The Use of Cangrelor as Bridge Antiplatelet Therapy in a Patient with Recent Percutaneous Coronary Intervention for Acute Coronary Syndrome, Who Developed Esophageal Perforation After Transesophageal Echocardiography.

Dual antiplatelet therapy (DAPT) is a vital part of the pharmacological management in patients with coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI). While early discontinuation of DAPT increases ischemic risk, some patients on DAPT may require urgent surgery, necessitating its interruption. Cangrelor, an intravenous P2Y12 antagonist, provides strong platelet inhibition within minutes and platelet activity normalizes within one hour after the cessation of the drug. Bridging antiplatelet therapy with cangrelor has been increasingly studied as an alternative option to ensure the continuation of platelet inhibition in CAD patients who require discontinuation of DAPT. The present patient, with a recent history of PCI for acute coronary syndrome, experienced a significant esophageal perforation following transesophageal echocardiography (TEE). This severe complication was effectively managed endoscopically, and as part of the recent PCI treatment, prolonged cangrelor infusion was successfully utilized with no thrombotic or bleeding events throughout the management of the complication.

Thyroid Functions Are Associated with All-Cause Long-Term Mortality in Elderly Patients with ST-Segment Elevation Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention.

OBJECTIVE: Our aim in this study was to show the relationship between long-term all-cause mortality and thyroid functions in the elderly patient group that underwent primary percuta-neous coronary intervention with the diagnosis of ST-segment elevation myocardial infarction. METHODS: Two-hundred seventy patients over 65 years of age who underwent primary percutaneous coronary intervention with the diagnosis of ST-segment elevation myocardial infarction were analyzed retrospectively. After applying the exclusion criteria, 198 patients were included in the study. The patients were divided into 2 groups according to their out-of-hospital mortality status. Angiographic, laboratory, echocardiographic, and electrocardiographic data were analyzed. RESULTS: The mean age of 198 patients in the study was 72.5 ± 6.6 years, and the median follow-up time was 101.7 months. Age was higher in the deceased group (70.4 ± 5.4 vs. 74.5 ± 6.9, P < 0.001). In multivariate analysis, age (odds ratio: 1.59, P = 0.003), insulin (odds ratio: 2.561, P = 0.016), angina balloon time (odds ratio: 1.134, P = 0.002), number of serious stenoses (odds ratio: 1.702, P = 0.003), creatinine (odds ratio: 3.043, P < 0.001), and fT4 (odds ratio: 2.026, P = 0.026) were determined as independent predictors of mortality. The fT4 level was correlated with the uric acid level (R: 0.182, P = 0.02) and the fT3 level was correlated with albumin (R: -0.253, P = 0.001) and creatinine (R: -0.224, P = 0.003) levels. A fT4 level cutoff value of 0.99 ng/mL had a sensitivity of 76%, a specificity of 54%, and an area under the curve of 0.675 in predicting mortality. In Kaplan-Meier analysis, fT4 elevation was strongly associated with mortality (P = 0.01). CONCLUSION: In our study, subclinical values in thyroid functions were found to be associated with increased mortality, apart from known factors in elderly patients who underwent primary PTCA with the diagnosis of ST-segment elevation myocardial infarction.

Long-Term Observational Study of the Isolated Ostial Diagonal Stenosis in Patients with Chronic Coronary Syndrome.

OBJECTIVE: Isolated ostial diagonal stenoses are very rare lesions in which percutaneous intervention could cause significant vessel compromise, and the long-term results have been reported in a few studies. This study sought the characteristics and long-term follow-up of the patients with isolated osteal diagonal stenosis regarding percutaneous coronary intervention and presence of angina. METHODS: The study was an observational retrospective study conducted between January 2014 and December 2020. A total of 9769 patients who underwent coronary angiography were analyzed, and 87 patients had isolated diagonal stenosis. The patients were evaluated according to treatment modality and angina severity in long-term pattern. RESULTS: Median follow-up time was 36 months. A total of 54 (83.1%) patients were followed up with only medical treatment, and 11 (16.9%) patients underwent revascularization in addition to medical treatment. The degree of stenosis of the diagonal artery was significantly higher in the percutaneous coronary intervention group than medical group (P = 0.002) and the patients with wider reference diameter of diagonal artery complaint of more angina (P = 0.007). Class I angina was significantly higher in percutaneous coronary intervention group than medical and the patients with no angina were significantly higher in medical group than percutaneous coronary intervention group. CONCLUSION: Percutaneous coronary intervention was mainly performed for diagonal arteries with a higher degree of stenosis; however, the patients who underwent percutaneous coronary intervention had angina more than 50% rates. Furthermore, the patients with ongoing angina had a larger diameter of the diagonal artery regardless of the type of treatment.

