HYDERABAD: In a unique procedure in India, the team of electrophysiologists at AIG Hospitals treated the irregular heartbeat of a high-risk patient who already had an artificial heart pump implant. The 34-year-old engineer had advanced heart failure and an implanted artificial heart pump known as a left ventricular assist device.
When he came to AIG Hospitals with an irregular heartbeat problem, he was diagnosed with ventricular tachycardia – a life-threatening arrhythmia involving extremely rapid heart rates. “Initially, multitudes of drugs were used with little effect, prompting attempts to deliver a therapeutic electric shock which again proved unsuccessful. Our concern was that if left untreated, this leads to a worsening of the right heart chambers and increases the risk for the patient,” the doctors said.
To solve this problem, AIG electrophysiology specialists, led by Dr. C Narasimhan, performed a complicated procedure that involved the introduction of multiple catheters through various blood vessels in the heart. Thanks to this, the electrical signals were analyzed to find precisely the problematic site at the origin of this rhythm problem.
“After finding the site, a 3D mapping system (Ensite Navx) was used to navigate and precisely locate the target. Finally, radiofrequency energy was used to terminate the arrhythmia – a procedure called VT ablation” , added Dr. Narasimhan.
