“…ICE was originally used to guide noncoronary interventional procedures, such as the electrophysiological procedures, and the closure of interatrial septal abnormalities (20)(21)(22)(23). ICE can clearly show intracardiac structures and devices and there have been several reports discussing ICE-guided cardiac tumor biopsy (24)(25)(26)(27)(28).…”

A 44-year-old man presented with exertional dyspnea. Transthoracic echocardiography (TTE) revealed a large tumor protruding into the right atrium and extending into the left ventricle. Cardiac magnetic resonance imaging and contrast enhanced computed tomography also confirmed the intracardiac tumor detected by TTE. An endomyocardial biopsy was performed under the intracardiac echocardiography (ICE) guidance, and he was diagnosed to have diffuse large B-cell lymphoma following the histological analysis. ICE-guided cardiac tumor biopsy is expected to be a useful diagnostic strategy that can minimize the risk of procedural complications.

“…Furthermore, ICE can guide the biopsy needle and monitor acute complications of the biopsy, such as perforation or bleeding. 26 Figure 8 demonstrates an example of an extensive intracardiac mass. In this patient, several biopsies were obtained guided by ICE.…”

A ccurate knowledge of the anatomy of intracardiac structures is essential for the efficiency and safety of performing interventional procedures. Although fluoroscopy is an important aid while advancing catheters in the heart, it is not sufficient to supply accurate anatomical information on the position of veins, ridges, and septa in the heart. Furthermore radiation exposure forms a risk to both the patient and the operator.Intracardiac echocardiography (ICE) is a promising technique for imaging of intracardiac structures, and may serve as an alternative for the transoesophageal approach, 1 which is semiinvasive and requires anaesthesiology. The introduction of ICE catheters with low frequencies allows accurate visualisation of intracardiac anatomical structures with an ultrasound catheter placed exclusively in the right side of the heart. This report focuses on the use of ICE in guiding percutaneous interventional procedures. BASICS OF INTRACARDIAC ECHOCARDIOGRAPHY cHistory of two dimensional intracardiac ultrasound systems The first application of ICE was done using mechanical ultrasound systems, which were introduced in the 1980s. These systems provided high resolution imaging, but because of the high frequency of the transducers (20-40 MHz), tissue penetration was only limited and anatomic intracardiac overviews could not be obtained. The subsequent development of lower frequency transducers allowed imaging of intracardiac structures, but these systems were still limited by the low steerability and over-the-wire design of the catheters. 2 The clinical use was improved by the development of flexible lower frequency transducers (9 MHz), but depth control of these catheters still was not sufficient to allow visualisation of the whole heart from the right side of the heart. In the 1990s, systems modified after transoesophageal echocardiographic probes were introduced. In these systems depth was improved by the use of lower frequencies (5 MHz). However, the large size of these transducers limited the clinical use. In recent years the development of steerable phased array ultrasound catheter systems with low frequency and Doppler qualities has expanded the clinical use of ICE.

“…Potential applications of ICE include guidance and monitoring during intracardiac interventions, perioperative monitoring, and diagnosis of pericardial, myocardial, and valvular disease. 16,[18][19][20] In the past we have developed a single-purpose method for determination of endo-and epicardial borders in ICE images and image sequences. 3 Figure 11 in Sec.…”

This paper provides examples of several medical image analysis applications for which single-purpose border detection approaches were developed in the past. However, the utility of these and other existing automated and semiautomated medical image analysis systems is limited by their narrow, frequently singlepurpose orientation. After a general approach to graph-based optimal border detection is overviewed, a new method for design of image segmentation systems is reported, in which the criterion of optimality is automatically determined by learning from border tracing examples. Border features employed in the designed method are selected from a predefined global set using radial-basis neural networks. The method was validated in intracardiac, intravascular, and ovarian ultrasound images. The achieved performance was comparable to that of our previously reported single-purpose border detection methods. Our approach facilitates development of general multi-purpose image segmentation systems that can be trained for different types of image segmentation applications. © 1999 SPIE and IS&T.
