Porcine. At 67 I=B4m old enough that they figure that there is an adequate chance that I=B4ll drop dead before this one wears out.
The new valve is in place and working fine, but the rest of the heart is taking its time to adapting to not having to pump through a
100mm Hg pressure drop across the old aortic valve. My pulse rate climbed about 180bpm over the first few days, which has been controlled with some 300millligram per day of beta-blocker. but the pulse rate is irregular, and I=B4m not up to much.The operating hospital tried electro-cardio-version on Saturday, when the irregularity first set in, and that worked fine for a couple of hours. The hospital where I=B4ve been looked after since Sunday won=B4t try again until my anti-coagulant drugs are consistently giving clotting time three time the number they first measured, which usually takes about a weeek to set up, so I=B4m stuck in hospital for a few days yet.
