Project description:The differential diagnosis of true aneurysms and pseudoaneurysms is challenging, and multimodality cardiac imaging is often necessary. We report a case in which the limitations of these techniques are exposed, showing that post-operative evaluation of tissue layers remains the gold standard in establishing this diagnosis. (Level of Difficulty: Beginner.).
Project description:Acquired pseudoaneurysm of the left ventricle is a very rare disorder and mostly occurs after large transmural myocardial infarction (MI) with peak creatine phosphokinase-MB levels greater than 150 IU/mL. Patients developing left ventricular (LV) pseudoaneurysm usually present with angina or heart failure symptoms. Although different imaging modalities exist, coronary angiography is the gold standard for diagnosis. Surgery is the treatment of choice for LV pseudoaneurysms detected in the first months after MI. Here we report the case of a 74-year-old woman who presented with a relatively small inferior MI due to right coronary artery occlusion and complicated by LV pseudoaneurysm.
Project description:BackgroundPost-infarction perforation of the ventricular septum is recognized as a major complication of post-myocardial infarction. However, post-infarction ventricle dissection is seldom reported, as the ventricular shunt often accompanying this condition is a significant cause of cardiogenic shock. We encountered a rare case of ventricular dissection unaccompanied by a shunt, which caused a state of shock.Case presentationA 67-year-old man was diagnosed with acute myocardial infarction with a left ventricular oozing rupture. The occlusion of the left anterior descending artery was aspirated, followed by drainage of the pericardial bleeding and hemostasis of the left ventricle. After 15 h, he presented with sudden cardiogenic shock requiring extra-corporeal membrane oxygenation. The transesophageal echocardiogram showed a left ventricular septal aneurysm. Five days later, he underwent an operation, in which a ventricular septal wall dissection with a tear-forming large pseudoaneurysm was found. The tear was closed with a patch. He was weaned off extra-corporeal membrane oxygenation the next day. Αfter 4 months, he was discharged in a stable condition.ConclusionsRecognizing and identifying the cause of cardiogenic shock after myocardial infarction is crucial to provide the best treatment and surgical approach. Ventricular septal dissection should be considered, in addition to the usual complications, such as possible papillary muscle rupture, cardiac rupture, and perforation of the interventricular septum.
Project description:Postmyocardial infarction ventricular septal defect is an increasingly rare mechanical complication of acute myocardial infarction. We present a case of acute myocardial infarction from right coronary artery occlusion that developed hypotension and systolic murmur 12 hours after successful percutaneous coronary intervention. Although preoperative imaging suggested a large ventricular septal defect and a pseudoaneurysm, intraoperative findings concluded a serpiginous dissection of the ventricular septum. The imaging technicalities are discussed.
Project description:This study assessed the COVID-19 pandemic's impact on racial disparities in acute myocardial infarction (AMI) management and outcomes. We reviewed AMI patient management and outcomes in the pandemic's initial nine months, comparing COVID-19 and non-COVID-19 cases using 2020's National Inpatient Sample data. Our findings revealed that patients with concurrent AMI and COVID-19 had higher in-hospital mortality (aOR 3.19, 95% CI 2.63-3.88), increased mechanical ventilation (aOR 1.90, 95% CI 1.54-2.33), and higher initiation of hemodialysis (aOR 1.38, 95% CI 1.05-1.89) compared to those without COVID-19. Moreover, Black and Asian/Pacific Islander patients had higher in-hospital mortality than White patients, (aOR 2.13, 95% CI 1.35-3.59; aOR 3.41, 95% CI 1.5-8.37). Also, Black, Hispanic, and Asian/Pacific Islander patients showed higher odds of initiating hemodialysis (aOR 5.48, 95% CI 2.13-14.1; aOR 2.99, 95% CI 1.13-7.97; aOR 7.84, 95% CI 1.55-39.5), and were less likely to receive PCI for AMI (aOR 0.71, 95% CI 0.67-0.74; aOR 0.81, 95% CI 0.77-0.86; aOR 0.82, 95% CI 0.75-0.90). Black patients also showed less likelihood of undergoing CABG (aOR 0.55, 95% CI 0.49-0.61). Our study highlights elevated mortality and complications in COVID-19 AMI patients, emphasizing significant racial disparities. These findings underscore the pressing need for initiatives addressing healthcare disparities, enhancing access, and promoting culturally sensitive care to boost health equity.
Project description:BackgroundAlthough left ventricular aneurysm (LVA) is the most common mechanical complication of myocardial infarction (MI), it rarely involves the inferior or posterior left ventricular wall. Ventricular septal rupture (VSR) may be a fatal mechanical complication of MI but rarely occurs in the posterior or inferior portion of the interventricular septum. Thus, LVA and VSR as two mechanical complications of MI in the same patient are extremely rare.Case summaryA 65-year-old woman, who had inferior ST-segment elevation myocardial infarction 2 months before without reperfusion therapy, was admitted with exertional dyspnoea for 1 month. Echocardiography and computed tomography revealed true inferoposterior LVA and VSR as concurrent complications of MI. These imaging findings were confirmed during cardiac surgery. After successful coronary bypass grafting and ventriculoplasty, the patient recovered quickly and was discharged from the hospital.DiscussionA rare case of post-infarction inferoposterior LVA with concurrent interventricular septal rupture was reported. Transthoracic and transoesophageal echocardiography and cardiac computed tomography were valuable tools for the diagnosis of this rare condition. Combined coronary bypass grafting and ventriculoplasty were effective in treating this often fatal complication of inferior MI.
