[Surgical treatment of coronary artery to pulmonary artery fistula with a saccular aneurysm]. / Trattamento chirurgico di una grande fistola coronarica tra arteria discendente anteriore e arteria polmonare, di grosso aneurisma sacculare e di coronaropatia severa trivasale.

A 60-year-old man with hypercholesterolemia and hypertension presented with acute coronary syndrome (SCA). The ECG showed lateral ischemia (T-wave inversion in V4-V6, D1 and aVL) and echocardiography showed normal left ventricular wall motion. Coronary angiography showed critical atherosclerotic lesions in the distal part of the left circumflex artery (LCx, culprit lesion), chronic total occlusion of the right coronary artery (RCA), significant but not critical stenosis in the middle part of left anterior descending artery (LAD), and a coronary artery to pulmonary artery (PA) fistula originating from the proximal part of the LAD and emptying into the PA via a coronary saccular aneurysm (12 x 12 x 10 mm). A multidetector row computed tomography angiography (CTA) confirmed the coronary artery fistula, which was treated with surgical approach. The patient underwent aneurysmorrhaphy with CAF closure and coronary artery bypass grafting on the RCA and LCx. The postoperative course was uneventful and the patient was discharged on postoperative day 14. CTA was useful for understanding the spatial relation of the CAF and the connection with the PA.

Anomalous right coronary artery origin from pulmonary artery associated with aortic stenosis, mitral regurgitation, and Vieussens' arterial ring: a very rare association and case.

We report a very rare case of anomalous origin of the right coronary artery from the pulmonary artery associated with severe aortic stenosis, severe mitral regurgitation, and Vieussens' arterial ring (VAR). Diagnosis was made accidentally during preoperative coronary angiography and confirmed by multidetector computed tomography. Surgery was performed with aortic valve replacement, mitral valve annuloplasty, right coronary artery reimplantation into the ascending aorta, and VAR resection. .

Pheochromocytoma mimicking a non-ST elevation acute myocardial infarction.

We report a 57 year-old male patient admitted with a diagnosis of non-ST elevation acute myocardial infarction. He had suffered from chest pain, diaphoresis and intense asthenia for three days. The electrocardiogram on admission showed a high frequency sinus tachycardia. Troponin T levels were elevated. An echocardiogram suggested an antero-lateral myocardial infarction. Eventually, a left adrenal pheochromocytoma was discovered. Left ventricular function, severely depressed, returned to normal after medical and surgical therapy.

Electrocardiographic abnormalities mimicking myocardial infarction in a patient with intracranial haemorrhage: a possible pitfall for prehospital thrombolysis.

The electrocardiogram, when applied in the prehospital setting, has a significant effect on a patient with chest pain. The potential effect includes both diagnostic and therapeutic issues, including the diagnosis of acute myocardial infarction and the indication for thrombolysis or invasive procedures. We report the case of a man who suffered from a syncope, with a prehospital electrocardiogram showing prominent ST-segment elevation. Out-of-hospital thrombolytic therapy was planned by the emergency department. Fortunately, thrombolysis did not start because the patient fared worse. He was taken to the emergency department and, because of mental status impairment, it was decided to perform a cranial computed tomographic scan. The diagnosis shifted to a haemorrhagic stroke. According to the guidelines, prehospital thrombolysis would have been inappropriate in this case because the patient did not have any chest discomfort. The pathophysiological mechanisms of electrocardiographic abnormalities in the setting of intracranial haemorrhage are reviewed, as well as the issue of thrombolysis administered or planned only on the basis of an electrocardiogram.

Safety and efficacy of the percutaneous radial artery approach for coronary angiography and angioplasty in the elderly.

BACKGROUND: The transradial approach to coronary interventions has been accepted as a safe and effective alternative to the femoral approach due to fewer access site complications and improved patient comfort. In the present study we aimed to investigate the safety and efficacy of transradial procedure in the elderly. METHODS: We analyzed 850 patients who underwent transradial coronary angiography and/or angioplasty. All patients were divided into two groups, according to age. The first group consisted of patients < 70 years (600; 70.5%) and the second group consisted of patients greater than or equal to 70 years (250; 29.5%). RESULTS: Baseline characteristics did not differ between the two groups, except for diabetes mellitus which affected more patients greater than or equal to 70 years of age. Procedure duration, X-ray time and number of catheters used were similar in the two groups. No deaths or acute myocardial infarctions occurred. There were some vascular complications in both groups, with no statistically significant difference between groups. In Group 2 (the older group) 2 TIAs and 1 stroke occurred, whereas in Group 1, there was 1 TIA (p = 0.08). CONCLUSIONS: From our experience, we conclude that the transradial catheterization is a safe and effective technique in the elderly, with a reduced risk of local vascular complications and a noteworthy increase in patient comfort, especially in view of the age-related diseases that frequently affect older patients.

Successful treatment of post-exertion acute myocardial infarction by primary angioplasty and stenting in a patient with antiphospholipid antibody syndrome.

Antiphospholipid syndrome is a disorder characterized by arterial and venous thromboses, thrombocytopaenia and stroke. Acute myocardial infarction is rarely associated with this syndrome. The treatment of these patients is a clinical challenge. This report is about a patient with antiphospholipid syndrome presenting with an acute myocardial infarction after an exercise test. The infarct-related coronary artery was successfully revascularized by primary angioplasty and stenting without any major bleeding complications. We think that the physical exertion could have favoured acute coronary thrombosis in this particular setting.
