PURPOSE: Coronary-pulmonary arterial fistulas (CPAFs) are rare coronary artery anomalies that have been described only in limited case reports. This study aims to evaluate the clinical presentation and imaging findings of CPAFs collected from 6 participating medical centers along with CPAFs reported in the literature, to discern any general trends present in CPAFs. MATERIALS AND METHODS: A total of 25 cases of CPAF diagnosed by coronary computed tomography angiography were collected across 6 participating institutions...

Current Hypertension Guidelines emphasize the importance of assessing the presence of preclinical organ damage. In fact, an extensive evaluation of organ damage may increase the number of patients classified at high CV risk and therefore strongly influence the clinical management of patients. Hypertensive heart disease remains to date the form of organ damage for which there is the greatest amount of evidence of a strong independent prognostic significance. In the presence of a chronic pressure overload, a parallel addition of sarcomers takes place with an increase in myocyte width, which in turn increases left ventricular wall thickness; myocyte hypertrophy is also associated with apoptosis, collagen deposition and ventricular fibrosis with an impairment of coronary hemodynamics as well, thus profoundly influencing functional properties of the left (and right) ventricle...

Chronic hypertension can result in deleterious effects on various vascular organs including the heart and vessels. Cardiovascular magnetic resonance (CMR) has the unique advantage of the ability to assess ventricular volumes and function, valvular abnormalities, vascular pathology, myocardial perfusion and tissue characterization with high accuracy and reproducibility and also avoid the risk of radiation. As this is the case, CMR seems to be an ideal method for comprehensive assessment of patients with systemic hypertension...

A 48-year-old man presented with chronic right sided heart failure. 2D echocardiography revealed the classical features of left ventricular endomyocardial fibrosis with a prominent right ventricular apical aneurysm. Right ventriculography further defined the aneurysm. Cardiac magnetic resonance images revealed a thin-walled, apical aneurysm of right ventricle with multiple septations and marked obliteration of left ventricular apex. A delayed-enhancement sequence after the infusion of contrast, demonstrated a hypersignal in the subendocardium, consistent with the right ventricular involvement of endomyocardial fibrosis...

Parachute mitral valve and Pacman heart (incomplete muscular ventricular septal defect) are rare congenital deformities usually reported in infants and children. Very few adult patients with these anomalies are reported but the association of the two has not been described. This report describes a 56-year-old male with exertional dyspnea who was detected to have moderately severe mitral regurgitation and mitral stenosis. Typical parachute deformity of the mitral valve with a reduced opening and common attachment of all the chordae to a single posteromedial papillary muscle was evident...

BACKGROUND: Risk of delayed cerebral ischemia (DCI) in aneurysmal subarachnoid hemorrhage (aSAH) patients with asymptomatic angiographic vasospasm on admission is unclear in the literature. The goal of this study is to identify predictors of clinical DCI in this group of patients. METHOD: ology: An exploratory subgroup analysis was conducted in the Subarachnoid Hemorrhage International Trialists (SAHIT) data repository to identify predictors of clinical DCI in good-grade aSAH patients (World Federation of Neurological Surgeons (WFNS) grade I and II) with angiographic vasospasm on admission...

We experienced a rare case of post-infarct left ventricular aneurysm (LVA) and ventricular septal perforation (VSP). An 83-year-old woman was treated for acute cardiac insufficiency. Three weeks later after hospitalization, she had sudden cardiorespiratory failure and was diagnosed with VSP and LVA. She underwent emergency heart surgery. After establishing extracorporeal circulation, the LVA was excised longitudinally from the left side of the left anterior descending branch. Endoventricular patch plasty (Dor procedure) was performed to exclude the ventricular aneurysm, and the VSP was closed using Dacron patch...

Left ventricular aneurysm (LVA) and false aneurysm are complications of acute myocardial infarction, trauma, and cardiac surgery. Left ventricular false aneurysm (LVFA) is a particularly catastrophic complication owing to its high propensity for rupture. Surgical resection should be considered for LVFA occurring within three months after myocardial infarction or development of congestive heart failure. In this report, we describe a case of acute heart failure with LVA and LVFA occurring in stage as a complication of myocardial infarction in a 55-year-old man...

