I was born and raised in South Korea until I immigrated to the United States when I was 12 years old. I spent my childhood in San Diego and Chicago. I went to to Tulane University in New Orleans, LA for Bachelor of Science in neuroscience. I studied medicine at the University of Alabama at Birmingham and completed general surgery residency at the University of Kansas Medical Center in Kansas City, KS. Since completion of residency, I pursued cardiothoracic surgery fellowship at the University of Kansas Medical Center. My passion is in exploring newest topics in bread and butter general surgery, including minimally invasive robotic surgery options in coronary artery bypass grafting and valvular surgery.

Description
Objectives
Robotic mitral valve repair has been shown to be safe and equally efficacious when compared to open mitral valve repair. The potential benefits include small incisions and quicker recovery. While qualitive outcome of robotic mitral surgery has been widely published, the data on functional outcomes of robotic mitral valve repair is sparse. Our study aims to quantify the functional benefit of robotic mitral valve repair.
Methods
We performed a single institution, retrospective analysis of prospectively collected survey data to evaluate our objective. 203 patients who had undergone robotic mitral valvuloplasty between March 1, 2010 and September 31, 2020 were assessed. Among these patients, 63 patients responded to an online survey regarding postoperative functional outcomes using the modified KCCQ-12 survey. We performed a paired non-parametric Wilcoxon and one sample t-test to assess statistical significance in measured outcomes.
Results
We found that respondents had a statistically significant improvement in functional outcomes with respect to physical limitation (PL), symptom frequency (SF), quality of life (QL), social limitation (SL), and composite scores. The composite score difference using the one sample t-test was 17.16 out of 100 points, which was statistically significant. Similarly, paired non-parametric Wilcoxon test also showed statistical significance when comparing patient scores before and after the surgery.
Conclusions
There is limited data to support the functional improvement of patients who undergo robotic mitral valve repair. Our study found that patients who underwent robotic mitral valvuloplasty showed statistically significant improvement in heart failure symptoms as measured by modified KCCQ-12 survey.
