Relationship between New York functional class and duke activity status index with the severity of mitral valve stenosis and echocardiographic parameters: is left atrial strain a better predictor?

Purpose This study aimed to investigate the relationship between symptoms of patients with severe mitral stenosis (MS), evaluated by the New York Heart Association (NYHA) functional class and Duke Activity Status Index (DASI) score, and echocardiographic parameters. We evaluated patients with severe rheumatic MS diagnosed as mitral valve area (MVA) less than 1.5 cm2. All patients underwent transthoracic echocardiography and the left atrium (LA) reservoir auto-strain (LASr) analysis. In addition, DASI and NYHA scores were determined to evaluate the functional capacity and symptoms of MS patients. We evaluated 60 patients with MS with a mean age of 50.13 ± 10.28 and a median DASI score of 26.95 (26.38). There were 6 (10%) and 28 (46.7%) patients with NYHA class I and II, and 25 (40.0%) and 2 (3.3%) patients with NYHA class III and IV, respectively. NYHA class was positively correlated with LA area (LAA, r = 0.638), LA volume (LAV, r = 0.652), LAV index (LAVI, r = 0.62), E (r = 0.45), A (r = 0.25), and pulmonary artery pressure (PAP, r = 0.34), while negatively correlated with LASr (r = - 0.73) and MVA (r = - 0.417). Furthermore, the DASI score was positively associated with LASr (r = 0.81) and MVA (r = 0.52) while negatively correlated with LAA (r = - 0.62), LAV (r = - 0.65), LAVI (r = - 0.56), E (r = - 0.46), A (r = - 0.3), and PAP (r = - 0.32). Our findings indicate that LAA, LAV, LAVI, E, A, PAP, MVA, and LASr are associated with NYHA and DASI scores in MS patients. Additionally, the LASr had the strongest correlation between all measured parameters in severe MS patients.

Novel echocardiographic parameters in pulmonary hypertension assessment and the relationship between echocardiography and 6-minute walking test.

Pulmonary artery stiffness (PAS) has been shown to be related to pulmonary artery pressure in patients with pulmonary artery hypertension (PAH). The aim of this study was to determine the correlation between functional capacity and echocardiographic indices of PAS in patients with PAH. This cross-sectional study was performed on patients with PAH who were confirmed by right heart catheterization and referred to Imam Reza PAH clinic for routine follow-up between November 2019 and January 2020. All patients underwent echocardiography and the maximum Doppler frequency shift, pulmonary acceleration time, peak velocity of the pulmonary flow, and velocity time integral, as well as PAS, were measured. All patients performed a 6-minute walk test. Fifty patients with a mean age of 41.90 ±â€…14.73 years old participated in this study. The majority of the patients were female (74%). The most common cause of PAH was idiopathic (74%). There was a significant correlation between PAS and pulmonary artery systolic pressure (r = 0.302, P = .041), second pulmonary valve pulse Doppler velocity (V2) (r = -0.461, P = .003), time from onset of pulmonary flow ejection to V2/first pulmonary valve pulse Doppler velocity (r = -0.311, P = .037) and Z3 ratio (r = -0.346, P = .023). There was no significant correlation between PAS and 6-minute walk test, pulmonary vascular resistance, and tricuspid annular plane systolic excursion (P > .05). There was a significant correlation between V2 and pulmonary vascular resistance (r = 0.359, P = .049). PAS and first pulmonary valve pulse Doppler velocity are simple, noninvasive, available tools for the evaluation of pulmonary vascular beds and diagnosis of presymptomatic clinical status in patients with PAH.

Unrepaired tetralogy of Fallot in a 71 years old woman: A case report and review of the literature.

