Background: Primary cardiac tumors (PCT), such as myxoma, are rare and predominantly benign. Angiofibroma tumors are an extremely rare subtype of PCT, reported in less than ten cases. In this study, we presented a mixed tumor of myxoma and angiofibroma for the first time in the human heart.

Artificial intelligence (AI) holds promise in enhancing outcome predictions for congenital cardiac surgery. This study aims to systematically review the utilization of AI in predicting post-operative outcomes in this population.

Article Synopsis
- Intraoperative Hypotension (IOH) is a significant risk during surgeries, and using Artificial Intelligence (AI) to predict IOH could improve patient safety and outcomes.
- A systematic review and meta-analysis were conducted, analyzing 43 studies that evaluated AI models, especially focusing on the Hypotension Prediction Index (HPI) and other AI methods across various surgical types.
- Results indicated that HPI had a strong predictive performance (AUROC of 0.89), significantly reducing the duration of hypotension, while non-HPI models also showed promise with an AUROC of 0.79.
The global organ donation crisis continues to escalate despite advancements in medical procedures. Uncont-rolled donation after circulatory death provides an alternative method to increase the donor pool, especially for kidney transplants. This case study from Iran offers insights into the complex, yet essential, facets of organ procurement under uncontrolled donation after circulatory death protocols.

Materials And Methods: In this follow-up study, we followed heart transplant recipients for 1 year to study patient survival, ejection fraction, adverse events, and organ rejection.
Article Synopsis
- Heart transplant is the preferred option for patients with severe heart failure who don't respond to other treatments, but there is a shortage of suitable donors.
- The article discusses a 43-year-old woman who urgently needed a heart transplant and received a heart from a 50-year-old donor who had a history of coronary artery disease but was otherwise suitable.
- Follow-up after one year showed no complications, suggesting that using "marginal hearts" (hearts from less-than-ideal donors) can be viable, although more research is needed to explore these findings further.
