| Popis: | Congenital left ventricle outpouchings (LVO) are a very rare condition that include left ventricle accessory chamber, left ventricle aneurysm (LVA), left ventricle diverticulum (LVD), double-chambered left ventricle and accessory left ventricle, without well-stablished diagnostic criteria. A recent article by Elaheh Malakan et al tries to show this difficulties and propose an algorithm to help define this different pathologies. We present the case of a 26-day-old boy that was admitted to our Hospital with suspicion of dilated cardiomyopathy. In his physical exam a systolic murmur was detected, and his mother described tiredness during intakes and tachypnea. His ECG showed a sinus rhythm, with an 80º QRS axis. No signs of hypertrophy or dilated cavities were detected. As part of the study a TTE was performed, detecting a dilated left ventricle with a tract crossing the apical side from the LV lateral wall. The MRI confirmed the presence of an incomplete muscular septum from de LV lateral wall up to the apex encompassing the papillary muscles in the mid left ventricle, dividing the LV in two chambers with telediastolic size of 3.5x3cm and 2.6x2.4cm respectively. This secondary appendix, with a pseudoaneurysm morphology, distended in systole with a dyskinetic motion. Globally, the left ventricle was dilated and had mild systolic disfunction. The right cavities were morphological and functionally normal. In this case initially a common dilated cardiomyopathy was suspected, being able to confirm the presence of a muscular tract crossing the mid left ventricle. The MRI described the image as an LV pseudoaneurysm, however the TTE images and the diagnostic algorithm proposed by Elaheh Malakan et al would include this case as a two-chamber left ventricle, denoting the still present difficulties in the diagnostic process in these cases, and its impact in their therapeutic approach.
