The authors report the case of a 19 year old young man with an aorto-right ventricular fistula caused by a stab wound. The diagnosis was not made initially during surgery to control haemorrhage (left hemothorax due to a damaged internal mammary artery). However, three weeks later, a continuous murmur was detected and the diagnosis established by echocardiography and cardiac catheterisation. The lesions were repaired by open heart surgery under cardiopulmonary bypass. The authors describe the main features of this condition based on their own experience and a review of the literature.

This clinical case series reviews the diagnosis and management of aorto-right ventricular fistulas post-transcatheter aortic valve replacement, highlighting 3 cases. We emphasize early detection, individualized treatment strategies, and the role of multidisciplinary heart teams in achieving favorable outcomes. Comprehensive imaging and procedural planning are crucial for successful intervention and management of this rare complication.

Unlabelled: Aorto-atrial fistula (AAF) and aorto-ventricular fistula (AVF) are a rare, but potentially life-threatening condition, where an anomalous connection forms between the aortic structures and the cardiac atria or ventricles. The exact incidence of this condition is unknown, as are the major precipitating factors and best treatment options. It may be congenital, secondary to conditions such as aortic dissection, infective endocarditis, or valve replacement, or iatrogenic in nature.

A 59-year-old man with a history of severe aortic stenosis with transcatheter aortic valve replacement (TAVR) presented with worsening heart failure. Echocardiography showed a fistula between the aorta and the right ventricle with mild to moderate paravalvular regurgitation. He underwent a valve-in-valve TAVR with symptomatic improvement and decreased flow through the fistula.

Rupture of a sinus of valsalva aneurysm (SVA) and the development of an aorto-right ventricular fistula (ARVF) is a rare condition, associated with high morbidity and mortality rates if left untreated. Opening of the SVA rupture into the right heart chambers may result in various morbidities, such as pulmonary hypertension. We present a case of a patient who developed ARVF following sutureless aortic valve replacement, and was subsequently treated successfully via a percutaneous approach.

Infective endocarditis caused by in patients without a history of intravenous drug abuse and endovascular procedures is rare. We present a middle-aged man with fever, chills, night sweats and dyspnoea for 2 weeks. Physical examination and blood cultures were drawn, and the patient was empirically started on antibiotics.
