Abstract

Background: Atrioventricular groove disruption (AVGD) is a rare and severe complication of mitral valve surgery (MVS). Current literature is limited to several case reports and series. Our aim was to analyze outcomes of patients with AVGD after MVS from our tertiary cardiac surgery center. Methods: Between June 2010 and January 2019, 18 patients suffering AVGD were identified in our institutional database and included in our retrospective observation. Preoperative, intraoperative and outcome data were analyzed using IBM SPSS Statistics. Late survival was estimated by using the Kaplan-Meier survival analysis. Results: The mean age of the study population was 76 +/- 5 years. Most common indication for MVS was an isolated mitral valve insufficiency (67%). Severe annular calcification was present in four patients (22%). Majority of implanted valves were biological prosthesis (78%). Due to the location, 72% suffered type I rupture. External repair was performed in 94% of all patients. Second look operation in regard of excessive mediastinal hemorrhage was necessary in 67% of patients. Mean hospital stay of the presented collective was 13 +/- 11 days with an intra-hospital mortality of 56%. Late follow-up was obtained in eight patients at an average of 3.1 (1.6-5.7) years postoperatively. Conclusion: Mortality rates for AVGD after MVS are high. However, way of managing AVGD depends on the underlying type of rupture and should be evaluated in regard of the myocardial damage. Due to the rare occurrence, registry data might help to address more scientific value concerning therapeutic measures and outcomes of this severe complication.
