A Rare Case of Left Anterior Descending Coronary Artery to Pulmonary Trunk Fistula Associated with Takotsubo Cardiomyopathy.

Project description:Coronary-artery-to-pulmonary-artery fistulae represent rare vascular anomalies defined as abnormal communications between the coronary arteries and the pulmonary arterial system. Takotsubo Syndrome represents a stress-induced cardiomyopathy defined by transient regional systolic dysfunction of the left ventricle, with minimal elevation of cardiac biomarkers, without angiographic evidence of obstructive coronary artery disease. We hereby richly illustrate an unusual and rare case of a female patient with Takotsubo Cardiomyopathy and left-anterior-descending-coronary-artery-to-pulmonary-trunk fistula through multi-modality imaging evaluations, obtaining a detailed anatomical representation of the coronary arteries and the fistulous connection, which further guided the optimal treatment strategy. The patient was treated conservatively. The main teaching points of this case are the following: (1) The coronary fistula may represent just an incidental finding in a Takotsubo Cardiomyopathy clinical scenario. (2) The particularly rare association between left-anterior-descending-coronary-artery-to-pulmonary-trunk fistula and Takotsubo Cardiomyopathy presentation is mainly due to the stress-induced overstimulation of myocardial beta-1 receptors, accentuating the coronary steal phenomenon in the setting of the coronary fistula, manifesting as anginal pain, and also the stress-induced adrenergic drive causing the Takotsubo-like presentation with apical ballooning of the left ventricle.

Left anterior descending coronary artery compressed by a giant coronary fistula aneurysm: a case report.

Project description:BackgroundIschaemic chest pain can be originated by different causes. Among all, coronary fistulas are rarely the reason. Such entities are usually asymptomatic and can be diagnosed by echocardiography or coronary angiography. In an even rarer scenario, coronary fistulas might dilate and form an aneurysm.Case summaryWe report the case of a 62-year-old patient who was initially referred to the emergency department for stable angina. Coronary angiography and computed tomography scan showed a giant aneurysm relating to a coronary fistula with a course from the circumflex coronary artery to the superior vena cava. The aneurysm was critically compressing the left anterior descending coronary artery. It was confirmed and resolved by surgery.DiscussionGiant aneurysms of a coronary fistula are very uncommon entities. We describe a rare case of angina caused by extrinsic compression of the left anterior descending artery from a giant aneurysm of a coronary fistula.

Anomalous left anterior descending artery from pulmonary artery: an extremely rare coronary anomaly.

Project description:We report a rare coronary artery anomaly-anomalous origin of the left anterior descending artery from the pulmonary artery in a 40-year-old woman. The uniqueness of this case is the absence of any significant morbidity from this condition in adulthood which is in contrast to other reported cases where patients present with myocardial infarction, congestive heart failure, and sometimes death during the early infantile period.(1).

Rare case of a giant thrombosed left anterior descending coronary artery aneurysm.

Project description:BackgroundCoronary artery aneurysms (CAAs) are rare, and giant CAAs are even rarer. The pathophysiology of this phenomenon is still unknown.Case presentationHerein, we present the case of a 49-year-old male with a giant aneurysm in the left anterior descending artery.ConclusionsThe optimal treatment for CAAs is debatable, but surgical intervention is preferred for giant CAAs.

Left anterior descending/right coronary artery bifurcation angioplasty in a rare case of single coronary artery: a case report.

Project description:BackgroundSingle coronary artery (SCA) is a rare congenital coronary anomaly with incidence of 8-66 per 100 000 cases. Percutaneous coronary intervention (PCI) in patients with SCA is technically challenging. This is a case of bifurcation angioplasty involving left anterior descending/right coronary artery (LAD/RCA) in a patient with SCA and 1-year follow-up with computed tomography coronary angiography (CTCA).Case summaryA 52-year-old female with history of PCI to LAD 4 months back, presented with non-ST-elevation myocardial infarction. Coronary angiogram showed 90% stenosis in mid-LAD, distal to the previous stent and proximal to an anomalously originating RCA from mid-LAD. She was planned for LAD/RCA provisional bifurcation angioplasty and a drug-eluting stent was deployed in LAD across RCA, following which patient developed angina with ischaemic electrocardiogram (ECG) changes due to significant pinching of RCA. Using Reverse crush technique, RCA was stented successfully with resolution of angina and ECG changes. At 1-year follow-up, patient is in New York Heart Association class I with normal left ventricular function and patent LAD/RCA bifurcation stent on CTCA.DiscussionSCA poses a great challenge to interventional cardiologists during PCI, especially in the event of a complication. Detailed anatomical knowledge, appropriate hardware and operator expertise are the key factors for successful PCI of SCA. This is, to the best of our knowledge, the first case report of bifurcation angioplasty of LAD/RCA in a rare case of SCA. This case also describes the use of reverse crush technique as a bailout strategy during provisional bifurcation angioplasty.

Predicting severe proximal left anterior descending coronary artery stenosis using proximal left anterior descending coronary artery tortuosity and the angle between the left main and anterior descending coronary arteries: a retrospective cross-sectional study.

Project description:Coronary bifurcation angles influence plaque initiation in the coronary artery, and changes in blood flow caused by tortuosity in the coronary arteries can reduce blood pressure distal to the tortuous portion of the coronary artery, leading to myocardial ischemia. We aimed to describe two factors (coronary artery tortuosity and bifurcation angle) as one descriptor for the evaluation of proximal left anterior descending coronary artery (LAD) disease. We reviewed the medical records of 133 consecutive patients who underwent computed tomography angiography (CTA) for angina symptoms between November 2019 and January 2020. The patients were divided into two groups according to the presence of significant LAD stenosis on CTA (defined as LAD stenosis >50%). The straight length of the vessel was measured using the central luminal line of the flow path, and, calculated using proprietary algorithms in TeraRecon software. We used three-dimensional volume rendering and two-dimensional axial images to measure the left main coronary artery (LM)-LAD angles. In the univariate analysis, there were significant differences in the linear distance between the endpoints of the 20 mm actual curve of the LAD (d20), cosine value for LM-LAD angle (cosθ) <0.8, age, presence of hypertension or diabetes, and number of pack years [hazard ratio (HR): 2.70, 8.04, 1.05, 3.70, 2.82, and 1.04; P=0.029, P<0.001, P=0.020, P=0.024, P=0.021, and P=0.002, respectively]. However, in the multivariate analysis, the cosθ multiplied by d20 (d20*cosθ) <15.5, presence of hypertension and number of pack years (HR: 11.36, 4.54, and 1.04; P<0.001, P=0.019, and P=0.003, respectively) were predictors of significant proximal LAD stenosis. As the tortuosity and LM-LAD angle increased (d20 and cosθ decreased, respectively), the chance of proximal LAD lesions formation increased. d20*cosθ might be useful as a predictor of proximal LAD stenosis.

Atypical type of dual left anterior descending coronary artery.

Project description:Dual left anterior descending coronary artery (LAD) is a rare coronary anomaly and is divided into six subgroups in the literature according to the origin and course of the short and long branches of the anomalous artery. We present two distinct cases of dual LAD which are distinguished by two branches of equal length from their counterparts in the literature. <Learning objective: In our cases a novel dual LAD variant is presented with two main branches of equal length and reaches the cardiac apex. Cardiologists and cardiovascular surgeons should be aware of these variants to avoid misinterpretation of coronary angiography and intraoperative complications.>.
