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...
St elevation acute coronary syndromes are typically caused by thrombotic obstruction of a coronary artery due to ruptured atherosclerosis plaque. However, there is a significant number of patients with similar clinical presentations but no evidence of obstructive coronary artery disease (CAD).

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...
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...
Mitral paravalvular leaks are relatively common after surgical mitral replacement, with an incidence of 7%-17%. Most of these are subclinical leaks, a mere echocardiogram finding, but about 3% of patients can develop heart failure, hemolysis, or a combination of both, thus requiring a new intervention. For symptomatic patients, new surgery has been the traditional treatment...

Currently, some small observational studies and a meta-analysis suggest that women experience more short-term complications after TAVR (due to higher rates of bleeding, vascular complications, and stroke), as well as less 1-year mortality. However, results are still conflicting. This work analyzed 17 studies including 8 different registries, with a total 23,303 women and 23,885 men....
The Transcatheter mitral valve replacement has been established as gold standard for patients with intermediate or high risk severe aortic stenosis. The supporting evidence was initially gathered with one or two safe and effective devices that worked really well, so that later on prosthetic valves multiplied, for competing companies wanted their share of the market. However,...
Courtesy of Dr. Carlos Fava. Peripheral vascular diseases (PVD) present the same risk factors as aortic stenosis. In consequence, these disorders usually coexist. The frequency and impact of their various stages on patients undergoing TAVR is yet to be thoroughly assessed. Read also: “Peripheral Vascular Disease Is Associated to More Events in TAVR”. This study analyzed...
Courtesy of Dr. Carlos Fava. Spontaneous Coronary artery dissection (SCAD) was first described in 1931 and, even though its prevalence according to different studies is roughly between 0.07% and 1.1%, it is more frequent in women and is associated to acute coronary syndrome and sudden death. The study looked at 752,352 women presenting acute myocardial infarction (AMI)...
The main advantage of transcatheter aortic valve replacement (TAVR) has always been its less invasive nature, compared against surgery. Many of the advances in this technique revolve around making it even less invasive, increasing the gap between the two. The kind of anesthesia has been one of these many advances. There are several reports (in general from...
