Entirely subcutaneous defibrillator and complex congenital heart disease: Data on long-term clinical follow-up

Figure 1 A new transeptal endocardial lead was implanted in the left ventricle and the atrial septal defect was thereafter successfully closed with an occlude device. A: Subcutaneous implantable cardiac defibrillator and endocardial pacing system in a patient post Mustard operation; B: Patient with ASD and dilatative DCM who previously underwent left ventricle lead implant; C: Patient with Eisenmenger syndrome. ASD: Atrial septal defect; DCM: Dilatative cardiomyopathy.

Figure 2 Hybrid implant (subcutaneous implantable cardiac defibrillator and epicardial pacing). The patient developed severe tricuspid regurgitation related to the endocardial lead previously implanted.

Figure 3 Summary of the events during follow-up according to different anatomic background. TOF: Tetralogy of Fallot; VSD: Ventricular septal defect; TGA: Transposition of great arteries; DILV: Double inlet left ventricle; ASD: Atrial septal defect; HLVS: Hypoplastic left ventricle syndrome; I: Infection; IS: Inappropriate shock; AS: Appropriate shock; GC: Generator change; LF: Last follow-up; DCM: Dilatative cardiomyopathy.
