“…More extensive areas of involvement result in hypoplasia. Coarctation has a prevalence of 0.01 to 0.03% and is seen in 0.2% of hypertensive adult patients [33]. Coarctation produces concentric LVH due to pressure overload.…”

“…Presence of higher flow in the distal segment of descending thoracic aorta compared to the proximal segment is an indicator of hemodynamically significant obstruction due to filling of the distal aorta by collateral vessels. LVH is seen in 20–40% of coarctation [33, 34]. Subendocardial ischemia and abnormal arterial stiffness are also seen [1].…”

Left ventricular (LV) thickening can be due to hypertrophy (concentric, asymmetric, eccentric) or remodelling (concentric or asymmetric). Pathological thickening may be caused by pressure overload, volume overload, infiltrative disorders, hypertrophic cardiomyopathy, athlete’s heart or neoplastic infiltration. Magnetic resonance imaging (MRI) plays an important role in the comprehensive evaluation of LV thickening, including: establishing diagnosis, determining LV geometry, establishing aetiology, quantification, identifying prognostic factors, serial follow-up and treatment response. In this article, we review the aetiologies and pathophysiology of LV thickening, and demonstrate the comprehensive role of MRI in the evaluation of LV thickening.Teaching Points• MRI plays an important role in the evaluation of LV thickening.• LV thickening can be due to either hypertrophy or remodelling.• Pathological thickening can be due to pressure/volume overload or infiltrative disorders.Electronic supplementary materialThe online version of this article (doi:10.1007/s13244-017-0549-2) contains supplementary material, which is available to authorized users.

“…Coarctation accounts for 0.2% of HTN in adults [16] and several imaging techniques can be used in its detection. Transthoracic and transesophageal echocardiography with Doppler techniques can usually detect the coarctation and record the transcoarctation pressure gradient, but their limitations include problems with poor acoustic windows, difficulty in the alignment of Doppler with flow and poor detection of collateral circulation.…”

Systemic hypertension is a highly prevalent potentially modifiable cardiovascular risk factor. Imaging plays an important role in the diagnosis of underlying causes for hypertension, in assessing cardiovascular complications of hypertension, and in understanding the pathophysiology of the disease process. Cardiovascular magnetic resonance (CMR) provides accurate and reproducible measures of ventricular volumes, mass, function and haemodynamics as well as uniquely allowing tissue characterization of diffuse and focal fibrosis. In addition, CMR is well suited for exclusion of common secondary causes for hypertension. We review the current and emerging clinical and research applications of CMR in hypertension.
