Project description:ObjectivesTo investigate how virtual reality (VR) imaging impacts decision-making in atrioventricular valve surgery.MethodsThis was a single-center retrospective study involving 15 children and adolescents, median age 6 years (range, 0.33-16) requiring surgical repair of the atrioventricular valves between the years 2016 and 2019. The patients' preoperative 3-dimesnional (3D) echocardiographic data were used to create 3D visualization in a VR application. Five pediatric cardiothoracic surgeons completed a questionnaire formulated to compare their surgical decisions regarding the cases after reviewing conventionally presented 2-dimesnional and 3D echocardiographic images and again after visualization of 3D echocardiograms using the VR platform. Finally, intraoperative findings were shared with surgeons to confirm assessment of the pathology.ResultsIn 67% of cases presented with VR, surgeons reported having "more" or "much more" confidence in their understanding of each patient's pathology and their surgical approach. In all but one case, surgeons were at least as confident after reviewing the VR compared with standard imaging. The case where surgeons reported to be least confident on VR had the worst technical quality of data used. After viewing patient cases on VR, surgeons reported that they would have made minor modifications to surgical approach in 53% and major modifications in 7% of cases.ConclusionsThe main impact of viewing imaging on VR is the improved clarity of the anatomical structures. Surgeons reported that this would have impacted the surgical approach in the majority of cases. Poor-quality 3D echocardiographic data were associated with a negative impact of VR visualization; thus. quality assessment of imaging is necessary before projecting in a VR format.

Project description:BackgroundGerbode defect is a congenital or acquired communication between the left ventricle and right atrium. While the defect is becoming a more well-recognized complication of cardiac surgery, it presents a diagnostic and therapeutic challenge for providers. This case highlights the predisposing factors and imaging features that may assist in the diagnosis of Gerbode defect, as well as potential approaches to treatment.Case summaryWe report a patient with severe mitral stenosis as a result of remote mediastinal radiation who underwent extensive decalcification during surgical mitral valve replacement and tricuspid valve repair. Following the procedure, he developed progressive heart failure refractory to medical management. Extensive workup ultimately led to the diagnosis of iatrogenic acquired Gerbode defect. Close collaboration between adult cardiology, cardiothoracic surgery, and the congenital cardiology services led to an optimal treatment plan involving percutaneous closure of the defect.DiscussionGerbode defect is a rare complication of invasive procedures involving the interventricular septum or its nearby structures. An understanding of the key echocardiographic features will aid providers in timely diagnosis. Percutaneous repair should be strongly considered for patients who may be poor surgical candidates.

Project description:Recurrent tricuspid regurgitation after failed ring annuloplasty is associated with high mortality rates and unfavourable clinical outcomes. Transcatheter tricuspid valve-in-ring (TVIR) replacement offers an alternative to high-risk surgical reoperation, but challenges remain. We present a case of a 67-year-old male who underwent tricuspid annuloplasty 3 years ago and developed severe recurrent tricuspid regurgitation (regurgitation volume = 36 mL) 6 months ago. To avoid a high-risk thoracotomy, we finally performed TVIR replacement using the novel device, LuX-Valve Plus system, via the transjugular approach. Cardiovascular three-dimensional printing technology was utilized to investigate the distinct advantages offered by the new device in this specific intervention, as well as to simulate the procedure. Successful TVIR replacement resulted in significant symptomatic improvement. TVIR replacement with the LuX-Valve Plus system is feasible for failed annuloplasty ring cases. Patient-specific three-dimensional printed models enable personalized procedural planning, enhancing safety and precision.

