Frequency and long term follow up of valvar insufficiency caused by retrograde aortic radiofrequency catheter ablation procedures. (1/941)

OBJECTIVE: To assess the frequency of valvar complications caused by left sided radiofrequency catheter ablation using the retrograde aortic technique. METHODS: 179 patients (118 male) with a mean (SD) age of 43 (17) years underwent 216 procedures at one centre. The target of the ablation was an accessory atrioventricular pathway in 144 patients, the atrioventricular junction in 29 patients, and a ventricular tachycardia in six patients. In 25 patients structural heart disease was identified before the procedure (ischaemic heart disease 10, cardiomyopathy nine, valvar three, other three). Echo/Doppler examinations were performed the day before the procedure and within 24 hours postablation; the investigations were all reviewed by the same investigator. Patients with identified valvar injury caused by the procedure were followed for 42 (7) months. RESULTS: Valvar injury caused by the ablation procedure was identified in four young (age 30 (8) years), otherwise healthy patients with left lateral atrioventricular accessory pathways. Mild mitral insufficiency with a central regurgitation jet was detected in two patients and remained unchanged at follow up. Mild aortic insufficiency was detected in another two patients. In one of these the regurgitation jet was central and remained unchanged at follow up. In one patient the regurgitation jet was located between the non-coronary and left cusps in relation to a loosely attached structure. Both the structure and the valvar regurgitation disappeared during follow up. No clinical complications occurred in any of the patients during follow up. CONCLUSION: In this study, the frequency of valvar complications after left sided radiofrequency catheter ablation using the retrograde aortic technique was 1.9%.  (+info)

Impact of vascular adaptation to chronic aortic regurgitation on left ventricular performance. (2/941)

BACKGROUND: This investigation was designed to test the hypothesis that vascular adaptation occurs in patients with chronic aortic regurgitation to maintain left ventricular (LV) performance. METHODS AND RESULTS: Forty-five patients with chronic aortic regurgitation (mean age 50+/-14 years) were studied using a micromanometer LV catheter to obtain LV pressures and radionuclide ventriculography to obtain LV volumes during multiple loading conditions and right atrial pacing. These 45 patients were subgrouped according to their LV contractility (Ees) and ejection fraction values. Group I consisted of 24 patients with a normal Ees. Group IIa consisted of 10 patients with impaired Ees values (Ees <1.00 mm Hg/mL) but normal LV ejection fractions; Group IIb consisted of 11 patients with impaired contractility and reduced LV ejection fractions. The left ventricular-arterial coupling ratio, Ees/Ea, where Ea was calculated by dividing the LV end-systolic pressure by LV stroke volume, averaged 1.60+/-0.91 in Group I. It decreased to 0.91+/-0.27 in Group IIa (P<0.05 versus Group I), and it decreased further in Group IIb to 0.43+/-0.24 (P<0.001 versus Groups I and IIa). The LV ejection fractions were inversely related to the Ea values in both the normal and impaired contractility groups (r=-0.48, P<0.05 and r=-0.56, P<0.01, respectively), although the slopes of these relationships differed (P<0.05). The average LV work was maximal in Group IIa when the left ventricular-arterial coupling ratio was near 1.0 because of a significant decrease in total arterial elastance (P<0.01 versus Group I). In contrast, the decrease in the left ventricular-arterial coupling ratio in Group IIb was caused by an increase in total arterial elastance, effectively double loading the LV, contributing to a decrease in LV pump efficiency (P<0.01 versus Group IIa and P<0.001 versus Group I). CONCLUSIONS: Vascular adaptation may be heterogeneous in patients with chronic aortic regurgitation. In some, total arterial elastance decreases to maximize LV work and maintain LV performance, whereas in others, it increases, thereby double loading the LV, contributing to afterload excess and a deterioration in LV performance that is most prominent in those with impaired contractility.  (+info)

Bileaflet mechanical prostheses for aortic valve replacement in patients younger than 65 years and 65 years of age or older: major thromboembolic and hemorrhagic complications. (3/941)

