Predicting Pediatric Pulmonary Vein Stenosis Outcomes Using Data Acquired During a Cardiac Catheterization
Predicting Pediatric Pulmonary Vein Stenosis Outcomes Using Data Acquired During a Cardiac Catheterization
This is a prospective, single center study which applies a standardized, comprehensive
 catheterization assessment to patients with a known or suspected diagnosis of pulmonary vein
 stenosis (PVS) who are undergoing a cardiac catheterization at Boston Children's Hospital. As
 part of the assessment, each pulmonary vein will undergo angiography (pictures using moving
 x-rays and contrast dye), intravascular ultrasound (IVUS; pictures of the vein wall using a
 catheter inside the vein), pressure assessment and compliance testing. The status of each
 pulmonary vein will then be assessed 12 months after the catheterization (i.e. no disease,
 severe disease, etc.). Using statistics, the investigators will determine which patient and
 vein characteristics (obtained at the of catheterization) can predict whether or not a
 pulmonary vein will have disease. The investigators hypothesize that this comprehensive,
 standardized, invasive assessment of pediatric intraluminal PVS can predict vein outcome.
Inclusion Criteria:

 -  Pediatric patients undergoing cardiac catheterization for the indication of known or
 suspicion for intraluminal pulmonary vein stenosis.

 Exclusion Criteria:

 -  Hemodynamically unstable patients as determined by the patient care team.
