Successful Urgent TAVI for Critical Aortic Valve Stenosis after ECMO Implantation

Medicina, 2022
Transcatheter aortic valve implantation (TAVI) has evolved to be the treatment of choice for patients with severe aortic stenosis and high perioperative risk. Cardiogenic shock is one of the most severe complications during the TAVI procedure, especially

Sotalol: A rescue drug in the face of life-threatening refractory ventricular tachycardia

Annals of Cardiac Anaesthesia, 2014
We describe postoperative refractory ventricular tachycardia (VT) in a patient following aortic and mitral valve replacement. Following an uneventful separation from cardiopulmonary bypass with dobutamine, the patient developed recurrent VT, 4 hours into

Cardiac cycle-synchronized electrical muscle stimulator for lower limb training with the potential to reduce the heart's pumping workload. [PDF]

PLoS ONE, 2017
The lower limb muscle may play an important role in decreasing the heart's pumping workload. Aging and inactivity cause atrophy and weakness of the muscle, leading to a loss of the heart-assisting role.

Aortic function in patients during intra-aortic balloon pumping determined by the pressure-diameter relation

, 1998
Objective: The physiologic basis for the hemodynamic and clinical improvement achieved by the use of intra-aortic balloon pumping in patients with cardiogenic shock has not been clarified in all its aspects. This study evaluated the possible contribution
