RESUMO
OBJECTIVE: To analyze the data of the psychological assessment, focusing attention on the quality of life and the psychological status of patients who are listed for heart transplant. METHODS: All heart failure patients listed for heart transplant at the Cardiac Surgery Unit of Bari University, Italy, were evaluated from September to November 2023, by administering the Symptom Checklist-90-R (SCL-90-R) and the Short Form Health Survey 36 (SF-36). RESULTS: Overall, 27 patients were studied. Mean age was 60 years, 88% were males. One third of the patients showed a clinically significant overall mental distress. The symptoms leading to domains such as somatization (55.55%), anxiety (40.74%) and depression (33.33%) were frequently observed. The majority of the population studied (96.30%) showed low levels of perceived physical health status, while 59,62% of them presented levels of perceived physical health status below normal ranges. CONCLUSIONS: Heart transplant candidates show elements of overall mental distress and low quality of life related to physical health status.

Cardiac surgery with cardiopulmonary bypass (CBP) is essential for different cardiac procedures in order to perform surgery with a clear sight field.To safely perform surgery with CPB and preserve brain, kidney, and patient tissue from ischemic damage, cold cardioplegia, and mild to deep hypothermia are induced during the operation.Cryoglobulinemia is a hematological/infective-related disease (in certain cases idiopathic) in which temperature-dependent antibodies tend to aggregate and form emboli in the vascular system causing tissue damage if exposed to low temperature.The patient with cryoglobulinemia (known and unknown) can be at risk of a major ischemic event during CPB and induced hypothermia.This article's aim is to evaluate the present scientific literature in order to understand how, in years, the therapeutic or preventive approach, is evolving, and to analyze and make improvements to the management of a cryoglobulinemic patient who must undergo elective or emergency cardiac surgery.In the last part of our article, we expose our single-center experience during a 32-month-long period of survey.In all cases, our medical team (anesthesiologists, perfusionists, and cardiac surgeons) opted for a normothermic cardiopulmonary bypass to lower the risk of cryoglobulin-associated complications.In our experience, along with therapeutic intervention to lower the cryoglobulin titer, normothermic management of cardiopulmonary bypass is as safe as hypothermic management.Notwithstanding our results, further studies with a larger population are needed to confirm this perioperative management in a cardiac surgery setting.
RESUMO
BACKGROUND: Studies reporting on the outcome of 90-year-old patients undergoing cardiac surgery are scant in literature; and currently, those regarding the implementation of trans-catheter techniques number even fewer. METHODS: We compared patients aged >89 years operated on between 1998 and 2008 at 8 Italian cardiac surgery centers, with patients of the same age operated on between 2009 and 2021. All of the patients were operated on with "open" surgery, with the exclusion of percutaneous valve repair/implantation procedures. RESULTS: The patients of the two groups (group 98-08-127 patients, and group 09-21-101 patients) had comparable preoperative risk factors in terms of the LogEuroSCORE (98-08: 21.3 ± 6.1 vs. 09-21: 20.9 ± 11.1, p = 0.12). There was a considerable difference in the type of surgery (isolated valve, isolated coronary, and combined surgery, 46.5, 38.5, and 15% vs. 52, 13, and 35% in 98-08 and 09-21, respectively, p = 0.01). Analogous operating durations were recorded (cross-clamp time: 98-08: 46 ± 28 min vs. 09-21: 51 ± 28 min, p = 0.06). The number of packed bypasses was lower in 09-21 (1.3 ± 0.6 vs. 2.4 ± 1.2, p = 0.001). In the postoperative period, there was a statistically significant difference in the 30-day survival in favor of the "more recent" patients (98-08: 17 deaths (13.4%) versus 09-21: 6(5.9%); p = 0.001), also confirmed in the subgroups (12.2% vs. 0% in isolated coronary surgery, p < 0.001; and 12.3% vs. 0% in isolated valve surgery, p < 0.001). CONCLUSIONS: Accurate pre-, intra-, and post-operative evaluation/management to reduce biological impacts facilitate significant improvements in the outcomes in nonagenarian patients when compared to the results recorded in previous years.
RESUMO
BACKGROUND: Length measurement of artificial chordae remains a critical step during mitral valve repair (MVr). The aim of this study is to assess the effectiveness of a new length measuring technique. METHODS: All consecutive patients with anterior leaflet prolapse/flail who underwent MVr using the described method between January 2020 and January 2022 at our institution were included in the analysis. Clinical and transesophageal echocardiography data were collected postoperatively and at 1-year follow-up. The primary outcome was freedom from mitral regurgitation (MR). Secondary outcomes were presentation with New York Heart Association (NYHA) class <2 and leaflet coaptation length ≥10 mm. RESULTS: Of 25 patients, 16 (64%) were males. A total of 15 (60%) had isolated anterior leaflet disease, while 10 (40%) had concomitant posterior involvement. Twenty patients with isolated MR (80%) underwent right anterior mini-thoracotomy, while 5 (20%) with associated valvular or coronary disease underwent sternotomy. The median number of chordae implanted was 2 [1-4]. Postrepair intraoperative MR grade was 0 in 23 patients (92%) and 1 in 2 (8%). Thirty-day mortality was 0%. De novo atrial fibrillation was 20%. At follow-up, mortality was 0%. No patients presented with moderate or severe MR. A total of 22 patients (88%) were in NYHA class I, while 3 (12%) in class II. The coaptation length was 11 ± 1 mm. CONCLUSIONS: The short-term outcomes of the described technique are good with adequate leaflet coaptation in all treated patients. Long-term results are needed to assess the stability and durability of this repair technique.

