The study aim was to evaluate whether, in patients with severe mitral regurgitation (MR), tricuspid valve remodeling was independent of the degree of functional tricuspid regurgitation (FTR) present. Whether any differences in the analysis remodeling, as assessed by two-dimensional (2D) and three-dimensional (3D) echocardiography, can be demonstrated was also addressed.A total of 188 patients (mean age 63.5 +/- 16.0 years) with severe organic or functional MR with or without associated FTR, and 30 normal controls (mean age 59.2 +/- 15 years) were enrolled in the study. Subsequently, both 2D and 3D transthoracic anatomic and functional parameters of the tricuspid valve were analyzed.Patients and controls differed in all 2D and 3D parameters of tricuspid valve remodeling, except for the 2D end-diastolic annular diameter and circularity indices. The patients were then allocated to either group A (trivial/mild FTR) or group B (moderate/severe FTR). Significant differences were identified between groups A and B compared to controls in all tricuspid valve remodeling indices, except for the diastolic 2D annular diameter and circularity indices. Groups A and B had similar 2D and 3D parameters of tricuspid valve remodeling. The right ventricular end-diastolic diameter (RVEDD) (beta = 0.24, 95% CI: 0.11 to 0.22, p = 0.02) and fractional area change (beta = -0.48, 95% CI: -0.24 to 0.09, p = 0.0001, R2 = 0.22) were independent predictors of the tenting area, whereas the RVEDD was the only independent predictor of the diastolic 3D tricuspid annular area (beta = 0.53, 95% CI: 1.2 to 2.7, p = 0.0001, R2 = 0.28).In patients with severe MR, tricuspid valve remodeling was also demonstrated in those with trivial/mild FTR, but was better characterized by 3D echocardiography. Tricuspid valve remodeling and right ventricular dilation were the main determinants of tricuspid valve regurgitation.

The introduction of three-dimensional echocardiography and its evolution from time-consuming and cumbersome off-line reconstruction to real-time volumetric technique (real-time three-dimensional echocardiography) are one of the most significant advances in ultrasound imaging of the heart of the past decade. This imaging modality currently provides realistic views of cardiac valves capable of demonstrating the anatomy of various heart valve diseases in a unique, noninvasive manner. In addition, real-time three-dimensional echocardiography offers completely new views of the valves and surrounding structures, and allows accurate quantification of severity of valve disease. This article reviews the advantages of real-time three-dimensional echocardiography in assessing heart valves and shows also technological limitations in order to provide the scientific basis for its clinical use.

La gravidanza accentua patologie cardiache. Lo scopo di questo lavoro clinico è presentare le differenti gestioni anestesiologiche per taglio cesareo emergente in 2 pazienti con insufficienza cardiaca. La fisiopatologia dell’insufficienza cardiaca è descritta secondo la causa primaria della malattia e secondo e l’impatto di 2 differenti tecniche anestetiche. Vengono presentati 2 casi verificatisi in un ospedale universitario. Entrambe le pazienti hanno lasciato l’ospedale in buone condizioni generali. Caso 1: paziente incinta con insufficienza aortica grave che ha ricevuto anestesia epidurale. Caso2: paziente incinta con cardiomiopatia peripartum che ha ricevuto anestesia generale. Le terapie mediche e chirurgiche per l’insufficienza aortica e per la cardiomiopatia peripartum sono in evoluzione. Per la gestione appropriata di questi casi si richiede un’adeguata conoscienza del campo anestesiologico. Noi abbiamo modulato le tecniche anestesiologiche sulle caratteristiche specifiche delle nostre 2 pazienti. Gli effetti positivi della simpatectomia sono stati osservati nel periodo post-operatorio per il caso 1; per il caso 2 l’uso di alti dosi di oppiacei ha minimizzato il pericolo di variazioni cardiovascolari, ma in questo caso deve essere possibile un’immediata rianimazione del bambino. Il problema più difficile per l’anestesista è la scelta della tecnica anestesiologica in ostetricia: una scelta ottimale richiede una conoscenza approfondita della fisiopatologia cardiaca. Pregnancy exacerbates heart diseases. The aim of this clinical report is to review the different anesthesiological management of emergent cesarean section in 2 patients with heart failure. The pathophysiology of heart failure is described according to the primary cause of disease, as well as the impact of 2 different anesthetic techniques. Two case reports of a university referral hospital are presented. Both patients left the hospital in good general conditions. Case 1: a pregnant patient with severe aortic regurgitation who received epidural anesthesia. Case 2: a pregnant patient with peripartum cardiomyopathy who was given general anesthesia. Medical and surgical therapies for aortic regurgitation and peripartum dilated cardiomyopathy are evolving. Adequate knowledge of anesthesiology is required to appropriately manage these cases. We tailored the anesthetic technique to the specific characteristics of our 2 patients. The beneficial effects of sympathectomy were observed in the postoperative period of case 1; the use of high doses opiates minimised dangerous cardiovascular changes in case 2, but rapid resuscitation of the baby should be available. Selection of the anesthetic technique in obstetrics is the most challenging issue for the anesthesiologist: extensive knowledge of the pathophysiology of heart disease is required for an optimal choice.

