Translational Strategies for Developing and Evaluating Transcatheter Devices in Swine Heart Failure Models.

Area of Science:

• Cardiovascular Research
• Medical Device Development
• Preclinical Animal Models

Background:

• Therapeutic transcatheter devices are crucial for cardiovascular diseases.
• Precise preclinical models and robust evaluation methods are essential for device development.
• Swine models are widely used for cardiovascular research due to physiological similarities to humans.

Purpose of the Study:

• To review key aspects of preclinical evaluation for transcatheter cardiovascular devices.
• To discuss swine heart failure models, echocardiographic methods, and implantation techniques.
• To ensure reliability in preclinical data and facilitate successful clinical translation of devices.

Main Methods:

• Review of common swine heart failure models (pacing-induced, volume overload, ischemic).
• Analysis of echocardiographic techniques (transthoracic, transesophageal, intracardiac, epicardial).
• Evaluation of transcatheter device implantation approaches in swine (trans-atrial, trans-apical, trans-septal, trans-right pulmonary).

Main Results:

• Different swine heart failure models offer distinct pathological conditions for device testing.
• Echocardiography provides essential structural and functional assessments, aiding procedural guidance and outcome evaluation.
• Various implantation approaches present unique advantages and challenges, requiring careful consideration of anatomical relationships.

Conclusions:

• A comprehensive understanding of swine models, echocardiography, and implantation techniques is vital for successful transcatheter device development.
• Optimizing preclinical evaluation ensures the safety and efficacy of cardiovascular devices.
• This review provides a framework for refining catheter-based interventions and improving clinical translation.
