Cardiogenic shock due to dynamic left ventricular outflow tract obstruction in acute myocardial infarction

Manifestation of latent left ventricular outflow tract obstruction caused by acute myocardial infarction: An important complication of acute myocardial infarction

“…Twenty cases of transient LVOT obstruction with AMI have been reported to date [1][2][3][4][5][6][7][8][9][10] ( Table 1). Seven of these 20 patients (35%) had 1-VD of LAD.…”

“…Therefore, the maintenance of blood flow through the major SB would be indispensable to cause LVOT obstruction in AMI. Unfortunately, there are few reports describing the major SB in these reports [1][2][3][4][5][6][7][8]10].…”

“…

IntroductionDynamic left ventricular outflow tract (LVOT) obstruction is a rare complication in acute myocardial infarction (AMI), and about 20 cases have been reported to date [1][2][3][4][5][6][7][8][9][10]. While LVOT obstruction is a potentially reversible complication of AMI, some patients with transient LVOT obstruction during AMI have experienced myocardial rupture and died [3,6].

Pharmacological Treatment of Acute Heart Failure: Current Treatment and New Targets

“…Furthermore, the guidelines recommend consideration of right‐heart catheterization and the initiation of mechanical support. Patients with persistently low blood pressure should be scrutinized for underlying reversible causes (e.g., pulmonary embolism, acute mechanical problems, and severe valvular disease) 4 , 5 In hypoxemic patients (SpO 2 <90%) without contraindications who are not responding to oxygen therapy, noninvasive ventilation might be necessary.…”
