Description
  • A 59-year-old woman was referred to our hospital for evaluation of chest pain and dyspnea. On transthoracic echocardiography, a left atrial mass suggestive of myxoma was detected (Figure 1A). To evaluate the vascularization of the left atrial mass, venous infusion (1 mL/min) of a third-generation echocardiographic contrast agent (Sono Vue, Bracco, Italy) was subsequently combined with a new contrast-specific imaging technique (%22power modulation imaging,%22 Phillips Medical Systems, Eindhoven, the Netherlands). With conventional diagnostic ultrasound, gas-filled microbubbles, the main components of echocardiographic contrast agents, are destroyed by high acoustic power (mechanical index usually >0.8) and tissue perfusion cannot be continuously imaged. Power modulation imaging, on the other hand, allows for marked reduction of transmission power (mechanical index 0.1 in the present study), resulting in tissue microbubble concentrations unequivocally above the detection threshold of the imagin
