RESUMEN
OBJECTIVE: While the benefits of minimally invasive aortic valve surgery compared with standard sternotomy have been widely described, the impact of preservation of pleural integrity (PPI) in minimally invasive surgery is still widely discussed. This study aims to define the role of PPI on postoperative and long-term outcomes after minimally invasive aortic valve replacement (MIAVR). METHODS: All 2,430 consecutive patients undergoing MIAVR (ministernotomy or right anterior minithoracotomy) between 1997 and 2022 were included in the study. Patients were divided into 2 groups: patients with and without PPI. PPI was considered the maintenance of the pleura closed without the need for a chest tube insertion at the end of the surgical procedure. A propensity-matched analysis was used to compare the PPI and not-PPI groups. RESULTS: After propensity matching, 848 patients were included in each group (PPI and not-PPI). The mean age was 70.21 versus 71.42 years, and the mean Society of Thoracic Surgeons predicted risk of mortality was 0.31% versus 0.30% in not-PPI versus PPI, respectively. The mean follow-up time was 147.4 months. Postoperatively, not-PPI versus PPI patients had a longer intensive care unit stay (9.7 vs 17.3 h, P < 0.001) and hospital length of stay (5.2 vs 8.9 days, P < 0.001). The rate of respiratory complications including the incidence of pneumothorax or subcutaneous emphysema, pulmonary atelectasis, and pleural effusion events requiring thoracentesis/drainage was significantly higher in not-PPI versus PPI. The 30-day all-cause mortality was higher in not-PPI versus PPI (0.029 vs 0.010, P = 0.003). Perioperative, short-term, and long-term all-cause mortality was significantly higher in the not-PPI group. CONCLUSIONS: PPI after MIAVR is associated with reduced incidence of postoperative complications, reduced lengths of stay, and improved overall survival compared with not-PPI. Therefore, a MIAVR tailored patient-procedure approach to maintaining the pleura integrity positively impacts short-term and long-term outcomes.
RESUMEN
To develop risk scoring models predicting long-term survival and major adverse cardiovascular and cerebrovascular events (MACCEs), including myocardial infarction and stroke after coronary artery bypass grafting (CABG). All 4,821 consecutive patients who underwent isolated CABG at Lankenau between January 2005 and July 2021 were included. MACCE was defined as all-cause mortality + myocardial infarction + stroke. Variable selection for both outcomes was obtained using a double-selection logit least absolute shrinkage and selection operator with adaptive selection. Model performance was internally evaluated by calibration and accuracy using bootstrap cross-validation. Mortality and MACCEs were compared in patients split into 3 groups based on the predicted risk scores for all-cause mortality and MACCEs. An external validation of our database was performed with 665 patients from the University of Brescia, Italy. Preoperative risk predictors were found to be predictors for all-cause mortality and MACCEs. In addition, being of African-American ethnicity is a significant predictor for MACCEs after isolated CABG. The areas under the curve (AUCs), which measures the discrimination of the models, were 80.4%, 79.1%, 81.3%, and 79.2% for mortality at 1, 2, 3, and 5 years follow-up. The AUCs for MACCEs were 75%, 72.5%, 73.8%, and 72.7% at 1, 2, 3, and 5 years follow-up. For external validation, the AUCs for all-cause mortality and MACCEs at 1, 2, 3, and 5 years were 73.7%, 70.8%, 68.7%, and 72.2% and 72.3%, 68.2%, 65.6%, and 69.6%, respectively. The Advanced (AD) Coronary Risk Score for All-Cause Mortality and MACCE provide good discrimination of long-term mortality and MACCEs after isolated CABG. External validation observed a more AUCs greater than 70%.

