Pulmonary Valve Stenosis

  • Pulmonary valve stenosis

    Pulmonary valve stenosis is a condition characterized by obstruction to blood flow from the right ventricle to the pulmonary artery. This obstruction is caused by narrowing (stenosis) at one or more points from the right ventricle to the pulmonary artery. The most common form of pulmonary stenosis is obstruction at the valve itself, referred to as pulmonary valvar stenosis.

  • Pulmonary valve stenosis

    Patients with mild pulmonary valve stenosis are healthy, can participate in all types of physical activities and sporting events, and lead normal lives. The type of treatment required depends on the type of valve abnormality present. Most commonly, the pulmonary valve is of normal size, and the obstruction is due to fusion along the commissures or lines of valve leaflet opening. This "typical" form of pulmonary valve stenosis responds very nicely to balloon dilation. Balloon dilation valvuloplasty is performed at the time of cardiac catheterization and does not require open-heart surgery.

  • Pulmonary valve stenosis

     In Ireland the statistical analysis of pulmonary valve stenosis got the result as the total of 52 patients were recruited for this study, 26 patients in the TOF group (15 males, age 12.55±2.9) and 26 patients in the ARVC group (15 males, age 15.6±2.3). In both groups, the RPA sizes were not significantly different between the DIR images and diastolic cine SSFP (p>0.05). Measurements on DIR were significantly smaller than those made on systolic cine SSFP or MRA in both groups (p<0.0001). Vessel diameters measured on systolic SSFP were significantly larger than measurements made on diastolic SSFP (p<0.0001). There was no significant difference between vessel measurements on MRA and measurements on systolic cine SSFP (p=0.44 for the TOF group and p=0.79 for ARVC group). Measurements on the MRA datasets were significantly larger than those on diastolic SSFP images (p<0.0001).