Tetralogy of Fallot (ToF) is the most common cyanotic congenital heart disease (CHD) in infants. The four components that constitute ToF are an overriding aorta over the crest of the interventricular septum, obstruction in the right ventricular outflow tract, right ventricular hypertrophy, and a typically large non-restricted ventricular septal defect. ToF may also be associated with other extracardiac abnormalities, including patent ductus arteriosus or multiple aortopulmonary collateral arteries, which can impact the patient's survival. Patients with unoperated ToF rarely reach adulthood, and it is extremely rare to discover undiagnosed ToF in individuals over 60 years old. In this report, we describe an unusual case of a woman with unrepaired ToF who survived until the age of 71. She was fairly asymptomatic until the 7th decade of her life and complained only of dyspnea on exertion. The patient declined corrective cardiac surgery and preferred conservative management.

Aortic propagation velocity in predicting coronary artery disease: A systematic review and meta-analysis.

INTRODUCTION: Coronary artery disease (CAD) and its outcome, myocardial infarction, is yet a significant etiology of mortality and morbidity nowadays. The aortic propagation velocity (APV) can be a simple, straightforward and novel echocardiographic index for the risk stratification in the evaluation of CAD. In this meta-analysis, we evaluated the predictive role of APV in CAD. MATERIAL AND METHODS: Relevant electronic bibliographies (PubMed, ScienceDirect, Scopus, EMbase, the Cochrane library) were explored. Related reports were selected according to the inclusion and exclusion criteria. Meta-analysis was performed using the Comprehensive Meta-analysis 2.0 software. RESULTS: Eventually, 5 articles met the inclusion criteria and included in the meta-analysis. Five studies with 490 patients reported the APV mean in CAD and non-CAD groups. A random-effect model was used and the pooled findings demonstrated a significant higher APV in non-CAD group compared to CAD group (SMD: 2.39, 95% CI: 1.70-3.07, P < .001, I2: 84%, Q: 19.03). The diagnostic value of APV in predicting CAD showed 86.3% sensitivity (95% CI: 74-91, P value < .001, I2: 65%, Q: 8.53, P value: .03) and 83.8% specificity (95% CI: 69-94, P value < .001, I2: 60%, Q: 9.89, P value: .01). CONCLUSION: There was a predictive role of APV in CAD with suitable specificity and sensitivity. Moreover, aortic distensibility and aortic strain were significantly different in CAD and non-CAD patients. APV could be used as a good noninvasive tool for screening CAD.

Infective Endocarditis: Clinical Characteristics and Echocardiographic Findings.

Purpose: Infective endocarditis (IE) remains a disease with high morbidity and mortality. The aim of this study was to determine the clinical characteristics and echocardiographic features of patients with IE. Methods: We analyzed patients with either definitive or probable diagnosis of IE who were hospitalized in a teaching hospital in Mashhad, Iran between June 2011 and January 2020. Patients who survived were followed up by echocardiography for at least 6-month after hospital discharge. Results: A total of 82 cases with IE were included of which 62 (75.6%) received definitive diagnosis. The mean age was 39.7 ± 18.7 years and 52 (63.4%) were male. The most common preexisting structural cardiac abnormality that predispose patients to IE were congenital heart diseases (28 %) of which bicuspid aortic valve was more common (n = 12, 14.6%), followed by ventricular septal defect (n = 9, 11%) and Tetralogy of Fallot (TOF) (n = 2, 2.4%). Three (3.6 %) cases had rheumatic heart disease and 12 (14.6 %) were injecting drug users. The most common causative pathogen was Staphylococcus aureus, detected in 7 (19.4%) cases. Follow-up echocardiography revealed right or left ventricular failure in 10 (12.1%) cases. Cardiac complications occurred in 41 (50%) cases and systemic complications in 63 (76.8%). All-cause mortality was 41.5% (n = 34) and 6 (18.1%) patients died due to cardiovascular complications. Conclusions: The short- and long-term prognosis in IE was poor and the predictors for in-hospital and 1-year mortality were defined as heart failure and septic shock. Congenital heart disease and intravenous illicit drug using (IVDU) were the most common predisposing condition which may necessitate a revision in the IE prophylaxis recommendations.