BACKGROUND: Insufflation of carbon dioxide (CO2) into the operative field to prevent cerebral or myocardial damage by air embolism is a well known strategy in open-heart surgery. However, here is no general consensus on the best delivery approach. METHODS: From January 2018 to November 2021, we retrospectively collected data of one hundred consecutive patients undergoing minimally invasive mitral valve repair (MIMVR). Of these, fifty patients were insufflated with continuous CO2 1 min before opening the left atrium and ended after its closure, and fifty patients were insufflated with one shot CO2 10 min before the start of left atrium closure. The primary outcome of the study was the incidence of transient post-operative cognitive disorder, in particular agitation and delirium at discontinuation of anesthesia, mechanical ventilation (MV) duration and intensive care unit (ICU) length of stay. RESULTS: In all patients that received continuous field flooding CO2, correction of ventilation for hypercapnia during cardiopulmonary bypass (CPB) was applied with an increase of mean sweep gas air (2.5 L) and monitoring of VCO2 changes. One patient vs. 9 patients of control group reported agitation at discontinuation of anesthesia (p = 0.022). MV duration was 14 ± 3 h vs. 27 ± 4 h (p = 0.016) and ICU length of stay was 33 ± 4 h vs. 42 ± 5 h (p = 0.029). A significant difference was found in the median number of total micro-emboli recorded from release of cross-clamp until 20 min after end of CPB (154 in the continuous CO2 group vs. 261 in the one-shot CO2 control group; p < 0.001). Total micro-emboli from the first 15 min after the release of cross-clamp was 113 in the continuous CO2 group vs. 310 in the control group (p < 0.001). In the continuous CO2 group, the median number of detectable micro-emboli after CPB fell to zero 9 ± 5 min after CPB vs. 19 ± 3 min in the control group (p = 0.85). CONCLUSION: Continuous field flooding insufflation of CO2 in MIMVR is associated with a lower incidence of micro-emboli and of agitation at discontinuation of anesthesia, along with improved MV duration and ICU length of stay.

