Synchronous bilateral lung lesions are emerging as a common but tricky disease for surgical management. Whether one or two-stage surgery should be taken remains in debate. We retrospectively analysed 151 patients who underwent one and two-stage Video Assisted Thoracic Surgery (VATS) to investigate the safety and feasibility of the two surgical approaches. A total of 151 patients were included in the study. Propensity score matching was performed to minimize the baseline characteristics difference between one and two-stage groups. Clinical factors including in-hospital days after surgery, chest tube drainage days, types and severity of post-operative complications were compared between the two groups. Logistic univariate and multivariate analyses were used to find the risk factors for post-operative complications. Nomogram was built to select the low risk candidates for the one-stage VATS. After propensity score matching, 36 one-stage and 23 two-stage patients were enrolled. The age (p = 0.669), gender (p = 0.3655), smoking status (p = 0.5555), pre-operative comorbidity (p = 0.8162), surgical resection (p = 0.798) and lymph node dissection (p = 9036) were balanced between the two groups. There was no difference in post-surgery hospital days (8.67 ± 2.68 versus 8.46 ± 2.92, p = 0.7711) and chest tube retaining days (5.47 ± 2.20 versus 5.46 ± 1.95, p = 0.9772). Moreover, post-operative complications also showed no difference between one-stage and two-stage groups (p = 0.3627). Univariate and multivariate analysis revealed that advanced age (p = 0.0495), pre-surgical low haemoglobin (p = 0.045) and blood loss (p = 0.002) were risk factors for post-operative complications. Nomogram built with the three risk factors showed reasonable predictive value. One-stage VATS for synchronous bilateral lung lesion patients was proved to be a safety procedure. Advanced age, pre-surgical low haemoglobin and blood loss may predict complications after surgery.

Abstract
Objective
The treatment of active infective endocarditis (IE) presents a clinical dilemma with uncertain outcomes. This study sets out to determine the early and intermediate outcomes of patients treated surgically for active IE at an academic medical center.
Methods
A retrospective chart review was conducted to identify patients who underwent surgical intervention for IE at our institution from July 1st, 2011 to June 30th, 2018. In-patient records were examined to determine etiology of disease, surgical intervention type, postoperative complications, length of stay (LOS), 30-day in-hospital mortality, and 1-year survival.
Results
Twenty-five patients underwent surgical intervention for active IE. The average age of the patients was 47 ± 14 years old and most of the patients were male (N = 15). The majority of the patients had the mitral valve replaced (N = 10), with the remaining patients having tricuspid (N = 8) and aortic (N = 7) valve replacements. The etiology varied and included intravenous drug use (IVDU), and presence of transvenous catheters. The 30-day in-hospital mortality was 4% with 1 patient death and the 1-year survival was 80%. The average LOS was 27 days ±15 and the longest LOS was 65 days.
Conclusions
Surgical management of IE can be difficult and challenging however mortality can be minimized with acceptable morbidity. The most common complication was CVA. The average LOS is longer than traditional adult cardiac surgery procedures and the recurrence rate of valvular infection is not minimal especially if the underlying etiology is IVDU.

Sternal wound infections (SWI) continue to be a major cause of concern after cardiac surgery. It leads to prolonged hospital stay and increased morbidity, mortality and increased hospital costs. Prophylactic systemic antibiotics have been used to prevent surgical site infection (SSI). However, prolonged postoperative use of systemic antibiotics can lead to emergence of resistant organisms. Gentamycin Containing Collagen Implants (GCCI) when used during sternotomy closure produces high local antibiotic concentrations in the wound with a low serum concentration. There is evidence that the concentration of gentamicin in the mediastinal fluid reaches levels high enough to be effective against bacteria that are considered resistant to gentamycin and other antibiotics. However, questions have been raised about the safety and efficacy of GCCI. There were concerns whether GCCI can lead to systemic absorption with renal impairment and whether use of topical antibiotics can lead to emergence of antimicrobial resistance. We, hereby, review the literature on GCCI (Collatamp) and take the opportunity to appraise the scientific community about their role in cardiac surgery. Several recent studies have supported their clinical effectiveness. They should be used in dry condition and should not be soaked in saline even for a short period prior to use. However, for GCCI to become part of routine practice in cardiac surgery further large randomised studies are required. As the incidence of sternal wound infection is low in the specialty of cardiac surgery, for any study to be sufficiently powered to address this issue, multicenter studies might be the way forward. Based on the evidence presented in this manuscript it is recommended GCCI (Collatamp) can be a cost effective adjunct for prevention of sternal wound infection. They can also be used for treatment of Deep Sternal Wound Infection.

Yongxia Zhang
Abstract
Background
Chronic heart failure (CHF) is regarded as common clinical heart disease. This study aims to investigate the clinical diagnostic value of echocardiography (Echo) and serum C-reactive protein (CRP) levels in patients with CHF.
Methods
A total of 75 patients with CHF (42 males, 33 females, age 62.72 ± 1.06 years) were enrolled as study subjects, with 70 non-CHF subjects (38 males, 32 females, age 62.44 ± 1.28 years) as controls. The left ventricular ejection fraction (LVEF), fraction shortening rate of the left ventricle (FS), and early to late diastolic filling (E/A) were determined by Echo, followed by an examination of the expression of serum CRP by ELISA. In addition, the Pearson method was used to analyze the correlation between echocardiographic quantitative parameters (EQPs) (LVEF, FS, and E/A) and serum CRP levels. Receiver operating characteristic (ROC) curve was adopted to evaluate the diagnostic efficacy of EQPs and serum CRP levels for CHF. The independent risk factors for CHF patients were measured by logistics regression analysis.
Results
The serum CRP level of CHF patients was elevated, the values of LVEF and FS decreased, and the E/A values increased. ROC curve revealed that the EQPs (LVEF, FS, and E/A) combined with serum CRP had high diagnostic values for CHF patients. Logistic regression analysis showed that the EQPs (LVEF, FS, and E/A) and serum CRP levels were independent risk factors for CHF patients.
Conclusion
Echo combined with serum CRP level has high clinical diagnostic values for CHF patients.

