Takayasu arteritis with recurrent coronary artery disease.

Takayasu arteritis is a rare type of large vessel vasculitis that commonly affects individuals of Asian descent. Coronary artery involvement is rare. We report the case of a young female with history of Takayasu arteritis who underwent stenting and reported with in-stent restenosis. She was managed with robot-assisted coronary artery bypass grafting using bilateral internal mammary arteries.

Total arterial revascularization using robot assisted minimally invasive coronary artery bypass: an Indian experience.

Objective: The aim of this study is to analyze the early outcomes of Total Arterial Revascularization using Robot Assisted Minimally Invasive Coronary Artery Bypass at our center between June 2019 and January 2023. Methods: This is a retrospective analysis of 195 patients who underwent Total Arterial Coronary Revascularization through Robot Assisted Minimally Invasive Coronary Artery Bypass procedure (RA-CABG) during the period of June 2019 and January 2023 in a quaternary care center in India. Primary outcome variables were in-hospital and 30-day mortality. Secondary outcome variables included duration of surgery, length of intensive care unit (ICU) stay, in-hospital stay and perioperative morbidity. The entire patient population was divided into two groups for a subgroup analysis based on when the surgery was conducted i.e. the years since the robotic program was begun at our institution with 81 patients in group I (2019-2021), and 114 patients in group II (2022-2023). Results: 195 patients [88.7% male, mean age of 61.34 ± 9.58 years] underwent RA-CABG during the 5-year period (2019-2023) by a single experienced surgeon and his team. Conversion to larger thoracic incisions was required in 5 cases (2.59%). In-hospital and 30-day mortality was 1.02% each. The average length of ICU stay and hospital stay were 2.82 ± 1.17 days and 5.84 ± 1.71 days respectively. The duration of ICU stay correlated with the number of internal mammary artery grafts procured (p = 0.0022). Median duration of follow-up was 11 months. Overall mortality was 3.62% and cardiac related mortality was 2.07%, and 5 patients (2.59%) underwent percutaneous coronary intervention. Results of the sub-group analysis revealed a statistically significant difference between the groups in terms of number of internal mammary artery grafts procured (p = 0.010), need for transfusions (p = 0.00031), ICU stay (p = 0.0005) and in-hospital stay (p = 0.0006). Conclusions: Total Arterial Coronary Revascularization through RA-CABG is a viable procedure in select patients. An experienced surgeon and team are required. Further studies in the form of randomized trials with long term follow-up are required to establish the overall utility, effectiveness and benefits to the patients.
