MRI of human heart
Artificial heart ready for human trials.
French company CARMAT have announced that their artificial heart is scheduled to be implanted into patients in four medical centers around the world. The device completely replaces the patient’s original heart.
The artificial heart consists of two cavities, mimicking the organ’s ventricles, which are separated by a moving membrane that’s hydraulically powered via a special actioning fluid. This membrane reproduces the action of the ventricular wall during contractions, creating blood flow in and out of the device. The system is works in conjunctions with sensors and a microcontroller that continuously adjust the activity of the prosthesis to match the needs of the patient.
>impalement injury with arterial involvement
>unknown mechanism where a length of u-channel post completely penetrated the right lateral to medial thigh and left medial to lateral calf
>obvious femur fracture with significant bleeding —tourniquet placed proximal to the impalement and stabilized as best as possible
>surgeons removed the post and inserted a shunt from the femoral to popliteal arteries to restore distal perfusion
>this is why we don’t attempt removal in the pre-hospital setting
>we cannot manage arterial involvement without significant blood loss and inadequate distal perfusion, risking loss of life and limb
Good X ray.
Think however that a humeral brace would serve this mid shaft fracture better than the POP it seems to be in at the moment.
These are not done routinely in A+E in the UK. Get to know the plaster technicians at the fracture clinic in your hospital and be nice to them. They might just get it sorted for you. I find chocolate bribery always works ; )

Different sites of myocardial infarct
1 = subendocardial infarction,
2 = intramural infarction,
3 = transmural infarction,
4 = subepicardial infarction.
(MV = mitral valve, TV = tricuspid valve, LV = left ventricle, RV = right ventricle, S = septum, P = papillary muscle.)

Stunning. Such a small thing, but perfect.
