Intracardiac echocardiography was used as a guide during interventricular septum puncture for left ventricular lead positioning in a patient undergoing cardiac resynchronization therapy.
Case Report (n=1)
Intracardiac echocardiography may serve as a guide for interventricular septum puncture during CRT when standard coronary sinus access is not possible.
Cardiac resynchronization (CRT) is a clinically proven therapy in terms of quality of life and mortality for selected patients with heart failure and left ventricular dyssynchrony.1 The coronary sinus is the most commonly used access for left ventricle (LV) lead positioning in CRT. However, in 5–10% of patients, this approach is not possible because of anatomical variations.2 Surgical epicardial implantation is considered a valid alternative in such situations, but it is not exempt from mortality and morbidity, with formal contraindication in high-risk patients.
Doblado-Calatrava et al. (Sat,) conducted a case report in Heart failure and left ventricular dyssynchrony (n=1). Intracardiac echocardiography-guided interventricular septum puncture was evaluated. Intracardiac echocardiography was used as a guide during interventricular septum puncture for left ventricular lead positioning in a patient undergoing cardiac resynchronization therapy.
