Ça lış ma pla nı: Ekim 2006-Şubat 2012 tarihleri arasında dokuz hastaya (5 erkek, 4 kadın; ort. yaş 18.4±6.3 yıl; dağılım 8-27 yıl) enjekte edilebilen stent ile PKİ yapıldı. Tüm hastalarda ekokardiyografik olarak şiddetli pulmoner kapak yetmezliği, ilerlemiş sağ ventrikül dilatasyonu ve disfonksiyonu vardı. Hiçbir hastada rezidüel ventriküler septal defekt (VSD) görülmedi. Bul gu lar: Çalışmada bir hastaya 23 mm, iki hastaya 25 mm, iki hastaya 27 mm, üç hastaya 29 mm ve bir hastaya 31 mm kapak implante edildi. Ameliyat sonrası ekokardiyografik incelemede yedi hastada hiç kapak yetmezliğine rastlanmazken, iki hastada hafif derecede kapak yetmezliği saptandı. Ortalama pik sistolik gradyanı 12.6±3.7 mmHg ve ortalama sistolik gradyanı 8.3±2.4 mmHg olarak hesaplandı. Ortalama takip süresi 34±17 ay (dağılım, 1.5 ila 58 ay) idi. Hastaların hiçbirine tekrar ameliyat gerekmedi. So nuç:Atan kalpte PKİ'nin avantajları; kardiyopulmoner baypas olmaksızın uygulanabilmesi, büyük boyutlu kapakların kullanılabilirliği, herhangi bir girişim sınırlamasının olmaması ve kapağın yer değiştirmesini önleyecek şekilde kapağın pulmoner artere tespitine imkan vermesidir. Kapağın no-react özelliği, kapak dejenerasyon riskini de azaltmaktadır. Anah tar söz cük ler: Doğuştan kalp hastalığı; atan kalpte cerrahi; pulmoner kapak; Fallot tetrolojisi. Background:This study aims to assess the early-and midterm results of off-pump pulmonary valve implantation (PVI). Methods: Between October 2006 and February 2012, nine patients (5 males, 4 females; mean age 18.4±6.3 years; range 8 to 27 years) underwent off-pump PVI with an injectable stent. Echocardiography revealed severe pulmonary valve regurgitation, progressive right ventricular dilatation and dysfunction in all patients. No residual ventricular septal defect (VSD) was seen. Results: We implanted a 23 mm valve in one patient, a 25 mm valve in two patients, a 27 mm valve in two patients, a 29 mm valve in three patients and a 31 mm valve in one patient. Postoperative echocardiographic examination revealed no regurgitation in seven patients with mild valve regurgitation in two patients. The mean peak systolic gradient was 12.6±3.7 mmHg, while the mean systolic gradient was 8.3±2.4 mmHg. The mean follow-up was 34±17 months (range, 1.5 to 58 months). None of the patients needed reoperation. Conclusion:The advantages of off-pump PVI include the applicability without cardiopulmonary bypass, availability of large-sized valves, the absence of any interventional limitation and the opportunity for fixation into the pulmonary artery to avoid valve migration. No-react nature of the valve also minimizes the degeneration risk of the valve.

Fungal endocarditis is relatively unusual in children although it is one of the most feared forms of endocarditis. Candida species are the most common organisms recovered. In neonates, this infection may be a complication of intensive care measures, including hyperalimentation fluid infusion, use of broad-spectrum antibiotics for a prolonged time, and extended use of indwelling venous catheters. The mortality rate from fungal endocarditis is high, even with intensive medical and surgical therapy. The present paper aimed to present a third-month-old girl baby with candida infective endocarditis (fungus ball) diagnosed and surgically operated.

Research paper thumbnail of A rare case of non-traumatic acute intraabdominal hemorrhage: ruptured superior mesenteric artery aneurysm

The patient was hospitalized upon complaint of nonspecific severe abdominal pain. Diagnosis of SMAA was established by abdominal Doppler ultrasound that showed a pseudo-aneurysmal lesion with size of 76 × 47 mm at the superior mesenteric main branch. Endovascular stenting was not performed because of the wide neck in the segment of the jejunal branches from SMA and the risk of branch loss during treatment. On the second day of hospitalization, the patient developed an acute abdomen. At explorative laparotomy for intraabdominal bleeding, the root of superior mesenteric artery was immediately and temporarily clamped to provide bleeding control. Aneurysmal tissue was resected and affected part was repaired by Dacron prosthetic graft to maintain proximal and distal vascular continuum. Intestinal viability was preserved. The patient survive...

