RESUMEN
OBJECTIVES: Barlow's disease is a specific sub-form of mitral valve (MV) disease, characterized by diffuse excessive tissue and multi segment prolapse. The anterolateral mini-thoracotomy represents the standard access for MV regurgitation in many centres. It still remains unclear which surgical technique provides the best results. Therefore, the aim of this study was to compare operative safety and mid-term outcomes after (i) isolated annuloplasty, (ii) use of additional artificial chordae or (iii) leaflet resection in patients suffering from Barlow's disease undergoing minimally invasive MV repair. METHODS: A consecutive series of patients suffering from Barlow's disease undergoing minimally invasive MV surgery between 2001 and 2020 were analysed (n = 246). Patients were grouped and analysed according to the used surgical technique. The primary outcome was a modified Mitral Valve Academic Research Consortium combined end-point of mortality, reoperation due to repair failure or reoccurrence of severe mitral regurgitation within 5 years. The secondary outcome included operative success and safety up to 30 days. RESULTS: No significant difference was found between the 3 surgical techniques with regard to operative safety (P = 0.774). The primary outcome did not differ between groups (P = 0.244). Operative success was achieved in 93.5% and was lowest in the isolated annuloplasty group (77.1%). Conversion to MV replacement was increased in patients undergoing isolated annuloplasty (P < 0.001). CONCLUSIONS: Isolated annuloplasty, use of additional artificial chordae and leaflet resection represent feasible techniques in Barlow patients undergoing minimally invasive MV surgery with comparable 5-year results. In view of the increased conversion rate in the annuloplasty group, the pathology should not be oversimplified.

OBJECTIVES: Minimally invasive mitral valve surgery (MIMVS) has evolved over the last 2 decades. The aim of the study was to identify the impact of era and technical improvements on perioperative outcome after MIMVS. METHODS: A tota of 1000 patients (mean age: 60.8 ± 12.7 years, 60.3% male) underwent video-assisted or totally endoscopic MIMVS between 2001 and 2020 in a single institution. Three technical modalities were introduced during the observed period: (i) 3D visualization, (ii) use of premeasured artificial chordae (PTFE loops) and (iii) preoperative CT scans. Comparisons were made before and after the introduction of technical improvements. RESULTS: A total of 741 patients underwent isolated mitral valve (MV) procedure, whereas 259 received concomitant procedures. These consisted of tricuspid valve repair (208), left atrium ablation (145) and persistent foramen ovale or atrial septum defect (ASD) closure (172). The aetiology was degenerative in 738 (73.8%) patients and functional in 101 patients (10.1%). A total of 900 patients received MV repair (90%), and 100 patients (10%) underwent MV replacement. Perioperative survival was 99.1%, and periprocedural success 93.5% with a periprocedural safety of 96.3%. Improvement in periprocedural safety attributed to the lower rates of postoperative low output (P = 0.025) and less reoperations for bleeding (P < 0.001). 3D visualization improved cross-clamp (P = 0.001) but not cardiopulmonary bypass times. The use of loops and preoperative CT scan both had no impact on periprocedural success or safety but improved cardiopulmonary bypass and cross-clamp times (both P < 0.001). CONCLUSIONS: Increased surgical experience improves safety in MIMVS. Technical improvements are related to increased operative success and decreased operative times in patients undergoing MIMVS.

