“…While acute lead perforation into the left ventricle cavity is a relatively frequent complication reported in various other studies, 7 the septal tunnel created by a lumenless lead such as SelectSecure 3830 is small and is considered to close spontaneously without detectable shunting on postprocedural echocardiography. 8 In this case, the contrast agent injected into the septum was unexpectedly able to exit through the route by the initial lead perforation. The contrast agent flowed only into the right ventricle, but not into the left ventricle.…”

“…The target site for the lead deployment was identified as previously described. 11 As the lead was advanced into the septum, the notch of the paced QRS in lead V 1 moved from the nadir to the end of the QRS, resulting in right bundle branch block pattern and concomitant gradual increase in unipolar pacing impedance (≥500 Ω). Four initial fast turns, and then 3 more slow turns, were performed to position the lead at the left bundle.…”

“…As shown in Figure 3 , selective LBB capture was confirmed by the presence of a right bundle branch block pattern, V 6 –V 1 R-wave interpeak interval of 44 ms, and a constant (at high and low pacing output) R-wave peak time of 67 ms in V 6 . 11 , 12 Figure 3 Selective left bundle branch pacing (LBBP) was successfully performed after extraction of a His bundle pacing lead. Electrogram shows selective LBBP, indicated by the presence of right bundle branch delay pattern, V 6 –V 1 R-wave interpeak interval of 44 ms, a pacing stimulus–to–peak R wave (stim-LVAT) of 67 ms, and isoelectric stimulus to QRS interval.…”
“…A popular article type is our Perspectives in Contrast, which features 2 opposing views on therapeutic or diagnostic topics. In the February issue, Dr Jan De Pooter 4 and Drs Shunmuga Sundaram Ponnusamy and Pugazhendhi Vijayaraman 5 defended their favored type of lead for physiological pacing—either stylet-driven 4 or lumenless. 5 …”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
