ABSTRACT

Prophylactic left atrial appendage occlusion has been suggested as a means of reducing cardioembolism risk in patients with atrial fibrillation. Its clinical benefits have been discussed together with potential endocrine or hemodynamic adverse effects, with conflicting conclusions. We aimed to provide a thorough overview of the current literature and a recommendation for daily clinical decision-making. A comprehensive Medline search through PubMed was conducted to search for relevant articles, which were further filtered using the title and abstract. Sixty-five articles were selected as relevant to the topic. Concomitant left atrial appendage occlusion during cardiac surgery for other reasons is effective in terms of thromboembolism risk reduction in patients with a history of atrial fibrillation and higher CHA2DS2-VASc scores. Surgical occlusion is safe, and epicardial closure techniques are preferred. Thoracoscopic and transcatheter techniques are also feasible, and the individual treatment choice must be tailored to the patient. The concerns about endocrine imbalance or risk of heart failure after occlusion are not supported by evidence. Current evidence is conflicting with regard to hemodynamic consequences of appendage occlusion.

ABSTRACT

Pure aortic regurgitation and dilation of aortic annulus are the most significant risk factors for the failure of pulmonary autograft after the Ross procedure. Aortic annuloplasty has a positive effect on the durability of the autograft. Previously, we described a technique for external annuloplasty with dedicated CORONEO ring. In the present manuscript, we suggest the sizing of annuloplasty based on the diameter of pulmonary autograft annulus.

ABSTRACT

Introduction: The effect of bone wax on sternal infection and intraoperative bleeding in off-pump coronary surgery has not been reported in current literature. Aim: To prospectively evalute this in a cohort of high risk patients undergoing off-pump coronary artery surgery at our institution. The potential impact on cell saver utilization was also studied. Material and methods: A prospective randomized study was performed in 58 diabetic patients operated on for two-vessel coronary artery disease by the off-pump technique. They were randomly assigned to the wax or no-wax group. Results: There was no significant difference in intraoperative blood loss between the wax (550 ml) and no-wax group (750 ml; p = 0.0711). In multivariate analysis the absence (non-use) of bone wax (odds ratio = 3.9 (1.12-13.51), p = 0.027) and preoperative creatinin level (odds ratio = 1.1 (0.99-1.03), p = 0.03) were identified as independent predictors of blood loss ≥ 750 ml. The number of red blood cell units during hospital stay was similar in both groups (p = 0.42). Wound healing complications were not observed in either group. Conclusions: The use of bone wax does not lead to a higher risk of sternal wound infection. It may reduce the risk of high intraoperative blood loss, thus avoiding the need of a cell saver during off-pump coronary surgery. However, this influence remains questionable.

ABSTRACT

Background: Invasive double-valve endocarditis with structural damage (abscess or perforation) of the aorto-mitral curtain is a relatively rare but fatal diagnosis requiring complex surgical reconstruction. This study presents the short-term and mid-term outcomes from a single center. Methods: From 2014 to 2021, 20 patients with double-valve endocarditis with structural damage of the aorto-mitral curtain underwent surgical reconstruction (Hemi-Commando procedure n = 16 and Commando procedure n = 4). Data were obtained retrospectively. Results: In 13 cases, the procedure was a reoperation. The mean cardiopulmonary bypass time was 239 ± 47 min and the mean cross-clamp time was 186 ± 32 min. Concomitant procedures were tricuspid valve repair in two, coronary revascularization in one, closure of a ventricular septal defect in one and hemiarch (using circulatory arrest) in one patient. Eleven patients (55%) required surgical revision for bleeding. Thirty-day mortality was 30% (6 patients)-3 patients from the Hemi-Commando group (19%) and 3 patients from the Commando group (75%). Overall survival at 1, 3 and 5 years was 60%, 50% and 45% respectively. Reoperation was required by 4 patients. Freedom from reoperation at 1, 3 and 5 years was 86%, 71% and 71% respectively. Conclusion: Despite the high postoperative morbidity and mortality, complex surgical reconstruction of the aorto-mitral continuity of patients with double-valve endocarditis represents the only real chance for survival. Mid-term outcomes are acceptable, but strict follow-up is required due to the risk of valve failure.