Project description:Tricuspid valve (TV) repair techniques other than annuloplasty remain challenging and frequently end in tricuspid valve replacement (TVR) in complicated cases. However, the results of TVR are suboptimal compared with TV repair. This study aimed to evaluate the clinical effectiveness of TV edge-to-edge repair (E2E) compared to TVR for severe tricuspid regurgitation (TR). We retrospectively reviewed 230 patients with severe TR who underwent E2E (n=139) or TVR (n=91) from 2001 to 2020. Clinical and echocardiographic results were analyzed using inverse probability of treatment weighting analysis and propensity score matching. The two groups showed no significant differences in early mortality and morbidities. During the mean follow-up of 106.2±68.8 months, late severe TR and TV reoperation rates were not significantly different between groups. E2E group, however, showed better outcomes in overall survival (p=0.023), freedom from significant tricuspid stenosis (TS) (trans-tricuspid pressure gradient ≥5 mmHg, p=0.021), and freedom from TV-related events (p<0.001). Matched analysis showed consistent results. E2E for severe TR presented more favorable clinical outcomes than TVR. Our study supports that E2E might be a valuable option in severe TR surgery, avoiding TVR.

Project description:Acute afterload mismatch and left ventricular dysfunction after mitral valve repair are well established. The impact of transcatheter tricuspid valve repair (TTVr) on right ventricular (RV) function is less clearly defined. To our knowledge, there are no reports of acute RV dysfunction after TTVr. Here we report a case of acute afterload mismatch after successful TTVr. (Level of Difficulty: Advanced.).

Project description:Intravenous drug use has increased substantially over the past decade, with heroin abuse more than doubling. Injection drug use-related infective endocarditis hospitalizations have similarly increased over the same period. Right-sided infective endocarditis is strongly associated with intravenous drug use, and 90% of right-sided endocarditis involves the tricuspid valve. During the period of the opioid epidemic, tricuspid-related endocarditis rates have increased, while the incidence of surgery for tricuspid endocarditis has increased as much as five-fold. Within this context, optimizing surgical technique for valve repair is increasingly important. In this report, we examine the indications for tricuspid valve surgery for endocarditis, describe specific techniques for tricuspid valve leaflet repair and augmentation, and assess postoperative care and surgical outcomes after both tricuspid valve repair and replacement for infective endocarditis.

Project description:BackgroundSymptomatic tricuspid regurgitation (TR) is increasingly prevalent and impairs quality of life and survival, despite medical treatment. Transcatheter tricuspid valve repair (TTVR) has recently become available as a treatment option for patients not eligible for tricuspid valve surgery. In this study we describe the early experience with TTVR in the Netherlands.MethodsAll consecutive patients scheduled for TTVR in two tertiary hospitals were included in the current study. Patients were symptomatic and had severe functional TR. TTVR was performed either with the MitraClip (off-label use) or dedicated TriClip delivery system and device. Procedural success was defined as achievement of clip implantation, TR reduction ≥ 1 grade and no need for re-do surgical or transcatheter intervention. Clinical improvement was evaluated after 4 weeks.ResultsTwenty-one patients (median age 78 years, 33% male, 95% New York Heart Association class ≥ 3, 100% history of atrial fibrillation) underwent TTVR. Procedural success was achieved in 16 patients, of whom 15 reported symptomatic improvement (New York Heart Association class 1 or 2). There was no in-hospital mortality and no major complications occurred. Baseline glomerular filtration rate and TR coaptation gap size were associated with procedural success.ConclusionThe current study showed that TTVR seems a promising treatment option for patients with severe functional TR deemed high risk for surgery. Successful TR reduction is most likely in patients with limited coaptation gap size and strongly determines clinical benefit. Adequate patient selection and timing of treatment seem essential for an optimal patient outcome.

Project description:Transcatheter tricuspid intervention is a rapidly evolving field with multiple classes of therapeutic devices currently in development. Procedural success in tricuspid intervention is predicated on appropriate device selection for patient specific anatomy and satisfactory imaging for intra-procedural guidance. This review will outline protocols and methodology for multi-modality imaging assessment of the tricuspid valve and associated structures, with emphasis on anatomic and functional characteristics that determine suitability for each class of tricuspid intervention. Intra-procedural imaging requirements for each class of device, with design and procedural imaging guidance of specific devices, will also be addressed.
