“…In children, difficulties of dietary control and blood clotting tests need close monitoring. 6,7 Typical chest pain, ischaemic electrocardiogram findings with raised cardiac enzymes in patients with mechanical valves, and acute coronary syndrome should be suspected. Echocardiography showed normal systolic functions and no wall motion abnormality.…”

Acute coronary syndrome in an adolescent with aortic root replacement (Bentall)

Acute coronary syndrome is a cause of cardiac-induced chest pain and rarely seen among childhood. It should be kept in mind in patients presenting with typical chest pain with a history of CHD and/or surgery, as this will lead to life-threatening complications and death. We present an adolescent with a history of Bentall operation who had acute coronary syndrome owing to coronary thrombosis as a result of inappropriate drug use.

“…The underlying pathologies known to cause embolic MI are: AF, tissue or mechanical valve replacement, or a large atrial septal defect (ASD). Other non-atherosclerotic causes of coronary emboli include drug abuse, coronary spasm, paradoxical embolism and rupture of sub-angiographic plaque [6].…”

ST-Elevation Myocardial Infarction in an Adolescent

Myocardial infarction (MI) in the elderly is often due to atherosclerotic accumulation, while an MI in younger patients is often due to embolic events. An embolic MI is rare, accounting for 2.9% of all MIs, but has a higher risk of morbidity and mortality. The most common causes of embolic MI are infective endocarditis, atrial fibrillation, valvular heart disease, prosthetic heart valve, and mural thrombus. We present a unique case study of an ST-elevation MI (STEMI) in an adolescent, with none of the aforementioned risk factors. Our case reports a 17-year-old Caucasian male who presented to the emergency department with substernal chest pain that started while he was watching television. The pain was severe, and radiated down his left arm and up his left neck. Social history and family history were unremarkable. Vitals were within normal limits. The telemetry did not demonstrate any abnormalities. An electrocardiogram (EKG) was performed, as a rule-out, and surprisingly demonstrated an STEMI in the anterior leads with focal ST-segment depressions in the inferior leads. Cardiac catheterization was performed that demonstrated 100% stenosis in the middle to distal left anterior descending (LAD) artery. A stent was unable to be placed due to the small caliber of the occluded vessel, and medical management was started. Transesophageal echocardiogram (TEE) later demonstrated a patent foramen ovale (PFO).

“…In patients with acute myocardial ischemia after AVR, it is important to take into consideration the ostial or proximal narrowing or occlusion of the coronary artery due to coronary artery spasm or calcium embolism related to aortic valve decalcification, thrombus, bacterial embolism or air [6,7]. In these cases, coronary artery occlusion may cause difficulties in restoring circulation after extracorporeal circulation or recurrent ventricular fibrillation.…”

Acute perioperative myocardial infarction caused by coronary artery embolization after aortic valve implantation is a rare and often fatal postoperative complication. We present a case report of a 67-year-old patient operated on for aortic valve replacement (AVR) and myocardial revascularization (LITA-LAD anastomosis). Myocardial ischemia caused by occlusion of the previously intact circumflex coronary artery occurred in the early postoperative period. Despite a successful balloon angioplasty of the closed artery in the fifth hour after the procedure, the status of the patient did not improve significantly. A decrease in progressive arterial pressure, multiple organ failure, a significant rise of myocardial necrosis markers and the lack of external pacing led to death on the second day after the operation. Acute myocardial infarction after aortic valve replacement caused by occlusion of coronary vessels by calcium debris or thrombosis is a rare postoperative complication, which may be fatal even if the patency of the vessel is promptly restored.
