Abstract
Balloon pulmonary valvuloplasty is a safe and effective treatment for isolated pulmonary valve stenosis. Several balloon catheters are available for this procedure in neonates and infants. However, obtaining additional vascular access for the double-balloon technique in this population is troublesome, and tricuspid valve injury is a concern. We used a TMP PED balloon catheter to perform valvuloplasty in 2 infants with isolated pulmonary valve stenosis. This thin-walled, relatively large 12-mm balloon catheter can be delivered through a small-diameter sheath. In both cases, the transpulmonary pressure gradient was reduced without causing any valvular or vascular injuries. Neither patient had recurrent pulmonary valve stenosis. Together, these cases highlight the suitability and feasibility of using the 12-mm TMP PED balloon catheter for treating young infants with valvular stenosis.
期刊介绍：
For more than 45 years, the Texas Heart Institute Journal has been published by the Texas Heart Institute as part of its medical education program. Our bimonthly peer-reviewed journal enjoys a global audience of physicians, scientists, and healthcare professionals who are contributing to the prevention, diagnosis, and treatment of cardiovascular disease.
The Journal was printed under the name of Cardiovascular Diseases from 1974 through 1981 (ISSN 0093-3546). The name was changed to Texas Heart Institute Journal in 1982 and was printed through 2013 (ISSN 0730-2347). In 2014, the Journal moved to online-only publication. It is indexed by Index Medicus/MEDLINE and by other indexing and abstracting services worldwide. Our full archive is available at PubMed Central.
The Journal invites authors to submit these article types for review:
