Is right ventricular myocardial deformation affected by degree of interatrial shunt in adults?
Regional RV deformation (ε/SR) does not differ significantly in the group of patients with various degrees of the left-to-right shunts when compared with healthy subjects. However, a non-linear correlation between Qp/Qs and ε could be observed. The affected region of the RV wall is the mid-segment and the highest values of ε were recorded in patients with moderate left-to-right shunts.
Pregnancy increases thyroid volume, particularly when combined with tobacco smoking and iodine deficiency. The effect is probably reversible seen over a spectrum of several years.