OBJECTIVE: To determine major thromboembolic and hemorrhagic complications and predictive risk factors associated with aortic valve replacement (AVR), using bileaflet mechanical prostheses (CarboMedics and St. Jude Medical). DESIGN: A case series. SETTING: Cardiac surgical services at the teaching institutions of the University of British Columbia. PATIENTS AND METHODS: Patients 2 age groups who had undergone AVR between 1989 and 1994 were studied. Group 1 comprised 384 patients younger than 65 years. Group 2 comprised 215 patients 65 years of age and older. RESULTS: The linearized rates of major thromboembolism (TE) occurring after AVR were 1.54%/patient-year for group 1 and 3.32%/patient-year for group 2; the rates for major TE occurring more than 30 days after AVR were 1.13%/patient-year for group 1 and 1.55%/patient-year for group 2. The crude rates for major TE occurring within 30 days of AVR were 1.04% for group 1 and 3.72% for group 2. The death rate from major TE in group 1 was 0.31%/patient-year and in group 2 was 0.88%/patient-year. Of the major TE events occurring within 30 days, 100% of patients in both age groups were inadequately anticoagulated at the time of the event, and for events occurring more than 30 days after AVR, 45% in group 1 and 57% in group 2 were inadequately anticoagulated (INR less than 2.0). The overall linearized rates of major hemorrhage were 1.54%/patient-year for group 1 and 2.21%/patient-year for group 2. There were no cases of prosthesis thrombosis in either group. The mean (and standard error) overall freedom from major TE for group 1 patients at 5 years was 95.6% (1.4%) and with exclusion of early events was 96.7% (1.3%); for group 2 patients the rates were 90.0% (3.2%) and 93.7% (3.0%), respectively. The mean (and SE) overall freedom from major and fatal TE and hemorrhage for group 1 patients was 90.1% (2.3%) and with exclusion of early events was 91.2% (2.3%); for group 2 patients the rates were 87.9% (3.1%) and 92.5% (2.9%), respectively. The 5-year rate for freedom from valve-related death for group 1 patients was 96.3% (2.1%) and for group 2 patients was 97.2% (1.2%). CONCLUSION: The thromboembolic and hemorrhagic complications after AVR with bileaflet mechanical prostheses occur more frequently and result in more deaths in patients 65 years of age and older than in patients years younger than 65 years.  (+info)

Minimally invasive aortic valve replacement through a transverse sternotomy: a word of caution. (4/941)

OBJECTIVES: To compare aortic valve replacement (AVR) using a minimally invasive approach through a transverse sternotomy with the established approach of median sternotomy. DESIGN: Retrospective, case-control study. PATIENTS: Fourteen high risk patients (median age 78, Parsonnet score of 18%) who underwent AVR performed through a minimally invasive transverse sternotomy were compared with a historical group of patients matched for age, sex, and Parsonnet score who underwent AVR performed through a median sternotomy by the same surgeon. OUTCOME MEASURES: Cross clamp time, total bypass time, intensive care stay, postoperative in-hospital stay, morbidity, and mortality. RESULTS: There were two deaths in the minimally invasive group and none in the control group (NS). The cross clamp and total bypass times were longer in the minimally invasive group (67 and 92 minutes v 46 and 66 minutes, p < 0.001). There was a higher incidence of re-exploration for bleeding (14% v 0%) and paravalvar leaks (21% v 0%) in the minimally invasive group but these differences were not significant. The minimally invasive group had a longer postoperative in-hospital stay (p = 0.025). The incidence of mortality or major morbidity was 43% (six of 14) in the minimally invasive group and 7% (one of 14) in the matched pairs (p = 0.013). CONCLUSIONS: AVR can be performed through a transverse sternotomy but the operation takes longer and there is an unacceptably high incidence of morbidity and mortality.  (+info)

Non-invasive assessment of left ventricular function after correction of severe aortic regurgitation. (5/941)

Twenty patients were studied with simultaneous left ventricular cavity echocardiograms and apex cardiograms during the first two weeks after correction of severe aortic regurgitation. Endocardial echoes and apex cardiograms were digitized, so that left ventricular dimensions, their rates of change, and echo dimension-apex cardiogram relations could be studied. After aortic valve replacement, there was an early reduction in end-diastolic dimension, within 2 days, from 7-0 +/- 0-8 cm to 5-7 +/- 1-0 cm (P less than 0-001), while peak normalized shortening rate (peak Vcf) dropped from 1-9 +/- 0-6 to 1-4 +/- 0-6 S-1 (P less than 0-01), and remained unchanged for the remainder of the study. Immediately after operation, striking abnormalities of isovolumic contraction and, to a lesser extent, of early relaxation, could be seen, which regressed over 4 to 7 days, except in 2 patients who developed a low output state. These changes in left ventricular dimension, Vcf, and isovolumic contraction could not have been described by an single "measure" of left ventricular function.  (+info)

Syphilitic aortic regurgitation. An appraisal of surgical treatment. (6/941)