ABSTRACT

Background: Renal cell carcinoma (RCC) with tumor thrombus extension into the right atrium (level IV) is a rare life-threatening clinical condition that can only be managed by means of a combined urological and cardiac surgical approach. The early and late outcomes of this radical treatment were analyzed in a large single-institution series over a period of 30 years. Methods: In 37 patients with RCC and intracardiac tumor thrombus extension, nephrectomy was performed followed by the extraction of the intracaval and intracardiac tumor thrombus under direct visual control during deep hypothermic circulatory arrest (DHCA). Recently, in 13 patients, selective aortic arch perfusion (SAAP) was instituted during DHCA. Results: In all patients, precise removal of the tumor thrombus was accomplished in a bloodless field. The mean duration of isolated DHCA was 15 ± 6 min, and 31.5 ± 10.2 min in the case of DHCA + SAAP, at a mean hypothermia of 22.7 ± 4°C. In-hospital mortality was 7.9% (3 patients). In Kaplan-Meier analysis, the estimated median survival was 26.4 months whereas the 5-year cancer-related survival rate was 51%. Conclusions: Despite its complexity, this extensive procedure can be performed safely with a generally uneventful postoperative course. The use of cardiopulmonary bypass with DHCA, with the advantage of SAAP, allows for a safe, precise, and complete extirpation of intracaval and intracardiac tumor mass. Late outcomes after radical surgical treatment in patients with RCC and tumor thrombus reaching up in the right atrium in our series justify this extensive procedure.

ABSTRACT

BACKGROUND: Tobacco smoking has been associated with an increased risk of complications after conventional coronary surgery. However, the impact of smoking on the risk of postoperative complications in minimally invasive coronary surgery is yet to be studied. We aimed to analyze the impact of the preoperative smoking status on the short- and long-term outcomes of minimally invasive direct coronary artery bypass grafting (MIDCAB) in the context of isolated surgical revascularization or in association with percutaneous coronary intervention. METHODS: This was a retrospective observational study of all patients undergoing MIDCAB at our institution between 2006 and 2020. Patients were divided into three groups: active smokers, ex-smokers who have quit smoking for at least 1 month before surgery, and non-smokers. The groups were compared using conventional statistical methods. Multivariate analysis was then performed where significant differences were found to eliminate bias. RESULTS: Throughout the study period, 541 patients underwent MIDCAB, of which 135 (25%) were active smokers, 183 (34%) were ex-smokers, and 223 (41%) were non-smokers. Smokers presented for surgery at a younger age (p < 0.0001), more frequently with a history of myocardial infarction (p < 0.001), peripheral artery disease (p < 0.001) and chronic obstructive pulmonary disease (p < 0.0001). Using multivariate analysis, active smoking was determined to be a significant risk factor for the need of urgent revascularization (odds ratio 2.36 [1.00-5.56], p = 0.049) and the composite of pulmonary complications (including pneumothorax, respiratory infection, respiratory dysfunction, subcutaneous emphysema and exacerbation of chronic obstructive pulmonary disease; odds ratio 2.84 [1.64-4.94], p < 0.001). Preoperative smoking status did not influence the long-term survival (p = 0.83). CONCLUSIONS: In our study, active smokers presented for MIDCAB at a younger age and more often with signs of atherosclerotic disease (history of myocardial infarction and peripheral artery disease). Active smoking was found to be the most significant risk factor for postoperative pulmonary complications, and is also associated with a more frequent need for urgent surgery at diagnosis. Long-term postoperative survival is not affected by the preoperative smoking status.

ABSTRACT

BACKGROUND: The prevalence and outcomes of the unicuspid aortic valve (UAV) in patients undergoing the Ross procedure have been strongly underreported in the current literature. We sought to evaluate this in comparison with bicuspid (BAV) and tricuspid valve (TAV) in our Ross cohort. METHODS: This was a retrospective observational study of patients undergoing the Ross procedure at 2 dedicated centers between 2009 and 2020. Primary end points were the risks of midterm autograft reoperation and the onset of at least moderate aortic regurgitation during follow-up. The secondary end point was to compare the perioperative outcomes between the groups. RESULTS: Included in the analysis were 286 patients, of those 39% with UAV, 52% with BAV, and 9% with TAV. UAV patients were operated on at the youngest age (P < .001) and more often for a combined hemodynamic aortic valve pathology (P = .02). They had the largest aortic root dimensions: annulus (P = .01), Valsalva sinuses (P = .11), sinotubular junction (P = .001), and ascending aorta (P < .0001). The risks of reoperation (P = .86) and the onset of aortic regurgitation (P = .75) were comparable among the groups over the follow-up of 4.1 years. There was no difference in perioperative outcomes. CONCLUSIONS: UAV is a separate unit characterized by a distinct hemodynamic pathology and generated aortopathy. It is not associated with a higher risk of reoperation or new onset of aortic regurgitation after the Ross procedure in the midterm postoperatively. At the current state, UAV remains acceptable for the Ross procedure.

