Left Ventricular Free-Wall Rupture Case


67-year-old man presented to the emergency department 12 hours after the onset of chest discomfort. An electrocardiogram showed ST-segment elevation in the inferior leads (II, III, and aVF). The patient was immediately transferred to the cardiac catheterization laboratory, where he had a cardiac arrest with pulseless electrical activity. Emergency echocardiography revealed a large pericardial effusion; the effusion was drained by pericardiocentesis, which resulted in recovery of a spontaneous pulse, but the patient was hypotensive. In patients with a pericardial effusion after myocardial infarction, a mechanical complication such as rupture of the left ventricular free wall (a rare and catastrophic complication) is presumed. Since our institution does not have cardiac surgery available on site, the process of initiating transfer to the nearest cardiac-surgery center was begun immediately. However, before the patient could be transferred, coronary angiography showed three-vessel disease with subocclusion of the mid-right coronary artery. Left ventriculography confirmed a large left ventricular free-wall rupture with extravasation of blood and dye into the pericardial space .. During angiography, the patient’s condition became hemodynamically unstable, and pulseless electrical activity developed. Cardiopulmonary resuscitation was attempted but was unsuccessfu

Interferon-free therapy for hepatitis C ‘cured’ 90% of patients

Currently, doctors treating hepatitis C patients with cirrhosis (liver scarring) can only offer treatments that rely on the drug interferon, which unfortunately, only works for less than half of patients. Now, a new study found that an interferon-free combination of drugs was safe, well tolerated and cured over 90% of …

What is cirrhosis of the liver?

Cirrhosis of the liver describes a condition where scar tissue gradually replaces healthy liver cells. The main causes are sustained, excessive alcohol consumption, viral hepatitis B and C, and fatty liver disease – however, there are other possible causes. People with cirrhosis may develop jaundice (yellowing of the skin, eyes, …

Hepatitis A

Hepatitis A is a virus that causes infection and inflammation of the liver. It rarely results in serious liver damage or death and does not develop chronic liver disease. Unlike hepatitis B or C, it does not lead to chronic liver disease, but it can result in significant loss of income and …
