The bronchial circulation undergoes angiogenesis in several pathological conditions, such as lung neoplasm and bronchiectasis, but whether the pulmonary circulation can do this has been questioned. A woman treated with mitomycin C and 5-fluorouracil developed progressive, fatal pulmonary hypertension over 5 months. In addition to light and transmission electron microscopic examination of her lu...

Sinus venosus atrial septal defect (ASD) is usually associated with partial anomalous pulmonary venous return (PAPVR) of the right pulmonary veins to the superior vena cava (SVC), or to the SVC-right atrial junction. Standard procedure for repair of this defect is a patch roofing of the sinus venosus ASD and rerouting of pulmonary veins. However, the presence of SVC stenosis is a complication o...

Organic obstruction of the pulmonary veins is a rare cause of hypertension in the lesser circulation. Rhomberg in 1891 (quoted by Biirki (1963)) suggested that right ventricular hypertrophy might be due to disturbances in the pulmonary veins, but little note was taken of pulmonary vein lesions producing cor pulmonale until the 1930s when Hora (1934) and Mallory (1937) each described a single ca...

Recent studies suggest that pulmonary vein isolation can be an effective method of treatment for atrial fibrillation. This procedure can be performed with minimally invasive, totally endoscopic cardiac surgical techniques. We report our first successful endoscopic isolation of the pulmonary veins in a patient with paroxysmal atrial fibrillation. The procedure consisted of making a box lesion ar...

The anatomical abnormalities of the pulmonary veins may have a serious impact on complications that may arise during pulmonary lobectomy. We present a surgical case of left lung cancer in a patient, who was a 69-year-old male, with the left superior and inferior pulmonary veins forming a common trunk outside the pericardium. In this present case, because of extensive adhesions, incomplete lobul...

OBJECTIVE To determine the correlation between diastolic velocities on tissue Doppler imaging and age in a sample of healthy adults and to correlate age with the velocities of transmitral and pulmonary vein flows. METHODS Echocardiographic assessment of 51 healthy individuals, whose ages ranged from 21 to 69 years. The diastolic myocardial velocities were recorded on tissue Doppler imaging. T...

The present series describes a group of adults with left-to-right shunts including partial anomalous pulmonary venous return (PAPVR) and/or an atrial septal defect (ASD) evaluated with ECG-gated 128-slice multidetector computed tomography (MDCT). PAPVR is defined as a left-to-right shunt where one or more, but not all, pulmonary veins drain into a systemic vein or the right atrium. PAPVR involv...

We herein report a rare surgical case of the right middle lobe vein draining into the inferior pulmonary vein. The anatomical abnormalities in pulmonary veins can have a serious impact on complications during pulmonary surgery. Surgeons must be aware of any variation in the pulmonary vessels, and preoperative assessment of pulmonary venous anomalies is important during pulmonary surgery.

OBJECTIVE To evaluate the chronotropic response to exercise during immediate and late postoperative period after atrial fibrillation and mitral valve surgical treatment by different techniques. METHODS Prospective controlled clinical study of 42 patients presenting chronic AF associated mitral valve disease, who underwent surgery by the techniques of pulmonary veins isolation (n=16), Modified...
