Project description:We report the clinical case of a patient with acute myocardial infarction due to coronary stent compression as first manifestation of a large thymoma. The patient underwent a coronarography and thrombus aspiration + plain old balloon angioplasty restoring the stent patency. The mass resection was performed through left robotic-assisted thoracic surgery (RATS), resulting in a type A thymoma pT1a, IIb Masaoka-Koga. An uncommon presentation led to early diagnosis and treatment of a thymoma with both oncological and functional significance.
Project description:Biventricular thrombi secondary to anterior myocardial infarction is very rare. We present a patient with giant biventricular thrombi subsequent to an old anterior wall myocardial infarction, and devastating consequences, including acute pulmonary artery and femoral artery embolism. We introduce a unique case report with demonstrative and illustrative images.
Project description:BackgroundThe percentage of women <50 years of age hospitalized with myocardial infarction is increasing. We describe the clinical, morphological, and biological characteristics, as well as the clinical outcomes of this population.Methods and resultsThis prospective, observational study included consecutive women <50 years of age admitted for myocardial infarction at 30 centers in France (May 2017-June 2019). The primary outcome was the composite of net adverse clinical events: all-cause death, cardiovascular death, recurrent myocardial infarction, stent thrombosis, any stroke, or major bleeding occurring during hospitalization with a 12-month follow up. Three hundred fourteen women were included. The mean age was 43.0 (±5.7) years, 60.8% presented with ST-segment-elevation myocardial infarction, 75.5% were current smokers, 31.2% had a history of complicated pregnancy, and 55.1% reported recent emotional stress. Most (91.6%) women presented with typical chest pain. Of patients on an estrogen-containing contraceptive, 86.0% had at least 1 contraindication. Of patients with ST-segment-elevation myocardial infarction, 17.8% had myocardial infarction with nonobstructive coronary arteries and 14.6% had spontaneous coronary artery dissection, whereas 29.3% presented with multivessel vessel disease. During hospitalization, 11 net adverse clinical events occurred in 9 (2.8%) women, but no deaths or stent thromboses occurred. By 12 months, 14 net adverse clinical events occurred in 10 (3.2%) women; 2 (0.6%) died (from progressive cancer) and 25 (7.9%) had an ischemia-driven repeat percutaneous coronary intervention.ConclusionsMost young women with myocardial infarction reported typical chest pain and had modifiable cardiovascular risk factors. History of adverse pregnancy outcomes and prescription of combined oral contraceptive despite a contraindication were prevalent, emphasizing the need for comprehensive cardiological and gynecological evaluation and follow-up.RegistrationURL: https://www.clinicaltrials.gov; Unique identifier: NCT03073447.
Project description:Acute coronary syndrome with precordial ST segment elevation is usually related to left anterior descending artery occlusion, although isolated right ventricular infarction has been described as a cause of ST elevation in V1-V3 leads. We present a case of a patient with previous inferior wall infarction and new acute ST elevation myocardial infarction (STEMI) due to proximal right coronary thrombotic occlusion resulting in right ventricular infarction with precordial ST elevation and sinus node dysfunction. The patient was treated with successful rescue angioplasty achieving resolution of acute symptoms and electrocardiographic abnormalities.
Project description:BackgroundAcute ST-elevation myocardial infarction (STEMI) complicated by infective endocarditis (IE) presents a unique challenge in clinical management, especially when associated with septic embolism leading to coronary artery occlusion.Case summaryThe current clinical report describes the case of a 72-year-old male with a history of arterial hypertension, dyslipidaemia, and severe obstructive sleep apnea. The patient presented with anterior STEMI due to an embolic occlusion in the left anterior descending (LAD) artery, secondary to IE. Coronary angiography revealed embolic occlusion at the LAD origin, and balloon angioplasty without stent placement was performed, considering the embolic and infectious nature of the occlusion. Despite targeted interventions, including broad-spectrum antibiotics and support for cardiogenic shock, the patient's condition deteriorated, leading to cardiac arrest and subsequent death on the fourth day of hospitalization.ConclusionThis case emphasizes the critical need for adapting STEMI management in the presence of IE. It highlights the importance of considering IE in STEMI differential diagnosis and adjusting intervention strategies accordingly.
Project description:Coronary artery aneurysm (CAA) presenting as an ST-elevation myocardial infarction (STEMI) represents a clinical challenge due to the technical difficulties in the percutaneous management of this specific situation. Appropriate treatment for CAA depends on the precise clinical situation and consists of medical management, surgical resection, or/and stent placement. The high rate of complications during percutaneous intervention (distal thrombus embolization, no-reflow phenomenon, stent malposition, or dissection) makes emergent surgery a frequent situation in these cases. We present the case of a 50-year-old man with a STEMI due to thrombotic occlusion of CAA. Specific angiographic techniques and intracoronary imaging help with the percutaneous management of acute thrombotic occlusions in CAA, providing a less invasive approach than emergent surgery.
Project description:We encountered siblings with familial Majewski osteodysplastic primordial dwarfism type II (MOPD II) with acute myocardial infarction in adolescence and in their early 20s. We successfully performed percutaneous and surgical coronary interventions. From these cases, we were able to better understand coronary artery disease of MOPD II and provide better management. (Level of Difficulty: Intermediate.).
Project description:Acute myocardial infarction (AMI) caused by severe stenosis of left main coronary artery (LMCA) presenting with cardiogenic shock and pulmonary edema during noncardiac surgery is uncommon, but a catastrophic event. A 77-year-old male with cholangiocarcinoma underwent hepatectomy. During the surgery, he presented with cardiogenic shock, which did not respond to infusion administration or vasopressor. A transesophageal echocardiogram revealed anterior, septal, and lateral severe hypokinesia and impaired left ventricular function. Emergent coronary angiogram showed severe stenosis of LMCA. The patient underwent primary percutaneous coronary intervention (PCI) under the support of intra-aortic balloon pump, followed by extracorporeal membrane oxygenation. The chest roentgenogram showed pulmonary edema. Two days after PCI, he successfully underwent hepatectomy and bile duct resection. Early identification of the cause of hemodynamic instability during noncardiac surgery and invasive strategy are important for minimizing the myocardial injury and improving clinical outcomes in AMI of LMCA.
