Spontaneous Coronary Artery Dissection Associated With Infertility Treatment

Assisted conception involving hormonals is a risk factor for spontaneous coronary artery dissection (SCAD), and pregnant women with spontaneous coronary artery dissection are more likely to have had treatment for subfertility. Increasingly, there is a risk of maternal death in women after assisted conception, and so, the need to assess the cardiovascular sequelae after assisted conception is imperative. This is an illustrative case of spontaneous coronary artery dissection shortly after a repeat cycle of in vitro fertilisation (IVF). The aetiology of spontaneous coronary artery dissection is believed to be multi-factorial, affecting mostly young women, a population similar to women requiring assisted conception. The oestrogen and progesterone used in in vitro fertilisation are believed to trigger structural weakening in the coronary blood vessels, leading to vascular rupture. Repeat in vitro fertilisation cycles and successful conception are thought to increase spontaneous coronary artery dissection risk by increasing hormonal exposure. The management of spontaneous coronary artery dissection is dependent on if pregnancy has been achieved or not, and a multi-disciplinary approach to its management is essential. More research is needed to identify women at higher risk of this life-threatening event.
