Objective The aim of this study was to define the relative role of a right minithoracotomy (RT) versus standard median sternotomy (ST) for open aortic valve replacement (AVR). Methods A retrospective analysis was performed of all 1348 patients undergoing isolated, open AVR at a single institution during a 14-year period. Because relatively few patients were technically suitable for redo AVR with the RT approach (n = 20), all redo patients (n = 209) were excluded, leaving 1139 patients available for analysis. Patients converting from RT to ST approach (n = 15) were analyzed separately. Results Relative to ST (n = 672), the RT patients (n = 452) were older with more stenosis but with more recent operation year, lower rate of congestive heart failure, higher ejection fraction, lower rate of endocarditis, and lower rate of renal disease than the ST AVR patients (all P < 0.0001). Right minithoracotomy AVR was associated with longer cardiopulmonary bypass times [157 (25) vs 131 (38), P = 0.0004] and clamp times [103 (20) vs 85 (27), P < 0.0001] but less transfusion (1.4 vs 3.4 U, P = 0.0003), less chest tube output (405 vs 950 mL, P < 0.0001), fewer reoperations for bleeding (0.4% vs 4%, P < 0.0001), shorter length of stay (6 vs 8 days, P = 0.03), and lower rate of atrial fibrillation (15% vs 20%, P = 0.03). Stroke, operative mortality, and survival were not significantly different between the groups. Conclusions Given the biases of retrospective propensity-adjusted analysis, these data suggest that RT AVR is a safe alternative to ST AVR in selected patients, with advantages of avoiding sternotomy with associated bleeding, transfusion, and delayed wound healing, at the expense of longer pump and clamp times.

Abstract Background The advantage of minimally invasive sternotomy (MS) over full sternotomy (FS) for isolated aortic valve replacement (AVR) is still controversial. We aimed to examine if J-shaped MS is a safe alternative to FS in patients undergoing primary isolated AVR. This study is a retrospective and restricted cohort study that included 137 patients who had primary isolated AVR from February 2013 to June 2015. Patients with previous cardiac operations, low ejection fraction (< 40%), infective endocarditis, EuroSCORE II predicted mortality > 10%, and patients who had inverted T or inverted C-MS or right anterior thoracotomy were excluded. Patients were grouped into the FS group (n=65) and MS group (n=72). Preoperative variables were comparable in both groups. The outcome was studied, balancing the groups by propensity score matching. Results Seven (9%) patients in the MS group were converted to FS. Cardiopulmonary bypass (98.5 ± 29.3 vs. 82.1 ± 13.95 min; p ≤ 0.001) and ischemic times (69.1 ± 23.8 vs. 59.6 ± 12.2 min; p = 0.001) were longer in MS. The MS group had a shorter duration of mechanical ventilation (10.1 ± 11.58 vs. 10.9 ± 6.43 h; p = 0.045), ICU stay (42.74 ± 40.5 vs. 44.9 ± 39.3; p = 0.01), less chest tube drainage (385.3 ± 248.6 vs. 635.9 ± 409.6 ml; p = 0.001), and lower narcotics use (25.14 ± 17.84 vs. 48.23 ± 125.68 mg; p < 0.001). No difference was found in postoperative heart block with permanent pacemaker insertion or atrial fibrillation between groups (p = 0.16 and 0.226, respectively). Stroke, renal failure, and mortality did not differ between the groups. Reintervention-free survival at 1, 3, and 4 years was not significantly different in both groups (p = 0.73). Conclusion J-ministernotomy could be a safe alternative to FS in isolated primary AVR. Besides the cosmetic advantage, it could have better clinical outcomes without added risk.

Background: Several risk factors, including emergency surgery, predicted early mortality after aortic valve replacement (AVR).  Euroscore II is used to predict the mortality after cardiac operations. We aimed to review our experience in AVR and determine the early mortality predictors Methods: We collected the data of 200 rheumatic patients who had standard AVR in two centers. Median sternotomy and cardiopulmonary bypass were used in all patients. Transcatheter and minimally invasive aortic valve replacement patients were excluded. We used 15 types of aortic valve prostheses, either mechanical or biological. Follow-up echocardiography was done in the intensive care unit, on discharge, and one month after discharge.     Results: 128 patients (64%) had mechanical AVR, and 130 patients (65%) were males. The mean age was 48.2 ± 19 years, and body mass index was 1.8 ± 0.2 Kg/m2. The mean preoperative ejection fraction was 54 ± 9.4 %, end-diastolic dimension was 5.3 ± 0.8 cm, and end-systolic dimension was 3.5 ± 0.9 cm. Nine patients (4.5%) died in the early postoperative period (6 months). Euroscore II was the only factor significantly associated with early mortality (P value= 0.031).  The mean Euroscore II was 1.3 ± 0.9 and 10.1 ± 10.7 for survivors and non-survivors, respectively.  Conclusion: Euroscore II score was significantly associated with early mortality after aortic valve replacement in rheumatic patients and can be used for risk stratification in those patients.