ABSTRACT

Background: Robotic assistance (RA) in the harvesting of internal thoracic artery during minimally invasive direct coronary artery bypass grafting (MIDCAB) provides several potential benefits for surgeon and patient in comparison with conventional MIDCAB. The two technical options have not been thoroughly compared in the literature yet. We aimed to perform this in our cohort with the use of propensity-score matching (PSM). Methods: This was a retrospective comparison of all consecutive patients undergoing conventional MIDCAB (2005-2021) and RA-MIDCAB (2018-2021) at our institution with the use of PSM with 27 preoperative covariates. Results: Throughout the study period 603 patients underwent conventional and 132 patients underwent RA-MIDCAB. One hundred and thirty matched pairs were selected for further comparison. PSM successfully eliminated all preoperative differences. Patients after RA-MIDCAB had lower 24 h blood loss post-operatively (300 vs. 450 ml, p = 0.002). They had shorter artificial ventilation time (6 vs. 7 h, p = 0.018) and hospital stay (6 vs. 8 days, p < 0.001). There was no difference in the risk of perioperative complications, short-term and mid-term mortality between the groups. Conclusions: RA-MIDCAB is an attractive alternative to conventional MIDCAB. It is associated with lower post-operative blood loss and potentially faster rehabilitation after surgery. The mortality and the risk of perioperative complications are comparable among the groups.

ABSTRACT

Background: Unicuspid aortic valve (UAV) is the second most common underlying cause of aortic valve dysfunction in young adults after the bicuspid valve. The valve may be replaced (for example by pulmonary autograft) or repaired using the bicuspidization technique. The aim of our study was to compare short- and mid-term outcomes of Ross procedure with bicuspidization in patients with severe UAV dysfunction. Methods: This was a multi-center retrospective observational cohort study comparing data from two dedicated Ross centers in the Czech Republic with bicuspidization outcomes provided by AVIATOR registry. As for the Ross group, only the patients with UAV were included. Primary endpoint was mid-term freedom from reintervention. Secondary endpoints were mid-term freedom from major adverse events, endocarditis and pacemaker implantation. Results: Throughout the study period, 114 patients underwent the Ross procedure (years 2009-2020) and 126 patients underwent bicuspidization (years 2006-2019). The bicuspidization group was significantly younger and presented with a higher degree of dyspnea, a lower degree of aortic valve stenosis and more often with pure regurgitation. The primary endpoint occurred more frequently in the bicuspidization group than in the Ross group - 77.9 vs. 97.9 % at 5 years and 68.4 vs. 75.2 % at 10 years (p < 0.001). There was no difference in secondary endpoints. Conclusion: Ross procedure might offer a significantly lower mid-term risk of reintervention than bicuspidization in patients with UAV. Both procedures have comparable survival and risk of other short- and mid-term complications postoperatively.

ABSTRACT

Introduction: Primary cardiac tumors are a rare condition presenting with a variety of symptoms. The outcomes of their surgical treatment in the modern era from central Europe have not been recently reported. Aim: To evaluate the short- and long-term outcomes of the cardiac tumor operations at our department throughout the last 20 years. Material and methods: This was a retrospective analysis of all primary cardiac tumor operations performed at our institution between 2000 and 2020. Perioperative data were extracted from patient records. Long-term data were provided by the National Registry of Cardiac Surgery. Results: Sixty procedures for primary cardiac tumor were performed throughout the study period. The most common type of tumor was myxoma (88%), followed by fibroelastoma (8%), lipoma (2%) and sarcoma (2%). There were 2 perioperative deaths (3%). The most common perioperative complication was atrial fibrillation (47%). One (2%) patient underwent reoperation 6 years later because of myxoma recurrence. We recorded 13 long-term deaths, but only 1 patient died as a consequence of cardiac tumor (sarcoma) 15 months after the surgery. Long-term survival of the cohort was comparable with the age- and sex-matched general population up to 15 years postoperatively (relative survival 0.91, CI 0.68-1.23). Rich histopathological illustrations are provided in the online supplementary material. Conclusions: Surgical resection is the standard treatment of primary cardiac tumors. The outcomes of benign tumors are excellent and the long-term postoperative survival is comparable with the general population. The prognosis of malignant tumors remains poor.

