One patient with an anomalous origin of the left pulmonary artery directly from the right ventricle: a case report.

ABSTRACT:

Background

The anomalous origin of one pulmonary artery is a rare malformation, which so far has mainly been found as an anomalous origin from a different site of the aorta, accounting for 0.12% of all congenital heart diseases. This case report introduced a very rare case of the anomalous origin of one pulmonary artery which had never reported in the clinic.

Case summary

A 2-year-old boy with a 6-month history of shortness of breath and recurrent respiratory infection, was diagnosed left pulmonary artery (LPA) directly arising from the right ventricle by transthoracic echocardiography and multidetector computed tomography without a deletion in the region of 22q11. Eventually, the LPA was further conformed that arised from the right ventricle during the operation, and was corrected with a well clinical outcome.

Discussion

The surgical technique for repair of this anomalous LPA was not difficult in our case. However, the embryonic development of the present case still could not be completely explained by the current embryologic postulates since it was a new malformation that never reported. Due to its rarity, there is still much to learn about the origin and development of the pulmonary arteries that possibly develop prenatally.

Anomalous origin of left coronary artery from pulmonary artery associated with pulmonary hypertension.

Project description:This is a report on a 10-year-old child with anomalous origin of left coronary artery (LCA) from pulmonary artery (ALCAPA), severe pulmonary hypertension (PH), old myocardial infarction and poor intercoronary collateralization. It discusses the echocardiographic pitfalls in this particular setting and introduces a new echocardiographic view (posterior pulmonary cusp view) for visualization of the anomalous origin of LCA from the posterior pulmonary cusp (PC) in patients with ALCAPA from the PC of the pulmonary artery. We describe three echocardiographic pitfalls that can mislead the echocardiographer and two helpful hints that guide the clinician to the correct diagnosis. The survival of this child shows that limited size of left ventricular myocardial infarction and severe mitral regurgitation in early infancy can result in a life-saving pulmonary hypertension which preserves viability and function of left ventricle despite lack of intercoronary collateral arteries. After one year follow-up, she is doing well on medical treatment.

Very late presentation of anomalous origin of the left coronary artery from the pulmonary artery: case report.

Project description:BackgroundAnomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital coronary anomaly. The enlarged right coronary artery provides retrograde collaterals to supply the left ventricle then preferentially directs into the lower pressure pulmonary artery system causing coronary steal phenomenon. Few patients who survive through adulthood without surgery must have abundant, well-formed functioning collaterals with adequate perfusion of the left ventricle. We present the oldest reported patient with ALCAPA to undergo corrective surgery.Case presentationA 79-year-old woman presented with a 3-months history of worsening shortness of breath and orthopnea. Physical examination discovered a soft continuous murmur at the left upper chest. Transthoracic echocardiography demonstrated an unusual, tubular-like structure inside the interventricular septum with a turbulent flow from color Doppler. Moreover, there was a severe mitral regurgitation from posterior mitral leaflet restriction associated with ventricular remodeling in combination with mitral annular dilatation. Coronary angiography and coronary computed tomography angiography established the diagnostic hallmark of ALCAPA syndrome. Stress cardiovascular magnetic resonance perfusion imaging demonstrated no myocardial ischemia suggesting adequate collateral circulation. Remarkably, there was a left coronary ostial stenosis, which served as a protective mechanism against myocardia ischemia by limiting the steal effect. The patient successfully underwent the ligation of anomalous artery at its origin in combination with bioprosthetic mitral valve replacement. Her postoperative course was uneventful.ConclusionsThis case utilized multimodality imaging for delineating the course of abnormal vessels and helping to formulate therapeutic decision.

Fetal Isolated Anomalous Origin of Right Pulmonary Artery from Aorta.

Project description:The anomalous origin of a branch pulmonary artery from the aorta (AOPA) is characterized by the anomalous origin of one of the branch pulmonary arteries (PA) from the ascending aorta and a normal origin of the other PA from main PA. AOPA is an extremely rare cardiac malformation. Few studies have reported fetal anomalous origin of PA from aorta with other malformation. We report a case of isolated distal anomalous origin of the right PA from the aorta that was diagnosed by fetal echocardiography at 25 weeks' of gestation. Tracing the course of PA branches is important to make diagnosis.

Anomalous origin of the right coronary artery from pulmonary artery in an adult presenting with rapid atrial fibrillation: a case report.

Project description:BackgroundAn anomalous origin of the right coronary artery from pulmonary artery (ARCAPA) is a very rare coronary anomaly.Case summaryA 56-year-old man, presenting haemodynamically unstable due to very rapid atrial fibrillation, was found to have ARCAPA by coronary computed tomography angiography. He had normal left ventricular ejection fraction and without reversible ischaemia on an adenosine stress rubidium positron emission tomography. He was treated solely with betablockers and has been well since.DiscussionNumerous case reports on ARCAPA have previously been published, but no previous reports have found rapid atrial fibrillation to be the primary symptom of presentation. Current evidence level concerning the treatment is low; nevertheless, surgical intervention should always be considered to prevent sudden cardiac death. The patient in this case was offered surgical intervention but declined.

Sudden Cardiac Arrest in an Adult with Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery (ALCAPA): Case Report.

