Methods
Patients, in which LBBAP was attempted for bradycardia or heart failure
pacing indications, were prospectively enrolled at the Ghent University
Hospital. LBBAP was attempted with two different systems: 1/ LLL with
fixed helix (SelectSecure 3830, Medtronic, Inc) delivered through a
preshaped sheath (C315His Medtronic) and 2/ SDL with extendable helix
(SoliaS60, Biotronik, SE & CO) delivered through a new delivery sheath
(Selectra 3D, Biotronik).
