Transcatheter aortic valve replacement (TAVR) is now the standard of care for patients with symptomatic severe aortic stenosis who are at extreme, high, or intermediate risk for surgery. This multicenter, prospective study (Feasibility of Transcatheter Aortic Valve Replacement in Low-Risk Patients With Symptomatic, Severe Aortic Stenosis) included low-risk patients and was approved by the United...
We are deeply thankful to all interventional physicians who, motivated by their great scientific and educational vocation, presented their works at the “José Gabay” Course. Read the presentations below: Module I: Fundamentals and Basic Elements. Leiva Pons, José Luis. “Vascular Closure Devices. Step by Step.” (Spanish version) García García, Hector. “Current Status of Coronary Intervention:...
Courtesy of Dr. Carlos Fava. Tricuspid regurgitation (TR) has a negative impact in the long run. Several reports have shown that, in high risk inoperable patients, transcatheter edge-to-edge valve repair with MitraClip is feasible, safe and has good results, but there is still a long way to go. The present study looked at 24 consecutive...
Courtesy of Dr. Carlos Fava. Mitral regurgitation accounts for around 25% of valvular diseases and is a strong mortality predictor in heart disease. One of the challenges of this disease is that patients respond favorably to medical treatment for a long time, which makes hard to establish the right time to perform an intervention without...
Courtesy of Dr. Carlos Fava. Aortic stenosis with cardiac failure or cardiogenic shock involves high mortality risk at short term. Surgery in these conditions is often unsafe, which leaves us with valvuloplasty, but only as a bridge to some other procedure, seeing as it is effective only for a short time. Few studies have looked into patients undergoing...
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...
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...
Courtesy of Dr. Carlos Fava. The current recommendation for aortic valve replacement is based on stenosis severity based on valvular criteria (mean transvalvular gradient, peak aortic velocity and valve index area) and the presence of symptoms, in addition to comorbidities, mainly for risk stratification. However, ventricular damage and/or its effect on cardiovascular hemodynamics are not regarded...
Most literature, old and recent, associates carotid artery stenting with a higher rate of stroke (although minor) when compared with carotid endarterectomy during the acute period. However, 30-day outcomes of angioplasty and surgery are comparable. Many technical advancements, including new stent designs and different cerebral protection mechanisms, have improved the outcomes of angioplasty in clinical...
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...
