Abstract

Aims: Hypertrophic cardiomyopathy (HCM) patients often develop left--ventricular subendocardial ischaemia, a cause of chest symptoms, despite normal epicardial coronary arteries. The aim of this study was to examine whether ultrasonic tissue characterization or late gadolinium enhancement on cardiac magnetic resonance imaging can detect subendocardial ischaemia in patients with HCM., Methods and Results: Subendocardial ischaemia was quantified on exercise Tc-99m tetrofosmin myocardial scintigraphy in 29 non-obstructive HCM patients with asymmetric septal hypertrophy. Ultrasonic tissue characterization using cyclic variation of integrated backscatter (CV-IB) and late gadolinium enhancement on cardiac magnetic resonance imaging were analysed separately in the right halves and the left halves of the ventricular septum in relation to subendocardial ischaemia. Subendocardial ischaemia was identified in 17 (59%) patients. The ratio of CV-IB in the right-to-left halves of the ventricular septum was significantly higher in patients with subendocardial ischaemia (1.19 ± 0.10) than those without (0.84 ± 0.10, P = 0.04). The optimal cutoff for the detection of subendocardial ischaemia was the ratio of CV-IB >1.0, with a sensitivity of 80%, specificity of 71%, and accuracy of 76%. On the other hand, late gadolinium enhancement was not associated with subendocardial ischaemia in our cohort., Conclusion: Ultrasonic tissue characterization using CV-IB separately in the right and left halves of the ventricular septum, but not late gadolinium enhancement on magnetic resonance imaging, provided useful information in detecting subendocardial ischaemia in patients with HCM. Ultrasonic tissue characterization may be useful in selecting patients who will benefit from medications to relieve chest symptoms.

45. Metastatic chordoma to the left ventricle: A case report.

Author

Harimoto K, Kawasaki T, Sakai H, Murata H, Sakai C, Yamano M, Miki S, and Kamitani T

Abstract

Chordoma is a rare neoplasm of bone that develops from the remnants of the primitive notochord. We present a 78-year-old woman with metastatic chordoma to the left ventricle. She had been diagnosed with sacral chordoma 5 years earlier, and chordoma gradually spread to numerous muscles, the ankle joint of the left leg, bilateral lungs, and the brain, despite repeated surgical excisions and carbon heavy-ion radiotherapy. Positron emission tomography/computed tomography showed an abnormal accumulation in the heart, with features similar to the other metastatic lesions. Transthoracic echocardiography could not provide a clear view of the heart, but multidetector computed tomography revealed that a giant abnormal mass was attached to the apical inferior segment of the left ventricle. The patient stated that she did not want to undergo surgical resection for the cardiac mass. The chordoma has been slowly increasing in size, but she has remained asymptomatic without cardiovascular events for more than a year since the diagnosis of cardiac metastasis. < Learning objective: Multidetector computed tomography provided information not only about the structure morphology of the left ventricular mass, but also about the pathological features using the attenuation values of computed tomography, enabling us to make a diagnosis of a metastatic lesion to the left ventricle from sacral chordoma.>.

46. Silent pulmonary artery dissection in a centenarian.

Author

Abstract

Pulmonary artery dissection is an extremely rare and fatal disease that is difficult to diagnose. We report a case of a 97-year-old woman with heart failure, who was diagnosed as having silent pulmonary artery dissection by chance during transthoracic echocardiography. Surgical treatment for pulmonary artery dissection was not performed, but the patient has been doing well in a sanatorium for more than 2 years, being a centenarian.

Abstract

We report a case of biventricular noncompaction in whom magnetic resonance imaging revealed prominent trabeculations in the right ventricle as in the left ventricle. A 58-year-old man was referred to our hospital complaining of appetite loss and leg edema. Chest radiography showed cardiomegaly without pulmonary congestion. The diagnosis was right ventricular heart failure with congestive liver causing elevated liver enzyme. Transthoracic echocardiography showed prominent trabeculations and deep recesses in the inferolateral wall and apex of the left ventricle with the end-diastolic dimension of 64mm and ejection fraction of 29%. Magnetic resonance imaging demonstrated right ventricular noncompaction which remained unclear on echocardiography. Prominent trabeculations in the dilated right ventricle were confirmed by right ventriculography. The ejection fraction was 23%.
