Male 8 years old Reason: Ao root dilatation Left VentricleThe left ventricle is normal in size. There are no regional wall motion abnormalities present. There is no late gadolinium enhancement to suggest the presence of an underlying fibrosing, infiltrative, or inflammatory process. Global LV function is normal.Left AtriumThe left atrium is normal in size. Right VentricleThe right ventricle is normal in size. Right AtriumThe right atrium is normal in size. Aortic ValveThe aortic valve opens widely. There is dephasing inferior to the aortic valve suggesting aortic regurgitation. Mitral ValveThe mitral valve opens widely. There is no significant mitral regurgitation. Dedicated through plane imaging of the mitral valve was not performed.Pulmonic ValveThe pulmonic valve opens widely. There is no significant pulmonic regurgitation visualized. Dedicated through plane imaging of the pulmonic valve was not performed.Tricuspid ValveThe tricuspid valve opens widely. There is mild tricuspid regurgitation visualized. Dedicated through plane imaging of the tricuspid valve was not performed.AortaStatus post transposition correction (arterial switch correction, LeCompte maneuver). The ascending thoracic aorta is dilated. There is a left sided aortic arch. The right coronary artery arises from the posteriorly rotated right sinus of Valsalva and branches normally. The left coronary artery, arises from the anterior left sinus of Valsalva and courses posteriorly in between the aortic root and the left atrial appendage with no intramural portion or evidence of compression and branches normally.AORTA MEASUREMENTS: aortic valve ring: 18 mmsinuses of Valsalva: 38.5 mmsinotubular junction: 11.3 mmascending aorta: 14 mmaortic arch: 11 mmdescending aorta: 11.7 mmdiaphragmatic hiatus: 14 mmAORTA FLOW QUANTITATION: Stroke volume in ml: 40.3 Forward flow volume in ml: 74.8Backward flow volume in ml: 34.5Regurgitant factor in %: 46.1Pulmonary ArteryStatus post transposition correction (arterial switch correction, LeCompte maneuver). The main pulmonary artery is normal in size. The left pulmonary artery appears to be mildly narrowed, however flow quantification measurements demonstrate equal flow to the right and left pulmonary branches.PULMONARY ARTERY MEASUREMENTS:MAIN: 17 mmRIGHT: 13.4 mmLEFT: 8 mmPULMONARY ARTERIES FLOW QUANTITATION:Main pulmonary arteries flow quantitation values are as follows:Stroke volume in ml: N/AForward flow volume in ml: N/ABackward flow volume in ml: N/ARegurgitant factor in %: N/ARight pulmonary artery flow quantitation values are as follows:Stroke volume in ml: 17.2Forward flow volume in ml: 20Backward flow volume in ml: 2.72Regurgitant factor in %: 13.6Left pulmonary artery flow quantitation values are as follows:Stroke volume in ml: 19.6Forward flow volume in ml: 19.7Backward flow volume in ml: 0.1Regurgitant factor in %: 0.6Venous AnatomyThe SVC and IVC are normal in size and drain normally into the right atrium. PericardiumThere is no pericardial thickening or effusion.
1. Status post arterial switch operation.2. Normal right and left ventricle function. 3. Significant aortic root dilatation (38 cm in diameter), significant aortic valve insufficiency.4. Particular coronary anatomy as described above.5. Normal cardiac viability, no evidence of intracardiac shunt.Dr. Peter Varga was present during the elaboration of this report and agrees with the findings.
