Congenital heart diseases that cause obstruction of the right ventricular outflow tract are often difficult to diagnose. We report the case of a 49-year-old man who presented with long-standing shortness of breath on exertion. Imaging revealed right ventricular outflow tract obstruction caused by a double-chambered right ventricle, and he was referred for surgical correction. This case emphasizes both the detailed perioperative evaluation that is needed when diagnosing adults who present with manifestations of congenital heart disease and a method of successful surgical correction that resulted in symptom resolution.

Right ventricular outflow tract surgery was originally confined to transannular patching, in the belief that pulmonary regurgitation was well tolerated. Because follow-up evaluations revealed the deleterious effects of pulmonary regurgitation, surgery today aims to spare or replace the valve. Available replacement devices have short lifetimes, considering growth mismatch in children. We hypothesize that oversizing the right infundibulum anticipates growth and that a squeezed prosthesis can complete the expansion process.
The No-React® Injectable BioPulmonic Valve is designed for right infundibular surgery in adults, and hundreds of implants have shown promising results. We used this device for surgery in babies, with the …

Coronary spasm during coronary angiography for vasculopathy in children can be prevented by the intracoronary administration of nitroglycerin. We reviewed the anesthesia and catheterization reports and charts for pediatric transplant recipients who underwent angiography from 2005 through 2010. Correlation analysis was used to study the relation of post-injection systolic blood pressure (SBP) to nitroglycerin dose. Forty-one angiographic evaluations were performed on 25 patients (13 male and 12 female). Mean age was 9.9 ± 3.2 years (range, 3.3–16.1 yr). The mean total dose of nitroglycerin was 2.93 ± 1.60 µg/kg (range, 1–8 µg/kg).
There was a significant drop between the baseline …
