Rescue percutaneous transluminal septal myocardial ablation for difficult ventilator weaning in drug-resistant hypertrophic obstructive cardiomyopathy: a case report

This case highlights the role of PTSMA as a rescue therapy for patients with hypertrophic obstructive cardiomyopathy experiencing difficulty weaning from MV and haemodynamic instability. Further studies are warranted to evaluate the safety, efficacy, and long-term outcomes of PTSMA as an acute-phase intervention in critically ill patients with hypertrophic obstructive cardiomyopathy.
