HHT: hereditary haemorrhagic telangiectasia; TTCE: transthoracic contrast echocardiography; RLL: right lower lobe; LUL: left upper lobe; LLL: left lower lobe; RUL: right upper lobe; RML: right median lobe; Embolised: PAVM previously treated with embolotherapy. #: number of cardiac cycles when the contrast is first visualised in the left atrium.
