ECG showed atrial fibrillation. Transthoracic echocardiography reveal\u00a0ed severe tricuspid regurgitation, preserved left and right ventricular systolic function, slightly elevated systolic pulmonary artery pressure and an abnormal chamber-like structure (see\u00a0online supplementary\u00a0video A). Hence, transoesophageal echocardiography (TE) was performed (figure 1, see\u00a0online supplementary\u00a0video B).<\/jats:p>\n                  <jats:supplementary-material id=\"SP1\"
