A critical understanding of cardiac anatomy is essential for design engineers and clinicians with the intent of developing and/or employing improved or novel technologies or therapies for treating an impaired atrioventricular valve. Likewise, such knowledge is required for directing translational research, including initiating preclinical research, assessing the feasibility of clinical trials, and performing first-in-man procedures. There are two atrioventricular valves in the human heart, namely the tricuspid and mitral valves. Both are complex structures whose normal anatomies can vary greatly amongst individuals, and also become modified by disease processes. In this review, we discuss the anatomy, pathology, and issues related to surgical and transcatheter repair of the atrioventricular valves in a translational manner. This article is part of a JCTR special issue on Cardiac Anatomy.

Mid-term outcomes of atrioventricular valve repair in functional single ventricle patients.
Front Cardiovasc Med

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.
Fetal Characteristics and Perinatal Outcomes in Tetralogy of Fallot Without a Ductus Arteriosus.

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).

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.

Autophagy-lysosomal degradation is a conserved homeostatic process considered to be crucial for cardiac morphogenesis. However, both its cell specificity and functional role during heart development remain unclear. Here, we introduced zebrafish models to visualize autophagic vesicles and track their temporal and cellular localization in the larval heart.

Background: In patients with adult congenital heart disease (ACHD), significant atrioventricular valve regurgitation is an important risk factor for poor outcomes, such as heart failure. However, in many cases, transcatheter intervention may reduce the risk profile to avoid a high surgical risk.
Case Summary: A 44-year-old man with complex ACHD in the form of a double-inlet left ventricle, congenitally corrected transposition of the great arteries, pulmonary atresia, atrial septal defect, and patent ductus arteriosus was referred for the treatment of severe tricuspid regurgitation.
