RESUMEN
Aortic stenosis is one of the most frequent valvular diseases in developed countries, and its impact on public health resources and assistance is increasing. A substantial proportion of elderly people with severe aortic stenosis is not eligible to surgery because of the advanced age, frailty, and multiple co-morbidities. Transcatheter aortic valve implantation (TAVI) enables the treatment of very elderly patients at high or prohibitive surgical risk considered ineligible for surgery and with an acceptable life expectancy. However, a significant percentage of patients die or show no improvement in quality of life (QOL) in the follow-up. In the decision-making process, it is important to determine: (i) whether and how much frailty of the patient influences the risk of procedures; (ii) how the QOL and the individual patient's survival are influenced by aortic valve disease or from other associated conditions; and (iii) whether a geriatric specialist intervention to evaluate and correct frailty or other diseases with their potential or already manifest disabilities can improve the outcome of surgery or TAVI. Consequently, in addition to risk stratification with conventional tools, a number of factors including multi-morbidity, disability, frailty, and cognitive function should be considered, in order to assess the expected benefit of both surgery and TAVI. The pre-operative optimization through a multidisciplinary approach with a Heart Team can counteract the multiple damage (cardiac, neurological, muscular, respiratory, and kidney) that can potentially aggravate the reduced physiological reserves characteristic of frailty. The systematic application in clinical practice of multidimensional assessment instruments of frailty and cognitive function in the screening and the adoption of specific care pathways should facilitate this task.
RESUMEN
BACKGROUND AND AIM OF THE STUDY: Patients with asymptomatic aortic stenosis (AS) may have left ventricular systolic dysfunction (LVSD) defined as an impairment of the circumferential and/or longitudinal (C&L) myocardial fibers, despite a preserved left ventricular ejection fraction (LVEF). An assessment was made as to whether the combined LVSD of C&L fibers has a prognostic impact in asymptomatic AS. METHODS: A total of 200 asymptomatic AS patients was analyzed. Midwall shortening and mitral annular peak systolic velocity were considered as indices of C&L function and classified as low if <16.5% and <8.5 cm/s, respectively. The primary outcome was a composite of major cardiovascular events (MACE), including aortic valve-related and ischemic cardiovascular-related events. RESULTS: During a 25-month follow up period, MACE occurred in 69 patients (35%),while 46 of 72 patients (64%) had C&L LVSD and 23 of 128 patients (18%) had not (p <0.001). Cox analysis identified C&L LVSD as an independent MACE predictor, together with aortic transvalvular peak gradient, E/E' ratio and excessive left ventricular mass. C&L-LVSD also predicted the occurrence of aortic valve-related events and ischemic cardiovascular-related events analyzed separately. A receiver operating characteristic curve analysis showed that the area under the curve (AUC) for C&L LVSD in predicting MACE was 0.77, significantly higher (p = 0.002, z-statistic) than the AUCs of C&L fibers considered individually (0.64 and 0.63, respectively). CONCLUSION: C&L-LVSD provides additional prognostic information into traditional risk factors for patients with asymptomatic AS.

In heart failure (HF), cardiac rehabilitation (CR) may reduce decompensations, hospitalization, and ultimately mortality in long term. Many studies over the past decade have demonstrated that aerobic exercise training is effective and safe in stable patients with HF. Exercise CR resulted in a clinically important improvement in the QOL. Several clinical and psychosocial factors are associated with decreased participation in CR programs of elderly HF patients, such as perception of exercise as tiring or painful, comorbidities, lack of physician encouragement, and opinion that CR will not improve their health status. Besides low functional capacity, and chronic deconditioning may also deter patients from participating in CR programs. Recent data suggest that current smoking, a BMI ≥30 kg/m2, diabetes mellitus, and cognitive dysfunction are associated with failure to enroll in outpatient CR in older age group. Moreover the lack of availability of CR facilities or the absence of financial refunds for enrolment of CHF patients in cardiac rehabilitation programs can play a crucial role. Many of this factors are modifiable through patient education and self care strategy instruction, health providers sensibilization, and implementing economic measures in order to make CR affordable.

