Purpose To investigate the determinants and effect of right ventricular (RV) dysfunction in aortic regurgitation (AR) using cardiac MRI. Materials and Methods This study included patients with moderate or severe AR who were enrolled in the DEBAKEY-CMR registry between January 2009 and June 2020. Patients with previous valve intervention, cardiomyopathy deemed unrelated to AR, severe aortic stenosis, and other confounders were excluded.

A self-expanding valve was deployed successfully, but intraoperative transesophageal echocardiography (TEE) confirmed an acute type A aortic dissection (ATAAD), necessitating immediate intervention. Multiple intraoperative imaging modalities were utilized for deployment of a conformable GORE TAG (cTAG) stent graft for thoracic endovascular aortic repair (TEVAR).

Objectives: This study sought to evaluate differences in clinical outcomes according to sex after FFR-guided PCI with current generation DES compared with CABG.
Methods: The FAME 3 trial was an investigator-initiated, randomized controlled trial, comparing FFR-guided PCI with current generation DES or CABG in patients with 3-vessel coronary artery disease.
Article Synopsis
- The study examined differences in echocardiographic assessments of native and bioprosthetic aortic valves between core laboratories and clinical centers, finding clinically relevant discrepancies.
- Data was collected from the PERIGON trial, which involved patients undergoing surgical aortic valve replacement, and involved comparing echocardiographic results from centers to independent analysis by a core lab.
- Results showed that while some continuous measurements had high agreement (around 0.90), there were notable variances, particularly in left ventricular outflow tract area and stroke volume, indicating the need for standardized evaluation practices.
Article Synopsis
- * The J-Valve device, developed by JC Medical, shows promising outcomes, particularly in patients with complex anatomical challenges.
- * Two successful cases of transcatheter aortic valve replacement using the J-Valve were reported in patients who had significant aortic angulation.
