Article Synopsis
  • The study aimed to analyze the effects of maternal and fetal heart disease on pregnancy outcomes, focusing on both fetal/neonatal and obstetric events.
  • It involved 1,011 singleton pregnancies, comparing those with only maternal heart disease to those with both maternal and fetal heart disease.
  • Results showed that pregnancies with both conditions had significantly higher instances of fetal/neonatal adverse events and spontaneous preterm birth, highlighting the need for more extensive research on their links to preeclampsia.

Gated radionuclide angiography and myocardial perfusion imaging were developed in the United States and Europe in the 1970's and soon adopted in Canadian centers. Much of the early development of nuclear cardiology in Canada was in Toronto, Ontario and was quickly followed by new programs across the country. Clinical research in Canada contributed to the further development of nuclear cardiology and cardiac PET.

Background: Although pregnancy outcomes in women with normally functioning bioprosthetic valves (BPVs) are often good, structural valve dysfunction (SVD) may adversely affect pregnancy outcomes, but this has not been studied.

Objectives: The aim of this study was to examine outcomes in pregnant women with BPVs and the association with SVD.

Methods: Pregnancy outcomes in women with BPVs were prospectively collected.

Background: Clinical utility of cardiac biomarker testing during pregnancy in women with preexisting cardiac disease is not well known. We studied the levels and temporal trends of NT-proBNP (N-terminal pro-B-type natriuretic peptide) and hs-cTnI (high-sensitivity cardiac troponin I) throughout pregnancy in women with preexisting cardiac disease and sought to assess the association between NT-proBNP and hs-cTnI and pregnancy outcomes.

Methods: Three hundred seven pregnant women with preexisting cardiac disease were prospectively recruited.

Article Synopsis
  • The study aimed to explore the impact of the COVID-19 pandemic on adults with congenital heart disease, focusing on psychological distress, day-to-day functioning, and their experiences with COVID-19 symptoms and testing.
  • Results showed an increase in psychological distress during the early pandemic, with stress levels returning to baseline by late 2020, while other distress categories like anxiety and depression remained high, particularly among women.
  • Out of 579 survey respondents, 25% reported COVID-19 symptoms, 31% sought testing, but only 2% tested positive, and 9% lost their jobs due to pandemic-related issues.
