RESUMEN

Abstract Objective: Sutureless aortic valve replacement (Su-AVR) offers an alternative to supra-annular stented biological aortic prostheses. This single-center study aimed to compare early outcomes after aortic valve replacement with sutureless and conventional stented bioprostheses. Methods: In this retrospective study, we analyzed 52 patients who underwent aortic valve replacement with sutureless and stented bioprostheses between January 2013 and October 2017. Sorin Perceval S sutureless valves were implanted in group 1 and Sorin Mitroflow stented bioprosthetic valves were used in group 2. Postoperative outcomes, including demographics, cardiopulmonary bypass (CPB) times, cross-clamp times, morbidity and mortality, as well as echocardiography in the first month, were compared. Results: Mortality occurred in 1 (3.6%) patient in group 1, and in 2 (8.3%) patients in group 2 (P=0.186). Group 1 had significantly shorter CPB (61.6±26.1 min vs. 106.3±32.7 min, P=0.001) and cross-clamp (30.9±13.6 min vs. 73.3±17.3 min, P=0.001) times. The length of stay in the intensive care unit (1.9±1.3 days vs. 2.4±4.9 days, P=0.598) and hospital stay (7.6±2.7 days vs. 7.3±2.6 days, P=0.66) were similar. Postoperatively, there was no statistically significant difference between the two groups in echocardiography results, and morbidities. The mean aortic valve gradient was 13.5±5.8 mmHg in group 1 and 14.5±8.0 mmHg in group 2 (P=0.634). Paravalvular regurgitation was diagnosed in 3 (10.7%) patients in group 1 and in 1 (4.2%) patient in group 2 (P=0.220). Conclusions: Su-AVR resulted in shorter cross-clamp and CPB times. However, early mortality, postoperative morbidity, and echocardiography results were similar between groups.

RESUMEN

Abstract We are going to present a case of malignant fibrous histiocytoma in the right atrium, which is a very rare entity. The patient had a right atrial mass, which prolapsed through the tricuspid valve into the right ventricle, causing functional tricuspid valve stenosis. The tumor was completely resected and the patient had an uneventful postoperative period. Histopathological examination reported malignant fibrous histiocytoma. The patient presented to the emergency department five weeks after discharge with dyspnea and palpitation. Echocardiography and magnetic resonance imaging revealed recurrent right atrial tumor mass. His clinical status has worsened, with syncope and acute renal failure. On the repeated echocardiography, suspected tumor recurrence was observed in left atrium, which probably caused systemic embolization. Considering the aggressive nature of the tumor and systemic involvement, our Heart Council decided to provide palliative treatment by nonsurgical management. His status deteriorated for the next few days and the patient succumbed to a cardiac arrest on the 4th day.