Research paper thumbnail of Interventions Involving the Use of Covered Coronary Artery Stents for Pseudoaneurysms of Blalock-Taussig Shunts

A pseudoaneurysm may rupture or may result in other adverse events including compression of mediastinal structures or collapse of the underlying lung parenchyma. Shunt-related pseudoaneurysm may be associated with shunt occlusion, bacteremia, or pulmonary hemorrhage. We describe two cases complicated by large pseudoaneurysm formation, following systemic-to-pulmonary artery shunt operations. The patients in question had recurrent pulmonary hemorrhage. Both underwent successful placement of covered coronary artery stents.

Between June 2005 and June 2013, 25 patients (15 male, 10 female) underwent cardiac hydatid cyst operation. The mean patient age was 33.4±12.6 (15-75) years. The most common presenting symptom was dyspnoea. Cysts were located only in the heart in 16 patients, lung in 4 patients, liver in 4 patients, and brain with lung involvement in 1 patient. Concomitant cardiac and pulmonary surgery was performed in 2 patients. The cardiac hydatid cysts were intracavitary in 11 patients and extracavitary in 14 patients. We used cardiopulmonary bypass in all but 1 patient, who presented with an extracavitary cyst. In 3 patients, surgery was performed with cardiopulmonary bypass without cross-clamping of the aorta. There were no mortalities in the early follow-up period. Cardiac echinococcosis is a rare but fatal disease and should be surgically treated when diagnosed. There is some controversy about how echinococcosis spreads to the heart (via haematogenous spread or direct extension from adjacent structures). According to our study, we think that haematogenous spread is the main method of the distribution of cardiac echinococcosis, and the direct extension method from adjacent structures must be questioned.

AVR with a Sorin Freedom Solo valve was performed in 14 patients between March 2006 and March 2011. Patients aged > or = 60 years (male:female ratio 6:8; mean age 73.28 +/- 5.42 years) who required AVR with the Sorin Freedom Solo valve according to the surgeon's choice were included in the study. The valvular prosthesis was implanted in the supra-annular position, using a single suture line. Eight patients underwent an isolated AVR; combined interventions were carried out in the other patients due to concomitant cardiac disease. One patient died during the immediate perioperative period, and two more during the follow up, from non-cardiac causes. The mean maximum transvalvular gradient of patients with aortic stenosis was 88.1 +/- 20.2 mmHg, and this fell to 26.4 +/- 7.6 mmHg during the early postoperative period. The mean gradient at one year of follow up was further decreased to 19.4 +/- 5.3 mmHg. The left ventricular end-diastolic and end-systolic diameters were also significantly reduced, from 4.8 +/- 0.9 to 4.3 +/- 0.6 cm and from 3.2 +/- 0.6 to 2.8 +/- 5.3 cm, respectively. The average left ventricular ejection fraction was 60.2 +/- 4.9% preoperatively, and 63.2 +/- 2.1% at one year after surgery (p = NS). No paravalvular leakage, endocarditis, prosthesis failure or neurologic events were reported among patients. The Sorin Freedom Solo stentless valve has provided good early and intermediate-term results. Implantation of the prosthesis is straightforward, with low rates of morbidity and mortality. However, these data require further support from larger patient series and long-term follow up.

Percutaneous closure of a patent ductus arteriosus (PDA) was first described by Porstmann in 1966. Since that time, different types of coils and occluder devices have been used, with varying results. Although the use of Cook detachable coils has produced satisfactory results in closure of small PDAs (<2 mm), an increased incidence of residual shunt, hemolysis, and embolization have been reported in closure of larger PDAs. The advantages when compared to surgical closure include shorter procedure time and hospital stay and no scar being left.

Drive line infection is a life-threating complication for the patient and a difficult problem for surgeons to resolve. In our patient, after LAVD implantation recurrent drive line infection episodes occurred and standard therapeutic strategies failed to cure the infection. Therefore, we performed an old, well-known omentoplasty plasty technique to heal the abscess. After omentoplasty and appropriate antibiotic therapy, the drive line infection healed uneventfully. The patient is still under control for 14 months without any signs of infection. Omentoplasty may be kept in mind for patients with resistant drive line infections.

