RESUMO
BACKGROUND: Severe tricuspid regurgitation (TR) adversely affects long-term survival; however, isolated tricuspid valve (TV) surgery has been rarely performed due to high operative mortality. In addition, the previous literature included heterogeneous TR etiologies. Therefore, we aimed to elucidate early and long-term outcomes of isolated TV surgery for functional TR. METHODS: An electronic search was performed to identify all relevant studies. Baseline characteristics, perioperative variables, and clinical outcomes were extracted and pooled for meta-analysis. RESULTS: This meta-analysis included seven studies. Pooled analyses showed that 68% (35, 89) of patients had preoperative atrial fibrillation or flutter, and 58% (11, 94) had a history of left-sided valve surgery. Seventy-three percent (65, 80) of patients had at least one physical exam finding of right-sided heart failure, and 57% (44, 69) were in New York Heart Association class III or IV. TV replacement was more common than repair. In TV replacement, bioprosthetic valve (39%, 13, 74) was more common than mechanical prosthesis (22%, 18, 26). The early mortality rate was 7%. Twenty percent of patients required a permanent pacemaker postoperatively. The overall 1- and 5-year survival rates were 84.5 and 69.1%, respectively. CONCLUSION: More than half of the patients who underwent isolated TV surgery for functional TR had undergone left-sided valve surgery and had significant heart failure symptoms at the time of surgery. Further studies on the surgical indication for concomitant TV surgery at the time of left-sided valve surgery and the appropriate timing of surgery for isolated functional TR are needed to improve survival.
RESUMO
BACKGROUND: While barbed sutures have been extensively utilized in other disciplines, they have not been widely adopted in cardiac surgery. The lack of safety and feasibility data has limited its use within the field. To aide in the further understanding of how cardiac surgeons can use barbed sutures, we sought to develop a high-pressure in vitro simulation model. We compared knotless barbed sutures in a highly pressurized anastomosis to conventional sutures. METHODS: Ten specimens in total were utilized in prosthesis anastomosis, using 34 mm Gelweave Plexus (Terumo Aortic, Sunrise, FL 33325, USA) and 34 mm Hemabridge (Intergard Woven Hemabridge, Getinge, Göteborg, Sweden). Five models of size 3-0 barbed suture anastomoses using non-absorbable, barbed, self-retaining, monofilament polypropylene sutures (Filbloc® 3-0, Assut Europe, Rome, Italy) were compared against five conventional anastomoses using size 4-0 polypropylene monofilament (Ethicon, USA). The systems were connected using a novel-designed extracorporeal circulation system. Pressure was rapidly increased in the specimen to a mean pressure of 300-350 mmHg, running then for a minimum of 48 hours to assess anastomosis strength and endurance. RESULTS: No anastomotic dehiscence or rupture was recorded. Complex, angular anastomosis required extra stitch leakage sutures in both conventional and barbed suture specimens. CONCLUSION: Using knotless barbed sutures with an additional self-locking maneuver for prosthesis-prosthesis anastomosis in cardiac surgery is feasible in an in vitro model under long term, high-mean pressure when compared to conventional sutures. In vivo trials should be performed to further validate the in vitro findings.

INTRODUCTION: The robotic platform reduces the invasiveness of cardiac surgical procedures, thus facilitating earlier discharge in select patients. We sought to evaluate the characteristics, perioperative management, and early outcomes of patients who underwent postoperative day 1 or 2 (POD1-2) discharge after robotic cardiac surgery at our institution. METHODS: Retrospective review of 169 patients who underwent robotic cardiac surgery at our facility between 2019 and 2021 identified 57 patients discharged early on POD1 (n = 19) or POD2 (n = 38) and 112 patients who underwent standard discharge (POD3 or later). Relevant data were extracted and compared. RESULTS: In the early discharge group, median patient age was 62 [IQR: 55, 66] (IQR = interquartile range) years, and 70.2% (40/57) were male. Median Society of Thoracic Surgeons predictive risk of mortality score was 0.36 [IQR: 0.25, 0.56] %. The most common procedures performed were mitral valve repair [66.6%, (38/57)], atrial mass resection [10.5% (6/57)], and coronary artery bypass grafting [10.5% (6/57)]. The only significant differences between the POD1 and POD2 groups were shorter operative time, higher rate of in-operating room extubation, and shorter ICU length of stay in the POD1 group. Lower in-hospital morbidity and comparable 30-day mortality and readmission rates were observed between the early and standard discharge groups. CONCLUSIONS: POD1-2 discharge after various robotic cardiac operations afforded lower morbidity and similar 30-day readmission and mortality rates compared to discharge on POD3 or later. Our findings support the feasibility of POD1-2 discharge after robotic cardiac surgery for patients with low preoperative risk, an uncomplicated postoperative course, and appropriate postoperative management protocols.

