I will like to keep EACTA informed of the progress towards UK accreditation in TOE training. The syllabus is in line with the EACTA TOE training course, in that some TTE is included. Under the auspices of the BSE (British Society of Echocardiography) we have made the following the components of TOE training. During an 24 month period the candidate must:

He admitted to having had a murmur since childhood but that it was ‘nothing to worry about’. His transthoracic echo (TTE) suggested a right atrial mass. He then had a TOE performed which was reviewed and gave a differential diagnosis of ; atrial myxoma/thrombus, tricuspid endocarditis (but no history of substance abuse) and ruptured sinus of Valsalva. Finally the patient went to the operating room after failure to improve medically. The TOE was repeated after induction and reveals the diagnosis. Answer now to gain marks. No mar for ‘endocarditis’ without more detail! Standard teaching is that TTE is the appropriate investigation for ventricular septal defects and that TOE only adds information about valvular function. However some authors would disagree (1). ![]() Fig 1 ![]() Fig 2 In Figure 1 the TOE frame shows a mass in the region of the septal tricuspid leaflet. Even when the image is moving it is hard to be sure if this is originating from the valve itself or is indeed an atrial mass protruding into the right ventricle. This is not the right view for a ruptured sinus of Valsalva. Thus given the history a the mass seems likely to be a vegetation. But where from? Figure 2 reveals a sub-aortic jet, into the right ventricle. This is therefore a congenital membranous ventricular septal defect which has become the sight of infection. Surgery confirmed this, removed the vegetation and closed the hole. The patient made a full recover with an intact tricuspid valve. |