Assessment of functional and structural echocardiography parameters in patients with frequent premature ventricular contractions without structural heart disease.

BACKGROUND: Premature ventricular contractions (PVCs) are early depolarizations of the myocardium which originate from the ventricle. PVCs have previously been considered a benign condition. The clinical significance of PVCs in patients without structural heart disease is controversial. METHODS: In this cross-sectional study, patients with a palpitation complaint who underwent electrocardiography (ECG) Holter recording for 48 hours were analyzed. Patients with frequent PVCs (more than ten times in 1 hour) were identified and enrolled in the study. 26 patients were in the PVC group, and 26 patients were in the control group without PVC. The identified patients underwent an echocardiographic examination with strain modality. RESULTS: There were 15 women (57.7%) in the PVC group and 17 women (65.4%) in the control group (P = 0.57). Two patients in the PVC group and three patients in the control group were hypertensive (P > 0.99). There was only one patient with diabetes in PVC and control group (P > 0.99). There were two smokers in the PVC group, whereas there was no smoker in the control group (P = 0.49). In comparison between two groups, patients with frequent PVCs had significantly larger left ventricular end-diastolic volume index (LVEDVI) (P = 0.048) along with lower left ventricular ejection fraction (LVEF) (P = 0.011), lower (more positive) left ventricular global longitudinal strain (LVGLS) (P = 0.001), and lower peak systolic mitral annular velocity (S') (P = 0.045). The left atrial volume index (LAVI) was significantly larger in the PVC group (P = 0.001). In speckle tracking echocardiography (STE) parameters, global peak atrial longitudinal strain (PALS) (P = 0.001) and peak atrial contraction strain (PACS) (P = 0.001) were significantly lower and time to peak longitudinal strain (TPLS) (P = 0.002) was significantly higher in the PVC group. CONCLUSION: In this study, left atrial (LA) and left ventricular (LV) function and geometry were adversely affected by frequent PVCs. Early diagnosis of these effects is possible with echocardiography along with strain analysis. It can guide the timely treatment of PVC to avoid the harmful effects of frequent PVCs on the heart.

Echocardiographic parameters in patients with and without hypotension during dialysis.

Introduction: Hypotension during dialysis is a common complication of hemodialysis and is associated with increased patient mortality and morbidity. Intradialytic hypotension is a decrease in systolic BP ≥20 mm Hg or a reduction in mean arterial pressure by 10 mm Hg along with clinical events and the need for correction. This study compares cardiac function, using transthoracic echocardiography with strain modality in patients with intradialytic hypotension with those without hypotension during dialysis. Methods: We studied 60 patients with chronic renal failure undergoing regular hemodialysis from April 2018 to February 2019. We compared thirty patients in the intradialytic hypotension group, with the remaining 30 patients in the control group. We did transthoracic echocardiography a day after hemodialysis using conventional, tissue doppler, and strain imaging. Results: Early diastolic mitral annulus velocity (e') was lower in the intradialytic hypotension group in comparison with the control group which their difference was statistically significant (5.540 ± 1.51 versus 6.920 ± 1.98, P value:0.007) Left Ventricular Ejection Fraction (LVEF) was also significantly lower in the intradialytic hypotension group (51.07 ± 8.714 versus 59.43 ± 4.133, P value < 0.001). Global Longitudinal Strain (GLS) was significantly lower in the intradialytic hypotension group (-14.17 ± 2.79 versus -18.99 ± 2.25, P value < 0.001). The receiver operator characteristics (ROC) curve point-coordinates that GLS of -16.85 and lower (more positive) has 83% sensitivity and 87% specificity for intradialytic hypotension. Conclusion: The echocardiographic assessment could be used as a tool for the prediction of hypotension during dialysis.

Prevalence of the presystolic wave in echocardiography and its association with the extent of coronary artery disease in patients with chronic stable angina.

