Transcatheter coil embolization for large pulmonary arteriovenous fistulae through an artificial tricuspid ball valve.

ABSTRACT: Pulmonary arteriovenous fistulae (PAFs) occur congenitally or are acquired. A PAF can cause hypoxemia, sudden death from rupture, abscess formation, and embolism. Treatment for PAF is transcatheter embolization or surgery. Transcatheter embolization is the first choice of treatment; however, this treatment is impossible to perform if a patient has had tricuspid or pulmonary valve replacement. In this paper, we describe a case of PAFs complicated with tricuspid valve replacement with a ball valve (which had been performed 40 years earlier) that was treated with transcatheter embolization. <Learning objective: Although the ball valve was discontinued more than 40 years ago, it is still the only mechanical valve that allows catheter passage. We report a case of successful treatment of pulmonary arteriovenous fistula by passing a catheter through a ball valve.>.

Tricuspid Leaflet Gap-Reduction Maneuvers During Transcatheter Tricuspid Valve Repair.

Project description:Transcatheter tricuspid valve edge-to-edge repair (T-TEER) has emerged as an option for treating patients with tricuspid regurgitation. Few studies have explored intraprocedural maneuvers to optimize leaflet-grasping T-TEER in order to improve technical success. This case series of 3 patients describes maneuvers that facilitated T-TEER in patients with large coaptation gaps or short leaflet lengths. (Level of Difficulty: Advanced.).

Transcatheter Tricuspid Valve Replacement: Principles and Design.

Project description:Tricuspid regurgitation (TR) may affect as much as 65-85% of the population with the prevalence of moderate-to-severe TR in the United States reported at greater than 1.6 million. However, only 8,000 tricuspid valve operations are performed annually in the United States. As severe TR is associated with poor outcomes, there is an unmet clinical need for surgical or percutaneous transcatheter based treatment of TR. Over the last two decades there have been significant developments in percutaneous transcatheter based therapies for valvular disease. However, this progress has not been mirrored for the tricuspid valve until recently; we are now at a cross-roads of new transcatheter devices becoming available for treatment of TR. In this review, we discuss the principles of performing transcatheter tricuspid valve replacement, analyze the devices that can be utilized and outline the challenges related to this procedure.

Current Status of Transcatheter Tricuspid Valve Therapies.

Project description:Tricuspid regurgitation is a complex disease that carries a poor prognosis, and surgical repair is associated with high mortality. In light of the success of other transcatheter-based valve interventions, transcatheter tricuspid therapy has recently seen exponential use both clinically and in innovation. Given the rapid development of many tricuspid systems and multiple on-going clinical trials, the aim of this review is to highlight the current state of transcatheter tricuspid therapeutics and to provide an up-to-date view of their clinical use, outcomes and future directions.

Update on Transcatheter Tricuspid Valve Replacement Therapies.

Project description:Severe tricuspid regurgitation is relatively common, especially in the elderly, and portends poor survival. Neither medical therapy nor conventional surgery is efficacious for most patients. In contrast, transcatheter tricuspid valve interventions are showing promise to improve quality of life and mortality. Although there is more clinical experience with transcatheter tricuspid valve repair, there are many patients for which repair is either not possible or cannot optimally reduce the severity of tricuspid regurgitation. Transcatheter tricuspid valve replacement is rapidly emerging and may ultimately become the preferred treatment option. In this review, we discuss transcatheter tricuspid valve replacement, analyze the devices in development and in clinical trials, and highlight the advantages and drawbacks of transcatheter tricuspid valve replacement vs. repair.

Long-term outcome after coil embolization of cavernous sinus arteriovenous fistulas.

Project description:Background and purposeCranial nerve palsies are regularly observed in patients with arteriovenous fistulas of the cavernous sinus. The purpose of our study was to determine the long-term clinical outcome-with a special focus on extra-ocular muscular dysfunctions-in patients who had undergone endovascular treatment of a cavernous sinus fistula with detachable coils.Materials and methodsSixteen patients were recalled for an ophthalmoneurologic control examination (mean interval of 4.4 years). The mRS and the EQ-5D questionnaire were used for the description of general outcome. Age, duration of symptoms, character of the fistula (direct, dural), and coil volume were tested to assess their relevance for persistent symptoms.ResultsAll patients displayed complete regression of chemosis, exophthalmus, and pulsating tinnitus with no evidence of recurrences. Oculomotor disturbances persisted in 9 of 13 patients and caused permanent diplopia in 7 patients. In 15 patients a mRS score of 1 or 2 was achieved; however, 7 patients reported some limitations in life quality (EQ-5D). A significant correlation was found between coil volume and persistent diplopia (P = .032) and persistent cranial nerve VI paresis (P = .037).ConclusionsCoil embolization of the cavernous sinus led to durable closure of AVF and reliable regression of acute symptoms. However, long-term follow-up showed a 44% rate of persistent cranial nerve deficits with disturbances of oculomotor and visual functions. This may be explained by the underlying fistula size itself and/or the space-occupying effect of the coils. As neuro-ophthalmologic outcome is crucial for control of therapeutic success, patients should be routinely examined by ophthalmologists.