OBJECTIVE: This study sought to identify periprocedural risk predictors that affect long-term prognosis in patients with chronic obstructive pulmonary disease (COPD) undergoing isolated coronary artery bypass grafting (CABG). METHODS: All consecutive 4,871 patients undergoing isolated CABG between May 2005 and June 2021 were included. Patients with and without COPD were compared for baseline demographics and preoperative characteristics. A propensity-matched analysis was used to compare the 2 groups. The primary outcome was long-term incidence of all-cause death. RESULTS: After matching, 767 patients each were included in the COPD and non-COPD groups; mean age was 71.6 and 71.4 years (P = .7), respectively; 29.3% and 32% (P = .2) were women, respectively. Intraoperatively, median (IQR) operating room time was higher in the COPD group than in the non-COPD group (5.9 [5.2-7.0] hours vs 5.8 [5.1-6.7] hours, respectively; P = .01). Postoperatively, intensive care unit stay (P = .03), hospital length of stay (P = .0004), and fresh frozen plasma transfusion units (P = .012) were higher in the COPD group than in the non-COPD group. Thirty-day mortality was not different between groups (1.3% in the COPD group vs 1% in the non-COPD group; P = .4). Median follow-up time was 4.0 years. The rate of all-cause death was higher in the COPD group than in the non-COPD group (138 patients [18.3%] vs 109 patients [14.5%], respectively; P = .042). Periprocedural risk predictors for all-cause death in patients with COPD were atrial fibrillation, diabetes, male sex, dialysis, ejection fraction less than 50%, peripheral vascular disease, and Society of Thoracic Surgeons Predicted Risk of Mortality score greater than 4%. CONCLUSION: Patients with COPD undergoing isolated CABG had a significantly higher incidence of all-cause death than those without COPD. Herein, risk predictors are provided for all-cause death in patients undergoing isolated CABG.

Outcomes of robotic-assisted reverse hybrid coronary revascularization (HCR) remain hindered. We aimed to analyze midterm clinical outcomes of robotic-assisted reverse HCR. All consecutive 285 patients who underwent reverse robotic-assisted HCR between September 2005 and July 2021 were included. Reverse HCR comprises percutaneous coronary intervention with stent implantation in non-left anterior descending (LAD) coronary arteries was performed within 30 days before robotic-assisted left internal thoracic artery (LITA) harvesting and LITA-to-LAD manual anastomosis through a 4-cm left minithoracotomy. Dual antiplatelet therapy was not interrupted in any patient. Preoperatively, mean age was 70.2 years (±11.2). Before surgery, 168 patients received 1 stent, 112 patients 2 stents, and 5 patients 3 stents. Intraoperatively, mean operating room time was 5.9 hours (±1); no case was converted to full sternotomy, whereas 9 patients (3.1%) received intraoperative blood product transfusions. Postoperatively, a small incidence of stroke, 1 (0.3%), reoperation for bleeding, 7 (2.4%), blood product transfusions, 48 (16.8%), and hospital stay (4.8 days) was observed. At 30-day follow-up, 1 patient (0.3%) underwent percutaneous coronary intervention with stent on a surgical LITA-LAD anastomosis owing to graft failure. Mean follow-up was 4.2 years. Reported midterm outcomes included all-cause death in 31 patients (10.9%), major adverse cardiovascular and cerebrovascular events in 102 of 285 (35.9%), nonfatal stroke in 2 of 285 (0.7%), myocardial infarction in 17 of 285 (5.9%), and repeat intervention in 50 of 285 patients (17.5%). This single-center study reports effective and safe clinical outcomes at midterm follow-up of reverse HCR procedures for treating multivessel coronary artery disease.

