Aortic valve disease occurs when the valve that acts like a gateway between the heart and the aorta does not work properly. (uclahealth.org)
A new valve is placed in the ascending aorta to restore aortic valve function. (uclahealth.org)
most aortic aneurysms (AAs) occur in the abdominal aorta and thus are termed abdominal aortic aneurysms (AAAs). (medscape.com)
Aneurysmal degeneration that occurs in the thoracic aorta is termed a thoracic aortic aneurysm (TAA). (medscape.com)
Aneurysms that involve the ascending aorta may extend as far proximally as the aortic annulus and as far distally as the innominate artery, whereas descending thoracic aneurysms begin beyond the left subclavian artery. (medscape.com)
[ 6 ] They successfully replaced the ascending aorta with an aortic allograft. (medscape.com)
Aortic stenosis causes increasing resistance against the ejection of blood from the left ventricle towards the aorta. (inbit.gr)
Blood flows out of your heart and into the aorta through a valve. (medlineplus.gov)

An adjusted analysis was performed to compare the early clinical safety outcome according to the Valve Academic Research Consortium-2 deﬁnition. (123dok.net)
Early Outcome in Patients Requiring Conversion to General Anesthesia During Transfemoral Transcatheter Aortic Valve Implantation. (stanford.edu)
So far, the outcome of patients undergoing unplanned periprocedural conversion from CS to general anesthesia has not been investigated. (stanford.edu)
The outcome of the patient appears only to be related to the patient's pre-operative STS score. (frontiersin.org)
Nonetheless, 39% of patients had a poor outcome after TAVR. (stanford.edu)

TAVR is a novel procedure which is well tolerated by many patients for whom an open heart surgery is considered to be risky. (yashodahospitals.com)
TAVR is indicated for a patient with intermediate or high-risk for complications related to surgical aortic valve replacement. (yashodahospitals.com)
How is TAVR different from surgical valve replacement? (yashodahospitals.com)
In patients who are deemed too high risk for open heart surgery, TAVR significantly reduces the rates of death and cardiac symptoms. (wikipedia.org)
Until about 2017 TAVR was not routinely recommended for low-risk patients in favor of surgical aortic valve replacement, however it is increasingly being offered to intermediate risk patients, based on studies finding that it is not inferior to surgical aortic valve replacement. (wikipedia.org)
Transapical TAVR is reserved for patients for whom other approaches are not feasible: an evidence-based BMJ Rapid Recommendation made a strong recommendation against transapical TAVR in people who are also candidates for either transfemoral TAVR or surgery. (wikipedia.org)
The rationale for age-based recommendations is that surgical aortic valve replacements are known to be durable long-term (average of durability of 20 years), so people with longer life expectancy would be at higher risk if TAVR durability is worse than surgery. (wikipedia.org)
In the 2017 AHA/ACC focused update, evidence of benefit and noninferiority extended the use of TAVR to intermediate-risk patients. (acpjournals.org)
More recent studies suggest potential benefit to low-risk patients, although no published guidelines yet recommend the use of TAVR for this population. (acpjournals.org)
Although TAVR has less than 10-year experience with valve durability, it has lower or noninferior primary end points, such as mortality and stroke, and fewer periprocedural complications among anatomically permissive patients. (acpjournals.org)
Results from the PARTNER 2, Cohort A trial showed that death or disabling stroke at 2 years-the trial's primary endpoint-were not significantly different for patients randomized to TAVR using the Sapien XT (Edwards Lifesciences) or open-heart surgery. (tctmd.com)
With this second-generation valve, TAVR, certainly from a statistical standpoint was noninferior [to surgery], and in every one of the analyses, the point estimate favored TAVR vs surgery," coprincipal investigator Martin Leon, MD ( NewYork-Presbyterian/ Columbia University, New York, NY), observed. (tctmd.com)
All the same, "in patients who are candidates for transfemoral access, TAVR may result in additional clinical advantages," Smith noted. (tctmd.com)
No difference in the primary endpoint was seen between patients treated surgically and those who underwent a transthoracic TAVR procedure. (tctmd.com)
Questioned about this point during the late-breaking clinical trial session, Smith commented: "My own guess is that, as time goes on, there will be still be some patients who can't have transfemoral TAVR and shouldn't have surgery and still need some other access route to have TAVR. (tctmd.com)
A biological valve is used for TAVR. (medlineplus.gov)
TAVR is used for people with severe aortic stenosis who aren't healthy enough to have open chest surgery to replace a valve . (medlineplus.gov)
The findings reinforce the data presented at ACC 2016 from PARTNER 2A , which showed noninferiority for TAVR using the Sapien XT valve (Edwards Lifesciences). (medscape.com)
At 30 days, TAVR had significantly less acute kidney injury stage 2 or 3 (1.7% vs 4.4%), atrial fibrillation (12.9% vs 43.4%), any stroke (3.4% vs 5.6%), need for transfusion (0 units 58.9% vs 87.5%), and superior quality of life, "all the things your patients want," Reardon said. (medscape.com)
This is important for patients in terms of their ability to exercise, Reardon explained and told heart wire that while not presented, 6-minute-walk scores were better in the TAVR group at 30 days and remained better at 1 year. (medscape.com)

The management of this subset of patients is particularly challenging because the AVA-gradient discrepancy raises uncertainty about the actual stenosis severity and thus about the indication for aortic valve replacement (AVR) if the patient has symptoms and/or left ventricular (LV) systolic dysfunction. (omicsdi.org)
First, is there an indication for aortic valve replacement (AVR)? (ecrjournal.com)

Two-dimensional transthoracic echocardiography can confirm the clinical diagnosis of aortic stenosis and provide specific data on LV function. (medscape.com)

Early data suggest that stroke rates are even lower with the lower-profile Sapien 3 device (Edwards Lifesciences), which is the subject of another late-breaking clinical trial presentation tomorrow, also in intermediate-risk patients. (tctmd.com)
One of the most important clinical challenges in these three categories of patients with LG AS (classical LF-LG, paradoxical LF-LG, and NF-LG) is to differentiate a true-severe AS that generally benefits from AVR vs. a pseudo-severe AS that should be managed conservatively. (omicsdi.org)
