In a blinded, prospective, angiographically correlated study design, 12-lead continuous ST-segment recovery analysis shows promise as a practical noninvasive marker of failed reperfusion that may contribute substantially to currently available bedside assessment. Our data also suggest that patients with TIMI 2 flow or with collateralized occlusions may represent a physiological spectrum definable with ST-segment recovery analysis.

We report the a case of hugging balloons through an 8-French guiding catheter to stabilize an ectatic right coronary artery following failed thrombolytic therapy in the setting of acute myocardial infarction. Angiographic follow-up at 1 wk and 6 mo revealed persistent vessel patency.