Aim: To evaluate clinical outcomes after redo aortic valve replacement (AVR) with sutured valves, versus valve-in-valve transcatheter aortic valve replacement (ViV-TAVR), versus sutureless valves. Methods: We identified 113 consecutive patients undergoing redo AVR with either ViV-TAVR, redo-sutured and redo-sutureless valves between August 2010 to March 2020. Heart-team made the decision whether patient should undergo redo-sutureless versus ViV-TAVR, versus redo-sutured AVR. Results: Preoperatively, redo-sutured (n = 57), ViV-TAVR (n = 31) and redo-sutureless (n = 25) patients were compared. Postoperatively, after propensity-adjustment analysis, the redo surgical aortic valve replacement group had a higher incidence of new postoperative atrial fibrillation (POAF; p = 0.04) compared with redo-sutureless group. Follow-up outcomes analysis did not show differences among groups. Conclusion: Patients undergoing redo-sutureless AVR experienced a higher incidence of POAF compared with patients undergoing redo-sutured.

The radial artery has been used for decades as an alternative to other arterial bypass graft conduits. Positive long-term patency results and survival benefits have led to an increase in its popularity. The emerging evidence of the need for total arterial myocardial revascularization unleashes the potential of the radial artery as a versatile arterial conduit capable of reaching all coronary targets in a lot of different configurations. In addition, a radial artery graft has proven benefits in terms of graft patency compared with a saphenous venous graft. In this context, multiple randomized clinical trials have repeatedly proven the improved clinical outcomes of radial artery grafts based on 10 years of follow-up; the radial artery graft has also been shown to be a suitable arterial conduit in up to 90% of coronary artery bypass grafting cases. Despite the scientific evidence regarding the benefits of the radial artery graft, most surgeons are still reluctant to use the radial artery in coronary artery bypass graft procedures. Consequently, surgical residents risk not developing solid surgical skills for utilization of the radial artery graft. Safe, easy-to-learn techniques are needed to speed up the learning curve and at the same time lower the complications. In this context, a fully no-touch technique for harvesting the radial artery using a harmonic scalpel can be the right way to introduce young surgeons to this basic but paramount skill.

Objective: The goal of this manuscript is to compare clinical and echocardiographic outcomes of patients undergoing aortic valve replacement (AVR) with Perceval sutureless bioprosthesis (SU-AVR) and sutured bioprosthesis (SB). Methods: Following the PRISMA statement, data were extracted from studies published after August 2022 and found in PubMed/MEDLINE, EMBASE, CENTRAL/CCTR, ClinicalTrials.gov, SciELO, LILACS, and Google Scholar. The primary outcome of interest was post-procedural permanent pacemaker implantation, and the secondary outcomes were new left bundle branch block (LBBB), moderate/severe paravalvular leak (PVL), valve dislocation (pop-out), need for a second transcatheter heart valve, 30-day mortality, stroke, and echocardiographic outcomes. Results: Twenty-one studies were included in the analysis. When SU-AVR was compared to other SB, mortality ranged from 0 to 6.4% for Perceval and 0 to 5.9% for SB. Incidence of PVL (Perceval 1-19.4% vs. SB 0-1%), PPI (Perceval 2-10.7% vs. SB 1.8-8.5%), and MI (Perceval 0-7.8% vs. SB 0-4.3%) were comparable. In addition, the stroke rate was lower in the SU-AVR group when compared to SB (Perceval 0-3.7% vs. SB 1.8-7.3%). In patients with a bicuspid aortic valve, the mortality rate was 0-4% and PVL incidence was 0-2.3%. Long-term survival ranged between 96.7 and 98.6%. Valve cost analysis was lower for the Perceval valve and higher for sutured bioprosthesis. Conclusions: Compared to SB valves, Perceval bioprosthesis has proved to be a reliable prosthesis for surgical aortic valve replacement due to its non-inferior hemodynamics, implantation speed, reduced cardiopulmonary bypass time, reduced aortic cross-clamp time, and shorter length of stay.