BACKGROUND: The optimal power and duration settings for radiofrequency (RF) atrial fibrillation (AF) ablation to improve efficacy and safety is unclear. We compared low-power long-duration (LPLD), high-power short-duration (HPSD), and very HPSD (vHPSD) RF settings for AF ablation. METHODS: This network meta-analysis (NMA) was structured according to the Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. Medline, Scopus and Cochrane Central Register of Controlled Trials were systematically searched to identify relevant studies. Observational and randomized studies were included. Eligible studies compared outcomes in AF patients who underwent first-time RF ablation with the following settings: vHPSD (70-90 W, 3-10 s), HPSD (45-60 W, 5-10 s), or LPLD (20-40 W, 20-60 s). RESULTS: Thirty-six studies comprising 10,375 patients were included (33% female). Frequentist NMA showed LPLD tended toward a lower odds of freedom from arrhythmia (FFA) versus HPSD (OR 0.93, 95% CI 0.86-1.00). There was no difference in FFA between vHPSD versus HPSD. Splitwise interval estimates showed a lower odds of FFA in LPLD versus vHPSD on direct (OR 0.78, 95% CI 0.65-0.93) and network estimates (OR 0.85, 95% CI 0.73-0.98). Frequentist NMA showed less total procedural (TP) time with HPSD versus LPLD (generic variance 1.06, 95% CI 0.83 to 1.29) and no difference between HPSD versus vHPSD. CONCLUSION: This NMA shows improved procedural times in HPSD and vHPSD versus LPLD. Although HPSD tended toward improved odds of FFA compared to LPLD, the overall result was not statistically significant. The odds of FFA in LPLD was lower versus vHPSD on direct and network estimates on splitwise interval analysis. Large prospective head-to-head randomized trials are needed to validate HPSD and vHPSD settings.

BACKGROUND: Microaxial circulatory support devices have been used to support patients treated with percutaneous coronary intervention (PCI) for acute myocardial infarction complicated by cardiogenic shock (AMICS). The purpose of this systematic review and meta-analysis was to pool and analyze the existing evidence on the baseline characteristics, periprocedural data, and outcomes of microaxial support before and after PCI in AMICS. METHODS: An electronic database search was performed to identify all cohort studies on Impella and PCI for cardiogenic shock in the English language. A total of five articles comprising 543 patients were included. These patients received microaxial support either before (pre-PCI) or after (post-PCI) undergoing PCI. Comparative analyses were done between both groups. RESULTS: The mean patient age was 66 years [95% Confidence Interval (58-74)], and 22% (89/396) of patients were female. ST-elevation myocardial infarctions (MI) comprised 64% (44-80) of MIs and 50% (44-56) of MIs involved the left anterior descending artery. The mean number of diseased vessels was 2.21 (1.62-2.80). The mean left ventricular ejection fraction was 31% (23.4-38.6). The mean arterial pressure was 66.3 mm Hg (54.1-78.5). Mean serum lactate [6.1 mmol/L (3.3-8.9)] and serum creatinine [1.4 mg/dl (1.0-1.7)] were similar between groups. 30-day mortality was lower in the pre-PCI group [41% (34%-49%)] compared to the post-PCI group [61% (42%-77%), p < 0.01]. Pooled Kaplan-Meier analysis showed better early survival in the pre-PCI group (p < 0.001). CONCLUSION: Patients presenting with AMICS were similar at baseline in both pre-PCI and post-PCI groups. Nevertheless, pre-PCI group showed better early survival compared to post-PCI group.

