References This is an open-access article distributed under the terms of the Creative Commons Attribution License Comments Marked PVS has an unfavorable evolution, even at an early age in the neonatal period, as it can progress to sudden death due to right ventricular failure. After this age range, the disease evolution becomes more adequate, but right ventricular dysfunction, tricuspid valve regurgitation, arrhythmias and right heart failure appear in adulthood. These factors shorten patient survival to 30 to 40 years of age. Therefore, percutaneous pulmonary valvuloplasty has been indicated at early ages, aiming to prevent such unfavorable evolution. Thus, it can be affirmed that patient evolution in this clinical case is very peculiar, due to the marked degree of the congenital defect at a very old age. Also noteworthy is the rare occurrence of good ventricular function preservation and, as a result, the occurrence of few symptoms. A similar evolution has also been observed by other authors with percutaneous, 1,2 as well as surgical treatment 3 in adulthood. However, the literature shows that the effectiveness of percutaneous valvuloplasty becomes lower in adults (87%) in relation to younger ages (96%). 4 429
