These can all lead to difficulties seating a prosthesis or annuloplasty ring. The posterior mitral annulus or anteriorly the intervalvar fibrous body can be affected. These situations continue to pose a formidable technical challenge to the cardiac surgeon in the operating room. We review the evidence around solutions for these problems with the intent of giving surgeons an overview of techniques to address these issues.

Patients were divided into normal (Group I) and elevated (Group II) cTnI groups. Pre-operative, operative and post-operative data were obtained from our institution's prospectively collected database.

In our experience, MVA alone is inadequate to eliminate mitral incompetence in these patients. We report the 'Down-Under Repair' as an adjunctive concept for the treatment of a subset of patients with restrictive IMR and associated inferobasal left ventricular aneurysm. The 'Down-Under Repair' reduces mitral leaflet restriction by approximating the origin of the posterior papillary muscle towards the mitral annulus. Midterm results demonstrated sustained valvular competence and symptomatic improvement.

Background. Surgical epicardial left ventricular (LV) lead implantation for biventricular pacing ... more Background. Surgical epicardial left ventricular (LV) lead implantation for biventricular pacing has advantages over the transvenous approach in cardiac surgical patients. We investigated the benefit of concomitant prophylactic LV lead implantation during open heart operations and subsequent lead performance after patients with impaired LV function receive a biventricular device.
