Anomalous origin of left coronary artery from pulmonary artery (ALCAPA) accounts for 0.4% of the congenital heart diseases. Comprehensive 2D and 3D transesophageal echocardiographic imaging of a well-collateralized subset of ALCAPA is described. A nonstandard short-axis view of both aorta and pulmonary arteries showed the origin of left coronary artery from the posterior sinus of the pulmonary artery and right coronary artery in its usual position. Pulse-wave interrogation of the coronary arteries showed the direction of flow in opposite directions...

Spontaneous coronary artery dissection (SCAD) is still today an underdiagnosed disease due to the absence of angiographic hallmarks in more than 70% of cases. In several cases, an intravascular imaging is a sole tool for recognizing a dissection. Particularly, optical coherence tomography analysis (OCT) could represent the gold standard technique of easy interpretation and prompt diagnosis. Here we present a rare case of multivessel spontaneous coronary artery disease (SCAD) with atypical collateral circulation...

BACKGROUND: There is little evidence on how to select an interventional collateral channel (CC) in retrograde chronic total occlusion (CTO) percutaneous coronary intervention. We aimed to identify independent angiographic predictors of CC tracking and technical success in retrograde CTO percutaneous coronary intervention. METHODS AND RESULTS: From January 2012 to December 2015, a total of 216 consecutive retrograde CTO percutaneous coronary intervention attempts by a high-volume operator in a tertiary university-affiliated hospital were enrolled...

For identification of myocardial ischaemia by non-invasive imaging or invasive physiological assessment, administration of a vasodilating or positive inotropic agent is often considered indispensable to exhaust the cardiac compensation mechanisms. Indeed, microcirculatory dilatation is needed for assessment of myocardial perfusion or coronary blood flow. However, three different modalities exist that quantify myocardial ischaemia without recourse to pharmacological stress agents, using either myocardial contrast echocardiography, imaging of myocardial blood volume or invasive coronary pressure measurement with the instantaneous wave-free ratio (iFR)...

BACKGROUND: Dual left anterior descending (LAD) artery or duplication of LAD is a rarely reported coronary anomaly, consisting of two branches supplying the usual distribution of the LAD. Type IV dual LAD, in which a short LAD arises from the left main coronary artery and a long LAD arises from the right coronary artery is remarkably rare, and has not been reported in a Bangladeshi subject. CASE PRESENTATION: We describe the case of a 70-year old Bangladeshi male who presented with breathlessness in the background of a prior inferior myocardial infarction...

Adults with anomalous left coronary artery from the pulmonary artery (ALCAPA) typically have multiple venous and arterial collateral arteries surrounding the artery, making precise ligation imperative. Most physicians delay mitral valve repair until left ventricular function improves. The objective is to achieve reperfusion through a 2-coronary system reimplanting the ALCAPA into the aorta.

An aorta-to-right atrium (RA) fistula is an anomalous communication between the ascending or descending thoracic aorta and the RA. In this report, we describe a case of an idiopathic aortic root-to-RA fistula occasionally found during a coronary angiography performed in a young patient admitted for acute chest pain with evidence of multivessel coronary artery disease. The anatomical peculiarity of this fistulous communication is that it gave origin to collateral vessels furnishing the inferolateral wall of the left ventricle...

Although the hybrid chronic total occlusion (CTO) algorithm had many excellent recommendations, there has been infrequent adoption in the Asia Pacific region. The Asia Pacific CTO club propose an algorithm for case selection based on the Japan-CTO score and a new CTO algorithm, which is applicable globally. This algorithm allows for differing skill sets and equipment availability and contains practical teaching for CTO percutaneous coronary intervention. Similar to the hybrid algorithm there are 3 main questions that determine whether the primary approach is antegrade or retrograde: 1) is there proximal cap ambiguity; 2) is the distal vessel of poor quality; and 3) are there interventional collaterals present...

Retroperitoneal hemorrhage from iliac artery injury is a potentially serious complication of vascular interventional procedures leading to hemorrhagic shock and death if not diagnosed early and treated promptly. We report a 70-year-old male admitted to our facility with non-ST-elevation myocardial infarction, whose heart catheterization revealed left anterior descending artery (LAD) with 80% proximal, 95% mid and 100% distal disease. The left circumflex and right coronary arteries were 100% occluded proximally and received collaterals from the LAD...

Background/Aims: Contrast-induced nephropathy (CIN) is a typically reversible type of acute renal failure that develops after exposure to contrast agents; underlying endothelial dysfunction is thought to be an important risk factor for CIN. Although the mechanism of coronary collateral circulation (CCC) is not fully understood, a pivotal role of the endothelium has been reported in many studies. The aim of this study was to investigate whether there is a relationship between CCC and CIN...

BACKGROUND: For patients with severe ischemic heart disease, complete revascularization by a percutaneous coronary intervention or coronary artery bypass grafting is often not achieved and may still cause residual angina. In case of progressive coronary artery occlusions, therapeutic arteriogenesis constitutes a promising strategy for increasing blood supply to the ischemic myocardium. Whether the formation of collaterals in the hypofused myocardium is angiogenetic in nature or based on preformed coronary artery anastomoses remains debatable...

The anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital anomaly. The usual clinical course is severe left-sided heart failure and mitral valve insufficiency presenting during the first months of life. However, in some cases, the collateral blood supply from the right coronary artery is sufficient and symptoms may be subtle or even absent. We describe a 49-year-old woman presenting with atypical chest pain during physical exertion. The exercise tolerance test and then coronary angiography by indication revealed an anomalous origin of the left coronary artery...

Among 241 children with univentricular circulation who underwent total cavopulmonary connection (Glenn or Fontan) over a 17 years period (January 2000-April 2017), we found two patients who had diffuse coronary fistulisation of their myocardium (0.8%). We also report an additional third case from Oak Lawn, Illinois, USA. One of the children had documented normal coronary arteries and myocardium at catheterisation prior to development of the fistulisation process. The same child also developed extensive veno-venous collaterals...
