Short-term angiographic and long-term clinical follow-up of a patient with a malexpanded vein graft stent.

Optimal stent expansion is considered imperative today in order to prevent subacute stent thrombosis and allows us to minimize antithrombotic therapy. The short-term angiographic and long-term clinical follow-up of a patient with a suboptimally expanded vein graft balloon expandable stent is presented. Intensive antithrombotic treatment along with unimpeded blood flow were probably highly beneficial.

Cortical blindness following coronary arteriography: a rare but self-cured complication. Two case reports.

The rare and self-cured complication of cortical blindness following coronary arteriography is presented in 2 patients who underwent cardiac catheterization. Both patients were submitted to an aortocoronary bypass grafting procedure a few years before and were under clinical investigation for a new onset of unstable angina pectoris.

Coronary artery discrete aneurysms, ectasia, and occlusive disease ane extensive arteriomegaly. Correlation, constellation, or coincidence? A case report.

The case of a sixty-five-year-old man with discrete coronary aneurysms, associated with coronary artery ectasia, stenoses, and total occlusion of the left anterior descending artery, that resulted in an acute anterior myocardial infarction, is presented. Aortography and digital subtraction angiography revealed marked aortic and iliac elongation, tortuosity, and aneurysmal dilatation as well as dilatated femoral and popliteal arteries with aneurysmal dilatation in places. It is considered that the case reflects the broad spectrum of atherosclerosis manifestations.

Single coronary artery from the right sinus of Valsalva, associated with absence of left anterior descending and an ostium-secundum-type atrial septal defect: a rare combination. A case report.

A case of single coronary artery from the sinus of Valsalva, with an anomalous origin of the left circumflex coronary artery from the just proximal portion of the right coronary artery, absence of the left anterior descending, and an ostium-secundum-type atrial septal defect is presented. This combination seems to be very rare.

Functional dominance of the right coronary artery: incidence in the human heart.

After injection of radiopaque medium, 200 human hearts were studied by direct observation and x-ray analysis. The right coronary artery (RC) was dominant in 178 of these hearts as characterized by giving off the typical posterior interventricular artery (PIV), the posterior descending artery. Within this group, 19 specimens had right coronary arteries that gave off both a large posterior interventricular artery (LPIV) and a branch that continued beyond the crux termed a large extension of the right coronary (LERC).

Posterior right diagonal artery.

Background: There is general confusion about a branch of the posterior segment of the right coronary artery that has been referred to as 1) the lower trunk of a divided right coronary artery; 2) a posterior reflection of the right marginal artery; 3) the ramus lateralis; and 4) a posterolateral branch or a posterior descending artery.

Materials: Three hundred human hearts were studied by direct observation, X-ray films, and corrosion casting.

Results: This branch of the right coronary artery arises either after the right marginal artery (in 84% of hearts) or it constitutes the continuation of this artery in the remaining 16%.

Coronary angioplasty in the elderly: immediate and long-term results.

Coronary angioplasty was performed in 37 elderly patients (> sixty-eight years) with unstable or stable angina, refractory to medical treatment. History of myocardial infarction was present in 38% and of previous bypass surgery in 5% of patients. Coronary angiography revealed single-vessel disease in 22 (59%) and multivessel disease in 15 (41%) of patients.

Double left anterior descending artery originating from the left and right coronary artery: a rare coronary artery anomaly.

A case of double left anterior descending coronary artery is presented. The double artery originated from the left main stem and the right coronary artery. There were no stenoses on these two arteries.

"Torsades de pointes" invariant angina: successful treatment with verapamil.

A patient had continuous paroxysms of the specific ventricular arrhythmia of the "Torsades de Pointes" type during attacks of variant angina. The arrhythmia was refractory to lidocaine and procainamide and only responded dramatically to verapamil, initially intravenous and afterwards oral. The low success rate in the treatment of such arrhythmias by other drugs and available experimental data suggest that verapamil should be further evaluated.

Mitral valvotomy in a patient with dextroversion and skeletal chest deformities.

A case of acquired mitral stenosis in a 29-year-old male with cardiac dextroversion and bone abnormalities of the chest is described. Open mitral valvotomy through a median sternotomy was planned but could not be executed and a closed valvotomy was easily performed.
