“…In contrast, Hummel et al 3 observed no difference in the diameter of the CS os between 28 patients with AVNRT and 22 control patients. DeLurgio et al 4 used intracardiac echocardiography to evaluate the CS in patients with AVNRT. They compared the anatomy of the proximal CS and the posteroseptal space in 11 patients with AVNRT to that in 9 patients with other mechanisms of tachycardia and found that CS anatomy did not differ between patients with and without AVNRT.…”

“…It has been observed in patients with AVNRT that the CS os is close to where a His‐bundle electrogram can be recorded and that CS cannulation from the femoral vein is easier than in patients with other forms of supraventricular tachycardia 1,2 . Although there have been prior fluoroscopic and intracardiac echocardiographic evaluations of the dimensions of the CS, the dimensions of the CS in patients with and without AVNRT still are controversial 3–5 . The aim of this study was to compare quantitatively the dimensions of the CS by two‐dimensional (2‐D) intracardiac echocardiography and to compare qualitatively the morphology of the CS by three‐dimensional (3‐D) intracardiac echocardiography.…”

“…With advance in technology, such as miniaturization of low frequency transducers capable of enhanced ultrasonic visualization of intracardiac structures, intracardiac echocardi-ography (ICE) has become not only a tool for clinical research, but also one for practical application. [1][2][3][4][5][6][7][8][9][10][11][12][13][14] Several ICE sections through the right atrium have been reported, but often their initial interpretation has been challenging. This is due to the fact that both ICE imaging planes necessary for the display of right atrial structures, as well as a method for image presentation, are not standardized.…”

A detailed understanding of the anatomic structures of both atria is mandatory for successful catheter-based interventional techniques. Some of the drawbacks of transthoracic and transesophageal echocardiography can be overcome by intracardiac echocardiography (ICE). We present our ICE experience based on 70 out of 186 patients who were included in a multicenter registry of transcatheter interatrial communication closures. The ultrasound catheter was a 9-Fr, 9 MHZ monoplane probe (Ultra ICE catheter) compatible with the motor drive unit and imaging console of the Clear View Ultra. Four slice selections in the axial plane and only one in the sagittal plane were needed in order to obtain a comprehensive guide to ICE interrogation. Their intracardiac ultrasound imaging presentation is an essential and nontrivial step. The anatomic coordinate system was maintained identical to a tomographic imaging plane as follows: Left/right and anterior/posterior in the axial planes and superior/inferior and anterior/posterior in the sagittal plane. In order to identify the imaging coordinates, two specific anatomic landmarks were used. The first one was the crista terminalis (at 10 o'clock) and the second one was the right atrial auricle (at 12 o'clock). Once the ultrasound images were orientated, their interpretation and spatial reconstruction were straightforward. In conclusion, a standardized ICE examination allows for a comprehensive evaluation of the right atrial anatomy and may be helpful in guiding therapeutic catheter-based interventions. The major clinical advantages of ICE include optimal contrast between soft-tissue structures, limited fluoroscopic exposure time, and good patient acceptance, thus avoiding general anesthesia.

“…They also stated that CS anomalies such as diverticula, persistent superior vena cava, and enlargement of the CS ostium were predominantly found in patients with accessory pathway‐related tachycardias. In contrast to previous researchers, Delurgio et al used intracardiac echocardiography (ICE) to assess the CS. They compared 11 patients with AVNRT and 9 patients without AVNRT, and found no difference in terms of the CSD.…”

BackgroundIn this study, we aimed to evaluate the coronary sinus (CS) morphology with three‐dimensional transthoracic echocardiography (3D‐TTE) in patients with supraventricular tachycardia (SVT) who underwent electrophysiological study (EPS).MethodsThis cross‐sectional study was conducted with 187 patients who underwent EPS between November 2016 and April 2017. Patients were divided into three groups: atrioventricular nodal reentrant tachycardia (AVNRT) (n = 72), non‐AVNRT SVT (n = 58), and normal EPS (n = 57). All patients were evaluated with electrocardiography, TTE, and 3D‐TTE.ResultsThe CS diameter (CSD) and area (CSA) were found significantly lower in the normal EPS group than in the other groups. There was no significant difference in the CSD between AVNRT and non‐AVNRT SVT groups. However, it was found that the CSA was significantly larger in the AVNRT group than in the non‐AVNRT SVT group. In linear regression analysis, age and left atrial diameter were determined as independent predictor for CSD and CSA (P < 0.001 for each one).ConclusionsThe CSD and CSA assessed by 3D‐TTE were different and dilated in the patients with SVT compared to those in the normal individuals. There was no significant difference in the CSD between the AVNRT and non‐AVNRT SVT groups. However, the AVNRT group had a larger CSA than the non‐AVNRT SVT group.
