Spectrum of cardiovascular findings during pregnancy and parturition at a tertiary referral center.

Aim: To analyze the spectrum of cardiovascular diseases occurring during pregnancy and delivery at a tertiary referral center. Methods: All patients presenting at our institution with pre-existing or first diagnosis of cardiac disease were recruited. Cardiac and obstetric complications and maternal and neonatal outcomes were recorded. Results: Fifty-two pregnancies in 49 women, including three pregnancy terminations were analyzed. Cardiac lesions were congenital in 26 (53.1%) and acquired in nine (18.4%); six patients (12.2%) had cardiomyopathies, eight (16.3%) arrhythmic conditions. A total of 42 women (85.7%) had a pre-existing cardiac condition and seven (14.3%) presented with first manifestation. Overall 22 cardiac complications occurred: five in pregnancy, eight around parturition, nine during follow-up. They included > 1 New York Heart Association functional class deterioration (n = 5), congestive heart failure/cardiomyopathy (n=5), valve replacement (n=4), sustained arrhythmia (n=3), cerebral insult, aortic dissection, transplantation (one case each), and death (n = 2). Mean gestational age at delivery was 36+6. The cesarean section rate was 77.5%; 31.6% were performed for cardiac indications. Obstetric complications happened in 23 pregnancies (46.9%). There was no perinatal loss; cardiac defects were diagnosed in 9.3% (n = 5) of offspring. Conclusion: Cardiovascular diseases occurring during pregnancy and parturition comprise a heterogeneous spectrum of conditions. Established scores aid in the identification of high-risk patients; however, in our series 14.3% women had been healthy previously.
