The implementation of new surgical techniques in an institution requires the suitable training of an interdisciplinary group (surgeons, anesthesiologists, nurses, doctors, ICU); the initial results, known as learning curve, are those that define the successful continuity of said techniques in the institutions, therefore they are of utmost importance.
Compare the pertaining patients to the learning curve group with the rest, both subjected to aortic valve replacement by the minimally invasive technique (MICS) conducted by the same group of cardiovascular surgeons, evaluating surgery time, postoperative complications, hospital stay and mortality.
83 consecutive cases were studied, with an age of 62.54 ± 12.60 years between 30 and 84 years, of them 70 (84.30%) were given an implanted Biological prosthesis and 13 (15.70%) a mechanical prosthesis, defined the learning curve as the first 25 procedures (Learning Curve) and compared with the 58 remaining procedures (The Rest).
Complication Learning Curve Rest
Reintervention due to bleeding
Hospital stay 6.72 ± 4.04 days Vs 7.16 ± 5.071 days p = 0.705 did not present statistically significant differences.
The learning curve in aortic valve replacement conducted by MICS can be initiated safely with a low morbimortality.