In the setting of heart failure (HF) pharmacotherapy demonstrates a quantifiable improvement in exercise tolerance also in HF with preserved ejection fraction (HFpEF). For patients with HFpEF, often older, with higher prevalence of hypertension, diabetes mellitus, atrial fibrillation and other comorbidities, endpoints such as quality of life and functional capacity may be more clinically relevant. However several study show as the use of ACE-I and B-blocker were lesser than expected. Beta-blocker therapy is the keystone of pharmacotherapy of HF patients and exercise training is the essential core of rehabilitation programs, it is important to elucidate the relationship between these therapies. Exercise training improves the clinical status of HF, improving left ventricular ejection fraction and improving quality of life, but it is possible that b-blocker may attenuate exercise training adaptations. Despite this, possible adverse b-blocker effects are just presumed and not confirmed by published randomized clinical trials. Metanalysis suggests that b-blocker compared with placebo enhances improvements in cardiorespiratory performance in exercise training intervention. Despite these evidences, prescription of gold standard therapy and adherence are still suboptimal and should be a priority goal for all CR program.

BACKGROUND: Early detection of left ventricular (LV) systolic dysfunction is pivotal in the management of patients with aortic stenosis (AS). LV circumferential and/or longitudinal shortening may be impaired in these patients despite LV ejection fraction is preserved. We focused on prevalence and factors associated with combined impairment of circumferential and longitudinal shortening (C&L) in asymptomatic AS patients. METHODS: Echocardiographic and clinical data from 200 patients with asymptomatic AS of any degree without history of heart failure and normal LV ejection fraction were analyzed. C&L were evaluated by mid-wall shortening (MS) and tissue Doppler mitral annular peak systolic velocity (S'), and classified low if <16.5% and if <8.5 cm/sec, respectively (10th percentiles of controls). RESULTS: Combined C&L dysfunction was detected in 72 patients (36%). The variables associated with this condition were higher LV mass (OR 1.02 [CI 1.01-1.04], P = 0.03), concentric LV geometry (OR 4.30 [CI 1.79-10.34], P = 0.001), increasing pulmonary artery wedge pressure (by E/e' ratio; OR 1.11 [CI 1.04-1.19], P = 0.001). The relation of MS and peak S' was linear and slightly significant in the whole population (r = 0.23; F statistic=0.001), absent in patients with C&L dysfunction (r = 0.04; F = ns), negative (linear model) in the subgroup of patients without C&L dysfunction (r = -0.22; F = 0.02). CONCLUSIONS: C&L dysfunction is present in more than one-third of patients with asymptomatic AS and is associated with concentric LV geometry and higher degree of diastolic dysfunction. The relation between MS and peak S' largely varies in the subgroups with different C&L function.

A bidirectional relationship between kidney and heart function is present in all stages of cardiac and renal disease, from the asymptomatic phase of left ventricular systolic dysfunction to overt heart failure, as well as from the initial reduction of glomerular filtration rate to end-stage kidney disease, respectively. The simultaneous presence of both diseases has a significant impact on prognosis and requires specific therapeutic strategies. The early recognition of abnormalities of renal and myocardial function may have a relevant influence on management of combination of these conditions.

OBJECTIVE: Aim of this study was to compare the hemodynamic profiles of 2 aortic valve bioprostheses: the Carpentier Edwards Perimount Magna (CEPM) valve and the Trifecta valve. METHODS: 100 patients who underwent AVR for severe symptomatic AS between September 2011 and October 2012 were analyzed by means of standard trans-thoracic Doppler-echocardiography. RESULTS: Mean and peak gradients were significantly lower for the 21 mm Trifecta vs CEPM (11 +/- 4 vs 15 +/- 4 mmHg, and 20 +/- 6 vs 26 +/- 7 mmHg, respectively; all p < 0.05) and the 23 mm Trifecta vs CEPM (8 +/- 2 vs 14 +/- 4 mmHg, and 17 +/- 6 vs 25 +/- 9 mmHg; all p < 0.05). Effective orifice area tended to be slightly higher for the Trifecta valve. CONCLUSION: The new bioprosthetic valve Trifecta has an excellent hemodynamic profile, and lower trans-prosthesic gradients when compared to CEPM valve.

