The benefits of transcatheter aortic valve replacement (TAVR) for high-risk, prohibitive-risk (class I) or intermediate-risk (class IIa) patients have already been proven, but there is a growing population of patients with a history of myocardial revascularization surgery (MRS) who experience severe aortic stenosis. Decision-making in these cases is anything but simple, mainly due to the presence of...
Delayed coronary obstruction (after TAVR, outside the cath lab) is a rare complication with high mortality rates, not unlike acute obstruction. Cardiologists should be expectant and, upon the slightest suspicion of this complication, patients should be brought back to the cath lab for a coronary angiography. Occlusion immediately after implant release has been well-studied and...
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...
Courtesy of Dr. Carlos Fava. Transcatheter aortic valve implantation has already proven to be beneficial for high-risk and inoperable patients. In that sense, it is also an increasingly frequent solid option for lower-risk patients. However, due to the presence of valve calcifications, it may occasionally be necessary to assess the benefits and risks of valve dilation...
Courtesy of Dr. Agustín Vecchia. Surgery is the treatment of choice for patients with symptomatic aortic insufficiency and/or ventricular dilatation or decreased ventricular function. The broad implementation of transcatheter aortic valve replacement (TAVR) in patients with aortic stenosis, the emergence of new devices, and the experience acquired by operators have brought this treatment to off-label indications such...
Original Title: Transcatheter Aortic Valve Replacement versus Surgical Valve Replacement in Intermediate-Risk Patients: A Propensity Score Analysis. Reference: Vinod H Thourani et al. Lancet Published Online April 3, 2016. Courtesy of Dr. Carlos Fava. The transcatheter Aortic Valve Replacement (TAVI) has shown benefits in high risk patients or inoperable patients, but there is little evidence...
