A 7-week-old male Doberman presented with tachypnea, dyspnea and a VI/VI, left cranial, continuous heart murmur. Thoracic radiographs revealed severe left-sided cardiomegaly, presence of a rounded soft tissue opacity in the caudodorsal aspect of the thoracic cavity and signs of left-sided congestive heart failure. Clinical signs of heart failure were medically controlled. Echocardiography and computed tomography demonstrated a left-to-right shunting patent ductus arteriosus (PDA) in combination with a right-to-left shunting pulmonary arteriovenous malformation (PAVM) between the right main pulmonary artery and the right caudal pulmonary vein. Arterial blood gasses revealed mild hypoxemia. Transcatheter occlusion of the PDA using an Amplatz Canine Duct Occluder was performed. Four months post-operatively, echocardiography showed normal cardiac size and function with complete PDA closure. Thoracic radiographs revealed absence of the rounded opacity and resolution of cardiomegaly and vascular congestion. The PAVM was no longer visualized on repeated computed tomography and the arterial blood gasses were within normal limits. A PAVM connecting a pulmonary artery to a pulmonary vein has only rarely been reported in dogs. This report describes the presence of a congenital PAVM in combination with a PDA in a dog, which has not been previously reported in veterinary medicine.

Introduction And Objectives: Pulmonary vein (PV) isolation is one of the cornerstones of rhythm-control therapy for symptomatic atrial fibrillation (AF) patients. Pulsed field ablation (PFA) is a novel ablation modality that involves the application of electrical pulses causing cellular death, and it has preferential tissue specificity. In this study, we aimed to share a one-year single center experience of AF ablation with PFA.

Pulmonary arteriovenous malformations (PAVM) are characterized by abnormal pulmonary vessels forming arteriovenous shunts that compromise oxygenation of the blood, causing hypoxemia, and predispose to infections and cerebral ischemia. The patient in this case was a 38-year-old male who presented with tachypnea and dyspnea, cyanosis of extremities, and significant digital clubbing. The patient had structural epilepsy secondary to neurosurgery for a cerebral abscess during childhood.

Endovascular intervention is a safe, effective treatment modality in the management of diverse pulmonary vascular pathologies, including acute or chronic thromboembolic disease, pulmonary arteriovenous malformations (pAVMs), pulmonary artery or bronchial artery hemorrhage, and foreign body retrieval. This article reviews indications, contraindications, techniques, and outcomes in endovascular management of common pulmonary vascular pathologies, with the goal of improving operator familiarity and facility with these procedures.

Transcatheter closure (TCC) of certain ventricular septal defect (VSD) subtypes typically requires arteriovenous loop (AVL) formation or retrograde transarterial deployment. Upfront transvenous cannulation from the right ventricle avoids arterial access and loop-related complications. We retrospectively reviewed data of patients who underwent TCC for perimembranous, intraconal, and post-surgical residual VSDs at our institution (January 2019-December 2023).
