Comparison of risks and short- and long-term results of balloon dilatation versus surgical treatment for pulmonary and aortic valve stenosis and restenosis and coarctation and recoarctation of the aorta.

Balloon valvuloplasty and angioplasty have become accepted alternatives to surgery for valvar stenosis and coarctation of the aorta. Balloon dilation avoids a potentially painful operation, the long postoperative recovery, and at the same time offers substantial cost savings. However, such advantages are meaningless if the safety of the interventional procedure does not match or surpass the results of conventional surgery. This review summarizes a number of studies that compare the natural history of surgical therapy with that of balloon pulmonary and aortic valvuloplasty and balloon coarctation angioplasty. It appears that, regardless of age, balloon valvuloplasty is preferable to surgical valvotomy. For both aortic stenosis and coarctation of the aorta, balloon valvuloplasty and surgical valvotomy produce comparable relief of the hemodynamic obstruction. However, because the length of follow-up after the balloon angioplasties has been short, the actual risk of developing severe aortic regurgitation (postaortic valvuloplasty) and aortic aneurysms (postcoarctation angioplasty) has not been trivial, a large prospective follow-up of both of these interventional procedures will be mandatory before either can be judged superior to surgical therapy.

Occlusion of an aberrant artery to a pulmonary sequestration using a duct occluder.

This report describes a female infant with a rare chromosome defect, del. 12 (q22-24.1), who has severe pulmonary valve stenosis, an atrial septal defect, and a small muscular ventricular septal defect. At 4 months of age a balloon pulmonary valvuloplasty was performed in the cardiac catheterization laboratory. During the procedure, a large aberrant artery from the aorta to a sequestration of the right lower lobe of lung was found. The flow-off from the sequestration was into a dilated left atrium. The single artery supplying the sequestration was successfully occluded using an Amplatzer Duct Occluder device. There were no complications and the infant remains well at 1-year follow-up.

[Percutaneous valvuloplasty: a decade of continuous progress].

Percutaneous balloon valvuloplasty is an interventional procedure designed to treat valve stenosis. The indications, techniques and results depend on the valve being opened. It is currently the treatment of choice for pulmonary valve stenosis. It is an excellent alternative to surgery for mitral stenosis in patients with mobile valves and little abnormality of the subvalvular apparatus. In aortic stenosis it constitutes a gratifying palliative procedure in older patients at high surgical risk. Longer observation is needed to better appreciate the results and indications of balloon valvuloplasty.

[Quadricuspid pulmonary valve with valvular stenosis and regurgitation identified by transthoracic echocardiography: a case report].

A 74-year-old man was admitted to our hospital complaining of dyspnea. Parasternal transthoracic echocardiography showed a quadricuspid pulmonary valve above the aortic valve and a hypoplastic accessory cusp between the right and left cusps of the pulmonary valve. The pulmonary valve ring diameter was normal (26 mm) but the transvalvular peak velocity was 3.5 m/sec, suggesting a pressure gradient of 49 mmHg across the pulmonary valve. The pulmonary valve had thickening and decrease in mobility of the leaflets without complete closure during diastole, and severe pulmonary regurgitation was present. Heart failure was treated successfully with digitalis and diuretics. Quadricuspid pulmonary valve is difficult to identify using transthoracic echocardiography because of the anatomical features. In this case, the dilated main pulmonary artery caused the pulmonary valve orifice to shift anteriorly, allowing visualization of the short-axis view of the pulmonary valve.
