BACKGROUND: Complex mitral valve disease can require surgical repair techniques that are challenging in a minimally invasive context and may expose patients to prolonged cardiopulmonary bypass and cross clamp times. Here, we review our simplified stepwise operative approach for the treatment of complex bileaflet mitral disease, on early outcomes and mid-term follow-up. METHODS: One hundred and forty consecutive patients with bileaflet disease underwent video-assisted right minimally invasive mitral valve repair at our surgical center between 2008 and 2016...

Tricuspid regurgitation (TR) presents as either primary valve pathology or secondary to pulmonary or left-sided heart disease. Severe TR portends a worse prognosis independent of age, right ventricular size and function, severe left ventricular dysfunction, and increased pulmonary arterial pressures. Surgical treatment for TR has mostly been limited to patients undergoing mitral valve repair since those at high surgical risk are not candidates for traditional TR surgery. For these patients, minimally invasive techniques could be of great benefit, yet these techniques have been slow to develop because of the various anatomic and physiological aspects of the tricuspid valve apparatus...

OBJECTIVES: Minimally invasive mitral valve surgery (mini-MVR) has numerous associated benefits. However, many studies fail to include greater-risk patients. We hypothesized that a minimally invasive approach in a representative cohort provides excellent outcomes with reduced resource utilization. METHODS: Mitral valve surgical records from 2011 to 2016 were paired with institutional financial records. Patients were stratified by approach and propensity-score matched to balance preoperative difference...

INTRODUCTION: Minimally invasive cardiac surgery (MICS), via minithoracotomy, is thought to be a fast track to extubation and recovery after surgery. Chronic pain, due to intercostal nerve injury, develops in up to 50% of postthoracotomy patients.A number of regional anaesthesia and analgesia techniques may be employed, and the anaesthesiologists play a key role in facilitating optimal outcomes after surgery. METHODS: We report a case of postoperative pain management with a local anesthetic infiltration for MICS...

INTRODUCTION: Aortic valve replacement (AVR) is the gold standard for the treatment of severe or symptomatic aortic valve stenosis. Less invasive procedures have been developed as an alternative to the conventional technique of full sternotomy approach with stented prosthesis. The Perceval® aortic valve (LivaNova, Milan, Italy) is a sutureless bioprosthesis, of which several reports have shown promising results in terms of mortality, morbidity and hemodynamic performance, especially with a less invasive approach...

OBJECTIVE: Leg ischemia is a serious complication of femoral artery cannulation. The primary aim of this study was to assess the safety and efficacy of a novel bidirectional femoral arterial cannula (Sorin Group USA, a wholly owned subsidiary of LivaNova PLC, Arvada, CO USA) that provides both antegrade and retrograde flow, in patients undergoing peripheral cannulation for cardiopulmonary bypass during cardiac surgery. METHODS: Patients undergoing routine cardiac surgery requiring femoral artery cannulation for cardiopulmonary bypass were identified preoperatively...

Reoperative mitral valve surgery (MVS) through a median sternotomy (ST-MVS) can be particularly challenging due to dense adhesions and is known to carry a substantial risk of injuries to vascular structures. These injuries occur in 7-9% of cases and are associated with increased mortality rates. A valid alternative that could avoid the risks associated with redo ST-MVS is the right anterolateral minithoracotomy (MT-MVS) approach. The aim of this study was to quantify the effects of MT-MVS compared with those of ST-MVS on morbidity and mortality among patients who underwent prior cardiac surgery through a sternotomy...

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 (3/8″ 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)...

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is a minimally invasive approach to aortic valve replacement. However, critical cardiovascular collapse can occur during the procedure for various reasons. CASE PRESENTATION: A 90-year-old man with severe aortic stenosis and left circumflex artery stenosis developed acute torrential mitral regurgitation (MR) during TAVR. The valve deployment process induced left ventricular dyssynchrony due to left bundle-branch block and myocardial ischemia in the left circumflex artery region with torrential MR...

BACKGROUND: Although minimally invasive mitral valve repair (MIMVR) is increasingly being performed, only a few clinical studies from Japanese institutions have been reported.Methods and Results:From 2006 to 2017, 387 consecutive patients (135 females, mean age 56±13 years) underwent an initial isolated MIMVR through a right minithoracotomy. The mitral etiology was degenerative in 348, functional in 22, and endocarditis in 13 cases. Repair techniques included leaflet resection/plication in 280, chordal reconstruction in 109, and annuloplasty alone in 24 patients, and concomitant procedures included tricuspid valve repair and atrial fibrillation ablation in 70 (18...

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: Robotic mitral valve replacement (MVR) emerged in the late 1990s as an alternative approach to conventional sternotomy. With the increased use of bioprosthetic valves worldwide and strong patient desire for minimally invasive procedures, the safety and feasibility of robotic MVRs with bioprosthetic valves require investigation. METHODS: Between January 2013 and May 2017, 52 consecutive patients underwent robotic MVRs using the da Vinci Si surgical system (Intuitive Surgical Inc...

We describe a hybrid surgical-interventional technique for minimally-invasive implantation of a transcatheter aortic valve in the mitral position. This technique does not require circular mitral annular calcification and minimizes the risk for left ventricular outflow tract obstruction. We believe this technique represents a useful approach for surgeons and interventional cardiologists until specialized transcatheter mitral valve devices become available.

Minimally invasive mitral valve repair procedures including MitraClip® are becoming increasingly common. For cases of complex or diseased anatomy, clinicians may benefit from using a patient-specific cardiac phantom for training, surgical planning, and the validation of devices or techniques. An imaging compatible cardiac phantom was developed to simulate a MitraClip® procedure. The phantom contained a patient-specific cardiac model manufactured using tissue mimicking materials. To evaluate accuracy, the patient-specific model was imaged using computed tomography (CT), segmented, and the resulting point cloud dataset was compared using absolute distance to the original patient data...

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...
