“…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.

“…This is thought to be the main pathology behind AFLUT rhythms. However, majority of the cases include structural and electrical abnormalities (similar to AFIB) as the main culprit behind the flutter waves [33–35]. One major difference in AFIB and AFLUT is that the thickness of the terminal crest of the atria and its capacity to block transverse conduction are increased in cases of AFLUT compared to AFIB [36,37].…”

The term ‘flutter’ and ‘fibrillation’ were first coined to differentiate the differences between fast, regular contractions in Atrial Flutter (AFLUT) with irregular, vermiform contractions of Atrial Fibrillation (AFIB). Management of these two diseases has been a challenge for physicians. Rate control (along with rhythm control) is the first line of management for symptomatic AFIB/AFLUT with Rapid Ventricular Rate (RVR). In some situations, atrial rhythms may not be well controlled by these anti-arrhythmic drugs, making cardioversion to sinus rhythm necessary. Anti-coagulation therapy in both the disease population is essential. Catheter ablation is an effective treatment option in certain patients that have AFIB/AFLUT refractory to medical management. Newer techniques like left atrial appendage (LAA) has been developed and is a highly attractive concept for the future in the management of AFIB/AFLUT. Newer novel drugs targeting specific ion channels are approaching the stages of clinical investigation. However, while advances in technologies have helped elucidate many aspects of these diseases, many mysteries still remain. This literature review serves as one of the guideline papers for current up-to-date management on both AFIB and AFLUT.

“…18 In this issue of PACE, Morita and colleagues bring a new piece to the puzzle. 19 As it appears that CT transverse conduction block is rate-and location-dependent, these authors used intracardiac echography to attempt to correlate various geometrical (architectural) parameters of the CT at various level along its course (every 5 mm), to its local transverse conduction properties. This was done at various pacing cycle length from both the anteroinferior right atrium (AIRA) and the proximal coronary sinus (PCS).…”
