The challenge of cardiomyopathies and heart failure in pregnancy.

ABSTRACT

PURPOSE OF REVIEW To discuss the risk preexisting or new onset cardiomyopathy/heart failure (CMP/heart failure) in pregnant woman, and recent insights regarding their management and therapy. RECENT FINDINGS: Recent data from the European Registry on Pregnancy and Heart disease of the European Society of Cardiology (ROPAC) suggest that, after an adequate prepregnancy evaluation in specialized centres, the vast majority of pregnancies are safe for both mother and foetus. A tailored approach is required according to cardiac phenotype (i.e. type of cardiomyopathy), clinical and functional status, and new potential treatments (i.e. bromocriptine in patients with peripartum cardiomyopathy). SUMMARY: In clinical practice, prepregnancy cardiac evaluation is mandatory, including evaluation of the clinical status, standard ECG (and 24-48 h monitoring, whenever required), and imaging, to define the individual risk profile. In presence of severe symptoms (advanced New York Heart Association class), cardiac dysfunction (moderate-severe reduced ejection fraction), haemodynamic load (left ventricular outflow tract obstruction, pulmonary hypertension), pregnancy is contraindicated. A tailored monitoring is warranted in other cases (mild-moderate risk pregnancies). Likewise, in women who develop PPCM, a risk stratification and tailored monitoring and therapy should be achieved by an expert, multidisciplinary team, including cardiologists, gynaecologists, obstetricians, genetic counsellor, and psychologists.
