Minimally invasive valve surgery

Joseph Lamelas, Guilherme V Silva, Subhasis Chatterjee
Mitral annular calcification can pose a formidable surgical challenge in the setting of mitral valve replacement for mitral stenosis. Although there are reports of transapical valve-in-valve transcatheter mitral valve replacement in the setting of degenerated bioprosthetic mitral valve replacement, there is less experience with transcatheter mitral valve replacement for mitral annular calcification. This report describes a patient who previously received a transcatheter aortic valve replacement and then subsequently underwent a minimally invasive right thoracotomy for transcatheter mitral valve replacement with a successful result...

BACKGROUND: Trials suggest that bronchoscopic lung volume reduction (BLVR) with endobronchial valve (EBV) implantation may produce similar effects as lung volume reduction surgery, by inducing atelectasis and reducing hyperinflation through a minimally invasive procedure. This study sought to investigate the efficacy and safety of BLVR with EBV for advanced emphysema. METHODS: We searched PubMed, EMBASE, Web of Science, CINAHL,, and Cochrane Library databases for randomized controlled trials comparing EBV implantation versus standard medical treatment or sham bronchoscopy...

Mitral regurgitation is the most common valvular disease and significant (moderate/severe) mitral regurgitation is found in 2.3% of the population older than 65 years. New transcatheter minimally invasive technologies are being developed to address mitral valve disease in patients deemed too high a risk for conventional open-heart surgery. There are several features of the mitral valve (saddle-shaped noncalcified annulus with irregular leaflet geometry) that make a transcatheter approach to repair or replacing the valve more challenging compared with the aortic valve...

INTRODUCTION: Local excision (LE) is used in early rectal cancer and other pathologies for diagnostic purposes and curative treatment, as well as for palliative surgery in patients who are medically unfit for radical resection. Recently, transanal minimally invasive surgery (TAMIS) has been increasingly accepted as a means for performing LE. Here, we present a TAMIS technique for LE to which endoscopic submucosal dissection was applied. MATERIALS AND SURGICAL TECHNIQUE: We used conventional laparoscopic instruments, including a 10-mm 30° camera...

Background: Minimally invasive mitral valve surgery (MVS) via right mini-thoracotomy has recently attracted a lot of attention. Minimally invasive MVS shows postoperative results that are comparable to those of conventional MVS through the median sternotomy as per various earlier studies. Methods: Between 2000 and 2016, a total of 669 isolated mitral valve procedures for isolated mitral valve regurgitation were performed. A propensity score-matched analysis was generated for the elimination of the differences in relevant preoperative risk factors between the cohorts and included 227 patient pairs...

BACKGROUND: The reduction of RV function after cardiac surgery is a well-known phenomenon. It could persist up-to one year after the operation and often leads to an incomplete recovery at follow-up echocardiographic control. The aim of the present study is to analyze the impact of different modalities of pericardial incision (lateral versus anterior) and of myocardial protection protocols (Buckberg versus Custodiol) onto postoperative RV dynamic by relating two- and three-dimensional echocardiographic parameters in patients undergoing mitral valve repair through minimally invasive or traditional surgery approach...

Mitral regurgitation (MR) is the most prevalent valvular heart disease (VHD) and represents an important cause of heart failure. Medical therapy has a limited role in improving symptoms and does not hinder the progression of valvular disease. Surgery is the treatment of choice for severe symptomatic MR; valve repair is currently the preferred surgical approach because it reduces peri-operative mortality and ensures a good medium- to long-term survival outcome. Nevertheless, a non-negligible proportion of patients with indications for surgical correction are considered to be at prohibitive perioperative risk, mainly because of old age and multiple comorbidities...

