[Thrombosis within the area of muscle bridge as a cause of myocardial infarction]. / Zakrzep w obszarze mostka miesniowego jako przyczyna zawalu serca.

Muscle bridge with concomitant sclerotic lesions may cause myocardial infarction (MI). We present a case of 70 year-old woman, who suffered from MI due to sclerotic lesion located within the anterior descending artery, right above the muscle bridge. Implanting two drug eluting stents resulted in restoration of proper flow through the vessel, widening the sclerotic lesion and the area of muscle bridge.

Subclavian artery stenosis as a cause of acute coronary syndrome in a patient after coronary artery bypass grafting.

We described a case of a 74-year-old man who suffered from acute coronary syndrome 7 years after coronary artery bypass grafting. The patient underwent angioplasty of the obtuse marginal branch of the left coronary artery from venous graft access, which did not result in relief of ailments. Only angioplasty of the narrowed subclavian artery caused an improvement in the patient's condition. The clinical significance of narrowing within the subclavian artery in patients after the procedure of implanting the left subclavian artery into the coronary artery system was discussed.

[Repeat angioplasty of the left anterior descending coronary artery due to restenosis. How many times could we do it?]. / Wielokrotna angioplastyka tetnicy zstepujacej przedniej. Ile razy nalezy poszerzac tetnice z powodu restenozy?

Coronary angioplasty is widely accepted method of myocardium revascularisation. Repeat restenosis is often an indication for surgical treatment. Unfortunately, some patients are not treated surgically for various reasons. This leads to major therapeutic problems. We present a case of a 79-year-old female with repeat angioplasty done 6 times to the left anterior descending artery due to acute coronary syndromes in a 4-year period. The patient did not agree to recommended surgical treatment. We observed gradually deteriorating left ventricular function. The patient finally agreed to surgery, but left ventricle injury added to other clinical problems resulted in disqualification from operation.
