ABSTRACT
Background: Aortic valve fenestration (AVF) is a relatively common anatomical variation, while its rupture is a rare cause of aortic regurgitation (AR), especially following coronary angiography. This case report highlights the importance of echocardiographic evaluation and multidisciplinary discussion for the differential diagnosis of fibroelastoma or endocarditis. Case summary: A 66-year-old man presented with acute shortness of breath following coronary angiography for an inferior ST-elevation myocardial infarction. Echocardiography revealed severe aortic regurgitation associated with a filamentous mobile structure on the non-coronary cusp. A multidisciplinary discussion was conducted to determine the cause of the AR, leading to the patient undergoing aortic valve replacement. A gross inspection of the valve confirmed AVF rupture. Conclusion: Iatrogenic AVF rupture following coronary angiography is an exceptionally rare complication. Thorough echocardiographic evaluation plays a significant role in differentiating AVF rupture from other valve pathologies, such as fibroelastoma, Lambl's excrescence, or endocarditis. Echocardiographic features, including a very thin, linear, and flail-like mobile lesion, the paracommissural location, frequent involvement of the non-coronary cusp, and an eccentric jet of the AR, are suggestive of AVF rupture. While medical history and clinical examination contribute to the diagnostic process, definitive diagnosis relies on surgery and anatomopathology.
ABSTRACT
BACKGROUND: Cardiac involvement is an uncommon presentation of hydatid disease. In this study, we aim to analyze the experience of surgical treatment of cardiac and great vessels echinococcosis in our cardiovascular and thoracic surgery department. METHODS: Through a 16-year period, from 2000 to 2015, 27 patients underwent surgery for cardiac and great vessels hydatid disease. The clinical, operative, and postoperative data were analyzed through this retrospective and descriptive study. RESULTS: Most of our patients came from a rural area. The most common symptom was chest pain. The diagnosis was mainly made by transthoracic echocardiography, which has shown the right ventricle as the most frequent location of the disease. All patients received surgical treatment under cardiopulmonary bypass, and only six surgeries were performed without cross-clamping the aorta. Inhospital mortality rate was 7.4%. CONCLUSIONS: Cardiac hydatidosis is a rare but potentially serious condition whose treatment is mainly surgical even for asymptomatic patients owing to its possible fatal complications. The surgery outcomes are usually satisfactory. Follow-up examinations are highly recommended to detect recurrences.