BACKGROUND: Pressure/volume (P/V) loops provide useful information on left ventricular performance and prognosis in patients with heart failure (HF) but do not lend themselves to routine clinical practice. The authors developed a noninvasive method to compute individualized P/V loops to predict adverse clinical outcomes in patients with stable HF, which the authors believe can be used clinically. METHODS: A derivation cohort (n = 443 patients) was used to develop an echocardiography P/V loop model, using brachial arterial pressure and trans-thoracic two-dimensional Doppler echocardiographic data. Each patient's P/V loop was depicted as an irregular pentagon, and a centroid was derived for each loop. The centroid distance (CD) from a reference centroid (derived from 101 healthy control subjects) was computed. This model was prospectively applied to 435 patients who constituted the validation cohort. The study end point was a composite of cardiac death or hospitalization for HF among study patients. RESULTS: In the derivation cohort, CD was threefold greater among patients who experienced adverse events than those who did not. During a follow-up period of 30 months (15-45 months), event rates were 35% (72 of 206 patients) and 12% (29 of 237 patients P < .001), respectively, among patients with CD > 33 mL/mm Hg and those with CD ≤33 mL/mm Hg (prognostic cutoff derived by receiver operating characteristic analysis). Multivariate Cox analysis identified CD as an independent predictor of adverse outcome (hazard ratio, 1.61; 95% CI, 1.03-2.50) independently of left ventricular end-diastolic volume, pulmonary capillary wedge pressure, and left ventricular ejection fraction. These conclusions were confirmed in the validation cohort. CONCLUSIONS: The authors propose a method to create a noninvasive P/V loop and its centroid. These data provide useful pathophysiologic and prognostic information in patients with HF.

BACKGROUND: Adjuvant trastuzumab therapy improves the outcome of patients with early breast cancer (EBC) and overexpression of human epidermal growth factor receptor 2 (HER2). However, it is potentially cardiotoxic. This study aims to evaluate the relationship between the use of angiotensin-converting enzyme inhibitors/receptor blockers (ACEi/ARBs) and/or ß-blockers and development of heart failure (HF) and/or left ventricular dysfunction during 1 year of adjuvant trastuzumab therapy. METHODS: A total of 499 women receiving adjuvant trastuzumab therapy for EBC entered in a multicenter registry and were divided into four subgroups according to treatment with ACEi/ARBs and/or ß-blockers. Occurrence of HF and decrease of left ventricular ejection fraction (LVEF; minimum 10 percentage points) were recorded. RESULTS: HF occurred in 2% of patients who did not take either ACEi/ARBs or ß-blockers, 8% of patients receiving ACEi/ARBs alone, 8% receiving ß-blockers alone (p = .03), and 19% receiving both medications (p < .01). The prevalence of patients with LVEF that decreased by at least 10 percentage points was similar in all groups. Combined ACEi/ARBs and ß-blocker therapy was independently associated with hypertension and a significant reduction of LVEF from baseline to 3-month evaluation. The use of ACEi/ARBs alone or ß-blockers alone was predicted only by hypertension. Combined therapy of ACEi/ARBs plus ß-blockers predicted LVEF recovery from the 3-month to 12-month evaluation. CONCLUSIONS: In clinical practice, the degree of hypertension and decrease in LVEF during the first 3 months of adjuvant trastuzumab therapy for EBC are associated with the use of ACEi/ARBs and ß-blockers. The combined use of these two medications is associated with a recovery of LVEF during months 3-12 of adjuvant trastuzumab therapy.

