Coronary Computed Tomography Angiography in Combination with Coronary Artery Calcium Scoring for the Preoperative Cardiac Evaluation of Liver Transplant Recipients

Table 1

Clinical applications of CCTA in combination with the CACS in LT candidates.

Study	Patients; ()	Positive criteria; positive patients, (%)	Clinical outcomes
Jodocy et al. [24]	54	CACS > 300 or > 50% stenosis on CCTA; 24 (44%)	CCTA and CACS are useful tools for perioperative cardiovascular risk assessments.
Cassagneau et al. [10]	52	> 50% stenosis on CCTA; 6 (12%)	The prognostic value of CCTA is comparable to dobutamine stress echocardiography.
Chae et al. [11]	247	Mild to moderate involvement on CCTA; 27 (11%)	CCTA should be included in routine pretransplant cardiac workups.
Kemmer et al. [25]	85	CACS > 100; 30 (35%)	CACS is a valid alternative tool for risk stratification of LT candidates.
Kong et al. [20]	443	CACS > 400; 11 (3%)	CACS > 400 is a predictor of cardiovascular complications following LT.
Poulin et al. [26]	100	≥ 70% stenosis on CCTA and/or CAG; 20 (20%)	Using CCTA in the evaluation of LT candidates is challenging but is feasible and safe.
