Cryoablation Versus Radiofrequency Ablation

2014-07-23 16:47:25 | BioPortfolio


The purpose of this retrospective study is to describe why and when we used cryo and why we crossed over when we used both RFA and cryo. It is also to determine if there is some predictor that would make us say one patient would be better served with one technique than another and to describe our overall acute success rate and then our 6-month recurrence rate with cryo ablation and compare it to our known success rate with RFA.


Cryotherapy (Cryo) is a new ablation energy source used instead of the radiofrequency (RFA) method for ablation of septal pathways. In the past year, we have used cryo approximately 50 times, however 50% of the cryo procedures crossed over from RFA to cryo or cryo to RFA. It appears to me that cryo use should be as an adjunct therapy to RFA instead of replacement of RFA.

I would like to describe why and when we used cryo and why we crossed over when we used both RFA and cryo. I would like to determine if there is some predictor that would make us say one patient would be better served with one technique than another. I would also describe our overall acute success rate and then our 6-month recurrence rate with cryo ablation and compare it to our known success rate with RFA. All of this can be done with a chart review.

This will be done through a retrospective study.

Medical and Biotech [MESH] Definitions

A heterogeneous group of disorders characterized by a congenital defect in neuromuscular transmission at the NEUROMUSCULAR JUNCTION. This includes presynaptic, synaptic, and postsynaptic disorders (that are not of autoimmune origin). The majority of these diseases are caused by mutations of various subunits of the nicotinic acetylcholine receptor (RECEPTORS, NICOTINIC) on the postsynaptic surface of the junction. (From Arch Neurol 1999 Feb;56(2):163-7)

Congenital disorders, usually autosomal recessive, characterized by severe generalized lack of ADIPOSE TISSUE, extreme INSULIN RESISTANCE, and HYPERTRIGLYCERIDEMIA.

A genetically heterogeneous group of heritable disorders resulting from defects in protein N-glycosylation.

Rare congenital metabolism disorders of the urea cycle. The disorders are due to mutations that result in complete (neonatal onset) or partial (childhood or adult onset) inactivity of an enzyme, involved in the urea cycle. Neonatal onset results in clinical features that include irritability, vomiting, lethargy, seizures, NEONATAL HYPOTONIA; RESPIRATORY ALKALOSIS; HYPERAMMONEMIA; coma, and death. Survivors of the neonatal onset and childhood/adult onset disorders share common risks for ENCEPHALOPATHIES, METABOLIC, INBORN; and RESPIRATORY ALKALOSIS due to HYPERAMMONEMIA.

A syndrome of congenital facial paralysis, frequently associated with abducens palsy and other congenital abnormalities including lingual palsy, clubfeet, brachial disorders, cognitive deficits, and pectoral muscle defects. Pathologic findings are variable and include brain stem nuclear aplasia, facial nerve aplasia, and facial muscle aplasia, consistent with a multifactorial etiology. (Adams et al., Principles of Neurology, 6th ed, p1020)
