Early Utilization of Mechanical Circulatory Support in Acute Myocardial Infarction Complicated by Cardiogenic Shock: The National Cardiogenic Shock Initiative.

Background: Acute myocardial infarction complicated by cardiogenic shock (AMI-CS) is associated with significant morbidity and mortality. Mechanical circulatory support (MCS) devices increase systemic blood pressure and end organ perfusion while reducing cardiac filling pressures.

Methods And Results: The National Cardiogenic Shock Initiative (NCT03677180) is a single-arm, multicenter study.

Sustained Mechanical Aspiration Thrombectomy for High Thrombus Burden Coronary Vessel Occlusion: The Multicenter CHEETAH Study.

Background: Poor myocardial reperfusion due to distal embolization and microvascular obstruction after percutaneous coronary intervention is associated with increased risk of morbidity and mortality. Prior trials have not shown a clear benefit of routine manual aspiration thrombectomy. Sustained mechanical aspiration may mitigate this risk and improve outcomes.

Initial experience with a continuous mechanical aspiration system for thrombus removal before percutaneous coronary intervention.

Objectives: Here we investigate the safety and efficacy of a continuous mechanical aspiration system when used before percutaneous coronary intervention (PCI) in patients with acute coronary syndrome (ACS).

Background: Historically, trials of routine manual aspiration thrombectomy in ACS patients have reported mixed results. This may be due to the technical limitations of manual aspiration, which suffers from decreasing vacuum power as aspiration is performed.

The dilated coronary sinus: utility of coronary sinus cross-sectional area and eccentricity index in differentiating right atrial pressure overload from persistent left superior vena cava.

Background: Pulmonary hypertension and right atrial pressure overload (RAPO) cause dilation of the coronary sinus (CS). Persistent connection of the left superior vena cava (LSVC) to the CS is another cause of CS dilation. The purpose of this study was to evaluate the usefulness of coronary sinus cross-sectional area (CSA) and eccentricity index (EI) in differentiating persistent LSVC from right heart overload and RAPO in patients with dilated CS.

Echocardiographic assessment of the accuracy of computed tomography in the diagnosis of hemodynamically significant pericardial effusions.

Background: Although Doppler echocardiography is the noninvasive test of choice for the diagnosis of hemodynamically significant pericardial effusion (HSPE), pericardial effusion is often first detected by computed tomography (CT). Few data are available, however, regarding the accuracy of CT in the diagnosis of cardiac tamponade.

Methods: We retrospectively identified 28 consecutive hospitalized patients with pericardial effusion who underwent both chest CT and echocardiography within 48 hours between 2001 and 2005.