BACKGROUND: The hybrid approach has become the most effective treatment option for restoring sinus rhythm and reducing the risk of atrial fibrillation (AF) recurrence. However, several issues remain to be clearly defined, including the appropriate timing of the staged procedure and the most effective strategy. METHODS: Over a 12-year period of activity, we performed 609 AF ablation procedures via a right mini-thoracotomy. From this general population, 60 patients underwent a hybrid procedure with catheter ablation performed at least 4 weeks after the surgical procedure to confirm if effective complete electrical isolation of pulmonary veins was achieved. In 20 patients, the second stage procedure was performed during the same hospitalization due to patient's electrical instability. The results obtained in immediate versus staged patients were compared. RESULTS: All patients were discharged after the first stage procedure in sinus rhythm. The 20 immediate patients had a shorter hospital stay compared with the staged patients, in whom the two hospitalizations resulted in a longer hospital stay (immediate 5.5 ± 1.6 days versus staged 8.7 ± 1.4, P < 0.001). A significantly higher number of immediate patients had an associated ablation of the Bachmann's bundle (n = 16 in the immediate group [80%] versus n = 14 in the staged group [45%]; P = 0.001). After a mean follow-up of 74 months, there was no significant difference in the risk of AF relapse between groups (immediate 1/20 [5%] versus staged 7/40 [17.5%]; P = 0.18). CONCLUSION: The hybrid approach for the treatment of AF was safe and effective in immediate restoring sinus rhythm and in its maintenance at follow-up. Our preliminary results show that both immediate and staged procedures show similar efficacy but this result is strongly influenced by the concomitant ablation of the Bachmann's bundle, which appears to be the most important component of the treatment strategy in order to reduce the risk of recurrent AF.

OBJECTIVES: Little is known about the safety and clinical utility of retrograde autologous priming (RAP) in patients undergoing minimally invasive mitral valve surgery. The study authors hypothesized that RAP would increase the oxygen delivery index (DO2i) while decreasing red blood cell transfusion requirements compared to valve surgery without RAP. DESIGN: The study was an observational analysis. SETTING: A single institutional study. PARTICIPANTS: The authors analyzed data from 500 consecutive patients who underwent minimally invasive isolated mitral valve repair from December 31, 2012, to December 31, 2019. INTERVENTION: RAP was performed in 235 patients (47%) prior to the initiation of cardiopulmonary bypass (CPB). MEASUREMENT AND MAIN RESULTS: A continuous monitoring system was used for DO2 management during CPB. The mean arterial pressure was maintained between 55 and 70 mmHg, and the cardiac index was set at 2.4 L/min/m2, with adjustments in accordance with DO2i. The trigger point for red cell blood transfusion during CPB was hemoglobin <7 g/dL. Baseline hematocrit was lower in the RAP group compared to the no-RAP group (33.4 ± 3.6 v 38.1 ± 4.9, respectively; p < 0.001). Both CPB and cross-clamp times were similar between groups. Hematocrit during CPB was significantly higher in the RAP group compared to the no-RAP group (27.6 ± 2.6 v 25.9 ± 5.1, respectively; p < 0.001). RAP was also associated with significantly higher mean DO2i (292 ± 19.5 v 282.9 ± 35.1 mL/min/m2, respectively; p < 0.001) and fewer red blood cells transfusions during the intraoperative and immediate postoperative periods (p < 0.001). CONCLUSIONS: In a minimally invasive mitral valve context, RAP was safe and associated with better DO2i, higher hematocrit, and fewer intraoperative and postoperative red blood cell transfusions.

INTRODUCTION: Left ventricular assist devices are an established therapy for end-stage heart failure. Follow-up of these patients showed complications, such as thrombosis. Our objective was to evaluate the contribution of echocardiography - in association with HeartWare HVAD online logfiles reviews and lactate dehydrogenase titration - for diagnosis and treatment of thrombosis. METHODS: Seventeen episodes of thrombosis were diagnosed in 8/20 patients with HVAD. Diagnosis was made by trans-thoracic echocardiographic blood flow velocities, logfiles review of power consumption and pump flows, and titration of lactate dehydrogenase. Data were collected at baseline routine control (Group A), during thrombosis (Group B), after thrombolysis (Group C). RESULTS: Thrombolysis was successful in all cases; one patient died of cerebral haemorrhage. Echocardiographic maximal blood flow velocity near the inflow cannula was 598±42 cm/sec (Group B), 379.41±21 cm/sec (Group C), and 378.24±28 cm/sec (Group A) (P<0.00001). In eight (47%) cases, thrombi were visualized in the left ventricle by three-dimensional modality. Logfiles recordings of blood flows were 9.52±0.9 L/min (Group B), 4.02±0.4 L/min (Group C), and 4.04±0.4 L/min (Group A) (P<00001). Power consumption was 5.01±0.7 W (Group B), 3.45±0.2 W (Group C), and 3.46±0.2 W (Group A) (P<0.00001). Lactate dehydrogenase was 756±54 IU (Group B), 234±22 IU (Group A), and 257±36 IU (Group C) (P<0.00001). CONCLUSIONS: Echocardiography of increased maximal velocity near the inflow cannula is a sign of HVAD obstruction. Logfile reviews provide a clear picture of HVAD obstruction. Combination of echocardiographic data and review of logfiles detects signs of left ventricular assist devices thrombosis leading to a successful treatment.

