Coronary bypass and mitral repair: surgical treatment in a HFrEF patient

Coronary bypass and mitral repair: surgical treatment in a HFrEF patient
Title Case presentation

    A 60-year-old male patient (170cm, 84kg, BMI 29kg/m²) with a history of type 2 diabetes mellitus presented for follow-up of known myocardial dysfunction. He reported mild symptoms, including reduced exercise tolerance. Given his risk profile – including dyslipidemia, family history of coronary artery disease, and diabetes - a coronary angiogram was recommended.

    Contenu

    His past medical history included:

    Type 2 Diabetes Mellitus, onset in 2021
    HbA1c 7% under medication with Metformin and Abasaglar
    Suspected diabetic polyneuropathy
    Bilateral mediasclerosis

    Current echocardiographic findings:

    • Left ventricular hypertrophy
    • Hypokinesia of the basal inferior, posterior, and septal segments; hypokinesia of the mid-lateral and mid-posterior segments
    • Eccentric mitral valve insufficiency of grade I–II

    Aortic sclerosis with a small plaque
    Cardiovascular risk factors (CVRF): Dyslipoproteinemia, family history of coronary artery disease (CAD)
    Small axial hiatal hernia

    Contenu

    Medications: 

    Meformin: 500 mg 1-0-1
    Abasaglar: 0-0-0-14IE
    Semaglutid (was added currently): 0,25mg s.c.1x per week
    Atorvastatin 20mg: 0-0-1
    Ranexa 375mg: 1-0-1
    Vit. D 2000IE: 1-0-0

    Angio and echo

    Coronary angiography revealed a severe three-vessel disease with severe proximal LAD stenosis, severe proximal circumflex artery stenosis, and RCA occlusion with retrograde perfusion (10th June 2025). Echocardiography showed a mild left ventricular hypertrophy, ejection fraction 43%, very eccentric mitral regurgitation (uncertain grading).
