Original publication title: Development of Spontaneous Echocardiographic Contrast After Transarterial Occlusion of a Patent Ductus Arteriosus in an Adult Dog With Concurrent Pulmonary Hypertension.

Plain-English summary
An 8-year-old female Chihuahua was brought in for evaluation of a heart condition called patent ductus arteriosus (PDA), which was causing her heart to enlarge and leading to breathing problems due to pulmonary hypertension. The vet performed a procedure to close the PDA, which initially caused a temporary drop in heart function. However, the next day, tests showed no remaining ductal flow, but there was a new finding of spontaneous echocardiographic contrast in her left ventricle. After treatment with medications to support her heart and blood flow, a follow-up five weeks later showed that the contrast had resolved, indicating improvement in her condition.

Abstract
An 8-year-old intact female Chihuahua was presented for evaluation and possible occlusion of a previously diagnosed patent ductus arteriosus (PDA). Transthoracic echocardiography revealed left ventricular and left atrial enlargement, enlargement of the main pulmonary artery, and a PDA with bidirectional shunting. Tricuspid regurgitant velocities suggested moderate pulmonary hypertension. The PDA was occluded with an Amplatz® Canine Duct Occluder using a transarterial approach on the following day. No immediate complications were observed other than an acute decrease in left ventricular systolic function. One day after the PDA occlusion transthoracic echocardiography revealed no residual ductal flow, but there was spontaneous echocardiographic contrast in the left ventricle. The patient was discharged with sildenafil, pimobendan, and clopidogrel. Five weeks later when the patient was presented for a recheck examination, the previously documented spontaneous echocardiographic contrast was no longer present. Finding spontaneous echocardiographic contrast in the dog has not previously been reported in association with PDA occlusion.
