Outcome of Pregnancy and Effects on the Right Heart in Women With Repaired Tetralogy of Fallot

Pregnancy-Related Obstetric and Cardiologic Problems in Women After Atrial Switch Operation for Transposition of the Great Arteries

“…Further research in this field including prospective studies with brain natriuretic peptide data would be useful in identifying patients who are going into cardiac failure. 33 This study was performed at 3 tertiary care centers for adults with CHD. The prevalence of more complex anomalies in these institutions is likely to be higher than either in community-based hospitals or even in departments for cardiology.…”

Cardiovascular Events in Pregnancy With Hypertrophic Cardiomyopathy

“…The circulating blood volume increases more rapidly after 20 gestational weeks and reaches a plateau at 32 gestational weeks of 40-45% of the nonpregnant volume. 10, 11 In HCM, the preload increase, afterload decrease and increase in cardiac contraction are precipitating factors because the ventricular blood volume decreases and left ventricular outflow obstruction deteriorates. The influence of these pregnancy-related physiologic changes on the circulation in HCM is not well understood.…”

“…The events related to arrhythmia mainly occurred in the early stage of pregnancy or at approximately 30 gestational weeks. A total of 4 pregnancies were terminated because of a cardiovascular event (cases 8,10,11,12). In case 8, the pregnancy was terminated at 31 gestational weeks because the mother was developing pulmonary hypertension and the PG of LVOTO had increased rapidly (peak PG 57 mmHg).…”

Analysis of Anticoagulant Therapy by Unfractionated Heparin During Pregnancy After Mechanical Valve Replacement

“…At 12 h after delivery, unfractionated heparin was adechanical valve replacement during pregnancy jeopardizes both mother and fetus, 1 so the procedure should involve appropriate anticoagulant therapy to obviate the high risk for thrombosis, which is accentuated during pregnancy because of the intravascular volume. 2, 3 However, prospective study of anticoagulant therapy applied during mechanical valve replacement has not been performed and consensus has not been obtained regarding the use of anticoagulant therapy in mechanical valve replacement.…”