We assessed whether the presence of latent myocardial dysfunction, evaluated by echocardiographic derived force-frequency relationship (FFR) during exercise, predicts the appearance of stress-induced pulmonary hypertension in minimally symptomatic patients with severe mitral regurgitation (MR). Two groups of patients were identified: group I with normal (less than or equal to40 mm Hg) and group II with abnormal (>40 mm Hg) peak stress systemic pulmonary artery pressure. Group I had normal and upsloping FFR and group II had abnormal flat or biphasic FFR. Therefore, in patients with severe MR and apparently normal left ventricular function, the stress-induced pulmonary hypertension seems to be related to the presence of latent left ventricular dysfunction.

Prophylactic valve replacement in asymptomatic patients with severe aortic stenosis is controversial. Most authors consider that patients could be managed without surgery until symptoms develop. The incidence of sudden death in patients without symptoms is low, < 1%/year and valve replacement is complicated by an operative mortality up to 5 and 1-2% of incidence of valve-related major events. Early surgical approach is suggested by several observations. The first one is the unpredictable risk of myocardial fibrosis after long standing left ventricular hypertrophy and pressure overload, with associated systolic and diastolic dysfunction. Left ventricular impairment can persist after valve replacement influencing exercise capacity and survival in selected patients. On the other hand, major improvement in myocardial protection techniques, intraoperative monitoring with transesophageal echocardiography, prosthetic design (stentless, supra-annular), all have reduced in-hospital mortality and morbidity. More precise recommendations can be made according to an improved characterization of the patients from fast to slow evolution, according to age, type of aortic stenosis, degree of calcification, changes in transaortic gradients over time, tolerance to exercise test and response of aortic valve area to dobutamine. In patients with high risk of progression (severely calcified valve, Doppler velocity > 4 m/s, rapidly increasing with time), indirect evidence of myocardial fibrosis (excessive left ventricular hypertrophy, systolic or diastolic dysfunction), and need of myocardial revascularization, an early surgical approach should be considered.

Background . The minor technical and time requirements with respect to the maze operation combined with a comparable efficacy has led to an increasing popularity of left atrial approaches to treat atrial fibrillation. We report our experience with a left atrial procedure based on extensive use of epicardial radiofrequency ablation in an effort to minimize cardiac arrest time. Methods . A total of 132 consecutive patients with atrial fibrillation (121 chronic, 11 paroxysmal) undergoing open heart surgery had combined intraoperative ablation. An original set of left atrial lesions was performed using a radiofrequency linear catheter. Most of the ablations were performed epicardially before aortic cross-clamping. Patients with contraindications to the epicardial approach had the whole lesion set performed endocardially. Results . The mean cardiac arrest time spent for open heart ablations was significantly shorter (5.2 ± 0.9 minutes with modern catheters) when the epicardial approach was used (107 of 132 patients, 81%). Hospital mortality was 0.8%. Freedom from atrial fibrillation was 77% 3 years after the operation. Of all the variables analyzed, only age at surgery and early postoperative arrhythmias increased the risk of recurrent atrial fibrillation. Overall 3-year survival was 94%. The 3-year actuarial freedom from stroke was 98%. No patient required implantation of a permanent pacemaker. Atrial contractility was recovered in all patients with stable sinus rhythm. Conclusions . Left atrial radiofrequency ablation allows recovery of sinus rhythm and atrial function in the great majority of patients with atrial fibrillation who undergo open heart surgery. The epicardial radiofrequency approach is a safe and effective means to cure atrial fibrillation with negligible technical and time requirements.