RESUMEN
BACKGROUND: The aim of this study is to identify risk predictors that impact long-term prognosis in patients undergoing isolated aortic valve replacement (AVR) with Perceval sutureless bioprosthesis aortic valve implantation. METHODS: From 2013 to 2020, 101 consecutive participants who underwent isolated AVR with the Perceval sutureless bioprosthesis were included. Primary endpoint was analysis of all-cause mortality. We performed a propensity-adjusted analysis of patients undergoing redo sutureless vs redo sutured AVR to understand the impact of sutureless valves in redo operations. RESULTS: Pre-operative characteristics included a mean age of 71.2-years, mean EuroScore II of 3.51 (±4.48), mean body mass index of 30.2 (±6.8). Mean follow-up was 1.5 years. Intraoperatively, mean cardiopulmonary bypass time and aortic cross-clamp time were 65 ± 29.6 and 47.3 ± 21.3 min, respectively. Valve redeployment was necessary in 9.9 % of cases and there was one intraoperative death. There were two hospital deaths (including the operative death) while only one was cardiac related. Postoperatively, mean ejection fraction was 55.5 % (±4.1 %), mean effective orifice was 1.5 (±0.3) cm2, and mean transvalvular gradient was 14.7 (±4) mmHg. At 7-years follow-up, 87.9 % of patients were alive. Risk predictors for all-cause death were female sex and left ventricular diastolic dysfunction (LVDD) grade ≥ 2. After matching, aortic cross-clamp time, inotrope use, blood product transfusions, respiratory failure, and post-operative arrhythmias were higher in the redo sutured group compared to the sutureless redo group. CONCLUSIONS: Sutureless aortic valve implantations have good clinical outcomes. Risk predictors for all-cause death included female sex and LVDD grade ≥ 2.

OBJECTIVES: Ministernotomy and right anterior minithoracotomy are the 2 main techniques applied for minimally invasive aortic valve replacement. The goal of this study is to compare early and long-term outcomes of both techniques. METHODS: The data of 2419 patients undergoing isolated minimally invasive aortic valve replacement between 1999 and 2019 were prospectively collected. Retrospectively, patients were divided into the ministernotomy group (n = 1352) and the minithoracotomy group (n = 1067). RESULTS: After propensity score matching, 986 patients remained in each group. Operation time and rate of conversion to full sternotomy were significantly higher in the minithoracotomy group than in the ministernotomy group (184.6 ± 45.2 vs 241.3 ± 68.6, relative risk, 2.54, P = .005 and .09 vs .23, relative risk, 1.45, P = .013, respectively). The 30-day mortality, excluding cardiac death, was lower in the ministernotomy group than in the minithoracotomy group (0.012 vs 0.028, relative risk, 1.41, P = .011, respectively); the intensive care unit length of stay (12.4 vs 16.5, relative risk, 1.62, P = .037, respectively) and hospital length of stay (5.4 vs 8.7, relative risk, 1.74 P = .028, respectively) were significantly longer in the minithoracotomy group. The minithoracotomy surgical approach was the strongest independent predictor of early mortality (odds ratio, 4.24 [1.67-7.35], P = .002). The actuarial survival by Kaplan-Meier analysis at 1, 3, 5, 10, and 20 years was significantly better in the ministernotomy group than in the minithoracotomy group (P = .0001). Actuarial freedom from reoperation at 5 years was 97.3% ± 4.4% in the ministernotomy group versus 95.8% ± 5.2% in the minithoracotomy group (P = .087). CONCLUSIONS: Minimally invasive aortic valve replacement using ministernotomy is associated with reduced operative time, intensive care unit stay, hospital length of stay, and postoperative morbidities and incisional pain, and improves early and long-term mortality.

