Fig. 1From: Cardiac catheterization addressing early post-operative complications in congenital heart surgery—a single-center experiencea Selective angiography for residual MBT shunt (white asterisk) in a patient after Fallot tetralogy repair; the patient developed heart failure symptoms due to significant left to right shunt. b The same patient after occlusion of the MBT shunt with vascular plug (yellow arrow) with no residual flow seen after aortic angiography. c Significant LPA stenosis (yellow arrow) with decreased left lung vascularity in another patient after Glenn surgery; the patient developed significant desaturation (68–73%) after surgery. d The same patient after LPA stenting (yellow arrow) with the improvement of left lung vascularity and patient saturation increased to 85%.