A 13-year-old female Persian cat died suddenly after severe respiratory distress. At necropsy, the changes were compatible with congestive heart failure. The heart was enlarged with a flabby and puckered sac-like aneurysm at the apex of the left ventricle. The apical zone showed a thin muscular wall arising from the free wall of the left ventricle connected to a bulged saccular area through a wide communication. Microscopically, the wall of the aneurysm was composed of fibrous connective tissue with neovascularization and sparse atrophied myocardial cells at the margins...

A 54-year-old woman was hospitalized for an acute pulmonary oedema revealing a severe aortic stenosis (AS) associated with an aortic aneurysm and a left ventricular hypertrophy (LVH). The coronary angiography found an equivocal left main lesion. Fractional flow reserve (FFR) showed hemodynamic significance (FFR=0.78) and optical coherence tomography confirmed this result with a minimal lumen area of 4.9mm(2). FFR-guided percutaneous intervention is reported to improve outcome in patients with stable coronary disease...

Complications of valvular infective endocarditis involving the peri-annular region puts the patient at a significantly high risk of adverse outcomes including heart failure and death. The "mitral-aortic intervalvular fibrosa" is relatively avascular and offers little resistance to the spread of abscesses, aneurysm, and fistula formation. Aorto-cavitary fistulous tract formation in the setting of native valve infective endocarditis is associated with higher rates of heart failure, ventricular septal defect, and atrioventricular block than nonruptured abscesses...

CLINICAL INTRODUCTION: A 50-year-old hypertensive smoker presented with a typical angina of 2 days duration. An urgent ECG revealed extensive anterior wall myocardial infarction. In view of the delayed presentation, the patient was conservatively managed with heparin. In-hospital echocardiogram showed akinesia of entire left anterior descending artery (LAD) territory with severe left ventricular (LV) dysfunction. He was discharged with a plan for early coronary intervention. However, he presented a fortnight later with acute pulmonary oedema...

OBJECTIVES: Dye-mediated photo-oxidation of pericardium is an alternative method to chemical treatment with glutaraldehyde for cross-linking collagen, providing biostability of the patch material while avoiding late calcification and cytotoxicity. There are few data available, on using photo-oxidation-treated pericardium, in congenital cardiac surgery. This study reports the outcomes using Photofix™ bovine pericardium in neonates, infants, children and young adults undergoing paediatric cardiac surgery...

Treatment of congenital heart defects in children requiring right ventricular outflow tract reconstruction typically involves multiple open-heart surgeries because all existing graft materials have no growth potential. Here we present an 'off-the-shelf' vascular graft grown from donor fibroblasts in a fibrin gel to address this critical unmet need. In a proof-of-concept study, the decellularized grafts are implanted as a pulmonary artery replacement in three young lambs and evaluated to adulthood. Longitudinal ultrasounds document dimensional growth of the grafts...

BACKGROUND: In patients with poor clinical condition after aneurysmal subarachnoid haemorrhage (aSAH), treatment is often deferred until patients show signs of improvement. Early external ventricular drainage and aneurysm occlusion may improve prognosis also in poor grade patients. The clinical outcome of an expeditious approach was compared with that of a conservative approach. METHODS: In all, 285 consecutive World Federation of Neurological Surgeons (WFNS) grade V aSAH patients admitted to three university hospitals between January 2000 and June 2007 were included...

INTRODUCTION: Kawasaki disease (KD) is an acute vasculitis of unknown origin and predominant in males. The long-term effects of the disease depend on whether there are coronary lesions, particularly aneurysms. The prognosis of patients with giant aneurysms is very poor due to their natural progression to coronary thrombosis or severe obstructive lesions. OBJECTIVES: A series of 8 cases is presented where the epidemiology and diagnostic methods are described. The treatment of the acute and long-term cardiovascular sequelae is also reviewed...