Background: To investigate the impact of Cryo Nerve Block with cryoICE™ device utilization, on post-operative pain in patients undergoing isolated coronary artery bypass grafting (CABG) through left thoracotomy. Methods: All consecutive patients undergoing isolated CABG through left thoracotomy between July 2021 and July 2022 from a single surgeon were included in the study. Patients using the cryoICE™ device for nerve block were compared for baseline demographics and pre-operative characteristics with those that did not use the cryoICE™ device. A propensity-adjusted analysis was used to compare the two groups. The primary outcome was degree of incisional pain and numbness. Results: A total of 103 patients underwent isolated CABG through left thoracotomy. After matching, the cryoICE™ device was used for nerve block in 60 patients while the control group included 43 patients. Mean follow-up was 5.7 months. The cryoICE™ device group had a mean value of incisional pain at hospital discharge was 1.5 (scale 0-10) while at follow-up was 0.69 (scale 0-10). Mean values of skin numbness at hospital discharge were 1 (scale 0-10) and 0.57 (scale 0-10) at follow-up. After univariate analysis comparison of cryoICE™ device group (60 patients) versus non-cryoICE™ device group (43 patients), the total in-hospital morphine use was 49% lower in the cryoICE™ versus the non-cryoICE™ cohort (73.8 + 79.37 mg vs 144.1 + 118.99 mg). Conclusions: Good clinical outcomes were observed in patients undergoing isolated left thoracotomy CABG with cryoICE™ utilization, including a very low incidence of post-operative pain, numbness, and hypersensitivity for all comers.
RESUMEN
BACKGROUND: Vasoplegic shock syndrome (VSS) after an off-pump coronary artery bypass graft (OPCABG) is an extremely rare condition. Inotropic support is usually the first-line therapy, though it can precipitate several complications or be ineffective. We report the first case of severe refractory VSS after OPCABG successfully treated with hydroxycobalamin. METHODS: A 77-year-old gentleman underwent OPCABG for three vessels coronary artery disease. Preoperative LV ejection fraction was 28%, and the patient before surgery started sacubitril/valsartan titrated, then, at the highest dose. Surgery was uneventful and, by the end of the procedure, TEE showed improved biventricular contractility. RESULTS: The patient was transferred to the ICU without inotropic support, but soon developed hypotension. TEE ruled out pericardial tamponade and confirmed fair contractility. Norepinephrine was titrated to a medium-high dose, vasopressin was started and a Swan-Ganz catheter was placed. SVR was 480 dyn·s·cm-5. Despite aggressive pharmacologic treatment (including methylprednisolone and methylene blue), no improvements were noticed. Ten grams of hydroxycobalamin were administered. One hour later, hemodynamic status re-assessment showed SVR > 800 dyn·s·cm-5. Afterward, vasopressors were gradually reduced. CONCLUSIONS: Our case demonstrated the importance of adequate early treatment in VSS after OPCABG. This case report shows, for the first time, that hydroxycobalamin was effectively used to restore homeostasis.
RESUMEN
OBJECTIVES: To highlight short- and long-term clinical outcomes of the Intuity TM rapid deployment prosthesis for surgical aortic valve replacement. METHODS: We reviewed on PubMed/MEDLINE, Embase, SciELO, LILACS, CCTR/CENTRAL, and Google Scholar for clinical trials, retrospective clinical studies, meta-analysis, and gray literature. RESULTS: Fourty-five clinical studies with 12.714 patients were included in the analysis. Thirty-day mortality ranged from 3.8% for Intuity and 3.9% for transcatheter aortic valve replacement (TAVR). The incidence of paravalvular leak (PVL) (Intuity 0% and TAVR 2.17%), permanent pacemaker implantation (Intuity 11.11% and TAVR 12.5%), stroke (Intuity 2.2% and TAVR 2.6%), myocardial infarction (MI) (Intuity 0% and TAVR 1%), were all higher in the TAVR group. Compared to other sutured bioprosthesis (SB), mortality ranged from 0% to 3.9% for Intuity and 0%-6.9% for SB. Long-term cardiac mortality ranged from 0.9% to 1.55% for Intuity and 1.4%-3.3% for the Perceval valve. The incidence of PVL (Intuity 0.24%-0.7% and Perceval 0%-1%), endocarditis (Intuity 0.2%-0.7% and Perceval 1.6%-6.6%), stroke (Intuity 0.36%-1.4% and Perceval 0%-0.8%), MI (Intuity 0.07%-0.26%), and SVD (Intuity 0.12%-0.7% and Perceval 0%) were comparable. Compared to standard full sternotomy (SFS), minimally invasive surgery (MINV) mortality ranged from 0% to 4.3% for MINV and 0%-2.1% for SFS. Hospital costs outcomes ranged from $37,187-$44,368 for the Intuity, $69,389 for TAVR, and $13,543 for SB. Intuity short-term mortality ranged between 0.9% and 12.4% while long-term mortality ranged between 2.6% and 20%. CONCLUSIONS: This manuscript provides a 360° overview of the current rapid deployments, sutureless, and TAVR prosthesis.