BACKGROUND: Cardiac allograft vasculopathy (CAV) is a major late complication in cardiac transplant recipients and has a relevant impact on outcome of these patients. AIMS OF THIS STUDY: to compare, in cardiac transplant recipients patients, the diagnostic value of pressure/volume relationship (ESPVR) during dobutamine stress echocardiography (DSE) for coronary artery disease, assessed by Multislice Computed Tomography (MSCT), and by coronary angiography (CA). We also analyzed any possible relationship between ESPVR and the Health Related Quality of Life of the patients (HRQoL), evaluated by SF-36 questionnaire. METHODS: 25 consecutive patients underwent DSE within 24 hours after MSCT coronary angiogram and then they underwent CA. The HRQoL questionnaire was administered to the patients in the settings of DSE. They were followed-up for 6 months. RESULTS: DSE has a sensitivity in detecting CAV of 67%, specificity of 95%, positive predictive value of 67% and negative predictive value of 95%; DSE with ESPVR has a sensitivity of 100%, specificity of 95%, positive predictive value of 75%, negative predictive value of 100%; MSCT has a sensitivity of 100%; specificity of 82%; positive predictive value of 43%; negative predictive value of 100%. Htx recipients with a flat-biphasic ESPVR, although asymptomatic, perceived a worst HRQoL compared with the up-sloping ESPVR population, and this is statistically significant for the general health (p 0.0004), the vitality (p 0.0013) and the mental health (p 0.021) SF-36 subscale. CONCLUSIONS: Evaluation with DSE and ESPVR is accurate in the clinical control of heart transplant recipients reserving invasive evaluation only for patients with abnormal contractility indexes.

BACKGROUND: Cognitive impairment (CI) frequently complicates Heart failure (HF) and is associated with increased mortality and morbidity. Previous studies reported that nurse-lead home-based multidisciplinary program (MP) may not improve the prognosis of this high-risk group. In the present study, we analysed the relative effectiveness of an integrated hospital-based MP in patients with cognitive impairment. METHODS: Consecutive (n = 173) community-living outpatients aged > 70 years (mean 77 +/- 6, 48% women) randomized to a MP (n = 86) or usual care (UC) (n = 87) were enrolled in stable clinical conditions. Cognitive status was assessed by means of Folstein Mini Mental State Examination (MMSE). RESULTS: CI (MMSE < or = 24) was present in 41.6% (42,5% UC vs 40.7% MP p =ns). The variables independently associated to CI were: older age, education level <5 years, anemia and severe renal dysfunction. During a 2-year follow-up, 59 patients died (31.4%) with no significant difference between intervention group. At multivariate analysis, in the entire cohort, CI was independently associated to death (HR 2,07 7[95%CI 1,097-3,931]), HF admissions (2,133[1,346-3,381]), death/HF admissions (1,784[1,132-2,811]) and all-cause admissions (1,473[1,008-2,153]. When considered according to intervention groups, CI was independently associated to all-cause death (3,603 [1,553-8,358], death/HF admissions (2,029[1,200-3,432]) and HF admissions (2,474[1,406-4,353]) but not to all-cause admissions. The assignment of patients with CI to MP was associated to a significant reduction in HF admissions vs UC (0,503[0,253-0,999] (all interaction tests p = ns). CONCLUSIONS: This study suggests that CI is very common and associated to worse prognosis in heart failure and that hospital-based MP seems to improve outcomes in these patients through reduction of heart failure hospital admission.

In the year 2006 the Italian Association of Hospital Cardiologists (ANMCO) promoted a Consensus Conference among professional Scientific Societies in order to redefine the role and core responsibilities of each health professionals involved in heart failure management in a novel integrated network. Five years later, a questionnaire has been proposed to each Italian Regional President of the Association, in order to assess the implementation of the proposed management strategies in the different clinical scenarios of the Italian Regions. Although the Document utilization is not homogeneous through Italy, it is still considered a valuable tool of work.

