Disturbance of the pulmonary circulation is a factor in almost all cardiac and pulmonary diseases, yet despite considerable research into the underlying structure and function of the cardio-pulmonary system the subject continues to present considerable clinical difficulties to the practicing physician. This second edition has therefore been designed and written specifically with the busy clinician in mind, and will establish "Pulmonary Circulation" as the definitive reference in this important field. While retaining the theoretical and scientific content of the previous edition, this comprehensive update is more clinically directed. Highly structured throughout, early chapters are devoted to the structure, function and pathophysiology of the pulmonary circulation. Diagnostic methods key to the correct evaluation of pulmonary hypertension, including echocardiography, imaging techniques and cardiac catheterisation, are covered in detail. The book then moves on to a consideration of the different disorders of the pulmonary circulation, their diagnosis and their treatment, including arterial and venous hypertension, thromboembolism and vascular tumors. Other issues tackled include the pulmonary circulation in critical care, disorders causing intra-pulmonary shunt, and the pulmonary circulation in special environments such as high altitude, underwater and in the womb. The second edition also features an expanded pediatric section, and adherence to the new Evian classification of pulmonary hypertension. "Pulmonary Circulation" will remain in this second edition an invaluable reference for the pulmonary hypertension specialist, and should be found on the shelf of every cardiac, pulmonary and intensive care unit as an excellent resource for both clinicians and scientists.