Infective endocarditis is a life-threatening condition and despite advances in antibiotic therapy, about one-third of patients require surgical treatment. The choice of the most appropriate surgical treatment is crucial. The study by Asen Petrov et al. paves the way for a new, safe, simple, and useful Calamari technique for the treatment of aortic valve endocarditis complicated by aortic root abscess (ARA). This technique was initially described in a series of five patients. The most interesting part of the study is that the procedure was effective (only one patient died 30 days after surgery) and fast (mean cardiopulmonary bypass time 90 ± 10.30 min; mean cross-clamp time 73.6 ± 12.12 min). As reported by Leontyev et al., the procedure of choice in ARA is represented by a wide range of procedures ranging from aortic valve replacement with debridement of the abscess to reconstruction of the intervalvular fibrous body and replacement of both the mitral valve and the aortic root. Alternatively, pericardial patch reconstruction is required in approximately one-third of cases. Radicality is key but a fast procedure is very important. In this scenario, the Calamari procedure is very useful, especially for its rapid execution (short cardiopulmonary bypass and cross-clamp time) which is associated with a reduction in mortality. A simple procedure to treat complex diseases. However, this procedure needs to be performed on more patients and its outcomes should be compared in trials with the other available techniques for the treatment of ARA.

BACKGROUND: Report the incidence and results of peri-operative extracorporeal membrane oxygenation (ECMO) and intra-aortic balloon pump (IABP) of patients undergoing mitral valve surgery (MVS) through right mini-thoracotomy (RT) and conventional full sternotomy (FS) for a period of 6 years from eleven tertiary Cardiac Surgery Institutes of GVM Care & Research Italia. METHODS: From January 2016 to November 2021, a total of 5901 consecutive patients underwent MVS through RT and FS. The primary outcome of the study was the mortality and incidence of low cardiac output syndrome (LCOS) treated with intra-aortic balloon pump (IABP) with or without inotropic support and the incidence of Postcardiotomy Cardiogenic Shock (PCS) treated with Veno-arterial (VA) Extracorporeal Membrane Oxygenation (ECMO) on patients undergoing mitral valve surgery (MVS) through right mini-thoracotomy (RT) versus conventional full sternotomy (FS). RESULTS: The mean age was 66 ± 15 years, 3389 patients underwent in RT approach 2512 in FS, 3081 (52%) patients were male and 2.3% had previous cardiac operations. Cardiopulmonary bypass time was 93 min for RT and 81 min for FS and cross clamp time 75 min for RT and 63 min for FS for mitral valve repair. Incidence of perioperative IABP for the treatment of low cardiac output was reported on 99 patients (1.6%), 51 for RT (1.5%), 35% used inotropic support (adrenaline and milrinone) and 48 in FS (1.9), 28% use inotropic support, 21 patients died after IABP (3 RT and 18 FS). Incidence of perioperative VA-ECMO for the PCS treatment was 13 and 4 with IABP, 9 RT (0.2%) and 4 FS approach (0.15%), 12 patients died after VA-ECMO. CONCLUSION: Minimally invasive mitral valve surgery is a safe and reproducible approach associated with low mortality and morbidity. ECMO and IABP incidence for the treatment of PCS was 0.2% and for Low cardiac output syndrome (LCOS) was 1.6% in elective mitral valve surgery is very low. The patients that use the perioperative IABP in minimally invasive mitral valve surgery (MIMVS) trough RT reported a reduced mortality compared to FS in relation to the operative risk and surgical technique. Low incidence of VA-ECMO was found in RT and FS approach, only one patient survived after VA-ECMO after minimally invasive mitral valve surgery.