BACKGROUND: Mineralocorticoid receptor antagonists (MRAs) are a class of drugs still underused in heart failure with reduced ejection fraction. Hyperkalemia, worsening of renal function and gynecomastia are the main causes of the MRA missed prescription but also an inadequate knowledge of this class of drugs may represent a reason for their underuse. The aim of this project was to evaluate the possible usefulness of a unique and innovative web-based platform in order to identify the main issues related to the underuse of MRAs and to discuss shared strategies of interventions to overcome the obstacles to MRA prescription. METHODS: The "HF Clinical Practice project" enrolled 55 hospital cardiologists. It was based on the development and production of the eCaseTrack platform which was capable of activating a content-sharing system between professionals and specialists, using a mixed-methods study consisting of a survey, shared clinical experiences, training and consensus mini-Delphi method. RESULTS: The results of the survey showed that the respondents substantially agreed about the criteria for MRA prescription (NYHA class, left ventricular ejection fraction, glomerular filtration rate and serum potassium). This agreement was confirmed by mini-Delphi, by which the use of MRAs in patients with hypotension, hyperkalemia and gynecomastia emerged as the most controversial issue. CONCLUSIONS: A web-based system of sharing clinical experiences and discussing controversial issues, is useful to implement the introduction of a proven efficacious therapeutic strategy which is still underused in current clinical practice.

INTRODUCTION AND OBJECTIVES: Octogenarians represent the most rapidly expanding population segment in Europe. The prevalence of heart failure (HF) in this group exceeds 10%. We assessed changes in clinical characteristics, therapy, and 1-year outcomes over 2 decades in chronic HF outpatients aged ≥ 80 years enrolled in a nationwide cardiology registry. METHODS: We included 2520 octogenarians with baseline echocardiographic ejection fraction measurements and available 1-year follow-up, who were recruited at 138 HF outpatient clinics (21% of national hospitals with cardiology units), across 3 enrolment periods (1999-2005, 2006-2011, 2012-2018). RESULTS: At recruitment, over the 3 study periods, there was an increase in age, body mass index, ejection fraction, the prevalence of obesity, diabetes, dyslipidemia, pre-existing hypertension, and atrial fibrillation history. The proportion of patients with preserved ejection fraction rose from 19.4% to 32.7% (P for trend <.0001). Markers of advanced disease became less prevalent. Prescription of beta-blockers and mineralocorticoid receptor antagonists increased over time. During the 1-year follow-up, 308 patients died (12.2%) and 360 (14.3%) were admitted for cardiovascular causes; overall, 591 (23.5%) met the combined primary endpoint of all-cause mortality or cardiovascular hospitalization. On adjusted multivariable analysis, enrolment in 2006 to 2011 (HR, 0.70; 95%CI, 0.55-0.90; P=.004) and 2012 to 2018 (HR, 0.61; 95%CI, 0.47-0.79; P=.0002) carried a lower risk of the primary outcome than recruitment in 1999 to 2005. CONCLUSIONS: Among octogenarians, over 2 decades, risk factor prevalence increased, management strategies improved, and survival remained stable, but the proportion hospitalized for cardiovascular causes declined. Despite increasing clinical complexity, in cardiology settings the burden of hospitalizations in the oldest old with chronic HF is declining.
RESUMEN
AIMS: To assess adherence to guideline recommendations among a large network of Italian cardiology sites in the management of acute and chronic heart failure (HF) and to evaluate if an ad-hoc educational intervention can improve their performance on several pharmacological and non-pharmacological indicators. METHODS AND RESULTS: BLITZ-HF was a cross-sectional study based on a web-based recording system with pop-up reminders on guideline recommendations used during two 3-month enrolment periods carried out 3 months apart (Phase 1 and 3), interspersed by face-to-face macro-regional benchmark analyses and educational meetings (Phase 2). Overall, 7218 patients with acute and chronic HF were enrolled at 106 cardiology sites. During the enrolment phases, 3920 and 3298 patients were included, respectively, 84% with chronic HF and 16% with acute HF in Phase 1, and 74% with chronic HF and 26% with acute HF in Phase 3. At baseline, adherence to guideline recommendations was already overall high for most indicators. Among acute HF patients, an improvement was obtained in three out of eight indicators, with a significant rise in echocardiographic evaluation. Among chronic HF patients with HF and preserved or mid-range ejection fraction, performance increased in two out of three indicators: creatinine and echocardiographic evaluations. An overall performance improvement was observed in six out of nine indicators in ambulatory HF with reduced ejection fraction patients with a significant increase in angiotensin receptor-neprilysin inhibitor prescription rates. CONCLUSIONS: Within a context of an already elevated level of adherence to HF guideline recommendations, a structured multifaceted educational intervention could be useful to improve performance on specific indicators. Extending this approach to other non-cardiology healthcare professionals, who usually manage patients with HF, should be considered.

