Case Reports[An intermittent mid-diastolic musical murmur indicating aortic regurgitation: report of a case].
An unusual mid-diastolic musical murmur developed soon after cardiac catheterization of a 55-year-old man with mitral stenosis. His physical findings consisted of an accentuated first heart sound, an opening snap and a grade 3/6 mid-diastolic rumbling murmur. No early diastolic murmur was audible. ⋯ The frequency patterns of the murmur and the Doppler signals were identical; therefore, the murmur was judged to be produced by aortic valve vibrations. Furthermore, resonance of cardiac structures which accentuate the murmur might be related to the occurrence of this murmur. Pulsed Doppler echocardiography is helpful in identifying the site of origin of this musical murmur.

Case Reports[Cardiac involvement in systemic amyloidosis: myocardial scintigraphic evaluation].
To assess the clinical significance of technetium-99m-pyrophosphate (Tc-99m-PYP), -methylene diphosphonate (Tc-99m-MDP) and thallium-201 (Tl-201) myocardial scintigraphy in the diagnosis of cardiac amyloidosis and in the differential diagnosis of cardiac diseases, 12 patients with biopsy-proved systemic amyloidosis (seven with familial amyloid polyneuropathy (FAP) and five with primary amyloidosis) were investigated. The results obtained were as follows: In 10 patients (six with FAP and four with primary amyloidosis) studied by Tc-99m-PYP scintigraphy, two (FAP one, primary amyloidosis one) had diffusely positive myocardial uptake, which was of greater intensity than that of the sternum. Six (four FAP; two primary amyloidosis) also had diffusely positive myocardial uptakes, but the intensity was less than that of the sternum. ⋯ Left ventricular hypertrophy was found in six patients and right ventricular visualization in five. Although electrocardiograms in seven of 10 patients showed QS patterns in the right to mid precordial leads, similar to that seen in antero-septal and extensive anterior myocardial infarctions, neither myocardial perfusion defect nor low uptake on Tl-201 images was detected in nine of them. The scintigrams in another one, which showed low uptake at the apical portion of the left ventricle, were considered normal.(ABSTRACT TRUNCATED AT 400 WORDS)
