This approach avoids direct suturing to the pulmonary vein wall by covering the opened vein with autologous or xenogeneic tissue (left atrial appendage, pericardium, or atrial wall). A total of 13 pulmonary veins were reconstructed. Restenosis was evaluated using follow-up computed tomography, and 5-year patency was estimated by Kaplan\u2013Meier analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>All patients underwent successful repair without perioperative complications. Covering materials included the left atrial appendage (n\u2009=\u20093), bovine pericardium (n\u2009=\u20092), autologous pericardium (n\u2009=\u20091), and atrial wall flap (n\u2009=\u20091). During a mean follow-up of 62.5\u2009\u00b1\u200946.5\u00a0months, restenosis occurred in 2 of 13 veins (15.4%) four months after surgery, both initially classified as stenotic lesions.
