Repeat mitral valve replacement in patients who underwent mechanical replacement during infancy may be technically very difficult due to the small-sized annulus accommodating the prosthesis. That can lead to dense fibrosis of the small annulus onto the sewing cuff. An attempt at explanting the prosthesis carries high risk of circumflex coronary artery injury or atrioventricular junction disruption. We present a novel approach to prevent a disaster in such a difficult scenario-implanting the new prosthesis above the previous prosthetic housing after removing the prosthetic leaflets...

Congenital absence of the left circumflex artery is a rare coronary anomaly with few reported cases in the literature. These patients are usually diagnosed incidentally when they undergo coronary angiography or coronary CT to rule out underlying coronary artery disease. In this article, we report a case of a 46-year-old man who was incidentally found to have a congenitally absent left circumflex artery with a superdominant right coronary artery after a workup was initiated for frequent premature ventricular contractions and regional wall motion on echocardiogram...

This research is a study about the arterial vascularization of pelvic cavity and pelvic limb in pampas deer. For this study, 25 dead animals were used. The vascularization of the organs was investigated using a latex injection technique. Two animals were injected in the common carotid artery with contrast to cardiac angiography, and then, radiographs were taken. The aorta showed the two external iliac arteries, and after a short course, the aorta ended in two internal iliac arteries. The median sacral artery was originated from the dorsal surface cranially to the emergence of the internal iliac arteries...

A 54-year-old man, ex smoker with high blood pressure and a history of possible Wolff-Parkinson-White syndrome was admitted for presenting an episode suggestive of acute coronary syndrome with immediate syncope and left bundle branch block, while performing physical activity. Angioplasty and a drug-eluting stent were performed in the left circumflex artery. Subsequently, Doppler echocardiography disclosed an image suggestive of a subaortic membrane. Given these findings, the patient underwent a 3D transesophageal echocardiogram and a magnetic resonance study, which confirmed the diagnosis of a subaortic membrane...

Successful raising of a distally based anterolateral thigh (dALT) flap mainly depends on a well-developed lateral circumflex femoral artery (LCFA) descending branch and an intact vascular connection between the descending branch and the vascular network of the knee. However, in some clinical scenarios, the descending branch is hypoplastic or the vascular connection of the knee is compromised. We present six cases of using dALT flaps in soft tissue defect reconstruction of the knee with either of the above-mentioned conditions...

A 4-week-old American Quarter Horse colt presented with a recent history of diarrhea and decreased activity level. On initial physical examination, the animal was bright and alert and major findings were limited to a loud systolic heart murmur radiating widely over both sides of the thorax. While in the hospital, the clinical condition of the foal warranted further imaging to determine the cause and extent of cardiac disease. A variety of congenital cardiac malformations were identified during echocardiographic examination and autopsy, including a double outlet right ventricle and a subpulmonary interventricular septal defect (Taussig-Bing anomaly), ventricular inversion with atrioventricular discordance, tricuspid valve atresia, a septum primum interatrial septal defect, mitral valve dysplasia with a cleft in the septal mitral valve cusp, aortic, and subaortic stenosis, tubular hypoplasia of the ascending aorta and the aortic arch, a patent ductus arteriosus, an aberrant circumflex coronary artery, and aberrant left and right subclavian arteries...

REVIEW
Gaetano di Palma, Bernardo Cortese
Percutaneous treatment of the unprotected left main trunk (ULM), defined as a vessel without patent bypass graft either to the left circumflex (LCX) or left anterior descending (LAD) artery, has gained a precise role thanks to recent scientific evidence. Although new generation drug-eluting stents have already proven to be safer, there is still a consistent risk of restenosis and late adverse events. The optimal management of a ULM restenosis is still debated. Here we aim at presenting a review of the available data in literature and show our choice for treating it...

The QTc interval is widely used in Safety Pharmacological studies to predict arrhythmia risk, and the electromechanical window (EMW) and short-term variability of QT intervals (STVQT) have been studied as new biomarkers for drug-induced Torsades de Pointes (TdP). However, the use of EMW and STVQT to predict ventricular fibrillation (VF) has not been elucidated. This study aimed to evaluate EMW and STVQT to predict VF in anesthetized rabbit model of VF. VF was induced by ligation of the left anterior descending and a descending branch of the left circumflex coronary arteries in a sample population of rabbits (n=18)...
