INTRODUCTION It is not clear whether associated aortic regurgitation (AR) should be regarded as a risk factor in patients undergoing surgery for severe aortic stenosis (AS). Some authors have suggested that morbidity and mortality are increased in these patients as compared to patients operated for pure AS, whereas others have found no difference of the outcome and prognosis between these groups. OBJECTIVE This study made an attempt to compare the outcome and prognosis following the surgical intervention in patients with severe AS and associated AR and those operated for pure AS, as well as to determine predictive value of clinical, functional and echocardiographic data for the outcome of surgery. METHODS Study population consisted of 122 consecutive patients operated at Dedinje Cardiovascular Institute during 1999 due to severe AS, defined as mean gradient over aortic valve >30 mmHg. The patients were divided into AS group (63 patients with AS without AR or with mild AR) and AS+AR group (59 patients with AS and moderate, severe or very severe AR). The patients were subjected to control clinical, functional and echocardiographic examinations 12 and 18 months following the surgery. RESULTS AND DISCUSSION Preoperatively, the patients in AS group were older and had coronary artery disease more frequently, whereas patients in AS+AR group had higher left ventricular volumes and mass. Preoperative NYHA class, ejection fraction, mean gradient over aortic valve, type and size of the implanted mechanical prosthesis, and the incidence of associated coronary artery bypass surgery were similar between the groups. Similarly, the operative mortality was similar in AS and AS+AR groups (1.6% vs 8.5%, respectively, p=0.11). Twelve months postoperatively, there were no difference of average NYHA class and NYHA class III/ IV between the groups. The patients in AS+AR group were unable to walk >300 meters on 6 minute walk test more frequently than those in AS group (64% vs. 36%, respectively; p=0.043). Eighteen months postoperatively, NYHA class III/IV was found more frequently in AS+AR than in AS group (26% vs. 8%, respectively; p=0.0343). In patients with associated AR, there was no difference of NYHA class with respect to the severity of AR (p=0.815). Multivariate analysis found the association of more than mild AR as an independent predictor of poor functional capacity, irrespective of its severity. CONCLUSION Patients with severe AS and associated AR have poorer postoperative functional capacity as compared to patients operated for pure AS.

Abstract Background Anemia is common in patients (pts) with severe aortic stenosis (AS). Untreated anemia and severe AS are individually associated with the development of heart failure, however data regarding the potential detrimental effect of anemia on left ventricular (LV) function and prognosis in pts with severe AS are controversial. Aim To investigate the impact of anemia on clinical status, echocardiographic parameters and prognosis in pts with severe AS and preserved LV ejection fraction (LVEF). Methods Consecutive patients with severe AS (aortic valve area [AVA] index ≤ 0.6 cm2/m2) and preserved LVEF (>50%) referred to our echocardiography laboratory were prospectively screened. All patients underwent complete clinical examination and comprehensive echocardiography, including speckle tracking-derived measurements of LV and left atrial (LA) strain. Baseline clinical variables included NYHA class, cardiac risk factors, haemoglobin (Hb) level and glomerular filtration rates (GFR, by MDRD formula). The definition of anemia was based on gender-specific cut-off values, as recommended by the WHO (Hb <13.0 g/dL for men, <12.0 g/dL for women). Patients with more than mild aortic regurgitation or mitral valve disease, atrial fibrillation or cardiac pacemakers were excluded. Results The study population included 264 patients (pts) (66 ± 11 yrs, 147 men). Anemia was present in 64 pts (24%). Aortic valve replacement (AVR) was performed in 151 pts. Dividing the study population into 2 groups, according to the presence/absence of anemia, no significant differences were found between groups regarding: age (p = 0.09), body surface area (p = 0.6), LVEF (62 ± 7 vs 63 ± 6%, p = 0.2), LV Global Longitudinal Strain (-15.2 ± 4 vs -14.7 ± 3 %, p = 0.4), LV mass index (p = 0.9), mean aortic gradient (p = 0.2) and indexed AVA (0.40 ± 0.09 vs 0.39 ± 0.09 cm2/m2, p = 0.6), or presence of significant coronary artery disease (p = 0.9). Compared to pts with normal Hb level, in pts with anemia NYHA class (p = 0.03), brain natriuretic peptide values (p = 0.004), lateral E/e’(16.2 ± 6.9 vs 13.7 ± 6.3, p = 0.01) and average E/e" ratio (15.9 ± 5.9 vs 14.1 ± 5.3, p = 0.03), LA volume index (54.3 ± 16.9 vs 45.0 ± 12.1 ml/m2, p < 0.001), and systolic pulmonary artery pressure (38 ± 13 vs 33 ± 8, p = 0.009) were all significantly higher. During a 3–years follow-up 47 pts died. Age, NYHA class, BNP serum level, baseline anemia, LA volume index and systolic pulmonary pressure were associated with all-cause mortality in the whole study group (p < 0.03 for all). In the group of pts who underwent AVR, NYHA class was the only independent predictor of all-cause mortality. Conclusions In our study including pts with severe AS and preserved LVEF, patients with baseline anemia presented worse functional status and LV diastolic dysfunction and increased 3-year all-cause mortality compared to those with normal Hb levels. However, in pts who underwent surgical AVR, there was no impact of baseline anemia on 3-year survival.