INTRODUCTION: Robotic-assisted coronary artery bypass grafting (CABG) outcomes in patients with a high society of thoracic surgery (STS) score in urgent settings remain hindered. PRESENTATION OF CASE: A high-risk female patient presented with dyspnea and low ejection fraction (EF = 15%) and was diagnosed with pulmonary edema post myocardial infarction. She was medically stabilized with intraaortic balloon pump and the heart-team decided to intervene with off-pump robotic hybrid coronary revascularization (HCR). The patient had the planned with left internal mammary artery (LITA) anastomosis to the left anterior descending artery (LAD) and the postoperative recovery was uneventful and patients discharged after few days at home. DISCUSSION: CABG has proven to be superior to percutaneous coronary intervention (PCI) even when guided by fractional flow rate and using the last generation stents according to fractional flow reserve versus angiography for multivessel evaluation 3 clinical trial. In moderate SYNTAX score patients that have been historically (SYNTAX trial) treated with multivessels PCI, robotic CABG has been shown to offer the advantage of LITA-LAD in combination with stent for non-LAD territory. CONCLUSION: High-risk, fragile patients, with low EF and high STS score that undergo urgent CABG can benefit from heart-team collaboration, and HCR is an important tool in the armamentarium.

OBJECTIVE: Despite minimally invasive techniques having gained wider application in cardiac surgery, current evidence on minithoracic aortic surgery is still limited. The aim of this study was to compare early and midterm outcomes of patients undergoing operations of the proximal thoracic aorta through ministernotomy (MS) versus full sternotomy (FS). METHODS: Data from 624 consecutive patients who underwent proximal aortic repair through MS (n = 214, 34.3%) and FS (n = 410, 65.7%) at two aortic centers were analyzed. Treatment selection bias was addressed using propensity score matching (MS vs. FS). After matching, two well-balanced groups of 202 patients each were created. RESULTS: Median cardiopulmonary bypass and cross-clamp times were 88 and 68 min, respectively, with no difference between groups. Overall, 30-day mortality was 1% (n = 2) in MS and 0.5% (n = 1) in FS (p = .6). No difference was found in the rates of stroke (MS n = 5, 2.5%; FS n = 5, 2.5%), dialysis (MS n = 1, 0.5%; FS n = 4, 2%), bleeding (MS n = 7, 3.5%; FS n = 7, 3.5%), and blood transfusions (MS n = 67, 33.3%; FS n = 57, 28.4%). Patients receiving MS showed a lower incidence of respiratory insufficiency compared with FS (0% vs. 2.5%, p = .04). Intensive care unit and hospital stays were similar between groups. Two-year survival rate was 97.2% in MS and 96.5% in FS (p = .9). CONCLUSIONS: Mini proximal aortic operations can be performed successfully without compromising the proven efficacy and safety of conventional access. In selected patients, MS was associated with very low mortality and morbidity rates. Additionally, MS demonstrated superior clinical outcomes as regards respiratory adverse events, when compared with FS.

We present the case of a type A aortic dissection originating from the right coronary ostium and an intraoperative diagnosis of the entire coronary artery system originating from a single right-sided coronary ostium.
