PURPOSE OF REVIEW: This review describes the latest advances in cell therapy, biomaterials and 3D bioprinting for the treatment of cardiovascular disease. RECENT FINDINGS: Cell therapies offer the greatest benefit for patients suffering from chronic ischemic and nonischemic cardiomyopathy. Rather than replacing lost cardiomyocytes, the effects of most cell therapies are mediated by paracrine signalling, mainly through the induction of angiogenesis and immunomodulation. Cell preconditioning, or genetic modifications are being studied to improve the outcomes. Biomaterials offer stand-alone benefits such as bioactive cues for cell survival, proliferation and differentiation, induction of vascularization or prevention of further cardiomyocyte death. They also provide mechanical support or electroconductivity, and can be used to deliver cells, growth factors or drugs to the injured site. Apart from classical biomaterial manufacturing techniques, 3D bioprinting offers greater spatial control over biomaterial deposition and higher resolution of the details, including hollow vessel-like structures. SUMMARY: Cell therapy induces mainly angiogenesis and immunomodulation. The ability to induce direct cardiomyocyte regeneration to replace the lost cardiomyocytes is, however, still missing until embryonic or induced pluripotent stem cell use becomes available. Cell therapy would benefit from combinatorial use with biomaterials, as these can prolong cell retention and survival, offer additional mechanical support and provide inherent bioactive cues. Biomaterials can also be used to deliver growth factors, drugs, and other molecules. 3D bioprinting is a high-resolution technique that has great potential in cardiac therapy.

PURPOSE OF REVIEW: To review and prioritize data on pediatric cardiac pacing published during the period of the last 18 months. RECENT FINDINGS: New approaches to preservation of ventricular function in pediatric pacing are based on recent publications confirming major influence of the ventricular pacing site on left ventricular (LV) function and synchrony. Current studies on epicardial vs. transvenous pacing continue to show survival superiority of endocardial leads. Long-term outcome of epicardial pacing may, however, be positively influenced by technical refinements. Recent amendments of the guidelines for cardiac resynchronization therapy (CRT) in adult idiopathic and ischemic cardiomyopathy are likely to influence CRT indications in children. Novel data give interesting insights into implantable cardioverter-defibrillator (ICD) lead survival as well as the use of ICDs in young patients with hypertrophic cardiomyopathy. SUMMARY: Pediatric cardiac pacing and ICD therapy is still a developing field likely to improve with technical refinements, proper lead placement and more specific therapy indications. The current review will give the reader information about recent developments and directions for the future.
