RESUMEN
Shone's syndrome (SS) is a rare congenital cardiac anomaly characterized by a spectrum of developmental abnormalities. It predominantly presents as consisting of a variety of left ventricular inflow and outflow tract lesions, with inflow tract lesions typically including parachute mitral valve and supravalvular mitral ring. However, reports of SS involving double-orifice mitral valve are scarce.

OBJECTIVE: A significant number of individuals with mild mitral stenosis (MS) experience exertional symptoms that are disproportionate to the hemodynamic severity of their condition. This study aims to determine whether exercise-induced left atrial (LA) dysfunction occurs in these patients and whether it is related to the development of symptoms. METHODS: In this observational study, we recruited 46 patients with mild MS. Echocardiographic measurements were initially taken at rest, followed by a maximal exercise stress test. Patients were then returned to the echocardiography laboratory for post-exercise measurements. RESULTS: Our study cohort exhibited considerably higher left atrial volume index (LAVI) values (mean: 40.52 ± 18.27) compared to those of a healthy population. Furthermore, the LA reservoir strain (mean: 17.1 ± 8.33) was reduced relative to reference values. Following exercise, there was no change in the LA reservoir strain. However, trans-mitral pressure gradients and systolic pulmonary artery pressures increased. The post-exercise mean trans-mitral gradient was identified as the sole predictor of symptom development in patients with mild MS. CONCLUSION: The LA reservoir strain is already reduced in individuals with mild MS, and exercise does not lead to further decline in LA reservoir function in these cases. To our knowledge, this study is the first to explore the effects of exercise on LA mechanics in MS.

AIMS: This study assessed the outcomes of concomitant mitral valve disease and severe aortic stenosis in patients undergoing transcatheter aortic valve replacement (TAVR). METHODS: Echocardiographic data of 813 patients with severe aortic stenosis undergoing transfemoral TAVR were collected, and clinical outcomes were analyzed for individuals with mitral stenosis and mitral regurgitation. RESULTS: The final cohort includes 788 patients with severe calcific aortic stenosis. Among single parameters of mitral stenosis, a smaller baseline mitral valve area (MVA) by the continuity equation and higher postprocedural mean mitral gradients (MMG) were associated with an increased risk of death at 1 year (P-values 0.02 and <0.01, respectively), but no correlation with outcomes was demonstrated after multivariate adjustment for major prognosticators. Mitral stenosis (based on MVA + MMG) was not associated with complications or mortality. Mitral regurgitation was present in 94.6% of the population at baseline and regressed by at least one grade post-TAVR in 28% of the patients. The improvement in mitral regurgitation was associated with a greater prosthetic effective orifice area (P-value 0.03). Significant (at least moderate) residual mitral regurgitation was correlated with short-term complications and shown to be an independent predictor of 1-year mortality (P-value 0.02, odds ratio (OR) 5.37, confidence interval 1.34-21.5). CONCLUSION: Mitral regurgitation has a greater impact on TAVR patients than mitral stenosis as assessed by functional methods.

BACKGROUND: Rheumatic heart disease is a major cause of cardiovascular morbidity and mortality in developing nations and is a leading cause of hospital admission due to cardiac problems in our country. This study will evaluate the association between left atrial size and the occurrence of atrial fibrillation and describe the clinical characteristics along with complications related to Rheumatic Mitral valve disease. METHODS: A retrospective cross-sectional study was conducted at a tertiary care center from January 2018 to December 2019. Reports of 207 patients admitted to medical and/or surgical wards with echocardiographic diagnosis of rheumatic mitral valve disease with or without atrial fibrillation were reviewed. Data were collected, entered, and analyzed using the Statistical Package for the Social Science version 25.0. RESULTS: Among 207 patients, atrial fibrillation was present in 90 (43.5%) patients. Atrial fibrillation was higher in patients with mixed mitral valvular lesions compared to isolated mitral stenosis or mitral regurgitation. Univariate and multivariate analysis revealed left atrial size [aOR=1.067, 95% CI: 1.023 - 1.113, P= 0.002] and age [aOR = 1.073, 95% CI: 1.042 - 1.105, P<0.001] as an independent predictor of atrial fibrillation. CONCLUSIONS: Larger left atrium was an independent predictor of atrial fibrillation. Besides this, atrial fibrillation was associated with increasing age, mixed mitral valvular lesion, and moderately reduced left ventricular ejection fraction, but not associated with gender and mitral stenosis severity. Left atrial clot was significantly higher in patients with atrial fibrillation than in sinus rhythm.

