Despite the challenges associated with periprocedural imaging, transcatheter tricuspid valve interventions have shown important impact on outcomes. A comprehensive understanding of the anatomy of the right heart and surrounding structures is crucial. One way to optimize these interventions is by identifying the optimal fluoroscopic viewing angles along the S-curve of the tricuspid valve.

Department of Pediatric Cardiovascular Surgery, JCHO Kyushu Hospital, Kitakyushu, Japan.

Article Synopsis
  • Ventricular septal defect (VSD) is the most common type of congenital heart disease and often requires surgical intervention.
  • The VSD patch closure surgery is crucial not only for simple VSDs but also for more complex congenital heart defects like tetralogy of Fallot and complete atrioventricular septal defect.
  • To ensure successful closure without complications, surgeons must have a thorough understanding of VSD anatomy and skillfully perform sutures and ligatures.

Aims: Right ventricular reverse remodelling (RVRR) is linked to improved survival in patients with severe tricuspid regurgitation (TR) and right-sided heart failure who underwent interventional treatment. However, the role of residual TR on RVRR remains unclear. In this analysis the impact of residual TR on RVRR after interventional TR treatment, which was validated by two independent cohorts at four sites using echocardiography or cardiac magnetic resonance (CMR) imaging, was investigated.

Ultrasound in Cardiac Electrophysiology and Biomechanics Key Laboratory of Sichuan Province, Sichuan Clinical Research Center for Cardiovascular Disease, Sichuan Provincial People's Hospital, University of Electronic Science and Technology of China, Chengdu, 610072, China.

Transthoracic echocardiography (TTE) is widely recognized as one of the principal modalities for diagnosing tricuspid regurgitation (TR). The diagnostic procedures associated with conventional methods are intricate and labor-intensive, with human errors leading to measurement variability, with outcomes critically dependent on the operators' diagnostic expertise. In this study, we present an innovative assessment methodology for evaluating TR severity utilizing an end-to-end deep learning system.

  • The study aimed to evaluate how well right ventricular free wall longitudinal strain can predict peri-operative mortality in patients with severe tricuspid regurgitation undergoing tricuspid valve surgery, compared to traditional risk scores.
  • Researchers analyzed data from 110 patients, ultimately focusing on 79 who met criteria, finding that 9% died within 30 days post-surgery.
  • Results showed that right ventricular free wall longitudinal strain was the strongest predictor of mortality, outperforming classic risk scores when combined, indicating its potential importance in patient assessment before surgery.*

Purpose: Finite element simulations are an enticing tool to evaluate heart valve function; however, patient-specific simulations derived from 3D echocardiography are hampered by several technical challenges. The objective of this work is to develop an open-source method to enforce matching between finite element simulations and in vivo image-derived heart valve geometry in the absence of patient-specific material properties, leaflet thickness, and chordae tendineae structures.

Methods: We evaluate FEBio Finite Element Simulations with Shape Enforcement (FINESSE) using three synthetic test cases considering a range of model complexity.

Article Synopsis
  • - This study investigated how mitral valve prolapse (MVP) affects heart structure, particularly focusing on the right side of the heart, in patients without significant regurgitation.
  • - Out of 49 MVP patients and 54 healthy controls, findings revealed that patients with MVP had enlarged tricuspid annuli and right atrial volumes compared to controls, even if they experienced tricuspid valve prolapse (TVP).
  • - The study concluded that changes in right heart structures in MVP patients should be carefully monitored, as increased tricuspid annular size was linked to higher TAPSE values, indicating a potential need for alternative measurements in assessing heart function.

Article Synopsis
  • This study investigates the long-term durability of bioprosthetic valves in patients with bicuspid aortic valve (BAV) after undergoing transcatheter aortic valve replacement (TAVR), compared to patients with tricuspid aortic valve (TAV).
  • A total of 170 BAV and 145 TAV patients were followed for an average of over 5 years, showing no significant differences in rates of structural valve deterioration or bioprosthetic valve failure between the two groups.
  • The findings suggest that TAVR provides satisfactory long-term valve performance for patients with BAV, comparable to those with TAV, indicating good outcomes for both groups.