Abstract Background Nowadays, in patients with aortic regurgitation (AR), aortic valve surgery is indicated when severe and symptomatic or those with depressed LVEF. However, clinical outcomes of patients with significant aortic regurgitation are not influenced by these factors only. Recently, a new staging system for severe aortic stenosis has been proposed by Généreux on the basis of the extent of anatomic and functional cardiac damage. If this model could be applicable to an unselected significant AR population has not been tested. Purpose The aim of our study was to evaluate the prevalence of the different stages of extra-aortic valvular cardiac damage by the application of Généreux staging and its impact on prognosis in a large, real world cohort of significant AR patients. Methods This study retrospectively analysed the clinical, Doppler echocardiographic and outcome data in patients with grade III or greater AR between January 2014 and September 2019. According to the extent of cardiac damage on echocardiography, patients were classified as Stage 0 (no cardiac damage), Stage 1 (left ventricular damage), Stage 2 (mitral valve or left atrial damage), Stage 3 (tricuspid valve or pulmonary artery vasculature damage) or Stage 4 (right ventricular damage). Exclusion criteria were severe aortic stenosis and previous valve repair or replacement. The primary end-point was all-cause mortality. Results A total of 572 patients, aged 70.1±13.9 years, 294 (51.3%) men were enrolled. One third of patients were in NYHA I. Based on the proposed classification, 82 patients (14.3%) were classified in stage 0, 130 (22.7%) in stage 1, 276 (48.2%) in stage 2, 68 (11.8%) in stage 3 and 17 (3.0%) in stage 4. Median follow-up time was 3.3±1.9 years. There was a progressive increase in mortality rates according to staging: 8.5% in stage 0, 10.8% in stage 1, 24.9% in stage 2, 42.6% in stage 3 and 52.9% in stage 4 (p<0.001). On multivariable analysis, the extent of cardiac damage was independently associated with excess mortality (HR 1.69, 95% CI 1.29 to 2.21) Conclusion Our study demonstrated that this new staging system studied for aortic stenosis also provides increased prognostic value to patients with significant aortic regurgitation. This staging system can be helpful to identify the degree of extra-aortic valvular cardiac damage and to optimize the time of valvular intervention. Further prospective studies are needed to confirm the benefit of the applicability of this model in clinical practice. FUNDunding Acknowledgement Type of funding sources: Public hospital(s).

