View clinical trials related to Coronary Occlusion.
Filter by:The objective of this research study is to test the accuracy of preexisting criteria versus expert interpretation for the diagnosis of acute coronary occlusion (major heart attack due to a completely blocked blood vessel). If our hypothesis proves to be true, this would provide a significant improvement in the care for patients who present to the hospital with possible symptoms of coronary ischemia (symptoms due to lack of blood flow to the heart). The primary analysis will be designed as a multi-center, retrospective case-control study.
Rationale: Randomized trials could not yet establish favourable outcomes of CTO PCI on hard endpoints such as ejection fraction or mortality, when compared to optimal medical therapy. However, patients after CTO PCI appeared to be more frequently free of angina complaints, but the aetiology behind this is not fully understood. The investigators hypothesize that PCI of the CTO in patients preselected with an ischemic threshold (>12.5%) on cardiac imaging leads to a reduction of the ischemic burden and therefore an increased benefit on functional outcomes. Objective: Primary objective is to determine whether PCI of the CTO will yield a higher reduction of ischemia assessed by exercise myocardial perfusion SPECT-CT from baseline to 6-month follow-up compared to a control group. Secondary objectives are 1) to evaluate the effect of PCI of the CTO on improvement in functional status, infarct size and left ventricular function from baseline to follow-up compared to the control group; 2) to study the association between ischemia reduction and functional outcome and left ventricular function; 3) to assess the influence of the collateral flow index on the ischemic burden (reduction), functional status, infarct size and left ventricular (contractile) function (hibernation). Study design: open multicentre randomized trial Study population: 82 patients eligible for CTO PCI Intervention: CTO PCI Primary endpoint: ischemic burden assessed with exercise myocardial perfusion SPECT-CT from baseline to 6 months follow-up.
This study evaluates effectiveness and safety of DESyne X2 in Routine Clinical Practice.
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 of MI. Left-sided coronary occlusions may be associated with a more favorable pre-hospital phase of acute MI compared to proximal RCA occlusions. Proximal RCA occlusion increases the risk of arrhythmia and shock leading to increase the mortality. Sinus bradycardia and cardiogenic shock accounts for the majorities of the mortalities of RCA occlusion
Randomized registry for the study of CTO PCI as adjunction to optimal medical therapy.
This study will compare clinical outcomes of immediate stent implantation with deferred stent implantation(4-10days after primary angiography) for patients presented with acute myocardial infarction due to left main coronary artery occlusion.
The aim of this CTO registry is to gather data including patient demographic date, cardiac risk factors, procedural technical data and procedural success/outcome rates. Furthermore, we aim to evaluate the safety and performance of various CTO specific guidewires, devices (such as the CrossBoss/Stingray dissection re-entry device) and other recognised and approved techniques (retrograde wire escalation, retrograde dissection re-entry techniques). The incidence of recognized complications (dissections, perforations, cardiac tamponade, vascular complications, radiation injury, acute kidney injury) will also evaluated. The investigator will assess clinical outcome at 1 year after successful CTO procedures.
