Background: Mitral stenosis is the most important and common cardiac complication seen during pregnancy. Conception is discouraged in cases where pulmonary hypertension develops during the course of mitral stenosis. Successful general and regional anaesthetic interventions have been reported in some cases of severe pulmonary hypertension.
Case reports: We present our experiences with anaesthetic management in two pregnant patients with pulmonary hypertension due to mitral valve stenosis.
Conclusion: We preferred to continue spinal anaesthesia because gradually increasing the local anaesthetic dose during the procedure may minimise probable undesirable haemodynamic changes, such as hypotension and tachycardia.