A successful endovascular treatment of a patient with extended-spectrum beta-lactamase positive Escherichia coli related emphysematous distal abdominal aortitis rapidly progressing to a saccular aneursym.

Infectious aortitis is a rare disease and associated with adverse clinical outcomes. A 66-year-old man was admitted to the emergency department with abdominal and lower back pain, fever, chills, and anorexia continuing for a week. A contrast-enhanced computed tomography (CT) scan of the abdomen showed multiple periaortic enlarged lymphatic nodes, mural wall thickening, and gas collections in the infrarenal aorta and proximal segment of right common iliac artery. The patient was hospitalized with the diagnosis of acute emphysematous aortitis. During hospitalization, extended-spectrum beta-lactamase-positive Escherichia coli was grown in all blood and urine cultures. Despite sensitive antibiotherapy, abdominal and back pain, inflammation biomarkers, and fever of the patient were not improved. Control CT demonstrated a newly developed mycotic aneurysm, increased intramural gas collection, and periaortic soft-tissue thickening. Urgent vascular surgery was recommended to the patient by the heart team, but the patient rejected surgery due to the high perioperative risk. Alternatively, an endovascular rifampin-impregnated stent-graft was successfully implanted and antibiotics were completed at 8 weeks. After procedure, inflammatory indicators were normalized and clinical symptoms of the patient were resolved. No microorganism grew on control blood and urine cultures. The patient was discharged with a good health. Learning objective: Aortitis should be suspected in patients who present with fever, abdominal and back pain, especially in the presence of predisposing risk factors. Infectious aortitis (IA) accounts for a small part of all aortitis cases and the most common causative microorganism is Salmonella. The mainstay treatment of IA is sensitive antibiotherapy. Surgery may be required in patients who are unresponsive to antibiotics or develop aneurysm. Alternatively, endovascular treatment can be performed in selected cases.

A Transient Inferolateral ST-Segment Elevation on the Electrocardiogram Due to an Iatrogenic Left-Sided Pneumothorax After an Urgent Tracheostomy in a Patient with Metastatic Hypopharynx Cancer.

The presence of ST-segment elevation on the electrocardiogram alerts physicians in patients with chest pain. Emergency coronary angiography is usually performed in these patients. However, there are many conditions that cause ST-segment elevation on the electrocardiogram, such as pericarditis, hyperkalemia, Brugada syndrome, hypothermia, and early repolarization. Pneumothorax is a rare complication of tracheostomy and its symptoms are sudden chest pain and dyspnea. Also, it has been known that pneumothorax may cause ST-segment changes on the electrocardiogram. We presented a transient inferolateral ST-segment elevation on the electrocardiogram due to an iatrogenic left-sided pneumothorax after an urgent tracheostomy in a patient with metastatic hypopharynx cancer and normal coronary angiogram.

The Relationship Between Coronary Anatomy and Angina Pectoris During Stent Balloon Dilatation in Patients Undergoing Percutaneous Coronary Intervention.

OBJECTIVE: Angina pectoris (AP) is defined as a clinical symptom characterized by sensations such as pressure-heaviness, burning, squeezing, or discomfort in different parts of the body, including the retrosternum, chest, jaw, neck, shoulders, and back. Limited publications exist on the impact of coronary artery disease localization on the placement, character, and severity of AP. This study aimed to investigate the relationship between the frequency of AP development due to myocardial ischemia during percutaneous coronary intervention (PCI), its character, severity, localization, and coronary anatomy. METHODS: A total of 128 patients were included in the study, with 146 lesions treated among them. RESULTS: Among patients who underwent PCI of the right coronary artery (RCA), 31.1% reported no complaints. Similar rates were observed in patients undergoing PCI of the left anterior descending (LAD) and circumflex (Cx) arteries, at 23.7% and 19.1%, respectively. Pressure-heaviness was frequently observed in PCI of the LAD and Cx arteries, while burning was the dominant symptom description in PCI of the RCA. The isolated retrosternal and left thoracic regions were the most common localizations in all main coronary arteries. Epigastric localization occurred most frequently in PCI of the RCA. In terms of the severity of angina, no significant difference was observed between the three coronary arteries. CONCLUSION: Pressure-heaviness angina was commonly observed during PCI of the LAD and Cx, while burning angina was frequent during PCI of the RCA. The severity of AP was similar across the three main coronary arteries.
