41. It was at the right ventricle . 42. Patients with a large ductus develop progressive pulmonary vascular disease, and pressure overload of the right ventricle occurs. 43. This may lead to right ventricular failure ( dilatation and decreased systolic function of the right ventricle ). 44. Pathologic pressure mismatches between the pulmonary and systemic circulation guide compensatory remodeling of the left and right ventricles . 45. Right ventricular outflow tract tachycardia originates from the outflow tract of the right ventricle or the tricuspid annulus. 46. The right atrium squirts oxygen-depleted blood from the body into the right ventricle , which pumps it to the lungs. 47. The increased blood volume in the right ventricle causes the pulmonic valve to stay open longer during ventricular systole. 48. It is between the right atrium and the right ventricle , and stops the backflow of blood between the two. 49. The right vessel travels along the right atrium and the part of the right ventricle sitting on the diaphragm. 50. Tricuspid atresia is the complete absence of the tricuspid valve which can lead to an underdeveloped or absent right ventricle .
