Procedural duration and complications
The median length of the procedure was 360 min (IQR, 60 min), and we noticed no intraprocedural complications. Median duration of hospitalization measured seven days (IQR, 2 days). Following CA, six patients (24%) developed medical issues, five of which were mild (mild acute kidney injury, n=3; cystitis, n=1; pneumonia, n=1), and were managed with conservative measures. One patient (4%) developed severe acute kidney injury requiring dialysis, followed by partial recovery in renal function (serum creatinine levels at last follow-up, 1.6 mg/dl), with no need for permanent renal replacement therapy. Remarkably, there were no stroke/transient ischemic attacks, and no patient was hospitalized or had urgent visits for heart failure during follow-up.
