Colchicine is one of the established drugs of choice for post-myocardial infarction (MI) induced pericarditis, given its anti-inflammatory properties. Recently, colchicine received FDA approval for secondary prevention of atherosclerotic cardiovascular disease, which leads to concerns regarding its anti-healing effects on myocardial tissue post-infarction. We present a case of a suspected colchicine-induced myocardial rupture in an elderly male, who presented with a syncopal episode while on colchicine three weeks after the late presentation of infero-posterior ST-elevation myocardial infarction.

Primary cardiac lymphomas (PCLs) are a rare clinical entity, in which treatment guidelines remain to be established. Rituximab, etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin (R-EPOCH) has been proposed, given that it involves a continuous infusion of anthracycline, reducing the risk of a cardiotoxicity and therefore the theoretical risk of perforation. However, the literature on this method of treatment is scarce. Herein, we present a unique case of a 75-year-old male, diagnosed with primary cardiac diffuse large B-cell lymphoma (DLBCL) with relatively unusual involvement of the coronary sinus, treated first with one cycle of R-EPOCH, followed by three cycles of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) to reduce said risk. To our knowledge, this is one of two cases, in which a patient with PCL was treated this way.

UNASSIGNED: Infective endocarditis (IE) is an infectious disorder of the innermost lining of the heart that can be fatal if left untreated. Infective endocarditis can spread beyond the endocardium into the myocardium and cause arrhythmias and myocardial wall rupture. Individuals with a history of intravenous drug use are at increased risk of developing IE and are at higher risk of dying, given their limited access to health care and adherence to treatment.
UNASSIGNED: A medicolegal autopsy was performed on a 30-year-old woman with a history of intravenous drug use and recent assault after a hospital admission during which she did not survive resuscitation.
UNASSIGNED: The cause of death was found to be myocardial rupture in the setting of transmural IE. Postmortem imaging showed hemopericardium which was identified grossly with valvular vegetations in the heart. A ventricular wall defect along with transmural abscess formation was identified. Perimortem toxicology was positive for fentanyl, methamphetamine, and benzoylecgonine, a metabolite of cocaine. Postmortem blood cultures were positive for coagulase-negative Staphylococci, Staphylococcus aureus, Candida tropicalis, and Viridians group Streptococci. Postmortem tissue cultures taken from the heart was positive for Candida glabrata and Streptococcus mitis.
UNASSIGNED: The decedent had significant risk factors for IE, such as intravenous drug use and a prior admission to hospital for IE. The organisms identified on culture are in-keeping with the gross findings of IE and the terminal event of myocardial rupture was likely the result of tissue damage resulting from IE.

Left ventricular pseudoaneurysm is a ventricular free wall rupture contained within the adjacent adherent pericardium or scar tissue. Myocardial infarction (MI), cardiac surgery, and chest trauma are the common causes. The most common presenting symptoms of pseudoaneurysms are congestive heart failure, chest pain, and dyspnea, but a small percentage of patients may be asymptomatic. Early diagnosis and treatment are of prime importance because of the tendency of pseudoaneurysms to expand and rupture, with a high mortality rate, especially if left untreated. We present a case of a 65-year-old man who was found to have left ventricular pseudoaneurysm on a follow-up echocardiography within three weeks of an MI. He subsequently underwent patch repair and was discharged after medical optimization. Our case highlights the importance of maintaining a high clinical suspicion of pseudoaneurysm in a patient post-MI, as delayed diagnosis and treatment can be fatal.

Mechanical complications after acute myocardial infarction are well-described yet catastrophic complications of acute coronary syndromes. Uniquely, we describe a rare case of left ventricular free wall rupture at the site of a septic myocardial abscess after an anterior wall myocardial infarction. (Level of Difficulty: Advanced.).

Ventricular free wall rupture (VFWR) is a catastrophic complication of myocardial infarction that poses an imminent surgical emergency. Early recognition is essential as it can expedite the process for a life-saving surgical intervention. We present a case of an acute left VFWR resulting from an underlying myocardial infarction which showed a \"milking-like effect\" during diagnostic angiography. \"Milking-like effect\" is an angiographic phenomenon typically seen in myocardial bridging, which occurs due to the compression of the intramyocardial coronary segments during systole. The presence of this phenomenon is believed to occur due to the extrinsic compression of the coronary by the evolving hemopericardium.

Cardiocutaneous fistula (CF) is a potentially serious and catastrophic complication. Infection the suture line after left ventricular aneurysm repair, presenting with the CF. We present an unusual case of CF due to staphylococcus infection 6 months after repair of a myocardial rupture secondary to dehiscence repair.

We report the incremental value of live/real-time three-dimensional transthoracic echocardiography (3DTTE) over two-dimensional transthoracic echocardiography (2DTTE) in making a definitive diagnosis of left ventricular endocardial rupture with myocardial dissection and contained apical epicardial rupture in an elderly male patient presenting with acute myocardial infarction. To the best of our knowledge, this has not been described previously.

Myocardial rupture after thrombolysis is an often fatal consequence. For patients with myocardial infarction and ischemic stroke within a short timeframe, a catheter-based therapy to retrieve emboli poses a valid therapeutic option in case of a treatment target in CT-Angiography.
