Abstract Background Non-bacterial thrombotic endocarditis is characterized by the presence of sterile vegetations on a cardiac valve. We present a case of multi-territory stroke caused by embolism of a non-bacterial thrombotic aortic valve endocarditis, leading to the diagnosis of a prostate adenocarcinoma with bone metastases. Case summary A 66-year-old patient was diagnosed with pulmonary embolism, first attributed to an asymptomatic coronavirus disease 2019 infection. Edoxaban was started, which was discontinued by the patient. Four weeks later, he presented with subacute vertigo and balance disorders. Magnetic resonance imaging showed a multi-territory stroke. A transoesophageal echocardiogram demonstrated a small vegetation on the aortic valve with moderate aortic insufficiency. Blood cultures remained negative. Malignancy screening showed a markedly elevated prostate-specific antigen. Prostate adenocarcinoma was confirmed on biopsy. A positron emission tomography revealed metastatic disease. A diagnosis of non-bacterial thrombotic endocarditis and paraneoplastic pulmonary embolism secondary to prostate cancer was made. Edoxaban was restarted and the patient was referred for treatment of the prostate adenocarcinoma. Follow-up after 5 months showed no evidence of aortic valve vegetations. Discussion Coronavirus disease 2019 in ambulatory patients may be insufficient as a predisposing factor for venous thrombo-embolism and these patients, especially the elderly, should undergo a screening for malignancy. Non-bacterial thrombotic endocarditis is a rare cause of multi-territory stroke. When related to cancer, the prostate can be the primary tumour.

Valve Implantation

Transcatheter aortic valve implantation (TAVI) is now a well-established treatment for severe aortic stenosis. As the number of procedures and indications increase, the age of patients decreases. However, their durability and factors accelerating the process of degeneration are not well-known. The aim of the study was to verify the possibility of using [18F]F-sodium fluoride ([18F]F-NaF) and [18F]F-fluorodeoxyglucose ([18F]F-FDG) positron emission tomography/computed tomography (PET/CT) in assessing the intensity of TAVI valve degenerative processes. In 73 TAVI patients, transthoracic echocardiography (TTE) at initial (before TAVI), baseline (after TAVI), and during follow-up, as well as transesophageal echocardiography (TEE) and PET/CT, were performed using [18F]F-NaF and [18F]F-FDG at the six-month follow-up (FU) visit as a part of a two-year FU period. The morphology of TAVI valve leaflets were assessed in TEE, transvalvular gradients and effective orifice area (EOA) in TTE. Calcium scores and PET tracer activity were counted. We assessed the relationship between [18F]F-NaF and [18F]F-FDG PET/CT uptake at the 6 = month FU with selected indices e.g.,: transvalvular gradient, valve type, EOA and insufficiency grade at following time points after the TAVI procedure. We present the preliminary PET/CT ([18F]F-NaF, [18F]F-FDG) results at the six-month follow-up period as are part of an ongoing study, which will last two years FU. We enrolled 73 TAVI patients with the mean age of 82.49 ± 7.11 years. A significant decrease in transvalvular gradient and increase of effective orifice area and left ventricle ejection fraction were observed. At six months, FU valve thrombosis was diagnosed in four patients, while 7.6% of patients refused planned controls due to the COVID-19 pandemic. We noticed significant correlations between valve types, EOA and transaortic valve gradients, as well as [18F]F-NaF and [18F]F-FDG uptake in PET/CT. PET/CT imaging with the use of [18F]F-FDG and [18F]F-NaF is intended to be feasible, and it practically allows the standardized uptake value (SUV) to differentiate the area containing the TAVI leaflets from the SUV directly adjacent to the ring calcifications and the calcified native leaflets. This could become the seed for future detection and evaluation capabilities regarding the progression of even early degenerative lesions to the TAVI valve, expressed as local leaflet inflammation and microcalcifications.

Aortic Valve Reimplantation

Background —Reimplantation of the native, structurally intact aortic valve within a Dacron tube graft in patients with aortic root aneurysms corrects annular ectasia and dilatation of the sinotubular junction. The durability of this valve repair with respect to the increased mechanical stress on valve cusps has been discussed, is quite controversial, and is yet unknown. Methods and Results —From July 1993 to November 1998, a replacement of the ascending aorta with a repair of the aortic valve was performed in 75 patients (53 men and 22 women aged 50±19 years). Twenty-one patients (28%) had Marfan syndrome, and 11 patients (15%) had an aortic dissection, type Stanford A (6 acute, 5 chronic). In 17 patients (23%), concomitant replacement of the aortic arch was necessary. Clinical and echocardiographic follow-up was performed in 6- to 12-month intervals for a cumulative study period of 137 patient-years. No operative deaths occurred. Two patients (3%) died 5 and 20 months postoperatively. One additional patient experienced a transient ischemic attack within the first postoperative week. Three patients (4%) with progressive aortic insufficiency required aortic valve replacement after 9, 11, and 14 months. All other patients had no or mild aortic insufficiency. The repairs have now remained stable for ≤65 months (mean, 22±20 months). Other valve-related complications did not occur. Conclusions —Our results demonstrate that this type of aortic valve repair achieves excellent results in selected patients. Perfect coaptation of valve cusps during the repair with no or only trace aortic insufficiency at initial echocardiography seems to be essential for durability.

