Cardiac mri with paramagnetic contrast enhancement in assessment of supraventricular arrhythmias formation in patients with resistant hypertension

Present article is devoted to MRI assessment of the status of the left atrium (LA) in patients with resistant hypertension (RH) and left ventricular (LV) hypertrophy in the dynamics of treatment with transcatheter renal denervation (TRD). To achieve this the dynamics of the state of the LA during treatment was assessed; the relationship between the LV mass and the degree of dilation of the LA was analyzed. We studied 40 patients (mean age 56.6±8.4 years) with RH and LV hypertrophy who underwent TRD treatment. All patients received MRI study before TRD and after 6 and 12 months after the treatment. Based on MRI data, we quantified LA volume and LV mass. LA volume statistically significantly decreased 12 months after treatment (from initial 57.95 (47.28; 65.16) cm3 to 54 (44.58; 64.73) cm3 (p
