Abstract Background: Pulmonary Hypertension is a life-threatening disease characterized by a progressive increase of pulmonary vascular resistance that often leads to right ventricular (RV) failure and death. Major discoveries have been obtained within the last decade in the field of hereditary predisposition to pulmonary arterial hypertension (PAH). At least 6% of all PAH cases are familial in origin known as Familial Pulmonary Arterial Hypertension (FPAH) and display autosomal dominant inheritance with incomplete penetrance. While early diagnosis is associated with improved long-term survival, however at present, most patients are diagnosed at a very advanced stage of HPAH indicating that the early screening for HPAH is crucial. In this regard, genetic testing is an effective strategy for the early diagnosis and management of PAH, specifically Hereditary Pulmonary Arterial Hypertension (HPAH). We present two cases of Familial Pulmonary Arterial Hypertension and in-depth analysis of diagnostic cascade to allow an earlier and more reliable diagnosis of possible Hereditary Pulmonary Arterial Hypertension (HPAH).
Case Illustration: Familial cases, a 44-years old man and his son a 17-years old boy, came with chief complaint of dyspnea. His daughter or his sister passed away when 4 years old due to PH. Both patients had been subsequently diagnosed with PAH with possible HPAH after the exclusion of primary and secondary heart anomalies using electrocardiography, echocardiography, and cardiac marker test. Both patients subsequently were performed right heart catheterization (RHC).
Conclusions: We describe familial cases of pulmonary hypertension with clinically presenting right-sided heart failure. Diagnostic investigation was performed according to recent guideline to rule out and rule in all the possible cause of pulmonary hypertension. However, the final assessment showed unknown cause of pre-capillary pulmonary hypertension. Therefore, genetic investigation should be performed in precision medicine era due to high possibility of hereditary pulmonary arterial hypertension.
