Availability of long stents allowed a single\u2010stent strategy (hybrid in 14) in 79% and elective overlapping stents only in 21%. 79\u2009mm stent length was more frequently used. Additional stents to bail\u2010out embolization, caudal migration, and fabric leak were required in 22%. Median stent shortening was 9%, and recoil was negligible (median 2%). Procedural success was 98%; two embolizations required surgery. 73.5% had no residual shunt at 1\u2010year transesophageal echocardiography. At a median follow\u2010up of 21 months (2\u201341 months), residual leak warranted two reinterventions. Asymptomatic intraluminal stent thrombosis was noted in 10.2%, and minor insignificant fabric leak in 11.2%.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>ZephyrCS is safe, feasible, and effective for SVD closure, with acceptable mid\u2010term outcomes.