BACKGROUND: Mitral annulus calcification (MAC) represents a degenerative process resulting in calcium deposition in the mitral valve apparatus. Mitral annulus calcification is associated with adverse clinical outcomes. We sought to examine the long-term significance of mild MAC and its relationship to subsequent mitral valve dysfunction (MVD) and mortality in patients without MVD on the initial echocardiogram. METHODS: A total of 1,420 patients with mild MAC and no MVD at baseline and 1 or more follow-up echocardiograms at least 1 year after the baseline echocardiogram were included in the analysis. For patients with >1 echocardiogram during follow-up, the last echocardiogram was used. The same criteria were used to identify 6,496 patients without MAC. Mitral valve dysfunction was defined as mitral regurgitation (MR) and/or mitral stenosis (MS) of moderate or greater severity. Mixed disease was defined as the concurrent presence of both moderate or greater MS and MR. The primary end point was development of MVD, and the secondary end point was all-cause mortality. RESULTS: For patients with mild MAC, age was 74 ± 10 years and 528 (37%) were female. Over a median follow-up of 4.7 (interquartile range, 2.7-6.9) years, 215 patients with mild MAC developed MVD, including MR in 170 (79%), MS in 37 (17%), and mixed disease in 8 (4%). In a multivariable regression model compared to patients without MAC, the presence of mild MAC was independently associated with increased mortality (hazard ratio = 1.43; 95% CI 1.24, 1.66; P < .001). Kaplan-Meier 4-year survival rates were 80% and 90% for patients with mild MAC and no MAC, respectively. CONCLUSIONS: Mild MAC observed on transthoracic echocardiography is an important clinical finding with prognostic implications for both valvular function and mortality.

BACKGROUND: Mitral stenosis/aortic atresia (MS/AA) has been reported as a high-risk variant of hypoplastic left heart syndrome (HLHS), potentially related to ventriculocoronary connections (VCCs) or endocardial fibroelastosis (EFE) and myocardial hypoperfusion. We aimed to identify echocardiographic and clinical factors associated with early death or transplant in this group. METHODS: Patients with HLHS MS/AA treated at our center between 2000 and 2020 were included. Pre-stage I palliation echocardiograms were reviewed. Certain imaging factors, such as determination of VCC, EFE, and measurement of tricuspid annular plane systolic excursion were measured from retrospective review of preoperative images; others were derived from clinical reports. Groups were compared according to primary outcome of death or transplant prior to stage II palliation. RESULTS: Of 141 patients included, 39 (27.7%) experienced a primary outcome. Ventriculocoronary connections were identified in 103 (73.0%) patients and EFE in 95 (67.4%) patients. Among imaging variables, smaller ascending aorta size (median, 2.2 [interquartile range (IQR) 1.7-2.8] vs 2.6 [2.2-3.4] mm, P = .01) was associated with primary outcome. There was similar frequency of VCC (74.4% vs 72.5%, P = .83), EFE (59.0% vs 72.5%, P = .19), moderate or greater tricuspid regurgitation (5.1% vs 5.9%, P = 1.00), and similar right ventricular systolic function (indexed tricuspid annular plane systolic excursion 32.5 ± 7.3 vs 31.4 ± 7.2 mm/m2, P = .47) in the primary outcome group compared to other patients. Clinical factors associated with primary outcome included lower birth weight (mean, 2.8 ± SD 0.8 vs 3.3 ± 0.5 kg, P = .0003), gestational age <37 weeks (31.6% vs 4.9%, P < .0001), longer cardiopulmonary bypass time (median, 112 [IQR, 93-162] vs 82 [71-119] minutes, P = .001), longer intensive care unit length of stay (median, 19 [IQR, 10-30] vs 10 [7-15] days, P = .001), and extracorporeal membrane oxygenation following stage I palliation (43.6% vs 8.8%, P < .0001). Presence of VCCs and EFE was not associated with death or transplant after controlling for birth weight and era of stage I palliation. CONCLUSIONS: In one of the largest reported single-center cohorts of HLHS MS/AA, there were few pre-stage I palliation imaging characteristics associated with primary outcome. Imaging findings evaluated in this study, including the presence of VCC and/or EFE as determined using highly sensitive echocardiogram criteria, should not preclude intervention, although impact on long-term outcomes requires further evaluation.

