Article Synopsis
  • The study aimed to assess the effectiveness of 2D-STI and RT-3DE imaging techniques in evaluating structural and functional changes in the left atrium of patients with paroxysmal atrial fibrillation after undergoing radiofrequency catheter ablation.
  • A total of 44 PAF patients and 32 healthy controls were examined, comparing echocardiographic parameters like left atrial dimensions, volumes, and ejection fractions before and at various intervals after the procedure.
  • Results showed that PAF patients had initially larger left atrial sizes and lower efficiency, but significant improvements in LA function and measurements were observed up to 6 months post-ablation, highlighting the usefulness of these imaging methods for treatment monitoring.

Background: Evidence remains limited on the association between maternal ozone (O) exposure and congenital heart defects (CHDs) in offspring, and few studies have investigated the interaction and modification of paternal smoking on this association.

Methods: Using a sample including pregnant women at high risk of fetal CHD (with metabolic disease, first-trimester viral infection, family history of CHD, etc.) from a maternal-fetal medicine study covering 1313 referral hospitals in China during 2013-2021, we examined the associations between maternal O exposure during 3-8 weeks of gestational age and fetal CHD in offspring and investigated the interaction and modification of paternal smoking on this association.

Article Synopsis
  • Isolated aortic brachiocephalic artery (IABA) is a rare congenital heart defect that's hard to diagnose before birth, with a very low prevalence in the prenatal population.
  • Through a study from 2012 to 2020, researchers found 10 cases of IABA, mostly showing an isolated left subclavian artery (ILSCA) and often associated with tetralogy of Fallot (TOF) and some instances of 22q11.2 deletion syndrome.
  • The "ice stick" sign identified in ultrasound images can be a crucial indicator for diagnosing IABA in fetuses.

Aortic stenosis has been shown to share the same risk factors as atherosclerosis which suggested a potential benefit from statins therapy. Fourteen studies which provided the effect of statins treatment on aortic stenosis (AS) were meta-analyzed, including 5 randomized controlled trials (RCTs) and 9 observational studies. In the RCTs, statins did not have any influence on peak aortic valve velocity, peak valve gradient, mean valve gradient, aortic valve area and aortic calcification compared to controls.
