Abstract
OBJECTIVE: To evaluate the diameter, perimeter and area of atrioventricular valves as well thickness of ventricular walls and diameter of ventricular cavity of fetal hearts. MATERIALS AND METHODS: Twenty fetal hearts at gestational age between 28 and 36 weeks were dissected. A paquimeter with 1/10 mm accuracy was utilized for the following morphological measurements: anteroposterior and transverse diameters, mitral and tricuspid valves areas and perimeters. RESULTS: Anteroposterior and transverse diameters of the left atrioventricular valve measured 10.35 ± 1.62 mm and 9.90 ± 1.79 mm, respectively; and anteroposterior and transverse diameters of the right atrioventricular valve measured 10.98 ± 1.90 mm and 9.51 ± 1.81 mm, respectively. Mitral valve area and perimeter were, respectively, 84.06 ± 25.09 mm² and 29.87 ± 3.96 mm. Tricuspid valve area and perimeter were, respectively, 84.49 ± 26.79 mm² and 28.44 ± 3.85 mm. The thicknesses of the anterior and posterior right ventricular walls were, respectively, 5.00 ± 1.70 mm and 3.83 ± 0.91 mm. The thicknesses of the anterior and posterior left ventricular walls were, respectively, 4.25 ±0.87 mm and 4.14 ± 0.89 mm. The thickness of the interventricular septum measured 4.10 ± 1.13 mm. The anteroposterior diameter of the right ventricle was 9.25 ± 0.85 mm, and the transverse diameter was 8.24 ± 0.42 mm. The anteroposterior diameter of the left ventricle measured 9.95 ± 0.37 mm, and transverse diameter measured 9.20 ± 0.40 mm. CONCLUSION: The role of morphometric data of fetal atrioventricular valves is highly significant in the echocardiographic diagnosis of possible congenital cardiac malformations.
