Many doctors believe that closing the left atrial appendage (with a device) will help reduce stroke and bleeding. The idea behind stroke reduction is that occluding the appendage takes away a common area where clots form. I’ve already told you that peri-device leaks are associated with an increase in stroke risk.

Thromboembolism can lead to stroke (and this is a more common cause of stroke in the setting of sCAD than hypoperfusion). Epidemiology Common cause of strokes in young people; sCAD accounts for 15-24% of strokes in patients < 45 years. Rare cause of stroke overall – incidence is 1.72

She had a history of neonatal stroke for which she had received physical and occupational therapy. The mother and medical records confirmed that a cause had not been determined but the child had a neonatal arterial ischemic stroke. The mother had been evaluated for hypercoagulability which was negative.

The idea is to prevent stroke and reduce bleeding by plugging the appendage. But, get this: PREVAIL did not find noninferiority in its first co-primary endpoint of stroke, systemic embolism or cardiovascular death. One makes an ultrasound device, the other a radiofrequency device. This was a recent FDA approval.

Stroke occurred in 7 patients (0.12%). Notable also that in the main paper, there was one TIA in the PFA arm and one stroke in the thermal arm but neither of these were in the MRI subgroup of the study. We really can’t say much about safety when only 600 patients are randomized. We would call these silent brain lesions.

But the duration of symptoms was prolonged and so to avoid the risk of stroke, AV nodal blockade (rate control) was preferred. We want to avoid a stroke.

My opinion was that it was not a cath lab case, but I did suggest they do a bedside ultrasound to look for an anterior wall motion abnormality. Notice also the very small LV cavity size at both diastole and systole (poor LV filling with good contractility) and apparent low stroke volume. I did not have more information at the time.

There is very little filling, and thus very poor stroke volume. Further ultrasound showed no B-lines (no pulmonary edema). This is because of the large LV myocardial mass due to HOCM. The heart rate is too fast for this poor filling. Preload must be increased and the heart rate slowed in order to allow more LV filling.
