Identifying Subclinical Coronary Abnormalities and Silent Myocardial Ischemia After Arterial Switch Operation.

Pediatr Cardiol 2019 Jun 9;40(5):901-908. Epub 2019 Mar 9.

Nemours Cardiac Center, Nemours/Alfred I. duPont Hospital for Children, 1600 Rockland Rd, Wilmington, DE, 19803, USA.

The incidence of late coronary complications is reported around 8% after arterial switch operation (ASO) for d-transposition of the great arteries, but the affected patients are usually asymptomatic. Exercise stress test (EST) and myocardial perfusion imaging (MPI) are common non-invasive modalities to screen for silent myocardial ischemia, but their diagnostic reliability in children after ASO is unclear. We retrospectively reviewed asymptomatic patients following ASO with EST, MPI, and coronary imaging studies (CIS) and examined the reliability of each test in identifying abnormal coronary lesions responsible for myocardial ischemia.

Risk Stratification and Treatment of Coronary Disease in Chronic Kidney Disease and End-Stage Kidney Disease.

Semin Nephrol 2018 11;38(6):582-599

Division of Nephrology, Stanford University School of Medicine, Palo Alto, California.

Patients with advanced chronic kidney disease have an enormous burden of cardiovascular morbidity and mortality, but, paradoxically, their representation in randomized trials for the evaluation and management of coronary artery disease has been limited. Clinicians therefore are faced with the conundrum of synergizing evidence from observational studies, expert opinion, and extrapolation from the general population to provide care to this complex and clinically distinct patient population. In this review, we address clinical risk stratification of patients with chronic kidney disease and end-stage kidney disease using traditional cardiovascular risk factors, noninvasive functional and structural cardiac imaging, invasive coronary angiography, and cardiovascular biomarkers.

Coronary computed tomographic imaging in women: An expert consensus statement from the Society of Cardiovascular Computed Tomography.

J Cardiovasc Comput Tomogr 2018 Nov - Dec;12(6):451-466. Epub 2018 Oct 23.

Weill Cornell Medicine, USA.

This expert consensus statement from the Society of Cardiovascular Computed Tomography (SCCT) provides an evidence synthesis on the use of computed tomography (CT) imaging for diagnosis and risk stratification of coronary artery disease in women. From large patient and population cohorts of asymptomatic women, detection of any coronary artery calcium that identifies females with a 10-year atherosclerotic cardiovascular disease risk of >7.5% may more effectively triage women who may benefit from pharmacologic therapy.