BACKGROUND: Campotodactyly-artrhropathy-coxa vara-pericarditis (CACP) syndrome is a very rare autosomal recessive genetic disorder. It is characterized by flexion contracture of the fifth finger (camptodactyly); noninflammatory arthropathy; decreased angle between the shaft and the head of the femur (coxa vara) and pericarditis. Its association with mitral stenosis has not yet been reported. Hereby we report this unique association with CACP syndrome. CASE: An eleven-year-old girl presented with non-productive cough, dyspnea, and orthopnea. She was diagnosed CACP syndrome at the age of seven and a biallelic frameshift mutation in the PRG4 gene was determined. The physical examination revealed pectus excavatum, camptodactyly, genu valgum, tachypnea and orthopnea. The functional capacity was NYHA III-IV. She had 2/6 soft pansystolic murmur at 4th left intercostal space and a rumbling diastolic murmur at apex. Echocardiography revealed an enlarged left atrium, severe stenotic mitral valve with a mean diastolic transmitral gradient of 22.5 mmHg, mild mitral regurgitation and mild apical pericardial effusion. The patient had mitral comissurotomy and partial pericardiectomy operation. Her post-operative transmitral gradient decreased to 6.9 mmHg and the pulmonary pressure was 30 mmHg. Her functional capacity increased to NYHA I-II. CONCLUSIONS: The main defect is the proteoglycan 4 protein which acts like a lubricant in articular and visceral surfaces. Therefore, the leading clinical feature is arthropathy. Cardiac involvement other than clinically mild pericarditis is not usually expected. Three types of proteoglycans (decorin, biglycan, and versican) are present in the mitral valve. This could be the reason of mitral valve involvement in rare cases as like ours. It is important that these patients undergo echocardiographic examination regularly.

INTRODUCTION AND OBJECTIVE: Mitral stenosis (MS) is one of the most frequently observed valvular heart lesions in developing countries and is due to different etiologies. The effects of anticoagulation in different types of left atrial appendage (LAA) are unknown. The current study aimed to determine the resolution of LAA thrombus on transesophageal echocardiography (TEE) after three months of optimal anticoagulation in patients with different types of LAA at baseline cardiac computed tomography of patients with severe MS. METHODS: This prospective cohort study observed the frequency of LAA thrombus resolution after three months of anticoagulation therapy in patients with severe MS. The response rate in different morphologies of LAA and locations was also assessed. Thrombus resolution after three months of warfarin therapy was assessed on repeat TEE. RESULTS: A total of 88 patients were included, mean age 37.95±11.87 years. Repeat TEE showed thrombus resolution in only 27.3% of patients. The rate of thrombus resolution was 8/12 (66.7%), 4/28 (14.3%), 8/36 (22.2%), and 4/12 (33.3%) for patients with cactus, cauliflower, chicken wing, and windsock LAA type, respectively. The resolution rate was 0/12 (0%), 4/44 (9.1%), and 20/32 (62.5%) for patients with thrombus in the base, body, and tip of the LAA, respectively. CONCLUSION: The cactus type of LAA morphology and thrombus at the LAA tip responded well to three months of anticoagulation, however, patients with thrombus in the LAA base and body and cauliflower and chicken wing morphology were non-responders and could benefit from early referral for surgical management.

