VATS thymectomy for thymoma is feasible, safe and has comparable mid-term oncological outcomes to trans-sternal thymectomy. Future research is required to evaluate long-term oncological outcomes of VATS thymectomy for thymoma in national registries and randomized, controlled trials.
A best evidence topic in cardiac surgery was written according to a structured protocol. We addressed the following question: in patients who are diagnosed with carcinoid heart disease (CHD), do valvular surgeries improve their prognosis? Fifty percent of the patients with clinically diagnosed carcinoid syndrome had cardiac involvement which was present either as valvular dysfunction or as cardiac metastases. These patients often require surgery due to their heightened risk of cardiac disease. Altogether 217 relevant papers were identified as a result of the below-mentioned search, of which 10 papers represented the best evidence to answer the question. The author, journal, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses were tabulated. Of the patients who were identified to have carcinoid heart disease in different studies, 193 patients had valve procedure, mainly replacements at tricuspid, mitral and aortic valve positions and either valvuloplasty or replacement at pulmonary valve. Tricuspid and pulmonary valves represented the majority of the excised valves among patients undergoing valvular surgery for CHD. The pathology of carcinoid valve was attributed to the presence of plaque, causing thickening and retraction. Pure regurgitation was the most common finding in all the valves except pulmonary valve which had both stenosis and insufficiency. Thirty-day mortality was 17% (range 1-63%) and long-term survivors were reported to be alive at an average of 58 months (28-80 months) after the valve surgery. The evidence demonstrates that surgical intervention can lead to improved prognosis and reduce the symptoms of heart failure. Postoperative mortality was mainly due to the carcinoid disease itself and not as a complication of the surgery. Therefore, surgery could be considered for symptomatic palliation in carefully selected individuals.
Primary cardiac tumors are very rare, with a reported incidence of 0.15% to 0.2% in autopsy series. They can be life threatening because of myocardial compression and ventricular dysfunction. Once diagnosed during pregnancy, the clinical condition of the baby is monitored because of the risk of rupture of the tumor capsule. The authors report a rare case of a neonate who presented with respiratory and cardiac compromise due to cardiac tamponade necessitating emergency exploration of the pericardium and excision of tumor. A well-encapsulated tumor measuring around 5 cm and bigger than the heart was completely excised. This was diagnosed to be an immature teratoma. Follow-up echocardiogram was normal, and on serial monitoring, alpha-fetoprotein was within normal limits. The baby was discharged home with no complications. Intrapericardial teratoma in neonates is a surgical emergency if presented with significant pericardial effusion. It can be a challenge if diagnosed in utero with rupture before the viability of pregnancy. A multidisciplinary team approach is necessary to manage such situations. Complete excision is necessary because of its association with tissues of malignant potential.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
