Dilated Inferior Vena Cava: A Common Echocardiographic Finding in Highly Trained Elite Athletes

Typical structural features of the athlete’s heart as defined by echocardiography have been extensively described; however, information concerning extracardiac structures such as the inferior vena cava (IVC) is scarce. Fifty-eight top-level athletes and 30 healthy members of a matched control group...

Zusammenfassung:	Typical structural features of the athlete’s heart as defined by echocardiography have been extensively described; however, information concerning extracardiac structures such as the inferior vena cava (IVC) is scarce. Fifty-eight top-level athletes and 30 healthy members of a matched control group underwent a complete Doppler echocardiographic study. IVC diameter was determined in the subxiphoid approach 10 to 20 mm away from its junction to the right atrium. Measures reflect the median values between maximal inspiratory and expiratory values. IVC respiratory collapsibility index was determined as well. IVC in athletes was 2.31 ± 0.46 cm compared with 1.14 ± 0.13 cm in the control group ( P < .001). Swimmers had an IVC diameter of 2.66 ± 0.48 cm compared with 2.17 ± 0.41 cm in other athletes ( P < .05). The IVC was normal (
