Mechanical Circulatory Support Strategies in Takotsubo Syndrome with Cardiogenic Shock: A Systematic Review.

Background: Takotsubo syndrome is, by definition, a reversible form of acute heart failure. If cardiac output is severely reduced, Takotsubo syndrome can cause cardiogenic shock, and mechanical circulatory support can serve as a bridge to recovery. To date, there are no recommendations on when to use mechanical circulatory support and on which device is particularly effective in this context.

Alternative minimally invasive surgical explantation techniques for failed transcatheter mitral valve repair devices.

Objective: The use of transcatheter mitral valve repair (TMVr) devices is increasing in elderly and high-risk patients. However, the increasing number of patients with recurrent mitral regurgitation (MR) has confronted surgeons with the issue of how to explant the devices and whether the mitral valve should be repaired or replaced. The aim of the study is to summarize our clinical experience with the explantation of different TMVr devices and to provide alternative surgical techniques that can be performed in different clinical scenarios.

Image-based ring size prediction for mitral valve repair.

Objectives: Annuloplasty rings are routinely used in mitral valve repair (MVr). However, accurate annuloplasty ring size selection is essential to obtain a favourable outcome. Moreover, ring sizing can be challenging in some patients and is highly influenced by surgeons' experience.

"UFO procedure" for massive aortic and mitral annular calcification involving left atrial and ventricular myocardium: a potential radical solution.

Background: The "UFO procedure" was initially developed as a surgical option to enlarge the aortic annulus in patients requiring valve replacement. This technique can be employed to treat extensive endocarditis located in the intervalvular fibrous body (IVFB). One of the indications for a "UFO procedure" is massive aortic and mitral valve calcification.

Minimally Invasive Extirpation of Benign Atrial Cardiac Tumors: Clinical Follow-Up and Survival.

Objective: Evidence determining the optimal treatment for cardiac tumors is rare. We report our midterm clinical outcome and patient characteristics of our series undergoing atrial tumor removal through a right lateral minithoracotomy (RLMT).

Methods: From 2015 to 2021, 51 patients underwent RLMT for atrial tumor extirpation.

HeartWare to HeartMate 3 left ventricular assist device exchange via a left lateral thoracotomy.

A continuous-flow left ventricular assist device implant is a well-established therapy for patients with end-stage heart failure. Currently, the HeartMate 3 device is the only commercially available durable left ventricular assist device. Therefore, patients on HeartWare HVAD support who require a pump exchange must have a HeartMate 3 implanted.

Leaflet-splitting device to prevent coronary artery obstruction in valve-in-valve transcatheter aortic valve implantation.

Coronary artery obstruction is a life-threatening complication of transcatheter aortic valve replacement procedures, and current preventive strategies are suboptimal. The novel ShortCut device splits bioprosthetic valve leaflets that are at risk of causing coronary artery obstruction after transcatheter aortic valve implantation, allowing for normal coronary flow. In this video tutorial, we demonstrate a valve-in-valve transcatheter aortic valve implantation using a dedicated leaflet-splitting device for prevention of coronary artery obstruction in transcatheter aortic valve replacement.

Minimally invasive aortic valve replacement has become a feasible approach to treat various aortic valve pathologies with limited procedural trauma. Several minimally invasive aortic valve replacement approaches with different levels of complexity and technical requirements are currently available.

Single-Center Experience With a Self-Expandable Venous Cannula During Minimally Invasive Cardiac Surgery.

Objective: Venous drainage is often problematic in minimally invasive cardiac surgery (MICS). Here, we describe our experience with a self-expandable stent cannula designed to optimize venous drainage.

Methods: The was used in 58 consecutive patients undergoing MICS for mitral valve disease ( = 40), left atrial myxoma ( = 3), left ventricular outflow tract obstruction ( = 1), and aortic valve replacement via a right anterior minithoracotomy ( = 14) procedures.

Standard Transfemoral Transcatheter Aortic Valve Replacement.

The introduction of the transcatheter aortic valve implantation procedure has revolutionized the standards of care in patients with aortic valve pathologies and has significantly increased the quality of the medical treatment provided. The durability and constant technical improvements in the modern transcatheter aortic valve implantation procedure have broadened the indications towards younger patient groups with low-risk profiles. Therefore, transcatheter aortic valve implantation now represents an effective alternative for surgical aortic valve replacement in a large number of cases.

Factors associated with an unsuccessful fast-track course following minimally invasive surgical mitral valve repair.

Objectives: Analyses of fast-track (FT) processes demonstrated that low-risk cardiac surgical patients require minimal intensive care, with a low incidence of mortality or morbidity. We investigated perioperative factors and their association with fast-track failure (FTF) in a retrospective cohort study of patients undergoing minimally invasive mitral valve surgery.

Methods: Patients undergoing minimally invasive surgical mitral valve repair for Carpentier type I or type II mitral regurgitation between 2014 and 2020 were included in the study.

This paper presents the first transcatheter management of severe aortic regurgitation in a 77-year-old woman with a criss-cross heart-an extremely rare and complex congenital heart disease. The procedure achieved an elimination of aortic regurgitation and resulted in a remarkable improvement of the patient's physical condition. ().