BACKGROUND: Several factors affect heart transplant (HTx) and lung transplant (LTx) program outcomes. Variabilities in institutional and community characteristics have been shown to influence survival. At present, half of HTx centers in the United States do not possess a concomitant LTx program. This study sought to better understand the characteristics of HTx with and without LTx programs. METHODS: Nationwide transplant data were collected from the Scientific Registry of Transplant Recipients (SRTR) in August 2020. SRTR star rating ranges from tier 1 (lowest) to tier 5 (highest). HTx volumes and SRTR star ratings for survival were compared between the centers with heart-only (H0) programs and the centers with heart-lung (HL) programs. RESULTS: SRTR star ratings were available for 117 transplant centers with one or more HTx reported. The median number of HTx performed over 1 year was 16 (interquartile range [IQR]: 2-29). The number of HL centers (n = 67, 57.3%) were comparable to H0 centers (n = 50, 42.7%; p = 0.14). The HTx volume at the HL centers (28 [IQR: 17-41]) exceeded the HTx volume at the H0 centers (13 [IQR: 9-23]; p < 0.01), but were comparable to the LTx volume at the HL centers (31 [IQR: 16-46]; p = 0.25). The median HTx one-year survival rating was 3 (IQR: 2-4) at both the H0 and HL centers (p = 0.85). The HTx and LTx volumes were positively associated with the respective 1-year survivals (p < 0.01). CONCLUSION: While the presence of an LTx program is not directly associated with HTx survival, it has a positive association with the HTx volume. The HTx and LTx volumes are positively associated with the 1-year survival.
RESUMO
INTRODUCTION: Minimally invasive approaches to mitral valve surgery are being performed with increasing frequency; however, many of these procedures still involve rib spreading and large incisions. The heterogeneity of self-reported "minimally invasive" approaches limits analysis of outcomes. This review aims to formally define totally endoscopic mitral valve surgery (TEMVS) and assess outcomes. MATERIALS AND METHODS: A comprehensive literature search in Pub-Med, Cochrane Library, and EMBASE was used to find studies reporting outcomes on totally endoscopic mitral valve surgery. "Totally endoscopic" was defined as incisions less than 3cm and the avoidance of rib spreading. The primary outcome was 30-day mortality and secondary endpoints included postoperative myocardial infarction (MI), stroke, early reoperation, wound infection, renal failure, and prolonged ventilation. Perioperative patient characteristics were also recorded and analyzed. RESULTS: Thirty-three studies (6031 patients) were included in our meta-analysis. The 30-day mortality rate was 0.33%, p=0.88. The most frequent complications were early reoperation (2.12%, p=0.44) and prolonged ventilation (1.46% p=<0.01). Rates of MI, stroke, and renal failure were each less than 1%. Patient characteristics including age, body mass index (BMI), and ejection fractions were also analyzed. CONCLUSIONS: We propose a formal definition of TEMVS, which is performed through incisions less than 3cm and without rib spreading. Thirty-day mortality and other adverse sequelae of TEMVS are uncommon.
RESUMO
PURPOSE: Heparin-induced thrombocytopenia (HIT) presents a unique challenge in patients requiring orthotopic heart transplantation (OHT). We sought to pool the existing evidence in a systematic review. METHODS: Electronic search was performed to identify all relevant studies on OHT in patients with HIT. Patient-level data for 33 patients from 21 studies were extracted for statistical analysis. RESULTS: Median patient age was 51 [IQR 41, 55] years, with 75.8% (25/33) males. All patients had a clinical diagnosis of HIT, and anti-PF4/Heparin antibodies were positive in 87.9% (29/33). Median lowest reported platelet count was 46 × 109 /L [27.2, 73.5]. Intraoperatively, 61% (20/33) of patients were given unfractionated heparin (UFH), while 39% (13/33) were given alternative anticoagulants. The alternative agent subgroup required more antifibrinolytics [54% (7/13) vs 10% (2/20), P = .02] and clotting factors [69.2% (9/13) vs 15.0% (3/20), P < .01]. Perioperative thrombosis occurred more [53.8% (7/13) vs 0% (0/20, P < .01) in alternate agent subgroup. More patients in the alternate agent subgroup required post-operative transfusions [54% (7/13) vs 0% (0/20), P < .01]. Thirty-day mortality of 15.2% (5/33) was comparable between the subgroups. CONCLUSION: Heparin use during OHT may be associated with less adverse effects compared to use of other anticoagulants with no difference in 30-day mortality.

