Outcomes After TMR Are Poor for Some Patients

Mobile Zone, Perfusion Zone

Diabetics and patients with a preoperative body mass index of less than 25 have worse 1-year outcomes after transmyocardial laser revascularization (TMR) compared with other patients, German researchers report.

Dr. Thomas Krabatsch and colleagues from the Deutsches Herzzentrum Berlin, performed a univariate analysis of 20 factors of 134 patients who underwent TMR, according to their report in the June issue of the Annals of Thoracic Surgery.

For diabetic patients, the odds ratio of benefiting from TMR was 0.43 compared with nondiabetic patients, the researchers found. In addition, patients with a body mass index of less than 25 had almost a threefold increased risk of death during the first postoperative year compared with patients with a body mass index of 25 or more (odds ratio 2.97), they add.

“In the future we will be more reluctant to use TMR in diabetic patients and those with a body mass index below 25,” Dr. Krabatsch and colleagues conclude. “Whether these patients are less likely to profit from the TMR procedure should be confirmed by studies based on larger populations.”

The Effect of Vacuum-Assisted Venous Drainage on Hemolysis During Cardiopulmonary Bypass

There was no significant increase in hemolysis among the groups, which demonstrates that the VAVD technique, even if lower negative pressure is preferred, can be applied safely and effectively to improve venous drainage and consequently, cardiac decompression, even if smaller venous cannulas are used, and also avoid from superfluous fluid addition to sustain adequate extracorporeal perfusion.