INTRODUCTION: Since mortality and morbidity of coronary artery disease are high, there is a need for non-invasive diagnostic methods for early diagnosis and prediction of ischemic heart disease (IHD) outcome. This study aimed to assess the relationship between angiographic findings, the Presystolic wave (PSW) and some of the ischemic related parameters in echocardiography of the patients with chronic stable angina. MATERIALS AND METHODS: This cross-sectional study was conducted on the patients with chronic angina pectoris who referred to a tertiary hospital for coronary angiography in Mashhad, Iran. Demographic and medical history of the patients, as well as echocardiography findings, including ejection fraction (EF), regional wall motion abnormalities (RWMA), PSW and diastolic function were recorded. Angiographic findings, including SYNTAX score were also assessed. RESULTS: A total of 220 patients (132 males and 88 females) with the mean age of 62.43 ± 11.40 years old participated in this study. The prevalence of PSW was 49.1%. The absence of the PSW was related to more RWMA (P =.002), and higher stages of left ventricular diastolic dysfunction (LVDD) (P =.029) and higher SYNTAX score (P =.001). There was a significant association between the absence of the PSW and EF categories, especially in severe LV systolic dysfunction (LVEF < 30%) (P =.001). CONCLUSIONS: The findings of this study revealed that PSW is strongly associated with the SYNTAX score. The absence of the PSW may indicate patients at high-risk clinical status (higher SYNTAX score, severe systolic dysfunction, more RWMA, and higher stages of LVDD).

The Relationship between Left Ventricular Function Indices in Tissue Doppler Imaging and Exaggerated Blood Pressure Response During the Exercise Stress Test.

BACKGROUND: Studies have indicated that exaggerated hypertension during activity and stress can be a good predictor of the incidence of hypertension. This study tries to evaluate left ventricular (LV) function by tissue Doppler to assess early changes in ventricular compliance before the onset of Hypertension (HTN) in patients with exaggerated blood pressure response during the exercise test. MATERIALS AND METHODS: In this case-control study, 40 patients without a history of hypertension with systolic blood pressure less than 140/90 which referred for exercise test, were included. The exercise test was performed for all patients. Patients who had exaggerated blood pressure during the stress test were considered as cases and the controls with normal blood pressure responses. Then standard echocardiography and Tissue Doppler imaging performed and indices of LV systolic and diastolic were recorded. RESULTS: The LV mass in cases and controls were 174.9±50.78 and 152.9±33.59, respectively (P=0.114), and LV mass index in cases and controls were 127.4±13.5 and 79.8±15.75, respectively (P=0.023). Moreover, the LV Myocardial Performance Index were 0.68±0.11 and 0.48±0.06 in cases and controls, respectively (P<0.001). The heart rate, E/A, EE, E Velocity and S velocity were measuremented. Except E/A (P=0.009), there was no significant difference between the other variables measured between the cases and controls (P>0.05). CONCLUSION: The results of this study showed that using 2D conventional echocardiography as a noninvasive method if performed in prestigious centers can evaluate systolic and diastolic function Tissue Doppler parameters very well in the early stages of heart disease caused by HTN.

Cardiac Tamponade as a Very Rare Complication of Pseudoaneurysm of Mitral Aortic Intervalvular Fibrosa: A Case Report.

