Project description:Occurrence of left atrial myxoma with severe ventricular dysfunction without any obstructive coronary artery disease, as presented in our case, is very rare. It may be due to undiagnosed concomitant dilated cardiomyopathy or unknown cardiodepressant effect of myxoma which warrants further research.

"Left atrial myxoma - A tumor in transit".

Project description:Cardiac myxoma is the most common type of primary cardiac neoplasm. Over 70% of all cardiac myxomas originate from the left atrium (LA) and 18% from the right atrium (RA). Most myxomas present with constitutional, embolic, and obstructive manifestations. We are presenting a case where a part of myxoma got embolized intra-operatively. Using trans-oesophageal echocardiography, we were able to diagnose and image the transit of the tumor from the left ventricle to the left atrium. We removed the embolized tumor from the left atrium and prevented a dreaded complication like stroke, mesenteric ischemia, renal infarct or limb ischemia, which would have resulted in increased morbidity or mortality of the patient.

Left ventricular mass: myxoma or thrombus?

Project description:Patient with embolic episode should always be evaluated for cardiac mass. Mass in left ventricular can be a myxoma or thrombus even in a normal functioning heart. In either case, mobile mass with embolic potential should be surgically resected.

A "Ping-Pong" left atrial thrombus mimicking left atrial myxoma: A case report.

Project description:IntroductionValvular heart disease is highly prevalent, especially in developing countries. Mitral Stenosis (MS) is a condition where there is narrowing of mitral heart valve. Left atrial (LA) thrombus is often seen in severe MS patients.Case presentationA 47-year-old woman complained of palpitation and shortness of breath. The heart sounded irregularly irregular, with grade III/IV diastolic murmurs at the apex. Her electrocardiogram showed atrial fibrillation (AF) with rapid ventricular response Transthoracal echocardiography (TTE) showed severe MS, mild tricuspid regurgitation, and LA thrombus. Mitral valve replacement surgery, tricuspid valve repair, and evacuation of the LA thrombus were immediately done. We evacuated a spherical mass with a size of 4 × 3x2.2 cm, layered and easily separated. Microscopic examination showed extensive fibrin and bleeding with mononuclear inflammatory cells and macrophages, corresponding to a thrombus conclusion.Clinical discussionAtrial thrombus is common in MS patients. The incidence will increase by about two times in patients with AF. TTE is a reliable tool in diagnosing large mobile atrial thrombus and differentiated it from other cardiac masses. However, histopathological examination is still the gold standard to distinguish between LA thrombus and myxoma. Immediate thrombus evacuation and valve replacement, if needed, will give good results and reduce systemic thromboembolism.ConclusionLA thrombus is often seen in a patient with severe MS. Optimal preoperative preparation involves assessing preoperative risk stratification will give good results.

Totally thoracoscopic surgery for treating left atrial myxoma

Project description:Abstract We aimed to summarize the experience of totally thoracoscopic surgery for left atrial myxoma, together with analyzing the safety and feasibility. We retrospectively analyzed the clinical data of 15 patients with left atrial myxoma admitted to our hospital from October 2016 to October 2018. The auxiliary hole was located at the midline of the 5th intercostal space of the right chest. The endoscope hole was located at the front position of the fourth intercostal space. Specimens were sent to the pathology department for pathological examination. All the procedures were completed successfully. Extracorporeal circulation time was 46.5 ± 18.6 minute, cross-clamping time was 20.6 ± 6.7 minute, thoracic drainage fluid was 89+60.2 ml, ventilator assist time was 4.3 ± 2.6 hour, intensive care unit stay time was 14.5 ± 4.2 hour, the average postoperative hospital stay was 5.2 ± 1.2 day. There was no death, or red blood cell transfusion during and after surgery. No postoperative complications were reported by the patients. No recurrence of myxoma, residual shunt in the atrial septum and valvular lesions were found after 3months of postoperative cardiac ultrasound examination. Total thoracoscopic surgery for left atrial myxoma was less invasive with satisfactory cosmetic appearance with feasibility and safety. Besides, it caused no serious complications.

[Determination of residual mass in left ventricle by intraoperative transesophageal echocardiography after a giant and floating left atrial myxoma resection].

Project description:Atrial myxoma is a benign tumor of the heart that occurs primarily in the left atrium. Floating or large left atrial myxomas frequently cause functional mitral stenosis, may also affect mitral valve structure and flow, and lead to mitral regurgitation. Systemic embolization occurs in around 30% of cases either from tumor fragmentation or complete tumor detachment hence it should be removed as soon as it is detected. Intraoperative transesophageal echocardiography has a vital importance in the surgery. After resection of myxoma, intraoperative transesophageal echocardiography must be performed to rule out residual mass. The case here reported is of a 48-year old female, who presented with giant and floating left atrial myxoma. Residue mass was detected with intraoperative transesophageal echocardiography in the left ventricle after the resection of myxoma. Subsequently, the residue mass was successfully removed. Complete resection must be required to prevent possible complications such as recurrence, embolization in atrial myxomas. Transesophageal echocardiography performed intraoperatively is vital importance to confirm that the myxoma is completely resected.
