With use of transvaginal ultrasonographic guidance, cardiac activity in an interstitial heterotopic pregnancy at 7 weeks' gestation was terminated. The interstitial pregnancy resolved, and a healthy term infant was delivered. If an early diagnosis of an interstitial heterotopic pregnancy is made, selective reduction may allow preservation of the intrauterine gestation without surgery.
