Computed Tomography Angiography Prediction Score for Side Branch Occlusion

Lesions involving coronary bifurcations account for approximately 20% of all percutaneous coronary interventions (PCI). Revascularization within bifurcation sites remains technically challenging. While the most optimal interventional treatment strategy for bifurcation lesions is still debatable, side branch (SB) occlusion is one of the most serious procedural complications with prevalence rates over 7%. Numerous mechanisms of the SB occlusion (e.g. plaque or carina shift, coro...

Coronary Artery Plaque Burden in Stable Angina and Non-obstructive Coronary Artery Disease

Non-obstructive coronary artery disease (CAD), particularly common in women, has been associated with impaired quality of life and risk of recurrent hospitalizations. Several studies have also demonstrated increased risk of incident acute coronary events and mortality. The main objective of the project is to assess the association between coronary artery plaque features by coronary CT angiography and long term prognosis in a large unselected population undergoing CT coro...

Computed Tomographic Angiography or Conventional Coronary Angiography in Clinical Decision Making

Patients planned for elective conventional coronary angiography will undergo CT coronary angiography (Dual Source CT) in order to assess the correlation of stenosis detection and therapeutic advice between conventional and CT coronary angiography. We hypothesize that their is a good correlation between conventional and CT coronary angiography for stenosis detection and therapeutic advice.

Randomised Controlled Trial to Assess Whether Computed Tomography Cardiac Angiography Can Improve Invasive Coronary Angiography in Bypass Surgery Patients

A large number of patients with symptomatic ischaemic heart disease undergo coronary artery bypass grafting (CABG) to alleviate their symptoms and improve prognosis. Given the progressive nature of coronary disease, bypass grafts can narrow or block over time, leading to chest pain and the need for further invasive coronary angiography. Invasive coronary procedures in patients with bypass grafts can be more complicated due to the variation in bypass graft ostia. This can lead t...
