Abstract
It has now been more than a quarter of a century since modulation of the sympathetic nervous
system was proposed for the treatment of cardiac arrhythmias of different origins. But it has
also been some time since some of the early surgical attempts have been abandoned. With the
development of ablation techniques, however, new approaches and targets have been recently
introduced that have revolutionized our way of thinking about sympathetic modulation. Renal
nerve ablation technology is now being successfully used for the treatment of resistant
hypertension, but the indication spectrum might broaden and new therapeutic options might
arise in the near future.
This review focuses on the possible impact of renal sympathetic system modulation on
cardiac arrhythmias, the current evidence supporting this approach, and the ongoing trials of
this method in electrophysiological laboratories. We will discuss the potential roles that
sympathetic modulation may play in the future.

Pathophysiology and past experience
Sympathetic activity plays an important role in the pathogenesis of ventricular
tachyarrhythmias (1) and the evidence for a major role of the sympathetic nervous system in
triggering cardiac events provided the rationale for antiadrenergic interventions such as left
cardiac sympathetic denervation (LCSD) (2,3). In the 1970s antiadrenergic interventions
were successfully used in patients with long-QT syndrome and later in patients suffering
from catecholaminergic polymorphic VTs. Those early strategies aiming at reducing
sympathetic activity had a potential to protect against ventricular arrhythmias by: I)
prevention/suppression of early afterdepolarizations and of reentrant mechanisms (4), II)
raising the ventricular fibrillation threshold (5), and III) shortening of the QT interval (2). As
of today, this surgical approach has been largely abandoned due to its high incidence of often
debilitating side effects such as orthostatic hypotension, palpitations, anhydrosis, intestinal
disturbances, loss of ejaculation, thoracic duct injuries, and atelectasis (6). However, the
concept of decreased sympathetic activity remained an important factor in the prevention and
treatment of ventricular arrhythmias as a target of multiple drugs including beta-blockers.
Despite recent data on RDN failing to perform better than in the placebo arm in resistant
hypertension (7), from a pathophysiological standpoint the antiarrhythmic effects of this
procedure may still be implied. Similarly to LCSD or percutaneus suppression of ganglion
stellatum, RDN results in a reduction of whole body norepinephrine spillover by 42% and
efferent muscle sympathetic nerve activity by 66% (8).

Asides from possible direct antiarrhythmic properties, RDN may ameliorate the symptoms of
chronic heart failure and therefore eliminate arrhythmias that are secondary to electrolyte
disturbances or cardiac decompensation.
Even though this hypothesis is based on contemporary pathophysiological considerations (9),
the effect of RDN on CHF has not yet been extensively studied. Nevertheless, the preliminary
results of a very recently published small series of studies are promising. Davies et al. (10)
performed RDN in 7 patients on maximal tolerated heart failure therapy with aggravated
symptoms of CHF. In this cohort, a subjective improvement of HF symptoms and increase of
6-minute walk distance at 6 months was observed. During the 2012 ESC session, similar
results were also reported by Taborsky et al. (11), who randomized 51 patients with
medically managed severe heart failure to either medical treatment (n = 25) or additional
RDN (N = 26) therapy. A significant improvement of ejection fraction, left ventricular end-
systolic volume index, left ventricular end-diastolic volume index, and NT-proBNP were
observed in the RDN treated group after 12 months follow-up. Furthermore, they reported a
relevant change in frequency of hospitalization and NYHA class in the RDN group.
Review of case series in patients with VT
In a short series published recently by Ukena et al. (12), RDN was tested in 2 patients with
primary non-obstructive hypertrophic and idiopathic dilated cardiomyopathy, who suffered
from therapy resistant electrical storm. Both patients were admitted with repetitive ventricular
arrhythmias including multiple monomorphic and also polymorphic VTs with rapid
degeneration into ventricular fibrillation. Previous attempts of interventional treatment via
endocardial or epicardial ablation were of limited efficacy or were declined by the patients.

In both cases, a combination of maximal beta-blockers dosage and other antiarrhythmic
drugs, including combinations of up to 3 agents, were ineffective. After exclusion of all
reversible causes, such as electrolyte disturbances, myocardial ischemia due to coronary
artery disease, QT-prolongation or cardiac decompensation and obtaining informed patient
consent, a bilateral RDN with six ablations at 8W for 2 minutes each was performed without
any apparent procedural complications. Even though both patients were relatively hypotonic
(mean blood pressure of 90/60 mmHg), the arterial pressure remained stable during the
procedure and most importantly during the following months. In the first few days after the
RDN procedure, both patients experienced recurrence of VT; but after this initial stabilization
phase, the antiarrhythmic effect of RDN was established as the VT burden dramatically
decreased and, as a consequence, the antiarrhythmic medication was reduced. Both patients
were discharged shortly after the procedure in good clinical condition and remain event-free
during the follow-up of up to 6 months.
Similar results have been recently published by Remo et al. (13). In 4 patients with different
etiologies (ischemic, hypertrophic and dilated cardiomyopathy) with mono- and polymorphic
VT, a bilateral RDN was performed. All patients had a history of previous cardiac ablations
and were treated with ≥ 2 antiarrhythmic drugs. Most interestingly, one of the patients had
undergone a bilateral cervical sympathectomy previously. In this difficult setting, RDN
proved to be a safe and effective tool for reduction and partial elimination of ventricular
arrhythmias. During the mid-term follow-up of 6 months, precluded by the short period of
recurrences, a significant decrease of VT burden was achieved.
Hoffmann at al. (14) reported similar adjuvant effect of RDN following VT ablation in a
acute setting of post-infarction fast VT/VF.
Those results are also reflected in our recent experience with a 23-year-old patient with

