At my little hospital we usually EKOS or half dose TPA for sub massive PE but we use the MOPETT trial protocol of TPA 10mg push followed by 40mg over 2 hrs. Is there a trial that uses the 50mg over an hour that is suggested here? Thanks

At our small/rural hospital, we have chosen the following lytic options for massive PE:

  1. Cardiac arrest: alteplase 50 mg over 2min
  2. Unstable: alteplase 20 over 2 min, followed by 80 mg over 2 hours
  3. Stable: 100 mg over 2hours.

I think TNK would be easiest in arrest scenario, such as I has few months ago, but pharmacy was most comfortable with alteplase.

Scott, in your experience have patients who fell into the massive super sick category responded similarly to the 50mg over 1hr vs peri-code 50mg over 5 mins? When the ICU docs at my hospital encounter these patients they favor giving lytics as fast as possible to attenuate the hemodynamic instability. Also any thoughts on using your 25mg over 6 hrs in the same massive sick category regardless on bleeding risk?

Hi! Great summary of the complicated PE universe.

Could you please comment on the hemodynamic stable, severely hypoxic patient?
What is your treatment approach? How much lysis do you give?

I’ve encountered case reports about using a Swan-Ganz catheter as a way of catheter directed thrombolysis in high bleeding risk patients when commercial dedicated kits or personnel were unavailable. I personally think it is a great option to give low dose alteplase directly into pulmonary artery until we obtain evidence that periprheal low-dose infusions are noniferior. What do you think about it?
Also might be the best use for Swan-Ganz catheters in the bedside echo era.
