An Indian-origin researcher has developed novel epicardial ablation techniques that may help treat the heart from the outside, without breaking through the organ's tissue.
"The heart is surrounded by a one-millimeter wide, fluid-filled sac - that, by the way, you can't even see on X-ray," said Mahapatra, an assistant professor of internal medicine and biomedical engineering at U.Va.
The new tools allow doctors to go through that sac to the epicardium - the heart's outermost tissue - without actually entering the heart, "reducing patients' risk and recovery time," he added.
The researcher has revealed that among the the new tools is an "epi-needle access system", which includes a retractable needle and a sensor capable of measuring the pressure and pressure frequency of surrounding tissues.
He says that the revolutionary access system, developed with George T. Gillies, requires only one 3-millimeter incision, making it much less invasive than surgical methods.
"Any time you reduce the risks of a procedure, as we have done with the epi-needle, you make treatment available to more people. Because this technology is less invasive, we can use it to treat people who are currently not being treated," Mahapatra said.
According to him, good news is that conditions like heart failure, atrial fibrillation, ventricular tachycardia and oesophageal failure can be helped by the new epicardial technology.
Mahapatra further said that with its advanced precision, the epi-needle could also be used for safer pacemaker insertion, ablation techniques, stem cell delivery and drug delivery throughout the body, and it would reduce the risk of stroke associated with atrial fibrillation.
