Incidental finding and conservative management of left main coronary atresia in an adult patient: a case report.

Project description:BackgroundLeft main (LM) coronary atresia (LMCA) is a rare coronary anomaly where the LM is congenitally absent and a variable clinical spectrum can follow. The diagnosis of LMCA is generally made in youth because of the development of symptoms, but very rarely in adulthood. In symptomatic patients, surgical revascularization is recommended, whereas, in asymptomatic patients with LMCA and without inducible myocardial ischaemia, preventive surgical treatment is controversial.Case summaryA 58-year-old male patient with aortic ectasia detected during an echocardiogram performed to evaluate a hypertension-related preclinical cardiac damage and, due to this finding, an echocardiographic follow-up was suggested. Three years later, he was admitted to undergo coronary angiography (CA) after the computed tomography finding of a suspected occlusion of the LM with collateral circulation from right coronary artery (RCA) to left anterior descending and circumflex arteries. CA confirmed an LMCA and the RCA provided blood supply to the left coronary artery through collaterals whose calibre was similar to that of the target left-sided vessels. No obstructive coronary artery disease was detected. In order to detect potential myocardial ischaemia, a technetium-tetrofosmin cardiac single-photon emission computed tomography during maximal exercise-stress test was performed and it did not show a perfusion defect. Medical management with scheduled follow-up visits was deemed to be the best therapeutic option.DiscussionLMCA is a rare anomaly where LM is absent and the RCA provides collateral circulation for left coronary artery. In asymptomatic patients, preventive surgical treatment is controversial.

Percutaneous transvenous angioplasty of left innominate vein stenosis following right side permanent pacemaker implantation- a left femoral vein to left axillary vein approach.

Project description:Central venous stenosis after the insertion of a permanent pacemaker is a well recognized complication. This late complication is encountered when there is a need to change the pacemaker lead or extract it. We describe a young male who had such a complication after many years after right side pacemaker implantation. The lesion was managed percutaneously leading to placement of a new lead from the left side.

Fat embolism in right internal jugular vein: incidental ultrasound finding during internal jugular vein cannulation.

Project description:BackgroundWe report a case study of fat embolism seen on ultrasound at right internal jugular vein during central venous cannulation in a patient diagnosed with fat embolism syndrome. This case demonstrates the importance of ultrasound for evaluation of trauma cases with suspicion of fat embolism.Case presentationA 23-year-old trauma patient with closed fracture of left femoral shaft and left humerus presented to our emergency department (ED). 11 h after admission to ED, patient became confused, hypoxic and hypotensive. He was then intubated for respiratory failure and mechanically ventilated. Transesophageal ultrasound revealed hyperdynamic heart, dilated right ventricle with no regional wall abnormalities and no major aorta injuries. Whole-body computed tomography was normal. During central venous cannulation of right internal jugular vein (IJV), we found free floating mobile hyperechoic spots, located at the anterior part of the vein. A diagnosis of fat embolism syndrome later was made based on the clinical presentation of long bone fractures and fat globulin in the blood. Despite aggressive fluid resuscitation, patient was a non-responder and needed vasopressor infusion for persistent shock. Blood aspirated during cannulation from the IJV revealed a fat globule. Patient underwent uneventful orthopedic procedures and was discharged well on day 5 of admission.ConclusionsPoint-of-care ultrasound findings of fat embolism in central vein can facilitate and increase the suspicion of fat embolism syndrome.

Incidental Anomalous Left Coronary Artery in a Transplanted Heart.

Project description:Anomalous coronary artery is an uncommon congenital cardiac anomaly that is often detected incidentally on coronary angiography. It has rarely been reported in the donor heart of patients who have undergone cardiac transplantation. Here, we report a case of a 72-year-old patient who received a second heart transplant and has been identified to have an anomalous left main coronary artery originating from the right coronary sinus on postoperative coronary angiography.

Incidental Finding of Left Ventricular False Chamber: Diagnostic and Therapeutic Implications.

Project description:We present the case of a 75-year-old man with incidental finding of a left ventricular false chamber at echocardiography. A multimodality imaging approach including also transesophageal echocardiography and cardiac magnetic resonance imaging allowed to better characterize the lesion and identify it as a pseudoaneurysm. Surgery showed an infective aetiology, which is rare, due to the finding of a large abscess in the cavity.

Incidental Finding of the Anomalous Origin of Left Main Coronary Artery from Pulmonary Artery in an Adult Presenting with Arrhythmia-Induced Myocardial Ischemia.

Project description:Anomalous origin of the left main coronary artery from the pulmonary artery (ALCAPA) is a rare congenital coronary anomaly with high mortality. It is associated with cardiovascular complications and is usually diagnosed soon after birth. Those who survive into adulthood can present with signs of myocardial infarction, heart failure, mitral regurgitation, severe pulmonary hypertension, or sudden cardiac death. We present a 53-year-old female presenting with atrial fibrillation and found to have an incidental diagnosis of ALCAPA who refused surgical correction. We also review the epidemiology, diagnosis, age-based clinical presentations, and treatment options for ALCAPA.

Acute Thrombosis of Left Portal Vein during Right Portal Vein Embolization Extended to Segment 4.

Project description:Portal vein thrombosis (PVT) is an uncommon, but potentially devastating complication of portal vein embolization (PVE). Its occurrence relates to both local and systemic risk factors. In the setting of PVE, precipitating factors include injury to the vessel wall and reduced portal flow. Contributory factors include portal hypertension, hypercoagulopathy, inflammatory processes, malignancy, pregnancy, oral contraceptive use, and asplenia. The goal of therapy is to prevent thrombus progression and lyse existing clot. Hepatectomy is impossible if adequate recanalization has not occurred and/or overt portal hypertension develops. The mechanisms for thrombus development, its diagnosis, management, and prognosis are discussed.

Large, calcified aneurysm of the left ventricle: Case report of an incidental finding.

Project description:The case is of an 88-year-old female patient with an accidental finding of a large, calcified aneurysm near the cardiac apex. Differential diagnoses can be made with false aneurysms and congenital diverticulums. Imaging modalities beneficial for diagnosing LVA are ultrasound, X-rays, CT, MRI, including PET/CT for oncology patients.

A rare case of anomalous origin of the left main coronary artery in an adult patient.

Project description:Anomalous origin of left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital anomaly that causes a left-to-right shunt via the coronary system, resulting in coronary steal. We report an unusual case of a healthy 48 years-old patient presenting with dyspnea on exertion and mild chest pain who underwent surgical correction of this rare anomaly. Multiple procedures have been proposed in adults with ALCAPA. Although re-implantation of the left main coronary artery (LMCA) to the aorta remains the most physiological correction for this anomaly, the combination of LMCA ligation and coronary artery bypass grafting provides a dual coronary flow system and is preferable when re-implantation is impossible.