Many different doses and administration schemes have been proposed for the use of the antifibrinolytic drug tranexamic acid during cardiac surgery. This study evaluated the effects of the treatment using tranexamic acid during the intraoperative period only and compared the results with the effects of the treatment continued into the postoperative period.Patients undergoing elective cardiac surgery with use of cardiopulmonary bypass (N = 510) were treated intraoperatively with tranexamic acid and then were randomized in a double-blind fashion to one of three postoperative treatment groups: group A: 169 patients, infusion of saline for 12 h; group B: 171 patients, infusion of tranexamic acid, 1 mg x kg(-1) x h(-1) for 12 h; group C: 170 patients, infusion of tranexamic acid, 2 mg x kg(-1) x h(-1) for 12 h. Bleeding was considered to be a primary outcome variable. Hematologic data, allogeneic transfusions, thrombotic complications, intubation time, and intensive care unit and hospital stay duration also were evaluated.No differences were found among groups regarding postoperative bleeding and outcomes; however, the group treated with 1 mg x kg(-1) x h(-1) tranexamic acid required more units of packed red blood cells because of a significantly lower basal value of hematocrit, as shown by multivariate analysis.Prolongation of treatment with tranexamic acid after cardiac surgery is not advantageous with respect to intraoperative administration alone in reducing bleeding and number of allogeneic transfusions. Although the prevalence of postoperative complications was similar among groups, there is an increased risk of procoagulant response because of antifibrinolytic treatment. Therefore, the use of tranexamic acid during the postoperative period should be limited to patients with excessive bleeding as a result of primary fibrinolysis.

OBJECTIVE:Repair of mitral regurgitation (MR) is more demanding in case of prolapse of the anterior leaflet, posterior leaflet with calcified annulus, or prolapse of both leaflets. We evaluated a repair which consists of anchoring the free edge of the prolapsing leaflet to the corresponding free edge of the facing leaflet: the 'edge-to-edge' (E-to-E) technique. The correction results in a double orifice valve when the prolapse is in the middle portion of the leaflet and in a smaller valve orifice when the prolapse is close to a commissure.METHODS:Out of 432 patients with MR submitted to valve repair between January 1991 and September 1997, 121 (mean age 56 +/- 15.8 years) underwent E-to-E correction. The most prevalent etiology was degenerative disease (82 patients, 68%). The mechanism of MR was anterior leaflet prolapse (61 patients), posterior leaflet prolapse (24 patients), prolapse of both leaflets (28 patients) and other complex mechanisms (8 patients). In 72 patients, a double orifice was created, the paracommissural repair was done in 49 patients.RESULTS:Hospital mortality was 1.6%. Overall survival was 92 +/- 3.1% at 6 years with 95 +/- 4.8% freedom from reoperation. Mortality was unrelated to the type of repair. Mitral stenosis was never observed after the correction. At the follow-up (mean 2.2 +/- 1.5 years), all patients but 15 are class I or II. Symptoms at the follow-up are not related to residual MR.CONCLUSIONS:Midterm results of this alternative repair technique are promising, considering the high prevalence of complex anatomical lesions. The technique is simple, easily reproducible and rapidly feasible also when mitral exposure is suboptimal.

Background and aim of the study: The edge-to-edge technique is used to restore valvular competence in mitral insufficiency. The efficacy of the method is under debate due to the potential for creating functional mitral stenosis. An exercise echocardiographic study was carried out to investigate valve function and hemodynamics in patients who had undergone double-orifice mitral valve repair. Methods: Thirty patients (mean age 49.1 +/- 12.7 years) with previous double-orifice mitral valve repair underwent exercise echocardiography (10 W/min). An annular prosthesis was present in 28 patients (93%). The mean and maximum mitral valve gradient, planimetric valve area, stroke volume, systolic pulmonary artery pressure, heart rate and systolic blood pressure were measured at baseline and at peak stress. Results: At peak stress, heart rate (77.7 +/- 12.2 versus 118.6 +/- 26.0 beats/min, p < 0.00001), systolic blood pressure (124.1 +/- 10.9 versus 146.6 +/- 22.8 mmHg, p < 0.00001) and stroke volume (78.0 +/- 10.2 versus 97.0 +/- 15.1 ml, p

