Pulmonary hypertension is an increase in blood pressure in the pulmonary artery, pulmonary vein or pulmonary capillaries. Depending on the cause, pulmonary hypertension can be a severe disease with markedly decreased exercise tolerance and right-sided heart failure. Pulmonary hypertension can present as one of five different types: arterial, venous, hypoxic, thromboembolic, or miscellaneous. Chronic obstructive pulmonary disease with severe pulmonary hypertension is a rare disease. A 52-year-old man presented with a complaint of aggravating dyspnea. The mean pulmonary arterial pressure was 61.5 mmHg by Doppler echocardiogram. The patient was prescribed diuretics, digoxin, bronchodilator, sildenafil, bosentan and an oxygen supply. However, he ultimately died of cor pulmonale. Thus, diagnosis and early combination therapy are important.

Congenital coronary arterial fistulae are the most prevalent hemodynamically significant congenital coronary artery malformations. Definition of congenital coronary arterial fistula is a direct communication between a coronary artery and the lumen of one of the four cardiac chambers or coronary sinus or SVC, pulmonary artery or pulmonary vein close to the heart. It is often associated with additional congenital or acquired heart disease. A 49 year old male patient was admitted with the chief complaints of anginal pain and exertional dyspnea for 9 months. He was diagnosed as the right coronary arterial fistula combined with right coronary arteriosclerotic stenosis and old inferior myocardial infarction by cardiac evaluation. The right coronary arterial fistula was communicated between the just distal portion of acute marginal branch and coronary sinus. The operative procedure was as followings; after suture ligation of fistula opening in the coronary sinus under beating heart, coronary arterial bypass grafting with saphenous vein was performed at the just proximal portion of the posterior descending branch under cardiopulmonary bypass. The postoperative course was uneventful and he was discharged without anginal pain at the 8th postoperative day.

A technique applicated for physiologic correction of complex congenital cardiac disease suitable for Fontan procedure in which drainage of left superior vena cava and hepatocardiac vein to left atrium combined is described. We made one systemic venous baffle from left hepatocardiac vein to left superior vena cava and another systemic venous baffle from right inferior vena cava to the right superior vena cava with rigid prosthetic material[0.5mm thickness PTFE patch]. And then we anastomosed directly between the right sided atrial appendage and right pulmonary artery, and left-sided atrial wall beneath the appendage and left pulmonary artery. We believe that this procedure is superior to the method using intraatrial tube graft to divert the left hepatocardiac venous blood to right atrium, and applicable for physiologic correction of any complex congenital cardiac disease suitable for Fontan-type procedure in which anomalies of systemic venous drainage combined.

Lemierre syndrome is caused by acute oropharyngeal infections with secondary septic thrombophlebitis of the internal jugular vein and is characterized by frequent metastatic infections. A 56-year-old man presented with severe reddish inflammatory swelling of the right cervical soft tissue. Thrombophlebitis in the right internal jugular vein and multiple pulmonary embolisms were identified on neck and chest computed tomography (CT). He was treated with antibiotics and heparin for 4 weeks and then discharged without other complications.

Pulsed field ablation (PFA) was recently rediscovered as an emerging treatment modality for the ablation of cardiac arrhythmias. Ultra-short high voltage pulses are leading to irreversible electroporation of cardiac cells subsequently resulting in cell death. Current literature of PFA for pulmonary vein isolation (PVI) consistently reported excellent acute and long-term efficacy along with a very low adverse event rate. The undeniable benefit of the novel ablation technique is that cardiac cells are more susceptible to electrical fields whereas surrounding structures such as the pulmonary veins, the phrenic nerve or the esophagus are not, or if at all, minimally affected, which results in a favorable safety profile that is expected to be superior to the current standard of care without compromising efficacy. Nevertheless, the exact mechanisms of electroporation are not yet entirely understood on a cellular basis and pulsed electrical field protocols of different manufactures are not comparable among one another and require their own validation for each indication. Importantly, randomized controlled trials and comparative data to current standard of care modalities, such as radiofrequency- or cryoballoon ablation, are still missing. This review focuses on the "pearls" and "pitfalls" of PFA, a technology that has the potential to become the future leading energy source for PVI and beyond.

