This can be minimized by appropriate drug therapy and, specifically, early recanalization of the infarct-related vessel by means of thrombolysis or primary angioplasty. The recent introduction of balloon angioplasty provides yet another palliative option for young symptomatic infants presenting prior to the optimal age for primary repair. Percutaneous balloon angioplasty for recoarctation of the aorta is immediately effective in reducing pressure gradients. Angioplasty catheters with a total balloon length of 20 mm were chosen to avoid injury to the mitral valve during inflation. Now that closure methods using a catheter, like balloon angioplasty, are confronting common anomalies, they are occupying more of the energies of the pediatric cardiologist. Sequential balloon angioplasty then permitted gradual enlargement of the newly created channel, and subsequent placement of stents established a persistently wide venoatrial communication. Coronary bypass grafts have been utilized, and in rare instances, balloon coronary angioplasty and thrombolytic therapy have been attempted. Two patients developed transient complete heart block following balloon dilation or angioplasty of the pulmonary valve or pulmonary artery via a left subclavian venous approach. Balloon angioplasty (balloon diameter 15 mm) of the stenosis in the left pulmonary artery was unsuccessful. In individual cases, nonetheless, localized stenoses appeared to be effectively dilated as evidenced by the angiographic findings after balloon angioplasty. Three of these 5 patients were redilated successfully by second balloon angioplasty. Aortic constriction was treated with balloon angioplasty (6), surgery then balloon angioplasty (4), or surgery alone (1). Complications with balloon angioplasty were need for transfusions in two and femoral arterial compromise in two. In three patients, the tight obstruction was dilated with coronary angioplasty catheters. See all examples of angioplasty These examples are from corpora and from sources on the web.
