Maquet Cardiovascular Presents Long-Term Data Of SMART Study

Maquet Cardiovascular has presented long-term results from the landmark SMART (Surgical Management of Arterial Revascularization) study at 46th annual meeting of the Society of Thoracic Surgeons.

The data provide confirmation of the efficacy of performing Coronary Artery Bypass Graft surgery (CABG) while the patient’s heart continues to beat a procedure known as Off-Pump Coronary Artery Bypass (OPCAB).

The SMART study was the first randomized US trial to compare OPCAB with conventional on-pump CABG surgery.

Long-term follow-up data collected from SMART study patients confirm that outcomes are similar based on an analysis of early and late graft patency, incidence of recurrent heart attack, need for re-intervention, and long-term survival between the two procedures at a mean of nearly eight years after surgery.

Data also confirms the durability of off-pump surgery complement conclusions from numerous previous studies showing that OPCAB offers post-operative patient benefits by reducing the risk of complications.

Puskas, chief of cardiac surgery at Emory Crawford Long Hospital, associate chief of cardiothoracic surgery at Emory University, and lead investigator of SMART study, said: “These long-term follow-up data provide additional evidence that the early benefits of OPCAB are not obtained at the expense of long-term survival or freedom from re-intervention.

“The SMART follow-up data add to the growing body of evidence supporting the long-term durability of OPCAB, including randomized studies performed in the UK and 10-year follow-up of CABG patients at our university.”
