Pulmonary pressures are expressed, in the same fashion as systemic BP's, as systolic and diastolic. The mean or average pulmonary pressure is also usually recorded. If the pressure of 35 is a systolic pressure, I would agree with your cardiologist that it is nothing to be alarmed about and, depending on the cause, whether or not it is likely to get progressively higher. A systolic pressure of 35 is close to the upper limit of predicted normal values and could be a reflection of the mitral insufficiency. It may be helpful to consider repeating the echocardiogram in 6-12 months.
