Severe heart and great vessel injuries were a fatal traumatic entity. How to improve the survival rate of these victims still was a challenge to date. This paper included： the pathogenesis and resuscitation of commotio eordis ; traumatic pericardial rupture associated with heart luxation and/or diaphragmatocele in pericardial cavity; indication selection of emergency room thoracotomy for severe heart injury and traumatic aortic disruption treated with endovascular stent graft. For the purpose of increasing our recognition of the severe trauma and making the early diagnosis and management as early as possible. The main relative references published in recently 5 years were reviewed.
The study of tissue engineering heart valves is one of the focus about cardiovascular surgery and is developing. Especially acellular tissue engineering heart valves have many advantages in low immunogenicity,non cytotoxicity,recellularation,excellent bionics,durability etc.Therefore, the study of acellular tissue engineering heart valves is becoming the important direction of future development about valves studies. Some development about it is reviewed.
