Resynchronisation Therapy

Troubleshooting of left ventricular (LV) lead fractures in cardiac resynchronisation therapy patients is important, especially for those with limited and problematic transvenous LV lead placement. In this case, surgical epicardial LV lead implantation was employed.

New Biomarkers

Acute coronary syndrome (ACS) and its complications is one of the main reasons of mortality and invalidation in the world. New biomarkers, such as ST2, NT-proBNP и Pentraxin-3 (Ptx-3) present much more opportunities in the diagnostics of diseases and risk of its development.Aim.To investigate standards and “new” biomarkers in different variants of MI and cardiovascular events in 1 year after MI.Material and methods.In 180 patients with MI (61,4±1,7 years) we determined the serum concentration of standard and “new” (ST2, NT-proBNP, Ptx-3) biomarkers in groups with Q/non-Q, STEMI and NSTEMI and the endpoints (MI, strokes, repeated hospitalizations and sudden deaths) in 1 year (384,3±21,2 days) after MI.Results.Patients with Q-MI and STEMI had higher risk of unfavorable cardiovascular events (p<0,05). Ptx-3 >43,9 ng/ml was shown to be risk factor for sudden death (sensitivity 70,0%, specificity 52,9%), and >125,9±0,06 ng/ml (74,1% and 44,1%) — of recurrent MI.Conclusion.NT-proBNP, ST2 and Ptx-3 showed prognostic value in the diagnostics of unfavorable cardiovascular endpoints.

The Right

A 72-year-old man presented for routine dual chamber pacemaker interrogation 13 years following insertion for sick sinus syndrome. Increased noise, impedance and threshold of the right ventricular (RV) lead were identified. RV capture was maintained with an overall RV pacing burden of 47%. A routine generator replacement was scheduled alongside RV lead replacement. Fluoroscopy at the start of the procedure revealed an unexpected striking fracture of the RV pacing lead with complete separation of the proximal and distal portions within the RV. The patient was asymptomatic and described no predisposing factors. He underwent implantation of a new ventricular lead and generator and has remained well. This case demonstrates clear RV lead fracture as a late complication of pacemaker implantation despite maintained capture. This emphasises the need for a chest X-ray when a change in device parameters is noted at device interrogation even in the absence of symptoms.

Abstract Trauma-induced complete lead fracture is a rare complication of pacemaker implantation. Only a few cases have been previously reported. Common treatment included replacement of pacemaker and/or extraction of fractured lead. In this report, however, we describe this unique case of complete traumatic pacemaker lead fracture. The patient had her right-ventricular lead fractured after a bicycle accident and had lived with the fractured lead for 8 months prior to her hospitalization. After examinations, she was treated with a relatively conservative strategy. The pacemaker and fractured lead were left for further observation and follow-up.

The Relationship

Obstructive and central sleep apnea have been associated with increased risk of adverse cardiovascular events and mortality. Sympathetic dysregulation occurring as a result of the respiratory disturbance is thought to play a role in this increased risk. Sleep apnea increases the risk of arrhythmias, myocardial ischemia/infarction, stroke, and heart failure, all of which may increase mortality risk. A higher incidence of nocturnal arrhythmias, cardiac ischemia, and sudden death has been noted in subjects with sleep-disordered breathing (SDB). In this review, the association between SDB and each of these conditions is discussed, as well as the potential mechanisms underlying these risks and the effects of treatment of SDB. Particular emphasis is placed on the relationship between SDB and nocturnal atrial and ventricular arrhythmias, myocardial ischemia/infarction and sudden death.