ischemic cardiomyopathy due to post-traumatic coronary artery dissection who was admitted
with recurrent VT. Despite two endo- and epicardial catheter ablations and maximum
tolerable dose of ß-blockers, the patient developed an electrical storm and received 33 ICD-
shocks within a month after the second ablation. Bundle branch reentrant VT episodes with a
pre-existing right bundle branch block and left posterior hemiblock morphology recurred
reproducibly on treadmill exercise testing even on a maximum dose of sotalol (360 mg per
day). Weighing the options (repeat catheter ablation with high risk of complete AV block vs
change in antiarrhythmic drug regimen vs RDN), bilateral RDN was preferred by the patient
and performed successfully (EnligHTN, St. Jude Medical). A 30-hour Holter ECG as well as
a treadmill exercise test 3 days after RDN showed no evidence of VT which allowed
reduction of antiarrhythmic drug dosage. Over the course of a 10-month follow-up period, no
VT events were recorded via remote monitoring of the ICD and the patient remained
asymptomatic.
Patient characteristics extracted from those series are presented in table 1.
Ongoing trials, future directions and open questions
All these cases provide encouraging preliminary data on the use of RDN for the treatment of
recurrent, refractory, and life-threatening arrhythmias. However, the role of RDN as an
adjunct or stand-alone therapeutic concept in patients with life-threatening arrhythmias and
heart failure is far from obvious and further evidence is needed. Recently a limited efficacy of
RDN in comparison to the shame procedure (7) in terms of blood pressure reduction was
reported. Although, those results might be partially caused by statistical trial design,
improved adhesion of control group during relatively a short follow-up period, increased

placebo effect, operator learning curve, and lacking intraprocedural endpoint must also be
taken under consideration when it comes to extending the indication for RDN.
The ongoing pioneer trials currently being conducted (Table 2) may be able to shed some
light on those questions.
Renal denervation for treatment of atrial fibrillation
Among all supraventricular arrhythmias, one has a special place due to extremely high
prevalence and strong association with morbidity and mortality (15): atrial fibrillation (AF).
Aside from several mechanisms such as atrial stretch and atrial remodeling (16-20), the
impairment of autonomic nervous system has been thought to contribute to the development
of AF substrates (21). In experimental animal models, the ß-adrenergic agonists (i.e.,
isoproterenol) in conjunction with rapid atrial pacing have been successfully used to induce
AF (22,23). Moreover, increased sympathetic activity is correlated with prolonged episodes
of AF and possibly a precondition for sustained AF (24). At the cellular level, it has been
observed that increased calcium levels along with subsequent shortening of the action
potential and refractoriness of` atrial myocardium may be related to sympathetic
overstimulation (25). Finally, recent series of animal studies have also shown that
sympathetic inhibition through RDN may suppress the development of AF induced by rapid
atrial pacing (26) and additionally, may inhibit atrial remodeling after prolonged AF (27).
Increased sympathetic activity and hypertension interacts also affect AF hemodynamically as
both acute and chronic blood pressure elevation can increase atrial stretching and dilation,
resulting in the promotion of arrhythmogenic substrate and/or induction of AF. Recently, it

has been shown in an animal model that the hypertensive group developed a progressive
increase in mean arterial pressure, longer mean effective atrial refractory periods, progressive
bi-atrial hypertrophy, atrial inflammation and left atrial dysfunction (28). All these
components are acknowledged risk factors for AF inducibility, which was also reported as
being significantly higher. Furthermore, the role of hypertension as a risk factor for the
development of AF in long- term follow-up has also been documented in large
epidemiological studies (29). This pathophysiological consideration, as well as experimental
and clinical observations, has been the background for the concept of RDN in the treatment
of AF.
The first attempts at evaluating RDN for AF treatment were designed to examine the adjunct
role of RDN in combination with catheter-based pulmonary vein isolation (PVI). The
breakthrough trial was recently reported as a randomized, prospective study by Pokushalov et
al. (30) describing the effect of RDN in patients with a history of refractory paroxysmal or
persistent atrial fibrillation (AF) who were on at least two antiarrhythmic drugs and had
resistant hypertension (systolic blood pressure 160 mm Hg despite triple drug therapy). In
the study, 27 patients were enrolled and randomized to either PVI only (n=14) or PVI and
RDN (n=13). During the scheduled 1-year follow-up visit, a significant reductions in systolic
(from 181 to 156 mm Hg, p < 0.001) and diastolic blood pressure (from 97 to 87mm Hg, p <
0.001) were observed in patients treated with PVI and RDN without significant change in the
PVI only group. The freedom from AF was also significantly improved in the experimental
group when compared with conventional PVI ablation only: 69% vs. 29% (p = 0.033).
Considering the relatively moderate success of radiofrequency ablation in the treatment of AF
in a long-term follow-up and the highly promising results of the additional RDN, this new
approach has a potential to become a clinically important therapeutic option for patients with

AF and hypertension.
Initial data in human studies testing the application of RDN as a stand-alone therapy are also
encouraging. Recently, a case report of persistent drug-resistant AF successfully being
treated with RDN instead of PVI was presented (31). Shortly after the procedure, a
spontaneous termination of persistent AF was observed and the AF recurrence did not appear
during the follow-up of 8 months. Furthermore, a left atrial size was also significantly
reduced from 45mm to 36mm at 6 months of follow-up.
Even though these data are definitively positive, they are still very weak to support the
potential antiarrhythmic role of RDN and its possible role in treatment of supra-ventricular
arrhythmias. However, more evidence is expected to come in the near future as a multitude of
clinical trials (Table 3) are ongoing.
