BACKGROUND: Pulmonary artery aneurysm (PAA) occurs in some patients with pulmonary arterial hypertension (PAH). We evaluated the characteristics of cardiac dysfunction in patients with PAH complicated by PAA. METHODS: Echocardiography and right-heart catheterization were performed in 130 PAH patients to measure the maximum dimensions of the main pulmonary artery (MPA) trunk and evaluate right ventricular (RV) and left ventricular (LV) function. RESULTS: A diameter of >40mm was defined as PAA in the MPA trunk...

Spontaneous coronary artery dissection is a rare cause of acute coronary syndrome and sudden cardiac death. We report coronary artery dissection in a 36-year-old woman with retrosternal chest pain 2 weeks after abortion. Electrocardiography showed ST elevation in leads V2-V4 and ST depression in the inferior leads. Lab data were normal. Cardiac catheterization showed a suspicious thrombotic lesion at the proximal portion of the left anterior descending artery with a smooth contour consistent with distal haziness and dissection site...

BACKGROUNDS: ST-elevation myocardial infarction (STEMI) guidelines recommend reperfusion by primary percutaneous coronary intervention (PCI) ≤ 90 min from time of first medical contact (FMC). This strategy is challenging in rural areas lacking a nearby PCI-capable hospital. Recommended reperfusion times can be achieved for STEMI patients presenting in rural areas without a nearby PCI-capable hospital by ground transportation to a central PCI-capable hospital by use of protocol-driven emergency medical service (EMS) STEMI field triage protocol...

BACKGROUND: Patients with severe familial hypercholesterolemia (FH) are often unrecognized despite typical presentation. The introduction of PCSK9 inhibitors opens new therapeutic options and emphasizes the need for identification of severe FH patients. OBJECTIVES: The objective was identification, characterization, and management of severe FH patients by screening of cardiac catheterization (CC) database. METHODS: Retrospective analysis of CC database from 2002 to mid-2015 was performed for low-density lipoprotein cholesterol (LDL-C) ≥130 mg/dL (n = 2383)...

Brian D Hoit
Pericardial heart disease includes pericarditis, (an acute, subacute, or chronic fibrinous, noneffusive, or exudative process), and its complications, constriction, (an acute, subacute, or chronic adhesive or fibrocalcific response), and cardiac tamponade. The pathophysiology of cardiac tamponade and constrictive pericarditis readily explains their respective findings on clinical examination, Doppler echocardiography, and at cardiac catheterization. The primary abnormality of cardiac tamponade is pan-cyclic compression of the cardiac chambers by increased pericardial fluid requiring that cardiac chambers compete for a fixed intrapericardial volume...

AIMS: Non-fluoroscopic catheter ablation is becoming routine. In experienced centres, fluoroscopy is rarely required. The use of a traditional catheterization lab (cath lab) may no longer be necessary. We began performing catheter ablations at a paediatric centre outside the traditional cardiac cath lab in 2013. The purpose of this study was to compare procedural features of paediatric catheter ablation performed outside the cath lab to those performed within a cath lab. METHODS AND RESULTS: We prospectively looked at patients presenting to the paediatric centre with supraventricular tachycardia (SVT) undergoing catheter ablation outside the cath lab in a standard operating room (OR group)...

BACKGROUND: Cardiac magnetic resonance (CMR) has promise of being able to provide frequent cardiac morphology and function evaluations noninvasively for repeated follow-ups of pulmonary arterial hypertension (PAH) patients after the initial right heart catheterization (RHC) diagnosis. By using the noninvasive CMR indices, the present study aimed to formulate and validate a prediction model of mean pulmonary artery pressure (mPAP) and pulmonary vascular resistance (PVR). METHODS: Both Derivation Cohort (N=25) and Validation Cohort (N=25) of PAH patients underwent CMR and RHC within one week...

BACKGROUND: RV dyssynchrony has been described in patients with pulmonary hypertension (PH) and is an independent predictor of clinical worsening; however, the optimal method for measuring RV dyssynchrony has not been fully established. This study aimed to investigate whether RV dyssynchrony is correlated with hemodynamics and prognosis in PH patients and to identify the best parameter for evaluating RV dyssynchrony. METHODS: This study assessed 100 PH patients, measuring mean pulmonary artery pressure (mPAP), pulmonary vascular resistance (PVR), and cardiac index (CI) by right heart catheterization (RHC)...

BACKGROUND: Accurate assessment of cardiac output (CO) is essential for the hemodynamic assessment of aortic valve area (AVA). Estimation of oxygen consumption (VO2) and Thermodilution (TD) is employed in many cardiac catheterization laboratories (CCL) given the historically cumbersome nature of direct continuous VO2 measurement, the "gold standard" for this technique. A portable facemask device simplifies the direct continuous measurement of VO2, allowing for relatively rapid and continuous assessment of CO and AVA...

BACKGROUND: Accurate assessment of Cardiac Output (CO) is a critical measurement in the calculation of aortic valve area (AVA). Due to the known inaccuracy of estimated Fick calculations, many measure thermodilution (TD) CO as well due to previous studies showing better correlation with the gold standard direct CO. Previous studies showed suboptimal correlation between both methods. Most physicians assume that the TD CO is chosen by catheterization laboratory software for AVA evaluation...

BACKGROUND: Unsuccessful radial artery puncture is one of the important causes of transradial procedure failure. Ulnar artery compression made the radial artery pulse stronger. Whether it would make transradial access easier, however, is uncertain. METHODS: A prospective randomized controlled trial was conducted among 446 patients who planned for transradial cardiac catheterization. Patients were randomized to receiving either transient ulnar artery compression (UC) or standard treatment (standard) for half an hour prior to needle insertion (217 UC, 229 standard)...

BACKGROUND: Right ventricular (RV) function is an independent predictor of clinical outcomes in patients with pulmonary arterial hypertension (PAH). However, it remains controversial which RV parameter should be measured as an appropriate index for the treatment of PAH. The aim of this study was to identify the most useful parameter that correlates with hemodynamics and predicts clinical outcomes in PAH. RESULTS: Most of the clinical and echocardiographic RV parameters were significantly correlated with pulmonary vascular resistance (PVR) as well as mean pulmonary arterial pressure (mPAP)...

Idiopathic dilatation of pulmonary arteries (IDPA) is a rare abnormality of pulmonary arteries, the reported incidence in literature being as low as 0.007% in autopsy samples. With the improvement in diagnostic modalities, antemortem diagnosis of IDPA has been increasingly established by excluding diseases that induce pulmonary arterial enlargement. Here, we present a rare case of idiopathic dilatation of the pulmonary artery admitted with shortness of breath where IDPA was diagnosed as an incidental finding using computed tomography pulmonary angiography and cardiac catheterization...

We report a massive infected pseudoaneurysm of the right external iliac artery in the setting of Girdlestone pseudoarthroplasty (GSA) for chronic infection. Around the time of her GSA the patient underwent cardiac catheterization with resultant pseudoaneurysm formation. Infection was likely due to spread from her previous chronic infection. Delay in presentation occurred due to attribution of her symptoms to her GSA. The patient underwent ligation of the right external iliac artery and hip disarticulation and was discharged on antibiotics...