We present our findings regarding transcatheter closures of PDA. The inclusion criteria were a weight of <6 kg and the presence of PDA symptoms. The study subjects were divided into two groups: <6 kg and premature infants. A total of 69 infants were included. The mean ages and weights of the <6 kg and the preterms were 5.4 ± 2.7 months and 30.3 ± 19.9 days, and 4.6 ± 0.8 and 1.7 ± 0.3 kg, respectively. Type C PDAs were most frequently observed in the premature group, and type A was in <6 kg. Sixteen of the patients were premature infants, and 81.2% of them had an extremely low birth weight. All of the premature infants had comorbidities, and had been receiving respiratory support therapy. Transcatheter closure was successfully completed in 81.2% of the premature infants and 94.3% of the <6-kg infants. Major complications occurred in 4 ...

The most prevalent malignant cardiac tumors are angiosarcomas. Autopsy specimens, microscopic slides, clinical and intraoperative data from a 72-year-old woman referred to our hospital with a suspected mediastinal tumor were studied. The patient was diagnosed with primary cardiac angiosarcoma by microscopic examination under surgery and underwent resection of the tumor, which compressed and obstructed the right atrium and ventricle. She was discharged from our hospital after 3 weeks and died of right heart failure 2 months after the operation.

In many cases, an aneurysm accompanies this defect. The aneurysm can have advantageous consequences on defect hemodynamics. However, it also has numerous complications that are frequently encountered in clinical practice. In this case, we describe a patient with a membranous VSD with giant aneurysm formation contributing to subpulmonic severe obstruction.

We herein present the case of a 3-year-old male who unintentionally injured himself by pricking his own chest with a sewing needle and introducing it through the left-lower margin of his sternum into his right ventricle. The needle was located anterior-posteriorly over the right ventricle. An anterior thoracotomy was performed, and the needle was safely removed. No hemorrhage or arrhythmia was seen, so the operation was ended. An early diagnosis and intervention proved to be life-saving for this penetrating cardiac injury.

To our knowl edge, only two reports of thyroid tissue on the aorta have been reported in the English literature. A 42-year old woman was found to have a right paracardiac mass. Sternotomy revealed a firm and encapsulated tumor attached to the anterolateral surface of the ascending aorta and a defect in the right superior part of the pericardium. The mass was completely excised and histopathologic examination confirmed a multinodular goiter. We discuss the features of this rare tumor.

Methods: Between January 2000 and December 2011, after 9972 sternotomies, postoperative mediastinitis was diagnosed in 90 patients. The treatment modalities divided the patients into two groups: group 1 patients (n = 47) were initially treated with the negative pressure wound therapy and group 2 patients (n = 43) were underwent conventional treatment protocols. The outcomes were investigated with Kaplan-Meier method, log-rank test, Student's test and Fisher's exact test. Results: The 90-days mortality was found significantly lower in the negative pressure wound group than in the conventionally treated group. Overall survival was significantly better in the negative pressure wound group than in the conventionally treated group. Conclusion: Negative pressure wound therapy is safe and reliable option in mediastinitis after cardiac surgery, with excellent survival and low failure rate when compared with conventional treatments.

Between June 2005 and June 2013, 25 patients (15 male, 10 female) underwent cardiac hydatid cyst operation. The mean patient age was 33.4±12.6 (15-75) years. The most common presenting symptom was dyspnoea. Cysts were located only in the heart in 16 patients, lung in 4 patients, liver in 4 patients, and brain with lung involvement in 1 patient. Concomitant cardiac and pulmonary surgery was performed in 2 patients. The cardiac hydatid cysts were intracavitary in 11 patients and extracavitary in 14 patients. We used cardiopulmonary bypass in all but 1 patient, who presented with an extracavitary cyst. In 3 patients, surgery was performed with cardiopulmonary bypass without cross-clamping of the aorta.

