Key result
Correction of atrioventricular disjunction using an extended bovine pericardium patch showed lower mortality compared to mitral annulus fixation with bovine pericardial strips.
Why the study?
The study compared the mortality rates of two surgical techniques for the correction of atrioventricular disjunction occurring during mitral valve replacement.
Does a bovine pericardium patch technique reduce mortality compared to fixing the mitral annulus with bovine pericardial strips in patients with atrioventricular disjunction undergoing mitral valve replacement?

Does a bovine pericardium patch technique reduce mortality compared to fixing the mitral annulus with bovine pericardial strips in patients with atrioventricular disjunction undergoing mitral valve replacement?
A surgical technique using a bovine pericardium patch extending from the papillary muscles to the left atrium may reduce mortality in patients with atrioventricular disjunction undergoing mitral valve replacement compared to simple annular fixation.

Extended patch technique was associated with lower mortality; hypothesis-generating and requires randomized confirmation before practice change.
We compared the mortality rates of two surgical techniques for correction of atrioventricular disjunction in 10 out of 720 patients who underwent mitral valve replacement from 2005 to 2012. In group I, the mitral annulus was fixed with bovine pericardial strips; in group II, a 'patch' of bovine pericardium was sutured and extended from the base of the lateral and medial papillary muscles, covered the posterior wall of the left ventricle, went through the posterior mitral annulus, and ended in the posterior wall of the left atrium adjacent to the mitral ring. The group II technique showed a lower mortality.

Pires et al. (2020) conducted a cohort in Atrioventricular disjunction (n=10). Extended bovine pericardium patch technique vs. Mitral annulus fixation with bovine pericardial strips was evaluated on Mortality. Correction of atrioventricular disjunction using an extended bovine pericardium patch showed lower mortality compared to mitral annulus fixation with bovine pericardial strips.
