Simple technique of repair for Barlow syndrome with posterior resection and chordal transfer via minimally invasive approach: primary experience in a consecutive series of 22 patients.

OBJECTIVE: Current techniques for mitral valve repair (MVR) in Barlow's disease require high level of surgical expertise due to a complex anatomy. A novel and simple standardized technique that particularly considers the pathological changes of the mitral valve in Barlow's disease has been developed. METHODS: Between 2009 and 2013, 22 patients underwent minimally invasive MVR for Barlow's disease and severe mitral regurgitation (MR). A simple, standardized technique was applied, including resection of P2 segment of posterior mitral leaflet (PML) with preservation of the shortest chordae, transfer of the preserved chordae to A2, and implantation of a semi-rigid open ring. In 2015, all patients were contacted for follow-up by transthoracic echocardiography (TTE) and interviewed for their clinical status. RESULTS: During follow-up (mean 2.8 ± 1.1 years; 100% complete), one patient died due to abdominal bleeding 4 months after the initial MVR and one patient with severe calcification of PML underwent valve replacement due to recurrence of MR. Among the remaining cohort (mean follow-up 3.0 ± 1.0 years), NYHA class I, II and III was present in 13, 6, and 1, respectively. TTE demonstrated MR grade 0, 1+, or 2+ in 40, 55, and 5%, respectively, with mean and maximum transvalvular gradients ranging at 1.9 ± 1.7 and 4.7 ± 3.3 mmHg, respectively. CONCLUSIONS: A simple and standardized technique facilitates the repair of MR in the presence of Barlow's, simultaneously addressing the height of PML and the position of the anterior leaflet. This technique has proven durable in the mid-term follow-up in our small series and warrants further validation in larger cohorts.

[Inflammatory cardiac diseases by primary extracardial diseases]. / Entzündliche Herzerkrankungen bei primär extrakardialen Erkrankungen.

As systemic immunological disorders, internal diseases in gastroenterology, rheumatology and infectiology can, in addition to the bowels, potentially involve the musculo-skeletal system, the immunological system and heart structures. All structures and functions of the heart can be affected. Pericarditis in lupus erythematosus and chronic inflammatory bowel disease, myocarditis in HIV infection and lyme disease are examples of cardiac manifestations of internal diseases. The pathogenetic causes can be manifold, such as direct cytotoxic effects in HIV or Borrelia burgdorferi infections, induced vasculitis and local activation of coagulation factors as in lupus erythematosus or chronic inflammatory bowel disease. Improved treatment options have led to more long-lasting courses of internal diseases, such as in infectious diseases, lupus erythematosus and chronic inflammatory bowel disease, thus cardiovascular complications such as pericarditis and myocarditis gain increasing importance as a consequence of chronic disease and therapy-related damage.

[Concomitant cardiovascular conditions in intestinal illness]. / Kardiovaskuläre Begleiterkrankungen und Komplikationen bei Darmerkrankungen.

Vascular diseases are not encountered very often in gastroenterology, though in cases of ischemic colitis a coronary heart disease is often present. In addition, heart diseases such as coronary heart disease, atrial fibrillation, and congestive heart failure are important risk factors for ischemic colitis and should be treated to avoid further ischemic episodes of the gut. The most common extraintestinal manifestations of Crohn's disease and ulcerative colitis are observed in the eye, on the skin, and in the liver region. Involvement of the cardiovascular system does not seem to be very common, though systematic epidemiological data on the significance of these extraintestinal complications--which certainly influence the prognosis--are lacking. Other patients with Crohn's disease or ulcerative colitis suffer from vasculitis, which reflects a further manifestation of inflammatory diseases affecting the cardiovascular system. Another important complication is activation of coagulationfactors, especially during active flare-up of intestinal disease; this can result in thromboembolic events. Systematic studies or investigations on the epidemiology of cardiovascular complications are still lacking, so that an overview of the published data is given. Metastatic tumors of the heart are rare, but there are case reports of cardiac metastases in patients with carcinomas of the colon. Carcinoid heart syndrome, another cardial complication of malignant disease, can prejudice the prognosis of patients with neuroendocrine tumors of the gastrointestinal tract.

Chief cell proliferation of the gastric mucosa mimicking early gastric cancer: an unusual variant of fundic gland polyp.

We describe a hitherto unknown lesion of gastric chief cell proliferation mimicking structurally mucosal gastric cancer. The unremarkable cytology of the cells, their very low Ki-67 index, the inclusion of occasional parietal cells and especially ultrastructural evidence of chief cell differentiation proved helpful in the differentiation from early gastric cancer. The exact classification of the alteration remains unresolved. The presence of microcysts suggests that the lesion is a variant of fundic gland polyp formation.
