Abrupt left coronary artery malperfusion secondary to acute type A aortic dissection after weaning from cardiopulmonary bypass: a case report.

ABSTRACT:

Introduction

Acute Stanford type A aortic dissection (ATAAD) is a lethal emergency. However, even with instant surgical repair, early mortality is up to 20%. ATAAD complicated by coronary artery involvement is considered rare but life-threatening because this can cause coronary artery malperfusion which results in acute myocardial infarction. In particular, left coronary artery malperfusion can bring worse outcomes than right coronary artery malperfusion, but there are few reports of left coronary artery involvement secondary to ATAAD.

Case presentation

We present a case of a woman who got emergency open heart surgery due to ATAAD. After the hemiarch replacement, the first weaning from bypass was relatively smooth. However, as soon as starting infusion protamine, we found ou
