Background:

• Cardiac disease is a major global cause of mortality.
• Conduction system disturbances can lead to heart failure or arrest, necessitating implantable cardiac rhythm management devices (ICRMDs).
• Current ICRMDs, while improved, face limitations related to lead placement and location.

Purpose of the Study:

• To review current strategies for selecting placement sites for pacemakers, implantable cardioverter defibrillators (ICDs), and cardiac resynchronization therapy (CRT) devices.
• To discuss technological advancements aimed at improving ICRMD therapy outcomes.
• To highlight the potential of leadless technology in overcoming current limitations.

Main Methods:

• Literature review of state-of-the-art placement site selection for cardiac devices.
• Analysis of existing limitations in transvenous lead placement.
• Exploration of novel approaches like multi-site pacing and leadless solutions.

Main Results:

• Lead placement and location are significant factors affecting pacemaker therapy efficacy.
• Various approaches, including multi-site pacing, are being developed to address lead-related challenges.
• Leadless technologies represent a promising advancement in ICRMDs.

Conclusions:

• Optimizing lead placement is crucial for effective cardiac device therapy.
