Central Aortic Cannulation for Total Coronary Revascularization via Anterior Thoracotomy: A Single-Center Initial...

We aimed to evaluate the feasibility, safety, and technical challenges of central aortic cannulation for total coronary revascularization via left anterior thoracotomy (TCRAT).

A retrospective, single-center observational study was conducted on the first 29 TCRAT cases performed with central aortic cannulation. The primary outcomes included operative mortality, stroke, conversion to sternotomy, major aortic bleeding, and dissection; the secondary outcomes included delirium, reoperation, infection, ICU stay, and hospitalization. The descriptive statistics were reported as means ± SD or median (interquartile range [IQR]).

The mean age of the patients was 57.2 ± 9.8 years, with 72% of these being male. The most frequent comorbidities observed in the study population were hypertension (62%), diabetes (52%), and peripheral artery disease (28%). The mean cross-clamp time was found to be 63 ± 27 min, and the mean CPB time was 118.6 ± 41.6 min. The occurrence of stroke, aortic dissection, major bleeding, and sternotomy conversions was not observed. One patient died from severe pneumonia on the ninth post-operative day. The mean ICU stay was 1.2 ± 0.4 days, and the mean hospital stay was 5.3 ± 1.1 days.

Central aortic cannulation appears to be a safe and feasible procedure for TCRAT, providing physiological antegrade flow and eliminating the complications associated with peripheral cannulation. The preliminary findings suggest that central arterial cannulation may be a safe and practical alternative for the TCRAT technique, but prospective comparative studies are required to confirm its benefits over the femoral and axillary approaches.