OBJECTIVES: To assess the impact of concomitant mitral stenosis (MS) on early and late outcomes of transcatheter aortic valve replacement (TAVR) for aortic stenosis. METHODS: This study involved 952 patients undergoing TAVR for severe tricuspid aortic stenosis. The patients were classified into 3 groups: without MS, with progressive MS, and severe MS (mitral valve area ≤ 1.5 cm2). Clinical outcomes between these groups were compared. RESULTS: The median age of the overall cohort was 82 years, and patients in the progressive (n = 49) and severe (n = 24) MS groups were more likely to be female than those in the no-MS group (n = 879). Periprocedural mortality rate was lowest in the no-MS group (1.8%) compared with the progressive (4.1%) and severe (4.2%) MS groups, which were not significantly different (P = .20). During 5 years of follow-up (median: 27, range: 0-72 months), there was no significant difference in all-cause mortality (log-rank P = .99), a composite of all-cause mortality or rehospitalization for heart failure (log-rank P = .84), or cardiovascular death (log-rank P = .57) between groups. Although crude analysis showed a significant difference in rehospitalization for heart failure in the severe MS group compared with the no-MS group (P = .049), the difference was not significant in the multivariate analysis (adjusted hazard ratio: 1.36 [95% CI, 0.66-2.80], P = .41). CONCLUSIONS: TAVR can be safely performed in patients with severe tricuspid aortic stenosis and concomitant MS, with early and mid-term outcomes comparable to those in patients without MS.

It is not uncommon for congenital heart defects to occur in clusters. Those involving a right to left heart shunt commonly cause cyanosis and finger clubbing. Differential clubbing involving only the lower limb digits is a strong pointer to the presence of patent ductus arteriosus with reversal of shunt. We report a case of 25-year-old man with effort intolerance and differential clubbing. He was found to have the uncommon triad of patent ductus arteriosus, ventricular septal defect and supravalvular ring mitral stenosis. The presence of differential clubbing on a background of patent ductus arteriosus usually indicates a reversal of shunt and negates surgical intervention. This general rule may however not apply with co-existing mitral stenosis as the elevated pulmonary pressure may be predominantly post-capillary. The finding of mitral stenosis in a patient with patent ductus arteriosus and differential limb clubbing may signify a good prognostic surgical outcome.
Il n'est pas rare que des malformations cardiaques congénitales surviennent en clusters. Celles impliquant un shunt cardiaque droitegauche provoquent souvent une cyanose et un hippocratisme digital. L'hippocratisme digital différentiel touchant uniquement les orteils des membres inférieurs est un indicateur fort de la présence d'un canal artériel persistant avec inversion du shunt. Nous rapportons le cas d'un homme de 25 ans présentant une intolérance à l'effort et un hippocratisme digital différentiel. Il a été diagnostiqué avec la triade peu commune de canal artériel persistant, de communication interventriculaire et de sténose mitrale à anneau supravalvulaire. La présence d'un hippocratisme digital différentiel sur un fond de canal artériel persistant indique généralement une inversion du shunt et exclut une intervention chirurgicale. Cependant, cette règle générale peut ne pas s'appliquer en présence d'une sténose mitrale concomitante, car la pression pulmonaire élevée peut être principalement post-capillaire. La découverte d'une sténose mitrale chez un patient atteint de canal artériel persistant et d'un hippocratisme digital différentiel peut indiquer un bon pronostic pour l'intervention chirurgicale.

BACKGROUND: Aortic valve calcium score is associated with hemodynamic severity of aortic stenosis. Whether this association is present in calcific mitral stenosis remains unknown. METHODS AND RESULTS: This study was a retrospective analysis of consecutive patients with mitral stenosis secondary to mitral annular calcification (MAC) undergoing transseptal catheterization. All patients underwent invasive mitral valve assessment via direct left atrial and left ventricular pressure measurement. Computed tomography within 1 year of cardiac catheterization and with adequate visualization of the mitral annulus was included. MAC calcium score quantification by Agatston method was obtained offline using dedicated software (Aquarius, TeraRecon, V.4). Median patient age was 66.9±11.2 years, 47% of patients were women, 50% had coronary artery disease, 40% had atrial fibrillation, 47% had prior cardiac surgery, and 33% had prior chest radiation. Median diastolic mitral valve gradient was 9.4±3.4 mm Hg on echocardiography and 8.5±4 mm Hg invasively. Invasive median mitral valve area using the Gorlin formula was 1.87±0.9 cm2. Median MAC calcium score for the cohort was 7280±7937 Hounsfield units. MAC calcium score correlated with the presence of atrial fibrillation (P=0.02) but was not associated with other comorbidities. There was no correlation between MAC calcium score and mitral valve area (r=0.07; P=0.6) or mitral valve gradient (r=-0.03; P=0.8). CONCLUSIONS: MAC calcium score did not correlate with invasively measured mitral valve gradient and mitral valve area in patients with MAC-related mitral stenosis, suggesting that calcium score should not be used as a surrogate for invasive hemodynamic parameters.

