We report a case of false aneurysm of the left ventricle occurring subsequently to the placing of a vent sump line through the apex during an aortic valve procedure; the diagnosis was made twelve months later during a routine echocardiographic examination. The lesion was successfully repaired. This case recommend the use of other routes of venting in order to reduce the incidence of such complications.
The lesion was successfully treated under cardiopulmonary by-pass and cardioplegic arrest. The mass was completely isolated, opened and identified as a false aneurysm. It appeared as a 5 cm × 3 cm red sac with free blood inside. The previous site of venting was identified and the cavity connected to the left ventricle (3 mm in diameter) closed with interrupted pledgeted polipropilene sutures. The patient was easily weaned off bypass and was discharged six days later.
Although effective, the apical venting can determine complications such as myocardial injury as well as serious difficulties in closing the vent site.
Because of the severity of the mentioned complication we recommend the use of different routes of left ventricular venting in order to prevent the risk of such complications.