INTRODUCTION: The mitral-aortic intervalvular fibrosa (MAIVF) has a vital role in the integrity of the mitral and aortic valves. Pseudoaneurysm of the MAIVF (P-MAIVF) usually ensues as a complication of aortic valve surgery, and endocarditis can itself result in several catastrophic complications. CASE PRESENTATION: A 54-year-old male with acute dyspnea was admitted to our hospital. Upon physical and cardiac examination, low blood pressure, low O2 saturation, tachycardia, and a muffled heart were observed. Findings from the transthoracic echocardiography (TTE) were normal besides a massive pericardial effusion with clot formation in the pericardial space, and a pulsatile echo-free space at the posterior aspect of the aortic prosthesis. Accordingly, transesophageal echocardiography (TEE) was performed and confirmed the presence of a P-MAIVF that was rupturing into the pericardial space, causing cardiac tamponade. The patient presented with an unstable hemodynamic situation. A cardiac surgical operation was planned, however, cardiac arrest occurred at the time of induction. The operation was unsuccessful, and the patient expired in the operating room. CONCLUSIONS: Awareness of P-MAIVF formation after cardiac surgery, particularly after aortic valve replacement (AVR) due to an infected bicuspid aortic valve, is vital in order to prevent the occurrence of cardiac tamponade, a fatal event following this phenomenon. TEE is a modality of choice for identifying P-MAIVF in selected patients.

Prediction of the ischemic origin of functional mitral regurgitation in patients with systolic heart failure through posterior mitral leaflet angle.

BACKGROUND: Differentiating ischemic from non-ischemic functional mitral regurgitationý (FMR) in patients with cardiomyopathy is important in terms of the therapeutic decision-making and prognosis, but might be clinically challenging. In this study, the deformation of mitral valve (MV) indices in the prediction of the etiology of FMR was assessed using 2D transthoracic and tissue Doppler echocardiography. METHODS: This case-control study was conducted from April 2015 to January 2016 in Imam Reza Hospital in Mashhad, Iran. The participants consisted of 40 patients with ischemic cardiomyopathy (ICM) and 22 with non-ischemic dilated cardiomyopathy (DCM) who referred to the heart failure clinic. Transthoracic echocardiography was performed using the conventional 2D and tissue Doppler imaging (TDI). MV tenting area (TA), coaptation distance (CD), anterior and posterior mitral leaflet angles (AMLA and PMLA), and regional systolic myocardial velocity (Sm) were measured. RESULTS: There were no significant differences in echocardiographic indices between the two groups, besides Sm and PMLA which were significantly lower and higher, respectively, in ICM subjects in comparison with DCM patients (P = 0.002). PMLA ≥ 40 degrees and Sm ≤ 4 cm/second have a relatively high value for discriminating the ischemic from non-ischemic origin of functional MR in subjects with systolic heart failure (sensitivity: 80.0% and 70.0%, specificity: 73.0% and 77.3%; P = 0.001 and P < 0.001; respectively). Multivariable logistic regression identified PMLA and anterior Sm as major determinants for ischemic MR {Odds ratio (OR) [95% confidence interval (CI)] = 0.89 (0.82-0.96), P = 0.003, OR (95% CI) = 0.29 (0.14-0.60), P = 0.001, respectively}. CONCLUSION: The present study showed that PMLA and Sm had an independent significant association with the mechanism of FMR. These findings are suggestive of the predictive role of mitral deformation echocardiographic indices in the determination of the etiology of FMR in systolic heart failure.

The predictive role of aortic propagation velocity for coronary artery disease.

BACKGROUND: It is well recognized that cardio- vascular risk factors lead to histological and functional changes in aorta, and aortic stiffness is the best predictor of cardiovascular morbidity and mortality. In this study we evaluated the relation of a less evaluated echocardiographic parameter of aortic stiffness, aortic propagation velocity (APV) with the presence and severity of CAD. METHODS: This cross sectional study was conducted from May 2015 to March 2016 in Imam Reza hospital, Mashhad, Iran. Seventy patients who were referred for elective coronary artery angiography were enrolled. Patients were divided into two sub-groups based on angiographic findings: patients with CAD (38 patients, 54.3%) and non-CAD (32 patients, 45.7%). Transthoracic echocardiography was performed using the conventional 2D and color M-Mode imaging. Aortic propagation velocity (APV), aortic strain (AS) and distensibility (AD) were measured. The presence and Severity of CAD (assessing by syntax score) and their relation with aortic stiffness indices were assessed. RESULTS: Aortic strain (6.23 ± 1.93% versus 11.66 ± 4.86%, P < 0.0001), distensibility (2.46 ± 0.91 vs 5.57 ± 2.25 cm 2 dyn-110-3, P < 0.0001) and APV (48.63 ± 10.31 cm/sec vs 77.75 ± 9.97 cm/s, P < 0.0001) were significantly decreased in CAD group compared with non-CAD group. In our study, APV showed significant inverse relationship with CAD. Based on our results, APV less than 56 cm/sec could be used to predict CAD with sensitivity and specificity of 96.9 and 78.9% respectively. We also found an inverse correlation between APV and severity of CAD. CONCLUSION: Aortic strain, AD and APV (a less evaluated echocardiographic index) showed significant inverse correlation with presence and severity of CAD.

