A 26-year-old primigravida with a spontaneously conceived monochorionic diamniotic twin pregnancy was diagnosed with an acardiac twin at 12 weeks (Fig. 1). She underwent interstitial laser under local anesthesia at 13 weeks (Fig. 2). The pump twin remained healthy on subsequent scans (Fig. 3). She went in spontaneous labor at 39 weeks and delivered a healthy baby boy weighing 3100 g with Apgar 9/10.
