The Effectiveness of the Combination of Visual Prompt-Fading and Direct Instruction Method in Teaching Pattern Building Skills to Students with Intellectual Disabilities
The aim of this study was to examine the effectiveness of the combination of visual prompt-fading and direct instruction method in teaching pattern building skills to students with intellectual disabilities. Three students at the age of six and seven diagnosed with intellectual disabilities and enrolled in a full-time inclusion program participated in the study, and multiple-probe design across subjects used to conduct the research. The dependent variable of the study was the participants' level of ability to build a pattern, and the independent variable was the combination of visual prompt-fading and direct instruction method. The data has been collected using tool sets and worksheets consisting of objects and object images. Graphical analysis technique has been utilized for data analysis. The findings of the study showed that a combination of visual prompt-fading and direct instruction method was effective in teaching pattern building skills to students with intellectual disabilities, but it was limited in terms of the generalization of these skills
Inadvertent right ventricular apical exit after stereotactic body radiotherapy for ventricular tachycardia: Every cloud has a silver lining
A 78-year-old man suffering from gastric cancer with ischemic cardiomyopathy
and recurrent ICD shocks consented to ventricular tachycardia (VT) ablation. He
had a previous endocardial VT ablation 1 year ago, and a stereotactic radioablation for his recurrent VT 4 months ago. We planned again left ventricular endocardial mapping for his incessant slow VT suggesting an apical exit site (Figure 1A).
However, the activation mapping of LV did not cover the whole VT cycle length, and we decide to map the right ventricular septal side
instead of the epicardial access due to the patient's poor
frailty. Fortunately, the mid-diastolic potential (MDP) was
acquired in an unusual position (Figures 1A and 1B); however,
the pericardial location of the mapping catheter was confirmed fluoroscopically (Figures 1C and 1D). An urgent surgical consultation was called for, and operative preparations
were initiated. However, since no pericardial tamponade
occurred and blood pressure remained stable, we continued
the endo-epicardial ablation by ablating the MDP (Video 1)
Transient changes in QRS morphology during a narrow complex tachycardia: What is the mechanism?
A22‐year‐old man with recurrent episodes of tachycardia inthe absence of structural heart disease underwent an electro-physiological evaluation. A narrow complex tachycardia (NCT)was induced by programmed by ventricular pacing. A transientchange in QRS morphology and H‐V interval in the middle of thetracing was noted during ongoing tachycardia (Figure1).

Reply to letter to the editor: '2D LGE or 3D high-resolution LGE: Role of cardiovascular magnetic resonance imaging in the treatment of ventricular arrhythmias'
We are pleased that our paper raised interest among readers of the Anatolian Journal of Cardiology. Even though the late gadolinium enhancement cardiac magnetic resonance (LGE-CMR) imaging was first established for ventricular tissue characterization in localizing ventricular tachycardia (VT) ablation targets (CMR-aided), it is by now widely used as a clinical tool to guide VT ablation (CMR-guided) through the detection of the arrhythmogenic substrate and conducting channels. While the CMR-derived information has been used alongside electroanatomic mapping (EAM) data to aid VT ablation (CMR-aided), the CMR-guided approaches, where EAM acquisition is completely avoided, make procedures faster, and the operator relies solely on imaging data.1 As the authors reported, the analysis of CMR images with software, which is known as ADAS (ADAS 3D, Barcelona, Spain), is very helpful for identifying these conducting channels.2 The preliminary results showed that the mean procedure duration was lower in CMR-guided when compared to CMR-aided and No-CMR substrate ablation (109 ± 61 vs. 206 ± 70 and 233 ± 48 minutes, respectively; P <.001 for both comparisons).1 VOYAGE is a prospective, randomized, multicenter controlled open-label study designed to compare in terms of efficacy, efficiency, and safety of a CMR-aided or guided workflow to standard EAM-guided VT ablation
Cardiac magnetic resonance-guided conducting channel delineation of an aneurysmal ventricular tachycardia with the same circuit in the reverse direction
A 54-year-old male patient with remote inferior wall myocardial infarction with inferoseptal left ventricular (LV) aneurysm (Figure 1A, Video 1) was referred for ablation of hemodynamically tolerated ventricular tachycardia (VT). Image processing (ADAS 3D Galgo Medical, Barcelona, Spain) was used to reconstruct myocardial scar from cardiac magnetic resonance (CMR) and to identify channels of heterogeneous tissue that could be directly involved in the VT reentry circuit (Figure 1B, Videos 2-4). Then, this 3-dimensional (3D) CMR analysis was uploaded into 3D electroanatomic mapping system (CARTO® Biosense Webster Inc., Diamond Bar, CA, USA)
The width of life is more important than the length of life
A 58-year-old man with previous inferior myocardial infarction (MI) was referred for cardiac resynchronization therapy pacemaker (CRT-P) for decreased left ventricular ejection fraction (LVEF; 45%) and left bundle branch block (LBBB) (Figure 1). He had New York Heart Association Class I functional classification but palpitation for 3 months. General physical and cardiac examinations were normal. On the admission day, the electrocardiogram showed a narrow QRS rhythm with and without tachycardia (Figures 2 and 3). Would you recommend or consider a CRT-P device or a CRT defibrillator or only an implantable cardioverter defibrillator (ICD) based on these clinical and electrocardiographic findings, or ablation or medical therapy only
Change in atrial activation patterns during narrow complex tachycardia: What is the mechanism?
A change in the coronary sinus (CS) activation pattern from an eccentric to a concentric pattern during the ablation of an orthodromic reciprocating tachycardia might falsely suggest the presence of a second (septal) accessory pathway (AP) during tachycardia or the successful ablation of the left lateral AP under ventricular pacing despite persistent and unaffected AP conduction. Complete or partial intra-atrial block should be suspected when an abrupt change in the atrial activation sequence is noted during catheter ablation at the posterolateral and lateral aspects of the mitral annulus. The correct anatomical position of the CS catheter plays a vital role in the differential diagnosis of this situation
Convergent double coronary sinus potentials during atrial tachycardia
The analysis of the patterns and timing of coronary sinus activation provides a rapid stratification of the most likely macro-re-entrant atrial tachycardias and points toward the likely origin of centrifugal ones by comparing the left atrial and coronary sinus activation sequence and morphology during sinus rhythm and atrial tachycardia. The analysis of both the near- and far-field electrogram morphology of atrial signals also gives important clues in determining the mechanism of the arrhythmia
The roles of pre–P-wave versus peri–P-wave fractionated electrograms for atrial substrate beyond entrainment response
Atrial tachycardia (AT) with alternating cycle lengths is sparsely reported, and, hence, the ideal mapping strategy has not been firmly established. Beyond the entrainment during tachycardia, some fragmentation characteristics might also give important clues for its possible participation in the macro–re-entrant circuit. We discuss a patient with prior atrial septal defect surgical closures who presented with dual macro–re-entrant ATs related to a fragmented area on the right atrial free wall (240 ms) and the cavotricuspid isthmus (260 ms), respectively. After ablation of the fastest AT on the lateral right atrial free wall, the cycle of the first AT changed to the second AT that was interrupted on cavotricuspid isthmus, proving the dual tachycardia mechanism. This case report addresses the utilization of electroanatomic mapping information as well as fractionated electrogram timing with respect to the surface P-wave as guides for ablation location
