Two cases of prosthetic valve dysfunction resulting in acute massive mitral regurgitation are reported; emergency operation was successful in both cases. Survival following complete dislodgement of the occluder of a disc valve, as occurred in one case, does not appear to have been reported before. The diffculty in diagnosis of sudden cardiac decompensation in patients with prosthetic valves is ...

Cardiac resynchronization therapy device (CRT-P and CRT-D) implantation has increased tremendously with increasing operator experience, eligible patients and expansion of indications. Refinements in devices and algorithms now aid physicians to improve biventricular pacing and optimize CRT. We report a case in which an interesting device program was used to achieve biventricular pacing after rep...

In an operation involving coronary bypass grafting, anastomoses to the ascending aorta with saphenous vein or radial artery grafts may increase the possibility of post-operative strokes by the dislodgement of embolic particles into the arterial vasculature. We report a bi-directional single anastomotic technique to decrease the possibility of intra and postoperative strokes and to allow earlier...

Totally implantable venous access devices (TVAD) are commonly used to supply long-term, intermittent central venous access for the administration of chemotherapeutic drugs and intravenous (IV) antibiotics (1, 2). The most common complications related to TVAD implantation are venous thrombosis, extravasation, dislodgement, catheter leakage, and infection. Fracture and embolization of TVAD and re...

Full crowns are often used as treatment in dentistry. Dislodgement of a crown may occur at any time if negative tensile force on the allows displacement. Keeping displaced situ is problematic, tends to come off stump,may be lost and or swallowed. Emergency refixing not feasible available. This note suggests an easy, successful,emergency management temporarily with sugarless chewing gum until ca...

We present a case of successful retrieval of an intracranial stent using a snare wire. A 52-year-old woman presented with left border zone infarction. On cerebral angiography, the C6 segment of the left internal carotid artery (ICA) showed significant stenosis. We attempted stenting of the lesion, although stent dislodgement occurred in the ICA C4 segment. We successfully removed it using a sna...

We report on a 75-year-old woman who successfully underwent cardiac resynchronization therapy. Two weeks after implantation, right continuous pectoral stimulation appeared. Retraction and dislodgement of the right atrial and right ventricular leads as well as coiling of the three leads around the device generator were observed on chest radiography, but, surprisingly, the left ventricular lead r...