This is a report of a migrated polyethylene catheter from the arm vein cutdown site into the heart. The patient was a 48 years old male who was operated on for mitral stenosis complicated with pulmonary hypertension. On the 8th postoperative day after open mitral commissurotomy, polyethylene catheter embolization occurred. The catheter was removed successfully with an incision on the proximal basilic vein. The patient recovered uneventfully and discharged without complications.

Pulmonary sequestration is an unusual congenital malformation characterized by the presence of nonfunctioning lung tissue which usually has no communication with the normal bronchial tree and receives its blood supply from an anomalous systemic artery. Extralobar form is a very rare congenital malformation. We have experienced a 54 year old female patient with a mass in the upper lobe complaining of cough and blood tinged sputum. A triangular shaped mass was located in the left upper lobe, medially. The arterial blood supply were from the thoracic aorta and the pulmonary artery but there was no the tracheobronchial communication. The venous drainage was through the pulmonary vein. The mass was confirmed as extralobar pulmonary sequestration associated with a pericardial defect.

Pulmonary sequestration is an uncommon congenital malformation characterized by the presence of non-functioning lung tissues which receives its blood supply from an anomalous systemic artery instead of a pulmonary arterial branch. We present a case of intralobar pulmonary sequestration experienced lately. The patient was 7 years old girl with the complaints of chronic productive cough and right lower chest pain. Serial chest films showed a large cyst with or without a air-fluid level on the right lower lung field. Aortography revealed an aberrant artery originating from thoracic aorta just above the diaphragm and that drained into the right inferior pulmonary vein. During operation, a large abscess cavity measuring 6.5x5x5 cm in dimension at the right lower lobe was noted. And the two aberrant arteries, measuring 3 mm in diameter, arising from thoracic aorta 5 cm above the diaphragm was noted. After division and ligation of the aberrant arteries, right lower lobectomy was performed and the patient`s postoperative course was uneventful.

Two patients with uncorrectable cyanotic cardiac anomalies underwent total cavopulmonary shunt[modified Fontan operation]. Case I was a 14 years old male with dyspnea and cyanosis after birth. Aortogram showed TGA combined with overriding of aorta, pulmonary stenosis, complete atrioventricular septal defect, interruption of inferior vena cava, and situs inversus totalis. We had performed total cavopulmonary shunt using with 16 mm Gortex Graft in single atrium to bypass the hepatic vein to pulmonary artery. Postoperatively, patient sustained low PaCO2 and low cardiac output and then expired at 19th postoperative day. The cause of death of the patient would be low cardiac output. Case II was a 6 years old female with dyspnea and cyanosis after birth. Aortogram showed tricuspid atresia[Type IIb], transposition of great arteries, atrial septal defect, ventricular septal defect and pulmonary stenosis, We had performed total cavo-pulmonary shunt using intraatrial baffle[tunnel] with Goretex patch. The postoperative course of this patient was good without event.

Cor triatriatum is a rare entity of congenital heart disease characterized by the presence of a fibrousmuscular diaphragm that subdivides the left atrium into a proximal or "accessory" chamber and a distal or "true" left atrial chamber. In the other hand, cor triatriatum is a variant of abnormal connection between the pulmonary vein and true left atrium which is separated from accessory left atrium receiving pulmonary venous blood flow by fibromuscular diaphragm. We experienced two cases of cor triatriatum. One of them was classical, and the other case was combined with atrial septal defect and all pulmonary veins were drained into the " common pulmonary venous chamber " which connected with right atrium and there was no direct communication between the accessory chamber and true left atrium. The abnormal diaphragms were excised and the atrial septal defect was repaired with pericardial patch in case II. The postoperative courses were not eventful and the patients were discharged with good result, and have been in good condition upto now.n good condition upto now.