BACKGROUND: Cardiac surgery for myelodysplastic syndrome (MDS) patients is challenging because anemia and neutropenia develop as a result of the syndrome, leading to infection and bleeding tendency during surgery. We report the case of minimally invasive mitral valve repair via a right mini-thoracotomy and perioperative use of granulocyte colony-stimulating factor (G-CSF) in a patient with MDS. CASE PRESENTATION: A 77-year-old man with myelodysplastic syndrome (MDS) was referred for surgical treatment for mitral valve regurgitation and underwent a minimally invasive mitral valve repair via a right mini-thoracotomy (MICS mitral procedure)...

The anaesthesiological management of patients scheduled for cardiac surgery has been refined distinctively over the last decade due to different reasons. The continuing growth of the elderly patient population and the increasing number of combined cardiac surgery procedures in octogenarians on the one hand are one aspect. The rapid development of minimally invasive cardiac surgery and the enhancements in mechanical, artificial heart assist devices on the other hand can be seen as additional decisive factors...

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...

An 88-year-old woman was diagnosed with aortic stenosis and an aortic annulus that was too narrow to perform transcatheter aortic valve implantation. Surgery was performed through a 7-cm right mini-thoracotomy at the fourth intercostal space. A 19-mm aortic valve bioprosthesis was implanted after root enlargement. The fourth intercostal space was a suitable site for aortic root enlargement because of the shorter skin-to-root distance and the detailed exposure of the aortic valve after cutting the aortic wall...

BACKGROUND: A sternal-sparing approach to surgery of the proximal aorta could decrease postoperative morbidity. METHODS: To determine the potential benefits of using a minimally invasive right thoracotomy approach for the treatment of ascending aortic pathology, we retrospectively reviewed our experience in patients who required circulatory arrest for the treatment of ascending aortic pathology (with or without aortic valve involvement) between January 2009 and November 2014 (N=177)...

Minimally invasive aortic valve replacement has been used for more than 20 years, but its uptake has been limited. The volumes have increased steadily over the last 10 years, but it is still not regarded as a mainstream procedure. The issue, to some extent, is due to the lack of perceived evidence that minimal access incisions confer any benefit other than cosmetic appearance. In this article, the current literature on minimally invasive aortic valve replacement is reviewed, and it is concluded that benefits are demonstrable, particularly in higher risk, comorbid settings...

Aortic valve replacement via a full sternotomy remains the gold standard for aortic stenosis treatment; however, minimally invasive techniques have grown in popularity and continue to evolve. A recent evolution of minimally invasive aortic valve replacement is endoscopic surgical aortic valve replacement: a miniaturized surgical approach under video guidance. To ensure a safe and reproducible procedure, we have developed 'must dos' and 'preferences' for endoscopic surgical aortic valve replacement. These include specific endoscopic surgical skills to avoid severe adverse events or an emergency conversion to a full sternotomy...

Cardiac surgery has adapted to new demands and the development of new technologies has become a necessity. With this in mind, the interest in minimally invasive aortic valve replacement has grown tremendously. It is evident that the learning curve is an important consideration in the adoption of new technologies and has an impact on outcomes while it is being navigated. In this review, we discuss the process of knowledge transfer and quality control in the setting of minimally invasive aortic valve replacement...

Minimally invasive aortic valve replacement (MIAVR) has proved to be a safe approach for the treatment of aortic valve stenosis and/or insufficiency and is associated with a number of additional benefits for patients. This includes reduced blood loss, reduced transfusion requirements, reduced length of hospital stay and improved aesthetic appearance. As all types of minimally invasive surgery rely on optimizing exposure within a more limited field of view, a thorough preoperative assessment of patients is important to identify and address potential exposure problems...

Importance: Non-vitamin K oral anticoagulants (NOACs) are increasingly prescribed for patients to treat or prevent arterial or venous thromboembolism. The following 4 NOAC agents are approved by the US Food and Drug Administration for clinical use: dabigatran etexilate, apixaban, edoxaban tosylate, and rivaroxaban. A good understanding of these agents' pharmacologic properties is important for surgeons given their marked differences compared with warfarin sodium. This review highlights key practical issues surrounding the use of NOACs in the perioperative setting...

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...