Double orifice mitral valve (DOMV) is an extremely rare congenital anomaly of the mitral valve (MV) wherein the MV orifice divides into two separate orifices by an accessory fibrous band.Isolated DOMV is a rarity and is often discovered incidentally. It may be associated with other congenital conditions wherein it is identified in early childhood. Its prevalence and prognostic relevance in adulthood remain unclear. DOMV patients may be asymptomatic or have symptoms due to mitral stenosis or regurgitation. We present a case of an asymptomatic young adult initially diagnosed with rheumatic mitral stenosis. However, after a thorough echocardiographic assessment, including three-dimensional transesophageal echocardiography, the accurate diagnosis of DOMV was made.

PURPOSES: Predicting hemodynamic changes of stenotic mitral valve (MV) lesions with mitral annular calcification (MAC) following transcatheter aortic valve implantation (TAVI) may inform clinical decision-making. This study aimed to investigate the association between the MAC severity quantified by computed tomography (CT) and changes in mean transmitral gradient (mTMG), mitral valve area (MVA) and stroke volume index (SVi) following TAVI. METHODS AND RESULTS: A total of 708 patients (median age 81, 52% male) with severe aortic stenosis (AS) underwent pre-procedural CT and pre- and post-TAVI transthoracic echocardiography. According to the classification of MAC severity determined by CT, 299 (42.2%) patients had no MAC, 229 (32.3%) mild MAC, 102 (14.4%) moderate MAC, and 78 (11.0%) severe MAC. After adjusting for age and sex, there was no significant change in mTMG following TAVI (Δ mTMG = 0.07 mmHg, 95% CI -0.10 to 0.23, P = 0.92) for patients with no MAC. In contrast, patients with mild MAC (Δ mTMG = 0.21 mmHg, 95% CI 0.01 to 0.40, P = 0.018), moderate MAC (Δ mTMG = 0.31 mmHg, 95% CI 0.02 to 0.60, P = 0.019) and severe MAC (Δ mTMG = 0.43 mmHg, 95% CI 0.10 to 0.76, P = 0.0012) had significant increases in mTMG following TAVI, with greater changes associated with increasing MAC severity. In contrast, there was no significant change in MVA or SVi following TAVI. CONCLUSION: In patients with severe AS undergoing TAVI, MAC severity was associated with greater increases in post-procedural mTMG whereas MVA or SVi remained unchanged. MAC severity should be considered for potential subsequent MV interventions if TAVI does not improve symptoms.

Concomitant mitral stenosis (MS) is present in 10% to 15% of all patients who underwent transcatheter aortic valve replacement (TAVR). Our aim is to assess outcomes of TAVR in patients with MS using a national database. The Nationwide Inpatient Sample database was used to identify patients who underwent TAVR from 2015 to 2020. We created 2 groups, patients with and those without MS. We then compared baseline characteristics, demographics, and in-hospital outcomes of the groups. Primary outcomes were in-hospital mortality, acute respiratory failure, and pacemaker placement. Secondary outcomes were length of stay and in-hospital costs. Our study indicates that patients with MS had greater incidence of acute respiratory failure (8.8% vs 4.89%, p = 0.001), complete heart block (13.54% vs 9.36%, p = 0.01), and permanent pacemaker placement (8.03% vs 6.03%, p = 0.05). In-hospital mortality was greater in the MS group; however, it was not statistically significant (1.32% vs 1.53%, p = 0.679).
