Specific features and survival of French bulldogs with congenital pulmonic stenosis: a prospective cohort study of 66 cases.

Introduction: The objectives of this study were to characterize the epidemiological, clinical, and echocardiographic features of French bulldogs (FBs) with congenital pulmonic stenosis and document their survival times and risk factors for cardiac death (CD).

Animals: This study included 66 FBs with congenital pulmonic stenosis.

Methods: Prospective cohort study including a survival analysis to assess time to CD.

Successful transcatheter retrieval of embolized Amplatz Canine Duct Occluders in two dogs.

Transcatheter occlusion of patent ductus arteriosus (PDA) using an Amplatz® Canine Duct Occluder (ACDO) is routinely performed in dogs. Pulmonary embolization of the device is a rarely reported complication of this procedure. We report here the first two cases of successful transcatheter retrieval of an embolized ACDO.

Intracardiac echocardiography: use during transcatheter device closure of a patent ductus arteriosus in a dog.

Intracardiac echocardiography (ICE) is used in humans for percutaneous interventional procedures, such as transcatheter device closures. Intracardiac echocardiography provides high-resolution imaging of cardiac structures with two-dimensional, M-mode, Doppler, and also three-dimensional modalities. The present report describes application of ICE during transcatheter occlusion of patent ductus arteriosus using a canine ductal occluder in a dog for which transesophageal echocardiography could not provide an optimal acoustic window.