Objective: To assess regional mechanical dyssynchrony as a determinant of the degree of functional mitral regurgitation (FMR). Setting: Tertiary cardiology clinic. Patients: 74 consecutive patients with left ventricular (LV) dysfunction (ejection fraction Methods: Effective regurgitant orifice (ERO) area, indices of mitral deformation (systolic valvular tenting, mitral annular contraction) and of global LV function and remodelling (ejection fraction, end systolic volume, sphericity index) and local remodelling (papillary-fibrosa distance, regional wall motion score index), and tissue Doppler-derived dyssynchrony index (DI) (regional DI, defined as the standard deviation of time to peak myocardial systolic contraction of eight LV segments supporting the papillary muscles attachment) were measured. Results: All the assessed variables correlated significantly with ERO. By multivariate analysis, systolic valvular tenting was the strongest independent predictor of ERO (R 2 = 0.77, p = 0.0001), with a minor influence of papillary-fibrosa distance (R 2 = 0.77, p = 0.01) and regional DI (R 2 = 0.77, p = 0.03). Local LV remodelling (regional wall motion score index: R 2 = 0.58, p = 0.001; papillary-fibrosa distance: R 2 = 0.58, p = 0.002) and global remodelling indices (sphericity index: R 2 = 0.58, p = 0.003) were the main determinants of systolic valvular tenting, whereas regional DI did not enter into the model. Regional DI was an independent predictor of ERO (R 2 = 0.56, p = 0.005) in patients with non-ischaemic LV dysfunction but not in patients with ischaemic LV dysfunction when these groups were analysed separately. Conclusions: The degree of FMR is associated mainly with mitral deformation indices. The regional dyssynchrony also has an independent association with ERO but with a minor influence; however, it is not a determinant of FMR in patients with ischaemic LV dysfunction.

Refractory angina pectoris (RAP) represents a clinical condition characterized by frequent episodes of chest pain despite therapy optimization. According to myocardial stunning and myocardial hibernation definitions, RAP should represent the ideal condition for systolic dysfunction development. We aim to investigate the evolution of left ventricular (LV) function in patients with RAP. A retrospective study which encompasses 144 patients with RAP referred to our institution from 1999 to December 2014 was performed. Of them, 88 met the inclusion criteria, and LV function was assessed by echocardiography. All of them had persistent angina episodes on top of optimal medical therapy and evidence of significant inducible myocardial ischemia and no further revascularization options. Nitrates consumption rate, time of angina duration, and the number of angina attacks were evaluated. In the whole population, ejection fraction (EF) was 44% ± 2. EF was significantly lower in patients with previous myocardial infarction (41% ± 1.5 vs 51% ± 1.8, p 5 years (5 years 44% ± 2 [n = 44]; p 0.02). Long-term LV function in patients with RAP is generally preserved. A previous history of myocardial infarction is the only determinant in the development of systolic dysfunction. In conclusion, frequent angina attacks and a long-term history of angina are not apparently associated to worse LV function.

Objective: To evaluate the feasibility of mitral valve (MV) reconstruction protocol by real-time 3D echocardiography (RT3DE) in the assessment mitral regurgitant (MR) lesions, and to determine the accuracy of RT3DE compared with transthoracic (TTE) and transesophageal (TEE) echocardiographies using surgical findings as gold standard. Patients and methods: Sixty-three consecutive patients (mean age 61.7 +/- 12.5 years, 35 men and 28 women) with severe organic MR were enrolled. Data were acquired in zoom and in full-volume modes from apical and/or parasternal windows. A volume rendered en-face view of MV and five serial longitudinal cut planes were reconstructed to visualize all segments of both leaflets. Results: The feasibility of RT3D reconstruction was 94%. Compared with surgical diagnosis, the accuracy of RT3D was 91% for aetiology, 92% for mechanisms, 94% for prolapse, 88% for flail and 94% for defect location. Diagnostic accuracy was significant higher for RT3D than TTE for all end points except for flail lesion and similar to TEE but inferior to this for flail lesion. The accuracy, sensitivity and specificity were higher in patients with good-excellent than those with poor image quality regarding aetiology, mechanisms and defect location (all p=0.0001). Conclusions: RT3D imaging of MV is feasible and accurate in defining aetiology, mechanism and defect location in patients with MR and has incremental diagnostic value if TTE is inconclusive and similar diagnostic value of TEE except for flail lesion. RT3D, at least in patients with good acoustic window, may obviate the need for subsequent TEE and/or can be considered a complementary technique to study MV in patients with MR.

