Method Randomized selection of 100 patients, underwent aortic valve replacement with a single type of bio-prosthesis (Medtronic Mosaic) for pure aortic stenosis. The study population showed that, 25/100 (25%) patients had prosthesis-patient mismatch of a moderate degree (indexed effective orifice area (IEOA) from 0.65 cm2/m2 0.85 cm2/m2). The effect of prosthesis-patient mismatch on the postope...

Prosthesis-patient mismatch PPM was first introduced by Rahimtoola in 1978 as the situation in which the effective prosthetic valve area, after process refinery pdf insertion into.Prevalence and Long-Term Outcome of Aortic Prosthesis-Patient Mismatch in Patients With Paradoxical. Strategy to avoid patient-prosthesis mismatch: aortic root enlargement Asian Cardiovascular process liptak pdf and T...

COMPLETE valvular replacement is the only feasible method for treatment of many cases of aortic valvular disease. While the long-term results will not be known for some time, the prognosis without operation, in carefully selected patients, is so poor as to justify this approach. Our total experience, consisting of a group of 16 such patients undergoing aortic replacement with the ballvalve pros...

We describe a 74-year-old male who underwent open stent repair for an infrarenal abdominal aortic aneurysm with a severely calcified aortic neck. The stent graft was constructed by covering a 50-mm long Gianturco Z stent (diameter: 20 mm) with a Dacron prosthesis (diameter: 20 mm). The stented Dacron graft was inserted into the calcified aortic neck, was then sutured to the trimmed aneurysmal w...

1269 We appreciate the interest of Siondalski et al. [1] and his group beside numerous other international groups in working on autologous aortic valve prosthesis. We experienced tremendous interest, especially in countries where patients need a priceless and reliable bioprosthesis without the need for anticoagulation and with advantageous hemodynamics especially in the smaller sizes. Siondalsk...

The authors report the case of a 66-year-old male patient diagnosed with a pseudoaneurysm of the distal aorto-aortic anastomosis treated with the inner tubing technique. The patient had been operated on 1 year before when he had an aortic prosthesis implanted as treatment for a ruptured abdominal aortic aneurysm. The inner tubing technique was developed to facilitate the treatment in bifurcated...

AIM The mains topics of this work are the incidence of patient-prosthesis mismatch and the influence in the early results of isolated aortic valve surgery. METHODS In 193 patients isolated aortic valve surgery was performed. The study population was divided in three subgroups: 20 patients with severe, 131 patients with moderate and 42 patients without patient-prosthesis mismatch. The indexed ...

AIMS Aortic regurgitation after transcatheter aortic valve implantation (TAVI) is one of the most frequent complications. However, the underlying mechanisms of this complication remain unclear. The present evaluation studied the anatomic and morphological features of the aortic valve annulus that may predict aortic regurgitation after TAVI. METHODS AND RESULTS In 53 patients with severe aorti...

secondary aortoenteric fistula (saf) is an uncommon but very important complication of abdominal aortic reconstruction. the complication often occurs months to years after aortic surgery. the clinical manifestation of the aortoenteric fistula is always upper gastrointestinal bleeding. treatment of the disease is early surgical intervention. if operative treatment is not performed promptly, the ...

OBJECTIVES To compare aortic annulus diameters obtained by 3D transesophageal echocardiography (TEE) with 2D-TEE and the impact on prosthesis size selection in transcatheter aortic valve implantation (TAVI). BACKGROUND In TAVI the aortic annulus diameter determines prosthesis size. The ideal modality for annulus assessment has not been defined yet. METHODS Annulus diameters in 2D-TEE (long-...
