Prosthetic valve thrombosis (PVT) can be a life-threatening complication that requires immediate treatment. We present a case of 57-year-old woman with tricuspid PVT who was definitely diagnosed by multi-detector-row computed tomography limited with echocardiography. The patient was treated successfully with an alternative approach using low molecular weight heparin bridging therapy followed by intensifying anticoagulation alone.

Preservation of the subvalvular apparatus has the merits of postoperative outcomes during mitral valve replacement for mitral regurgitation. We performed mitral valve replacement with anterior and posterior leaflet chordal preservation in a 65-year-old woman. On the 2nd postoperative day, routine postoperative trans-thoracic echocardiography showed an unknown aortic subvalvular mobile mass. We report a case of a remnant mitral subvalvular apparatus detected by echocardiography after chordal preserving mitral valve replacement which was confused with postoperative aortic valve vegetation.

Background Evaluation of acute chest pain in emergency department (ED), using limited resource and time, is still very difficult despite recent development of many diagnostic tools. In this study, we tried to determine the applicability of new semi-automated cardiac function analysis tool, velocity vector imaging (VVI), in the evaluation of the patients with acute chest pain in ED. Methods We prospectively enrolled 48 patients, who visited ED with acute chest pain, and store images to analyze VVI from July 2005 to July 2007. Results In 677 of 768 segments (88%), the analysis by VVI was feasible among 48 patients. Peak systolic radial velocity (Vpeak) and strain significantly decreased according to visual regional wall motion abnormality (Vpeak, 3.50 ± 1.34 cm/s for normal vs. 3.46 ± 1.52 cm/s for hypokinesia, 2.51 ± 1.26 for akinesia, p < 0.01; peak systolic radial strain -31.74 ± 9.15% fornormal, -24.33 ± 6.28% for hypokinesia, -20.30 ± 7.78% for akinesia, p < 0.01). However, the velocity vectors at the time of mitral valve opening (MVO) were directed outward in the visually normal myocardium, inward velocity vectors were revealed in the visually akinetic area (VMVO, -0.85 ± 1.65 cm/s for normal vs. 0.10 ± 1.46 cm/s for akinesia, p < 0.001). At coronary angiography, VMVO clearly increased in the ischemic area (VMVO, -0.88+1.56 cm/s for normal vs. 0.70 + 2.04 cm/s for ischemic area, p < 0.01). Conclusion Regional wall motion assessment using VVI showed could be used to detect significant ischemia in the patient with acute chest pain at ED.

In this case report, we describe a 71-year-old woman with right conal coronary artery-to-pulmonary trunk fistula. She visited the outpatient clinic of the nephrology department for long-term management of renal dysfunction. On transthoracic echocardiography (TTE) conducted as a part of cardiac evaluation, an abnormal Doppler color flow taking a course toward echocardiographic probe was incidentally detected outside the main pulmonary trunk, giving an impression of congenital coronary arteriovenous (AV) fistula. Computed tomography coronary angiography confirmed the presence of congenital coronary AV fistula from a conal branch of the right coronary artery to the main pulmonary trunk in the form of a ground cherry. Although the direction of Doppler color flow is not usual (i.e. toward, not away from, echocardiographic probe) in this case, congenital coronary AV fistula should be in the first priority among potential diagnoses when an abnormal Doppler color flow was found near the main pulmonary trunk on TTE.
