At 33 weeks pregnant, a severe hardness in the right lower abdomen was found during a false labor contraction, which should be the uterus when touched. When lying flat, the belly was also found to be tilted to the right, which should be uterine dextroversion. I wonder if this has any effect on the fetus? Is it normal? This condition usually does not affect and may self-heal. A ventricular septal defect found after one year will be lifelong. It is recommended to use a medical occluder for treatment or surgical treatment. Left-handed heart and right-handed heart refer to the abnormal position and axis of the heart. A right-handed heart indicates that the heart is located in the right chest, with the tip pointing to the right front, and the liver and stomach are still normal. The so-called midline heart refers to the center of the heart apex, with the interventricular septum positioned in a sagittal plane, and the position of the atria and ventricles is normal or shifted. As long as it does not affect hemodynamic changes, there is no problem.
