Aortic Valve Prosthesis

The authors present a case of thrombosis on the St. Jude Medical 19 aortic valve prosthesis. The diagnosis was confirmed by transthoracic and transoesofageal echocardiography, cardiac fluoroscopy revealed restricted movement of the aortic valve prosthesis leaflet. Thrombolytic therapy was complicated with brain embolism that was successfully percutaneously removed from the cerebral artery by the mechanical device. The patient has fully recovered without any neurological residual symptoms. This case report should be instructive to other clinicians who encounter the same complications after thrombolytic treatment.

Aortic Valve Prosthesis

A 64 years old male was submitted to the surgical substitution of a deteriorated biological aortic valve prosthesis with a new Hancock II biological prosthesis. The implantation was not followed by an anticoagulation or antiaggregation therapy. Two months later he was checked at our Institution because he complained symptoms and developed echocardiographic indexes suggestive of an aortic prosthesis obstruction by a clot. Both symptoms and the echocardiographic indexes of prosthesis obstruction faded away after giving warfarin; they arose again when the anticoagulation therapy was stopped and was replaced by aspirin. The following permanent use of warfarin normalized both clinic and echocardiographic aspects. The present case report underlines the utility of early controls after a biological prosthesis, yet aortic, implantation, when it is not followed by an anticoagulant therapy, also in subjects free from thrombosis high risk factors.

We are presenting a case report of failed valve-in-valve treatment of severe aortic stenosis. A control ultrasonography after TAVI implantation revealed a severe aortic regurgitation of the graft which was subsequently unresolved with postimplantation dilatation. Second TAVI was implanted with cranial dislocation to the aortic root. Patient underwent a CT examination to clarify the TAVI in TAVI position. Patient underwent a surgical resection of TAVI with implantation of biological aortic valve prosthesis. In situations where TAVI treatment fails or is complicated beyond the possibility of endovascular repair, surgical intervention despite its higher risks is the preferred choice.

Blood Flow Velocities

<strong>Background</strong>: Severe aortic valve stenosis is associated with high resting and reduced hyperemic coronary blood flow. Coronary blood flow increases after aortic valve replacement (AVR); however, the increase depends on the type of prosthesis used. The present study investigates the influence of type of aortic valve prosthesis on coronary blood flow velocity.<br /><strong>Methods</strong>: The blood flow velocity in the left anterior descending coronary artery (LAD) and the right coronary artery (RCA) was measured intraoperatively before and after AVR with a stentless bioprosthesis (Sorin Freedom Solo; n = 11) or a bileaflet mechanical prosthesis (St. Jude Medical Regent; n = 11). Measurements were made with an X-Plore epicardial Doppler probe (Medistim, Oslo, Norway) following induction of hyperemia with an adenosine infusion. Preoperative and postoperative echocardiography evaluations were used to assess valvular and ventricular function. Velocity time integrals (VTI) were measured from the Doppler signals and used to calculate the proportion of systolic VTI (SF), diastolic VTI (DF), and normalized systolic coronary blood flow velocities (NSF) and normalized diastolic coronary blood flow velocities (NDF).<br /><strong>Results</strong>: The systolic proportion of the LAD VTI increased after AVR with the St. Jude Medical Regent prosthesis, which produced higher LAD SF and NSF values than the Sorin Freedom Solo prosthesis (SF, 0.41 ± 0.09 versus 0.29 ± 0.13 [P = .04]; NSF, 0.88 ± 0.24 versus 0.55 ± 0.17 [P = .01]). No significant changes in the LAD velocity profile were noted after valve replacement with the Sorin Freedom Solo, despite a significant reduction in transvalvular gradient and an increase in the effective orifice area. AVR had no effect on the RCA flow velocity profile.<br /><strong>Conclusion</strong>: The coronary flow velocity profile in the LAD was significantly influenced by the type of aortic valve prosthesis used. The differences in the LAD velocity profile probably reflect differences in valve design and the systolic transvalvular flow pattern.
