Background: The management of mitral regurgitation during aortic valve replacement remains a complex question. Secondary mitral regurgitation often improves post-aortic valve replacement without mitral valve surgery, but residual mitral regurgitation can significantly affect long-term outcomes. This study investigates the natural history of mitral regurgitation following isolated aortic valve replacement and identifies prognostic factors for persistent mitral regurgitation. Methods: A retrospective study was conducted on 108 patients who underwent isolated aortic valve replacement. Patients were categorized based on mitral regurgitation improvement. Additionally, patients were divided into patient-prosthesis mismatch and non-patient-prosthesis mismatch groups based on the aortic prosthesis. Preoperative and postoperative echocardiographic data were analyzed. Results: In total, 63% of patients showed mitral regurgitation improvement. The improved functional MR group showed significant reductions in peak and mean transvalvular pressure gradients. In contrast, the patient-prosthesis mismatch group had persistent mitral regurgitation improvement in 59.2% of patients. The non-patient-prosthesis mismatch group exhibited significant structural improvements and a reduction in mitral regurgitation severity in 68.6% of patients. Conclusions: The study shows that aortic valve replacement could significantly improve MR when patient-prosthesis mismatch is avoided. This approach maximizes hemodynamic outcomes, mitigates the risk of residual or worsening mitral regurgitation, and potentially reduces the need for additional mitral valve interventions. © 2024 by the authors.

Mitral valve replacement (MVR) in the presence of the extensive calcification of the mitral annulus is a technical challenge. The heavily calcified annulus can cause great difficulty in the insertion of a prosthetic valve and periprosthetic leakage later on. Vigorous annular decalcification may cause circumflex coronary artery injury, atrioventricular rupture and thromboembolic events. We herein describe a surgical technique for MVR in such cases while focusing on partial decalcification of the posterior mitral annulus and its reinforcement and buttressing with the transferred anterior mitral leaflet (AML). At the same time, the transferred AML supports the posterior annular region and maintains ventricular-annular continuity, thus preserving the left ventricular function. © The Author 2012.

Right ventricle organized thrombus is a rare pathological condition diagnosed in patients with a risk factor. The most common are right ventricle (RV) failure, autoimmune disease (Behcet disease), hypercoagulable disorder, anaemia, RV pacing leads, pulmonary artery catheters, RV infarction, and ventricular arrhythmogenic cardiomyopathy. The literature describes the impact of iron-deficiency anaemia on thrombosis. We described surgical extirpation of the organized right ventricle outflow tract (RVOT) thrombus in a patient with iron-deficiency anaemia. © 2022, Indian Association of Cardiovascular-Thoracic Surgeons.
