However, redo procedures remain particularly challenging, with surgical results still inferior to those of primary operations. The complexity arises from altered anatomy, dense adhesions, and increased risks of injury to vital structures. Careful surgical planning is therefore indispensable, and four strategic steps are especially critical. First, meticulous preoperative assessment with contrast-enhanced computed tomography is required to delineate the spatial relationship between the heart, great vessels, and sternum. Second, the optimal approach to intrapericardial access must be determined, including whether cardiopulmonary bypass should be instituted prior to median sternotomy. Third, safe and deliberate dissection of adhesions surrounding the heart and great vessels is essential to avoid catastrophic complications. Finally, effective organ protection strategies, particularly for the brain and myocardium, are paramount to ensure favorable outcomes.

This review focuses on the hepatokine Fetuin-A and the post-translational modification N-myristoylation in HF. Regarding Fetuin-A, we first demonstrated that circulating Fetuin-A levels were significantly lower in HF patients than in control subjects without structural heart disease. This reduction was associated with hepatic hypoperfusion. In a prospective study of 202 HF patients who underwent cardiopulmonary exercise testing, the combination of lower Fetuin-A and impaired exercise tolerance was independently associated with increased risk of cardiac events, suggesting that Fetuin-A could serve as a novel mediator of cardiac-hepatic-peripheral interaction. Regarding N-myristoylation, expression of N-myristoyltransferase 2 (NMT2) was significantly reduced in failing hearts. Cardiac-specific NMT2 knockdown exacerbated cardiac dysfunction, whereas AAV9-mediated NMT2 gene transfer attenuated cardiac remodeling and HF. Click chemistry-based proteomics identified MARCKS as a crucial substrate, and N-myristoylation of MARCKS prevented pathological hypertrophy by promoting its membrane localization, thereby suppressing CaMKII-HDAC4 signaling.
