Hereditary thrombophilia and genetic mutation in plasminogen activator inhibitor-1 and MTHFR A1298C genesin conjunction with cleft palate resulted in poor lactation and hypernatremic dehydration. A peripherally insertedcentral catheter in the inferior vena cava was an additional underlying factor. Thrombosis mass was dislodged to theright atrium while asymptomatic and accidentally detected during routine echocardiography.Conclusion: Surgical thrombectomy was done successfully, and the mass was removed from the right atrium. %U https://ijn.mums.ac.ir/article_14727_e11a9cb6c33e4cf932092328ce675f55.pdf