BACKGROUND This observational study was designed to evaluate the prevalence of coronary microvascular dysfunction (CMD) in asymptomatic patients affected by systemic sclerosis (SSc), stratifying the results according to the limited (lcSSc) and the diffuse (dcSSc) forms of the disease. METHODS AND RESULTS We enrolled 19 consecutive asymptomatic patients with dcSSc (n=7) or lcSSc (n=12). In all subjects, coronary flow reserve (CFR) was assessed by measuring diastolic coronary flow velocities in the left anterior descending artery by pulsed wave Doppler at baseline and after dipyridamole infusion (0.84 mg·kg(-1)·6 min(-1)). Wall motion score index was evaluated at baseline and during stress. We enrolled 20 healthy subjects as controls. Mean CFR was 1.96±0.62 in patients and 2.69±0.47 in controls (P

Background Doppler of mitral and pulmonary vein flows are used to estimate left ventricular (LV) filling pressure. Mitral regurgitation (MR) makes unreliable these parameters by inducing changes of both mitral inflow and pulmonary vein flow. Objectives To evaluate whether Doppler tissue imaging (DTI) diastolic indices obtained at the level of LV lateral mitral annulus can provide accurate estimation of LV filling pressure in patients with MR. Methods Forty-three patients (age 55 +/- 11 years) with severe MR and mean LV ejection fraction (EF) 58 +/- 13 were enrolled, 10 (23%) with LV EF 50%. Doppler signals from the mitral inflow, pulmonary venous flow, and DTI indices of the lateral mitral annulus were obtained. LV end-diastolic pressure (LVEDP) was measured invasively with fluid-filled catheter. Results In the overall population, the majority of standard Doppler and DTI indices correlated with LVEDP, but the multivariate analysis showed that the ratio of mitral velocity to early diastolic velocity of the mitral annulus (E/Em ratio) (beta = .87, P = .0001) was independent predictor of LVEDP (R-2 = 0.74, SE = 4, P = .0001). An E/Em ratio >10 predicted an LVEDP >15 mm Hg (sensitivity 90%, specificity 83%). In both groups with LV EF >50% (beta = .77, P = .005; cumulative R-2 = 0.73, SE = 2.5, P = .0001) and 50% and

Although the mechanism of ischemic mitral regurgitation (MR) is understood, the echocardiographic picture of ischemic MR is not homogeneous. Ninety-two consecutive patients with chronic ischemic MR due to restricted motion were divided into two groups according to tethering pattern: the asymmetric group with predominant posterior tethering of both leaflets (54 patients) and the symmetric one with predominant apical tethering of both leaflets (38 patients). The mitral deformation indexes, LV global (volume, function and sphericity) and local (papillary muscle displacements and regional wall motion score index) remodeling were evaluated. All indexes of global LV remodeling were significantly higher in the symmetric than asymmetric group (all p

Transesophageal echocardiography has been widely used as a diagnostic tool during the past two decades to detect cardiac abnormalities that are not visible or poorly visible with transthoracic echocardiography. At present, transesophageal echocardiography is a cornerstone of modern diagnosis of several cardiac diseases, providing diagnostic, prognostic and therapeutic information. In this review, the present status of transesophageal echocardiography not only as a diagnostic tool, underlining its effects on clinical decision making, but also as a monitoring adjunct for many interventional cardiac procedures is examined.

The aim of this study is to evaluate the role of contrast transesophageal echocardiography (cTEE) in the diagnostic characterization of acute aortic syndromes (AAS) [aortic dissection, intramural hematoma, penetrating ulcer]. We enrolled 66 non-consecutive patients with clinical suspicion of AAS. Standard transesophageal echocardiography and cTEE were performed prior to gated-CT angiography, which has been assumed as refer- ence standard. cTEE was obtained with a single bolus of contrast agent injection. The definitive diagnosis of AAS was made in 48 patients by gated-CT angiography: 22 aortic dissections, 15 intramural hematomas and 11 pene- trating aortic ulcers. Standard TEE and cTEE correctly diagnosed AAS in 87 and 100 % (P = 0.03) cases respectively. Standard TEE correctly diagnosed aortic dissection in 20/22 (91 %) and cTEE in 22/22 (100 %) (P = 0.5) cases. cTEE was superior than standard TEE in the visualization of false lumen entry tear (22/22 vs. 16/22, P = 0.03). Standard TEE correctly diagnosed intramural hematoma in 11/15 and cTEE 15/15 (P = 0.12) cases. Microtears were identified in 3 patients by cTEE an in 1 patient by standard TEE (P = 0.4). The presence of focal contrast enhancement was identified in 4 and 0 patients by cTEE and standard TEE respectively (P = 0.06). Both standard and cTEE correctly diagnosed penetrating aortic ulcer in 11/11 (100 %) (P = 1.0) cases. cTEE provides additional value over standard TEE in the diagnosis and in the anatomic and functional characterization of AAS.

