Left-to-Left Acquired Cardiac Shunt: Aorto-Left Atrial Fistula Due to Aortic Infective Endocarditis in a Dog.

Project description:Infective endocarditis is a severe but rarely diagnosed disease, characterized by the presence of bacterial infection at the level of the cardiac valves. Although the incidence of the disease is very low, the consequences are severe and the prognosis is very poor, outlining a high mortality rate among cases. The present report highlights the case of a 7-year-old dog presented with abrupt changes in the respiratory pattern, obtunded and in lateral recumbency. The physical examination of the patient revealed fever and a IV/VI systolic heart murmur, with the point of maximal intensity on the left hemithorax. Echocardiography identified hyperechoic and cavitary changes beneath the aortic valves and a retrograde turbulent jet originating in the left ventricle outflow tract communicating with the left atrium through a rupture in the aortomitral intervalvular wall. Because of very unstable hemodynamic changes, the dog suddenly died despite the initiation of intensive care supportive treatment, and the postmortem evaluation of the heart confirms the suspicion of infective aortic endocarditis with the development of a paravalvular abscess and an aorto-left atrial fistula.

Aorto-Right Ventricular Fistula Post-Transcatheter Aortic Valve Replacement: Multimodality Imaging of Successful Percutaneous Closure.

Project description:Highlights•Aorto-right ventricular fistula is a rare diagnosis and is on the spectrum of aortic periannular rupture.•Multimodality imaging is crucial in identifying aortic periannular rupture, defining its course, and for preprocedural planning.•We describe a case of aorto-right ventricular fistula, which was successfully treated using an Amplazter vascular plug intravenous device (St. Jude Medical) and is to our knowledge the first reported case of using a plugging device for this type of disorder.

Asymptomatic Aorto-Atrial Fistula Secondary to Surgical Repair of Ascending Aortic Dissection: When to Do Nothing.

Project description:Secondary aorto-atrial fistula is a rare but potentially life-threatening complication of ascending aortic dissection surgical repair. Secondary aorto-atrial fistulas commonly lead to symptomatic heart failure requiring emergent repair. We present a rare case of secondary aorto-atrial fistula after surgical repair of aortic dissection that remained asymptomatic for a decade. (Level of Difficulty: Intermediate.).

Aorto-left atrial fistula: Rare cause of acute cardiac failure in a previously healthy individual.

Project description:Complications of valvular infective endocarditis involving the peri-annular region puts the patient at a significantly high risk of adverse outcomes including heart failure and death. The "mitral-aortic intervalvular fibrosa" is relatively avascular and offers little resistance to the spread of abscesses, aneurysm, and fistula formation. Aorto-cavitary fistulous tract formation in the setting of native valve infective endocarditis is associated with higher rates of heart failure, ventricular septal defect, and atrioventricular block than nonruptured abscesses. Thus, a high index of suspicion is needed for rapid and accurate diagnosis, which can guide further management. A transesophageal echocardiogram is the preferred modality of investigation in such cases. Staphylococci are reported to be the most common pathogen involved. In addition to early antibiotic therapy, prompt surgical intervention might save lives in these scenarios.

Acquired Aorto-Right Ventricular Fistula following Transcatheter Aortic Valve Replacement.

Project description:Transcatheter aortic valve replacement (TAVR) techniques are rapidly evolving, and results of published trials suggest that TAVR is emerging as the standard of care in certain patient subsets and a viable alternative to surgery in others. As TAVR is a relatively new procedure and continues to gain its acceptance, rare procedural complications will continue to appear. Our case is about an 89-year-old male with extensive past medical history who presented with progressive exertional dyspnea and angina secondary to severe aortic stenosis. Patient got TAVR and his postoperative course was complicated by complete heart block, aorto-RV fistula, and ventricular septal defect (VSD) formation as a complication of TAVR. To the best of our knowledge, this is the third reported case of aorto-RV fistula following TAVR as a procedural complication but the first one to show three complications all together in one patient.

Right-to-left shunt due to iatrogenic atrial septal defect manifested by aorto-caval fistula: a case report.

Project description:BackgroundAn aorto-caval fistula is a rare but critical complication of abdominal aortic aneurysm (AAA) rupture, leading to high-output heart failure and increased venous pressure. The anesthetic management of such cases, particularly when complicated by an intraoperative right-to-left shunt, is seldom reported.Case presentationA 71-year-old man with a history of atrial fibrillation and catheter ablation presented with heart failure and abdominal pain, leading to cardiac arrest. Imaging revealed an AAA rupture into the inferior vena cava. During emergency surgery, severe venous bleeding was managed using intra-aortic balloon occlusion (IABO). Transesophageal echocardiography (TEE) identified a right-to-left shunt due to an iatrogenic atrial septal defect.ConclusionEarly TEE recognition and timely IABO intervention were crucial in managing this complex case, underscoring the importance of these techniques in similar emergency scenarios.
