Double ventricular rupture after acute myocardial infarction: A rare case report

A previously asymptomatic 53-year-old male presented 5 days after an acute anterior wall myocardial infarction, who was fibrinolytic naïve, with worsening dyspnea. Transthoracic echocardiographic evaluation revealed rupture of the interventricular septum and pseudoaneurysm of the left ventricle, confirmed by angiography. Coronary angiogram revealed multivessel disease. The patient underwent successful closure of ventricular septal rupture with repair of pseudoaneurysm and saphenous vein grafts to posterior descending branch of right coronary artery and obtuse marginal branch of left circumflex artery. Double ventricular ruptures following acute myocardial infarction are very rare with a reported incidence of 0.3% from various series in the revascularization era. They are also associated with exceedingly high mortality rates reaching up to 50%, even when intervened emergently.

Quadrofurcation of the left main coronary artery

A 45-year-old man was admitted to our hospital’s cardiology service suffering from an intermittent chest pain and exertional dyspnoea. The patient was referred to our computed tomography (CT) department to make further evaluation with coronary computed tomography angiography (CTA). In his coronary CTA exam, there were no significant stenosis. But we saw an interesting view at the side of the left main coronary artery (LMCA) division. An early well-developed first obtuse marginal (OM1) branch of left circumflex artery (LCX) was mimicking quadrofurcation of LMCA with the other three main branches; LCX, left anterior descending artery (LAD) and ramus intermediate (RI) (Figs. 1A–D). Occasionally, the LMCA trifurcates into the LAD, LCX, and RI. There are many anatomical variations of coronary arteries. While some of them are very important and life-threatening, the others have no clinical importance. Although the variation in our case belonged to the second group which has no clinical importance, it should be considered before possible coronary arterial interventions. Multislice ECG-gated cardiac CT is rapidly emerging as a useful noninvasive tool for the evaluation of the coronary arterial tree. Multislice CT may be superior to catheter angiography in defining the ostial origin, proximal course, and termination of the coronary arteries and may be the ‘gold standard’ for detecting coronary anomalies. We demonstrate an interesting coronary variation with 320-multidetector CT in our case.

A Study of Coronary Artery Predominance and Its Clinical Importance

With the increasing trends of coronary heart diseases, the knowledge of variations in the coronary arteries is of paramount importance when considering the various surgical procedures. This study was conducted to know the variations in coronary artery dominance pattern. 77 formalin fixed hearts were dissected. Origin and area of distribution of posterior interventricular artery and SA nodal artery were noted. In 64 hearts (83.11%) posterior inter ventricular artery was a branch of right coronary artery and in 13 hearts (16.88%) it was a branch of left circumflex artery. SA nodal artery was a branch of dominant artery in 46 hearts (59.74%). It arose from non-dominant artery in 29 hearts (37.66%). In the remaining 2 hearts (2.6%) SA nodal artery was a branch from both.

Recurrent cardiac chloroma presenting as acute chest pain

### Learning Point for Clinicians Granulocytic sarcoma should be a part of the differential diagnosis of patients who present with mass lesions after allogeneic transplant for chronic myeloid leukemia, even in the absence of hematologic relapse. A 41-year-old man presented to the hospital with sudden onset of chest tightness. His past medical history was notable for diagnosis of chronic myeloid leukemia (CML), made at 33 years. He was treated with imatinib, dasatinib and allogeneic peripheral blood stem cell transplant (PBSCT) with HLA mismatched, unrelated donor and he was still in complete hematologic response. On admission, his vital signs and cardiac enzymes were normal. Right ventricular hypertrophy was newly developed compared with his previous electrocardiography. He got an urgent coronary angiography due to ongoing chest pain, and the result showed no significant stenosis but anomalous tumor feeding vessels from left circumflex artery. A huge branch of left circumflex artery was supplying …

Coronary-to-Bronchial Artery Fistula

The aim of this study was to evaluate the incidence of coronary-to-bronchial artery fistula (CBF) and clinical significance in 1300 patients examined with 64-multidetector computed tomography (MDCT) coronary angiography. One thousand three hundred ten patients underwent coronary MDCT for atypical chest pain or screening. Volume-rendering and multiplanar reconstruction images were reviewed, and subsequent cineangiographies were compared. Eight cases of CBF were detected-6 originated from the left circumflex artery, and 2 originated from the right coronary artery. A hypertrophied anomalous branch of left circumflex artery was observed in 1 case, and underlying bronchiectasis was noted. Seven cases had a thin-wall communicating vessel. Subsequent cineangiography revealed identical appearance with MDCT reconstruction images. The incidence of CBF (0.61%) in this study is similar to those of a few cineangiographic studies in the literature. Our study showed that 64-MDCT coronary angiography is an accurate and noninvasive tool for detection of CBF.
