RESUMO

Rheumatic heart disease is in the declining phase, with the increase of urbanization and increment of availability of healthcare facility. However still it causes a substantial number of morbidity and mortality in South Asia. The prevalence of Rheumatic Fever and Rheumatic heart disease in Bangladesh is still high, 0.6 and 0.3 per thousand populations respectively. In the rheumatic process mitral is the frequently involved valve, mostly in the form of mitral stenosis. Choice of a treatment modality and its success largely depend on the accurate assessment of severity of disease especially the extent and distribution of calcification. Echocardiography has a key role in the determination of the severity of mitral stenosis as well as assessment of details calcification. Conventionally 2 dimensional and Doppler echocardiography is used. Now a days, 3D echocardiography offers better cardiac imaging for detail evaluation. The heart being a complex structure, the 3D evaluation would certainly offer better imaging for the accurate assessment of the mitral stenosis, especially details of presence & distribution calcification. This cross-sectional observational study was done from May 2012 to October 2012 in University Cardiac Centre, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. Data were collected with informed written consent, from 50 subjects who underwent transthoracic 2D and 3D Echocardiography for the assessment of rheumatic mitral valve with special emphasis on accurate assessment of severity, extent and distribution of calcification. Precise measurement of MV area is essential in the assessment of severity, which is found comparable by both 2DE (0.98±0.24cm²) and 3DE (0.92±0.23cm²). But in identifying calcification and accurate assessment of severity, more importantly commissural involvement is better detected by 3DE (p=0.002). This has extreme importance in therapeutic decision making in the treatment of chronic rheumatic MS. So, to formulate an efficient management plan, three-dimensional echocardiography has promising prospects in detecting severity & extent of rheumatic calcification.

RESUMO

Left atrial calcium (LAC) is often observed in patients who have undergone mitral valve (MV) surgery, but little is known about its characteristics and clinical implications. Therefore, we sought to investigate the structural and hemodynamic significance of LAC and its association with clinical outcomes. We investigated 327 patients with repaired or prosthetic MV who underwent cardiac CT from 2010 to 2017. The degree of LAC was analyzed and classified into three groups: group 1 (no LAC), group 2 (mild-to-moderate LAC), and group 3 (severe LAC). Clinical and echocardiographic characteristics and clinical outcomes were compared in three groups. LAC was seen in 79 (24.2%) patients. Groups 2 and 3 showed more prevalent atrial fibrillation, a rheumatic etiology, a higher number of previous surgeries, a larger LA volume index, and higher pulmonary artery systolic pressure than group 1. Paravalvular leakage of the MV increased progressively according to severity of LAC (15.4% in group 1, 39.3% in group 2, and 66.7% in group 3, p <0.001). Event-free survival rate for major adverse cardiovascular adverse events (log rank p = 0.033) and all-cause mortality (log rank p <0.001) were significantly different according to LAC group. In Cox regression analyses, presence of severe LAC was an independent predictor of all-cause mortality (hazard ratio: 4.44, 95% confidence interval: 1.71 to 11.58, p = 0.002). LAC on cardiac CT is not uncommon and reflects more advanced LA remodeling and a stiff LA. The presence and severity of LAC are associated with a worse clinical outcome after MV surgery.

RESUMO

Ortners syndrome is a rare cause of recurrent laryngeal nerve palsy due to cardiac causes. After the description of this syndrome by Ortner in patients with mitral stenosis, it was described by many authors in multiple other cardiac conditions. Here we present a case of Ortner's syndrome in Dilated cardiomyopathy,which reverted completely after medical management of DCMP.

RESUMO

A 47-year-old woman with a history of mitral valve replacement (MVR) through a median sternotomy was admitted to our hospital due to dyspnea on exertion. Echocardiography showed bioprosthetic valve dysfunction with mitral stenosis. Right heart catheter examination revealed severe pulmonary hypertension and right ventricular dysfunction. We considered that she could not tolerate the hemodynamic changes during induction of general anesthesia without any cardiopulmonary support. Therefore, the percutaneous cardiopulmonary support was started before induction of anesthesia. To avoid the risk of injury to cardiac structures, we performed redo mitral valve replacement via right mini-horacotomy in the 4th intercostal space. Severe calcification was found in the leaflets of the prosthetic valve. She was discharged home on postoperative day 42.