Mitral leaflet separation to evaluate the severity of mitral stenosis: Validation of the index by transesophageal three-dimensional echocardiography.

BACKGROUND: Determining severity of mitral stenosis (MS) by planimetry of mitral valve orifice area (MVA) has been a challenging issue in clinical practice, especially for less experienced cardiologists. Mitral leaflet separation (MLS) has shown a good correlation with MVA measurements. However, it has never been validated against multiplane 3DTEE planimetry (MVA3D ). We aimed to evaluate the accuracy of MLS index (MLSI2D ) in predicting MS severity. METHODS: We prospectively enrolled 144 patients with MS who underwent clinically indicated 2DTTE and 3DTEE. MLSI2D was yield by averaging the maximal leaflet tip distance in diastole, in parasternal long-axis and apical four-chamber views. MVA3D was used as the reference method. RESULTS: MLSI2D showed an excellent discriminatory ability between different grades of MS (P < .001). There was a significant positive correlation between MLSI2D and MVA3D (r = .93, P < .001) irrespective of concurrent mitral regurgitation (r = .94, P < .001) and/or atrial fibrillation (r = .92, P < .001). By receiver operating characteristic (ROC) curves, MLSI2D  ≤ 8.6 mm showed 100% sensitivity and 76% specificity for very severe MS. MLSI2D  ≥ 11.2 mm determined progressive MS with 100% sensitivity and 82% specificity. The study population was then divided into a derivation group and a validation group. A regression equation for MVA by MLSI2D was derived in first group. Then, the MVA was calculated by this equation in validation group and was not significantly different from MVA3D . CONCLUSION: MLSI2D showed an excellent ability to assess MS severity and correlates well with planimetered MVA measured by 3DTEE.

Time From the Beginning of the Right Ventricle Isovolumetric Contraction to the Peak of the S Wave: A New TDI Indicator for the Non-Invasive Estimation of Pulmonary Hypertension.

BACKGROUND: Echocardiography is a key screening tool in the diagnostic algorithm of pulmonary hypertension (PH). In addition, tissue doppler imaging (TDI) is a promising method for the noninvasive estimation of pulmonary artery pressure (PAP). OBJECTIVES: The aim of this study was to validate the accuracy of measuring the time from the beginning of the right ventricular isovolumetric contraction time (RV IVRT) to the peak of the S wave in the TDI of the base of the RV free wall (time to peak or TTP), as an indicator for the non-invasive estimation of pulmonary hypertension. PATIENTS AND METHODS: In this diagnostic test study, 60 consecutive patients referred for right heart catheterization (RHC) were enrolled. A pulse-wave TDI was performed before the cardiac catheterization, with a mean interval of 1 hour between the two measurements. The TDI variables, such as the RV IVRT, myocardial performance index (MPI), and the new "time to peak" parameter, were measured at the lateral basal RV free wall. The patients were divided into two sub-groups according to the RHC findings: no-PH (mean PAP < 25 mmHg) and PH (mean PAP ≥ 25 mmHg) groups. Then, we calculated the specificity and sensitivity of the TDI parameters (including the TTP) for the diagnosis of PH. RESULTS: In our study, the TTP showed a significant inverse relationship with the PAP. Based on our results, a TTP of less than 127 ms could be used to predict PH, with a sensitivity and specificity of about 70% (AUC = 0.746 ± 0.064). CONCLUSIONS: Based on the results of this study, we suggest the use of a novel "time from the beginning of isovolumetric contraction to the peak of the S wave" (TTP) parameter in the TDI of the base of the RV free wall to predict PH with acceptable accuracy in comparison with RHC.