OBJECTIVES: Surgical treatment of destructive infective endocarditis consists of extensive debridement followed by root repair or replacement. However, it remains unknown whether 1 is superior to the other. We aimed to analyse whether long-term results were better after root repair or replacement in patients with root endocarditis. METHODS: A total of 148 consecutive patients with root endocarditis treated with surgery from 1997 to 2020 at our department were included. Patients were divided into 2 groups: aortic root repair (n = 85) or root replacement using xenografts or homografts (n = 63). RESULTS: Patients receiving aortic root repair showed significantly better long-term survival compared to patients receiving aortic root replacement (log-rank: P = 0.037). There was no difference in terms of freedom from valvular reoperations among both treatment groups (log-rank: P = 0.58). Patients with aortic root repair showed higher freedom from recurrent endocarditis compared to patients with aortic root replacement (log-rank: P = 0.022). Patients with aortic root repair exhibited higher event-free survival (defined as a combination end point of freedom from death, valvular reoperation or recurrent endocarditis) compared to patients receiving aortic root replacement (log-rank: P = 0.022). Age increased the risk of mortality with 1.7% per year. Multi-variable adjusted statistical analysis revealed improved long-term event-free survival after aortic root repair (hazards ratio: 0.57, 95% confidence interval: 0.39-0.95; P = 0.031). CONCLUSIONS: Aortic root repair and replacement are feasible options for the surgical treatment of root endocarditis and are complementary methods, depending on the extent of infection. Patients with less advanced infection have a more favourable prognosis. CLINICAL TRIAL REGISTRATION: UN4232 382/3.1 (retrospective study).

BACKGROUND: Primary pericardial mesothelioma (PPM) is a rare form of highly aggressive cancer. Many patients are diagnosed only at an advanced stage. Therefore, the overall survival rate is poor with a median survival of 3 months. In some rare cases, the PPM infiltrates the myocardium causing lethal myocardial dysfunction. CASE SUMMARY: A 66-year-old patient was transferred to our centre with the provisional diagnose of pericarditis of unknown origin. Using extensive cardiac imaging [echocardiography, computed tomography (CT), positron emission tomography-CT, cardiac magnetic resonance imaging, left and right heart catheterization, coronary angiography], PPM was finally diagnosed. After consultation with the oncologists, the heart team decided to resect the tumour first due to impaired haemodynamics and then initiate adjuvant chemotherapy. Intraoperatively, myocardial infiltration of the tumour became apparent, which was not detected preoperatively despite intensive imaging. Complete resection of the PPM was not possible and effective decompression of the ventricle could not be achieved. The patient died on the first postoperative day. DISCUSSION: Surgical therapy is indicated in many forms of cardiac tumours. However, when a tumour invades the myocardium, surgery often comes to its limits. In this case, myocardial invasion of PPM could not be detected despite extensive imaging. We therefore suggest that possible myocardial infiltration by PPM, and thus potential limitations of cardiac surgery, should be considered independently of imaging results when therapeutic options are discussed.
RESUMEN
OBJECTIVES: A treatment dilemma arises when surgery is indicated in patients with infective endocarditis (IE) complicated by stroke. Neurologists recommend surgery to be postponed for at least 1 month. This study aims to investigate the neurological complication rate and neurological recovery potential in patients with IE-related stroke. METHODS: A total of 440 consecutive patients with left-sided IE undergoing surgery were investigated. During follow-up, neurological recovery was assessed using the modified Rankin scale and the Barthel index. Mortality was assessed with regression models adjusting for age. RESULTS: The median follow-up time was 9.0 years. Patients with previous strokes were more likely to suffer from mitral valve endocarditis (29.5% vs 47.4%, P < 0.001). Symptomatic stroke was found in 135 (30.7%) patients; of them, 42 patients presented with complicated stroke (additional meningitis, haemorrhagic stroke or intracranial abscess). Driven by symptomatic stroke, the age-adjusted hospital mortality risk was 1.4-fold [95% confidence interval (CI) 0.74-2.57; P = 0.31] higher and the long-term mortality risk was 1.4-fold higher (95% CI 1.003-2.001; P = 0.048). Hospital mortality was higher in patients with complicated stroke (21.4% vs 9.7%; P = 0.06) only; however, mortality rates were similar comparing uncomplicated stroke versus no stroke. Among patients with complicated ischaemic strokes, the observed risk for intraoperative cerebral haemorrhage was 2.3% only and the increased hospital mortality was not driven by cerebral complications. In the long-term follow-up, full neurological recovery was observed in 84 out of 118 survivors (71.2%), and partial recovery was observed in 32 (27.1%) patients. Neurological recovery was lower in patients with complete middle cerebral artery stroke compared to other localization (52.9% vs 77.6%; P = 0.003). CONCLUSIONS: Contrary to current clinical practice and neurological recommendations, early surgery in IE is safe and neurological recovery is excellent among patients with IE-related stroke.