During the 10 years from 1964 to 1973, fifteen patients with severe syphilitic aortic regurgitation were treated surgically at the National Heart Hospital. In thirteen the valve was replaced and in two it was repaired. In addition four had replacement of an aneurysmal ascending aorta with a Dacron graft and seven some form of plastic repair to the coronary ostia. Three patients died within 1 month of surgery and a further six during the follow-up period which varied from 1 to 55 months (mean 25-5). The six survivors have been followed-up for an average of 33 months. Factors contributing to this high mortality were analysed and it was found that the mean duration of effort dyspnoea was 22 months in the survivors compared with 48 months in those who had died. Similarly the average duration of nocturnal dyspnoea was 4 months in the survivors compared with a mean of 8 months in those who had died. Only six out of the fifteen patients had angina; this was present in two of the survivors and in four of the fatalities. The pulse pressure, heart size, and haemodynamic findings were similar in the two groups. The prognostic value of an elevated erythocyte sedimentation rate was also examined. It was concluded that preoperative investigations should include aortography, coronary arteriography, an assessment of left ventricular function, and whenever possible myocardial biopsy. These data were interpreted as suggesting that patients should be referred for surgery at an earlier stage in the disease--certainly before the onset of cardiac failure and--and that if this more aggresive attitude was adopted, as it has been in non-syphilitic cases of aortic valve disease, the present high mortality in this group would be reduced.  (+info)

Three-dimensional reconstruction of the color Doppler-imaged vena contracta for quantifying aortic regurgitation: studies in a chronic animal model. (7/941)

BACKGROUND: The purpose of this study was to investigate the use of 3-dimensional (3D) reconstruction of color Doppler flow maps to image and extract the vena contracta cross-sectional area to determine the severity of aortic regurgitation (AR) in an animal model. Evaluation of the vena contracta with 2-dimensional imaging systems may not be sufficiently robust to fully characterize this region, which may be asymmetrically shaped. METHODS AND RESULTS: In 6 sheep with surgically induced chronic AR, 18 hemodynamically different states were studied. Instantaneous regurgitant flow rates were obtained by aortic and pulmonary electromagnetic flowmeters (EMFs) as reference standards, and aortic regurgitant effective orifice areas (EOAs) were determined from EMF regurgitant flow rates divided by continuous-wave (CW) Doppler velocities. Composite video data for color Doppler imaging of the aortic regurgitant flows were transferred into a TomTec computer after computer-controlled 180 degrees rotational acquisition. After the 3D data transverse to the flow jet were sectioned, the smallest proximal jet cross section was identified for direct measurement of the vena contracta area. Peak regurgitant flow rates and regurgitant stroke volumes were calculated as the product of these areas and the CW Doppler peak velocities and velocity-time integrals, respectively. There was an excellent correlation between the 3D-derived vena contracta areas and reference EOAs (r=0.99, SEE=0.01 cm2) and between 3D and reference peak regurgitant flow rates and regurgitant stroke volumes (r=0.99, difference=0.11 L/min; r=0.99, difference=1.5 mL/beat, respectively). CONCLUSIONS: 3D-based determination of the vena contracta cross-sectional area can provide accurate quantification of the severity of AR.  (+info)

Mortality and morbidity of aortic regurgitation in clinical practice. A long-term follow-up study. (8/941)

BACKGROUND: The outcome of aortic regurgitation conservatively followed in clinical practice is poorly defined. METHODS AND RESULTS: Long-term outcome of 246 patients with severe or moderately severe aortic regurgitation diagnosed by color Doppler echocardiography was analyzed. With conservative management, mortality rate was higher than expected (at 10 years, 34+/-5%, P<0. 001) and morbidity was high (10-year rates of 47+/-6% for heart failure and 62+/-4% for aortic valve surgery). At 10 years, 75+/-3% of patients had died or had surgery and 83+/-3% had had cardiovascular events. In multivariate analysis, predictors of survival were age (P<0.001), functional class (P<0.001), comorbidity index (P=0.033), atrial fibrillation (P=0.002), and left ventricular end-systolic diameter corrected for body surface area (P=0.025). Ejection fraction was also an independent predictor of overall survival, including postoperative follow-up of surgically treated patients (P<0.001). High risk during conservative treatment, with mortality rate in excess of that expected, was noted among patients with severe, even transient, symptoms (24.6% yearly, P<0.001) but also in those with mild (class II) symptoms (6.3% yearly, P=0.02) and in asymptomatic patients with left ventricular ejection fraction <55% (5.8% yearly, P=0.03) or with end-systolic diameter normalized to body surface area >/=25 mm/m2 (7.8% yearly, P=0.004). Surgery performed during follow-up was independently associated with reduced cardiovascular mortality (adjusted hazard ratio, 0.54; P=0.048). CONCLUSIONS: Patients diagnosed with severe aortic regurgitation in clinical practice incur excess mortality and high morbidity, underscoring the serious prognosis of the disease. Surgery, which reduces cardiac mortality rates, should be considered promptly in high-risk patients.  (+info)

