Cardiac lead perforation: Mechanisms, detection, and therapeutic approaches

Cardiac lead perforation is an infrequent but serious complication of cardiac implantable electronic devices, with possibly lethal consequences if left untreated. Because of its very varied clinical appearance and lack of established criteria, perforation still presents diagnostic and therapeutic hurdles despite continuous improvements in lead design and insertion procedures. This review summarizes current research on the processes, risk factors, and clinical range of lead perforation. Thin myocardial walls, especially at the right ventricular apex; active-fixation leads; and operator-dependent elements, such as lead placement and torque, are important anatomic and procedural contributions. Steroid usage, low body mass index, and female sex all increase risk. A strong index of suspicion is often required for prompt diagnosis because presentations vary from asymptomatic instances to severe tamponade. Device interrogation must be integrated with imaging modalities, particularly computed tomography and echocardiography, which each have unique benefits based on the clinical setting, to achieve accurate detection. From cautious observation in stable patients to immediate percutaneous or surgical intervention in unstable or worsening situations, management approaches are highly customized. New technologies, including subcutaneous implantable cardioverter-defibrillators and leadless pacemakers, have the potential to lower the incidence of perforations, but they also present new difficulties that need to be further investigated. Importantly, the lack of consistent diagnostic standards hinders study/ comparability and postpones the creation of guidelines. Standardizing diagnostic criteria, establishing multicenter prospective registries, developing machine learning-based risk stratification tools, and conducting clinical trials to inform the treatment of asymptomatic or delayed perforations are among the top goals for the future. To improve patient outcomes and advance clinical practice, international cooperation and uniform reporting standards are crucial.
