Pharmacogenomics (PGx) has emerged as a powerful tool to personalize drug selection and dosing based on a patient’s genetic profile. However, there are a range of challenges that impede uptake in current clinical practice. For example, clinicians often express frustration with commercially available PGx panel tests, which fail to consistently include all key actionable PGx genes (according to the Clinical Pharmacogenetics Implementation Consortium (CPIC), Food and Drug Administration (FDA) PGx guidelines, or The Dutch Pharmacogenetics Working Group (DPWG) guidelines) and instead are too long with clinically unimportant information (unvalidated genotypes). Additionally, the lack of EMR integration, clinician education and awareness of the benefits of PGx impedes uptake. This paper examines key challenges identified in clinical practice and proposes future directions, focusing on limiting PGx reports to essential data, providing point-of-prescription alerts, and establishing reimbursement pathways that encourage adoption. Future directions include leveraging large language models, integrating point-of-prescription alerts and phenoconversion calculators into the electronic medical record, increasing the genomic diversity of PGx study populations, and streamlining coverage by payers.

The use of an alteplase (Activase) purge solution to address Impella ventricular assist device “thrombosis” or “purge system occlusion” has been mainly documented with earlier generation Impella devices (CP, 2.5, 5.0). Here, we report the use of an alteplase purge solution to manage Impella 5.5 purge system occlusion in a 31-year-old male admitted to the cardiac care unit in cardiogenic shock and listed for a heart transplant. Throughout the purge system occlusion, the patient demonstrated hemodynamic stability and overall pump flow and cardiac output were preserved. Initially, there was a lack of response in purge flow and pressure observed at the lower concentration of alteplase purge solution (0.04 mg/ml), yet after using the alteplase 4 mg/50 ml purge (0.08 mg/ml) solution concentration, a response was seen. No bleeding or hemodynamic complications were observed. In addition, a suggested management workflow and review of the case reports and case series published to date regarding Impella purge system occlusion is included in this article.
