Anorexia nervosa (AN) is an eating disorder that most frequently afflicts females in adolescence. In these subjects, cardiovascular complications are the main cause of morbidity and mortality. Aim of this review is to analyze the hemodynamic, pro-arrhythmic and structural changes occurring during all phases of this illness, including re-feeding. A systematic literature search was performed on studies in the MEDLINE database, from its inception until September 2017, with PUBMED interface focusing on AN and cardiovascular disease. This review demonstrated that the most common cardiac abnormalities in AN are bradycardia and QT interval prolongation, which may occasionally degenerate into ventricular arrhythmias such as Torsades des Pointes or ventricular fibrillation. As these arrhythmias may be the substrate of sudden cardiac death (SCD), they require cardiac monitoring in hospital. In addition, reduced cardiac mass, with smaller volumes and decreased cardiac output, may be found. Furthermore, mitral prolapse and a mild pericardial effusion may occur, the latter due to protein deficiency and low levels of thyroid hormone. In anorectic patients, some cases of hypercholesterolemia may be present; however, conclusive evidence that AN is an atherogenic condition is still lacking, although a few cases of myocardial infarction have been reported. Finally, refeeding syndrome (RFS), which occurs during the first days of refeeding, may engender a critically increased risk of acute, life-threatening cardiac complications.

Osteopetrosis is a rare hereditary bone development disorder caused by osteoclast dysfunction, which increases bone density. Although few studies have investigated cardiovascular disease in osteopetrosis, sternotomy outcomes in this condition are unclear. We report the case of a patient with osteopetrosis and severe mitral regurgitation. A 63-year-old woman with exertional dyspnea had regurgitant systolic murmur audible at the apex. Transthoracic echocardiography showed severe mitral regurgitation due to posterior leaflet prolapse on the anterolateral side. Radiological findings revealed increased bone density (consistent with osteopetrosis). Considering risks in median sternotomy, we performed minimally invasive cardiac surgery through right minithoracotomy for mitral regurgitation. Preoperative imaging showed sclerotic rib changes; nevertheless, sufficient surgical views obtained involved the intercostal space. No residual mitral regurgitation was observed, and the postoperative course was good. To the best of our knowledge, this is the first case report on minimally invasive cardiac surgery for mitral regurgitation with osteopetrosis.