ABSTRACT

OBJECTIVES: The choice of optimal surgical treatment for young and middle-aged adults with aortic valve disease remains a challenge. Mechanical aortic valve replacement (mAVR) is generally preferred despite promising recent outcomes of the Ross procedure. Our goal was to compare the strategies at a nationwide level. METHODS: This study was a retrospective analysis of prospectively recorded data from the National Registry of Cardiac Surgery of the Czech Republic. Using propensity score matching, we compared the outcomes of patients undergoing the Ross procedure in 2 dedicated centres with all mAVRs performed in country between 2009 and 2020. RESULTS: Throughout the study period, 296 adults underwent the Ross procedure and 5120 had an mAVR. We found and compared 291 matched pairs. There were no in-hospital deaths, and the risk of perioperative complications was similar in both groups. Over the average follow-up period of 4.1 vs 6.1 years, the Ross group had a lower all-cause mortality (0.7 vs 6.5%; P = 0.015). This result remained significant even when accounting for cardiac- and valve-related deaths only (P = 0.048). Unlike the Ross group, the mAVR group had a significantly lower relative survival compared with the age- and sex-matched general population. There was no difference in the risk of reoperation (4.5 vs 5.5%; P = 0.66). CONCLUSIONS: The Ross procedure offers a significant midterm survival benefit over mAVR. The procedures have a comparable risk of perioperative complications. Patients after mAVR have reduced survival. Thus, the Ross procedure should be the preferred treatment option for young and middle-aged adults with aortic valve disease in dedicated centres.

ABSTRACT

OBJECTIVES: Patients with a bicuspid aortic valve (BAV) often present with a dilated ascending aorta. However, the underlying pathogenesis for the observed changes in the aortic wall and the resulting aneurysmal dilation remains a subject of debate. This study aims to compare the histological abnormalities of the ascending aorta in BAV and tricuspid aortic valve (TAV) patients and their correlation with aortic diameter and patient age. METHODS: A total of 376 patients from our institution's clinical database were included in the retrospective analysis. These patients underwent either elective surgery for ascending aorta dilation or emergency surgery for aortic dissection, either isolated or with a structurally diseased aortic valve. After excision, the ascending aorta samples were analysed by a pathologist. RESULTS: On histological examination, a higher degree of elastic fibre fragmentation and loss and mucoid extracellular matrix accumulation was present in the samples from TAV patients when compared with that from BAV patients (P < 0.001). However, correlation was poor for all variables when considering aortic diameter and histological abnormalities or age and histological abnormalities in both BAV and TAV patients. CONCLUSIONS: Our study demonstrates a greater incidence of severe histological abnormalities in TAV patients when compared with BAV patients.

ABSTRACT

Objectives. The One-minute Sit-To-Stand Test (STST) is a relatively novel physical performance test in the field of pulmonology. It measures the exercise tolerance of the patient. In this pilot study, we evaluated its predictive value for the postoperative course in cardiac surgery patients. Design. This was a prospective observational cohort study of patients undergoing elective aortic valve replacement. STST was applied in the patients, along with pulmonary function testing, a day prior to surgery, on postoperative day 7, and 3 months after surgery. A Short Form-36 health related quality of life survey (SF-36) was also included. The patients were divided into two groups according to the preoperative STST outcome: group A (≤20 repetitions, n = 12), and group B (>20 repetitions, n = 18). Results. We enrolled 30 patients in the study between May 2017 and May 2019. No complication were observed during the STST. The standard perioperative measures were identical for both groups. However, group A exhibited a significantly longer artificial ventilation time, as well as worse pulmonary function (VC, FVC, TLCO), on postoperative day 7. Concerning the SF-36, group A displayed a worse pre- and postoperative evaluation in both physical functioning and vitality. Conclusions. STST is a short and practical physical performance test that could enable a better prediction of the postoperative course after cardiac surgery. Patients with lower preoperative STST performance may require longer postoperative artificial ventilation, as they may present worse in some parameters of pulmonary functions and quality of life. However, these findings must be corroborated in larger studies.

