Anatomical Imaging

Doing the heart three-dimensional CT imaging (3DCT), the writers found 3DCT can clearly show the left ventricular apical thinning (LVAT). Purpose: To observe the shape of LVAT and measure related parameters in the end-systolic and end-diastolic phases. Methods: 12 cadaveric heart specimens were observed, and the thickness of LVAT was measured, as well as the thickest myocardium of left ventricle (TMLV). There are 69 cases imaging data of the end-systolic and end-diastolic phases without heart diseases from PACS in our hospital, with multiplanar reconstruction (MPR), Volume rendering (VR), the LVAT was clearly shown and measured. Measuring parameters include the thickness of LVAT, TMLV and the distance between the LVAT and the anterior descending branch of left coronary artery (DBLCA). Statistical comparisons were made. Results: In all cadaveric heart specimens of 12 cases were found the LVAT, the thickness of LVAT, TMLV was 1.74 mm ± 0.32 mm, 13.07 mm ± 1.48 mm. 3DCT clearly showed the LVAT in the 69 cases, whose thickness was 1.17 mm ± 0.43 mm in the diastole phase and 1.19 mm ± 0.48 mm in the systole phase. The thickness of TMLV was 12.02 mm ± 1.66mm, and the distance between the LVAT and DBLCA was 13.70mm ± 3.78 mm in the diastole phase. There were not significant differences in the LVAT thickness between systole and diastole phases (t = 0.366, p > 0.5), but there are significant differences in measuring the thickness of myocardium between the anatomy and 3DCT (t = 2.210, 0.01< P<0.05). Conclusion: The LVAT can be clearly shown by anatomy and 3DCT, and its thickness does not change in the end-systolic and end-diastolic phases.

Diagnostic Modalities

ALCAPA syndrome was characterized by anomalous origin of left coronary artery from pulmonary artery. Its clinical presentation is varied and although it is an anomaly of congenital origin, it is not exclusive to pediatric ages. Its epidemiological documentation is difficult. We aimed to make the non-invasive diagnosis of the ALCAPA syndrome and its variants. An observational, prospective and cross-sectional study was conducted with 31 patients with a positive echocardiographic diagnosis of ALCAPA syndrome at Pediatric Cardio Center “William Soler” from 2005 to 2018. The variables with significance for diagnosis were the echocardiographic visualization of the anomalous connection and the reversed flow in the left coronary artery. The variables with significance for typing were age at diagnosis, ischemia in the electrocardiogram, echocardiographic visualization of left ventricle papillary muscles fibrosis, presence of severe mitral regurgitation, left ventricle spheroidal remodeling, left ventricle ejection fraction, left ventricular end-diastolic volume index, and left ventricular end-diastolic diameter index. An algorithm integrated by various diagnostic modalities associated with echocardiography as a tool for the detection of ALCAPA was developed. The documentation of the diagnostic and classificatory aspects of the syndrome is possible by detecting echocardiographic elements in conjunction with electrocardiographic and radiological aspects.

The Right

In the present study the most outstanding anatomical findings of the heart of a giraffe are described. Two papillary muscles were found in the right ventricle, namely magnus and subarterial. There were no papillary parvi muscles. The supraventricular crest gave insertion to various tendinous chords. These chords fixed the angular cusp of the right atrioventricular valve. The pectinate muscles were better developed in the left auricle than in the right one. Within the left ventricle two big papillary muscles were found as well as a notorious septomarginal trabecula. The left coronary artery irrigated the majority of the heart’s territory. It gave origin to the interventricular paraconal branch and to the circumflex branch. The latter gave off the branch of the left ventricular border and the interventricular subsinosal branch.

