Cardiovascular surgery needs better biomaterials that mimic native tissues. This paper reviews current biomaterials, their interactions within the circulatory system, infection risks, and future developments for improved biocompatibility.

Area of Science:

  • Biomaterials Science
  • Cardiovascular Surgery
  • Biocompatibility Research

Background:

  • Current biomaterials in cardiovascular surgery often lack the essential characteristics of native tissues.
  • The integration of artificial materials into the circulatory system triggers complex biological responses.

Purpose of the Study:

  • To review existing biomaterials used in cardiovascular surgery.
  • To discuss the biological reactions, infection risks, and prevention strategies associated with these biomaterials.
  • To explore future directions in biomaterial development for enhanced biocompatibility.

Main Methods:

  • Literature review of biomaterials in cardiovascular applications.
  • Analysis of host-biomaterial interactions.
  • Discussion of infection control and future research trends.
