RT Journal Article T1 Leadless pacemaker implantation with hybrid image mapping technique in a congenital heart disease case A1 Martínez Sande, José Luis A1 González Melchor, Laila A1 García Seara, Francisco Javier A1 Rodríguez Mañero, Moisés A1 Fernández López, Xesús Alberte A1 González Juanatey, José Ramón K1 Congenital heart disease K1 Electroanatomical mapping system K1 Leadless pacemaker K1 Sinus venosus atrial septal defect K1 Ultrasound intracar- diac imaging catheter AB Sinus venosus atrial septal defect (SVASD) is an interatrial communication caused by a deficiency of the common wall between the superior vena cava and the right-sided pulmonary veins. Implantation of a conventional pacemaker in this setting can be challenging. We report the feasibility of leadless pacemaker (LPM) implantation assisted by imaging integration and electroanatomical mapping PB Elsevier YR 2021 FD 2021 LK http://hdl.handle.net/10347/27769 UL http://hdl.handle.net/10347/27769 LA eng NO HeartRhythm Case Reports 12 (2021) 797-800. https://doi.org/10.1016/j.hrcr.2021.07.004 DS Minerva RD 24 abr 2026
