Mini Thoracotomy

A right mini-thoracotomy approach may be used for mitral valve repair without compromising clinical outcomes. Compared with conventional sternotomy, there is an increased distance to the cardiac structures from the mini-thoracotomy incision, which makes certain technical acts more demanding. One particular challenge is hemostasis at the antegrade cardioplegia cannula site. We propose a novel technique to remove an antegrade cardioplegia cannula using the COR-KNOT system. This technique negates the need for tying with a knot pusher and reduces the risk of aortic injury and troublesome bleeding.

Clinical Benefits

Microinvasive, catheter-based mitral valve repair of severe mitral regurgitation utilizes less invasive approaches with less procedural morbidity and mortality. The procedural steps and clinical benefits of the transcatheter transapical mitral valve annuloplasty (AMEND mitral repair implant) and transcatheter transapical chordal repair systems (Neochord DS 1000 device and Harpoon Mitral Valve Repair System) are reviewed in this manuscript.

Abstract OBJECTIVES Mitral valve repair is the preferred method used to address mitral valve regurgitation, whereas transcatheter mitral valve repair is recommended for high-risk patients. We evaluated the risk-predictive value of the age-adjusted Charlson comorbidity index (aa-CCI) in the setting of minimally invasive mitral valve surgery. METHODS The perioperative course and 1-year follow-up of 537 patients who underwent isolated or combined minimally invasive mitral valve surgery were evaluated for 1-year mortality as the primary end point and other adverse events. The predictive values of the EuroSCORE II and STS score were compared to that of the aa-CCI by a comparative analysis of receiver operating characteristic curves. Restricted cubic splines were applied to find optimal aa-CCI cut-off values for the increased likelihood of experiencing the predefined adverse end points. Consequently, the perioperative course and postoperative outcome of the aa-CCI ≥8 patients and the remainder of the sample were analysed. RESULTS The predictive value of the aa-CCI does not significantly differ from those of the EuroSCORE II or STS score. Patients with an aa-CCI ≥8 were identified as a subgroup with a significant increase of mortality and other adverse events. CONCLUSIONS The aa-CCI displays a suitable predictive ability for patients undergoing minimally invasive mitral valve surgery. In particular, multimorbid or frail patients may benefit from the extension of the objectively assessed parameters, in addition to the STS score or EuroSCORE II. Patients with an aa-CCI ≥8 have a very high surgical risk and should receive very careful attention.

Objective: To identify echocardiographic and surgical risk factors for failure after mitral valve repair. Methods: We identified a total of 77 consecutive patients from our institutional mitral valve surgery database who required redo mitral valve surgery due to recurrence of mitral regurgitation after primary mitral valve repair. A control group of 138 patients who had a stable echocardiographic long-term result was included based on propensity score matching. Systematic analysis of echocardiographic parameters was performed before primary surgery; after mitral valve repair and prior to redo surgery. Risk factor analysis was performed using multivariate Cox regression model. Results: Redo surgery was associated with the presence of pulmonary hypertension ≥ 50 mmHg (p = 0.02), a mean transmitral gradient > 5 mmHg (p = 0.001), left ventricular ejection fraction ≤ 45% (p = 0.05) before surgery and mitral regurgitation ≥moderate at time of discharge (p = 0.002) in the whole cohort. Patients with functional mitral valve regurgitation had a higher tendency to undergo redo surgery if preoperative left ventricular end-diastolic diameter exceeded 65 mm (p = 0.043) and if postoperative tenting height exceeded 6 mm (p = 0.018). Low ejection fraction was not significantly associated with the need for redo mitral valve surgery in the functional subgroup. Conclusions: Recurrent mitral regurgitation is still a valuable problem and is associated with relevant perioperative mortality. Patients with severe mitral regurgitation should undergo early mitral valve repair surgery as long as systolic pulmonary artery pressure is low, left ventricular ejection fraction is preserved, and LVEED is deceeds 65 mm.
