Circumferential type A aortic dissection and intimal intussusception of the aorta causing severe aortic regurgitation
and obstruction of the left main coronary artery.
Overall survival was 90 percent, and there was no moderate or severe aortic regurgitation
. Even with mechanical valves, regurgitation can be a problem.
This technology, the company claims, is the first in class designed to treat aortic stenosis by replacing the patient's native aortic valve, while minimizing the degree and frequency of aortic regurgitation
. The fully repositionable and retrievable device is designed to treat patients with severe aortic stenosis who are at extreme surgical risk, while reducing the risk of post-procedural aortic regurgitation
Decreased or absent peripheral pulses, aortic regurgitation
, arterial bruits, and both systemic and pulmonary hypertension are common.
A preoperative transthoracic echocardiogram confirmed the severe dilated cardiomyopathy and aortic valve disease (area by continuity equation 1 cm (2); peak gradient 55 mmHg in the presence of a left ventricular ejection fraction of 15 to 20%), and moderate aortic regurgitation
* Rheumatic AS: Infrequently seen in USA, often coexists with aortic regurgitation
(AR) and mitral valve disease, Isolated AS suggests non rheumatic etiology.
"You cannot do this with calcified valves." They have to be flexible so that the balloon procedure does not cause torrential aortic regurgitation
Transthoracic echocardiography was then done which showed mild aortic stenosis and trace aortic regurgitation
, mildly dilated left atrium with Grade IA left ventricular diastolic dysfunction.
Transthoracic echocardiogram (TTE) confirmed severe AS (mean gradient 40 mmHg; aortic valve area 0.8 [cm.sup.2]), concomitant moderate aortic regurgitation
, and preserved left ventricular function (ejection fraction 55%).
Group-A comprised of nineteen (37%) patients who neither had aortic structural nor functional abnormality while GroupB had six (11.7%) patients, having aortic valve cusp prolapse without aortic regurgitation
. Group-C and Group-D consists of seventeen (33.3%) and nine (17.6%) patients respectively depending upon degree of aortic regurgitation
is the common aortic valvular lesion seen in rheumatic heart disease.
Post valvuloplasty, eight patients (10.6%) patient had some degree of aortic regurgitation
(AR) but none of them required any surgical intervention immediately.
The patient suffered from debilitating heart failure symptoms due to severe aortic regurgitation
and was considered to be at a high risk for open-heart aortic valve replacement surgery due to his condition.
There was mild aortic regurgitation
with an aortic valve area of 2.24 cm [sup]2 .
