The Micra™ leadless pacemaker (Medtronic, Minneapolis, MN, USA) is indicated for the management of symptomatic bradycardia and advanced heart block. However, the safety of this procedure during pregnancy has not been studied. Here, we present a unique case of Micra™ leadless pacemaker implantation (MLP) in a 31 weeks pregnant patient with intermittent complete heart block who presented with multiple syncopal episodes. The patient underwent an MLP implantation with <40 mGy radiation exposure (about 0.6 min of total fluoroscopy time), which is deemed a negligible dose of radiation exposure during pregnancy. Her subsequent hospital course was uneventful, and she was safely discharged home and was able to continue her pregnancy and delivery without further syncopal episodes or incidence of heart block.

Background: Guideline-recommended strategies to interrupt chronic anticoagulation with warfarin or direct oral anticoagulants (DOAC) during the perioperative period of cardiac implantable electronic device (CIED) surgery differ worldwide. There is uncertainty concerning the benefits and harms of interrupted and uninterrupted anticoagulation in patients undergoing CIED surgery.
Objectives: To assess the benefits and harms of interrupted anticoagulation (IAC) with either warfarin or DOAC in the perioperative period of CIED surgery versus uninterrupted anticoagulation (UAC), with or without heparin bridging, during an equivalent time frame, for CIED surgery.

Background: Cardioneuroablation (CNA) is a new approach to treat reflex syncope and functional bradyarrhytmias caused by autonomic imbalance. We report our experience using CNA.
Method: From September 2022 to July 2023, we took care of 21 patients (mean age 42 ± 21 years; 62% male) affected by reflex syncope or functional bradyarrhythmias.

Background: Patients after transcatheter pulmonary valve implantation (TPVI) are at increased risk for infective prosthetic valve endocarditis. Diagnosis of infective endocarditis (IE) following TPVI is particularly difficult due to impaired visualization of the transcatheter pulmonary valve (TPV) with echocardiography [Delgado V, Ajmone Marsan N, de Waha S, Bonaros N, Brida M, Burri H, et al. 2023 ESC guidelines for the management of endocarditis.

Background: Coronary sinus (CS) lead placement in persistent left superior vena cava (PLSVC) cases is challenging because of the poor backup force of the guiding catheter within the enlarged CS. Active fixation Quadripolar leads (Attain Stability™ Quad 4798, Medtronic) can expand choice to CS branches with limited access; however, no cases of anchoring to the main body of the CS have been published to date.
Case Summary: We describe a case of cardiac resynchronization therapy pacemaker upgrade in a 79-year-old female who developed pacing-induced cardiomyopathy after pacemaker implantation via the right superior vena cava (SVC) for atrioventricular block eight years ago wherein PLSVC was revealed during the procedure.

Background: Intravascular lithotripsy (IVL), that generates shockwaves through spark gap discharge between emitters, has been increasingly used to treat severely calcified coronary artery lesions. However, there is a question as to whether IVL has no electrical effects on endocardial tissues or cardiac implantable devices (CIEDs).
Aims: The aim of this study was to investigate the effects of IVL-induced intracardiac potentials on cardiac electrophysiology and CIEDs.
