[|Human|] Doctors decalred that due to acute dissection of arota my dad died during the DVR (Arotic and Mitral valve replacement). But, his 2D echo shows Arota artery is normal. Before operation the dosctors said there is no risk. Is there something wrong with the operation.
[|AI|]  Dissection of aorta is rare but a k own side effect of DVR, and yes it's a life-threatening condition, however if the surgeon have adequate exposure of operative field it may be managed.  A pre procedure 2 d echo even if normal, it doesn't rule out the possibility of dissection as it's a procedure related complication.  However, if m very sure the doctors must have tried to salvage your father after dissection was noted, as no surgeon would like to lose his patient.  Hoping this would help bring some closure.
