Aims: Cardiogenic shock remains a significant cause of mortality despite multiple advancements in medical interventions. Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) provides crucial circulatory support but also increases left ventricular (LV) after-load, potentially worsening outcomes. Effective LV unloading strategies can enhance patient survival during VA-ECMO treatment.

Background: Differences between female and male patients may influence the outcomes of transcatheter aortic valve replacement (TAVR). However, knowledge regarding known sex differences in TAVR procedures among Chinese people remains limited. Therefore, this study aimed to investigate the impact of sex-related differences on reverse left ventricular (LV) remodeling following TAVR in the Chinese population.

Volumetric modulated arc therapy (VMAT) for lung cancer involves complex multileaf collimator (MLC) motion, which increases sensitivity to interplay effects with tumour motion. Current dynamic conformal arc methods address this issue but may limit the achievable dose distribution optimisation compared with standard VMAT. This study examined the clinical utility of a VMAT technique with monitor unit limits (VMATliMU) to mimic conformal arc delivery and reduce interplay effects while maintaining plan quality.

Aims: Non-pharmacological therapies for acute decompensated heart failure (HF) and cardiogenic shock have evolved considerably in recent decades. Short-term mechanical circulatory support (MCS) devices can be used as circulatory backup. While nearly all available devices use continuous flow, evidence indicates that pulsatile flow can be more effective.