ABSTRACT

Background: Single-lung ventilation facilitates surgical exposure during minimally invasive cardiac surgery. However, a deeper knowledge of antibiotic distribution within a collapsed lung is necessary for effective antibiotic prophylaxis of pneumonia. Patients and Methods: The pharmacokinetics/pharmacodynamics (PK/PD) of cefuroxime were compared between the plasma and interstitial fluid (ISF) of collapsed and ventilated lungs in 10 anesthetized pigs, which were ventilated through a double-lumen endotracheal cannula. Cefuroxime (20 mg/kg) was administered in single 30-minute intravenous infusion. Samples of blood and lung microdialysate were collected until six hours post-dose. Ultrafiltration, in vivo retrodialysis, and high-performance liquid chromatography-tandem mass spectrometry were used to determine plasma and ISF concentrations of free drug. The concentrations were examined with non-compartmental analysis and compartmental modeling. Results: The concentration of free cefuroxime in ISF was lower in the non-ventilated lung than the ventilated one, evidenced by a lung penetration factor of 47% versus 63% (p < 0.05), the ratio between maximum concentrations (65%, p < 0.05), and the ratio between the areas under the concentration-time curve (78%, p = 0.12). The time needed to reach a minimum inhibitory concentration (MIC) was 30%-40% longer for a collapsed lung than for a ventilated one. In addition, a delay of 10-40 minutes was observed for lung ISF compared with plasma. The mean residence time values (ISF collapsed lung > ISF ventilated lung > plasma) could explain the absence of practically important differences in the time interval with the concentration of cefuroxime exceeding the MICs of sensitive strains (≤4 mg/L). Conclusion: The concentration of cefuroxime in the ISF of a collapsed porcine lung is lower than in a ventilated one; furthermore, its equilibration with plasma is delayed. Administration of the first cefuroxime dose earlier or at a higher rate may be warranted, as well as dose intensification of the perioperative prophylaxis of pneumonia caused by pathogens with higher MICs.

ABSTRACT

Objectives. Female sex has been generally accepted as a risk factor for short-term mortality and adverse events in surgical myocardial revascularization. However, there have been no data published yet about sex differences in minimally invasive settings. The aim of our study was to analyse short- and long- term outcomes of minimally invasive direct coronary artery bypass grafting (MIDCAB) in terms of sex comparison. Design. We retrospectively analysed the in-hospital data of all patients (n = 384) undergoing MIDCAB at our department in years 2006-2016. Subsequently, the data were enriched by long-term outcomes from national registries. Results. There were 96 women in our group (25%). Females were significantly older (67.1 vs 63.8 years; p < .01) and were more often diabetic (43.8% vs. 31.8%; p < .01). Surgery time was longer in females (160 vs 155 min; p = .02), and also the need for blood transfusion (19.8% vs 10.4%; p = .02) and wound complications (15.6% vs 2.4%; p < .001) were more frequent in women. After multivariate analysis, the wound complications risk (p < .001) and longer surgery times (p < .01) remained associated with sex. All-cause in-hospital mortality (2.1% vs 0.7%; p = .26), long-term mortality (p = .73), and the risk of coronary intervention post-operatively (p = .16) were the same in both sexes. Higher incidence of cardiac cause of death in women was observed from long-term aspect (69.6% vs 38.7%; p = .01). However, after adjustment it lost its significance. Conclusions. Female sex is not connected with higher risk of mortality or other major events in MIDCAB. Wound healing complications remain the leading attribute associated with female sex.

ABSTRACT

BACKGROUND: We evaluated the feasibility and effectiveness of thoracoscopic and a staged surgical and transcatheter ablation technique to treat stand-alone atrial fibrillation (AF). METHODS: . Between 2009 and 2016, a cohort of 65 patients underwent bilateral totally thoracoscopic ablation of symptomatic paroxysmal AF (n=30; 46%), persistent AF (n=18; 28%) or long-standing persistent AF (n=17; 26%) followed by catheter ablation in case of AF recurrence. Surgical box lesion procedure included bilateral pulmonary vein and left atrial posterior wall ablation using irrigated bipolar radiofrequency with documentation of conduction block. RESULTS: There were no intra- or peri-operative ablation-related complications. There was no operative mortality, no myocardial infarction, and no stroke. Skin-to-skin procedure time was 120.5 ± 22.0 min and the postoperative average length of stay was 8.1 ± 3.0 days. At discharge, 60 patients (92%) were in sinus rhythm. Median follow-up time was 866 days (IQR, 612-1185 days). One-year success rate after surgical procedure was 78% (off antiarrhythmic drugs). Eleven patients (17%) underwent catheter re-ablation. Sixty (92%) patients were free of atrial fibrillation after hybrid ablation (on demand) at 1 year follow up after the last ablation. The success at 24-months was achieved in 96% (paroxysmal) and 78% (persistent) patients. At the last follow-up control, 69% patients discontinued oral anticoagulant therapy. CONCLUSIONS: . Combination of mini-invasive surgical and endocardial treatment (two-stage hybrid procedure) is a safe and effective method for the treatment of isolated (lone) AF. This procedure provided good midterm outcomes.