Background: Left ventricular end diastolic pressure could be estimated collectively using various measures of mitral valve and pulmonary venous flow velocities. In patients with aortic regurgitation, the AR velocity reflects the diastolic pressure difference between the aorta and the left ventricle. We sought to predict the left ventricular end diastolic pressure by a new Doppler index as aortic regurgitation peak early to late diastolic pressure gradient ratio.Patients and Methods: Fifty three patients with at least moderate aortic regurgitation were enrolled in this study. Physical examination, electrocardiography and echocardiography were performed one day before cardiac catheterization. The severity of AR was graded according to the recommendations of American society for echocardiography. The pressure half time, aortic regurgitation early diastolic velocity , aortic regurgitation early diastolic pressure gradient , aortic regurgitation end diastolic velocity, aortic regurgitation end diastolic

The natural history of chronic aortic regurgitation (AR) is characterized by a series of left ventricular (LV) compensatory mechanisms. Initially, the regurgitant volume is accommodated by increases in LV end-diastolic volume and compliance and associated LV hypertrophy. However, the concomitant increased wall stress results in increased afterload and, with it, more hypertrophy. Thus, chronic AR imposes both a volume and an often underappreciated pressure load on the left ventricle (1). The natural history of the condition typically includes a long plateau phase during which LV ejection performance is maintained and patients remain asymptomatic, and it is theoretically appealing that medical intervention at this point might improve outcomes, notably the need for aortic valve replacement (AVR) and the development of heart failure.. Candidate pharmacologic agents have included calcium-channel blockers, notably nifedipine, as well as beta-blockers and drugs that target the renin-angiotensin system. ...
Background: Mild aortic regurgitation (AR) is common in older adults, often attributed to aging and is considered harmless. We studied if baseline mild AR is associated with incident HF among community-dwelling adults ≥65 years in the Cardiovascular Health Study (CHS).. Methods: In the original CHS cohort, 4895 participants were free of prevalent HF at baseline, of whom 4873 had echocardiographic data on type and grade of valvular heart disease (VHD). Of these, 372 (8%) had mild AR (AR jet height to left ventricular outflow tract diameter ratio ,24%). After excluding those with moderate (n=505), moderately severe (n=36) or severe (n=16) AR, the final sample size was 4316. We used propensity scores for mild AR, estimated for each of the 4316 participants, to match 353 (95% of 372) of those with mild AR with 1048 of those without AR, thus assembling a cohort of 1401 participants who were balanced on 56 baseline traditional cardiovascular risk factors including hypertension and blood pressure, ...
Diastolic Murmurs - Aortic Regurgitation. You are listening to a typical murmur caused by aortic valve regurgitation. Aortic regurgitation is mostly seen in males, with a 3:1 ratio as compared to females. In 2/3 of cases, the regurgitation is secondary to rheumatic heart disease, and may have a component of aortic stenosis. Aortic regurgitation may also be primarily congenital or associated with syphilis infection, Marfan syndrome, or valvular deterioration due to infective endocarditis.. The murmur of aortic regurgitation is complex. The left ventricle is typically dilated secondary to extreme volume overload, as it must handle both the forward flow delivered from the left atria as well as the regurgitant flow from the aorta. This large volume of blood is ejected rapidly during systole, and an early mid-systolic flow murmur is frequently audible over the right upper sternal border with radiation into the neck.. The most notable aspect of the murmur is the diastolic sound produced as the blood ...
inproceedings{3036208, abstract = {Aims: Significant aortic regurgitation (AR) may cause left ventricular (LV) dilatation and heart failure. The aim was to quantify LV function in AR horses by tissue Doppler imaging (TDI) and two-dimensional speckle tracking (2DST). Methods: Echocardiographic examinations were performed on ten healthy horses (10{\textpm}4 years;509{\textpm}58 kg) and fourteen horses with significant AR (17{\textpm}4 years;497{\textpm}93 kg). By 2DST, global radial (SR) and longitudinal (SL) strain were measured. Regional systolic radial displacement (DRS) by 2DST and velocity (VS) by TDI were measured in the interventricular septum and LV free wall. LV end-diastolic internal diameter (LVIDd) and fractional shortening (FS) were measured from a short-axis M-mode at chordal level. Results: Seven horses showed moderate AR (LVIDd range 11.0-12.7 cm), seven severe AR (LVIDd 13.3-16.9 cm). FS, SR and SL showed no significant differences. However, SL was significantly correlated with ...
Among patients with combined aortic valve disease, patients with moderate and those with severe AS at baseline did not have significantly different event-free survival rates: patients with an aortic valve area of ,1.0 cm2 had an outcome that was comparable to those with a valve area between 1.0 and 1.5 cm2 (p = 0.57). Also the degree of AR did not have prognostic value and patients with moderate AR and those with severe AR had a similar outcome (p = 0.81).. Patients with moderate AS and moderate AR had event-free survival rates of 100 ± 0%, 75 ± 10%, 24 ± 10%, and 18 ± 9% at 1, 2, 4, and 6 years, respectively, as compared to 77 ± 8%, 53 ± 9%, 42 ± 9%, and 19 ± 8% for patients with severe AS and moderate AR; 71 ± 17%, 54 ± 20%, 36 ± 20%, and 18 ± 16% for patients with moderate AS and severe AR and 76 ± 15%, 63 ± 17%, 42 ± 21%, and 21 ± 18% for patients with severe AS and severe AR (p = 0.9) (Fig. 3). However, AV-Vel was a significant predictor of outcome allowing further risk ...

