Abstract Background Intracardiac blood cysts are very rare primary cardiac tumors. Blood cysts originated from the mitral valve represent a minority of cases, and previous cases have been mainly treated with conventional surgery through median sternotomy. When the tumor involves heart valves and histopathological diagnosis remains unknown preoperatively, minimally invasive surgical resection of an intracardiac tumor can be challenging, especially through an endoscopic approach. We herein present the first case of successful surgical resection for a rare mitral valve originated blood cyst in a minimally invasive, totally thoracoscopic approach. Case presentation An apparently healthy 38-year-old male presented to his local hospital with six months history of palpitation and exertional dyspnea. Transthoracic echocardiography showed a mobile round cystic mass inside the left ventricle, attached to the anterolateral papillary muscle and chordae tendineae of the mitral valve. The local doctor diagnosed an intracardiac tumor and suggested a surgical resection through median sternotomy. However, the patient refused to have a sternotomy. He was then referred to us seeking minimally invasive surgery. We assessed the location, appearance and relationship to nearby structures of the tumor with echocardiography, and made a diagnosis of a suspected primary cystic intracardiac tumor. Since we had enough experience of totally endoscopic mitral surgery, our surgical plan was to resect the tumor in the aid of thoracoscopy, and manage the possible deformation and dysfunction of the cardiac structure if necessary. Using femoro-femoral cannulation and cardiopulmonary bypass, we successfully resected the tumor through a thoracoscopic approach in a closed chest, and well preserved the subvalvular structure and valvular function. Postoperative recovery was quick and uneventful. Pathologic diagnosis confirmed a simple blood cyst. Conclusions Surgical resection is warranted for symptomatic cases of intracardiac blood cysts. With prudent preoperative diagnosis and comprehensive surgical plan, we believe the thoracoscopic approach is a safe, curative and viable alternative for complete resection of cardiac valvular tumors.

Abstract Introduction Totally endoscopic technique has been widely used in cardiac surgery, and minimally invasive totally endoscopic mitral valve surgery has been developed as an alternative to median sternotomy for many patients with mitral valve disease. In this study, we describe our experience about a modified minimally invasive totally endoscopic mitral valve surgery and reported the preliminary results of totally endoscopic mitral valve surgery. The aim of this retrospective study is to evaluate the results of totally endoscopic technique in mitral valve surgery. Material and methods We retrospectively reviewed the profiles of 188 patients who were treated for mitral valve disease by modified totally endoscopic mitral valve surgery at our institution between January 2019 and December 2020. The procedure was performed under endoscopic right minithoracotomy and with femoro-femoral cannulation using the single two-stage venous cannula. Results A total of 188 patients underwent total endoscopic mitral valve surgery. Fifty-six patients had concomitant tricuspid valvuloplasty, 11 patients underwent concomitant ablation of atrial fibrillation and atrial septal defect repair was performed in three patients. Only one patient postoperatively died of multi-organ failure. Two patients were converted to median sternotomy. Except for one patient underwent operation to stop the bleeding from the incision site, no other serious complications nor reintervention occurred during the follow-up period. Conclusions The modified totally endoscopic mitral valve surgery performed at our institution is technically feasible and safe with the same efficacy as reported studies.

We conducted a retrospective comparative analysis of 75 patients undergoing video-assisted mitral valve repair with right minithoracotomy over a period from November 2011 to August 2013. The control group comprised 71 patients operated on mitral valve by using median sternotomy during the same period. Median (25th; 75th) times of cardiopulmonary bypass and aortic cross-clamping were significantly longer in the minimally invasive group (180 [139; 224] and 111 [87; 145] min, respectively) as compared to the controls (84 [69; 117] and 62 [49; 81 ] min, respectively), p<0.01. Fatal outcome occurred in 2 (2.7%) cases in the minimally invasive group versus none in the controls. In both cases death resulted from intraoperative aortic dissection. While ventilation time and intensive care unit stay were comparable across the groups, postoperative respiratory failure occurred in 6 (8%) cases in the minimally invasive group versus none in the controls (p<0.05). No other significant differences in the postoperative course were observed between the groups. The results of the present study are generally consistent with the world's tendencies. On the other hand, complication rates observed in the minimally invasive group present a considerable economic burden and require substantial human resources in the postoperative period.

First Case

Primary tumors of the cardiac valves are rare. One of the most common reasons that left-sided cardiac tumors come to clinical attention is embolization to the systemic circulation. We present two children who suffered left coronary arterial occlusion due to embolization of a sarcoma of the mitral valve. A 6-year-old female who had been admitted to the hospital after cerebrovascular embolization of a fragment of sarcoma of the mitral valve experienced sudden cardiovascular collapse due to occlusion of the left coronary artery. She was placed on extracorporeal membrane oxygenation, and underwent coronary embolectomy and resection of the tumor from the mitral valve and its tendinous cords. Left ventricular function did not improve, and she underwent orthotopic heart transplantation. On follow-up 32 months after transplant, the patient is well, with no evidence of recurrence of or metastasis from the tumor. The tumor arose from the leaflets and tendinous cords of the mitral valve, and was composed grossly of multiple white nodules. Histopathologic evaluation disclosed fragments composed predominantly of peripheral spindle cells in an extensive fibromyxoid stroma. The mildly pleomorphic cells of the tumor gradually blended with adjacent pieces of the mitral valvar leaflet and tendinous cords. Immunohistochemical studies revealed strong staining for vimentin, smooth muscle actin, muscle specific actin, and myoglobin, suggesting myogenic differentiation. The other patient was a 2½-year-old female who died suddenly at home. Grossly and histologically, the tumor was essentially identical to the first case, and there was a 3 cm string-like extension passing into the orifice of the left coronary artery. To put the cases in context, we compare them with other descriptions of this rare type of tumor.

