An unusual cause of diastolic mitral regurgitation as a result of sterile perforation of the mitral valve.
We report the case of a 50-year-old man in whom a supracristal ventricular septal defect led to aortic regurgitation and, thus, to consecutive sterile perforation of the anterior mitral leaflet, culminating in the development of severe systolic and diastolic mitral regurgitation. Aortic regurgitation as a result of valve prolapse caused by a supracristal (conal) ventricular septal defect is a well-known phenomenon. The same is true for the origin of mitral jet lesions in patients with infective endocarditis of the aortic valve. As of yet, there have been no reports about the acquisition of mitral valve perforations in patients without the history of vegetations. Moreover, the occurrence of diastolic mitral regurgitation is usually associated with atrioventricular pressure reversal, a phenomenon that was not present in our patient. The unique comorbidity was easy to detect with Doppler echocardiography, supported by transesophageal 2-dimensional and dynamic 3-dimensional echocardiography for preoperative surgical treatment.
