CardioNerds (Amit Goyal and Daniel Ambinder) join Dr. Kushani Gajjar and Dr. Mitha Naik from the Allegheny Health Network for a walk along the Three Rivers Trail in Pittsburgh. They discuss a case of young woman in her third trimester of pregnancy with a known history of pulmonary arterial hypertension. The management of pulmonary hypertension in pregnancy and RV failure in the context of pregnancy is described. The E-CPR segment is provided by Dr. Nandita Scott, Co-Director Corrigan Women's Heart Health Program and Cardiovascular Disease and Pregnancy Service at Massachusetts General Hospital. Special cameo appearance by Dr. Dani Crousillat.

Patient Summary - Pulmonary Hypertension in Pregnancy A 33-year-old woman in the third trimester of pregnancy, with a known history of untreated PAH in the setting of TKI therapy, presents with shortness of breath. She is found to have PA pressure greater than systemic pressure with PASP >130. We describe the management of PH and RV failure in the context of a pregnancy. The patient was admitted to the ICU where a multidisciplinary team was mobilized, involving high risk ob-gyn, maternal fetal medicine, critical care, anesthesiology, and advanced heart failure. They began pulmonary vasodilators including treprostinil, tadalafil and inhaled nitric oxide. They also added inotropic and vasopressor support for right ventricular dysfunction with her severe PAH. Fetal heart monitoring was performed. PAH also led to worsening of known chronic thrombocytopenia in the setting of CML. HELLP syndrome was ruled out. The patient had preterm rupture of membranes at 32 weeks of gestation and the team pursued assisted vaginal delivery to prevent vagal response. Following successful delivery, the patient elected to undergo intra-uterine device placement. Post-delivery, vasopressors and inotropes were weaned, and she was discharged on treprostinil, ambrisentan and tadalafil. Thankfully both the mother and baby returned healthy and well at 1 month follow up. Case Media - Pulmonary Hypertension in Pregnancy CMRCXRTTETTEClick to Enlarge Episode Teaching - Pulmonary Hypertension in Pregnancy Pearls - Pulmonary Hypertension in Pregnancy Pulmonary Hypertension is defined as a mean pulmonary arterial pressure (mPAP) of >20mmHg. There are 5 major types of pulmonary hypertension. Risk modifiers include symptom burden, exercise capacity, presence of pericardial effusion, RV function and hemodynamics.Multidisciplinary care teams are the key to achieving optimal pregnancy outcomes in patients with PH. It is critical to create a team of experts with experience in pulmonary hypertension and plan for constant communication before, during, and after pregnancy.Pregnant women who are already on PAH therapy outpatient should continue them during pregnancy (under the direction of PH experts) except for endothelin receptor blockers which fall in pregnancy category X.PH during pregnancy is associated with up to 38% maternal mortality rate as the right ventricle (RV) is often unable to handle the volume shifts and hemodynamic changes that occur during pregnancy, labor, and delivery.Patients with RV failure leading to low cardiac output and hypotension, like in this case,
