Early ventricular fibrillation in patients with acute myocardial infarction: correlation with coronary angiographic findings.

To define coronary angiographic characteristics of patients experiencing early primary ventricular fibrillation (VF) in the acute phase of myocardial infarction we studied 266 consecutive patients without clinical evidence of heart failure. Twenty-six patients (group 1) experienced early (< 12 h from the onset of symptoms of myocardial infarction) primary VF whereas 240 patients (group 2) with the same clinical characteristics served as an appropriately matched cohort. All patients were catheterized before or soon after hospital discharge (1 to 8 weeks after the acute event). There was no significant difference in left ventricular ejection fraction between the two groups of patients (39.6 +/- 6% vs 36.9 +/- 8%, P = ns). Patients with early VF had a significantly greater number of diseased vessels than those without VF (3.38 +/- 1.05 vs 2.03 +/- 1.25, P < 0.001) and a higher coronary arteriographic Gensini score (29.31 +/- 4.80 vs 20.16 +/- 4.14, P < 0.001). The left anterior descending coronary artery was identified as the infarct-related vessel in 53.6% of group 1 vs 44.5% of group 2 patients (P < 0.05). The mean maximal serum creatine kinase values were not significantly different (1897 +/- 1062 vs 1426 +/- 839 IU.l-1, P = ns) between the two groups. These data indicate that patients with early primary VF in the setting of acute myocardial infarction may have more extensive coronary artery disease than similar patients without VF. A worse prognosis could be anticipated for these patients on the basis of worse coronary anatomy.(ABSTRACT TRUNCATED AT 250 WORDS)

Retrograde left atrial catheterization with a new steerable cardiac catheter.

A new type of guiding catheter that may be used for retrograde transmitral catheterization of the left atrium is described. The catheter has a 9F diameter and incorporates a steering arm by means of which the catheter tip may be made to curve through an arc of 0 to 180 degrees, entirely through external manipulation. In this way the tip of the guiding catheter may be positioned below the mitral valve orifice and used for the introduction of a smaller catheter into the left atrial cavity. We tested the system in 20 patients, eight of whom had mitral stenosis. Left atrial catheterization was successful in all cases, and no difficulties were encountered in entry of the left atrium, nor were there any complications during or after the procedure. The technique will provide useful in the study of left atrial function (hemodynamic, electrophysiologic, secretory). It may also be helpful in percutaneous mitral valvuloplasty by permitting retrograde, rather than transseptal, access to the left atrium.

Rocking motion of the right cardiac cavities in Ebstein's anomaly. A specific cineangiographic sign.

In 7 cases of Ebstein's anomaly the right cineangiogram disclosed a big right atrium, the tricuspid valve positioned to the left of the spine and tricuspid regurgitation. The right atrial appendage was nearing the outflow tract of the right ventricle and the pulmonary artery so as the normal U appearance of the right aniograms was abolished. In addition to these signs a very characteristics and almost pathognomonic rocking motion of the radiopaque material, moving from the right atrium towards the right ventricle during ventricular diastole and backwards to the atrium during the next ventricular systole was observed. This sequence of motion gives the impression of a rocking hammock or pendulum.

Multiple coronary arteriovenous fistulae.

A case with multiple congenital coronary arteriovenous fistulae is reported. The right coronary artery was communicating with the right ventricle. The left coronary artery was entering directly into the pulmonary trunk and two terminal branches of the anterior descending into the left ventricle. The direct communication of the left coronary artery without interposition of an accessory artery or a circoid plexus is met for the first time.