Assosiation of Epicardial and Pericardial Fat Thickness with Coronary Artery Disease.

INTRODUCTION: Visceral adipose tissue is a known important risk factor for coronary artery disease (CAD). While some studies have suggested relationship between epicardial fat thickness (EFT) and CAD, there are no adequate studies for pericardial fat thickness (PFT). The aim of this study was to determine the association of EFT and PFT with CAD. METHODS: This cross-sectional study was conducted on patients who were candidates for elective coronary artery angiography, referred to Emam Reza Hospital, Mashhad, Iran during Jan 2014-2016. Demographic and laboratory data were collected. Transthoracic echocardiography was performed to determine average EFT and PFT at the standard parasternal long-axis view at end-systole for 3 cardiac cycles. SCA was performed on the same day. The patients were divided into two groups: CAD (n=59) and non-CAD (n=41) based on presence or absence of epicardial coronary artery stenosis of > 50%. Chi-square, independent T-test, and receiver operating characteristic (ROC) curve were used by SPSS Version 16 for data analysis. RESULTS: One hundred patients (44 women and 56 men) with an average age of 56.4 ± 9.9 years were studied. The two groups were not significantly different in demographic profile and cronary risk factors. While PFT was not significantly different between the two groups, EFT was significantly higher in CAD group (3.0 ± 3.69 vs. 1.2 ± 3.6, p <0.0001). Moreover, with the increase of the affected coronary arteries, EFT increased (p <0.0001). Gensini score had a strong correlation with amount of EFT (r = 0.765, p <0.0001). EFT with a cutoff value of 4.25 mm (sensitivity=79%, specificity=68%) was specified in predicting CAD. CONCLUSION: EFT measured by echocardiography can be used as an independent marker to predict CAD. More studies are needed to determine the predictive role of PFT for CAD.

Transcatheter Closure of Postinfarction Ventricular Septal Defect: A Case Report and Review of Literature.

Ventricular septal rupture (VSR) is an uncommon but serious complication of acute myocardial infarction (MI), associated with a high mortality rate. Although early surgical treatment improves the prognosis, hospital mortality after emergency surgery remains high. Transcatheter closure of postmyocardial infarction ventricular septal defect (PIVSD) has emerged as a potential strategy in selected cases. Current interventional reports are mainly restricted to PIVSD closure in the chronic and subacute setting, which only give a short term result. Herein, we report a case of acute post-MI VSR that was successfully closed using an Amplatzer postinfarction muscular ventricular septal defect (PIMVSD) occluder device with good immediate and long-term outcomes. The patient had undergone urgent coronary artery bypass surgery 3 days earlier in the setting of acute MI.

Unique echocardiographic markers of anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) in the adult.

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital heart defect in adults. We report a 38-year-old male presenting with exertional syncope. He was referred for the evaluation of multiple muscular ventricular septal defects diagnosed on an outpatient echocardiogram. Echocardiography revealed mild left ventricular enlargement, abnormal flow-pattern in the ventricular septum and dilatation of the right coronary artery. Pulsed-wave Doppler with sample volume placed in the coronary ostium showed systolic coronary flow predominancy. This unique finding is characteristic for ALCAPA and can differentiate it from other coronary anomalies. Coronary angiography confirmed ALCAPA syndrome. Surgical correction was planned.
