Review
Thirty-eight patients had assessment of pulmonary vein occlusion with the dielectric mapping system and injection of saline as an alternative to contrast. Contrast injection was required to ascertain pulmonary vein occlusion in 31.6% (12 of 38) of subjects and 17.4% (27 of 155) of veins. No contrast was required in the last 13 subjects. In this single center study, a novel mapping-guided cryoablation approach appeared to minimize the use of contrast in pulmonary vein isolation for the treatment of atrial fibrillation.

Review
Newer-generation CT scanners with ultrawide detectors or dual sources offer millisecond image acquisition times and significantly decreased radiation doses compared to historical cardiac CT and CT angiography. This technology is capable of nearly freezing cardiac and respiratory motion. As a result, CT is increasingly used for diagnosing and monitoring cardiac and vascular abnormalities in the pediatric population. CT is particularly useful in the setting of pulmonary vein evaluation because it offers evaluation of the entire pulmonary venous system and lung parenchyma. In this article we review a spectrum of congenital and acquired pulmonary venous abnormalities, including potential etiologies, CT imaging findings and important factors of preoperative planning. In addition, we discuss optimization of CT techniques for evaluating the pulmonary veins.

Review
This review provides an update on the morphology of the sinus venosus defect. It was earlier believed that a 'common wall' separated the right pulmonary veins from the superior caval vein. In the sinus venosus defects, this wall was absent. Current evidence shows that the superior rim of the oval fossa, rather than forming a second septum or representing a common wall, is an infolding between the walls of the caval veins and the right pulmonary veins. The sinus venosus defect is caused by the anomalous connection of one or more pulmonary veins to a systemic vein. However, the pulmonary vein(s) retain their left atrial connections, leading to a veno-venous bridge that allows interatrial shunting outside the oval fossa. True atrial septal defects are located within the oval fossa or in the anteo-inferior buttress, while sinus venosus defects, ostium defects and coronary sinus defects are morphologically distinct from them.

OBJECTIVES
In a living-donor lobectomy, the donor undergoes a right or left lower lobectomy. The surgical procedures for living-donor lobectomy are sometimes influenced by the anatomical variations of the pulmonary vein (PV). The goal of this study was to analyse the PV variations in living donors and to review the influence of these variations on the surgical procedures used.
METHODS
Between June 2008 and September 2018, 154 living donors underwent right or left lower lobectomy. The PV variations were analysed using 3-dimensional computed tomography (3D-CT), and the surgical management of these variations was reviewed.
RESULTS
Among 154 donors, 21 PV variations that could influence the surgical procedure for a right lower lobectomy were found in 19 (12.3%) donors, whereas no such variations for a left lower lobectomy were found. Detected PV variations were dorsal branch of the right upper PV (n = 12), middle PV draining into the right lower PV (n = 6) and the superior segment branch of the right lower PV draining into the right upper PV (n = 3). Among 96 donors undergoing right lower lobectomy, 9 (9.4%) donors had PV variations that could influence the surgical procedure. In 2 donors, sparing of PV branches with multiple vascular clamps was required. Pulmonary venoplasty was not required in any donor, whereas pulmonary venoplasty in recipient surgery was required in 4 recipients. There were no complications related to the surgical procedures performed on the PV.
CONCLUSIONS
Living-donor lobectomy was performed safely owing to the preoperative evaluation of PV on 3D-CT and the use of appropriate surgical approaches to PV.
