“…In contrast, in IPAH and PVOD, perfusion scans typically show non-segmental defects or are normal [377]. More recent work suggests that both V/Q scanning and modern CT pulmonary angiography may be accurate methods for the detection of CTEPH, with excellent diagnostic efficacy in expert hands (100% sensitivity, 93.7% specificity and 96.5% accuracy for V/Q and 96.1%, 95.2% and 95.6%, respectively, for CT pulmonary angiography) [93,423,424].…”

Guidelines summarize and evaluate all available evidence on a particular issue at the time of the writing process, with the aim of assisting health professionals in selecting the best management strategies for an individual patient with a given condition, taking into account the impact on outcome, as well as the risk–benefit ratio of particular diagnostic or therapeutic means. Guidelines and recommendations should help health professionals to make decisions in their daily practice. However, the final decisions concerning an individual patient must be made by the responsible health professional(s) in consultation with the patient and caregiver as appropriate.

“…Digital-subtraction pulmonary angiography is the most common imaging method used to examine the pulmonary vasculature and to determine patient operability [56]. Figure 3 shows selective angiograms and digital-subtraction angiograms from a 76-year-old female with CTEPH manifesting at the level of segmental and subsegmental branching.…”

Balloon pulmonary angioplasty in chronic thromboembolic pulmonary hypertension

et al. 2017

Chronic thromboembolic pulmonary hypertension (CTEPH) is thought to result from incomplete resolution of pulmonary thromboemboli that undergo organisation into fibrous tissue within pulmonary arterial branches, filling pulmonary arterial lumina with collagenous obstructions. The treatment of choice is pulmonary endarterectomy (PEA) in CTEPH centres, which has low post-operative mortality and good long-term survival. For patients ineligible for PEA or who have recurrent or persistent pulmonary hypertension after surgery, medical treatment with riociguat is beneficial. In addition, percutaneous balloon pulmonary angioplasty (BPA) is an emerging option, and promises haemodynamic and functional benefits for inoperable patients. In contrast to conventional angioplasty, BPA with undersized balloons over guide wires exclusively breaks intraluminal webs and bands, without dissecting medial vessel layers, and repeat sessions are generally required. Observational studies report that BPA improves haemodynamics, symptoms and functional capacity in patients with CTEPH, but controlled trials with long-term follow-up are needed. Complications include haemoptysis, wire injury, vessel dissection, vessel rupture, reperfusion pulmonary oedema, pulmonary parenchymal bleeding and haemorrhagic pleural effusions. This review summarises the available evidence for BPA, patient selection, recent technical refinements and periprocedural imaging, and discusses the potential future role of BPA in the management of CTEPH.

“…18,19 Basic assessment of the cardiopulmonary unit by echocardiography involves assessment of cardiac chamber size; metrics of RV function such as tricuspid annular plane systolic excursion, fractional area change, and myocardial performance indexes; valvular regurgitation or function; pulmonary hemodynamics; and septal curvature, which can integrate metrics on ventricular interdependence. 16,20,21 Table 2 summarizes normative values for the measures of function of the right side of the heart, and Figure 2 illustrates some of these measures.…”

Noninvasive Imaging in the Assessment of the Cardiopulmonary Vascular Unit

899N oninvasive imaging plays a key role in both the diagnosis and management of patients with pulmonary hypertension (PH). In recent years, there have been 2 major changes in perspective of imaging in PH. The first was the realization that imaging should focus on the evaluation of not only the pulmonary pressures but also the cardiopulmonary unit ( Figure 1). 1,2The second was the emergence of multimodality imaging with a complementary role for echocardiography, magnetic resonance (MRI), computed tomography, and positron emission tomography (PET).2-7 These techniques not only help in the diagnosis of PH but also help identify factors that determine risk and prognosis and gauge therapeutic effects on right ventricular (RV) function in patients with pulmonary arterial hypertension (PAH). Although echocardiography is the mainstay in the assessment of hemodynamic and ventricular function in PH, MRI has emerged as the gold standard for quantifying volumes, function, and flow in the right side of the heart. 2-7 PET is also offering novel insights into perfusion and blood flow, metabolism, neurohormonal activation, and other molecular processes in the right side of the heart but is used mainly for research at this time. Catheterization of the right side of the heart remains the gold standard for defining PH and assessing hemodynamics both at rest and with exercise. Invasive assessment of cardiac output (CO) may, however, have limited accuracy when assumed instead of measured oxygen consumption is used to derive CO (eg, using the Fick method) or when thermodilution is used in the setting of a low-CO state. [8][9][10] This review covers RV imaging studies performed in the field of PH and discusses recent advances in echocardiography and cardiac MRI and PET imaging for detailed assessment of RV function. The review starts with a discussion of important physiological considerations and unmet needs in imaging research of the right side of the heart in PH. Computed tomography angiography, which plays an important role in evaluating chronic thromboembolic PH, is not discussed extensively in this review. Physiological ConsiderationsAlthough PH is a syndrome affecting the pulmonary vasculature, survival of patients with PH is closely related to RV function. 1,[11][12][13][14] The RV initially adapts to the increased afterload by increasing its wall thickness and contractility. These mechanisms are, however, often insufficient, and RV dysfunction eventually occurs. After the recent Fifth World Symposium on Pulmonary Hypertension, a definition of failure of the right side of the heart secondary to PH was adopted: "Right heart failure in the setting of PH can be defined as a complex clinical syndrome due to a suboptimal delivery of blood or elevated systemic venous pressure at rest or exercise as a consequence of elevated RV afterload."2 The proposed definition takes into account both the systolic and diastolic characteristics of function of the right side of the heart, as well as physiological demands such as exercise.In underst...
