Branch pulmonary artery stenosis after arterial switch operation: The effect of preoperative anatomic factors on reintervention.
We hypothesized that preoperative patient characteristics and branch pulmonary artery (PA) size might influence the rate of postoperative branch PA reintervention in patients with transposition of the great arteries who undergo the arterial switch operation (ASO). ⋯ Branch PA reintervention was common and often required surgical or catheter-based reinterventions after ASO. PA branch diameters became significantly smaller after ASO. Smaller preoperative branch PA predicted late branch PA reintervention, indicating a smaller margin of geometrical tolerance to this effect.

Systemic ventricular assist device support of the Fontan circulation yields promising outcomes: An analysis of The Society of Thoracic Surgeons Pedimacs and Intermacs Databases.
Outcomes of ventricular assist device (VAD) support in patients with Fontan circulatory failure (or failing Fontan physiology) are largely unknown. ⋯ This is the largest reported analysis of systemic VAD support of Fontan patients. VAD support of the Fontan circulation is becoming more frequent. This analysis demonstrates that VAD use in this growing population can yield promising outcomes.
