Project description:Large posterior mediastinal masses may lead threatening complications such as critical tracheobronchial compression. Airway management in these individuals is a challenge and being a lower airway obstruction; rescue strategies are limited. We encountered one such case of a large esophageal mucocele causing extrinsic tracheobronchial compression. We have described the anesthetic management of this case using awake fiber-optic assessment followed by intubation. Close communication with the surgical team, meticulous planning of airway management, and early drainage of the mucocele are the cornerstones of management in such patients.

Extrinsic tricuspid valve compression due to an aortic aneurysm causing significant right to left shunt via a patent foramen ovale: a case report.

Project description:BackgroundAortic aneurysms are known to cause compression of adjacent structures including the tracheobronchial tree, oesophagus, and recurrent laryngeal nerve. Extremely rarely, they can lead to compression of the tricuspid valve (TV) annulus. We describe a case where aortic aneurysm caused TV annulus compression and persistent right-to-left shunt through a patent foramen ovale (PFO).Case summaryA 75-year-old female was admitted with headache and dizziness. On examination, she had persistent arterial desaturation with oxygen levels reduced to 69% at rest whilst breathing ambient air. Complete blood count demonstrated polycythaemia (Hb 174 g/L). Right to left cardiac shunt was suspected after significant lung and haematologic pathology was excluded. Transoesophageal echocardiography demonstrated a trileaflet aortic valve with an ascending aorta aneurysm and a stretched PFO with persistent right to left shunt across it. The ascending aortic aneurysm was observed coursing superior to and compressing the TV annulus. Invasive haemodynamic data demonstrated prominent 'a' waves in the right atrium, low RV (12/1 mmHg), and pulmonary artery pressures (14/6 mmHg), reduced cardiac output and significant right to left shunt with Qp:Qs 0.6. Computed tomography (CT) angiogram demonstrated a 5 cm fusiform ascending aorta aneurysm that coursed anteriorly causing TV annulus compression.DiscussionTricuspid valve inflow obstruction associated with a right to left shunt across PFO can be an extremely rare complication of aortic aneurysm. This may result in persistent arterial hypoxaemia and secondary polycythaemia.

Extrinsic compression of the left main coronary artery: A rare cause of cardiogenic shock.

Project description:A left main coronary artery (LMCA) stenosis due to extrinsic compression by mediastinal tumor is a rare finding. In this case reports, we present a 63-year-old woman, who was transferred to the emergency department with chief complains of persistent chest and back pain. An electrocardiogram revealed diffuse ST-segment depression (elevation in lead aVR). Contrast-enhanced computed tomography (CT) showed a huge cystic mass above the left atrium. After the CT examination, she was temporarily in shock. Compression of the LMCA was evident on the CT angiography and a diagnosis of acute myocardial infarction due to compression of the LMCA by a tumor was made. An emergent resection of the tumor was performed. Histopathological assessment of the resected cyst revealed that it was a schwannoma. She made an uneventful postoperative recovery. A follow-up 3-dimensional CT scan performed after the operation confirmed no evidence of LMCA compression.

Left atrial-esophageal fistula repair after radiofrequency catheter ablation for atrial fibrillation.

Project description:Left atrial-esophageal fistula (LAEF) is a rare complication of radiofrequency ablation (RFA) procedures undertaken for atrial fibrillation (AF). This complication is associated with significant morbidity and mortality. Currently, there is no clear consensus on the appropriate management strategy. We report a case of a LAEF that developed in a patient 2 weeks after RFA for medication refractory AF. The patient underwent successful repair of the fistula through a left posterolateral thoracotomy, wherein the esophageal and atrial lesions were repaired primarily with an intercostal muscle flap and bovine pericardial patch to reinforce and prevent recurrence.

Phasic Compression of Left Circumflex Coronary Artery during Atrial Systole.

Project description:Phasic coronary artery compression is typically associated with spasm or myocardial bridging. Compression caused by acquired anatomic changes to the surrounding heart chambers has been reported only infrequently. We present a possibly unique case of phasic compression of the proximal left circumflex coronary artery during atrial contraction in association with a dilated left atrium. A 55-year-old man with multiple cardiac risk factors presented with worsening exertional dyspnea. An electrocardiogram and echocardiogram revealed marked left atrial dilation and a left ventricular ejection fraction of 0.15 to 0.20 with elevated filling pressures. Angiograms showed compression of the proximal segment of the left circumflex coronary artery during late ventricular diastole: the compression occurred in phase with atrial systole, whereas good flow without compression was present during atrial diastole. We attributed this phenomenon to ballooning of the lateral region of the atrial wall toward the atrioventricular groove during atrial systole. The patient complied with antihypertensive therapy, and his status improved after one year. To identify coronary artery compression in the presence of abnormal chamber geometry and to guide the treatment of the contributing medical conditions, we recommend careful analysis of angiographic results.