Aortic valve regurgitation it affects the valve that connects the left ventricle of the heart to the aorta, responsible for distributing blood.
Aortic regurgitation is associated with retrograde diastolic flow in the aorta. Echocardiographic quantitative analysis of the magnitude of the flow reversal is believed to provide an estimate of severity of regurgitant disease despite variations in flow profiles. The purpose of this study was to ev …
We describe a noninvasive method for determining end-systolic meridional and circumferential wall stress and left ventricular architecture as the ratio of muscle to cavity area. With this technique, which uses two-dimensional echocardiography and cuff-determined values for systolic blood pressure, we assessed wall stress and left ventricular architecture in 15 normal subjects and 15 asymptomatic patients with severe chronic aortic regurgitation at rest and after load manipulations with sublingual nitroglycerin. Resting end-systolic meridional and circumferential stress were increased in patients with aortic regurgitation (113.9 +/- 29 and 260 +/- 50.7 X 10(3) dynes/cm2) compared with those in normal subjects (85.6 +/- 15.4 and 214.1 +/- 28.4 X 10(3) dynes/cm2) (both p less than .01) and remained significantly greater after nitroglycerin. Meridional stress values obtained from two-dimensional echocardiographic studies correlated closely (r = .89) with values calculated from simultaneously ...
This study was undertaken to assess the contribution of Doppler echocardiography to the quantification of aortic valve regurgitation. Ultrasound examination was performed by recording aortic arch blood flow from the suprasternal notch. A non-invasive index of valve regurgitation was obtained by calculating the ratio between the maximal amplitude of forward flow during systole and the amplitude of retrograde flow during diastole measured at the onset of the R wave of the electrocardiogram. This index was compared with semiquantitative data derived from supravalvular aortography in 93 patients. In pure aortic regurgitation (67 patients) the results showed a high correlation coefficient between Doppler and angiographic estimates. In cases of associated aortic valve stenosis there were problems in the accurate estimation of systolic blood flow which led to global overestimation in general of the degree of regurgitation and considerable lack of precision in individual patients. But in general Doppler ...

The ventricles pump blood in a forward direction from the heart to the aorta. Normally the aortic valve prevents backflow of blood to the heart when the heart relaxes after pumping. Back flow of the blood to the ventricle during relaxation leads to a subsequent increase in left ventricular volume. This leads to an increase in systolic blood pressure which is accompanied by reflex peripheral vessel dilatation which lowers the diastolic blood pressure resulting in a wide pulse pressure. The lowering of the diastolic blood pressure reduces flow of blood to the coronaries which relies on diastolic pressure. The resultant volume overload eventually leads to heart failure.. A leak may develop gradually (over months or years) or quickly (over hours or days). Aortic regurgitation may result when the aorta enlarges, often because of high blood pressure. When the aorta is enlarged, the valve may not close completely. As a result, blood leaks backward through the valve into the heart.. Aortic regurgitation ...

Grading of chronic aortic regurgitation (AR) and mitral regurgitation (MR) by cardiovascular magnetic resonance (CMR) is currently based on thresholds, which are neither modality nor quantification method specific. Accordingly, this study sought to identify CMR-specific and quantification method-specific thresholds for regurgitant volumes (RVols), RVol indexes, and regurgitant fractions (RFs), which denote severe chronic AR or MR with an indication for surgery. The study comprised patients with moderate and severe chronic AR (n = 38) and MR (n = 40). Echocardiography and CMR was performed at baseline and in all operated AR/MR patients (n = 23/25) 10 ± 1 months after surgery. CMR quantification of AR: direct (aortic flow) and indirect method (left ventricular stroke volume [LVSV] - pulmonary stroke volume [PuSV]); MR: 2 indirect methods (LVSV - aortic forward flow [AoFF]; mitral inflow [MiIF] - AoFF). All operated patients had severe regurgitation and benefited from surgery, indicated by a ...
Aortic valve regurgitation (AR) results in left ventricle (LV) volume overload (VO) leading to its dilation and hypertrophy (H). We study a rat model of severe AR induced by puncturing one or two leaflets using a catheter. Most of our studies were conducted in male animals. Recently, we started investigating if sex dimorphism existed in the AR rat model. We observed that AR females developed as much LVH as males but morphological remodeling differences were present. A head-to-head comparison of LV morphological and functional changes had never been performed in AR males (M) and females (F) using the latest modalities in cardiac imaging by echocardiography. We performed a longitudinal study to evaluate the development of LV hypertrophy caused by chronic AR in male and female rats over 6 months. Sham-operated (sham) animals were used as controls. LV diastolic volumes (EDV) increased more over 6 months in sham males than in females (38% vs. 23% for EDV, both p | 0.01). AR resulted in significant LV

