In patients with HCM, noninvasive assessment with TTDE revealed abnormal findings in the distal flow of the epicardial coronary arteries, very similar to those seen in the no-reflow phenomenon. These findings were independent of the type of hypertrophy and magnitude of the intraventricular pressure gradient in patients with obstructive HCM.

Cardiac involvement as an initial presentation of malignant lymphoma is a rare occurrence. We describe the case of a 26 year old man who had initially been diagnosed with myocardial infiltration on an echocardiogram, presenting with a testicular mass and unilateral peripheral facial paralysis. On admission, electrocardiograms (ECG) revealed negative T-waves in all leads and ST-segment elevation in the inferior leads. On two-dimensional echocardiography, there was infiltration of the pericardium with mild effusion, infiltrative thickening of the aortic walls, both atria and the interatrial septum and a mildly depressed systolic function of both ventricles. An axillary biopsy was performed and reported as a T-cell lymphoblastic lymphoma (T-LBL). Following the diagnosis and staging, chemotherapy was started. Twenty-two days after finishing the first cycle of chemotherapy, the ECG showed regression of T-wave changes in all leads and normalization of the ST-segment elevation in the inferior leads. A follow-up Two-dimensional echocardiography confirmed regression of the myocardial infiltration. This case report illustrates a lymphoma presenting with testicular mass, unilateral peripheral facial paralysis and myocardial involvement, and demonstrates that regression of infiltration can be achieved by intensive chemotherapy treatment. To our knowledge, there are no reported cases of T-LBL presenting as a testicular mass and unilateral peripheral facial paralysis, with complete regression of myocardial involvement.

Background: Some authors have pointed out that setting up an exam with random questions can impair student performance. Since the COVID-19 pandemic and compulsory social isolation, postgraduate medical education activities became virtual and exams were implemented online. Objective: The aim of the study was to analyse whether the random order of questions has any effect on test results. Method. Two exams were written: one on the Prevention of Cardiovascular Disease and another on Heart Valve Diseases. For each topic, two questionnaires were designed: a version with the questions in logical order and according to the estimated difficulty and another with the same questions randomly distributed. Each exam had 50 multiple-choice questions with 3 options, and the maximum possible score was 50 The exams were taken on the Moodle platform, with synchronous modality, and the time available was 75 minutes. The results were expressed as scores obtained (range and central tendency) and according to the index of difficulty of the questions. Results. The number of respondents was 284 residents, students of the Biannual Cardiology Course: two 1st year groups (Prevention topic) and two 2nd year groups (Valve diseases). There was no difference between the results of the two versions of the same exam. Conclusions. This study lacks sufficient power to support either way of question order in clinical sciences exams, giving rise to new queries.
