The nuclear stethoscope.

Abstract

Eighty consecutive patients undergoing radionuclide gamma camera studies for the measurement of ejection fraction were also examined with the nuclear stethoscope. Overall, the correlation coefficient relating these two techniques was acceptable (r = 0.85). However, two groups were identified: patients with symmetrical wall motion had an excellent correlation (r = 0.90) while patients with regional wall motion abnormalities had a poor correlation (r = 0.78). In conclusion, the nuclear stethoscope is a clinically useful device for monitoring left ventricular function in patients with symmetrical wall motion.

Left-ventricle myocardium segmentation using a coupled level-set with a priori knowledge.

This paper presents a coupled level-set segmentation of the myocardium of the left ventricle of the heart using a priori information. From a fast marching initialisation, two fronts representing the endocardium and epicardium boundaries of the left ventricle are evolved as the zero level-set of a higher dimension function. We introduce a novel and robust stopping term using both gradient and region-based information. The segmentation is supervised both with a coupling function and using a probabilistic model built from training instances. The robustness of the segmentation scheme is evaluated by performing a segmentation on four unseen data-sets containing high variation and the performance of the segmentation is quantitatively assessed.

Left ventricular assist system through the left ventricle for acute myocardial infarction: report of a case.

A 49-year-old man, who had suffered from acute myocardial infarction due to left main trunk occlusion, developed cardiogenic shock and was successfully treated with an implantation of a left ventricular assist system with left ventricular apical drainage. At present he is awaiting a heart transplant at approximately 485 days since the operation. The timely application of a left ventricular assist system before the development of multiple organ failure is thus considered to be effective for patients demonstrating acute myocardial infarction with cardiogenic shock.
