“…Non-ischaemic causes of sudden-onset dyspnoea such as pulmonary embolism, cardiac tamponade, pneumothorax, acute pulmonary oedema, airway obstruction and pneumonia with atelectasis, were then excluded by physical examination and angio-CT. However, in a patient in shock, with cardiovascular risk factors, previous cardiovascular events and basal ST–T changes, it is necessary to exclude coronary artery disease, and echocardiography may be crucial 7. In fact, transthoracic Doppler echocardiography has a vital role in the diagnosis of isolated RV infarction, assessment of LV ischaemia and exclusion of other diagnoses 8.…”

A 73-year-old woman was admitted to the emergency room due to sudden-onset dyspnoea, altered mental status and haemodynamic instability. ECG showed a junctional rhythm, T-wave inversion in I, aVL and V2-V6 (present in a previous ECG), and no ST/T changes in the right precordial leads. Transthoracic echocardiography, however, revealed a severe depression of global systolic function of right ventricle with akinesia of free wall and a normal left ventricular function. Coronary angiography showed an occlusion of the proximal segment of the right coronary artery, which was treated with balloon angioplasty, and a chronic lesion of the anterior descending artery. The patient had a good recovery and was discharged on the 14th day. Myocardial perfusion scintigraphy (stress and rest) was performed a month later, showing a fixed perfusion defect in the apex and anterior wall (medium-apical), with no signs of ischaemia.

“…Echocardiography is also useful as a modality to rule out pericardial tamponade, which is the major differential diagnosis in the setting of right ventricular infarction. Classically right ventricular dilatation, abnormal right ventricular wall motion, paradoxical motion of the interventricular septum and tricuspid regurgitation are echocardiographic features of RVMI (13,14). Echocardiography has 82% sensitivity and 93% specificity in detecting RVMI when right ventricular scintigraphy is used as the comparative standard (14).…”

ÖZETAmaç: Sağ koroner arter (SKA) ile ilişkili akut inferiyor miyokardial enfarktüslü (İME) olgularda sağ ventrikül (SV) tutuluşunun saptanması için trombolitik tedavi öncesi ve sonrası triküspit annülüsün hareketi ve hızı araştırılmıştır. Yöntemler: İlk SKA ile ilişkili akut İME'lü olgular bu pilot prospektif kohort çalışmasına alındı. Triküspit annülüs hareketi (TAPSE, tricuspid annular plane systolic excursion) ile, annüler hızlar ise ekokardiyografik doku Doppler'i ile ölçüldü. Veriler trombolitik tedaviden ve koroner anjiyografiden önce ve sonra kaydedildi. Sağ ventrikül miyokart enfarktüsü (SVME) elektrokardiyografik ve anjiyografik kriterlerin müşterek varlığı şeklinde tanımlandı. İstatistiksel analizde Ki-kare ve Student's t-testi kullanıldı. Bulgular: Toplam 31 olgu çalışmaya alındı. Trombolitik tedavi öncesi annüler hızlar ve TAPSE, SVME'ü olmayan olgularda SVME olan olgulardan anlamlı derecede fazlaydı. Triküspit hızlarının ve hareketlerin trombolitik tedavi öncesi ve sonrası karşılaştırılması SVME olmayan olgularda anlamlı bir farklılık göstermedi (TAPSE ve sistolik triküspit hızı (Sa) için sırası ile 21.6±2.1 mm vs. 21.8±2.0 mm p>0.05 ve 136.0±8.8 mm/s vs. 137.5±9.0 mm/s, p>0.05). Tersine, SVME'ü olan olgularda TAPSE ve Sa trombolizis sonrası, trombolitik tedavi öncesine göre anlamlı derecede arttı (TAPSE ve Sa için sırası ile 16.2±2.0 mm vs. 17.6±1.8 mm p=0.001 ve 110.0±12.6 mm/s vs. 113.08±12.7 mm/s p=0.027). ABSTRACTObjective: Tricuspid annular movement and velocities before and after thrombolytic therapy were investigated for the detection of right ventricular (RV) involvement in RCA (right coronary artery)-related acute inferior myocardial infarction (IMI). Methods: Patients with RCA-related acute IMI were evaluated for this pilot prospective cohort study. Annular movement was measured by TAPSE (tricuspid annular plane systolic excursion), and annular velocities were measured by tissue Doppler echocardiography. Data collected before and after thrombolysis and angiography. Diagnosis of RV myocardial infarction (RVMI) was defined by co-presence of electrocardiographic and angiographic criteria. Chi-square and Student's t-tests were used in statistical analysis. Results: Thirty-one patients were included. Before thrombolysis, annular velocities and TAPSE were found significantly higher in patients without RVMI than in patients with RVMI. Comparison of tricuspid systolic velocity (Sa) and movement before and after thrombolytic therapy in patients without RVMI revealed no significant difference (21.6±2.1 mm vs. 21.8±2.0 mm p>0.05 and 136.1±8.8 mm/s vs. 137.5±9.0 mm/s p>0.05, for TAPSE and Sa respectively). Contrarily, in patients with RVMI, TAPSE and systolic velocity increased significantly after thrombolysis compared with pre-thrombolysis (16.2±2.0 mm vs. 17.6±1.8 mm p=0.001 and 110.0±12.6 mm/s vs. 113.08±12.7 mm/s p=0.027 for TAPSE and Sa respectively). Diastolic velocities did not change significantly after thrombolysis in patients with RVMI. Conclusion: Tricuspid annular movement and velocity m...

“…The increasing experience with echocardiography [echo] in recent decades has greatly facilitated the diagnosis of acute myocardial infarction [AMI], as echo is an inexpensive, readily available, ambulatory, non-invasive method [24]. Echo is useful, not only in the diagnosis of AMI but also in prognosis, the monitoring of complications and in follow-up.…”

Myocardial Infarction

View full text Add to dashboard Cite

Myocardial infarction (MI) is a clinical condition that develops associated with a sudden reduction or interruption of the blood flow of the vessels supplying the heart for various reasons. The electrocardiographic, echocardiographic and enzymatic diagnostic criteria of MI have been well defined in adults, in children there are some difficulties. Although seen more often in the presence of congenital heart disease (CHD), MI may also be seen in patients without CHD. Unlike atherosclerotic coronary artery disease in adult patients, ischaemia and infarct in children are often associated with coronary artery anomalies and CHD. In addition, congenital prothrombotic diseases, vasculitis, surgical or interventional procedures may also cause ischaemia and infarct. Subendocardial ischaemia, especially aortic stenosis characterised by hypertrophy in the left ventricle is often seen in hypertrophic cardiomyopathy or hypertensive patients. The most important risk factors in neonates and infants are the presence of CHD, coronary artery anomalies and perinatal asfixia. The most frequently seen causes of pediatric myocardial infarction (PMI) are abnormal left coronary artery originating from the pulmonary artery (ALCAPA) and Kawasaki disease. Another often seen cause of PMI is patients who underwent arterial switch operations.
