Accuracy of RESOLVE score derived from coronary computed tomography versus visual angiography to predict side branch occlusion in percutaneous bifurcation interventionVisually estimated angiographic V-RESOLVE score was developed as a simple and accurate prediction tool for side branch (SB) occlusion in patients undergoing coronary bifurcation intervention. Data on the use of coronary computed tomography angiography (coronary CTA) for guiding percutaneous coronary intervention in bifurcation lesions is scarce.
Proving the innocence of a “malignant” coronary artery: Calling dobutamine stress CT for the defence!A 49-year-old lawyer underwent an exercise test for an insurance physical. In recovery, he had frequent premature ventricular complexes and asymptomatic runs of monomorphic non-sustained ventricular tachycardia (NSVT) not preceded by ST segment shift or chest pain, suspicious for non-ischemic, anterior fascicular VT.
Dual-source computed tomography angiography for diagnosis and assessment of coronary artery disease: Systematic review and meta-analysisDevelopment of an accurate test for noninvasive assessment of coronary arteries has been highly desirable.
Recurrent Takotsubo cardiomyopathyWe present the case of a 71-year-old woman with Takotsubo Cardiomyopathy as imaged with a dual source multidetector CT, MRI, and follow-up echocardiography. This demonstrates normal coronary arteries by use of CT angiography, and a 3D perspective of abnormal mid left ventricular hypokinesis and apical left ventricular akinesis.
Inadvertent anastomosis of saphenous vein graft to a cardiac vein detected with coronary computed tomographic angiographyA 34-year-old man with a prior history of Hodgkin’s disease and coronary artery bypass surgery for radiation-induced left main disease presented with persistent chest pain. Cardiac catheterization showed near simultaneous filling of the venous system during arterial injection and could not precisely delineate the insertion point of the vein graft anastamosis to the diagonal branch, and the patient was referred for coronary computed tomography angiography (CTA). CTA demonstrated that the anastamosis of the graft was with a cardiac vein.
