Left ventricular free wall rupture as a result of delayed presentation of an inferior ST-elevation myocardial infarction due to fear of COVID-19: case report.

BACKGROUND: Left ventricular free wall rupture (LVFWR) is a rare complication after myocardial infarction and usually occurs 1 to 4 days after the infarct. Over the past decade, the overall incidence of LVFWR has decreased given the advancements in reperfusion therapies. However, during the COVID-19 pandemic, there has been a significant delay in hospital presentation of patients suffering myocardial infarctions, leading to a higher incidence of mechanical complications from myocardial infarctions such as LVFWR. CASE PRESENTATION: We present a case in which a patient suffered a LVFWR as a mechanical complication from myocardial infarction due to delay in seeking care over fear of contracting COVID-19 from the medical setting. The patient had been having chest pain for a few days but refused to seek medical care due to fear of contracting COVID-19 from within the medical setting. He eventually suffered a cardiac arrest at home from a massive inferior myocardial infarction and found to be in cardiac tamponade from a left ventricular perforation. He was emergently taken to the operating room to attempt to repair the rupture but he ultimately expired on the operating table. CONCLUSIONS: The occurrence of LVFWR has been on a more significant rise over the course of the COVID-19 pandemic as patients delay seeking care over fear of contracting COVID-19 from within the medical setting. Clinicians should consider mechanical complications of MI when patients present as an out-of-hospital cardiac arrest, particularly during the COVID-19 pandemic, as delay in seeking care is often the exacerbating factor.

Inferior ST-elevation myocardial infarction managed with a pharmacoinvasive strategy and conservative management of delayed atrioventricular block: classical case report.

BACKGROUND: The 2017 ESC guideline on patients with ST-segment elevation myocardial infarction (STEMI) provides guidance regarding the optimal management of these patients. Transient atrioventricular (AV) block is a relatively common complication of inferior STEMI and its management is also addressed in the guidelines. CASE SUMMARY: A 64-year-old gentleman with multiple cardiovascular risk factors presented to the emergency department with a history of ischaemic type chest pain and evidence of inferior ST-segment elevation on his electrocardiogram (ECG). First-degree AV block was noted on his initial ECG. He was given thrombolytic therapy as part of a pharmacoinvasive strategy of reperfusion. He, however, failed fibrinolytic therapy, and emergency angiography revealed critical disease of the right coronary artery which was successfully stented. Subsequent to reperfusion, he developed complete AV block without evidence of re-infarction, which was managed conservatively with successful resolution of the block after 7 days of expectant management with temporary transvenous pacing. DISCUSSION: We highlight some of the important management principles from the ESC guideline of STEMI including timing and the management of AV block in these patients. In addition, we highlight the role of a pharmacoinvasive strategy for reperfusion where timeous primary percutaneous coronary intervention cannot be performed. The usefulness of such a strategy within the COVID-19 era is also emphasized.
