Balloon angioplasty in the treatment of pulmonary valve stenosis and coarctation of the aorta

Abstract

When balloon angioplasty of the pulmonary valve was attempted in 42 children, aged 1 day to 19 years (mean, 3.1 years), immediate relief of pulmonary stenosis was achieved in 37 cases. In two groups, angioplasty was not uniformly successful: these included (1) two neonates and (2) three out of seven children with dysplastic pulmonary valves, who had an unsuccessful early result. Long-term (>1-year) follow-up of 28 successful cases supports the contention that balloon angioplasty provides effective long-term relief of pulmonary valve stenosis and that it should be considered the treatment of choice for this lesion. The results of angioplasty were also studied in 36 children who underwent this procedure to treat coarctation of the aorta (involving 21 native and 15 recurrent lesions). Angioplasty effectively relieved the obstruction in 30 cases (17 native and 13 recurrent lesions). In the six unsuccessful cases, poor hemodynamic results were due to age (three failures occurred in children less than 2 years old), tubular hypoplasia of the aorta (in one case), and the use of an undersized angioplasty balloon (in four cases, the diameter of the balloon was > or =3 mm less than that of the aortic isthmus). The 36 patients had two majo...Continue Reading

Aortic Coarctation

Aortic coarctation is a congenital condition characterized by narrowing of the aorta. Discover the latest research on this disease here.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.
