Guide Catheter Recall; Stroke Thrombus Migration; EXCEL Defector Speaks Out

Interventional cardiology news to note

Medtronic's 6-F Sherpa NX Active guide catheters are under Class I recall due to a risk of the outer material separating and leaving fragments in the patient's bloodstream.

Acutus Medical joined with Innovative Health, a company that reprocesses single-use catheters, to sell hospitals their electrophysiology products at a reduced price. This can bring the cost of each atrial fibrillation ablation down by 30%, according to a press release.

Among those with chest pain and non-obstructive coronary artery disease, there are sex differences in coronary physiology: women tend to have lower coronary flow velocity reserve, higher coronary blood flow at rest, and lower coronary blood flow at hyperemia. (EuroIntervention)

Researchers came up with a troponin T threshold to identify patients at a higher risk of mortality due to myocardial injury stemming from PCI for chronic total occlusion. (JACC: Cardiovascular Interventions)

Thrombus migration occurred in more than one-fifth of acute ischemic stroke patients in the MR CLEAN registry, researchers reported in Stroke. Thrombus migration was associated with a lower chance of complete reperfusion and successful reperfusion -- but better functional outcome in the subgroup of patients with an initial M1 clot on noninvasive imaging.

Incidence and severity of bleeding after peripheral revascularization doesn't differ from that seen following coronary revascularization or lower extremity amputation, according to a post hoc analysis of the EUCLID trial. (Circulation: Cardiovascular Interventions)

One of the EXCEL trial's leaders said he withdrew his name from the paper reporting 5-year results because he believed it exaggerated the performance of percutaneous coronary intervention versus coronary artery bypass grafting, TCTMD reported.
