The patient was intubated, and urgent coronary angiography revealed severe tandem stenosis from the proximal to mid-left anterior descending coronary artery. We performed a primary percutaneous coronary intervention (PCI) and deployed drug-eluting stents from the left main trunk to mid-left anterior descending coronary artery. Although the procedure was successful, the patient went into cardiogenic shock a few hours later. Transthoracic echocardiography revealed low cardiac function and severe aortic stenosis. We decided to perform transcatheter aortic valve implantation using a self-expandable valve, followed by the insertion of a left ventricular assist device. The combination of procedures achieved haemodynamic stability.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>It is difficult to treat cardiogenic shock that develops in patients with severe aortic stenosis and ST-elevation myocardial infarction. This case report demonstrates that combined transcatheter aortic valve replacement using a self-expanding valve and left ventricular assist device placement can be safe and effective after a primary
