Target follow-up type
Description of intervention(s) / exposure
The treating anaesthetist will conduct their preoperative clinical assessment and will record their diagnosis and management plans on the research case report forms.
An independent anaesthetist trained in performing TTE (Trans-Thoracic Echocardiography), and not involved directly in patient care, will perform a goal focused TTE (HART scan)
The treating anaesthetist will be shown the forms and findings will be explained to them. The anaesthetist performing the TTE will not provide any opinion on management, but solely describe the findings to the treating anaesthetist
The treating anaesthetist will complete a second management form (which is identical to the pre TTE form).
Any adverse intraoperative events will be recorded (these are defined below)
Postoperative mortality, major adverse cardiac events and NYHA status will be recorded at 1, 6 and 12 months after surgery by patient interview and medical record review. lung scan and record their findings on the case report forms.
The TTE and lung scan will take 15min and be performed once.

Outcomes
Primary outcome [1] 288691 0
Preoperative focused TTE by an independent anaesthetist changes the:
a.     diagnosis of haemodynamically significant cardiovascular disease, haemodynamic state or presence of pulmonary oedema made by the treating anaesthetist >30%
b.     management plan of the treating anaesthetist or surgeon by >30%
compared to prior clinical assessment.
A standardized form will be used and variation from planned anaesthetic will be note post TTE/Lung scan
Timepoint [1] 288691 0
pre-operatively
Secondary outcome [1] 300770 0
Identify the incidence and distribution of clinically significant cardiovascular disease, abnormal haemodynamic state (including pulmonary hypertension, RVSP>60 mm Hg) and pulmonary oedema and pleural effusions.
Timepoint [1] 300770 0
This will be determined by the TTE/Lung scan and the treating anaesthetist informed pre-operatively
Secondary outcome [2] 300771 0
Incidence of vasodilated haemodynamic state and compare to the time interval after last haemodialysis.
Timepoint [2] 300771 0
pre-operatively at the time of the TTE/lung scan
