Obstructive mechanical mitral valve thrombosis and gastric adenocarcinoma: A therapeutic dilemma

Fibrinolysis is an option for the management of mechanical prosthetic valve thrombosis when surgery has prohibitive risks. Current guidelines suggest recombinant tissue plasminogen activator (not to exceed 100 mg) with unfractionated heparin. A low-dose (25 mg) alteplase regimen as treatment in patients with a high risk of bleeding warrants further research. This report describes the case of a 65-year-old woman with a history of mechanical prosthetic mitral valve replacement who was diagnosed with signet ring cell adenocarcinoma of the stomach and obstructive mechanical prosthetic thrombosis on echocardiogram. Details of challenging aspects of this case and the use of modified fibrinolytic therapy are provided

THE DIAGNOSTIC PERFORMANCE OF CORONARY COMPUTED TOMOGRAPHIC ANGIOGRAPHY COMPARED WITH INVASIVE CORONARY ANGIOGRAPHY IN SYMPTOMATIC PATIENTS LONG-TERM PROGNOSTIC IMPLICATIONS

Objective: We aimed to investigate the diagnostic accuracy of 64-multidetector coronary computed tomographic angiogra-phy (CCTA) for stable symptomatic patients and evaluate the relationship between severity of coronary artery disease (CAD), cardiovascular risk scores, and coronary artery calcium (CAC) scores. We also assessed the possible predictors of all-cause mortality at a median of 10 years of follow-up

The relation of echo-derived lateral MAPSE to left heart functions and biochemical markers in patients with preserved ejection fraction: Short-term prognostic implications

Objective Mitral annular plane systolic excursion (MAPSE) is a simple way to evaluate-left ventricle (LV) function. Our aim was to explain the relationship of MAPSE with LV function and biochemical markers in patients with preserved ejection fraction (EF), and to determine whether it has an effect on prognosis in echocardiography (echo) practice. Methods Consecutive patients referred to the echo laboratory between November 2020 and March 2021 were included in the study. In addition to conventional parameters, MAPSE of the lateral mitral annulus was measured in all patients. Patients were divided into three groups according to lateral MAPSE: low (= 15 mm). Results A total of 512 patients with preserved EF were included in the study. MAPSE was low in 44 patients (9%), relatively preserved in 231 patients (45%), and high in 237 patients (46%). The mean age was higher in the low group compared to the other two groups (p < 0.001) and the body mass index was increased in the low group compared to the high group (p = 0.010). Atrial fibrillation and hypertension were more common in patients with low MAPSE. The rate of diastolic dysfunction (DD) and all-cause hospitalization were higher in the low and relatively preserved groups than in the high group (p < 0.001, p = 0.002; respectively). The pro-BNP level and mortality rate were higher in the low group compared to the relatively preserved and high groups (p = 0.007, p = 0.005; respectively). MAPSE was identified as independent predictor of hospitalization (OR: 0.284, 95% CI: 0.093-0.862, p = 0.026) via multivariate analysis and independent predictor of in-hospital mortality (HR: 0.002, 95% CI: 0-0.207, p = 0.008). Conclusions Analysis of LV longitudinal function by echo-derived lateral MAPSE when LV ejection fraction is normal provides important information about DD and related heart failure and may predict prognosis in echo practice

Can high-sensitive troponin levels within the normal range predict positivity in treadmill test?

Background This study aimed to determine whether a high level of high-sensitivity troponin T (hsTnT) predicts a positive treadmill test in patients with suspected stable ischemic heart disease (SIHD). Methods In all, 366 patients with suspected SIHD were included in the study. We measured the serum hsTnT levels before the treadmill test. The treadmill test was performed according to the Bruce protocol. Results Of the 366 patients, 97 had positive treadmill tests. The hsTnT levels were significantly higher in the positive group than in the negative group. In the binary logistic regression analysis, hsTnT, pretest probability, metabolic equivalents (METs), target heart rate (THR) percentage, and Duke treadmill score (DTS) were independent predictors of a positive treadmill test [hsTnT odds ratio (OR): 2.178, P < 0.001; pretest probability OR: 1.036, P = 0.007; METs OR: 0.755, P = 0.008; THR OR: 0.773, P < 0.001; DTS OR: 2.661, P = 0.012]. In the receiver operating characteristic (ROC) curve analysis, the area under the curve (AUC) value of the model with the combined parameters of hsTnT, pretest probability, METs, THR, and DTS was statistically significant in predicting a positive treadmill test [combined model AUC: 0.945 (0.922-0.968), P < 0.001]. Conclusions In sum, high pretest hsTnT levels predicted a positive treadmill test in patients with suspected SIHD. Analysis of the hsTnT levels before the treadmill test can increase the sensitivity and specificity of the treadmill test. The methods for measuring hsTnT levels are cheap and easily accessible and can be used before the treadmill test in patients with suspected SIHD

Role of global longitudinal strain in discriminating variant forms of left ventricular hypertrophy and predicting mortality.

Wide QRS Complex and Lateral ST-T Segment Abnormality Are Associated With Worse Clinical Outcomes in COVID-19 Patients

Background: The information on electrocardiographic features of patients with coronavirus disease 2019 (COVID-19) is limited. Our aim was to determine if baseline electrocardiographic features of hospitalized COVID-19 patients are associated with markers of myocardial injury and clinical outcomes