Primary malignant cardiac tumors represent (PMCTs) a very rare disease with an incidence of 0.009%1 (up to 10% of primary cardiac neoplasms) and are related to a very poor prognosis. The study by Mohamed Rahouma tries to give us information on sex differences in PMCTs, their incidence, behavior, and outcomes. Females were significantly older and had a lower stage of cancer. Males are known to have a more aggressive course and present at an earlier age. Sarcoma is the most common type of PMCTs in both males and females. There was no gender disparity in late mortality and patients who underwent surgery had a better prognosis than those who did not undergo surgery. Significant predictors of late mortality were found to be patients' high comorbidity index, angiosarcoma histology, and Stage III/IV. A challenge for cardiac surgeons is to improve survival in patients with cardiac malignancies, involving a multidisciplinary approach with oncologists, cardiologists, and radiologists. To pave the way for a significant improvement in survival in the future, more advanced sex-specific medical therapies for cancer such as novel chemotherapy agents, targeted immune therapies, genetic engineering need to be standardized to PMCTs and combined with radiological therapies such as gamma-knife and very advanced surgery to effectively treat even very aggressive forms of malignant tumors, with a significant impact on the patient's quality of life and survival.

BACKGROUND AND AIM OF THE STUDY: The debate on the usefulness of the minimally invasive approach in mitral valve surgery is still open. The aim of this study is to describe a single-center case series of all comers undergoing minimally invasive mitral valve reconstruction. METHODS: From 2010 to 2019, all the data recorded in the medical records of 893 consecutive patients undergoing mitral valve reconstruction through a right mini-thoracotomy were retrospectively collected. All patients were contacted by telephone for remote evaluation and integration of echocardiographic information on surgical results. RESULTS: Mean age was 62.2 ± 14.5; 447 (50%) were female and mean log EuroSCORE was 2.5 ± 2.8%. At a mean follow-up of 4.1 ± 2.2 years (median 3.9), a total of 24 deaths (2.68%) were recorded. Twenty-four patients required rehospitalization for cardiac causes, 13 (1.4%) patients had at least moderate mitral insufficiency on follow-up echocardiography and, of these, seven patients underwent reoperation (0.8%). The cumulative hazard showed that 8.3% of patients experienced at least one event at 5 years. NYHA class improved significantly with 874 patients in NYHA class I, 13 in NYHA class II, 6 in NYHA class III, and 0 in NYHA class IV at last follow-up (p < .001 from baseline as reference point). CONCLUSIONS: In a high-volume center, mitral valve surgery using a minimally invasive approach is a feasible treatment option for all-comers and is associated with excellent results that are maintained at clinical and echocardiographic follow-up.

We present a new technique for percutaneous retrieval of a U-kinked displaced Impella catheter. First we used the hooker from the left femoral artery to snare the catheter tip. Both catheter and hooker were pulled down simultaneously from 2 opposite sites until the U-kinking sat astride the aortic bifurcation. Finally the loop was straightened by pulling both catheter and hook. Once unfolded the hook was released, and the catheter was retrieved easily from the right femoral artery. This technique is highly reproducible because of several advantages. It is easy to perform, takes a short time, does not require special devices, and is not expensive.