Remote access perfusion for minimally invasive mitral surgery is commonly achieved by femorofemoral bypass. We describe the use of the carotid artery as an inflow in 2 patients with severe calcifications of the abdominal aorta and the iliac arteries who underwent minimally invasive mitral and tricuspid valve repair. The easy and fast access to the vessel and the lack of interference with the transthoracic clamp and scope are the major advantages of carotid artery compared with other alternatives such as the axillary artery. We propose this technique in candidates for minimally invasive valve procedures with contraindications to femoral perfusion.

A therapeutic dilemma arises when infective endocarditis (IE) is complicated by a neurologic event. Postponement of surgery up to 4 weeks is recommended by the guidelines, however, this negatively impacts outcomes in many patients with an urgent indication for surgery due to uncontrolled infection, disease progression, or haemodynamic deterioration. The current literature is ambiguous regarding the safety of cardiopulmonary bypass in patients with recent neurologic injury. Nevertheless, most publications demonstrate a lower risk for secondary haemorrhagic conversion of uncomplicated ischaemic lesions than the risk for recurrent embolism under antibiotic treatment. Here, we discuss the current literature regarding neurologic stroke complicating IE with an indication for surgery.
RESUMEN
BACKGROUND: Endomyocardial fibrosis (EMF) represents the most common cause of restrictive cardiomyopathy worldwide. Despite a high prevalence in tropical regions, it occasionally occurs in patients who have never visited these areas. While researches have proposed various possible triggers for EMF, etiology and pathogenesis remain largely unknown. Diagnosis is based on patient history, heart failure symptoms, and echocardiographic signs of restrictive ventricular filling, atrioventricular valve regurgitation and frequently apical thrombus. Following is a case report of an Austrian patient with EMF who eventually had to undergo a heart transplant. This case report strives to promote awareness for this in non-tropical areas uncommon but nevertheless detrimental disease. CASE PRESENTATION: A 40-year-old woman was presented at our emergency department with chest pain and fever up to 38.1° Celsius. Plasma troponin-T levels and inflammatory markers were slightly elevated, but the echocardiogram was without pathological findings. The patient was hospitalized on the suspicion of acute myocarditis and discharged soon after improvement. Eight months later, she was presented again with chest pain and symptoms of heart failure. The echocardiogram showed normal systolic left ventricular (LV) function with LV wall thickening and severe restrictive mitral regurgitation as well as aortic and tricuspid regurgitation. Coronary angiogram was normal but right heart catheterization showed pulmonary hypertension due to left heart disease. Further diagnostic workup with cardiac magnetic resonance imaging revealed subendocardial late enhancement and apical thrombus formation in the left ventricle compatible with the diagnosis of EMF. A comprehensive diagnostic workup showed no evidence of infection, systemic immunologic or hematological disease, in particular hypereosinophilic syndrome. After a multidisciplinary consideration of several therapeutic options, the patient was listed for heart transplantation. On the waiting list, she deteriorated rapidly due to progressive heart failure and finally underwent a heart transplantation. Histological examination confirmed the diagnosis of EMF. Six years after her heart transplantation, the patient was presented in an excellent clinical condition. CONCLUSIONS: Even in non-tropical regions, the diagnosis of EMF should always be considered in restrictive cardiomyopathy. Knowledge of the distinct phenotype of EMF facilitates diagnosis, but comprehensive workup and therapeutic management remain challenging and require a multidisciplinary approach.

Transcatheter treatment of structural heart disease is becoming an everyday reality for an increasing number of surgeons, and effective training modalities for basic guide-wire skills, catheter handling, and periprocedural imaging are of growing relevance. In this video tutorial we present a beating-heart porcine model used as a high-fidelity training simulator for transcatheter cardiac valve procedures. We demonstrate a complete transcatheter edge-to-edge mitral valve repair procedure, including periprocedural imaging, clip deployment, and quality control. Various mitral valve pathologies can be simulated, including the demonstrated leaflet prolapse. Trainees practice clip navigation within the left atrium, transmitral passage, and clip orientation as well as grasping mitral valve leaflets to treat mitral regurgitation. Periprocedural imaging is achieved via epicardial echocardiography and left ventricular cardioscopy, and these imaging modalities are also relied on to guide surgeons during the simulations, as required. The beating heart model enables realistic demonstration of the hemodynamic consequences of valve repair, and we believe that this simulator represents a valuable adjunct to surgical training.

