Treatment of Severe Symptomatic Aortic Stenosis During Pregnancy: A Potential Role for TAVR?

A 35-year-old woman presented at 22 weeks gestation with severe symptomatic aortic stenosis with a mean gradient of 94 mm Hg and an aortic valve area of 0.53 cm. After multidisciplinary discussion, she underwent transcatheter aortic valve replacement during pregnancy.

Cardiovascular Fellowship Training in Cardio-Obstetrics: JACC Review Topic of the Week.

The United States has the highest maternal mortality in the developed world with cardiovascular disease as the leading cause of pregnancy-related deaths. In response to this, the emerging subspecialty of cardio-obstetrics has been growing over the past decade. Cardiologists with training and expertise in caring for patients with cardiovascular disease in pregnancy are essential to provide effective, comprehensive, multidisciplinary, and high-quality care for this vulnerable population.

Arterial Stiffness and Vascular Load in HFpEF: Differences Among Women and Men.

Background: Mechanisms underlying sex differences in heart failure with preserved ejection fraction (HFpEF) are poorly understood. We sought to examine sex differences in measures of arterial stiffness and the association of arterial stiffness measures with left ventricular hemodynamic responses to exercise in men and women.

Methods: We studied 83 men (mean age 62 years) and 107 women (mean age 59 years) with HFpEF who underwent cardiopulmonary exercise testing with invasive hemodynamic monitoring and arterial stiffness measurement (augmentation pressure [AP], augmentation index [AIx], and aortic pulse pressure [AoPP]).

Exercise Intolerance in Heart Failure With Preserved Ejection Fraction: Arterial Stiffness and Aabnormal Left Ventricular Hemodynamic Responses During Exercise.

Background: Arterial stiffness is thought to contribute to the pathophysiology of heart failure with preserved ejection fraction (HFpEF). We sought to examine arterial stiffness in HFpEF and hypertension and investigate associations of arterial and left ventricular hemodynamic responses to exercise.

Methods And Results: A total of 385 symptomatic individuals with an EF of ≥50% underwent upright cardiopulmonary exercise testing with invasive hemodynamic assessment of arterial stiffness and load (aortic augmentation pressure, augmentation index, systemic vascular resistance index, total arterial compliance index, effective arterial elastance index, and pulse pressure amplification) at rest and during incremental exercise.
