Key result
Combined balloon angioplasty and valvuloplasty successfully reduced the pressure gradient to 0 mmHg and altered the coarctation diameter from 2.1 to 5.5 mm in a 1-month-old infant.
Why the study?
Does combined balloon angioplasty and valvuloplasty improve hemodynamics in an infant with coexisting coarctation of the aorta and aortic stenosis?

Does combined balloon angioplasty and valvuloplasty improve hemodynamics in an infant with coexisting coarctation of the aorta and aortic stenosis?
Combined balloon angioplasty and valvuloplasty can successfully relieve pressure gradients in infants with coexisting coarctation of the aorta and aortic stenosis.
The patient was a 1-month-old male infant. Echocardiography showed left ventricular hypertrophy with coarctation of the aorta (CoA) and aortic valve stenosis (AVS). Left ventricular systolic function was poor. At catheterization, the gradient of AVS was 25 mmHg and the annulus size of the aortic valve was 7 mm. There was a CoA measuring 2.1 mm in diameter. Balloon valvuloplasty of the CoA was then performed using the same balloon; the pressure gradient decreased to 0 mmHg, and CoA diameter decreased from 2.1 to 5.5 mm.

Ohkubo et al. (1998) conducted a case report in Coarctation of the aorta and aortic valve stenosis (n=1). Combined angioplasty and valvuloplasty was evaluated. Combined balloon angioplasty and valvuloplasty successfully reduced the pressure gradient to 0 mmHg and altered the coarctation diameter from 2.1 to 5.5 mm in a 1-month-old infant.
