On this occasion, the patient was in good general condition, acyanotic, cardiac auscultation with a continuous murmur /4 throughout the precordium accompanied by fremitus. [scielo.br]

Systolic flattening of the interventricular septum was present suggesting right ventricular pressure overload (see Additional file 1 ). A large, subarterial VSD was noted beneath the truncal valve (Figure 2 ). [jcmr-online.biomedcentral.com]
