Article Synopsis
- The study aimed to understand how pregnancy affects the right side of the heart and any related changes postpartum, particularly focusing on women with cardiovascular risk factors.
- It involved 51 healthy pregnant women and 79 with cardiovascular risk, using echocardiography to collect data at various stages of pregnancy and postpartum.
- Results showed similar enlargement of the right atrium and ventricle during pregnancy, with normalization by six months postpartum; however, the group with cardiovascular risk factors exhibited lower heart strain measurements and ongoing issues with diastolic function recovery.
Introduction And Objectives: Echocardiography guidelines suggest normalizing left ventricular (LV) volumes and mass (LVM) to body size. During pregnancy, continuous weight variation impacts on body surface area (BSA) calculation, limiting the longitudinal analysis of cardiac remodeling (CR) and reverse remodeling (RR) variables. Our aim was to identify the most common indexing methodologies in the literature on pregnant populations through a systematic review; and, to compare four scaling methods: (i) none (absolute values); (ii) indexing to the BSA before pregnancy; (iii) allomeric indexing; and (iv) indexing to BSA measured at the same day of cardiac assessment, using an illustrative example.

Thus, recent guidelines suggest extending the follow-up period to 1 yr after delivery. We aimed to evaluate cardiovascular remodeling during pregnancy and determine which CVR factors and potential biomarkers predict postpartum cardiac and vascular reverse remodeling (RR).

Bariatric patients who experience massive weight loss frequently seek body contouring procedures and represent a high-risk group. This study aimed to evaluate the effects of abdominoplasty with Scarpa Fascia preservation versus the classical technique in a bariatric population.

Methods: A retrospective case-control study was performed with patients from a tertiary hospital who underwent primary ACL surgery and had preoperative magnetic resonance imaging (MRI). These subjects were matched by age and sex in a 1:1 ratio to patients who had an MRI without ACL tear.
Background: Little is known about the impact of severe aortic stenosis (AS) in aortic stiffness and if there is any change after removing AS barrier with aortic valve replacement (AVR) surgery.
Objective: To estimate carotid-femoral pulse wave velocity (PWV) changes after AVR surgery and to define PWV predictors in severe AS patients.
Methods: Single-center retrospective cohort, including patients with severe AS who underwent AVR surgery with bioprostheses, between February 2017 and January 2019 and performed PWV measurements (Complior®) before and after the procedure (2±1 months).
Objective: This study aimed at determining the relationship between fetal chromosomal disorders (CDs), including trisomy 21 (T21), and on first- and second-trimester maternal blood plasma, to identify the time-course metabolic adaptations to the conditions and the possible new plasma biomarkers. Furthermore, a definition of a joint circulatory (plasma) and excretory (urine) metabolic description of second-trimester CDs was sought.
Study Design: Plasma was obtained for 119 pregnant women: 74 controls and 45 CD cases, including 22 T21 cases.