AIMS: Ageing and comorbidities are increasing frailty/complexity of heart failure (HF) patients globally. We assessed evolving trends over two decades according to patients' age and time of recruitment in a nationwide cardiology setting in Italy. METHODS AND RESULTS: Chronic HF outpatients recruited between 1999 and 2018 (N = 14,823) were divided into 3 cohorts: 1999-2005 (N = 5404); 2006-2011 (N = 3971); 2012-2018 (N = 5448). We analyzed temporal changes in clinical characteristics, therapies, and outcome (1-year all-cause mortality/cardiovascular hospitalization), overall and by age group: <65 (n = 5465); 65-79 (n = 6838); ≥80 (n = 2520) years old. Across enrolment epochs, comorbidities (atrial fibrillation, hypertension, obesity) increased by both epoch/age groups (p < 0.001), whereas the prevalence of ischemic etiology declined among patients ≥65 years (p = 0.05). Accordingly, the preserved LVEF phenotype (HFpEF) increased in all age categories (p < 0.001) over time. Moreover, the use of betablockers, mineralocorticoid-receptor antagonists and loop-diuretics rose by enrolment epoch in all age groups (p < 0.05). In parallel with these epidemiologic/treatment changes, age-adjusted survival free from cardiovascular hospitalization improved over time (p < 0.0001). However, divergent trends in the end-point components were apparent according to age groups: mortality decreased in patients<80 years, although hospitalizations remained stable in the youngest group, while subjects ≥65 years were less likely to be admitted for cardiovascular causes (all p < 0.005). CONCLUSIONS: Over two decades in a cardiology outpatient setting, the prevalence of comorbid HFpEF increased in all age categories. Mortality improved among patients<80 years and cardiovascular hospitalizations decreased in patients≥65 years. These findings point to the value of cardiologist' input in the management of adult chronic HF patients at all ages.

OBJECTIVES: This study was designed to describe Doppler-echocardiography values of Carpentier-Edwards Perimount Standard (CEPS) and Carpentier-Edwards Perimount Magna (CEPM) aortic prosthetic valves, evaluated by a single, experienced echo-laboratory, early in the postoperative phase. METHODS: Three-hundred-seventy-seven consecutive patients, who had had a CEPS or a CEPM implanted in our Hospital due to aortic stenosis and/or insufficiency, underwent baseline Doppler echocardiography evaluation within 7 days after surgery. Hemodynamic performances of CEPS and CEPM were accurately described, evaluating flow-dependent (transprosthetic velocities and gradients) and flow-independent (effective orifice area, indexed effective orifice area and Doppler velocity index) Doppler-echocardiography parameters. RESULTS: Out of the 377 patients 48.8% were men (n = 184), mean age was 74.63 ± 6.77 years, mean BSA was 1.78 ± 0.18 m2, mean ejection fraction was 57.78 ± 8%. Two-hundred and sixty two CEPS and 115 CEPM were implanted. Comparing size-by-size CEPS with CEPM, both prostheses showed a good hemodynamic profile, with fairly similar values of pressure gradients (PGmax and mean, in mmHg, = 37,18 ± 11.57 and 20.81 ± 7.44 in CEPS n°19 compared to 32,47 ± 7,76 and 17,67 ± 4.63 in CEPM n°19 and progressively lower in higher sized prostheses, having PGmax and mean 15 ± 3,16 and 9.15 ± 1,29 in CEPS n°29 compared to 15,67 ± 1,53 and 9 ± 1 in CEPM n°29) and EOAi (being 0,65 ± 0,33 cm²/m² in CEPS n°19 compared to 0,77 ± 0,29 cm²/m² in CEPM n°19 and progressively higher in higher sized prostheses, being 1,28 ± 0,59 cm²/m² in CEPS n°29 compared to 1,07 ± 0,18 cm²/m² in CEPM n°29), the latter resulting, however, basically less flow obstructive. CONCLUSIONS: Our data confirm the good hemodynamic performance of both aortic bioprostheses and the more favourable hemodynamic profile of CEPM compared to CEPS, pointing out the need to perform routinely an accurate baseline Doppler-echocardiography evaluation early after surgery to allow an adequate interpretation of data at follow-up.

