Aortic valve regurgitation in patients undergoing LVAD implantation is a significant complication which occurs in up to 10% of patients in the INTERMACS database. Patients who have aortic valve regurgitation at the time of implant have been handled by several methods, including aortic valve leaflets approximation, to aortic valve replacement or even valve closure. We report a case where we used HAART Ring to repair a regurgitant aortic valve during LAVD implant for destination therapy.

AbstractTo assess the association between the aortic root diameter in HLA-B27 positive (+) and HLA-B27 negative (−) ankylosing spondylitis (AS) patients from the CARDAS cohort. The CARDAS study is a cross-sectional study in AS patients between 50 and 75 years who were recruited from a large rheumatology outpatient clinic. Patients underwent cardiovascular screening including echocardiography, with 2D, spectral, and color flow Doppler measurements. The aortic root was measured at sinuses of Valsalva during diastole. The aortic root diameter was adjusted for body surface area (BSA) (aortic root index, cm/m2). 193 Consecutive AS patients were included of whom 158 (82%) were HLA-B27 positive. The aortic root index was significantly higher in HLA-B27 + patients compared to HLA-B27− patients, respectively, 1.76 cm ± 0.21 vs. 1.64 cm ± 0.14, p < 0.001. No difference was seen in the prevalence of aortic valve regurgitation (AVR), p = 0.8. Regression analysis showed a significant association between HLA-B27 and aortic root index corrected for age, sex and cardiovascular risk factors (β 0.091, 95% CI 0.015–0.168, p = 0.02). Especially, male HLA-B27 + patients had a significantly increased aortic root index compared to male HLA-B27− AS patients, respectively, 1.76 cm (1.63–1.88) and 1.59 cm (1.53–1.68), p < 0.001. We found an increased aortic root index in elderly HLA-B27 + AS patients compared to HLA-B27− AS patients, especially in male patients. No difference was seen in the prevalence of AVR. However, as AVR can be progressive, echocardiographic monitoring in elderly male HLA-B27 + AS might be considered.

AbstractPatients with aortic incompetence frequently present with anatomical and pathological challenges such as elliptical dilated annulus, dilated aortic root, dilated ascending aorta, and with no calcification in the aortic cusps or annulus. Patients are commonly in graver clinical condition as a result of a long silent clinical course before overt congestive heart failure. All of the above make transcatheter therapies for native aortic valve regurgitation more challenging with poorer outcomes, escalating the risk of insufficient anchoring, prosthesis migration, and residual paravalvular leak compared with current transcatheter aortic valve replacement (TAVR) outcomes for aortic stenosis. There is a need for specialized TAVR devices to address this complex pathology. Surgical aortic valve replacement is the current treatment option and the gold standard for patients with aortic incompetence (AR). Currently, the specific off-label indication for TAVR in pure native AR could be a feasible and reasonable option, as a compassionate treatment is limited to inoperable patients and agreed on by the heart team.