Treatment of Staphylococcus aureus infections is complicated by the development of antibiotic tolerance, a consequence of the ability of S. aureus to enter into a nongrowing, dormant state in which the organisms are referred to as persisters. We report that the clinically approved anthelmintic agent bithionol kills methicillin-resistant S. aureus (MRSA) persister cells, which correlates with its ability to disrupt the integrity of Gram-positive bacterial membranes. Critically, bithionol exhibits significant selectivity for bacterial compared with mammalian cell membranes. All-atom molecular dynamics (MD) simulations demonstrate that the selectivity of bithionol for bacterial membranes correlates with its ability to penetrate and embed in bacterial-mimic lipid bilayers, but not in cholesterol-rich mammalian-mimic lipid bilayers. In addition to causing rapid membrane permeabilization, the insertion of bithionol increases membrane fluidity. By using bithionol and nTZDpa (another membrane-active antimicrobial agent), as well as analogs of these compounds, we show that the activity of membrane-active compounds against MRSA persisters positively correlates with their ability to increase membrane fluidity, thereby establishing an accurate biophysical indicator for estimating antipersister potency. Finally, we demonstrate that, in combination with gentamicin, bithionol effectively reduces bacterial burdens in a mouse model of chronic deep-seated MRSA infection. This work highlights the potential repurposing of bithionol as an antipersister therapeutic agent.

BACKGROUND: Percutaneous axillary artery cannulation for cardiopulmonary bypass (CPB) offers a novel alternate approach to mechanical circulatory support for patients with contraindications to femoral perfusion. To our knowledge, this has not yet been reported in minimally invasive cardiac surgery (MICS). AIM: We aim to highlight our experience using percutaneous axillary artery cannulation to safely facilitate CPB for minimally invasive cardiac surgery MICS. METHODS: Four patients who underwent robotic cardiac surgery utilizing the axillary artery for percutaneous cannulation between November 2019 and August 2021 at a single center were identified and included in the analysis. Preoperative, intraoperative, and postoperative data were collected and analyzed to support this case series. RESULTS: There were no perioperative hematomas, brachial plexus injuries, or neurovascular injuries. Within 30-days postoperatively there was no mortality, vessel injury, stroke, new onset atrial fibrillation, or other life-threatening bleeding. CONCLUSION: Percutaneous cannulation of the axillary artery is a novel and promising CPB modality for robotic cardiac surgery in patients with extensive peripheral and aortic atherosclerotic disease.

