Minimally invasive transapical off-pump chordae implantation includes features such as tachycardia, arrhythmia, hemorrhage, sudden hemodynamic changes caused by the device moving in the left ventricle and the atrium, for anesthetists. In this observational study, the investigators presented the investigators's hemodynamic recuperation and anesthesia experiences revealed by cardiac output measurement after transapical mitral valve repair.

In Sakarya University Educational Research Hospital, perioperative file records of 13 patients who underwent mitral valve repair using the Neochord DS1000 system were retrospectively analyzed. In addition, hemodynamic measurements recorded with the Vigileo Flotrac invasive arterial cardiac output device were evaluated.

Inclusion Criteria:

• All patients that surgical criteria for Neochord implantation with transapical mini-thoracotomy are prolapsus or chordae rupture in posterior, anterior areas or in both leaflets were included.

Exclusion Criteria:

• Exclusion criteria are active endocarditis, functional or ischemic mitral insufficiency (MI), excessive calcific valves, leaflet perforation, anemic dilatation and severe left ventricular dysfunction.
