“…The anterior leaflet of the MV is separated from the septum by the subaortic vestibule, having fibrous continuity with two of the leaflets of the aortic valve. The extremities of the fibrous continuity are the left and right fibrous trigones ( Figure 14 ), the right forming part of the central fibrous body [ 78 ]. The landmark for the site of the atrioventricular bundle of His is the central fibrous body that the crescentic hinge lines of the right and noncoronary leaflet of the aortic valve ( Figure 14 ).…”

The establishment of radiofrequency catheter ablation techniques as the mainstay in the treatment of tachycardia has renewed new interest in cardiac anatomy. The interventional arrhythmologist has drawn attention not only to the gross anatomic details of the heart but also to architectural and histological characteristics of various cardiac regions that are relevant to the development or recurrence of tachyarrhythmias and procedural related complications of catheter ablation. In this review, therefore, we discuss some anatomic landmarks commonly used in catheter ablations including the terminal crest, sinus node region, Koch's triangle, cavotricuspid isthmus, Eustachian ridge and valve, pulmonary venous orifices, venoatrial junctions, and ventricular outflow tracts. We also discuss the anatomical features of important structures in the vicinity of the atria and pulmonary veins, such as the esophagus and phrenic nerves. This paper provides basic anatomic information to improve understanding of the mapping and ablative procedures for cardiac interventional electrophysiologists.

“…One of the mechanisms is reentry associated with the false tendon. Another is believed to be triggered automaticity induced by mechanical stretching 4,6 . One of the possible mechanisms for the present VT is that the left lateral position changed the cardiac position, which may have stretched to the LV through the false tendon, thus leading to stretch induced VT.…”

“…These VTs can be successfully eliminated by radiofrequency ablation achieved at sites where an early Purkinje potential is recorded before the VT QRS complex [71]. In addition, it is postulated that the fascicular left ventricular tachycardia may originate from a false tendon or fibromuscular band that extends from the posteroinferior left ventricle to the basal septum and ablation at these sites can eliminate the VT [72][73][74]. However, this finding is not specific, and false tendons can occur in many patients without evidence of fascicular left ventricular tachycardia [75].…”

Ventricular tachycardia (VT) in patients without structural heart disease can be observed in 10% of patients presenting with ventricular arrhythmias. These VTs are characterized by QRS morphology, ventricular origin and their response to pharmacologic agents. It is essential to rule out structural heart disease in this population as this can significantly alter the management and the long-term prognosis. These VTs generally have a benign course and therapeutic options are aimed at relieving symptoms related to the arrhythmia. Medical therapy is effective in many patients and radiofrequency offers a cure to those who are refractory to medical therapy. Careful attention to the electrocardiogram can help localize the origin of the VTs, which is crucial when planning an ablation strategy.
