Minimally Invasive Approach versus Sternotomy for Cardiac Surgery in Jehovah's Witness Patients

To evaluate the outcomes of minimally invasive cardiac surgery (MICS) compared with the sternotomy approach for Jehovah's Witness (JW) patients who cannot receive blood transfusions DESIGN: This was a retrospective observational study.

The study was conducted at a specialized cardiovascular intervention and surgery institute.

The study cohort comprised JW patients undergoing cardiac surgery between September 2016 and July 2022.

None MEASUREMENTS AND MAIN RESULTS: Patients (n = 63) were divided into MICS (n = 19) and sternotomy (n = 44) groups, and clinical outcomes were analyzed. There was no difference in types of operation except coronary bypass grafting (n = 1 [5.3%] in the MICS group v n = 20 [45.5%] in the sternotomy group; p = 0.005). There were no between-group differences in early mortality and morbidities. Overall survival did not differ significantly during the follow-up period (mean, 43.9 ± 24.4 months). The amount of chest tube drainage was significantly lower in the MICS group on the first postoperative day (mean, 224.0 ± 122.7 mL v 334.0 ± 187.0 mL in the sternotomy group; p = 0.022). The mean hemoglobin level was significantly higher in the MICS group on the day of operation (11.7 ± 1.3 mg/dL v 10.6 ± 2.0 mg/dL in the sternotomy group; p = 0.042) and the first postoperative day (12.3 ± 1.8 mg/dL v 11.2 ± 1.9 mg/dL; p = 0.032).

MICS for JW patients showed favorable early outcomes and mid-term survival compared to conventional sternotomy. MICS may be a viable option for JW patients who decline blood transfusions.