In this brief report, we describe a technique to facilitate hypothermic arrest before a redo sternotomy that is likely to require extensive dissection. This approach may be well-suited for patients with significant aortic insufficiency, as it allows control of left ventricular distention once hypothermic ventricular fibrillation ensues. The procedure entails inserting a second venous cannula through the left ventricular apex through a 7-cm left mini-thoracotomy. We used the technique successfully in a patient with a ruptured, infected ascending aortic pseudoaneurysm and severe aortic insufficiency who had undergone a previous sternotomy. ...

Aortic regurgitation (AR) is a problem of moderate but increasing frequency. Current data suggest that AR of some degree affects approximately 5% to 10% of the population and increases in frequency and severity with age (1). When severe, AR gradually leads to irreversible left ventricular (LV) dysfunction, heart failure, and death; indeed, sudden death occurs in asymptomatic patients when intrinsic myocardial dysfunction is severe, even if LV ejection fraction (EF) is normal (2). Aortic valve replacement (AVR) can reliably minimize or obviate symptoms. However, management of the asymptomatic patient is a problem. In the absence of hypertension (3), no evidence supports prophylactic drug therapy for outcome improvement (4). Inferences from observational series have led to consensus guidelines defining indications for AVR (5), but no randomized trials ever have been performed to rigorously evaluate the life-prolonging efficacy of surgery, with resulting uncertainty and controversy. Therefore, ...
This lesion though not so common as the mitral lesion is of not infrequent occurrence in children and young adults as a sequence of acute rheumatic endocarditis.
Hypertrophy (H) is an adaptive response of the heart to a hemodynamic overload. Severe left ventricular (LV) volume overload (VO) from valve regurgitations (aortic (AR) or mitral regurgitation) leads to eccentric LVH. Increased protein turnover is a major event during development of LVH and the mechanistic target of rapamycin (mTOR) is a key molecule for its control. The role of mTOR inhibition in the development of LVH using rapamycin for relatively short periods of time (days to a few weeks) has been studied in the past in pressure overload models but not in VO models. We investigated if mTOR pathway was activated during LVH development in a model of severe VO (AR) in rats and if a rapamycin treatment can slow heart remodeling in this situation. Male rats with severe AR were studied acutely at 2 days, at 8 weeks (compensated phase) and 6 months (late phase) after VO induction. mTOR complex (mTORC) 1 (ribosomal S6 protein phosphorylation) was activated early after AR induction but not later in the

Also called aortic valve regurgitation, aortic regurgitation is a condition in which the aortic valve does not close properly between each heartbeat. This causes some of the blood that was being pumped out of the heart to leak back into the heart. It typically takes a prolonged period of time for a person to develop symptoms, which may include fatigue and shortness of breath.. ...
The Ross procedure offers excellent short-term outcome but the long-term durability is under debate. Reinterventions and follow-up of 100 consecutive patients undergoing Ross Procedure at our centre (1993-2011) were analysed. Follow-up was available for 96 patients (97%) with a median duration of 5.3 (0.1-17.1) years. Median age of the patient cohort was 15.2 (0.04-58.4) years with 76 males. 93% had underlying congenital aortic stenosis. Root replacement technique was applied in all. The most common valved conduits used for reconstruction of the right ventricular outflow tract were homografts (66 patients) and bovine jugular vein (ContegraR) graft (31 patients ...
Dr. Werner responded: Long course. If the ar is acute (eg due to infection or trauma), the problem is urgent. Otherwise, there is a period of many decades in which it should be monitored. Mild ar may never cause symptoms or require treatment. Serial echocardiograms done over the years will determine if the ar is leading to harm. Treatment is replacement of the aortic valve. |a href=/topics/amlodipine track_data={

Aortic Valve Regurgitation is an abnormality of the aortic valve that allows blood to flow backwards through the valve. The aortic valve normally allows blood to pass from the left ventricle into the aorta. From the aorta blood flows to the rest of the body. In aortic valve regurgitation, blood that is supposed to flow up through the aorta flows backward through the valve into the left ventricle of the heart.. ...

