Novel autopsy and genetic findings in an acardiac twin: case report and literature review.

Twin reversed arterial perfusion (TRAP) sequence is a rare complication of monochorionic twinning whereby a donor twin perfuses an acardiac twin via aberrant vascular anastomoses. The resulting paradoxical retrograde blood flow supplying the acardiac twin is oxygen-poor, leading to some of the most severe malformations encountered in humans. Though the first descriptions of acardiac twins date back to at least the 16 century, the pathophysiologic processes which underpin the development of TRAP sequence are still being elucidated.

Successful medical group integration: it's about more than the numbers.

Key aspects of integrating a medical group into a health system include: Performing due diligence. Developing a culture of trust. Onboarding new physicians and groups.
