- Redo aortic valve surgery in a case of dextrocardia with situs inversus totalis(2022) DINATO, Fabricio Jose; BRANDAO, Carlos Manuel de Almeida; VERONESE, Elinthon Tavares; POMERANTZEFF, Pablo Maria Alberto; JATENE, Fabio BiscegliIntroduction: Dextrocardia is a rare congenital cardiac anomaly where the base-apex axis of the heart is directed to the right side. It may be associated with situs solitus, situs inversus, or situs ambiguous. Such cases are technically challenging when heart surgery is needed. Presentation of case: We presented a case of a patient with dextrocardia and situs inversus totalis, who had severe aortic bioprosthetic valve degeneration needing a redo aortic valve replacement. Our operative strategy was to change the position of the main surgeon to the left side of the patient to perform most surgical steps. Discussion: A meticulous pre-operative surgical plan involving the whole team was very important for a smooth intra-operative course and a favourable outcome. Regarding the position of the main surgeon standing on the left side of the patient, we believed this surgical team arrangement added much to the technical ease for the pro-cedure, since the anatomy was opposite to what our minds are used to. Also, computed tomography scan played a crucial role for a proper preoperative anatomical evaluation and surgical planning. Conclusion: Our approach with the surgeon on the left side provided excellent exposure for redo aortic valve replacement in dextrocardia with situs inversus totalis. This surgical management played an important role for the good result in this technically challenging scenario.
- Partial pericardiectomy for refractory acute tuberculous pericarditis: A case report(2023) FERNANDES, Andre Loureiro; DINATO, Fabricio Jose; VERONESE, Elinthon Tavares; BRANDAO, Carlos Manuel de Almeida; AIELLO, Vera Demarchi; JATENE, Fabio BiscegliIntroduction: Tuberculosis is an infectious disease that usually manifests in the lungs but can also affect other organs, including the cardiovascular system. In this article, we present a rare case of purulent pericarditis caused by Mycobacterium tuberculosis. Presentation of case: A 67-year-old man was admitted to the emergency department with a large pericardial effusion with evidence of cardiac tamponade caused by acute pericarditis. The patient underwent surgical pericardial drainage, and a total volume of 500 mL of purulent fluid was collected with a positive culture for Mycobacterium tuberculosis. Despite antituberculous drugs, the patient presented with clinical worsening and recurrence of large pericardial effusion. Therefore, he was submitted to a second intervention by full median sternotomy to drain the pericardial effusion and perform a surgical pericardial debridement associated with a partial pericardiectomy. After the procedure, he improved clinically and was discharged after 24 days of hospitalization. Discussion: Pericardiectomy is recommended for patients with refractory tuberculous pericarditis after four to eight weeks of antituberculous treatment. We decided not to wait that long to perform an open surgical partial pericardiectomy and debridement with a median sternotomy approach. We believe that this more aggressive surgical approach would be more efficient to combat the infection, which was causing progressive deterioration of patient's clinical condition and early recurrence of significant pericardial effusion.Conclusion: Open partial pericardiectomy with surgical debridement could be an efficient approach for treatment of a refractory acute tuberculous pericarditis.
