Hyderabad: Doctors at the city’s care hospitals used an Impella device, known as the world’s smallest heart pump, when recently performing a complex heart bypass on a high-risk patient.

Venkata Krishna, 70, from Tamil Nadu, was admitted to hospital with severe myocardial dysfunction with an EF of 23%, critical cardiac artery anatomy and multiple blocks where stent placement was not Not possible. The case presented the experts with a unique heart surgery case.

Head of the Department of CT Surgery, Dr. Rama Subramanyam, said: “The bypass was performed with a superior version of mechanical circulatory support called Impella. This revolutionary technique is very useful in heart bypass surgeries where the device is introduced through the skin via the lower extremity artery into the main chamber of the heart, i.e. the left ventricle (LV). Blood from LV is aspirated and delivered into the aorta which is the main artery that carries blood to the rest of the body, supplying blood to the required organs.

The use of the new Impella CP technique helped the postoperative course for three days, then was gradually weaned and explanted.

“It has made high-risk coronary bypass surgery relatively risk-free for the patient, doctors, nurses, and most importantly, family members,” Dr. Subramanyam added.
