PTE Masters is a brilliant website and (almost entirely) one stop teaching resource for perioperative TOE. Hosted by Tommy Birch this website gets 2 thumbs up and is quite simply superb. At full price it can be quite a stretch for most but be on the look out (often after the PTEeXAM) for great discounts. It contains echo video lectures covering the spectrum of paediatric and adult cardiac surgery hundreds of loops and countless previous papers. recommend highly.