Periareolar endoscopic minimally invasive cardiac surgery: postoperative scar assessment analysis.

Objectives: The standard approach for minimally invasive cardiac surgery (MICS) for repair of the atrioventricular valves is a right lateral minithoracotomy. In this study, we report our experience with a periareolar endoscopic approach, which aims at an optimal cosmetic outcome while preserving optimal clinical outcomes.

Methods: All patients underwent periareolar endoscopic MICS using high-definition three-dimensional endoscopic visualization without additional rib-spreading.

Minimally invasive mitral valve surgery after failed transcatheter mitral valve repair in an intermediate-risk cohort.

Objectives: Although clinical experience with transcatheter mitral valve interventions is rapidly increasing, there is still a lack of evidence regarding surgical treatment options for the management of recurrent mitral regurgitation (MR). This study provides guidance for a minimally invasive surgical approach following failed transcatheter mitral valve repair, which is based on the underlying mitral valve (MV) pathology and the type of intervention.

Methods: A total of 46 patients who underwent minimally invasive MV surgery due to recurrent or residual MR after transcatheter edge-to-edge repair or direct interventional annuloplasty between October 2014 and March 2021 were included.

Right Antero-Lateral Mini-Thoracotomy Surgical Aortic Valve Replacement.

Over the past few decades, the field of minimally invasive cardiac surgery has significantly broadened. Novel surgical and endovascular techniques have been developed for the treatment of aortic valve pathologies. Surgical aortic valve replacement (SAVR) through a right antero-lateral (mini-)thoracotomy (RALT) has gained approval due to its limited postoperative trauma, faster rehabilitation and sufficient pain control.

David Procedure as Valve-Sparing Root Replacement.

Composite replacement of the aortic root and aortic valve is a valid surgical strategy in a case of annuloaortic ectasia. However, valve-sparing root replacement procedures have become the gold standard in cases with a morphologically intact or at least repairable aortic valve, and offer several advantages compared to conventional replacement techniques. Above all, the David procedure has become established as a well-known valve-sparing root replacement strategy with excellent short- and long-term outcomes, and it has been further applied to additional patient populations with characteristics like a bicuspid aortic valve or in the setting of acute type A aortic dissection.

Endoaortic balloon occlusion in minimally invasive mitral valve surgery.

Minimally invasive mitral valve surgery has become a standardized and well-established approach to treat mitral valve disease and is associated with limited procedural trauma. Nevertheless, it remains a technically demanding procedure with a steep learning curve, and new manual skills need to be acquired. Various technical solutions have been adopted and implemented to overcome the challenges associated with this surgical technique.

Percutaneous transseptal transcatheter mitral valve-in-valve implantation under endovascular cerebral protection.

Various interventional and minimally invasive surgical approaches are currently available for the treatment of mitral valve pathologies. However, only a few of these options are applicable in patients with previously operated on mitral valves. In this case report, we provide detailed insight into the step-by-step guidance of a percutaneous transseptal transcatheter mitral valve-in-valve implant under cerebral protection in a patient with a deteriorated surgically implanted mitral bioprosthesis.

Transcatheter aortic valve-in-valve implantation under cerebral protection in a patient with a deteriorated 19-mm rapid-deployment bioprosthetic valve.

The introduction of transcatheter aortic valve implantation (TAVI) has dramatically improved the treatment of valvular pathologies in high-risk patients. Additionally, transcatheter aortic valve implantation can be successfully applied in patients with deteriorated surgical bioprosthetic valves, representing an attractive alternative to a redo operation. Valve-in-valve transcatheter aortic valve implantations can be especially challenging in patients with a small-diameter prosthesis and patient-prosthesis mismatch.

Partial ring annuloplasty in the management of mitral annular calcification.

Mitral annular calcification (MAC) complicates the management of mitral valve (MV) disease, regardless of its etiology. Strategies to address MV surgery in MAC include two main options with their own pros and cons; respect and resect strategy. Here, we present a case of minimally-invasive MV repair with partial annuloplasty in the management of noncircumferential MAC with respect to strategy.

Transcatheter mitral valve implantation in the ongoing structural heart revolution.

Transcatheter mitral valve implantation (TMVI) has emerged as a less invasive approach potentially surmounting some of the current hurdles associated with transcatheter edge-to-edge repair and high-risk mitral valve surgery. In this review, we aimed to outline the main scenarios in the TMVI field, highlight current and upcoming devices, and describe challenges and clinical results. Finally, we briefly discuss the future perspectives for this emerging field and how TMVI might further advance the field of transcatheter treatments of mitral valve disease.

A system for real-time multivariate feature combination of endoscopic mitral valve simulator training data.

Purpose: For an in-depth analysis of the learning benefits that a stereoscopic view presents during endoscopic training, surgeons required a custom surgical evaluation system enabling simulator independent evaluation of endoscopic skills. Automated surgical skill assessment is in dire need since supervised training sessions and video analysis of recorded endoscope data are very time-consuming. This paper presents a first step towards a multimodal training evaluation system, which is not restricted to certain training setups and fixed evaluation metrics.