Background: Minimally invasive mitral valve replacement surgery (MIMVR) is gaining popularity for its multifold advantages. Here we report our single-institution experience with MIMVR through the right minithoracotomy over two years. Materials and Methods: This study was a retrospective analytical study. Forty-two patients undergoing MIMVR between August 2019 and July 2021 were included. Recorded perioperative data were collected and evaluated retrospectively. Results: A total of 42 patients were included in the study, of which 29 were females (69%). The mean age was 43.2+/- 8.2 years. Overall 30-day mortality was 2.38% (n = 1). Mean operating time, cardiopulmonary bypass, and aortic cross-clamp times were 264.9 ± 48.7, 151.5 ± 39.8, and 89.8 ± 25.6 minutes, respectively. Tricuspid valve annuloplasty was performed in 8 patients (19%). One patient (2.38%) required conversion to median sternotomy, and three patients (7.1%) underwent re-explorations due to bleeding. The median postoperative hospital stay was 5 days. Conclusions: MIMVR through right minithoracotomy is feasible, safe, and reproducible with low mortality and morbidity. Mitral valve surgery through a small anterior thoracotomy is a good alternative to conventional thoracotomy. Keywords: minimally invasive, minithoracotomy, mitral valve replacement

Background/Aim. The last decade of the 20th century brought up a significant development in the field of minimally invasive approaches to the valvular heart surgery. Potential benefits of this method are: good esthetic appearance, reduced pain, reduction of postoperative hemorrhage and incidence of surgical site infection, shorter postoperative intensive care units (ICU) period and overall in-hospital period. Partial upper median sternotomy currently presents as a state-of-the art method for minimally invasive surgery of cardiac valves. The aim of this study was to report on initial experience in application of this surgical method in the surgery of mitral and aortic valves. Methods. The study was designed and conducted in a prospective manner and included all the patients who underwent minimally invasive cardiac valve surgery through the partial upper median sternotomy during the period November 2008 - August 2009. We analyzed the data on mean age of patients, mean extubation time, mean postoperative drainage, mean duration of hospital stay, as well as on occurance of postoperative complications (postoperative bleeding, surgical site infection and cerebrovascular insult). Results. During the observed period, in the Institute for Cardiovascular Diseases of Vojvodina, Clinic for Cardiovascular Surgery, 17 ministernotomies were performed, with 14 aortic valve replacements (82.35%) and 3 mitral valve replacements (17.65%). Mean age of the patients was 60.78 ? 12.99 years (64.71% males, 35.29% females). Mean extubation time was 12.53 ? 8.87 hours with 23.5% of the patients extubated in less than 8 hours. Mean duration of hospital stay was 12.35 ? 10.17 days (in 29.4% of the patients less than 8 days). Mean postoperative drainage was 547.06 ? 335.2 mL. Postoperative complications included: bleeding (5.88%) and cerebrovascular insult (5.88%). One patient (5.88%) required conversion to full sternotomy. Conclusion. Partial upper median sternotomy represents the optimal surgical method for the interventions on the whole ascendant aorta (including aortic valve) and mitral valve through the roof of the left atrium, with a few significant advantages compared to the full sternotomy surgical approach.

Objective Despite advances in design, modern ventricular assist device placement involves median sternotomy and cardiopulmonary bypass and is associated with infectious/embolic complications. In this study, we examine the feasibility and function of a novel minimally invasive, non–blood-contacting epicardial assist device in a porcine ischemic cardiomyopathy model. Methods Feasibility was first tested in an ex vivo thoracoscopic trainer box with slaughterhouse hearts. Five male Yorkshire swine underwent selective ligation of the circumflex artery to create a posterolateral infarct Twelve weeks after infarct, all animals underwent left minithoracotomy. A custom inflatable bladder was positioned over the epicardial surface of the infarct and firmly secured to the surrounding border zone myocardium with polypropylene mesh and minimally invasive mesh tacks. An external gas pulsation system actively inflated and deflated the bladder in synchrony with the cardiac cycle. All animals then underwent cardiac magnetic resonance imaging to assess ventricular function. Results All subjects successfully underwent off-pump placement of the epicardial assist device via minithoracotomy. Ejection fraction significantly improved from 29.1% ± 4.8% to 39.6% ± 4.23% ( P < 0.001) when compared with pretreatment. End-systolic volume decreased (76.6 ± 13.3 mL vs 62.4 ± 12.0 mL, P < 0.001) and stroke volume increased (28.6 ± 3.4 mL vs 37.9 ± 3.1 mL, P < 0.05) when assisted. No change was noted in end-diastolic volume (105.1 ± 11.4 vs 100.3 ± 12.7). On postmortem examination, mesh fixation and device position were excellent in all cases. No adverse events were encountered. Conclusions Directed epicardial assistance improves ventricular function in a porcine ischemic cardiomyopathy model and may provide a safe alternative to currently available ventricular assist device therapies. Further, the technique used for device positioning and fixation suggests that an entirely thoracoscopic approach is possible.
