Left ventricular noncompaction

  1. 1. Left ventricular noncompaction
  2. 2. Through ECHO window
  3. 3. 1990-First diagnostic criteria • LVNC  X (distance between epicardial surface and trough of the intertrabecular recesses)  Y (distance between epicardial surface and peak of the trabeculations) If X/Y< 0.5 if it progressively decreased from the papillary muscles toward the apex Chin TK, Perloff JK, Williams RG, Jue K, Mohrmann R. Isolated noncompaction of left ventricular myocardiu. A study of eight cases. Circulation 1990;82:507–13.
  4. 4. 1999-2ND Criteria • LVNC Noncompacted to compacted myocardium ratio needs to exceed a cut-off of 2.3 Ichida F, Hamamichi Y, Miyawaki T, et al. Clinical features of isolated noncompaction of the ventricular myocardium. Long-term clinical course, hemodynamic properties, and genetic background. J Am Coll Cardiol 1999;34:233–40
  5. 5. Other three • Oechslin EN, Attenhofer Jost CH, Rojas JR, Kaufmann PA, Jenni R. Long term • follow-up of 34 adults with isolated left ventricular noncompaction: A distinct cardiomyopathy with poor prognosis. J Am Coll Cardiol 2000;36:493–500. • Belanger AR, Miller MA, Donthireddi UR, Najovits AJ, Goldman ME. New classification scheme of left ventricular noncompaction and correlation with ventricular performance. Am J Cardiol 2008;102:92– 6. • Stanton C, Bruce C, Connolly H, et al. Isolated left ventricular noncompaction syndrome.Am J Cardiol 2009;104:1135–8.
  6. 6. 2014-Latest:All 4 criteria to be fulfilled LVNC 1. Prominent trabeculous formations along the left ventricular endocardial border visible in end-diastole, distinct from papillary muscles, false tendons or aberrant bands 2. Trabeculations move synchronously with the compacted myocardium 3. Trabeculations form the noncompacted part of a two-layered myocardial structure, best visible at end-systole 4. Perfusion of the intertrabecular spaces from the ventricular cavity is present at end- diastole on colour Doppler echocardiography or contrast echocardiography Refinement of echocardiographic criteria for left ventricular noncompaction Claudia Stöllberger,Birgit Gerecke,Josef Finsterer,Rolf Engberding.International Journal of Cardiology 165 (2013) 463–467
  7. 7. Echocardiography  LV short axis  Mid systole  Non compaction to compaction ratio >2  More than 3 recesses  Recesses freely communicates to LV in diastole directly
  8. 8. MRI • End diastole • Non compaction:compaction is >2.3 • Non compaction LV mass>20% of global LV mass
  9. 9. It is so beautiful !
