Courtesy of Dr. Carlos Fava. The balloon aortic valvuloplasty (BAV) was introduced by Dr. Cribier in 1986. However, given its poor results, soon after it fell into disuse. With the introduction of TAVR, it saw a revival as bridge for another intervention, even though it is still resisted in many places. The present study…
Early Endarterectomy Seems Superior to Carotid Stenting in Symptomatic Patients
Patients with symptomatic stenosis of the internal carotid artery benefit from early intervention. The challenge lies in what intervention to choose. Most studies comparing endarterectomy to carotid stenting are fairly heterogeneous as regards timing of intervention. This element is key to comparing between procedures, since there is no doubt timing will directly affect results. …
Amplatzer and Figulla Devices Prove to Be Safe for Percutaneous Patent Foramen Ovale Closure
Courtesy of Dr. José Álvarez. In patients with presumed paradoxical embolism through a patent foramen ovale (PFO) who are at high risk of recurrent thromboembolic events, percutaneous PFO closure is an alternative to pharmacological treatment. This closure has been shown to be safe and feasible with different devices including various technologies based on an umbrella,…
[SURTAVI] Sub-study of neurological events: more evidence in favor of TAVR
Courtesy of SBHCI. The occurrence of a periprocedural neurological events is associated to an increased risk of death and morbidity at long term, both for transcatheter aortic valve replacement (TAVR) and for surgery. The SURTAVI study, recently presented at the ACC meeting and simultaneously published by NEJM, showed that TAVR with self-expandable CoreValve or Evolut…
Cerebral protection during TAVI still offers weak evidence, but there is hope
Silent ischemic embolic lesions are common after transcatheter aortic valve implantation (TAVI). The use of cerebral protection devices might reduce the occurrence of these embolic lesions. Multiple studies with different devices, designs, and outcomes challenge the usefulness of cerebral protection during TAVI. A comprehensive analysis of the literature was necessary to obtain a more…
Carotid stenting or endarterectomy? considering vascular anatomy…
Complex vascular anatomy could increase the risk of periprocedural stroke during carotid artery stenting (CAS). However, no randomize study has provided evidence showing this potential difficulty should inform the choice between carotid stenting and endarterectomy. This study included 184 patients with symptomatic lesions of the internal carotid randomized to CAS vs. endarterectomy in the context…
Endarterectomy or Carotid Artery Stenting? A Question That Still Generates Studies
There have been several studies offering contradictory data on the relative effectiveness of carotid artery stenting and carotid artery endarterectomy for the prevention of stroke due to carotid artery stenosis. The authors of this study performed a meta-analysis assessing the efficacy of these techniques, given recently published clinical trial data. They selected randomized…
Tricuspid valve repair with the MitraClip technique
Current surgical and medical treatment options for severe tricuspid regurgitation are extremely limited. However, this historically forgotten valve seems to have the option of transcatheter repair, nowadays. This observational study assessed the safety and feasibility of the MitraClip system for patients with severe chronic tricuspid regurgitation. All patients presented severe tricuspid regurgitation and…
Closing off the Appendage While Performing Cardiac Surgery Results in a Reduction in Risk of Embolic Stroke
Closing off the left appendage as an add-on procedure while performing other cardiac surgery in patients with atrial fibrillation resulted in a reduction in risk of embolic stroke of nearly 40% over 12 months, according to an analysis carried out on the Society of Thoracic Surgeons (STS) database. Patients who had surgical appendage occlusion had…
Cerebral Protection in TAVR: Does It Improve Cognitive Function?
Neurological complications during transcatheter aortic valve replacement (TAVR) may be reduced with cerebral protection devices; this study was designed to explore that hypothesis. The study enrolled 363 patients undergoing TAVR in 19 sites and divided them in three arms: a safety arm (n = 123), a device imaging arm (n = 121), and a non-device imaging arm (n = 119). The…