Sixty-six patients (27.7%) had a bicuspid valve. Aortic valve repair techniques included sub-commissural plasty in 138 patients, plication in 84, free-edge reinforcement in 80, resection of raphe plus re-suturing in 40 and the chordae technique ...
Introduction and objectives. Patients with aortic valve disease and a dilated ascending aorta are usually treated with a composite graft comprising a valve and conduit. We review here the results of treatment with an aortic root homograft as a valid alternative. Patients and method. Twenty-two consecutive patients with a mean age of 64.8 (8.8) years were studied. Mean ascending aorta dilation was 54.55 mm, aortic valve insufficiency was present in 16 patients, and a combined lesion was present in 6. In all cases a cryopreserved aortic root homograft was used to replace the aortic valve and ascending aorta. In 9 cases a Dacron conduit was used beyond the sinotubular junction to restore continuity between the homograft and the native aorta. Results. All patients survived surgery. One patient had postoperative systemic inflammatory response syndrome and one patient was re-explored for excessive bleeding. Mean duration of follow-up was 12.1 months (range 2-36 months). No patient was given ...

Previously, diagnosis was usually done through autopsy.[2] Advances in imaging technologies allow for early detection and thus ample treatment and monitoring of the affected patient. A short-axis ultrasound of the aortic valve allows for the best view of the aortic valve, and gives a clear indication of the adduction pattern of the aortic valves.[4] If an X shape is seen, then the patient can be diagnosed with having a quadricuspid aortic valve. A transthoracic echocardiogram (TTE) indicates if there is an aortic regurgitation, but a 3-D transesophageal echocardiogram can give a better view of the aortic valve.[7] Multidetector coronary CT angiography has been indicated as a single competent diagnostic imaging tool capable of delineating valvular anatomy, severity of regurgitation, and high risk coronary problems.[6] ...

Through use of the David Procedure, Valley has significant experience performing aortic valve repair for aortic regurgitation and aneurysms associated with leaking aortic valves (also known as aortic insufficiency). Aortic valve repair offers many advantages over aortic valve replacement.
Quadricuspid aortic valve (QAV) is a rare congenital anomaly frequently associated with other anomalies particularly coronary anomalies. It may be detected on transthoracic or transesophageal echocardiography. We present here a case report of a 27-year-old male patient with a QAV, the valve being regurgitant and requiring aortic valve replacement. It has been reported as isolated case reports in the literature and various theories exist to the development of QAV. The diagnosis requires a high degree of suspicion and a detailed assessment, and if asymptomatic, then patients need to be carefully followed up for the development of aortic regurgitation ...
This is a retrospective cohort analysis of more than 500 patients undergoing the David I procedure. They specifically looked into the outcome of 50 patients with bicuspid aortic valve undergoing this procedure. While the freedom from reoperation was not different between the two groups, the freedom from reoperation at 10 years was 79% in bicuspid valve patients. Unfortunately, the authors cannot provide markers of success for the David I procedure in patients with bicuspid valves, like geometric findings of the valve prior to reconstruction. However, these results are very encouraging for valve repair success in patients with bicuspid aortic valves.. ...
From a surgical perspective, the orientation of bioprosthetic aortic valves was never much of a question. Under direct visualization, the valve can be placed quite easily in an anatomic orientation. When the coronary ostia are located in their normal positions, separated by 120°, such orientation allows the surgeon to achieve the greatest distance between ostia and valve posts. Offsetting the valve orientation from normal makes sense only when the coronary ostia have aberrant origins, such as an 180° separation, in cases in which normal positioning of the valve would cause 1 post to lie in front of 1 of the coronary ostia.. For transcatheter valves, similar orientation becomes more difficult and is the subject of the study by Fuchs et al. (1) in this issue of JACC: Cardiovascular Interventions. The authors asked 2 questions: 1) how often are surgical and transcatheter aortic valve replacement (TAVR) valves placed in alignment with native aortic valve commissures; and 2) does the alignment ...

