A 61-year old female presented with cardiac arrest. The diagnostic process following successful cardiopulmonary resuscitation was consistent with a left anterior descending to pulmonary artery fistula (Figs. 1 and 2). The patient underwent surgical ligation of the fistula, under cardiopul-monary bypass without complications. Fig. 1. Coronary angiogram showing fistulous vessel (arrow) from the l...
We present an interesting but high-risk case of an obese male patient aged 56 years with dextrocardia and a left diaphragmatic hernia. Anterior myocardial infarction was diagnosed in 1994, and the patient later presented with a history of unstable angina. The diagnosis for this chronic smoker was triple-vessel disease, impaired left ventricular function, chronic renal failure, chronic bronchiti...
Coronary artery anomalies are a rare type of congenital anomalies with an incidence of 1.3% during routine cardiac catheterization. Anomalous origin of the coronary arteries is considered an incidental finding without clinical significance. This case describes a patient in whom evaluation of chest pain revealed an obstructive left anterior descending artery as well as an anomalous right coronar...
Eighteen months after graft surgery to the posterior descending, circumflex, and left anterior descending coronary arteries, it seems that blunt chest trauma caused by a car accident resulted in occlusion of the grafts.
Coronary stent loss is a rare but serious complication during interventional cardiology. This complication occurs not only in the intracoronary area but also in the extracoronary area, such as the aortic root or the left ventricle. An 83-year-old man with stable angina had a stent inserted into a heavy calcific left anterior descending artery. The stent was lost twice during the procedure. The ...
We present the time course of transthoracic coronary flow reserve in the left anterior descending artery in a patient who suffered a transient left apical ballooning syndrome.
A 68-year-old woman exhibited an increasingly protruding mass on the left heart border on chest X-ray. Transthoracic echocardiography revealed an echo-free mass in the anterior pericardial space. Transesophageal echocardiography revealed blood flow from the proximal left anterior descending coronary into a large coronary artery aneurysm measuring 61 mm × 51 mm in diameter and a quadricuspid aor...
Polymorphism of water has been extensively studied, but controversy still exists over the phase transition between high-density amorphous (HDA) and low-density amorphous (LDA) ice. We report the phase behavior of HDA ice inside high-pressure cryocooled protein crystals. Using X-ray diffraction, we demonstrate that the intermediate states in the temperature range from 80 to 170 K can be reconstr...
