BACKGROUND:  Isolated tricuspid valve (TV) surgery is considered a high risk-procedure. The optimal surgical approach is controversial. We analyzed our experience with isolated TV redo surgery performed either minimally invasively (redo-MITS) or through sternotomy. METHODS:  We retrospectively analyzed all patients with previous cardiac surgery who underwent redo-MITS ( n  = 26) and compared them to redo-Sternotomy ( n  = 17). A group of primary-MITS ( n  = 61) served as control...

OBJECTIVES: Minimally invasive aortic valve replacement has proven its value over the last decade by its significant advancement and reduction in mortality, morbidity and admission time. However, minimally invasive aortic valve replacement is associated with some on-site difficulties such as limited aortic annulus exposure. Currently, computed tomography scans are used to evaluate the anatomical relationship among the intercostal spaces, ascending aorta and aortic valve prior to surgery...

Kazuto Miyata, Sayaka Shigematsu
Inverted left atrial appendage (LAA) is a rare complication in cardiac surgery. The echocardiographic appearance often leads to misdiagnosis of thrombus or some other cardiac mass. Patients misdiagnosed in this way often undergo unnecessary anticoagulation or surgical treatment. Recently, minimally invasive mitral valve surgery (MIMVS) has become more widespread. However, as the incision for MIMVS through the right thoracotomy is very small, the inverted LAA is not within the surgical field of the cardiac surgeon...

Libman-Sacks endocarditis is a relatively rare sterile verrucous vegetative lesion observed in systemic lupus erythematosus (SLE)/antiphospholipid syndrome (APLS) patients. Most patients with this condition are asymptomatic. Here we report a case of a 46-year-old woman with APLS secondary to SLE complicated with frequent thromboembolic events due to a mitral valve mass. We performed minimally invasive mitral valve replacement with a mechanical prosthetic valve, and she was successfully discharged 14 days after surgery...

Atrial fibrillation is associated with increased morbidity and mortality in patients undergoing mitral valve surgery. There is a growing consensus that patients with preexisting atrial fibrillation should undergo surgical ablation at the time of mitral valve surgery. Novel surgical ablation techniques, including cryoablation, have been developed to facilitate concurrent minimally invasive procedures. This video tutorial describes a combined cryo-maze procedure and mitral valve repair through an upper ministernotomy in a patient with long-standing persistent atrial fibrillation and severe mitral regurgitation...

OBJECTIVES: Excellent outcomes after minimally invasive aortic valve replacement (mini-AVR) have been reported. Therefore, mini-AVR has become a popular treatment option in many cardiac surgery centres. However, whether obese patients particularly benefit from mini-AVR remains unclear. The aim of the present study was to evaluate outcomes of AVR performed through partial upper sternotomy compared to AVR through a full sternotomy (full-AVR) in obese patients. METHODS: We retrospectively reviewed the medical records of all patients who underwent isolated AVR at our institution, and 217 consecutive obese [body mass index (BMI) >30 kg/m2] patients were identified...

Background: This study aimed to investigate the specific causes for switching patients from minimally invasive transthoracic occlusion to surgical repair under cardiopulmonary bypass (CPB). By retrospectively analyzing 340 cases, we sought to provide the clinical reference for improving the success rate of minimally invasive transthoracic device closure of ventricular septal defect (VSD). Methods: Among the 340 patients who underwent transthoracic closure of VSDs in the past 3 years at our hospital, 26 patients needed to be switched to surgical repair under CPB due to failure of transthoracic closure...

Minimally invasive surgical mitral valve repair (MVRepair) has become routine for the treatment of mitral valve regurgitation, and indications have been expanded to include reoperations. Current European Society of Cardiology/European Association for Cardio-Thoracic Surgery guidelines for the management of valvular heart disease recommended standards in terms of mitral valve disease differentiation, timing of intervention and surgical techniques to improve patient care. Numerous minimally invasive techniques to lessen the invasiveness have been described, such as the minimal-access J-sternotomy (ministernotomy), the parasternal incision, the port-access technique and the right minithoracotomy...

OBJECTIVES: Favourable outcomes with mitral annuloplasty have been achieved with transapical cardioscopic (TAC) surgery in a survival animal model. In addition, experimental TAC on a non-survival animal model also showed adequate access to remove the native mitral valve and implant a prosthetic valve, but the surgical procedure took a long time and lacked follow-up data. The goal of this study was to develop a clinically translatable TAC mitral valve replacement (MVR) procedure using technical and instrumental refinements to reduce the surgical time and to evaluate functional recovery and short-term durability using a survival porcine model...

PURPOSE: Minimally invasive aortic valve replacement (MIAVR) procedures remain more complex and technically challenging compared to conventional full sternotomy surgery. This technique involves a restricted surgical field and a limited workspace, which is, at present, strictly reserved for the most experienced surgeons. The MIAVR clinical outcomes are strongly dependent on the appropriate choice of the thoracic incision. This work presents a decision support system to optimize, through an interactive visualization interface, the exposure of the target structure in a limited field of view...

OBJECTIVE: Despite excellent long-term results reported for a trans-aortic septal myectomy for hypertrophic obstructive cardiomyopathy (HOCM), surgery for patients with diffuse hypertrophy is very challenging. In addition, a left ventricular outflow obstruction is often aggravated by an abnormal mitral valve and subvalvular apparatus. METHODS: We performed video-assisted minimally invasive trans-mitral septal myectomy procedures in 3 patients with diffuse-type HOCM, who were highly symptomatic despite maximal medical therapy...

BACKGROUND: Minimally invasive aortic valve replacement (mAVR) is gaining clinical acceptance, however, it is associated with increased operative times due to limited surgical field and access. The Cor-Knot is an automated fastening device designed to facilitate suture fastening, but clinical data in mAVR are lacking. METHODS: From May 2014 to February 2017, 92 patients underwent mAVR at our center with 39 valves secured with manually-tied (MT) sutures and 53 valves entirely secured with the Cor-Knot (CK)...

BACKGROUND:  Minimally invasive mitral valve surgery (MIMVS) is superior to "classical" mitral valve surgery via a sternotomy regarding wound healing and postoperative pain. It is however a more challenging procedure. Patients' preference is leading clearly toward minimally invasive approaches, and surgeons are driven by upcoming new technologies in interventional procedures such as the MitraClip. Especially in re-do cases, the access via right mini-thoracotomy, as previously non-operated situs, is a possible advantage over a re-sternotomy...

OBJECTIVES: Simultaneous surgical off-pump coronary revascularization and transcatheter aortic valve implantation (TAVI) as a hybrid procedure may be a therapeutic option for patients with a TAVI indication who are not suitable for percutaneous coronary intervention and for patients who have an indication for combined surgical aortic valve implantation and coronary artery bypass grafting but present with a porcelain aorta. Early outcomes of these patients are analysed in this study. METHODS: From February 2011 to April 2017, hybrid TAVI/off-pump coronary artery bypass (OPCAB) was performed in 12 (60%) patients, hybrid TAVI/minimally invasive direct coronary artery bypass in 6 (30%) patients and staged TAVI/OPCAB in 2 (10%) patients...