OBJECTIVE: Prior studies have demonstrated robotic excision of cardiac tumors as a safe and effective treatment option. The procedure is performed with five incisions: three robotic arm ports, one atrial retractor port, and one working port. We report our unique initial experience in robotic tumor removal. To our knowledge, this is one of the first reports demonstrating cardiac myxoma and fibroelastoma removal with use of exclusively 8-mm ports. METHODS: All data for robotic cardiac tumor resection at our institution from June 2019 to December 2021 were retrospectively collected; 18 cases were included, including 13 cardiac myxomas and five fibroelastomas. Baseline demographics, intraoperative characteristics, and surgical outcomes were recorded. Descriptive statistics were calculated; continuous variables were reported as median [interquartile range], and categorical variables were reported as percentages. RESULTS: Median patient age was 64 [55, 70] years old. The cohort consisted of primarily female (67%) and white (83%) patients. Median body mass index was 26.3 [23.0, 31.5] kg/m2 . 11% of patients were current tobacco users and 50% had hypertension. All patients underwent myxoma or fibroelastoma removal with the use of five 8-mm robotic ports. Each patient underwent percutaneous cannulation via the femoral arteries. Aortic occlusion was achieved via an endoaortic balloon (67%) or transthoracic cross-clamp (33%). Cross-clamp time was 30 [26, 41] minutes. Concomitant procedures performed during myxoma removal included patent foramen ovale closure (28%), mitral valve repair (8%), left atrial appendage closure (8%), Cox-maze procedure (6%), and coronary artery bypass grafting (6%). All cardiac tumors were packaged with use of the endo-bag and subsequently removed through the working port. Maximal myxoma and fibroelastoma diameters were 2.5 [1.7, 3.5] and 0.6 [0.4, 0.7] cm, respectively. Procedural cardiopulmonary bypass time was 77 [65, 84] minutes. No intraoperative mortality, reoperation for bleeding, or postoperative cardiac issues were recorded. One in-hospital mortality occurred as the result of a thrombotic event in the context of a hypercoagulable state unrelated to the patient's operation. No other mortalities were observed at 30 days. Hospital length of stay was 4.5 [3.0, 7.8] days. CONCLUSIONS: In our study, the robotic platform facilitated safe and effective cardiac tumor excision. Our results highlight the efficacy of 8-mm port sizing and the concurrent use of other minimally invasive techniques, including percutaneous cannulation, in this patient population. In general, patients prefer the least invasive treatment option available. Our findings emphasize the importance of training cardiac surgeons to perform robotic procedures using the least invasive means possible to provide patients with various options for their treatment.

In the present report, we describes a case of surgical resection of an isolated superficial temporal artery aneurysm without underlying systemic pathology. Although aneurysms of this sort most commonly occur in the setting of recent trauma, this case demonstrates an uncommon presentation. We hope to further contribute to the literature regarding this condition.
RESUMO
A 61-year-old male presented via referral for mitral regurgitation and was deemed an appropriate robotic surgery candidate for complex mitral valve repair with the maze procedure and patent foramen ovale and left atrial appendage closures, using all percutaneous cannulation. We report upon the first case in the literature that describes the use of only 4 robotic ports, with no working port used.

Endoaortic balloon occlusion (EABO) and transthoracic cross-clamping have been shown to have comparable safety profiles for aortic occlusion in minimally invasive mitral valve surgery (MIMVS). However, few studies have focused exclusively on the totally endoscopic robotic approach. We sought to compare outcomes for patients undergoing totally endoscopic robotic mitral valve surgery with aortic occlusion via EABO and transthoracic clamping after a period where EABO was unavailable required us to use the transthoracic clamp. Retrospective review identified 113 patients who underwent robotic mitral valve surgery at our facility between 2019 and 2021 with EABO (n = 71) or transthoracic clamping (n = 42). Relevant data were extracted and compared. Preoperative characteristics were similar other than a higher rate of coronary artery disease [EABO: 69.0% (49/71) vs clamp: 45.2% (19/42), p = .02] and chronic lung disease [EABO: 38.0% (27/71) vs clamp: 9.5% (4/42), p < .01] in the EABO group. Median percutaneous cardiopulmonary bypass time, operative time, and cross-clamp time were comparable. Similar rates of postoperative bleeding complications were observed, and no aortic complications were observed. One patient in each group underwent conversion to an open approach. 30-day mortality and readmission rates were comparable. EABO and transthoracic clamp were associated with similar bleeding and aortic outcomes, and mortality and readmission rates were comparable at thirty days postoperatively. Our findings support the comparable safety of the two techniques, which is well documented in studies encompassing all MIMVS techniques, within the specific context of the totally endoscopic robotic approach.