INTRODUCTION: The anterior mitral leaflet cleft is an unusual congenital lesion most often encountered in association with other congenital heart defects. The isolated anterior leaflet cleft is quite a rare anomaly and is usually cause of mitral valve regurgitation. The importance of the lesion is that it is often correctable. When feasible, cleft suture and, eventually, annuloplasty are preferable to valve replacement. Echocardiography is the first choice technique in the evaluation of mitral valve disease, providing useful information about valve anatomy and hemodynamic parameters. CASE PRESENTATION: We present a case of an isolated anterior mitral leaflet cleft producing moderate-severe mitral regurgitation correctly identified by echocardiography and successfully surgically corrected. CONCLUSION: Isolated cleft is a rare aberration, that has to be known in order to be diagnosed. Transthoracic and transesophageal echocardiography is the most useful non invasive technique for cleft diagnosis and to indicate the right surgical correction.

BACKGROUND: This study was conducted to assess the accuracy of harmonic imaging 2D-transthoracic echocardiography (2D-TTE) segmental analysis compared to surgical findings, in degenerative mitral regurgitation (MR). METHODS: Seventy-seven consecutive patients with severe degenerative MR were prospectively enrolled. Preoperative 2D-TTE with precise localization of prolapsing or flailing scallops/segments was performed. All patients underwent mitral valve surgical repair. Surgical reports (SR), including valve description, were used as references for comparisons. A postoperative control 2D-TTE was performed. RESULTS: Out of 462 scallops/segments studied, surgical inspection identified 102 prolapses or flails (22%), 92 of which had previously been detected by 2D-TTE (90.2% sensitivity, 100% specificity). Agreement between preoperative 2D-TTE segmental analysis and SR was 97.8% (k = 0.93; p < 0.0001). Sixty-nine out of 77 2D-TTE reports were completely concordant with SR (89.6% diagnostic accuracy). None of the 8 non-concordant 2D-TTE reports were in complete disagreement with SR. P2 scallop was always involved in posterior leaflet prolapse or flail and was described correctly by 2D-TTE in 68 out of 69 patients (98,7% agreement, k = 0,93; 98.5% sensitivity). The anterior leaflet was involved in 14 patients (18%); A2 segment was involved in all of those cases and was correctly detected by 2D-TTE in 13 (98,7% agreement, k = 0,95; 92,8% sensitivity). Antero-lateral and postero-medial para-commissural prolapse or flail had a lower prevalence (14% and 10% respectively), with 2D-TTE sensitivity respectively of 64% and 50%. CONCLUSIONS: 2D-TTE, performed by an experienced echo-lab, has very good diagnostic accuracy in localizing the scallops/segments involved in degenerative MR, particularly for the middle ones (P2-A2), which represent almost the totality of prolapses. More invasive, time consuming and expensive exams should be reserved to selected cases.
