No maternal deaths or serious CV complications Uncorrected severe coarctation however continues to be a contraindication to pregnancy due to the unpredictable risk of dissection, rupture, severe hypertension during pregnancy and adverse fetal outcome. Pulmonary valve stenosis Patients with pulmonary valve stenosis during pregnancy usually do well. The exception is the patient with critical pulmonary stenosis, i.e., when right ventricular pressure exceeds left ventricular pressure. In such patients, pulmonary balloon valvuloplasty is the procedure of choice. Overall patients with regurgitant lesions tolerate pregnancy well if asymptomatic and if ventricular function is normal.