BACKGROUND: The University of Pennsylvania classification system (Penn class) of acute type A aortic dissection (aTAAD) is used to evaluate the impact of malperfusion on surgical outcomes. The purpose of this analysis was to determine the validity of Penn class in a larger and more contemporary cohort and to compare its performance with other classification systems. METHODS: This was a retrospective study of patients who underwent aTAAD repair at our institution from 1993 to 2020. Patients were assigned to Penn class on the basis of burden of preoperative malperfusion syndrome. The association of Penn class and 30-day mortality was evaluated by multivariable regression. The discriminatory ability of Penn class for mortality was determined by a bootstrapped C statistic. RESULTS: There were 1192 patients, of whom 50% were assigned to Penn class A (no ischemia), 21% (253/1192) to class B (local ischemia), 14% (171/1192) to class C (generalized ischemia), and 14% (167/1192) to class B-C (combined ischemia). The incidence of mortality rose significantly with increasing Penn class from 5% (31/601) in class A to 35% (59/167) in class B-C (P < .001). After adjustment, 30-day mortality increased significantly with class B (odds ratio [OR], 2.43; 95% CI, 1.38-4.27), class C (OR, 3.39; 95% CI, 1.90-6.03), and class B-C (OR, 13.08; 95% CI, 7.90-22.15) compared with class A. The C statistic was 0.77 (95% CI, 0.72-0.80) and was significantly higher than for models featuring alternative classification systems (P < .05). CONCLUSIONS: Penn class provides excellent discrimination for 30-day mortality after repair of aTAAD.

OBJECTIVE: Barbed nonabsorbable sutures have been widely adopted for tissue closure in noncardiac robotic surgery to improve intraoperative efficiency. Here, we examine the profile in robotic mitral valve repair (rMVR), which utilized barbed nonabsorbable sutures. To our knowledge, this is the first report to describe clinical outcomes for rMVR with barbed nonabsorbable sutures. METHODS: A retrospective review identified 90 patients who underwent rMVR using barbed nonabsorbable sutures at our center between 2019 and 2021. The primary outcome measure was dehiscence, while other relevant outcomes included 30-day readmission and 30-day mortality. RESULTS: In addition to fixation of the mitral annuloplasty band, barbed nonabsorbable sutures were employed commonly in concomitant pericardiectomy closure (100.0%, 90 of 90), atriotomy closure (100.0%, 90 of 90), and left atrial appendage closure (if eligible; 98.8%, 83 of 84). One patient who underwent mitral valve annuloplasty using only barbed nonabsorbable suture required reoperation for annuloplasty ring dehiscence. Immediate postoperative ring dehiscence was not observed in any patients after the routine reinforcement of barbed nonabsorbable sutures with everting pledgeted polyester sutures, and no additional patients required reoperation for suture-related complications. Clinical signs of dehiscence were not observed after pericardiectomy, atriotomy, or left atrial appendage closure with barbed nonabsorbable sutures. The 30-day readmission rate was 3.3% (3 of 90), and 30-day mortality was 0% (0 of 90). CONCLUSIONS: These data suggest the initial feasibility of barbed nonabsorbable sutures in robotic cardiac surgery, specifically within rMVR. Further research is necessary to explore the long-term safety and efficacy profile of such approach.

OBJECTIVES: The purpose of this study was to describe levels of adherence to guideline-based medical management in patients with aortic aneurysms, using an analogous population with coronary artery disease as a comparator. Adherence among those with aortic aneurysms has never been studied. METHODS: Adult patients with an aortic aneurysm or coronary artery disease diagnosed between 2004 and 2018 in the Optum Clinformatics deidentified Datamart were queried. Aneurysms were subclassified as thoracic, abdominal, or both. Receipt of an antihypertensive or antihyperlipidemic was determined through pharmacy claims. Adherence was determined as receipt of the indicated pharmacologic(s) after a diagnosis of aneurysm or coronary artery disease. Adherence was compared between those with aneurysms and coronary disease using univariable logistic regression. RESULTS: After exclusions, 194,144 patients with an aortic aneurysm and 3,946,782 with coronary artery disease were identified. Overall adherence was low (45.0%) and differed significantly by aneurysm subtype: highest in isolated thoracic (45.9%) and lowest in isolated abdominal aneurysms (42.6%). Adherence levels declined significantly after 1 year by about 15% in each aneurysm subtype. All subtypes of aneurysm had a significantly lower odds of adherence compared to those with coronary disease with odds ranging from 0.61 in those with isolated abdominal aneurysms to 0.80 with isolated thoracic aneurysms. CONCLUSIONS: Adherence among those with aortic aneurysms is very low, differs by subtype, and declines with time. Levels of adherence in those with aortic aneurysms is significantly lower compared to those with coronary artery disease. This should prove a reasonable target for implementation initiatives.
