Cyanosis other imaging findings

❑ Obtaining hemodynamic and anatomic data at the time of intervention

❑ Assessment of pulmonary resistance and reversibility of pulmonary hypertension in patients with CHD or primary pulmonary hypertension for surgical procedure or medical decisions
❑ Assessment of complex pulmonary atresia for determination of lung segmental pulmonary vascular supply, especially when noninvasive imaging are inadequate
❑ Determination of coronary circulation in pulmonary atresia with intact septum
❑ Follow-up of graft vasculopathy after cardiac transplantation

❑ Assessment of patient before cardiac transplantation

❑ Determination of pulmonary pressure/resistance and transpulmonary gradient in palliated single-ventricle patients before a staged Fontan procedure
❑ Assessment of cardiomyopathy or myocarditis
❑ Assessment of suspected congenital coronary artery anomalies

❑ In any CHD patient in whom complete diagnosis and information cannot be obtained by noninvasive testing
❑ Assessment of anatomy and hemodynamics in postoperative cardiac patients when the early postoperative course is unexpectedly complicated and noninvasive imaging techniques ( cardiac MRA, cardiac CT angiography) fail to diagnose
