Plain-English summary
This report looks at two horses that had heart issues. The first horse was having trouble performing well and showed an unusual area in its heart on an ultrasound. Further tests ruled out a specific heart defect. The second horse had a heart murmur, and tests showed some abnormal blood flow in its heart. The combination of different ultrasound techniques helped identify a small heart defect that wasn't causing significant problems. Overall, the advanced imaging methods used in these cases proved to be very helpful for diagnosing heart conditions in horses.
Abstract
This case report describes the 2-dimensional transthoracic (2D-TTE), 3-dimensional transthoracic (3D-TTE) and intracardiac echocardiographic (ICE) characterization of the fossa ovalis region in 2 horses. The first case was presented for poor performance and showed an anechoic zone in the interatrial septum on 2D-TTE. Based on 3D-TTE a deepened fossa ovalis could be identified and using ICE the presence of an interatrial shunt could be excluded. The second case was referred for a cardiac murmur and the presence of turbulent flow in and around the interatrial septum on 2D-TTE color flow Doppler. The complementary use of 2D-TTE, 3D-TTE, and ICE allowed detailed characterization of a patent foramen ovale, with evidence of a left-to-right shunt in a dorsocranial to ventrocaudal direction with limited hemodynamic implications. These 2 cases underline the feasibility of 3D-TTE and ICE in horses and especially show the added value of ICE in a clinical setting.
