Can Obesity Serve as a Barrier to Minimally Invasive Mitral Valve Surgery? Overcoming the Limitations-A Multivariate Logistic Regression Analysis.

Pre-op LVEF was associated with the risk of post-op respiratory failure (OR 0.97, 95% CI 0.96–0.99, p = 0.01), whereas pre-op pulmonary hypertension showed borderline significance as a predictive factor (OR 2.01, 95% CI 0.98–4.09, p = 0.05). - Wound dehiscence and delirium Our logistic regression analysis revealed obesity was not a risk factor for either wound dehiscence or delirium (OR: 1.71, 95% CI: [0.885–3.336], p = 0.11; OR: 1.03, 95% CI: [0.34–3.13], p = 0.95, respectively).

Post-op echocardiography revealed a near-significant higher incidence of grade I MI in the non-obese group (obese: 27 [13.7%] vs. non-obese: 148 [20.0%], p = 0.07), while grade II or higher MI and MS were rarely observed in both groups. 3.3.