RESUMO

Mitral stenosis is classically caused by rheumatic disease (RMS). However, degenerative mitral stenosis (DMS) is increasingly encountered, particularly in developed countries with aging populations. The aim of this study was to compare clinical and echocardiographic characteristics between the 2 entities. One hundred fifteen patients with DMS were identified from an echocardiographic database in the United States and compared with 510 patients with RMS from Seoul, Korea. All subjects had a mitral valve area (MVA) ≤2.5 cm2 by continuity equation but were otherwise unselected. Patients with DMS were older and had more hypertension, diabetes, chronic kidney disease, and chronic obstructive pulmonary disease than those with RMS. Atrial fibrillation was more common in RMS patients. Mean mitral valve gradient was slightly lower in DMS versus RMS (7.63 ± 3.67 vs 8.50 ± 4.23 mm Hg, p = 0.04) but MVA was strikingly higher in the DMS group (1.35 ± 0.41 vs 0.95 ± 0.38 cm2, p <0.0001). This appeared to be due to greater stroke volume in the DMS patients (70.4 ± 19.7 vs 55.7 ± 15.5 ml, p <0.0001). Indexed left atrial volume was greater in RMS (82.1 ± 40.3 vs 57.9 ± 21.4 ml, p <0.0001) while estimated pulmonary artery systolic pressure was greater in DMS (49.3 ± 16.5 vs 39.4 ± 13.6 mm Hg, p <0.0001). In conclusion, DMS patients are older and have more comorbidities than RMS patients. DMS presents with greater MVA relative to mean mitral valve gradient than RMS. This appears due to a higher stroke volume in DMS patients.

RESUMO

BACKGROUND: Mitral valve stenosis in adults especially due to rheumatic heart disease may be associated with a smaller than normal left ventricular cavity. Mitral valve replacement in such cases may lead to hemodynamic instability either during weaning from cardiopulmonary bypass or in the early postoperative period manifested by the need for inotropic support and even mortality due to low cardiac output syndrome. PATIENTS AND METHODS: 184 patients with predominately severe stenotic mitral valves who underwent elective isolated mitral valve replacement in the period between January 2012 and January 2018 at our hospital were included in this study. Patients were divided into 2 matched groups; (small LV group) consisting of 86 cases and (normal or dilated LV group) consisting of 98 cases. RESULTS: There were no statistically significant differences in operative details among both groups apart from the need for inotropic support and intra-aortic balloon pump due to low cardiac output which were statistically significantly higher in (small LV group) than (normal or dilated LV group) with a p-values of 0.01 and 0.03 respectively. Within the ICU stay only the incidence of occurrence of heart failure was significantly higher in (small LV group) with a p-value of 0.008. No statistically significant difference could be elicited in the in-hospital mortality between both groups (p-value = 0.1). CONCLUSION: Patients with mitral valve stenosis and small left ventricular cavity are in a higher need for inotropic and even mechanical support after mitral valve replacement as well as at a higher risk for the development of heart failure before hospital discharge than patients with mitral stenosis and normal-sized left ventricular cavity.

RESUMO

INTRODUÇÃO: Valvotomia mitral percutânea (VMP) é o tratamento de escolha em pacientes com estenose mitral reumática. Em pacientes jovens, o implante de uma prótese pode trazer diversas complicações no curto e longo prazo como durabilidade bastante reduzida. O OBJETIVO desse trabalho é descrever os resultados imediatos e acompanhar o follow-up desse grupo de pacientes. MÉTODOS: Foram selecionados, em uma coorte retrospectiva, pacientes que se submeteram a VMP com idade menor do que 18 anos devido a estenose mitral reumática. Os procedimentos e a ecocardiografia foram realizados em centro único. RESULTADOS: 58 pacientes (15,41±2,42 anos, 69% mulheres) foram submetidos a 66 procedimentos. A área valvar prévia foi de 0,87±1,94 cm2 e após o procedimento passou a ser 2,00±0,46cm2, com 74% de insuficiência mitral graduada como menor do que discreta, 98,5% tinham ritmo sinusal e o procedimento foi considerado sucesso em 89,4%, sucesso parcial em 6,1% e insucesso 4,5%. No acompanhamento de curto prazo, 19,7% evoluíram para necessidade de cirurgia, sendo 3% emergencial. 22 casos evoluíram para necessidade de redilatação, sendo 12 casos ainda com menos de 18 anos e os demais acima dessa idade. CONCLUSÃO: A VMP é o método de escolha para o tratamento da estenose mitral reumática em pacientes abaixo de 18 anos, de mostrando segurança e bons resultados. Nessa faixa etária a prevalência em homens foram significativamente superior.