OBJECTIVES: Female sex is an established risk factor for postoperative complications after heart surgery, but the influence of sex on outcomes after minimally invasive cardiac surgery (MICS) for valvular replacement/repair remains controversial. We examined whether the role of sex as a risk factor varies by surgical approach [MICS vs conventional sternotomy (ST)] and further assessed outcomes among female patients including in-hospital mortality and postoperative complications by surgical approach. METHODS: We analysed data from a multicentre registry for patients who underwent isolated aortic valve and mitral surgery with MICS or ST. The primary outcome was in-hospital mortality. Propensity score matching was used to minimize between-group differences. RESULTS: Among the 15 155 patients included in the study, 7674 underwent MICS (50.6%). Female sex was equally distributed in the MICS and ST groups (47.3% vs 47.6%, respectively). Risk for surgery was higher in the ST group than in the MICS group {EuroSCORE II: 4.0 [standard deviation (SD): 6.8] vs 3.7 [SD: 6.4]; P = 0.005}, including among female patients only [ST vs MICS 4.6 (SD: 6.9) vs 4.2 (SD: 6.3); P = 0.04]. Mortality did not significantly vary by procedure among women [MICS vs ST, 2.4% vs 2.8%; hazard ratio 1.09, 95% confidence interval 0.71-1.73; P (surgical approach × sex) = 0.51]. The results also did not vary after adjusting for confounders. CONCLUSIONS: Female sex was associated with higher mortality in patients undergoing valve surgery, regardless of surgical approach. In female patients, MICS did not provide any benefits over ST in terms of in-hospital deaths or postoperative complications. SUBJECT COLLECTION: 117, 125.

BACKGROUND: Catheter-based or surgical procedures in patients with long-standing persistent atrial fibrillation (LSPAF) remain a challenge. As a result, different approaches including hybrid (surgical and endocardial) ablation have been developed. Bachmann's bundle (BB) is a mainly epicardial structure capable of sustaining arrhythmic reentry that could be involved in the development and perpetuation of atrial fibrillation. We investigated the efficacy and safety of an adjunctive BB ablation in LSPAF patients undergoing hybrid ablation. METHODS: In a two-arm non-randomized study, consecutive LSPAF patients undergoing epicardial isolation of pulmonary veins with left atrial posterior wall (box lesion) with (n = 30, BB group) and without additional BB ablation (n = 30, CONV group) were enrolled in the study. All patients underwent an endocardial procedure within 6 weeks post-surgery to assess for potential lesion gaps and additional atrial substrate modification. The primary endpoint was freedom from AF through 12 months of follow-up. RESULTS: The two-staged hybrid ablation was successfully completed in all patients. One-year freedom from atrial arrhythmias recurrence rates was 96.6% in the BB group vs 76.6% in the CONV group (p = 0.025). At procedure completion, 30 (100%) and 17 (56%) patients had a spontaneous cardioversion in BB and CONV group, respectively (p < 0.001). No significant differences in quality of life or complication rates were observed. CONCLUSIONS: This initial experience shows, for the first time, that adjunctive BB ablation in the setting of hybrid ablation for LSPAF is a feasible and effective approach in increasing maintenance of sinus rhythm without increasing complication rates.

BACKGROUND: Patients with coronary artery disease and concomitant heart failure (left ventricular ejection fraction < 35%) requiring myocardial revascularization are at risk of poor long-term prognosis and higher mortality. The benefits of minimally invasive extracorporeal circulation (MiECC), particularly in end-stage coronary artery disease patients undergoing myocardial revascularization, have not been completely described. MATERIALS AND METHODS: In this single-centre control study, 60 end-stage coronary artery disease patients undergoing isolated coronary artery bypass grafting (CABG) were included. Patients were divided into two groups of 30 patients each undergoing CABG using MiECC or conventional extracorporeal circulation (cECC). RESULTS: In the MiECC group, oxygen delivery index (DO2i) was 305 mL/min/m2 in relation to indexed oxygen extraction ratio (O2ERi) 21.5%, whereas in the cECC group DO2i was 288 mL/min/m2 in relation to O2ERi 25.6% (p = 0.037). Lactate levels > 3 mmol/L were reported in 7 MiECC patients vs 20 cECC patients (p = 0.038), with blood glucose peak. Mean nadir hemoglobin values during cardiopulmonary bypass (CPB) were 9.7 g/dL in the MiECC group vs 7.8 g/dL in the cECC group (p = 0.044). Cardiac index during CPB was 2.4 L/min/m2 in both groups. Red blood cell units administered were 8 vs 21 units in the MiECC vs cECC group (p = 0.022). A glycemic peak was recorded in 7 patients of the MiECC group and in 20 patients of the cECC group (p = 0.037). CONCLUSION: In end-stage coronary artery disease, the MiECC technique was associated with a higher DO2i compared to cECC. MiECC patients showed a significant reduction in red blood cell unit administration and peak intraoperative lactate levels, which correlated with better postoperative outcome.

