Abstract:
Transcatheter aortic valve implantation (TAVI) is currently performed through an alternative access in 15% of patients. The transapical access is progressively being abandoned as a result of its invasiveness and poor outcomes. Existing data does not allow TAVI operators to favour one access over another - between transcarotid, trans-subclavian and transaortic - because all have specific strengths and weaknesses. The percutaneous trans-subclavian access might become the main surgery-free alternative access, although further research is needed regarding its safety. Moreover, the difficult learning curve might compromise its adoption. The transcaval access is at an experimental stage and requires the development of dedicated cavo-aortic crossing techniques and closure devices.

Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...

Null and Alternative Hypotheses
The null hypothesis, denoted by H0 is a statement of no difference between the variables—they are not related. This can often be considered the status quo. As a result if you cannot accept the null, it requires some action.
The alternative hypothesis, denoted by H1 or Ha, is a claim about the...