The study was designed to evaluate the effects of moderate prosthesis-patient mismatch (defined as 0.65 cm2/m2 < indexed effective orifice area ≤ 0.85 cm2/m2) on midterm outcomes after isolated aortic valve replacement with a 17-mm St. Jude Medical Regent valve in a large series of patients, and to determine if these effects are influenced by patient confounding variables. One-hundred and six patients with and without moderate prosthesis-patient mismatch early after implantation of a 17-mm Regent valve at aortic position were included. Both clinical and echocardiographic assessments were performed preoperatively, at discharge and during follow-up period (mean follow-up time 52.6 ± 11.9 months). The prevalence of moderate prosthesis-patient mismatch was documented in 46 patients (43.4%) at discharge. During the follow-up period, no difference in the regression of left ventricular mass, decrease of transvalvular pressure gradients, mortality and prosthesis-related complications was observed between patients with and without moderate prosthesis-patient mismatch. After adjustment for several risk factors, moderate prosthesis-patient mismatch was associated with increased midterm mortality in patients with baseline left ventricular ejection fraction < 50% (HR: 1.80, p = 0.02), but with normal prognosis in those with preserved LV function. Younger age (cut off value = 65 years) was not an independent predictor of increased midterm mortality and valve-related complications in patients with moderate prosthesis-patient mismatch. Moderate prosthesis-patient mismatch after aortic valve replacement with a small mechanical prosthesis is associated with increased mortality and adverse events in patients with pre-existing left ventricular dysfunction. Selected patients with small aortic annulus can experience satisfactory clinical improvements and midterm survival after aortic valve replacement with a 17-mm Regent valve.

Early mobility is considered important in minimising pulmonary complication, length of stay (LOS) and enhancing recovery following major surgery. We aimed to observe and measure the reduction in early postoperative physical activity following major thoracic surgery, identifying any potentially limiting factors, and factors predictive of reduced activity. Patients undergoing thoracotomy and lung resection were prospectively observed for the purposes of this study. All patients were routinely assisted to mobilise by physiotherapists from postoperative day 1, and continued daily with exercise and progression of mobility as per usual practice. Physical activity was measured with SenseWear Pro 3 armband physiologic motion sensors between postoperative day 1–4. The motion sensors recorded step count, time spent in ‘sedentary’/ ‘moderate’ activity, and energy expenditure. Frequency of postoperative pulmonary complication (PPC) and postoperative LOS were also observed. Multivariate analyses were performed using forward stepwise logistic regression; results are displayed as odds ratio (95% confidence intervals). n = 99, median (interquartile range) steps 472 (908) over combined postoperative days 2/ 3, sedentary activity (<3 METs) 99%. Less active subjects reported significantly more pain on day 2 and 3 (p = 0.013/ 0.00 respectively) (p < 0.001). On regression analysis age ≥75 years, predicted FEV1 < 70% and poor preoperative activity were predictive of lower postoperative activity. Factors limiting mobility on day 1 included pain and dizziness. Median LOS was longer (p = 0.013) (6 vs. 5 days) in less active patients and frequency of PPC was 20% vs 4% (p = 0.034). Physical activity following major thoracic surgery is generally very limited, with less active patients demonstrating longer LOS. Factors limiting immediate postoperative mobility were largely modifiable, some of the factors predictive of lower activity were also possibly modifiable/amenable to physiotherapy or pulmonary rehabilitation. Prompt assessment and recognition of these factors is needed in future, with timely and effective management incorporated into care pathways to maximise each patients potential to mobilise postoperatively.

Survival and aortic-related adverse events after thoracic endovascular aortic repair (TEVAR) for aortic intramural hematoma (IMH) and aortic dissection (AD) are controversial. We aimed to assess the preoperative characteristics and to evaluate TEVAR outcomes of acute type B IMH and AD. Between June 2002 and May 2021, 83 patients with acute type B IMH and 755 patients with acute type B AD underwent TEVAR at the General Hospital of Northern Theater Command. We retrospectively analyzed data from these patients, including clinical characteristics and follow-up outcomes. The patients with IMH were significantly older than the ones with AD (P < 0.001). Diabetes mellitus (P = 0.035) and ischemic cerebrovascular disease (P = 0.017) were more common in the IMH group than in the AD group. The results demonstrated a less long-term aortic-related death-free survival rate in the IMH group than the AD group for all the patients (P = 0.014) and the matched patients (P = 0.027). It also presents a lower long-term overall survival rate (P = 0.047) and aortic-related event-free rate (P = 0.048) in the IMH group than in the matched patients. Compared with AD patients, patients with IMH who underwent TEVAR had a worse long-term outcome of aortic-related survival in all and matched patients.
