Extrinsic mechanical iatrogenic right ventricular outflow tract (RVOT) obstruction caused by a left-sided tension pneumothorax. (A) A left pneumothorax is shown on the chest radiograph. (B) Mid-esophageal view of the RVOT on transesophageal echocardiography. A constant diastolic obstruction of the RVOT is present on M-mode. (C) The obstruction is caused by compression on the RVOT by the antero-medial portion of the left pneumothorax as shown on the CAE-Vimedix simulator (CAE Healthcare Inc., Montreal, Canada).