Early Results

Abstract OBJECTIVES Aortic insufficiency (AI) is common in patients with proximal aortic disease, but limited options exist to facilitate aortic valve repair (AVr) in this population. This study reports ‘real-world’ early results of AVr using newly FDA-approved trileaflet and bicuspid geometric annuloplasty rings for patients with AI undergoing proximal aortic repair (PAR) in a single referral centre. METHODS All patients undergoing AVr with a rigid internal geometric annuloplasty ring (n = 47) in conjunction with PAR (ascending +/− root +/− arch) were included. Thirty-six patients underwent AVr with a trileaflet ring, and 11 patients underwent AVr with a bicuspid ring. The rings were implanted in the subannular position, and concomitant leaflet repair was performed if required for cusp prolapse identified after ring placement. RESULTS The median age was 58 years [interquartile range (IQR) 46–70]. PAR included supracoronary ascending replacement in 26 (55%) patients and remodelling valve-sparing root replacement with selective sinus replacement in 20 (42%) patients. Arch replacement was performed in 38 (81%) patients, including hemi-arch in 34 patients and total arch in 4 patients. There was no 30-day/in-hospital mortality. Preoperative AI was 3–4+ in 37 (79%) patients. Forty-one (87%) patients had zero–trace AI on post-repair transoesophageal echocardiography, and 6 patients had 1+ AI. The median early post-repair mean gradient was 13 mmHg (IQR 5–20). Follow-up imaging was available in 32 (68%) patients at a median of 11 months (IQR 10–13) postsurgery. AI was ≤1+ in 97% of patients with 2+ AI in 1 patient. All patients were alive and free from aortic valve reintervention at last follow-up. CONCLUSIONS Early results with geometric rigid internal ring annuloplasty for AVr in patients undergoing PAR appear promising and allow a standardized approach to repair with annular diameter reduction and cusp plication when needed. Longer-term follow-up will be required to ensure the durability of the procedure.

Objective: To assess the predictive role of response on dynamic contrast enhancement on magnetic resonance imaging (DCE-MRI) of visible local lesions in the setting of salvage radiotherapy (sRT) after radical prostatectomy. Methods: All patients referred for sRT for biochemical failure after radical prostatectomy from February 2014 to September 2016 were considered eligible if they had been restaged with DCE-MRI and had been found to have a visible lesion in the prostatic bed, but no distant/nodal disease on choline positron emission tomography (PET)–computed tomography (CT). Eligible patients were contacted during follow-up and offered reimaging with serial DCE-MRI until lesion resolution. Complete response (CR) was defined as the disappearance of the target lesion on DCE-MRI; prostate-specific antigen (PSA) recurrence was defined as a 0.2 ng/mL PSA rise above the nadir. Median follow-up after sRT was 41.5 months (range, 12.1–61.2 months). Results: Fifty-nine patients agreed to undergo repeated DCE-MRI for a total of 64 studied lesions. Overall, 57 lesions (89.1%) showed a CR after 1 (51 patients) or 2 (6 patients) scans, while 7 lesions did not show any change (no response [NR]). At 42 months, no evidence of biochemical disease (bNED) survival was 74.7±6.4% and 64.3±21.0% for patients with CR and NR lesions, respectively (hazard ratio [HR], 3.181; 95% confidence interval [CI], 0.157–64.364; p = 0.451). When only patients treated with sRT without androgen deprivation were selected ( n = 41), bNED survival rates at 42 months were 72.1±8.0% and 0, respectively (HR, 52.830; 95% CI, 1.893–1474.110; p = 0.020). Conclusions: Patients whose lesions disappear during follow-up have a better outcome than those with unchanged lesions after sRT alone.

Day By Day

A 67-year-old woman was admitted with aortic valve endocarditis and aortic wall thickening (AWT). Physical examination and laboratory findings yielded infective endocarditis. Echocardiography revealed several small vegetations on the aortic valve, leading to moderate aortic insufficiency together with a small ventricular septal defect. We also became aware of the AWT on and over the aortic root by transesophageal echocardiography (Figure 1). At the one month follow-up period, we also noticed an abscess formation originating from the AWT, which grew into a mature abscess form, day by day (Figure 2). The aortic valve endocarditis, with destruction of the aortic annulus and abscess formation, in this patient, is considered as a grave condition which, essentially, requires an aggressive combined surgical and medical approach. We would like to intimate here with this patient that AWT needs to be considered seriously important in aortic valve endocarditis and, even if the detected vegetations are small, a close follow-up for a possible abscess formation is essential.

