• Good image quality
• Anatomic rendering
• Better diagnostic yield
• Unprecedented
quantitation
• Monitoring procedures
3D Echo scanner
3DE IN VALVULAR HEART DISEASE
• 31-year-old woman • MV “incidentaloma” at
transthoracic echo • Sent for TEE
3DE IN VALVULAR HEART DISEASE
Rapid solving of unclear structures

Tricuspid Regurgita>on: Which Mechanism?
TRV max = 2.8 m/s
• 76 year-old lady • Sclerodermia • Pacemaker implantation 10 months before • Known moderate TR • Admitted for decompensated right heart failure
3D PRINTING OF TRICUSPID VALVE USING 3DTTE
Muraru D et al. ESC 2015
Total time for generating the 3D model of TV was 30 min
• The tangible 3D model of TV
enhanced the perception of the complex 3D shape of the TV and of the non-planarity of TV annulus
3D PRINTING OF TRICUSPID VALVE USING 3DTTE
• This technique could be potentially integrated in clinical practice to assist the
surgical planning and education, and the simulation of the outcomes of various percutaneus TV interventions
Muraru D et al. ESC 2015; EuroEcho 2015
3DE IN VALVULAR HEART DISEASE
Assessing outcome after valve procedures
• 75 year-old lady • percutaneous closure of periprosthetic leak 6 months before • dyspnea at minimal exertion • haemolysis