Project description:Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare coronary artery anomaly that carries 90% mortality in the first year of life when left untreated. The diagnosis of ALCAPA is rare in adulthood, and it includes a broad spectrum of clinical manifestations, including sudden cardiac death (SCD). We report a rare case of resuscitated sudden cardiac arrest in a 55-year-old female, who was diagnosed with ALCAPA and underwent successful surgical correction and implantable cardioverter defibrillator (ICD) implantation for secondary prevention. ALCAPA diagnosis is not confined to childhood, and it represents a rare cause of life-threatening arrhythmias and SCD in the adult population. Surgical correction is recommended, regardless of age, presence of symptoms or inducible myocardial ischemia. Multimodality imaging is crucial for diagnosis, management planning and follow up. Assessment of the risk of recurrent ventricular arrhythmias, despite full revascularization, should be performed in all adults with ALCAPA. Myocardial scar detected via late gadolinium enhancement represents a potential irreversible substrate for ventricular arrhythmias, and it provides additional information to evaluate indication of an ICD for secondary prevention.

Anomalous origin of the left coronary artery from the pulmonary artery as a rare cause of mitral valve prolapse: a case report.

Project description:BackgroundMitral valve prolapse (MVP) is an etiologically heterogeneous disorder. Early diagnosis and prompt treatment of the underlying disease are of great significance. Herein, we present a rare case of MVP caused by anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA).Case presentationA 22-year-old female presented with a 16-year history of anterior mitral leaflet prolapse. However, she had never experienced any discomfort before. At a routine follow-up, a transthoracic echocardiogram showed anterior mitral leaflet prolapse (A2) with moderate mitral regurgitation, and a retrograde blood flow from an extremely dilated left coronary artery (LCA). Further coronary angiography and coronary computed tomography angiography confirmed the diagnosis of ALCAPA. She subsequently underwent successful LCA reimplantation and concomitant mitral valve replacement. Intraoperatively, her mitral annulus was mildly dilated, anterior mitral valve leaflet appeared markedly thickened with rolled edges, and a chordae tendineae connecting the anterior leaflet (A2) was ruptured and markedly shortened.ConclusionsALCAPA is a rare and potentially life-threatening congenital coronary artery anomaly that may cause mitral valve prolapse. Echocardiogram is an important screening tool for this disorder.

Cardiogenic shock in the context of newly diagnosed anomalous origin of the right coronary artery originating from the pulmonary artery: a case report.

Project description:BackgroundAnomalous right coronary artery (RCA) from the pulmonary artery (ARCAPA) is a rare congenital heart abnormality with varying clinical presentations, for which multiple imaging modalities are often required for diagnosis.Case summaryWe present a case of a 76-year-old female presenting with 2 weeks of palpitations and shortness of breath who was found to be in rapid atrial fibrillation (AF) with congestive heart failure. Despite initial medical management, the patient developed cardiogenic shock with anuric renal failure. Emergent right and left heart catheterization did not demonstrate any significant obstructive coronary artery disease but showed severe right ventricular (RV) failure and raised the possibility of an ARCAPA. This diagnosis was further corroborated by findings on a subsequent transoesophageal echocardiogram. In view of profound decline and limited anticipated improvement, the patient ultimately decided to pursue comfort measures in a hospice setting.DiscussionWe postulate that the underlying aetiology of our patient's shock state was multifactorial, notably progressive RCA-territory ischaemia and RV failure, sepsis, and new-onset uncontrolled AF. In adults, unrecognized congenital heart disease can uncommonly cause cardiogenic shock. In our case, echocardiography and invasive angiography were integrated for the diagnosis of ARCAPA given the clinical circumstances that limited the use of cardiac computed tomography angiography.

Sudden cardiac arrest: associated with anomalous origin of the right coronary artery from the left main coronary artery.

Project description:Anomalous origin of the coronary artery from the opposite sinus of Valsalva and a course of that artery between the ascending aorta and the pulmonary artery is a rare congenital anomaly. It can cause myocardial ischemia, syncope, and sudden cardiac death in young people. Herein, we report the case of a 24-year-old man who was brought to our hospital after cardiac arrest due to ventricular fibrillation. Emergent coronary angiography revealed that the left coronary artery was normal; however, the right coronary artery originated at the left sinus of Valsalva. After admission, the patient was treated with mild therapeutic hypothermia for 48 hours and had a favorable neurologic recovery. Subsequent 16-slice multidetector computed tomography revealed that the right coronary artery arose from the left main coronary artery, took an intramural course, and was severely compressed between the ascending aorta and the pulmonary artery. The patient underwent direct implantation of the anomalous artery into the correct aortic sinus. Histologic specimens from the proximal end of the right coronary artery showed an intramural segment with intimal fibrous thickening, fragmentation and random arrangement of the elastic fiber, degeneration of the medial smooth-muscle cells, and an increase in the medial stromal substance. Postoperatively, repeat coronary angiography with provocation testing for coronary spasm revealed no myocardial ischemic change. The patient recovered uneventfully. We found that cardiac multidetector computed tomography was useful in evaluating the cause of the sudden cardiac arrest, identifying the anomalous coronary artery, and helping to guide the surgical decisions.
