Courtesy of Dr. Carlos Fava. The incidence of unprotected left main severe stenosis ranges between 4 and 8%, and it’s mostly associated with multivessel disease. The use of left ventricular support devices in high risk unprotected left main PCI is on the rise, but not much information available in this regard. Read also: “Prior assistance…
Small Annulus: Should We Start Choosing the Valve?
Courtesy of Dr. Carlos Fava. A small annulus in patients with Severe Aortic Stenosis is a real challenge, since it is associated with post-surgical prosthesis patient mismatch (PPM), which negatively affects prosthesis duration and evolution. TAVR has become a good alternative strategy, with better hemodynamic profile and lower PPM incidence in this group. The present study included 246…
Tricuspid and Bicuspid Valves Present More Coincidences Than Expected
There is more and more positive evidence that new-generation transcatheter valves, originally designed to treat tricuspid aortic valves, work perfectly fine on bicuspid aortic valves. A comparison of computerized tomography (CT) scans obtained before and after the procedure showed that the most commonly used devices appear to reshape the aortic annulus to the same degree…
Transcatheter Reduction or Surgery for Paravalvular Leak Repair?
Paravalvular leak is complication derived from incomplete sealing between the implanted prosthesis and the native annulus, which occurs in 5% of all patients who undergo mitral valve replacement and 10% of those who undergo transcatheter aortic valve replacement. This is the most frequent non-structural valve dysfunction. While mild leaks can be asymptomatic, moderate to severe…
Multivessel Disease and Severe Carotid Stenosis: How to Proceed
Myocardial revascularization surgery (CABG) is the most frequent of all cardiovascular surgeries and is still the gold standard to treat multivessel disease. Between 6 and 8% of these patients present concomitant carotid stenosis and it is associated with increased peri and post procedural stroke rates during and after surgery. To prevent carotid stenosis, either PCI or endarterectomy…
End of Discussion on the Impact of Pacemaker After TAVR?
Transcatheter aortic valve replacement (TAVR) is often associated with conduction abnormalities, which usually end with permanent pacemaker (PPM) implantation in 10-40% of patients. Factors predisposing to PPM after TAVR have been studied in great detail, but their short- and long-term clinical impact is still controversial. Recently, outcomes from a large cohort of patients were…
Early Coronary Angiography in High-Risk Non-ST-Elevation ACS
Coronary angiography is essential for patients admitted with non-ST-elevation acute coronary syndrome, since it allows physicians to confirm the diagnosis, stratify the risk, and define the revascularization and antithrombotic management strategies. There is no doubt that these patients should be studied invasively, but the timing for that is still uncertain. Coronary catheterization within…
With Absorb Out, New Resorbable Scaffolds Have Come onto the Market
By restoring vascular physiology and eliminating the inflammatory focus and the chance of fracture and neo atherosclerosis inherent to DES, bioresorbable scaffolds offer the potential to improve long term outcomes. A number of bioresorbable materials have been tested, mainly polylactic acid, with several limitations that have taken the Absorb bioresorbable scaffold out of the market.…
Frequency and Evolution of Cardiac Perforation in Patients with a History of MRS
Courtesy of Dr. Carlos Fava. Coronary perforation (CP) is a very uncommon event (≈0.4%), associated with severe complications that entail risk of death. It has usually been related to patients with a history of myocardial revascularization surgery (MRS). However, this group usually presents lower rates of cardiac tamponade due to pericardial fibrosis caused by surgery. This…
Endarterectomy vs. Stenting in Asymptomatic Carotid Artery Stenosis
The comparative efficacy and safety of carotid stenting vs. endarterectomy in asymptomatic carotid stenosis patients remains controversial and, what is worse, consensus seems unlikely in the near future. Given the lack of definite evidence, several meta-analyzis and systematic reviews have been produced in an attempt to shed some light on this matter. This study included all…
