Real-time three-dimensional transesophageal echocardiography and three-dimensional printing: detection of multiple perivalvular leaks after mitral valve replacement—a case report and literature review

ZWZhirong WangQWQiuxian WanCFChengming Fan

Key Result

The synergistic integration of real-time 3D transesophageal echocardiography and 3D printing successfully guided the transcatheter closure of multiple mitral perivalvular leaks via a left ventricular apical approach.

Key Points

  • The aim is to accurately assess perivalvular leak (PVL) morphology following mitral valve replacement using imaging technologies.
  • Utilized real-time three-dimensional transesophageal echocardiography and three-dimensional printing for evaluation.
  • Evaluated a 63-year-old woman with a history of mechanical mitral valve replacement.
  • Adjusted 3D printing parameters based on findings from RT-3D TEE for accurate visualization.
  • RT-3D TEE identified two adjacent perivalvular leaks, while initial 3D printing indicated only one.
  • Successful transcatheter closure of PVLs was performed guided by RT-3D TEE.
  • The combination of RT-3D TEE and 3D printing improved the understanding of complex PVL morphologies.

Structured PICO

P
Population
1 adult (63-year-old woman) with a history of rheumatic heart disease, mechanical mitral valve replacement, tricuspid valvuloplasty, and left atrial reduction, presenting with symptomatic multiple perivalvular leaks (NYHA class III, hemolytic anemia).
I
Intervention
Transcatheter closure of mitral perivalvular leaks via left ventricular apical access using 8 mm and 7 mm symmetric ventricular septal defect (VSD) occluders, guided by real-time three-dimensional transesophageal echocardiography (RT-3D TEE) and 3D printing.
O
Outcome
Successful transcatheter closure of multiple perivalvular leaks with no residual regurgitation and resolution of heart failure symptoms at 6 months.

The integration of real-time 3D TEE and 3D printing provides complementary anatomical detail that can successfully guide transcatheter closure of complex, multiple perivalvular leaks.

Limitations

  • 3D printing has limitations in accurately reproducing subtle anatomical details and hemodynamic properties.
  • Model fidelity depends heavily on material selection and printing techniques.
  • Dynamic changes in annular size throughout the cardiac cycle necessitate careful phase selection when constructing and measuring the virtual annulus.
  • 3D printed model produced by external provider, limiting detailed printing parameters
  • RT-3D TEE is operator-dependent and requires significant expertise
  • Single case report cannot establish correlation between hemodynamic findings and clinical outcomes
  • Focused solely on mitral PVL
  • Lacks quantitative comparison of outcomes between imaging modalities

Abstract

Accurate assessment of perivalvular leak (PVL) morphology following valve replacement remains a significant clinical challenge. Precise characterization of PVL anatomy is essential, as different leak patterns require distinct management strategies. We report a case in which two complementary imaging modalities—real-time three-dimensional (RT-3D) transesophageal echocardiography (TEE) and three-dimensional (3D) printing technology—were successfully utilized to evaluate PVL morphology and guide the subsequent surgical approach. A 63-year-old woman with a history of mechanical mitral valve replacement was found to have a PVL on follow-up transthoracic echocardiography (TTE), but the number and morphology could not be fully determined. Initial 3D printing based on cardiac computed tomography angiography (CTA) depicted only one defect; however, subsequent RT-3D TEE revealed two adjacent leaks. Based on TEE findings, the 3D printing parameters were adjusted, allowing visualization of both leaks. These imaging results informed a tailored interventional strategy, and transcatheter closure of the mitral PVLs was successfully performed via left ventricular apical access under real-time TEE guidance. The synergistic integration of RT-3D TEE with color Doppler and 3D printing technology offers complementary strengths in the morphological assessment of complex or multiple PVLs, highlighting its potential clinical value in selected challenging cases.