Infective endocarditis represents a surgical challenge associated with perioperative mortality. The aim of this study is to evaluate the predictors of operative mortality and long-term outcomes in high-risk patients. We retrospectively analyzed 123 patients operated on for infective endocarditis from January 2011 to December 2020. Logistic regression model was used to identify prognostic factors of in-hospital mortality. Long term follow-up was made to asses late prognosis. Preoperative renal failure, an elevation EuroSCORE II and prior aortic valve re-replacement were found to be preoperative risk factors significantly associated with mortality. In-hospital mortality was 27% in patients who had previously undergone aortic valve replacement (n = 4 out of 15 operated, p = 0.01). Patients who were operated on during the active phase of infective endocarditis showed a higher mortality rate than those operated on after the acute phase (16% vs. 0%; p = 0.02). The type of prosthesis used (biological or mechanical) was not associated with mortality, whereas cross-clamp time significantly correlated with mortality (mean cross-clamp time 135 ± 65 min in dead patients vs. 76 ± 32 min in surviving patients; p = 0.0005). Mean follow up was 57.94 ± 30.9 months. Twelve patients died (11.65%). Among the twelve mortalities, five were adjudicated to cardiac causes and seven were non-cardiac (two cancers, one traumatic accident, one cerebral hemorrhage, two bronchopneumonia, one peritonitis). Overall survival probability (freedom from death, all causes) at 3, 5, 7 and 8 years was 98.9% (95% CI 97-100%), 96% (95% CI 92-100%), 85.9% (95% CI 76-97%), and 74% (95% CI 60-91%) respectively. Our study demonstrates that an early surgical approach may represent a valuable treatment option for high-risk patients with infective endocarditis, also in case of prosthetic valve endocarditis. Although several risk factors are associated with higher mortality, no patient subset is inoperable. These findings can be helpful to inform decision-making in heart team discussion.

BACKGROUND: This study was conducted to compare the outcomes of prosthetic ring versus autologous pericardial strip for the treatment of functional tricuspid regurgitation during left-sided valve surgery by minimally invasive approach. METHODS: From January 2008 and July 2016, autologous pericardial strip (group P-TAP) was used in 109 patients, and prosthetic ring (group R-TAP) in 115 patients. The primary outcomes were long-term overall survival, development of patch degeneration, and significant tricuspid regurgitation recurrence. The second outcome was the assessment of right ventricular functional parameters. RESULTS: Operative mortality was 1 case (0.9%) in the R-TAP group. At the time of hospital discharge only one patient (0.9%) in the R-TAP group had grade III+ tricuspid regurgitation, and none had grade IV+. Mean follow-up was 94.1 ± 24.5 months. Mild and moderate tricuspid regurgitation recurrence was 3.7% and 4.5% (P-TAP vs. R-TAP groups, p = 0.99). Severe regurgitation was observed in 1.8% of cases only in the R-TAP group (p = 0.49). There were no reoperations. Late mortality was 3.7% and 5.4% (P-TAP vs. R-TAP groups, p = 0.75). Freedom from death, all causes, were comparable among groups (log-rank p = 0.45). There were no statistically significant differences between two groups in TAPSE, left ventricular end-diastolic diameter, left ventricular ejection fraction, and left atrial diameter. CONCLUSIONS: Tricuspid annuloplasty using an autologous pericardial strip in patients undergoing minimally invasive surgery is associated to similar long results (survival, late tricuspid regurgitation, and functional echocardiographic parameters) than annuloplasty with a prosthetic ring. In particular, the pericardial strip over time does not develop any degeneration or retraction.
