Abstract

Saw tooth cardiomyopathy (STC) is an extremely rare myocardial disorder, with fewer than 14 cases reported since its initial description in 2009. It is defined by distinctive myocardial projections resembling a saw tooth pattern on cardiac MRI. No consistent genetic or pathological abnormalities have been identified. Cardiac MRI with late gadolinium enhancement remains the diagnostic standard. Reported associations include apical aneurysm, patent foramen ovale, mitral valve prolapse, and myocardial bridging. We report a rare case of STC associated with a parachute mitral valve—an association not previously described—broadening the phenotypic spectrum of this under-recognized cardiomyopathy.
