TCT-273 Coronary Lumen Eccentricity is Associated with Amount of Drug Adhesion after Treatment with Drug Coated Balloon
Unique angiographic findings in a patient with myocardial ischemia and immunoglobulin G4-related disease
Immunoglobulin G4-related disease characteristically involves multiple organs including the heart and coronary arteries. Immunoglobulin G4-related coronary artery disease is thought to be due to periarteritis and histopathologically is characterized by marked thickening of the adventitia and periarterial fat with infiltration of immunoglobulin G4-positive plasma cells. Although comprehensive diagnostic criteria require a biopsy for a definite or probable diagnosis of immunoglobulin G4-related disease, obtaining a coronary artery biopsy is difficult and risky. However, imaging findings including coronary angiography and intravascular ultrasound might be useful tools to establish a diagnosis of immunoglobulin G4-related coronary artery disease. We report a case of a 63-year-old man with a history of immunoglobulin G4-related disease who presented with exertional chest pain. We found unique angiographic and intravascular ultrasound features of immunoglobulin G4-related coronary artery disease that distinguished it from those of arteriosclerotic coronary artery disease and suggest that coronary angiography and intravascular ultrasound might be useful tools in the diagnosis of immunoglobulin G4-related coronary artery disease
HDL-C and Plaque Calcification are Associated with Microcirculatory Damage after Percutaneous Coronary Intervention
Aims: Microvascular disturbance followed by percutaneous coronary intervention (PCI) was sometimes occurred. There were no report of the quantitative evaluation about microvascular disturbance after PCI. The aim of this study was to quantitate microcirculatory injury caused by elective PCI using index of microcirculatory resistance (IMR), and to clarify preprocedural predictors of microvascular damage.Methods: Fifty patients with stable angina and planned PCI for single vessel disease were enrolled in this study. IMR was measured after PCI. Plaque components were analyzed by integrated backscatter intravascular ultrasound.Results: Post-PCI IMR tended to correlate with high-density lipoprotein cholesterol levels (r = –0.298, p = 0.078) and plaque calcification (r = -0.22, p = 0.058) in the univariate analysis. Multivariate logistic analysis adjusted for these covariates revealed that the high-density lipoprotein cholesterol levels and plaque calcification were inversely associated with higher post-PCI IMR (odds ratio = 0.919, p = 0.049; and odds ratio = 0.546, p = 0.049, respectively).Conclusion: Low levels of high-density lipoprotein cholesterol and plaque calcification independently predict higher post-PCI IMR. Based on these results, Serum lipid and plaque calcification profiles might be important for predicting and preventing periprocedural myocardial damage during elective PCI
