Article Synopsis
  • Differentiating tachycardia-induced cardiomyopathy (TIC) from dilated cardiomyopathy (DCM) is difficult for patients with heart failure (HF) and left ventricular dysfunction caused by supraventricular tachyarrhythmia (SVT).
  • A study analyzed 43 patients admitted for HF due to SVT; those whose left ventricular ejection fraction (LVEF) improved were classified as TIC, while those with persistent low LVEF were classified as DCM.
  • Key findings showed that diabetes, late gadolinium enhancement (LGE), low left ventricular peak systolic velocity, and specific right ventricular displacement measurements could help predict LVEF recovery and distinguish between TIC

Background: Cardiac computed tomography angiography (CCTA) is precise in noninvasive coronary atherosclerosis characterization but its value in the diagnosis of intracoronary thrombus remains unknown. Therefore, our aim was to evaluate CCTA for intracoronary thrombus and stenosis detection in patients with acute coronary syndromes with high thrombus burden selected for a deferred stenting strategy.

Methods: We systematically performed a CCTA in consecutive patients following a deferred stenting strategy, 24 h before the scheduled repeated coronary angiography including optical coherence tomography (OCT) imaging.

In patients admitted for heart failure (HF) with reduced left ventricular ejection fraction (LVEF) and a concomitant supraventricular tachyarrhythmia (SVT) it is a challenge to predict LVEF recovery and differentiate tachycardia-induced cardiomyopathy (TIC) from dilated cardiomyopathy (DCM). The role of the electrocardiogram (ECG) and cardiac magnetic resonance (CMR) and in this acute setting remains unsettled. Forty-three consecutive patients admitted for HF due to SVT and LVEF < 50% undergoing CMR in the acute phase, were retrospectively included.

Article Synopsis
  • Some COVID-19 patients with pneumonia experience a cytokine storm that worsens their condition, potentially benefiting from anti-inflammatory treatments like colchicine.
  • A trial involving 240 hospitalized patients tested the effectiveness of colchicine compared to standard care in reducing serious outcomes (like mechanical ventilation and death).
  • The results showed no significant difference in outcomes between those treated with colchicine and the control group, indicating that colchicine did not offer any additional clinical benefits.

Hypertrophic cardiomyopathy (HC) is the most common cardiovascular inherited disease, and it is associated with arrhythmic events, heart failure, and death. Strain analysis by tissue tracking (TT) techniques on cardiac magnetic resonance (CMR) is a novel noninvasive diagnostic tool. However, the usefulness of CMR-TT to identify patients with HC at risk of adverse outcomes remains unknown.

Background: CHADS-VASc score (congestive heart failure; hypertension; ages ≥ 74 years (2 points); diabetes; stroke, transient ischemic attack, or systemic embolism (2 points); vascular disease; ages 65 - 74 years; sex (female)) is a widely used clinical scale to estimate the risk of stroke in patients with non-valvular atrial fibrillation (AF). However, the relationship between the increase in CHADS-VASc score and atrial remodeling remains unsettled.

Methods: Twenty-five consecutive patients undergoing cardiac computed tomography (CT) were recruited.

Whether sex differences exist in cardiac magnetic resonance (CMR) findings in patients with hypertrophic cardiomyopathy (HCM) remain unknown. We sought to assess and compare CMR characteristics in male and female patients with HCM. From January-2006 to October-2017, 165 consecutive HCM patients evaluated with CMR were included.

Recently a novel pattern of helical distribution of hypertrophy has been described in patients with hypertrophic cardiomyopathy (HCM). Our aim was to determine its prevalence and potential implications in an unselected cohort. One-hundred- and eight consecutive patients diagnosed with HCM by cardiac magnetic resonance (CMR) were included (median clinical follow up of 1718 days).

We report the case of a pulsatile mass found in a patient who presented for a routine echocardiogram. The mass turned out to be an exceedingly rare mitral-subannular pseudoaneurysm involving the membranous atrioventricular septum with systolic expansion protruding into right atrium, discovered late after repeated multiple valve replacement surgery. Although these pseudoaneurysms may present asymptomatically, surgical intervention might be indicated because of the risk of rupture.

Myocardial infarction and sudden cardiac death are frequently the first manifestation of coronary artery disease. For this reason, screening of asymptomatic coronary atherosclerosis has become an attractive field of research in cardiovascular medicine. Necropsy studies have described histopathological changes associated with the development of acute coronary events.

Early gadolinium enhancement (EGE), one CMR diagnostic criteria in acute myocarditis, has been related with hyperemia and capillary leakage. The value of EGE in hypertrophic cardiomyopathy (HCM) remains unknown. Our aim was to determine the prevalence of EGE in patients with HCM, and its relation with late gadolinium enhancement (LGE).

Lipomas are well-differentiated, encapsulated masses composed of adipocytes. Intrathoracic lipomas are rare, but found most commonly in the pleura or anterior mediastinum. Computed tomography shows fatty, homogenous content of the mass and will establish the diagnosis.

Background: Helical computed tomography has been introduced for the diagnosis of pulmonary embolism.

Objective: To determine the clinical safety of withholding anticoagulant treatment in patients with suspicion of pulmonary embolism and negative helical computed tomography study.

Methods: During a 9-month period, we performed a prospective study including 209 consecutive patients who underwent helical computed tomography for clinical suspicion of pulmonary embolism.
