Rapid complete reversal of systemic hypoperfusion after intra-aortic balloon pump counterpulsation and survival in cardiogenic shock complicating an acute myocardial infarction.

Background: In patients with cardiogenic shock (CS) complicating an acute myocardial infarction, a strategy of early revascularization (ERV) versus initial medical stabilization (IMS) improves survival. Intra-aortic balloon counterpulsation (IABC) provides hemodynamic support and facilitates coronary angiography and revascularization in CS patients.

Methods And Results: We evaluated 499 patients with record of systemic hypoperfusion status as an early response to IABC from the SHOCK trial (n = 185) and registry (n = 314) to determine the association between rapid complete reversal of systemic hypoperfusion (CRH) after 30 minutes of IABC and in-hospital, 30-day and 1-year mortality.

Mortality in patients with paravalvular abscess diagnosed by transesophageal echocardiography.

Background: Paravalvular abscess is a complication of endocarditis that may lead to persistent infection, conduction abnormalities, fistula formation, worsening congestive heart failure, and death.

Methods: Between 1991 and 2001, paravalvular abscess was identified on transesophageal echocardiography in 24 patients who subsequently underwent surgical treatment. Echocardiographic findings were reviewed for location of abscess, presence of a valvular prosthesis, valvular function, and presence of vegetations.

The risk of the development of aortic stenosis in patients with "benign" aortic valve thickening.

Background: Aortic valve thickening (AVT) without aortic stenosis (AS) is common and was often considered benign. However, it has recently been found to be associated with increased morbidity and mortality. It is unknown whether patients with AVT are at risk for the development of AS.