Aortic Regurgitation, (also known as Aortic Insufficiency; AI), is the failure of the aortic valve to close completely during diastole which causes blood to flow from the aorta back into the left ventricle. Aortic Regurgitation (AR) is a frequent cause of both disability and death due to congestive heart failure, primarily in individuals forty or older, but can also occur in younger populations.. Traditionally management of aortic regurgitation has been by aortic valve replacement, however, as has been observed in patients who have had mitral valve repair, the option of maintaining ones native aortic valve versus a replacement, either bioprosthetic or mechanical, can have added multiple benefits. The advantage of repair is the avoidance of prosthetic valve-related complications with bioprosthetic valves over 10-15 years or the need for anticoagulation with mechanical valves and the related problems of this therapy. ...
The aortic valve can become leaky due to a problem with the valve itself or with the first part of the aorta called the aortic root. Approximately half of the causes of aortic regurgitation are due to this aortic root being dilated. The cause of the aortic root dilation is idiopathic in most cases but can otherwise result from high blood pressure, ageing or a weakness in the aortic wall. In bicuspid aortic valves (from birth) the aortic valve itself can become weaker. Connective tissue disorders such as Marfans and ankylosing spondylitis are also associated with aortic regurgitation.. ...

Hi Everyone! My name is Amy and I am 31 years old. My sister, Karen, has already posted here. Growing up, I was told that I had an innocent heart murmur. No big deal, right? Fast forward to January 2004. My daughter, Gianna, was 5 months old. I had a gall bladder attack and decided to see the doctor. At the appointment, the doctor asked Do you know you have a heart murmur? Oh yes....its innocent, I answered. He sent me for an echo. Turns out I had a bicuspid aortic valve with severe aortic insufficiency and an aortic root dilation measuring over 5. I needed my valve and aortic root replaced right away. The decision to choose a mechanical valve was very easy for me. I was more scared than I had ever been in my life, and the thought of a second open heart surgery anytime soon was just more than I could handle. But more importantly, I had my daughter to think about. This wonderful, perfect child, whom I love more than I could ever imagine loving anybody else, needs me. Not just to feed her and ...

AORTIC VALVE FUNCTION. The functional status of QAV is predominantly a pure AR[4,12], i.e., AR in QAV is more common than aortic stenosis[4], even though its primary incompetency may develop into subsequent stenosis at a later stage[1]. Tutarel & Westhoff-Bleck[13] reported that the functional status of QAV was regurgitant in 74.7%, combined stenosis and regurgitation in 8.4%, stenotic in 0.7%, and normally functioning in 16.2%. Yotsumoto et al.[14] reported that, among 616 patients for an aortic valve operation, 9 (1.46%) patients had a QAV, all of whom had significant AR except one with combined aortic stenosis and mild AR. They also found 55.6% (5/9) of the AR patients had a cusp fenestration. Janssens et al.[15] reported that AR was present in 56% (39/70) of the patients with a QAV. Tsang et al.[2] described that 23% of the patients with a QAV had progression of AR during a mean follow-up of 5.5±3.7 years, and an association between morphological characteristics of QAV and severity of AR ...
A combination of left ventricular volumetric quantification and phase-contrast imaging performed at level of ascending aorta, however, allows accurate and reproducible assessment of mitral regurgitation. In the presence of regurgitation, the difference in cardiac output between the left ventricle and ascending aorta yields the regurgitation volume. Regurgitation fraction is calculated by normalizing the regurgitation volume to the left ventricular stroke volume. Use of regurgitation fraction should be recommended as this parameter has the advantage to be relatively insensitive to concomitant other valve abnormalities. Regurgitation fraction limits for mitral and aortic regurgitations have been estimated by using cardiac MRI: mild ≤ 15%; moderate 16-25%; moderate-severe 26-48%; severe , 48%.. ...

To date, decision making around timing of surgery in younger and smaller patients has been hindered by a lack of age- or size-specific guidelines. In the current study, an ESV z-score ,4.5, or an ESV index of ,65 ml/m2 carried a low risk of post-operative LV dysfunction. These ESV cutoffs predicted LV dysfunction with a greater degree of sensitivity than the cutoffs in the current American Heart Association/American College of Cardiology guidelines (1) and, together with the risk score combining the FPI, represent an enhancement in the assessment of risk in smaller patients with severe AR.. The FPI was independently associated with LV dysfunction after operation. This finding can be explained within the conceptual framework of afterload mismatch and pre-load reserve (2). Elevated pre-load and afterload stimulate myocardial remodeling. Myofibers increase in length and width, thus normalizing end-diastolic and ES fiber stress. As the disease progresses, remodeling fails to normalize myofiber load. ...

The center volume had a significant ...
Aortic pathology can have devastating consequences with significant morbidity and mortality. Marfan syndrome patients have a profound predisposition to develop aortic root pathology and can develop complications of aortic root pathology such as aneurysm of the aorta (especially the aortic root), aortic dissection and aortic valve regurgitation. Recent advances in understanding the pathophysiology of the consequences of fibrillin-1 deficiency in Marfan syndrome and the development of murine models of this condition have opened up the possibility for translational research to be conducted in this area. Potential pharmacological treatments can now be extensively researched prior to clinical trials.