Abstract Background The prevalence of bicuspid aortic valve (BAV) in newborns is 0.8%. BAV is associated with an increased risk of aortic valve dysfunction and aortopathy. Aortopathy with increased aortic diameters has recently been reported in newborns with BAV. As most patients with BAV are diagnosed in adulthood the development of BAV and associated aortopathy during early years of life is not well described. Purpose The purpose of the study was to assess changes in aortic valve function and aortic dimensions at two to four years of age in children diagnosed with BAV neonatally. Methods Children with BAV were included from a population-based cohort study, in which newborns (n≈25,000) underwent standardized transthoracic echocardiography (TTE). Follow-up TTE was performed and analyzed according to established guidelines. Neonatal (baseline) and follow-up data were compared. Diameters were indexed to body surface area (BSA). Z-scores were calculated using formulas from the Pediatric Heart Network Echocardiogram Database. Results At follow-up 101 newborns with BAV (mean age 2 years 5 months, SD 11 months), 75% male) were examined from May 2019 to April 2021. From baseline to follow-up there was an increase in the BSA-adjusted diameter of the aortic valve annulus (z-score −0.19 at baseline vs 0.95 at follow up, p&lt;0.001), and of the sino-tubular junction (z-score 0.16 at baseline vs 0.43 at follow up, p&lt;0.05). Conversely, there was a decrease in the Z-score for the diameter measured 1 cm from the valve annulus (z-score 1.31 at baseline vs 0.68 at follow up, p&lt;0.001) and at the widest point of the visualized ascending aorta (z-score 2.44 at baseline vs 1.45 at follow up, p&lt;0.001). There was no significant change in the diameter of the sinus of Valsalva (z-score 0.83 at baseline vs 0.80 at follow up, p=0.92). The number of children with at least one aortic z-score &gt;3 was 31 (30.6%) at baseline and 17 (17.8%) at follow up. At baseline mild aortic valve regurgitation was observed in 18 children (17.8%) and in 23 children at follow up (23%). Mean maximum systolic velocities across the aortic valve were 1.03 m/s at baseline (SD 0.24) and 1.11 m/s at follow up (SD 0.27), p&lt;0.05. Aortic stenosis, defined as flow velocity &gt;2.5 m/s was seen in one child both at baseline and at follow-up. Conclusion In children diagnosed with BAV neonatally, re-examination at the age of 2.5 years showed significant increases in the diameter of the aortic valve annulus and the sino-tubular junction, but a significant decrease in the diameter of the ascending aorta. The maximum blood flow velocity across the aortic valve increased and more children had developed mild aortic valve regurgitation. Thus, the bicuspid aortic valve and the associated aortopathy seem to undergo remodeling during early childhood. FUNDunding Acknowledgement Type of funding sources: Foundation.

Background: Failure of the native aortic valve and degenerative anatomy of ascending aorta in patients with previous Tirone-David operation may represent a clinical challenge, because sometimes the risk of reoperation is prohibitive.Case: We described the case of a patient suffering from severe aortic valve regurgitation and pseudoaneurysm of the aortic arch, 6 years after cardiac surgery operation. The aim of this clinical case was to assess if the complex anatomy of aortic pseudoaneurysm and aortic root geometry can be accurately reproduced from contrast-enhanced computed tomography scan into a three-dimensional (3D) printed model. Based on this procedural method, with the aid of transesophageal 3D ultrasound, we efficaciously treated the patient percutaneously with a combination of transcatheter occluder device plus microcoil embolization and transfemoral aortic valve implantation. The patient was free from complications and the need to redo cardiac surgery.Conclusion: To the best of our knowledge, this is the first description of two simultaneous complications and their staged treatment in a patient with previous aortic valve-sparing operation. This is a useful report in a single 3D model applying such specific technology to these two simultaneous clinical settings.

A quadricuspid aortic valve is a very rare congenital heart condition that can present as aortic regurgitation in the 5th and 6th decade of life. The following case report will describe a patient who presented with symptoms of severe aortic regurgitation and was found to have a quadricuspid aortic valve on echocardiography. The case will describe the clinical manifestations in which the patient presented and the subsequent diagnosis of the quadricuspid aortic valve. The rationale for the surgical approach will also be discussed, along with the patient’s clinical response.

A 79-year-old man was referred for severe cardiac decompensation. Chest radiography showed severe pulmonary edema, and transesophageal echocardiography revealed a large quantity of vegetation on all aortic valve leaflets with severe aortic valve regurgitation, heterogeneous cavities adjacent to the aortic annulus, and ventricular septal rupture. We performed thorough and extensive debridement of the aortic root; including the infected ventricular septum, reconstructed the ventricular septum and aortic root using autologous and bovine pericardial patches; and placed a bioprosthetic stented valve. The patient was discharged without any complications, and without recurrence of the endocarditis in the four years post-surgery.

The combination of aortic valve regurgitation, rheumatoid aortitis, and subaortic stenosis is not frequent in patients with rheumatoid arthritis. Moreover, the surgical treatment of these entities may be challenging with non-adequate results. We report a case of a patient with severe aortic valve regurgitation, inaccessible aortic root secondary to rheumatoid aortitis, and severe subaortic stenosis initially treated by aortic valve replacement. We reoperated the patient due to acute prosthetic valve failure performing an aortic valve reconstruction using bovine pericardium and Ozaki’s technique with good outcomes.
