Complex Decision

Cardiac diverticula represent an extremely rare but serious cause of cardiac morbidity and mortality. They can result to arrhythmia, sudden cardiac death and ventricular dysfunction but may have no pathological implications. Here is a case of a 60-year-old Maori farmer with both rheumatic mitral valve disease and left ventricular (LV) septal diverticulum. The requirement for mitral valve replacement raised the complex decision of whether to undergo concurrent diverticulum repair. The haemodynamic significance of the diverticulum was impossible to ascertain, although we could not in good conscience leave such a large diverticulum with potential to influence further systolic deterioration. Three months after the procedures, the patient developed severe tricuspid regurgitation which is a first reported association postseptal diverticulum repair. The case highlights that careful consideration is required in repairing LV septal diverticula and an emphasis should be placed on complications and the requirement for repeat surgery during the consent process.

The morphological changes that occur in myxomatous mitral valve disease (MMVD) involve various components, ultimately leading to the impairment of mitral valve (MV) function. In this context, intrinsic mitral annular abnormalities are increasingly recognized, such as a mitral annular disjunction (MAD), a specific anatomical abnormality whereby there is a distinct separation between the mitral annulus and the left atrial wall and the basal portion of the posterolateral left ventricular myocardium. In recent years, several studies have suggested that MAD contributes to myxomatous degeneration of the mitral leaflets, and there is growing evidence that MAD is associated with ventricular arrhythmias and sudden cardiac death. In this review, the morphological characteristics of MAD and imaging tools for diagnosis will be described, and the clinical and functional aspects of the coincidence of MAD and myxomatous MVP will be discussed.

Functional mitral regurgitation, which occurs as a consequence of regional of global left ventricular or global left ventricular dysfunction despite structurally normal mitral valve (MV), is a common complication in patients with ischemic or non-ischemic cardiomyopathies [1].
