlusion (CTO) undergoing percutaneous co...
Proximal RCA occlusions were very often found among men with fatal pre-hospital MI; whereas left-sided coronary occlusions were significantly more frequent in hospital-admitted survivors o...
Lesions involving coronary bifurcations account for approximately 20% of all percutaneous coronary interventions (PCI). Revascularization within bifurcation sites remains technically chall...
The purpose of this study is to investigate the effect of percutaneous coronary intervention (PCI) on cardiac function in multi-vessel disease patients with concurrent chronic total occlus...
Under the circumstances that appropriate first-choice guidewires for percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) have yet to be established, the objective of...
Aorto-coronary occlusion is a particularly difficult lesion to treat, especially in an emergent setting. To our knowledge, this is the first description of the use of a microcatheter not to support th...
Electrocardiographic diagnosis of acute coronary occlusion can be difficult in the setting of left bundle branch block. If presumably new bundle branch block is considered equivalent to ST-elevation m...
Limited study has detailed the procedural outcomes and utilization of contemporary coronary guidewires and microcatheters designed for chronic total occlusion (CTO) percutaneous revascularization and ...
The study was aimed at assessing remote (up to 42 months) results of coronary artery bypass grafting (CABG) and revealing flowmetric and angiographic predictors of coronary bypass graft occlusion.
Coronary computed tomography angiography (CTA) has emerged as a non-invasive diagnostic method for patients with suspected coronary artery disease, but its usefulness in patients with complex coronary...
Complete blockage of blood flow through one of the CORONARY ARTERIES, usually from CORONARY ATHEROSCLEROSIS.
A family of percutaneous techniques that are used to manage CORONARY OCCLUSION, including standard balloon angioplasty (PERCUTANEOUS TRANSLUMINAL CORONARY ANGIOPLASTY), the placement of intracoronary STENTS, and atheroablative technologies (e.g., ATHERECTOMY; ENDARTERECTOMY; THROMBECTOMY; PERCUTANEOUS TRANSLUMINAL LASER ANGIOPLASTY). PTCA was the dominant form of PCI, before the widespread use of stenting.
A complication of INTERNAL MAMMARY-CORONARY ARTERY ANASTOMOSIS whereby an occlusion or stenosis of the proximal SUBCLAVIAN ARTERY causes a reversal of the blood flow away from the CORONARY CIRCULATION, through the grafted INTERNAL MAMMARY ARTERY (internal thoracic artery), and back to the distal subclavian distribution.
A graphic device used in decision analysis, series of decision options are represented as branches (hierarchical).
Abnormal balloon- or sac-like dilatation in the wall of CORONARY VESSELS. Most coronary aneurysms are due to CORONARY ATHEROSCLEROSIS, and the rest are due to inflammatory diseases, such as KAWASAKI DISEASE.