We evaluate, in 37 consecutive patients (mean age 67 +/- 9 years) with functional mitral regurgitation (FMR), several rest and stress echocardiographic predictors of outcome. Rest end-systolic volume, peak stress end-diastolic volume and effective regurgitant orifice were independent predictors of death at 25 months follow-up. Therefore, rest and stress echocardiographic evaluation of patients with FMR provides strong prognostic information. (c) 2007 Elsevier Ireland Ltd. All rights reserved.

Aims The prognostic role of tricuspid regurgitation (TR) associated with organic left-sided valvular heart disease is well known. However, no data are available regarding the prognostic value of functional TR (FTR) in patients with functional mitral regurgitation (FMR) and left ventricular (LV) dysfunction. The purpose of this study was to evaluate the prognostic role of FTR for occurrence of heart failure (HF) and mortality in patients with FMR. Methods and results We enrolled 373 consecutive patients (mean age 68 ±11 years) with LV dysfunction and at least mild FMR and with or without FTR, both quantitated by echocardiography. The median follow-up was 32 months (range 1–120 months); 132 (35.4%) and 97 patients developed HF or died, respectively. The incidence of HF at 3 and 6 years was 36 ±2% and 55 ±4%, respectively. Moderate to severe FTR [hazard ratio (HR) 1.4, 95% confidence interval (CI) 1.1–2.1, P = 0.01) was an independent determinant of HF. The incidence of HF was 41 ±5, 46 ±7, 57 ±7, and 65 ±8% for patients without, and with mild, moderate, and severe FTR respectively (P = 0.03). At 3 and 6 years the survival free of all-cause mortality was 77.5 ±2% and 60 ±3%, respectively. Moderate to severe FTR (HR 1.6, 95% CI 1.2–2.1, P = 0.01) was an independent determinant of overall mortality. At 6 years, survival free of all-cause mortality was 69 ±2.5, 67 ±2.1, 51 ±2.5, and 40 ±4.8% for patients without, and with mild, moderate, and severe FTR, respectively (P = 0.004). Conclusions Moderate or more FTR is independently associated with worse survival and a high incidence of HF episodes in patients with FMR.

Aims To assess long-term prognosis in patients with functional mitral regurgitation (FMR) and left ventricular (LV) dysfunction, receiving current standard pharmacological therapy. Methods and results We prospectively enrolled 404 consecutive patients (mean age 70.2 ± 10 years) with ischaemic (76.5%) and non-ischaemic (23.5%) LV dysfunction (ejection fraction 34.4 ± 10.8%) and at least mild MR. Results are reported at 4 years' follow-up. Survival free of all-cause mortality was 53% and cardiac death was 74%. Survival free of all-cause mortality was 50% (95% CI 35–72) for patients with moderate MR, 49% (95% CI 27–65) for severe MR, and 64% (95% CI 47–78) for mild MR (P = 0.03). Survival free of cardiac death was 57% (95% CI 38–74) for patients with moderate MR, 55% (95% CI 30–77) for severe MR, and 94% (95% CI 59–98) for mild MR (P = 0.003). Moderate-to-severe MR [relative risk (RR) 2.7, 95% CI 1.2–6.1, P = 0.003] was an independent predictor of cardiac death but not of all-cause mortality. Survival free of heart failure (HF) was 32%. Survival free of HF was 20% (95% CI 17–35) for patients with moderate MR, 18% (95% CI 15–32) for severe MR, and 62% (95% CI 45–72) for mild MR (P = 0.0001). Moderate-to-severe MR (RR 3.2, 95% CI 1.9–5.2, P = 0.0001) was an independent predictor of HF. Conclusion The mortality and morbidity of patients with LV dysfunction and FMR remain high despite current standard pharmacological therapy. Moderate-to-severe MR is an independent predictor of cardiac death and HF.