Background: Previous studies have shown that female gender is an independent predictor of increased operative mortality after coronary artery bypass surgery. It remains inconsistent whether female gender is associated with increased mortality after aortic valve replacement (AVR). The purpose of this study is to investigate the role of female gender inoperative mortality after AVR. Methods: The study population included isolated AVR performed between January 2003 and December 2012 at a single Instituation. Results: During this period, 1,262 patients underwent isolated AVR. The major preoperative characteristics and operative outcomes are detailed in the following table. R>Conclusions: In this study, female patients had increased operative mortality after isolated AVR.

Background: Data regarding association of elevated cardiac enzymes and adverse outcomes in patients who undergo aortic valve replacement (AVR) has been inconclusive. Role of coronary revascularization prior to AVR remains uncertain. We sought to understand prognostic implication of post procedure troponin T (TnT) elevation in patients undergoing AVR. Hypothesis: We hypothesized that patients with significantly elevated TnT after AVR will have worse outcomes representing important coronary circulation which is not revascularized. Methods: We retrospectively studied 4648 consecutive patients who underwent AVR at a single tertiary care center between January 2007 and December 2013. These were divided into surgical AVR (SAVR) and transcatheter AVR (TAVR). Median post procedure peak TnT was identified in the SAVR and TAVR groups. Patients were divided into quartiles based on median TnT level. Results: Of 4648 patients who underwent AVR, 4200 (66% male) were SAVR and 448 (59% male) were TAVR. Median post procedure peak TnT values in the TAVR and SAVR group were 0.19 [0.08-0.39] & 0.36 [0.22-0.64] respectively (p<0.001). 6 month mortality was 1.5% (65/4200) in SAVR cases and 2.7% (12/448) in TAVR cases (p=0.08). In patients with TnT less than 50 th percentile, 6 month mortality was 0.7% & 1.8% after SAVR & TAVR respectively (p=0.1). In patients with TnT higher than 50 th percentile, 6 month mortality was 2.4% & 3.6% after SAVR & TAVR respectively (p=0.26). In the SAVR group, mortality was 0.7% in patients with TnT levels less than 50 th percentile & 2.4% in patients with TnT higher than 50 th percentile (p<0.001). See Figure. Conclusion: Peak troponin T was significantly higher after SAVR as compared to TAVR. Higher post procedure peak TnT is associated with increased 6 month mortality. These results are highly significant in the SAVR group. The mechanism and significance of these findings requires further studies.

Right Thoracotomy

Background Minimally invasive surgical approaches have gained popularity among patients and surgeons. The aim of this project was to assess the safety of initiating aortic valve replacement via an anterior right thoracotomy program. Methods Between May 2015 and May 2019, data of all isolated primary aortic valve replacements were extracted retrospectively from our prospectively collected database and categorized into conventional median sternotomy, hemisternotomy, and anterior right thoracotomy cases. In total, 661 patients underwent isolated primary aortic valve replacement, of whom 429 (65%) had a median sternotomy, 126 (19%) had a hemisternotomy, and 106 (16%) had an anterior right thoracotomy. Preoperative characteristics were similar in each of the three groups. Statistical testing of the surgical groups was undertaken using the chi-square test for categorical variables and one-way analysis of variance with Tukey post-hoc pairwise tests (where appropriate) for continuous variables, to identify differences between pairs of data. Results Cardiopulmonary bypass and crossclamp times were significantly longer in the anterior right thoracotomy group compared to the hemisternotomy and median sternotomy groups ( p < 0.001). Blood loss was significantly less and hospital stay significantly shorter in the hemisternotomy group compared to median sternotomy group but not the anterior right thoracotomy group. Mortality, stroke, renal, gastrointestinal and respiratory complications showed no statistical differences. Conclusion Surgical aortic valve replacement had a very low mortality and morbidity in our experience, and it is safe to start a minimal access program for aortic valve replacement.
