Key result
Urgent transcatheter valve interventions in cardiogenic shock yield ~63% survival to hospital discharge.
Why the study?
Valvular cardiogenic shock is an under-recognized cause of hemodynamic collapse with high mortality and limited surgical options due to patient instability and comorbidities.
Case Report (n=8)
Transcatheter valve interventions supported by individualized mechanical circulatory support can achieve rapid hemodynamic stabilization in prohibitive-risk patients with valvular cardiogenic shock, particularly in left-sided obstructive lesions, though outcomes remain poor in postcardiotomy biventricular or advanced right ventricular failure.

Supports feasibility in prohibitive-risk valvular shock; hypothesis-generating and requires prospective validation before practice change.
Valvular cardiogenic shock is an under-recognized, yet potentially reversible cause of hemodynamic collapse associated with high mortality. Rapid recognition, comprehensive hemodynamic assessment, and multidisciplinary Heart Team management are critical for successful treatment. Surgical intervention is often prohibitive because of hemodynamic instability, advanced comorbidities, prior cardiac surgeries, or multiorgan dysfunction. We report a case series of patients with diverse valvular pathologies presenting with cardiogenic shock who were treated with transcatheter valve interventions, including transcatheter aortic valve replacement, transcatheter edge-to-edge repair, and balloon mitral valvuloplasty. Mechanical circulatory support was individualized according to shock phenotype and ventricular function. Although all procedures achieved technical success with immediate hemodynamic improvement, clinical outcomes varied according to the severity of underlying ventricular dysfunction, right ventricular failure, renal injury, and postcardiotomy physiology.

Aramouni et al. (2026) conducted a case report in Valvular cardiogenic shock (n=8). Transcatheter valve interventions (TAVR, valve-in-valve TAVR, transcatheter edge-to-edge repair, and balloon mitral valvuloplasty) with individualized mechanical circulatory support was evaluated on Technical procedural success, hemodynamic improvement, and survival to hospital discharge. Transcatheter valve interventions achieved technical success with immediate hemodynamic improvement in all 8 patients (100%) with valvular cardiogenic shock, with 5 of 8 (62.5%) surviving to discharge.
