Postconditioning with Lactate-enriched Blood for Cardioprotection in ST-segment Elevation Myocardial Infarction

The beneficial effects of reperfusion therapy for ST-segment elevation myocardial infarction (STEMI) is attenuated by reperfusion injury. No approach has ...

A 34-year-old man with severe heart failure was diagnosed with acute aortic regurgitation (AR) by transthoracic echocardiography (TTE). However, this differential diagnosis was incomplete. Only transesophageal echocardiography (TEE) revealed an intimal flap, leading to a diagnosis of Stanford type A aortic dissection. No abnormal findings were observed in the ascending aorta by contrast-enhanced computed tomography (CT). Aortic dissection confined to the sinus of Valsalva has rarely been reported; however, TEE should still be considered for the differential diagnosis of acute AR, even if there is no evidence of dissection by TTE or contrast-enhanced CT. 

Acute aortic regurgitation due to aortic dissection confined to the sinus of Valsalva.

Absence of reperfusion-induced arrhythmia in patients with ST-segment elevation myocardial infarction treated using postconditioning with lactate-enriched blood.

We recently reported a new approach for cardioprotection, postconditioning with lactate-enriched blood (PCLeB), and a patient with ST-segment elevation myocardial infarction (STEMI), in whom muscle squeezing of the culprit coronary artery was observed immediately after reperfusion with PCLeB. In this study, we examined the prevalence of muscle squeezing immediately after reperfusion in patients with anterior STEMI treated using PCLeB.
