ABSTRACT
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.
ABSTRACT
Abstract The cardiac involvement of hydatid cyst, which is rarely seen, with the location of asymptomatic huge cyst in the interventricular septum (IVS) is an extraordinary condition. We report an isolated cardiac hydatid cyst located in the IVS in an 18-year-old man diagnosed incidentally by transthoracic echocardiography. Cardiac magnetic resonance imaging confirmed a mass lesion of 47×74 mm in diameter located at the base of IVS. The cystic content and its germinative membrane were resected and the cavity was applicated under cardiopulmonary bypass. Postoperative course was uneventful and the patient was discharged on the 6th postoperative day, with oral albendazole therapy.

Abstract Objectives: To investigate the association between clinical hematologic parameters and saphenous vein graft failure after on-pump coronary artery bypass surgery. Methods: A total of 1950 consecutive patients underwent isolated on-pump coronary artery surgery between November 2010 and February 2013. Of these, 284 patients met our inclusion criteria; their preoperative clinical hematological parameters were retrospectively obtained for this cohort study. And of them, 109 patients underwent conventional coronary angiography after graft failure was revealed by coronary computed tomography angiography. The primary endpoint was to catch at least one saphenous vein graft stenosis or occlusion following the coronary angiogram. We then analyzed risk factors for graft failure. In sequential or T grafts, each segment was analyzed as a separate graft. Results: In logistic regression analysis, older age, platelet distribution width, and diabetes mellitus were identified as independent predictors of saphenous vein graft failure (P<0.). In contrast, preserved ejection fraction value favored graft patency (P<0.001). Conclusion: Increased platelet distribution width is easily measurable and can be used as a simple and valuable marker in the prediction of saphenous vein graft failure.
