Background: Ischemic mitral regurgitation associated with coronary artery disease presents a management challenge to cardiac surgeons. We report our early and midterm results of chronic ischemic mitral regurgitation treated with concomitant mitral ring annuloplasty and coronary artery bypass grafting.
Methods: We performed a retrospective review of the medical records of patients who underwent coronary artery bypass grafting at our institute from January 2009 to December 2011. Data were collected in 50 patients with chronic ischemic mitral regurgitation who had mitral ring annuloplasty along with coronary artery bypass grafting. Preoperative data, echocardiographic findings, operative procedure, outcome, and perioperative hemodynamics were analyzed. Early and intermediate follow-up data were also collected and analyzed.
Results: There were 3 (6%) early and 9 (18%) late deaths. Of the survivors, 38 (76%) had a significant reduction in left ventricular end-diastolic and end-systolic dimensions and improvement in New York Heart Association functional class.
Conclusion: Despite a risk of residual regurgitation, mitral ring annuloplasty combined with coronary artery bypass appears to be a good treatment option in selected patients with chronic ischemic mitral regurgitation.

Objective: Infective endocarditis (IE) is associated with significant morbidity and mortality and places patients at risk for subsequent peripheral vascular emboli. Our goals were to analyze the incidence of peripheral emboli and their associated complications and outcomes.
Methods: A retrospective single-center review of all patients with IE from 2013-2021 was performed.

Aims: To investigate the distribution of left atrioventricular coupling index (LACI) among patients with heart failure and left ventricular ejection fraction (LVEF)<50% and to explore its association with the combined endpoint of all-cause death or HF hospitalization at long term follow-up.
Methods And Results: Patients with HF and LVEF<50% undergoing cardiac magnetic resonance (CMR) were evaluated. Patients with atrial fibrillation or flutter were excluded.
Association between the proportionality of functional mitral regurgitation and survival after mitral valve operation.

Division of Cardiac Surgery, Yale School of Medicine, New Haven, Conn.
Objective: The concept of proportionate and disproportionate functional mitral regurgitation suggests that transcatheter edge-to-edge mitral repair may benefit patients with a smaller left ventricle relative to a higher regurgitant burden. The clinical relevance of proportionality remains unknown in mitral operations for ischemic mitral regurgitation. We aimed to characterize the association between mitral regurgitation proportionality and outcomes after mitral valve operations.

Objective: To develop a model for preoperatively predicting postcardiotomy cardiogenic shock (PCCS) in patients with poor left ventricular (LV) function undergoing cardiac surgery.
Methods: From the Society of Thoracic Surgeons Adult Cardiac Database, 11,493 patients with LV ejection fraction ≤35% underwent isolated on-pump surgery from 2018 through 2019, of whom 3428 experienced PCCS. In total, 68 preoperative clinical variables were considered in machine-learning algorithms trained and optimized using scikit-learn software.
