The possibility of using multiplanar reformations oriented on the axis of heart in diagnosing the common arterial trunk with X-ray computed tomography is substantiated. Examination data of 140 patients aged 1-19 days of life, 3030-3890 g body weight with conotruncal congenital heart diseases was analyzed, and common arterial trunk was detected in 7 patients (4 - boys, 3 - girls). In 5 (72%) patients, it developed mainly from the morphological right ventricle, 1 (14%) - completely from the morphologically right ventricle, and 1 more (14%) - evenly located above the ventricles. In four (57%) cases, the trunk valve had three leaflets, in two (28,5%) cases - two, in one (14,5%) case - four. All the patients had mitral-semilunar fibrous prolongation, intraventricular septal defects, doubled coronary arteries system, and the pulmonary arteries had their origin from ascendant part of common trunk. Pulmonary arteries had also their own common trunk in 4 (57%) cases, separate estuary in 3 (43%) cases. Aortic arc abnormalities included dextral aortic arc (2 cases), discontinuity of aortic arc (1 case), discontinuity of fourth aortic arc with persistence of fifth left aortic arc (2 cases). In general, computed tomographic angiocardiography heart-axis-oriented multiplanar reformations permit full and correct assessment of heart and main vessels, which is important for surgical treatment planning in congenital heart diseases.

Purpose: To investigate right ventricle function in successfully reperfused ST elevated myocardial infarction (STEMI) and to compare reperfusion strategies. Methods: From January 2007 to August 2008, 33 patients with anterior myocardial infarction (MI) and 48 patients with non-anterior myocardial infarction were enrolled in this study. Patients were treated with thrombolytic therapy (TT) or primary percutanaeous coronary intervention (PPCI) (Primary intervention: 16 and 25 patients (anterior and non-anterior consecutively), thrombolytic therapy: 17 and 23 patients (anterior and non-anterior consecutively)). Right ventricle (RV) function was analyzed using tissue Doppler investigation (TDI) after 72 hr of successful reperfusion. Results: There was no difference in right ventricle function assessed by right ventricle TDI Tei index between the PPCI and TT group (0.39±0.20 vs. 0.39±0,17). RV TDI Tei index increased in anterior MI patients treated with either PPCI or TT compared with control group (0.39±0.11 vs. 0.27±0.16, P=0.015 and 0.43±0.18 vs. 0.27±0.16 , P= 0.014 respectively). RV TDI Tei index did not differ between non-anterior MI patients treated with either PPCI or TT and control group (0.38±0.23 vs. 0.27±0.16, and 0.37±0.16 vs. 0.27±0.16, respectively). Conclusions: RV function deteriorated in STEMI compared with healthy controls. Contrary to the expectation, RV dysfunction was observed in anterior STEMI, but not in non anterior MI. There was no difference in RV function between the two treatment modalities.

Congenital Heart Diseases (CHD) lead to various changes in the normal mechanisms of hemodynamics. Pregnancy in women with CHDs is rare. Double Outlet Right Ventricle (DORV) is a rare disorder, in which both the aorta and the pulmonary artery arise from the right ventricle. We present a case of a thirty-year-old pregnant woman who presented to us with 22 weeks of amenorrhea. She had DORV with VSD, which was undiagnosed till she came to our hospital. Double Outlet Right Ventricle (DORV) is a rare congenital heart disease. Pregnancy in a patient with DORV needs early diagnosis and a stepwise multidisciplinary approach for successful outcomes.

Studies about pulmonary hypertension and congenital heart diseases have introduced the concept of right ventricular remodeling leading these pathologies to a similar outcome: right ventricular failure. However right ventricular remodeling is also a physiological process that enables the normal fetal right ventricle to adapt at birth and gain its adult phenotype. The healthy mature right ventricle is exposed to low pulmonary vascular resistances and is compliant. However, in the setting of chronic pressure overload, as in pulmonary hypertension, or volume overload, as in congenital heart diseases, the right ventricle reverts back to a fetal phenotype to sustain its function. Mechanisms include angiogenic changes and concomitant increased metabolic activity to maintain energy production. Eventually, the remodeled right ventricle cannot resist the increased afterload, leading to right ventricular failure. After comparing the fetal and adult healthy right ventricles, we sought to review the main metabolic and cellular changes occurring in the setting of PH and CHD. Their association with RV function and potential impact on clinical practice will also be discussed.