Valve Implantation

Objectives: We describe the outcome of 168 patients with severe symptomatic aortic stenosis treated with transcatheter aortic valve implantation (TAVI). This cohort includes the first in man transarterial and off-pump transapical patients. Methods: The balloon-expandable aortic prosthesis was implanted via the femoral artery or left ventricular apex in 113 and 58 patients respectively. Data are described as 1–57, 58 –114 femoral and 1–58 apical procedures, respectively. Clinical and echocardiographic follow-up occurred at 1, 6, 12, and 24 months. Unsuccessful cases were censored at 30 days. Results: Mean age was 82.5 years (range 50 –97) with 57% males. Procedural success was 94.2% [88%, 96%, & 98%] with no unsuccessful procedures in the last 46 cases. One patient had a successful transfemoral procedure after a prior failure, and 3 patients had successful transapical procedures following failed transfemoral attempts. Logistic EuroSCORE and STS predicted 30-day surgical mortality was 31% [28.4%, 29.1% & 36%], and 10.4% [8.9%, 9.6% & 12.6%] respectively. Observed 30-day mortality was 10.5% [10.5%, 3.5%, & 17.2%], and 0% in the last 39 trans-femoral cases. Intra-procedural mortality was 1.1% [1.8%, 0% & 1.7%]. Peri-procedural stroke occurred in 4% [3.5%, 7%, & 1.7%]. Median hospital stay was 5 days [4, 5, & 7]. Survival at 1, 6, 12 and 24 months was 88%, 80%, 74% [73.9%, 84%, & 65.6%] and 61%. AVA, MG, LVEF and MR significantly improved post TAVI (Table 1 ), and MR, EF, and NYHA class significantly improved during follow-up. MG did not increase during follow-up, but AVA decreased slightly at 1 year (mean difference: 0.2±0.54cm 2 , p=0.04). Mild paravalvular AR was common but severe AR was not observed post-implant or at follow-up. Conclusion: TAVI provides sustained clinical benefit for up to 2 years in patients with symptomatic severe AS and high operative risk. Procedural outcome continues to improve with experience and device development. Table 1: Echocardiographic follow-up

The Impact

AimsThere is an increasing awareness of gender-related differences in patients with severe aortic stenosis and their outcomes after surgical aortic valve replacement (SAVR) and transcatheter aortic valve implantation (TAVI).MethodsData from the IMPULSE registry were analysed. Patients with severe aortic stenosis (AS) were enrolled between March 2015 and April 2017 and stratified by gender. A subgroup analysis was performed to assess the impact of age.ResultsOverall, 2171 patients were enrolled, and 48.0% were female. Women were characterised by a higher rate of renal impairment (31.7 vs 23.3%; p<0.001), were at higher surgical risk (EuroSCORE II: 4.5 vs 3.6%; p=0.001) and more often in a critical preoperative state (7.0vs 4.2%; p=0.003). Men had an increased rate of previous cardiac surgery (9.4 vs 4.7%; p<0.001) and a reduced left ventricular ejection fraction (4.9 vs 1.3%; p<0.001). Concomitant mitral and tricuspid valve disease was substantially more common among women. Symptoms were highly prevalent in both women and men (83.6 vs 77.3%; p<0.001). AVR was planned in 1379 cases. Women were more frequently scheduled to undergo TAVI (49.3 vs 41.0%; p<0.001) and less frequently for SAVR (20.3 vs 27.5%; p<0.001).ConclusionsThe present data show that female patients with severe AS have a distinct patient profile and are managed in a different way to males. Gender-based differences in the management of patients with severe AS need to be taken into account more systematically to improve outcomes, especially for women.