RESUMO

BACKGROUND: Mitral annular calcification (MAC) occurs represents a challenge to surgeons during mitral valve (MV) surgery with increased perioperative risk. CASE PRESENTATION: We describe a challenging case of an elderly female patient with multiple comorbidities who presented with symptoms and signs of heart failure with a previous history of mechanical aortic valve replacement 15 years prior to presentation. Echocardiogram showed severe mitral stenosis and regurgitation with severe calcification of the mitral annulus. Given her high-risk profile and unavailability of suitable percutaneous therapeutic options we decided to replace her mitral valve with Sapien 3 valve under direct exposure. The case describes the technical details for the valve implantation and demonstrates the viability of this option in high risk surgical patients without the need for adjunct techniques like predilatation, additional supporting sutures or patches with a review of the literature on open surgical implantation of Sapien 3 valve. CONCLUSION: Direct open surgical implantation of Sapien 3 valve can be implanted safely in patients with severe MAC, without predilatation and without the use of other adjunctive techniques like fixation sutures or patches.

RESUMO

BACKGROUND: The experience with cardiac magnetic resonance (CMR) in mitral stenosis (MS) is limited in contrast to mitral regurgitation. PURPOSE: To compare CMR versus 2D and 3D transthoracic (TTE) and 3D transesophgeal (TEE) echocardiography in assessment of rheumatic MS before and after percutaneous balloon mitral valvuloplasty (PBMV). MATERIAL AND METHODS: Twenty consecutive symptomatic patients with MS were evaluated prospectively and independently by CMR, TTE, and TEE pre-PBMV, and by CMR and TTE post-PBMV. Mitral valve area (MVA) was assessed by CMR planimetry, TTE and TEE planimetry, and pressure half time (PHT). Further assessment included trans-mitral velocity, mitral regurgitation (MR), and left atrial (LA) volume. RESULTS: PBMV was successful in 18 patients and failed in two patients (one with MVA <1.5 cm2, one developed severe MR). Pre-PBMV and MVA by CMR, 2D TTE, biplane, 3D TTE, 3D TEE, and PHT were 1.16, 1.16, 1.10, 1.02, 1.05, and 0.99 cm2, respectively. Post-PBMV, a significant increase in MVA was observed (2.15, 2.06, 2.07, 2.04, and 2.03 cm2, respectively). High agreement was observed between CMR and echocardiography before and after PBMV, except for PHT method. CMR significantly underestimated trans-mitral velocity and gradients compared to echocardiography (P<0.001). Before PBMV, mild MR was observed in 11, 12, and 19 patients by 2D TTE, 3D TTE, and CMR. After PBMV, MR was observed in all patients (19 mild, one severe) by all modalities. Echocardiography significantly underestimated LA volume compared to CMR (P<0.001). LA volume decreased significantly after PBMV (P<0.001). CONCLUSION: CMR provides comprehensive assessment of several parameters in MS patients before and after intervention. Agreement with echocardiography is acceptable.

RESUMO

Functional mitral stenosis after mitral valve repair for degenerative mitral regurgitation( DMR) is an evolving concept. Mitral annuloplasty devices stabilize the mitral annulus, reduce leaflet stress and increase leaflet coaptation, which leads to improvement of repair durability at the cost of dynamic and physiological annular movement and diastolic annular area. An elevation in rest and peak transmitral gradient has been observed in some patients with annuloplasty devices, and this elevation may associate with worse prognosis as late atrial fibrillation or lower functional capacity after surgery. In this review, we summarize the current reports describing functional mitral stenosis after mitral valve repair for DMR.

RESUMO

BACKGROUND: We want to compare the impact on health-related quality of life (HRQoL) between the Star GK and the SJM valve in the Chinese population. METHODS: We retrospectively enrolled a total of 172 patients who had undergone mechanical mitral valve replacement (MVR) (SJM valve in 87 patients and Star GK valve in 85 patients) at our institution from January 2013 to December 2015. We measured the sound pressure level, and used 2 self-administered questionnaires and the Chinese version of SF-36 to measure the HRQoL and valve-specific questions to evaluate patient anxiety. RESULTS: The Star GK group and the SJM group were similar in age, gender, body surface area, diameter of the implanted valve, underlying disease and current median NYHA class. Regarding the valve sound pressure perceived 1 year after operation, the SJM valve was slightly quieter than the Star GK valve, but the sound pressures of the two valves showed no significant differences. No significant differences in any of the eight subscales of the SF-36 were found between the two groups. CONCLUSIONS: The present study suggests that the Star GK valve is similar to the SJM valve in its impact on HRQoL and audibility of mechanical sound in the Chinese population.

