Mid-term outcomes of atrioventricular valve repair in functional single ventricle patients.
Front Cardiovasc Med
December 2024
Heart Center, The First Hospital of Tsinghua University, Beijing, China.
Background: Surgical treatment of functional single ventricle combined with atrioventricular valve regurgitation remains a clinical challenge. The outcomes of atrioventricular valve repair in patients with single ventricle are limited.
Methods: A retrospective study was conducted of all 28 patients with functional single ventricle treated with single-ventricle palliation who underwent atrioventricular valve operation at the First Hospital of Tsinghua University between April 2007 and October 2022.
Evaluation of left atrial function and the relationship between left atrial stiffness index and exercise capacity in hypertension-related heart failure with preserved ejection fraction.
Front Cardiovasc Med
December 2024
School of Medicine, University of Electronic Science and Technology of China, Chengdu, China.
Objective: The left atrial stiffness index (LASI) holds significance in the atrioventricular coupling function and heart failure progression. To assess left atrial function and evaluate the relationship between LASI and exercise capacity in hypertension-related heart failure with preserved ejection fraction (HT-HFpEF).
Methods: The study involved 62 healthy subjects and 163 patients with HT (112 patients in simple HT group and 51 patients in HT-HFpEF group).
Fetal Characteristics and Perinatal Outcomes in Tetralogy of Fallot Without a Ductus Arteriosus.
Pediatr Cardiol
December 2024
Division of Cardiology, Department of Pediatrics, Stanford University School of Medicine, Lucile Packard Children's Hospital, Palo Alto, CA, USA.
Absence of the ductus arteriosus (DA) is common in tetralogy of Fallot (TOF), occurring in up to 30% of cases. Yet, the clinical course and fetal echocardiographic features are not well described, limiting prenatal counseling. This study examines the fetal echocardiographic characteristics and perinatal outcomes in children with TOF absent DA (TOF/ADA), comparing them to those with a DA (TOF/DA).

J Cardiothorac Surg
December 2024
Department of Cardiology, Thomas Jefferson University, Philadelphia, PA, 19107, USA.
Background: Right ventricular (RV) function assessment by echocardiography can be challenging due to its complex morphology. Also, increasing use of sedation rather than general anesthesia for transfemoral approach transcatheter aortic valve replacement (TAVR) reduces the need for intraoperative transesophageal echocardiography (TEE). Recent clinical studies have demonstrated the importance of 3-dimensional (3D) echocardiography and a longitudinal strain for RV function assessment.
