Project description:Although spontaneous coronary artery dissection (SCAD) is usually diagnosed by coronary angiography, diagnosis may be missed because of various presentations and imperfections of coronary angiography. We report a case of a 41-year-old female with pregnancy-related SCAD who presented with cardiac arrest. Initial coronary angiography was normal without intimal flap. Unexpectedly, 4 days after admission, SCAD in left main trunk was revealed with recurrent myocardial infarction. Intimal flap was sealed at the time of first angiography and this is an interesting point that made us report this case. SCAD is a rare but not negligible cause of not only acute myocardial infarction but also sudden cardiac arrest even if first coronary angiography is normal. <Learning objective: In a case of a young post-partum woman with resuscitated sudden cardiac arrest who has normal coronary artery, intensive observation is needed. We should be aware that spontaneous coronary artery dissection is a rare but not negligible cause even if initial coronary angiography is normal.>.

Percutaneous coronary intervention for iatrogenic coronary artery pseudoaneurysm at left main trunk bifurcation: A case report.

Project description:A 70-year-old man was referred to our hospital with a diagnosis of progressive increase in extravasation leading to an iatrogenic coronary artery (CA) pseudoaneurysm within a month of percutaneous coronary intervention (PCI). The pseudoaneurysm was located on the carina side of the proximal left descending artery (LAD) accompanied by peri-stent contrast staining around the left main trunk (LMT). After a shared decision-making process, a second PCI was performed to prevent CA pseudoaneurysm rupture owing to concerns of adhesion around the LMT and difficulty in approaching the carina side of the proximal LAD for surgery. Coil embolization with four coils was performed and kissing stents with two covered stents were implanted. After the "Double-D molding technique," intravascular ultrasound imaging revealed only small residual spaces out of the stents. Final coronary angiography (CAG) revealed no contrast staining of the pseudoaneurysm. Four months after the PCI, follow-up CAG revealed no further pseudoaneurysm enlargement. To the best of our knowledge, this is the first case of PCI for a CA pseudoaneurysm at the LMT bifurcation treated using kissing stents with two covered stents.Learning objectiveCoil embolization and implantation of kissing stents with two covered stents with the "Double-D molding technique" is an optional method to stop further enlargement of the pseudoaneurysm at the left main trunk bifurcation.

Spontaneous Coronary Artery Dissection Complicated by Left Ventricular Free Wall Rupture in Turner Syndrome

Project description:A 38-year-old with Turner syndrome presented with acute myocardial infarction due to multivessel spontaneous coronary artery dissection (SCAD) complicated by left ventricular free wall rupture. Conservative management for SCAD was pursued. She underwent sutureless repair for an oozing-type left ventricular free wall rupture. SCAD has not been previously reported in Turner syndrome.

Giant Left Main Coronary Artery Aneurysm: A Decade-Long Evolution of an Incidental Finding.

Project description:This clinical vignette details a rare case of a patient with a left ventricular aneurysm and an incidentally discovered giant left main coronary artery aneurysm. A review of the patient's history and previous imaging revealed the aneurysmal dilation had been present for 10 years. Giant coronary artery aneurysms are rare and typically asymptomatic, with unclear pathophysiology and poorly documented natural history. There is no consensus on the optimal intervention, underscoring the need for awareness of this rare pathology for early detection and prevention of future complications.

Left main coronary artery compression by a dilated main pulmonary artery and left coronary sinus of Valsalva aneurysm in a patient with heritable pulmonary arterial hypertension and FLNA mutation.

Project description:Left main coronary artery (LMCA) disease due to external compression by a dilated main pulmonary artery (MPA) is an uncommon clinical entity. Here, we describe a 52-year-old woman with pulmonary arterial hypertension (PAH) and anteroseptal old myocardial infarction (OMI). The cause of the OMI was external compression of the LMCA by the dilated MPA and aneurysm of the left coronary sinus of Valsalva. The patient's sister (aged 56 years) had also been diagnosed with PAH and both women had a novel heterozygous splicing mutation, IVS2-2A > G (c.374-2A > G in NM_001456), in the filamin A ( FLNA) gene. To our knowledge, this is the first report of HPAH which is likely to be due to FLNA mutation and compression of the LMCA between a dilated MPA and aneurysm of the left coronary sinus of Valsalva.

Pulmonary artery from the left main coronary artery.

Project description:The usual sources of pulmonary blood flow in pulmonary atresia (PA) with(VSD) are patent ductus arteriosus and aortopulmonary collaterals. However, rarely fistulous collaterals may also arise from the coronary arteries which usually open into the main pulmonary trunk or branch pulmonary arteries. In such cases, selective coronary angiogram may be required for the demonstration of pulmonary arterial anatomy. A case of PA with VSD with failure to demonstrate pulmonary arteries on routine catheterization study (ventricular, aortic root, and descending aortic angiograms) is being presented here. A coronary artery-to-pulmonary artery fistula was suspected in view of dilated left main coronary artery, and pulmonary arteries were well demonstrated with selective coronary angiogram.
