[Treatment for ventricular arrhythmias in the absence of structural heart disease: from guidelines to clinical practice].

Aim: To determine criteria for choosing management tactics in patients with ventricular arrhythmias (VA) in the absence of structural heart disease from the point of view of physicians and patients in clinical practice and to compare the immediate results of antiarrhythmic drug therapy (ADT) and radiofrequency ablation (RFA) with the trends in arrhythmic syndrome in the non-treatment group.

Subjects And Methods: Examinations were made in 90 patients (23 men and 67 women) (mean age, 44 (31; 57) years) with VA in the absence of structural heart disease. Preference was given to RFA (n = 32 (36%)), ADT (n = 37 (41%)), and follow-up tactics (n = 21 (23%)).

Hemodynamic physiology in aortic arch and trigger factors of atherosclerosis.

Magnetic resonance angiography showed that blood flow in the aortic arch during protodiastole is separated into the opposite flows, which are temporarily arrested at the certain sites creating the flat front of the flow. The protodiastolic antegrade peak acceleration 6-fold surpasses the systolic one. Due to adhesion, the high gradient pressure forces can damage the vascular wall.