RESUMO

BACKGROUND: Mitral annular calcification (MAC) is associated with risk of stroke. This study aimed to define the morphological and functional characteristics of MAC that are related to stroke. METHODS: A total of 460 subjects with MAC from transthoracic echocardiography in a single center from 2012 to 2016 was retrospectively reviewed. Subjects were classified into two groups according to history of stroke [Group 1 (n = 366): without stroke; Group 2 (n = 94): with stroke]. Morphological and functional features of MAC on echocardiogram were scored from 0 to 3 according to MAC mobility, presence of echodense mass with central echolucencies in the periannular region suggesting caseous necrosis, and functional stenosis. RESULTS: Significantly more patients in group 2 were men and had history of diabetes mellitus, dyslipidemia, atrial fibrillation, or infective endocarditis. Although MAC thickness and extent did not differ between the two groups, group 2 showed a considerably higher MAC score than group 1 (0.50 ± 0.77 vs. 0.23 ±0.52 p<0.001) as a result of the higher prevalence of each component in group 2 [mobility (22 vs. 11%, p = 0.003), echodense mass with central areas of echolucencies suggesting caseous necrosis (23 vs. 7%, p<0.001), and functional mitral stenosis (12 vs. 7%, p = 0.042)]. On logistic regression analysis, MAC score was independently associated with stroke and showed significant incremental value to demographic factors and comorbidities in association with stroke in a consecutive manner. CONCLUSIONS: In conclusion, morphological and functional characteristics of MAC had incremental value in association with stroke over traditional risk factors. MAC score consisting of MAC mobility, typical echodense mass with central echolucencies suggesting caseous necrosis, and functional mitral stenosis was independently associated with stroke. MAC with high-risk features may act as a source of stroke or more potent composite surrogate markers for stroke-related risk factors.

RESUMO

While the impairment of left atrial (LA) mechanics in mitral valve disease is well known, the exact onset of reservoir, conduit, and contractile dysfunction in mitral stenosis (MS) and mitral regurgitation (MR) remains unclear. We aimed to clarify the LA deformation mechanics in patients with moderate mitral valve disease. We conducted a prospective observational study of 80 patients with moderate isolated MR, 80 patients with moderate isolated MS, and 64 age-matched controls without mitral valve disease. Strain (ɛ) and strain rate (SR) on speckle tracking echocardiography were assessed as indicators of LA and right atrium (RA) reservoir (ɛsys, SRs), conduit (ɛe, SRe), and contractile (ɛa, SRa) functions. Conventional echocardiographic parameters of the left ventricle (LV) were also assessed. Comparisons were conducted according to mitral valve pathology (MR patients, MS patients, controls). The mean LV ejection fraction, end-diastolic diameter, and global longitudinal strain did not differ across the groups. The pulmonary artery systolic pressure, LA volume indexed to body surface area, and LA mechanics were significantly impaired in mitral valve disease (patients vs controls). While LA ɛ did not vary between MR and MS, MR patients had better LA SRs and SRe but worse SRa (p < 0.01). SRe > - 0.65% had higher specificity for MS, with an area under the curve of 0.85 (p < 0.01). RA mechanics were significantly impaired in mitral valve disease (patients vs controls) but did not vary significantly with disease pathology (MS vs MR). Patients with moderate mitral valve disease exhibit early and pathology-specific changes in the LA deformation mechanics, manifesting mainly as impaired contractile-phase SR in MR and impaired conduit-phase SR in MS. Our findings highlight SR as a potentially useful early marker of LA dysfunction in relation to mitral valve disease.

RESUMO

BACKGROUND: Long-term outcomes of mitral valve replacement (MVR) recipients with pulmonary hypertension (PH) remain unclear. We determined the effect of concomitant PH on the clinical outcomes and late-onset progression of tricuspid regurgitation (TR) after MVR for rheumatic mitral stenosis. METHODS: We retrospectively reviewed 394 patients who underwent MVR between January 2000 and December 2013. PH was defined as systolic pulmonary arterial pressure (sPAP) >50 mm Hg. Changes in echocardiographic parameters (preoperative to postoperative), TR progression (grade ≥ II), and long-term survival were evaluated according to the presence of PH at MVR (non-PH, n = 322; PH, n = 72). RESULTS: The 10-year overall survival rate was significantly lower in the PH group (79.7% vs 90.7%, P = .04), whereas the rate of freedom from TR progression was similar between groups (76.9% vs 80.5%, P = .373). High preoperative sPAP and right ventricular systolic pressure (RVSP) did not affect TR progression. However, substantial postoperative reductions in sPAP and RVSP protected against TR progression (hazard ratio [95% confidence interval], 0.966 [0.942-0.991], P = .008, and 0.973 [0.960-0.986], P < .001, respectively). The 10-year rate of freedom from TR progression was significantly higher in patients with substantial sPAP and RVSP reductions (sPAP, 84.2% vs 70.6%, P = .003; RVSP, 84.9% vs 71.0%, P < .001). CONCLUSIONS: Although concomitant PH at MVR is associated with poor long-term survival, adequate sPAP and RVSP reduction can prevent TR progression even in patients with severe PH preoperatively. Therefore, we suggest careful monitoring of PAP and RVSP after MVR and should make an effort to reduce postoperative PAP.
