A 33-year-old woman who had previously undergone mitral valve repair for native valve endocarditis presented with a submitral left ventricular pseudoaneurysm, with related mitral valve dysfunction. The operative approach to this complex pathophysiologic process is presented.

Ultrathin (≤ 70 μm strut thickness) strut DES have recently been shown to reduce target lesion failure (TLF) compared to thin-strut DES. Therefore, in order to assess the validity of improved outcomes associated with ultrathin-strut DES, we conducted an updated meta-analysis that includes recently published follow-ups of previously conducted randomized controlled trials (RCTs).

- Cardiogenic shock (CS) is a serious condition that can lead to severe complications, and this study looked at how changes in hemodynamic (blood flow-related) measurements correlate with patient outcomes in those suffering from heart failure or heart attack.
- Researchers analyzed data from over 2,200 patients to compare the hemodynamic profiles at the start and end of hospitalization, finding that mortality rates were higher in patients with acute myocardial infarction compared to those with heart failure.
- The study revealed that improvements in various hemodynamic and metabolic factors during hospitalization, such as lower blood pressure and better cardiac output, were linked to increased survival rates in both groups of patients.
Background: Studies assessing outcomes of transcatheter aortic valve replacement (TAVR) in patients with severe aortic valve stenosis (AS) with hemodynamic subtypes have demonstrated mixed results with respect to outcomes and periprocedural complications. This study aimed to assess the outcomes of TAVR in patients across various hemodynamic subtypes of severe AS.
Methods: PubMed, Embase, and Cochrane databases were searched through September 2023 to identify all observational studies comparing outcomes of TAVR in patients with paradoxical low flow low gradient (pLFLG), classic LFLG, and high gradient AS (HGAS).
Introduction: We aimed to pool randomized clinical trials (RCTs) comparing surgical aortic valve replacement (SAVR) with transcatheter aortic valve replacement (TAVR) and extrapolate pooled time-to-event data to compare long-term outcomes.
Methods: An electronic database search was performed for RCTs comparing SAVR with TAVR. The most current longest follow-up data for each RCT were included.
