“…Utilizing the CT and MP tissues of 10 adult dogs, it was proposed that the crista terminalis (CT) is known to initiate and maintain atrial arrhythmia and is affected by autonomic tone, but the underlying mechanisms were poorly understood [ 12 ]. Earlier workers have hypothesized that the development of atrial flutter can be attributed to the geometry of CT and the associated structures [ 13 ].…”

Background. The complex architecture of the right atrium, crista terminalis (CT), and the musculi pectinati (MP) poses enormous challenges in electrophysiology and cardiac conduction. Few studies have been undertaken to substantiate the gross features of MP, in relation to the CT, but there is still scarcity of data regarding this. We tried to reinvestigate the gross arrangement of muscle bundles in the right atrium. Methods. Utilizing 151 human hearts and orientation of MP and its variations and relationship to the CT were investigated along with taenia sagittalis (TS). Patterns of MP were grouped in 6 categories and TS under three groups. Result. A plethora of variations were observed. Analysis of all the specimen revealed that 68 samples (45%) were of type 1 category and 27 (18%) fell into type 2 category. Prominent muscular columns were reported in 12 samples (8%). 83 samples (55%) presented with a single trunk of TS. Multiple trunks of TS were reported in 38 samples (25%). Conclusion. Samples with type 6 MP and type B/type C TS, which have a more complex arrangement of fibers, have a tendency to be damaged during cardiac catheterization. Nonetheless, the area as a whole is extremely significant considering the pragmatic application during various cardiac interventions.

“…The transverse conduction block in the crista terminalis has been reported to be a major determinant in the arrhythmogenesis of CTI-dependent AFL. 26,27 Recent data with UHR showed that the crista terminalis was inconstantly observed during AFL, and that a more posterior line of the block may also be involved in 16 of 22 patients.…”

The precise circuit of cavotricuspid isthmus (CTI)-dependent atrial flutters (AFLs) has been well characterized, but the recent arrival of ultrahigh-resolution mapping systems has further improved our understanding of this "old" arrhythmia. CTI-dependent AFL may be the arrhythmia for which the electrocardiograph (ECG) correlation with the mechanism may be the highest. Once the diagnosis is made (predominantly based upon the surface ECG), the therapeutic options are precisely defined, with radiofrequency catheter ablation representing an efficient strategy with a high success rate and few complications. This article will focus on the clinical perspectives for CTI-dependent AFL.

“…The importance of SVC examination is illustrated in one of our patients with pericardial effusion (case 17) in whom the IVC could not be imaged subcostally because of recent liver transplantation but the right parasternal approach showed adequate SVC collapsibility and tamponade could be ruled out.3DTTE was also superior to 2DTTE in assessing the CT because a larger extent in a larger number of patients could be imaged by 3DTTE.This included 4 patients in whom the full extent of CT could be visualized by 3DTTE. Larger CT measurements with arborization in its lower part are more frequently noted in patients with atrial flutter 16. Also, a large majority of focal RA tachycardia in otherwise normal individuals arise along the CT 14.…”

Two‐ and three‐dimensional transthoracic echocardiographic assessment of superior vena cava, crista terminalis, and right atrial appendage using the right parasternal approach

Both SVC and RAA could be imaged by 2DTTE and 3DTTE in 53% of 40 patients (two separate groups of 20 consecutive patients) studied demonstrating the technical feasibility of this approach. SVC size and collapsibility, CT and RAA size, and RAA fractional shortening were evaluated in both groups by both 2D and 3DTTE. 3DTTE provided incremental value over 2DTTE by its ability to view en face the SVC in short axis and the base of RAA and RAA volumes resulting in more comprehensive assessment of their size and function.