OBJECTIVE: Inadequate peripheral venous drainage during minimally invasive cardiac surgery (MICS) is a challenge and cannot always be solved with increased vacuum or increased centrifugal pump speed. The present study was designed to assess the benefit of virtually wall-less transfemoral venous cannulas during MICS. METHODS: Transfemoral venous cannulation with virtually wall-less cannulas (3/8â³ 24F 530-630-mm ST) was performed in 10 consecutive patients (59 ± 10 years, 8 males, 2 females) undergoing MICS for mitral (6), aortic (3), and other (4) procedures (combinations possible). Before transfemoral insertion of wall-less cannulas, a guidewire was positioned in the superior vena cava under echocardiographic control. The wall-less cannula was then fed over the wire and connected to a minimal extracorporeal system. Vacuum assist was used to reach a target flow of 2.4 l/min per m with augmented venous drainage at less than -80 mm Hg. RESULTS: Wall-less venous cannulas measuring either 630 mm (n = 8) in length or 530 mm (n = 2) were successfully implanted in all patients. For a body size of 173 ± 11 cm and a body weight of 78 ± 26 kg, the calculated body surface area was 1.94 ± 0.32 m. As a result, the estimated target flow was 4.66 ± 0.78 l/min, whereas the achieved flow accounted for 4.98 ± 0.69 l/min (107% of target) at a vacuum level of 21.3 ± 16.4 mm Hg. Excellent exposure and "dry" intracardiac surgical field resulted. CONCLUSIONS: The performance of virtually wall-less venous cannulas designed for augmented peripheral venous drainage was tested in MICS and provided excellent flows at minimal vacuum levels, confirming an increased performance over traditional thin wall cannulas. Superior results can be expected for routine use.

Bioprosthetic aortic valves have been used with increasing frequency over the past two decades, often in relatively young patients who may eventually require aortic valve re-operations due to degeneration of the bioprosthesis. Growing experience with minimally invasive aortic valve replacement has prompted surgeons to use minimally invasive approaches also with redo operations for replacement of the aortic valve. This tutorial describes the operative steps for a minimally invasive redo replacement of the aortic valve through an upper ministernotomy. We demonstrate the surgical access, initiation of cardiopulmonary bypass, venting, and cardioplegia strategies. Special situations, such as how to approach patent coronary grafts, the small aortic annulus, and the use of sutureless or rapid deployment valves are demonstrated and discussed. The tutorial shows that minimally invasive redo aortic valve replacement is a safe, effective, and reproducible procedure.

BACKGROUND: Propensity score-matched analysis of the anterolateral minithoracotomy and the partial upper hemisternotomy vs the median sternotomy approach has not been reported to date for isolated aortic valve replacement. METHODS: From 2005 to 2013, isolated aortic valve replacement was performed through a partial upper hemisternotomy in 315 patients (38.9%), through a median sternotomy in 328 patients (40.5%), and through an anterolateral minithoracotomy in 167 patients (20.6%). After propensity score-matched analysis, both minimally invasive techniques were independently compared with median sternotomy in 118 matched pairs. RESULTS: In the anterolateral group, conversion to median sternotomy was significantly higher (17 [14.4%]), a second pump run (6 [5.1%]) and second cross clamp (12 [10.2%]) were significantly more often necessary, the median cross-clamp time (94 minutes; range, 43 to 231 minutes) and median perfusion time (141 minutes; range, 77 to 456 minutes) were significantly longer, and more groin complications occurred (17 [14.4%]), all compared with the median sternotomy group. No difference in perioperative results was identified between the partial upper hemisternotomy and the median sternotomy group. There was no significant difference in 1-year survival among the three groups, although a trend of better survival was observed in the partial upper hemisternotomy group. CONCLUSIONS: In minimally invasive isolated aortic valve replacement, the partial upper hemisternotomy shows similar perioperative outcome as the median sternotomy, whereas, the anterolateral minithoracotomy is associated with more perioperative complications. Therefore, only the partial upper hemisternotomy should be the preferred surgical technique for minimally invasive aortic valve replacement in the daily routine for a broad spectrum of surgeons.

