Femoral arterial hemostasis using a collagen plug after coronary artery stent implantation.

We have investigated the safety and efficacy of sealing the femoral arterial puncture site using purified bovine collagen in the catheter laboratory immediately after coronary stent implantation. Ten consecutive patients, mean age 64.6 years, pretreated with heparin, aspirin, and dextran underwent the insertion of a collagen plug immediately after coronary stent implantation. The mean activated clotting time was 512 seconds (range 320-999). Femoral arterial hemostasis was achieved before leaving the catheterization laboratory in nine of ten patients. Seven of these patients received additional mild groin compression with an air cushion compression device after hemostasis was successful. One of ten patients had persistent bleeding after delivery of the collagen plug and later required blood transfusion. The collagen plug may be a useful adjunct to obtaining hemostasis following coronary stent implantation, but further trials are required to test its reliability in fully anticoagulated patients.

Arrhythmia and hypertrophic cardiomyopathy.

Atrial fibrillation is the commonest arrhythmia observed in hypertrophic cardiomyopathy, and is associated with an acute deterioration in symptoms. Digoxin is the drug of choice in established atrial fibrillation and amiodarone the drug of choice in paroxysmal atrial fibrillation and ventricular arrhythmia. Non-sustained ventricular tachycardia occurs in 20% of patients and is the single best predictor of sudden death in adults. Sustained monomorphic ventricular tachycardia occurs only rarely. The mechanism of sudden death is likely to involve initiating factors such as arrhythmia and peripheral autonomic dysfunction causing haemodynamic instability and myocardial ischaemia. Myocardial disarray may provide the arrhythmogenic substrate such that haemodynamic instability and ischaemia results in ventricular fibrillation and sudden death.

Pseudoxanthoma elasticum presenting with myocardial infarction.

A 31 year old man presented with an anterior myocardial infarction. He had a history of recurrent gastrointestinal bleeding of obscure cause since childhood and peripheral vascular disease. A clinical diagnosis of the type 1 dominant form of pseudoxanthoma elasticum was supported by histological data from skin biopsy.
