AbstractAbstract PDF
Persistent hypoxemia following myocardial infarction can be challenging to manage and often requires considering uncommon etiologies such as extracardiac shunts. This case report describes a 78-year-old man with persistent hypoxemia post-myocardial infarction, which was ultimately attributed to a large pulmonary arteriovenous malformation (AVM). The patient presented with cardiogenic shock and underwent successful revascularization. Despite clinical improvement, the hypoxemia persisted, prompting further evaluation. Bedside saline contrast echocardiography and computed tomography confirmed the presence of a large pulmonary AVM, explaining the uncorrectable hypoxemia. This case underscores the importance of considering extracardiac shunts in patients with refractory hypoxemia and illustrates the utility of bedside imaging in such situations.

AbstractAbstract PDF
Background
Complete revascularization has demonstrated better outcomes in patients with acute myocardial infarction (AMI) and multivessel disease. However, in the case of left main (LM) culprit lesion AMI with multivessel disease, there is limited evidence to suggest that complete revascularization is better.
Methods
We reviewed 16,831 patients in the Korea Acute Myocardial Infarction Registry who were treated from July 2016 to June 2020, and 399 patients were enrolled with LM culprit lesion AMI treated with percutaneous coronary intervention. We categorized the patients as those treated with complete revascularization (n=295) or incomplete revascularization (n=104). The study endpoint was major adverse cardiac and cerebrovascular events (MACCE), a composite of all-cause death, myocardial infarction, ischemia-driven revascularization, stent thrombosis, and stroke. We performed propensity score matching (PSM) and analyzed the incidence of MACCE at 1 year.
Results
After PSM, the two groups were well balanced. There was no significant difference between the two groups in MACCE at 1 year (12.1% vs. 15.2%; hazard ratio, 1.28; 95% confidence interval, 0.60–2.74; p=0.524) after PSM. The components of MACCE and major bleeding were also not significantly different.
Conclusion
There was no significant difference in clinical outcomes between the groups treated with complete or incomplete revascularization for LM culprit lesion AMI with multivessel disease.

AbstractAbstract PDF
Purulent pericarditis is defined as a localized pericardial infection with gross pus formation in the pericardial space. Although purulent pericarditis is now rare in the antibiotic era, it may be life-threatening. We describe a rare case of purulent pericarditis that originated from a subdiaphragmatic suppurative focus in an immunocompromised host.
