A Novel Algorithm to Quantify Coronary Remodeling Using Inferred Normal Dimensions.

Background: Vascular remodeling, the dynamic dimensional change in face of stress, can assume different directions as well as magnitudes in atherosclerotic disease. Classical measurements rely on reference to segments at a distance, risking inappropriate comparison between dislike vessel portions.

Objective: to explore a new method for quantifying vessel remodeling, based on the comparison between a given target segment and its inferred normal dimensions.

Comparison between MDCT and Grayscale IVUS in a Quantitative Analysis of Coronary Lumen in Segments with or without Atherosclerotic Plaques.

Background: The diagnostic accuracy of 64-slice MDCT in comparison with IVUS has been poorly described and is mainly restricted to reports analyzing segments with documented atherosclerotic plaques.

Objectives: We compared 64-slice multidetector computed tomography (MDCT) with gray scale intravascular ultrasound (IVUS) for the evaluation of coronary lumen dimensions in the context of a comprehensive analysis, including segments with absent or mild disease.

Methods: The 64-slice MDCT was performed within 72 h before the IVUS imaging, which was obtained for at least one coronary, regardless of the presence of luminal stenosis at angiography.

Prognostic heterogeneity among patients with chronic stable coronary disease: determinants of long-term mortality after treatment with percutaneous intervention.

Aims: To evaluate the risk and predictors of death in a large population of patients with stable coronary disease treated with percutaneous intervention.

Methods And Results: The study population comprised 1,276 patients with chronic angina or silent ischaemia who underwent elective coronary angioplasty. Baseline and in-hospital mortality data were prospectively collected for all patients during the index hospitalisation.

Angiographic segment size in patients referred for coronary intervention is influenced by constitutional, anatomical, and clinical features.

Background: Factors influencing the size of target vessels of patients referred for coronary intervention are poorly defined. We aimed to investigate in a large series of patients undergoing percutaneous intervention the relation of constitutional, anatomical, and clinical features with the reference diameter of coronary vessels treated with stenting.

Methods: A total of 4,850 de novo coronary lesions, non-ostial and non-bifurcational, located in native vessels were analyzed.
