RESUMO

Minimally invasive cardiac surgery off-pump coronary artery bypass (MICSOPCAB) has become increasingly prevalent, with devices like the heart positioner aiding in surgical precision. However, rare complications such as epicardial hematoma can occur. Here, we present a case of a 75-year-old man undergoing MICSOPCAB who developed an epicardial hematoma due to the heart positioner. The hematoma was successfully repaired intraoperatively with direct suturing and large felts. Postoperative recovery was uneventful, highlighting the importance of vigilant monitoring and prompt management of such complications. This case underscores the need for careful attention during the use of cardiac positioners to minimize adverse events and ensure favorable patient outcomes.

RESUMO

Introduction: At our institution, we perform off-pump coronary artery bypass (OPCAB) as a standard procedure. Moreover, patients with favorable coronary anatomy and condition are selected for minimally invasive cardiac surgery (MICS)-OPCAB. We retrospectively compared early outcomes, focusing on safety, between MICS-OPCAB and conventional off-pump techniques for multivessel coronary artery bypass grafting (CABG). Methods: From August 2017 to September 2022, 1,220 patients underwent multivessel coronary artery grafting at our institution. They were divided into the MICS-OPCAB group (MICS group = 163 patients) and the conventional OPCAB group (MS group = 1057 patients). Propensity score matching (1 : 1 ratio) was applied to the MICS-OPCAB and MS groups (149 patients per group) based on 23 preoperative clinical characteristics. Results: After matching, there were no significant differences in preoperative characteristics between the groups. The MICS group had a lower total graft number (2.3 ± 0.6 vs. 2.9 ± 0.8, p < 0.001) and fewer distal anastomoses (2.7 ± 0.8 vs. 3.2 ± 0.9, p < 0.001). There were no significant differences in hospital stay, intensive care unit stay, postoperative complications, and 30-day mortality. The MICS group had less drain output (MICS 350 ml [250-500], MS 450 ml [300-550]; p = 0.013). Kaplan-Meier analysis revealed no significant differences in postoperative MACCE (major adverse cardiac or cerebrovascular events)-free and survival rates between the groups (MACCE-free rate p = 0.945, survival rate p = 0.374). Conclusion: With proper patient selection, MICS-OPCAB can provide good short to mid-term results, similar to those of conventional OPCAB.

RESUMO

Introduction: The procedure called the "aorta no-touch" (NT) or anaortic technique in off-pump coronary artery bypass grafting (OPCAB) is designed to reduce the perioperative risk of stroke. We have observed an increased frequency of anaortic OPCAB procedures at our institution. The main purpose of the present study is to investigate the effectiveness of anaortic OPCAB in reducing the perioperative risk of stroke. Methods: From April 2011 to July 2023, a total of 2,236 patients underwent isolated OPCAB at our single center. The patients were divided into the anaortic group (NT, n = 762) and the aortic group (A, n = 1,474). The NT group was propensity score-matched (PSM) with the A group at a 1:1 ratio (NT n = 640; A n = 640), and matching was performed based on 26 covariates with preoperative clinical characteristics. Results: In both the unmatched and matched cohorts of the NT and A groups, there were no significant differences observed in new stroke rates (NT vs. A; unmatched, 1.0% vs. 1.2%, p = 0.624; matched, 0.9% vs. 1.3%, p = 0.789). The univariable logistic analysis did not identify the anaortic technique as an independent factor negatively associated with new stroke events (OR = 0.81, 95% CI = 0.35-1.86, p = 0.624). Conclusion: The present study did not find the anaortic technique to reduce the perioperative risk of stroke in OPCAB. Hence, further large studies are needed to identify patient cohorts in which anaortic OPCAB is significantly beneficial.

RESUMO

Introduction: The minimally invasive cardiac surgery off-pump coronary artery bypass (MICSOPCAB) is technically difficult; therefore, previous studies have indicated that MICSOPCAB should be contraindicated in patients with impaired left ventricular (LV) function. In this study, we investigated the feasibility of MICSOPCAB in patients with impaired LV function. Methods: The 226 patients underwent MICSOPCAB between August 2017 and September 2022. Our study defined impaired LV function as ejection fraction (EF) in echocardiography 40% or less. The patients were divided into Low EF group (n = 39) and Normal EF group (n = 187). Results: The Low EF group was in a more critical preoperative condition than Normal EF group (41.0% in the Low EF group vs. 14.4% in the Normal EF group; p < 0.001). For preoperative transthoracic echocardiography, LV end-diastolic diameter (5.5 ± 0.9 cm in the Low EF group vs. 5.0 ± 0.8 cm in the Normal EF group; p < 0.001) and LV end-systolic diameter (4.4 ± 1.0 cm in the Low EF group vs. 3.4 ± 1.0 cm in the Normal EF group; p < 0.001) were significantly larger in the Low EF group. No differences were found in the operative time (180 [160-240] min in the Low EF group vs. 205 [165-253] min in the Normal EF group; p = 0.231) and the median number of distal anastomoses (2 [1-2] in the Low EF group vs. 2 [1-3] in the Normal EF group; p = 0.073). Intensive care unit stay was longer in the Low EF group than in the Normal EF group (2 [1-2] in the Low EF group vs. 1 [1-2] in the Normal EF group; p = 0.010). Perioperative transfusion was more common in the Low EF group than in the Normal EF group (69.7% vs. 49.2%; p = 0.023). There were no differences in major complications, hospital stay, and 30-day mortality. The Kaplan-Meier curve showed no significant difference in postoperative major adverse cardiac or cerebrovascular events rates between the two groups (p = 0.185). Conclusion: In this study, MICSOPCAB can be performed in patients with low EF having short- and mid-term outcomes similar to patients with normal EF. Therefore, low EF should not be contraindicated in MICSOPCAB.

RESUMO

Minimally invasive mitral valve surgery (MIMVS) is widespread and has become a standard procedure in cardiac surgery [Chitwood 1997; Carpentier 1996]. Therefore, MIMVS is a common procedure for patients with degenerative disease [Raanani 2010; Iribarne 2010] as well. However, the safety of MIMVS in patients with rheumatic heart disease (RHD) has not thoroughly been investigated, due to the low prevalence of RHD in developed countries, where MIMVS is standardized [Miceli 2015]. Here, we investigated the safety of MIMVS for patients with RHD at Lampang Hospital in Thailand.

RESUMO

Second-time coronary artery bypass grafting is sometimes technically challenging due to severe adhesion of the heart, difficulty of identifying target coronary arteries, advanced sclerosis of the ascending aorta and limited availability of graft vessels. Here we report a patient, in whom a coronary-to-coronary bypass grafting from the native right coronary artery to the left anterior descending artery using a free right internal mammary artery was used as a graft conduit.
