Classical symptomatic low-flow, low-gradient (LFLG) severe aortic stenosis is associated with low survival rates at 3 years (<50%). However, in the medium term and with surgery, those rates improve (although mortality rates are 6%-30%, depending on the series). In patients without contractile reserve, surgical mortality is higher. Patient evolution in TAVR is still mostly unclear. …
Diastolic Dysfunction Should Be Considered in TAVR
Aortic stenosis increases afterload creating hypertrophy as a compensation mechanism to maintain minute volume. This leads to left ventricular diastolic dysfunction (LVDD). More than half of patients presenting aortic stenosis have LVDD and myocardial fibrosis, which is a mortality predictor in surgery. At present, there is contradicting evidence in TAVR. The study looked…
Delayed Coronary Obstruction After TAVR: A Complication We Had Not Considered
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…
NOTION: 5-Year Outcomes of TAVR vs. Surgery in Low-Risk Patients are Promising
At 5 years, there were no differences in all-cause death, stroke, acute myocardial infarction, or all of these combined between low-risk, elderly patients who underwent transcatheter aortic valve replacement (TAVR) or conventional surgery. Taking into account reports from previous years, these results are not at all surprising. NOTION enrolled an all-comers population that was 70 years old…
Permanent Pacemaker: still TAVR’s Aquila’s Heel
TAVR has shown benefits in high risk patients (prohibitive) and in intermediate risk patients, but the need for permanent pacemaker implantation (PPI) continues to be a soft spot (especially in younger patients) given time of use, eventual replacement and associated complications. Even though there is little information on PPI, pacemakers are not associated with higher mortality, but they…
Next-Day Discharge after TAVR: Is It Viable?
Next-day discharge after transfemoral transcatheter aortic valve replacement (TAVR) might be viable, with no major complications at 30 days or one year, compared against patients with longer hospital stay. We only have to consider a few factors that will help us choose the most adequate patients for this modality without compromising safety. One of the main advantages…
Red Light for TAVR in Low Surgical Risk Patients
A new study raises an alarm against expanding transcatheter aortic valve replacement (TAVR) procedures to low surgical risk patients, since 2 year mortality seems higher in these patients with TAVR, compared to conventional surgery. This study will soon be published in Catheter Cardiovasc Interv. Expanding TAVR to low risk patients might involve risks we have not…
Is Emergency Cardiac Surgery Necessary in TAVR?
Life-threatening complications that require surgery during TAVR are infrequent. The proportion was originally thought to be between 1% and 2%. However, we now know that it is lower, even though we do not know how frequent it is or what are its most common causes. Its evolution, both in the short and in the long…
Coronary Disease Works as a 30-Day Predictor in TAVR
The association between aortic stenosis and coronary disease is common, since both conditions share pathogenesis, risk factors, and symptoms. Transcatheter aortic valve replacement (TAVR) is currently indicated for high-risk and inoperable patients. It also appears as a valid alternative for the treatment of intermediate-risk patients, and it could soon be indicated for low-risk patients. Coronary…
Leading Manufacturer of Balloon-Expandable Valves Launches Self-Expanding Device
Edwards Lifesciences could have been satisfied after the success of the PARTNER trials and the improvements to its balloon-expandable valve (mainly as regards the delivery system profile and paravalvular leak reduction) in its last model, SAPIEN 3. However, it was not. The company decided to keep going, developing a valve that is radically different from its…