Intrapericardial left-sided ectopic thyroid tissue is a rare entity. We report a 47-year old female patient with an intrapericardial mass mounting the left atrial wall. Two prominent vessels, both originating from the left circumflex artery (LCX), supplied the tumour. Owing to the compression of the left atrium and the left upper pulmonary vein, the patient was highly symptomatic with exertional dyspnoea and ventricular extrasystoles. Histopathological examination showed regressive thyroid adenoma with no signs of malignancy. Complete resection was feasible. The evaluation of thyroid hormone levels was not indicative for diagnosis. Postoperative hormone substitution appeared to be unnecessary.

BACKGROUND: Due to the complex therapy and the required high level of immunosuppression, lung recipients are at high risk to develop many different long term complications. METHODS: From 1993-2000, a total of 54 lung transplantation (LuTx) were performed at our center. Complications, graft and patient survival of this cohort was retrospectively analyzed. RESULTS: One/five and ten-year patient survival was 71.4%, 41.2% and 25.4%; at last follow up (4/2010), twelve patients were alive. Of the 39 deceased patients, 26 died from infectious complications. Other causes of death were myocardial infarction (n=1), progressive graft failure (n=1), intracerebral bleeding (n=2), basilary vein thrombosis (n=1), pulmonary emboli (n=1), others (n=7). Surgical complication rate was 27.7% during the first year and 25% for the 12 long term survivors. Perioperative rejection rate was 35%, and 91.6% for the 12 patients currently alive. Infection incidence during first hospitalization was 79.6% (1.3 episodes per transplant) and 100% for long term survivors. Commonly isolated pathogens were cytomegalovirus (56.8%), Aspergillus (29.4%), RSV (13.7%). Other common complications were renal failure (56.8%), osteoporosis (54.9%), hypertension (45%), diabetes mellitus (19.6%). CONCLUSIONS: Infection and rejection remain the most common complications following LuTx with many other events to be considered.
RESUMEN
BACKGROUND: In aortic valve replacement, a comparison between the anterolateral minithoracotomy and the partial upper hemisternotomy approach has not been reported to date. METHODS: From 2006 to 2012, isolated aortic valve replacement was performed in 1,118 consecutive patients. Aortic valve replacement was performed through a anterolateral minithoracotomy in 166 patients (14.9%) and through a partial upper hemisternotomy in 245 patients (21.9%). A propensity score-matched analysis was performed in 160 matched pairs. RESULTS: Conversion to median sternotomy was significantly higher in the anterolateral group (n = 22, 13.1%) than in the hemisternotomy group (n = 7, 4.4%) (p = 0.004). A second cross-clamp was significantly more often necessary in the anterolateral group (n = 14, 8.8%) than in the hemisternotomy group (n =2, 1.3%) (p = 0.003). The median cross-clamp time was significantly longer in the anterolateral group, 93 minutes (range, 43 to 231 minutes) than in the hemisternotomy group, 75 minutes (range, 46 to 137 minutes) (p < 0.0001). The median perfusion time was significantly longer in the anterolateral group, 137 minutes (range, 81 to 456 minutes) than in the hemisternotomy group, 113 minutes (range, 66 to 257 minutes) (p < 0.0001). Significantly more groin adverse events occurred in the anterolateral group (n = 17, 10.8%) than in the hemisternotomy group (n = 0, 0%) (p < 0.0001). No significant difference in 90-day mortality was seen in the anterolateral group (n = 6, 3.8%) than in the hemisternotomy group (n = 2, 1.3%) (p = 0.16). CONCLUSIONS: The anterolateral minithoracotomy is associated with more perioperative adverse events. The partial upper hemisternotomy is an excellent surgical technique for minimally invasive aortic valve replacement in the daily routine for every staff surgeon.