Background: We present our initial institutional experience with transaortic (TAo) transcatheter aortic valve implantation (TAVI) using a self-expanding aortic bioprosthesis. Methods: A total of 106 patients underwent TAo TAVI with Medtronic CoreValve through a small partial upper sternotomy. We focus our analysis on the overall perioperative results, procedural learning curve (first 30 patients), and midterm follow-up outcomes. Results: VARC-2 device success was achieved in 95 patients (89%), and there were no intraoperative deaths. Nine patients (8.4%) required a second valve and conversion to standard surgery was required in 2 patients (1.8%). The final aortic insufficiency was grade 0 in 65 patients (62%) and grade 1 in 39 (37%). Although patients treated in the TAo TAVI learning phase required a significantly longer radiation time and contrast agent use, device success (93.4% versus 88.2%; P = .7) and prostheses hemodynamics were similar. All-cause mortality at 30 days was 12% (13/106). At a median follow-up of 392 days (IQR: 216-494 days) estimated overall 1-year survival was 72%. No significant differences were reported in terms of 30-day and 1-year observed mortality, and estimated 1-year survival in the learning and later phase of TAo TAVI. Conclusion: TAo TAVI can be performed safely even in the very early phase of the learning curve. Although satisfactory results can be achieved from the beginning, a significant reduction in contrast agent use and radiological exposure are expected as the technique is mastered. Good hemodynamics have been documented and should be further improved with modifications achieved in the TAVI self-expandable valves technology.

Abstract Introduction Aortic valve (AV) stenosis is the most common type of congenital left ventricular outflow tract obstruction. Short-term outcomes following balloon aortic valvuloplasty (BAV) including residual aortic stenosis, aortic insufficiency, and procedural complications have been established. The impact of pre-intervention AV characteristics on long-term outcomes has not been well studied. Purpose The aim of this study was to determine the relationship between the initial parameters on baseline echocardiogram and the time to reintervention in children with AV stenosis following BAV. Methods Children from the newborn period to 18 years of age with AV stenosis who underwent BAV from 2004-2012 were included. Patients with aortic insufficiency prior to BAV, complex congenital heart lesions, or less than two accessible follow-up echocardiograms were excluded. Baseline and serial echocardiographic data pertaining to aortic valve and LV size and function was retrospectively collected until December 2017 or until the first reintervention. Time to reintervention or death was evaluated. Results Among the 98 enrolled patients, the median [IQR] age at BAV was 2.8 months [0.2-75]. The median [IQR] duration of follow-up was 6.8 [1.9-9.0] years. Eighty-nine (83%) patients had bicuspid valve morphology and the median [IQR] peak-to-peak catheterization gradient prior to BAV was 49 [34-65] mmHg. The cumulative proportion [95% CI] of reintervention at 5 years following BAV was 33.7% [23.6%, 42.4%]. Primary indications for reintervention were aortic stenosis (57%), aortic insufficiency (14%), or mixed valve disease (30%). Reinterventions included repeat BAV (49%), AV repair (15%), and AV replacement (36%). Increased LVEF at baseline as well as increased mean LV circumferential strain at baseline were associated with decreased risk of reintervention (HR [95% CI] (1 unit increments): 0.974 [0.959-0.989], p &lt; 0.001; 0.939 [0.884-0.997], p = 0.041 respectively). Increased AV annulus z-score was also associated with decreased risk of reintervention (HR [95% CI] (1 unit increments): 0.806 [0.698-0.93], p = 0.003). Conclusions Our results demonstrate that better left ventricular function at baseline, measured by LVEF and mean LV circumferential strain, is associated with a decreased risk of reintervention in neonates and children following BAV. We have also shown that a bigger AV annulus prior to BAV is associated with a decreased risk of reintervention.

Annular Dilation

Aortic valve repair is the preferred approach for the treatment of severe aortic insufficiency (AI), as it allows patients to keep their native aortic valve, thus substantially reducing the risk of prosthesis-related complications. Several studies have documented excellent long-term outcomes of aortic valve repair. The major complication of this operation is AI recurrence, with ensuingneed for reoperation. The surgical experience accumulated over the last two decades has allowed for better understanding of the mechanisms of recurrent AI after aortic valve repair. Herein, we review the current state of knowledge on predictors of aortic valve repair failure. These include unaddressed annular dilation, residual cusp prolapse or retraction, commissural orientation, and use of patch material. This enhanced understanding has led to the development of increasingly refined techniques and improved patient outcomes. Continued follow-up and detailed data collection at the time of surgery, together with three-dimensional echo imaging, will allow further improvements in aortic valve repair.
