Preimplantation Genetic Testing for Inherited Heart Diseases

Purpose of ReviewPreimplantation genetic testing for monogenic conditions (PGT-M) is an increasingly utilized reproductive technology for patients with inherited heart disease (IHD). In this article, we provide an overview of the PGT-M process, including current guidance about its use, and review recent data about the perspectives and experiences of patients considering the use of PGT-M.Recent FindingsPGT-M is used for a variety of IHDs; however, there is evidence that providers do not consistently raise this topic with patients, which may be due to a lack of knowledge about PGT-M. Regardless of the condition, patients report similar motivations for using PGT-M, such as the desire for a healthy child and the wish to save offspring from suffering. Patients make individualized decisions that are influenced by their lived experience with the diagnosis, a sense of responsibility to prevent disease transmission and other personal and logistical considerations. The PGT-M process can be challenging and each patient requires comprehensive information and support throughout.SummaryPGT-M is a complex multi-step process whereby individual decision-making is influenced by various intrinsic and extrinsic factors. Adequate information and support are necessary for individual decision-making and expectation-setting. This is best accomplished by a multidisciplinary collaboration including cardiology, genetics, reproductive endocrinologists, and obstetric providers.