AbstractThe aim of this study was to determine the left ventricular myocardial deformation and segmental myocardial dysfunction by speckle tracking echocardiography and tissue Doppler imaging among the operated patients with anomalous origin of the left coronary artery from the pulmonary artery. The study was conducted on 12 patients diagnosed with anomalous origin of the left coronary artery from the pulmonary artery, who had been operated upon between 2001 and 2013 at the medical centres of Shiraz University of Medical Sciences, Shiraz, Iran. The mean age of the patients at the time of surgical correction was 12.6 years ranging from 6 months to 43 years, and the duration of postoperative follow-up was between 1 and 12 years. Comparison of the strain rate between the patients with acceptable ejection fraction and the control group by tissue Doppler imaging showed significant differences between the two groups regarding the lateral wall (p<0.001), but not the septal wall of the left ventricle (p=0.65). Moreover, the strain values by the speckle tracking method revealed significant differences between the patient and the control group regarding the global strain (p=0.016) and anterior, lateral, and posterior segments of the left ventricle. Although postoperative conventional echocardiography revealed normal global left ventricular function with acceptable ejection fraction, abnormal myocardial deformation of the variable segments of the left ventricle with regional and global myocardial dysfunction were well defined by speckle tracking echocardiography.

AbstractFibromuscular dysplasia is a common vascular disease, which mainly affects the renal arteries. In this study, we report the case of a 1-day-old infant who presented with severe left ventricular dysfunction immediately after birth, and subsequently died 3 days postnatally. At autopsy, an extensive myocardial infarction of the left ventricle and the septum was found, caused by an isolated fibromuscular dysplasia of left coronary artery.

Anomalous Left Coronary

Between January 2002 and December 2012, five patients (4 female) underwent corrective surgery for anomalous left coronary artery from pulmonary artery (ALCAPA). They were older than 1 year (range, 3-56 years). One of the 2 patients younger than 10 years had presented with congestive heart failure, and the other had experienced repeated episodes of lower respiratory tract infection since childhood. Of the remaining 3 adult patients, 2 had experienced angina with effort, and 1 patient had had repeated respiratory tract infections since childhood, with mild dyspnea on effort of New York Heart Association (NYHA) class II. Three patients had the anomalous left coronary artery implanted directly into the ascending aorta via coronary-button transfer, and 2 patients underwent coronary artery bypass with obliteration of the left main ostium. Two patients underwent concomitant mitral valve repair procedures, and 1 patient underwent direct closure of a perimembranous ventricular septal defect. Four patients survived the surgery, and 1 patient died because of a persistently low cardiac output. Follow-up times ranged from 3 months to 4 years. All survivors are in NYHA class I and have left ventricular ejection fractions of 45% to 60%, with moderate (n = 1), mild (n = 1), or no (n = 2) mitral insufficiency. We conclude that a few naturally selected patients with ALCAPA do survive beyond infancy and can undergo establishment of 2 coronary systems with satisfactory results.

Abstract Objectives: Anomalous origin of the left coronary artery from the pulmonary artery is associated with high mortality if not timely surgery. We reviewed our experience with anomalous origin of the left coronary artery from the pulmonary artery to assess the preoperative variables predictive of outcome and post-operative recovery of left ventricular function. Methods: A retrospective review was conducted and collected data from patients who underwent anomalous origin of the left coronary artery from the pulmonary artery repair at our institute from April 2005 to December 2019. Left ventricular function was assessed by ejection fraction and the left ventricular end-diastolic dimension index. The outcomes of reimplantation repair were analysed. Results: A total of 30 consecutive patients underwent anomalous origin of the left coronary artery from the pulmonary artery repair, with a median age of 14.7 months (range, 1.5–59.6 months), including 14 females (46.67%). Surgery was performed with direct coronary reimplantation in 12 patients (40%) and the coronary lengthening technique in 18 (60%). Twelve patients had concomitant mitral annuloplasty. There were two in-hospital deaths (6.67%), no patients required mechanical support, and no late deaths occurred. Follow-up echocardiograms demonstrated significant improvement between the post-operative time point and the last follow-up in ejection fraction (49.43%±19.92% vs 60.21%±8.27%, p < 0.01) and in moderate or more severe mitral regurgitation (19/30 vs 5/28, p < 0.01). The left ventricular end-diastolic dimension index decreased from 101.91 ± 23.07 to 65.06 ± 12.82 (p < 0.01). Conclusions: Surgical repair of anomalous origin of the left coronary artery from the pulmonary artery has good mid-term results with low mortality and reintervention rates. The coronary lengthening technique has good operability and leads to excellent cardiac recovery. The decision to concomitantly correct mitral regurgitation should be flexible and be based on the pathological changes of the mitral valve and the degree of mitral regurgitation.
