RESUMEN
Worldwide, about 13% of the 200,000 annual recipients of prosthetic heart valves (PHV) present for various surgical procedures. Also, more and more females are opting for pregnancies after having PHV. All patients with PHV present unique challenges for the anesthesiologists, surgeons and obstetricians (in case of deliveries). They have to deal with the perioperative management of anticoagulation and a host of other issues involved. We reviewed the English language medical literature relevant to the different aspects of perioperative management of patients with PHV, particularly the guidelines of reputed societies that appeared in the last 20 years. Regression of cardiac pathophysiology following valve replacement is variable both in extent and timeline. The extent to which reverse remodeling occurs depends on the perioperative status of the heart. We discussed the perioperative assessment of patients with PHV, including focused history and relevant investigations with the inferences drawn. We examined the need for prophylaxis against infective endocarditis and management of anticoagulation in such patients in the perioperative period and the guidelines of reputed societies. We also reviewed the conduct of anesthesia, including general and regional anesthesia (neuraxial and peripheral nerve/plexus blocks) in such patients. Finally, we discussed the management of delivery in this group of high?risk patients. From the discussion of different aspects of perioperative management of patients with PHV, we hope to guide in formulating the comprehensive plan of management of safe anesthesia in such patients.
RESUMEN
We are presenting a case of the right atrial myxoma found in a case of rheumatic heart disease. During transthoracic echocardiography for the evaluation of a suspected rheumatic valvular heart disease, a diagnosis of severe mitral stenosis with severe mitral regurgitation with the right atrial thrombus was made. On transesophageal echocardiography, a pedunculated mass in the right atrium was confirmed. In the course of surgery, it was found that there is a tumor originating from the right atrial appendage (RAA) which was confused with clot on echocardiography. Rheumatic heart disease and myxomas have different etiopathogenesis, and this coexistence has not been reported. Further, right atrial myxoma arising out of RAA is also being reported for the first time.
