Objectives: In the surgical treatment of pulmonary atresia with intact ventricular septum, the size of the tricuspid valve annulus (as measured by z-scores) has emerged as a significant factor in deciding which repair to perform. Various tricuspid valve annulus z-scores are reported as “cutoffs” for successful biventricular repair. We aimed to determine whether the use of different z-score data sets contributed to the gross variation in “cutoffs” for successful biventricular repair reported in…

Optimal Use of Z-Scores to Preserve the Pulmonary Valve Annulus During Repair of Tetralogy of Fallot

Recommendations to perform valve-sparing surgery in pulmonary annuli as small as −4 may not be warranted and future papers should record “cutoffs” employing recommended z-score data set.

Pulmonary Atresia with Intact Ventricular Septum: Midterm Outcomes from a Multicenter Cohort

Right ventricular coronary dependency and left, but not right, coronary atresia significantly worsens transplant-free survival and in a contemporary multicenter cohort of patients with PAIVS, favorable survival outcomes are observed.

Fetal Echocardiographic Predictors of Postnatal Surgical Strategies in Critical Pulmonary Stenosis or Atresia with Intact Ventricular Septum: A Meta-Analysis

Commonly obtained fetal echocardiographic measurements have strong associations with treatment pathway choice for patients with PSAIVS, and greater RV growth appears to favor biventricular repair, whereas patients with VCC almost invariably undergo univocentular palliation.

Possible impairment of surgical decision making and confounded outcome in Fontan surgery by Nakata Index

Nakata index systematic error may impair surgical decision making and confound outcome measurement in Fontan surgery, and continued use of the Fontan index may have similar implications for other congenital heart lesions.

Fetal Cardiac Intervention for Pulmonary Atresia with Intact Ventricular Septum: International Fetal Cardiac Intervention Registry

A possible benefit to fetal therapy for PAIVS/PS cases evaluated from January 2001 to April 2018 is suggested, though rates of technically unsuccessful procedures and procedure-related complications, including fetal loss were substantial.

Pulmonary Atresia With an Intact Ventricular Septum: Preoperative Physiology, Imaging, and Management

While transthoracic echocardiography allows for detailed delineation of the cardiac anatomy, additional imaging modalities such as computed tomography, magnetic resonance imaging, and catheterization may be necessary to further outline features of the heart anatomy, specifically coronary artery anatomy.

Perioperative and Anesthetic Considerations in Pulmonary Atresia With Intact Ventricular Septum

The perioperative and anesthetic management of patients with PA/IVS will be discussed and the challenges in management will be highlighted.

Initial RV dimensions in infants with CHD and a hypoplastic RV can be quantified by CT and are substantially smaller than those in infantsWith tetralogy of Fallot.



Pulmonary atresia with intact ventricular septum: management of, and outcomes for, a cohort of 210 consecutive patients

The outcomes for patients born with pulmonary atresia with intact ventricular septum have improved over time, albeit that careful initial management, and better selection, is still indicated for those planned to undergo biventricular repair.

Predictors for biventricular repair in pulmonary atresia with intact ventricular septum.

Decompression of the RV as an initial surgical procedure improves the possibility of achieving biventricular repair with good long-term results, however, morphological factors such as right ventricular size and the absence of coronary fistulae are significant predictors for bivocentular repair.