Abstract Introduction Radiation therapy is one of the cornerstones of treatment for many types of cancer. These patients can later in life develop cardiovascular complications associated with radiation treatment. Late cardiovascular effects of radiation treatment include coronary artery disease (CAD), valvular heart disease, congestive heart failure, pericardial disease and sudden death. The most common sign of radiation-induced valvular heart disease is the calcification of the intervalvular fibrosa between the aortic and mitral valve. Case presentation A 71-year-old male patient with a history of Non-Hodgkin lymphoma treated with radiotherapy and chemotherapy 20 years ago, CAD, arterial hypertension, diabetes type II, dyslipidemia, obesity and currently smoking presented in the emergency room in our medical facility with acute pulmonary edema. The patient had unstable angina pectoris in 2018, the coronary angiography showed two-vessel disease with a non-significant stenosis of the left main coronary artery (LMCA) and 70% stenosis of the left anterior descending artery (LAD), for which he refused the percutaneous coronary intervention. At the same time, a transthoracic echocardiography (TTE) showed severe aortic stenosis and moderately severe mitral stenosis, at that time the patient refused the operation. After the initial treatment for pulmonary edema, TTE and transesophageal echocardiography (TEE) were performed and showed a tricuspid aortic valve with calcification of the cusps and a very severe aortic stenosis (planimetric aortic valve area 0.74 cm², functional aortic valve area 0.55 cm², indexed functional aortic valve area 0.25 cm²/m², mean gradient 61 mmHg, peak gradient 100 mmHg, stroke volume (SV) 69 ml, stroke volume index (SVI) 31 ml/m², flow rate 221 ml/s, aortic annulus 20x26 mm). The left ventricle was severely dilated (end diastolic volume 268 ml) with diffuse hypokinesia and severe systolic dysfunction (ejection fraction 32%). We appreciated a calcification of the mitral-aortic intervalvular fibrosa and the mitral annulus, without mitral stenosis but with moderate mitral regurgitation. The calcification of the intervalvular fibrosa suggested our final diagnosis of radiation-induced valvular heart disease with a severe aortic stenosis in low-flow conditions. The patient was successfully treated with transcatheter aortic valve implantation (TAVI). Conclusion Radiation-induced heart disease is a common reality and is destinated to raise due to the increasing number of cancer survivors. Effects are seen also many years after the radiation treatment. The exact primary mechanism of radiation injury to the heart is still unknown. The treatment of radiation-induced valve disease is the same as the treatment of valve disease in the general population. Abstract P1692 Figure. Radiation-induced valvular heart disease

ObjectiveTo determine whether echocardiography-derived left ventricular filling pressure influences survival in patients with severe aortic stenosis (AS) undergoing aortic valve replacement (AVR).MethodsWe retrospectively reviewed 1383 consecutive patients with severe AS, normal ejection fraction and interpretable filling pressure undergoing AVR. Left ventricular filling pressure was determined according to current guidelines using mitral inflow, mitral annular tissue Doppler, estimated right ventricular systolic pressure and left atrial volume index. Cox proportional hazards regression was used to assess the influence of various parameters on mortality.ResultsAge was 75±10 years and 552 (40%) were female. Left ventricular filling pressure was normal in 325 (23%), indeterminate in 463 (33%) and increased in 595 (43%). Mean follow-up was 7.3±3.7 years, and mortality was 1.2%, 4.2% and 18.9% at 30 days and 1 and 5 years, respectively. Compared with patients with normal filling pressure, patients with increased filling pressure were older (78±9 vs 70±12, p<0.001), more often female (45% vs 35%, p=0.002) and were more likely to have New York Heart Association class III–IV symptoms (35% vs 24%, p=0.004), coronary artery disease (55% vs 42%, p<0.001) and concentric left ventricular hypertrophy (63% vs 37%, p<0.001). After correction for other factors, increased left ventricular filling pressure remained an independent predictor of mortality after successful AVR (adjusted HR 1.45 (95% CI 1.16 to 1.81), p=0.005).ConclusionsPreoperative increased left ventricular filling pressure is common in patients with AS undergoing AVR and has important prognostic implications, regardless of symptom status. Future prospective studies should consider whether patients with increased filling pressure would benefit from earlier operation.
