Abstract

Aims To characterize the diagnosis, frequency, and procedural implications of septal venous channel perforation during left bundle branch area pacing (LBBAP). Methods and results All consecutive patients undergoing LBBAP over an 8-month period were prospectively studied. During lead placement, obligatory septal contrast injection was performed twice, at initiation (implant entry zone) and at completion (fixation zone). An intuitive fluoroscopic schema using orthogonal views (left anterior oblique/right anterior oblique) and familiar landmarks is described. Using this, we resolved zonal distribution (I–VI) of lead position on the ventricular septum and its angulation (post-fixation angle θ). Subjects with and without septal venous channel perforation were compared. Sixty-one patients {male 57.3%, median age [interquartile range (IQR)] 69.5 [62.5–74.5] years} were enrolled. Septal venous channel perforation was observed in eight (13.1%) patients [male 28.5%, median age (IQR) 64 (50–75) years]. They had higher frequency of (i) right-sided implant (25% vs. 1.9%, P = 0.04), (ii) fixation in zone III at the mid-superior septum (75% vs. 28.3%, P = 0.04), (iii) steeper angle of fixation—median θ (IQR) [19 (10–30)° vs. 5 (4–19)°, P = 0.01], and (iv) longer median penetrated-lead length (IQR) [13 (10–14.8) vs. 10 (8.5–12.5) mm, P = 0.03]. Coronary sinus drainage of contrast was noted in five (62.5%) patients. Abnormal impedance drops during implantation (12.5% vs. 5.7%, P = NS) were not significantly different. Conclusion When evaluated systematically, septal venous channel perforation may be encountered commonly after LBBAP. The fiducial reference framework described using fluoroscopic imaging identified salient associated findings. This may be addressed with lead repositioning to a more inferior location and is not associated with adverse consequence acutely or in early follow-up. [ABSTRACT FROM AUTHOR]

7. Intermittent Loss of Capture: A Forgotten Phenomenon at Play.

Author

Ghosh, Anindya, Sriram, Chenni S., and Pandurangi, Ulhas M.

Subjects
HEART atrium, SYNCOPE, CHEST X rays, ELECTROCARDIOGRAPHY, VENTRICULAR tachycardia, IMPLANTABLE cardioverter-defibrillators, CARDIAC pacing, HEART block
Abstract

The article focuses on a case of intermittent atrial capture loss following a cardiac defibrillator implantation. Topics include the mechanisms behind the loss of atrial capture, such as electrotonic facilitation and partial depolarization of the atrial membrane and their relationship to pacing rates; the potential causes of altered membrane excitability, like lead-tissue trauma or ischemia; and the management of the patient through adjusting the lower rate limit (LRL) for consistent capture.

Abstract

The article focuses on complex pacemaker troubleshooting through a combined syntactic and semantic approach. Topics discussed include differentiating between selectively paced and intrinsic QRS morphology, violations of pacemaker timing cycles, and the importance of understanding pacemaker algorithms for problem-solving in cardiac pacing scenarios.

Abstract

Background: Cardiac electrophysiologic study and radiofrequency ablation (RFA) have become an established mode of treatment for patients with refractory arrhythmias. These procedures are carried out regularly at the cardiac catheterization laboratory of Madras Medical Mission India. Objective: The purpose of this study was to evaluate our experience with cardiac electrophysiologic studies (EPS) and RFA catheter of atrial fibrillation (AF). Materials and Methods: This was a retrospective study carried out in the Cardiac Electrophysiology Department of the Institute of Cardiovascular Diseases, Madras Medical Mission, India. All cases diagnosed to have AF following cardiac EPS between January 2010 and April 2014 was selected for the study. The records, which were obtained from the Cardiac Electrophysiology Clinical Research Office of Madras Medical Mission, were reviewed. Forty-nine cases were chosen for analysis, using SPSS statistical software version 15. Results: There were 49 patients, 23 males and 26 females. The mean age was 57.53 years. Commonly associated diseases were diabetes mellitus 8 (16.3%), hypertension 18 (36.7%), and coronary heart disease 14 (28.5%). The ventricular rate was rapid most cases (91.2%). AF was diagnosed as being paroxysmal in 40 (81.6%), persistent in 5 (10.2%), chronic in 3 (6.1%), and lone in 1 (2.0%). Ablation was carried out in 28 (57.1%), the success rate being 90% for pulmonary vein isolation, and 90.9% for atrioventricular node ablation. Complication rate was 2.04%. Conclusions: Treatment of AF by RFA is highly effective and safe. [ABSTRACT FROM AUTHOR]