The valvular prosthesis was implanted in the supra-annular position, using a single suture line. Eight patients underwent an isolated AVR; combined interventions were carried out in the other patients due to concomitant cardiac disease. One patient died during the immediate perioperative period, and two more during the follow up, from non-cardiac causes. The mean maximum transvalvular gradient of patients with aortic stenosis was 88.1 +/- 20.2 mmHg, and this fell to 26.4 +/- 7.6 mmHg during the early postoperative period. The mean gradient at one year of follow up was further decreased to 19.4 +/- 5.3 mmHg. The left ventricular end-diastolic and end-systolic diameters were also significantly reduced, from 4.8 +/- 0.9 to 4.3 +/- 0.6 cm and from 3.2 +/- 0.6 to 2.8 +/- 5.3 cm, respectively. The average left ventricular ejection fraction was 60.2 +/- 4.9% preoperatively, and 63.2 +/- 2.1% at one year after surgery (p = NS). No paravalvular leakage, endocarditis, prosthesis failure or neurologic events were reported among patients. The Sorin Freedom Solo stentless valve has provided good early and intermediate-term results. Implantation of the prosthesis is straightforward, with low rates of morbidity and mortality. However, these data require further support from larger patient series and long-term follow up.

The study subjects were divided into two groups: <6 kg and premature infants. A total of 69 infants were included. The mean ages and weights of the <6 kg and the preterms were 5.4 ± 2.7 months and 30.3 ± 19.9 days, and 4.6 ± 0.8 and 1.7 ± 0.3 kg, respectively. Type C PDAs were most frequently observed in the premature group, and type A was in <6 kg. Sixteen of the patients were premature infants, and 81.2% of them had an extremely low birth weight. All of the premature infants had comorbidities, and had been receiving respiratory support therapy. Transcatheter closure was successfully completed in 81.2% of the premature infants and 94.3% of the <6-kg infants. Major complications occurred in 4 ...

The most prevalent malignant cardiac tumors are angiosarcomas. Autopsy specimens, microscopic slides, clinical and intraoperative data from a 72-year-old woman referred to our hospital with a suspected mediastinal tumor were studied. The patient was diagnosed with primary cardiac angiosarcoma by microscopic examination under surgery and underwent resection of the tumor, which compressed and obstructed the right atrium and ventricle. She was discharged from our hospital after 3 weeks and died of right heart failure 2 months after the operation.

AVR with a Sorin Freedom Solo valve was performed in 14 patients between March 2006 and March 2011. Patients aged > or = 60 years (male:female ratio 6:8; mean age 73.28 +/- 5.42 years) who required AVR with the Sorin Freedom Solo valve according to the surgeon's choice were included in the study. The valvular prosthesis was implanted in the supra-annular position, using a single suture line. Eight patients underwent an isolated AVR; combined interventions were carried out in the other patients due to concomitant cardiac disease. One patient died during the immediate perioperative period, and two more during the follow up, from non-cardiac causes. The mean maximum transvalvular gradient of patients with aortic stenosis was 88.1 +/- 20.2 mmHg, and this fell to 26.4 +/- 7.6 mmHg during the ...

In many cases, an aneurysm accompanies this defect. The aneurysm can have advantageous consequences on defect hemodynamics. However, it also has numerous complications that are frequently encountered in clinical practice. In this case, we describe a patient with a membranous VSD with giant aneurysm formation contributing to subpulmonic severe obstruction.

We herein present the case of a 3-year-old male who unintentionally injured himself by pricking his own chest with a sewing needle and introducing it through the left-lower margin of his sternum into his right ventricle. The needle was located anterior-posteriorly over the right ventricle. An anterior thoracotomy was performed, and the needle was safely removed. No hemorrhage or arrhythmia was seen, so the operation was ended. An early diagnosis and intervention proved to be life-saving for this penetrating cardiac injury.

To our knowl edge, only two reports of thyroid tissue on the aorta have been reported in the English literature. A 42-year old woman was found to have a right paracardiac mass. Sternotomy revealed a firm and encapsulated tumor attached to the anterolateral surface of the ascending aorta and a defect in the right superior part of the pericardium. The mass was completely excised and histopathologic examination confirmed a multinodular goiter. We discuss the features of this rare tumor.

Methods: Between January 2000 and December 2011, after 9972 sternotomies, postoperative mediastinitis was diagnosed in 90 patients. The treatment modalities divided the patients into two groups: group 1 patients (n = 47) were initially treated with the negative pressure wound therapy and group 2 patients (n = 43) were underwent conventional treatment protocols. The outcomes were investigated with Kaplan-Meier method, log-rank test, Student's test and Fisher's exact test. Results: The 90-days mortality was found significantly lower in the negative pressure wound group than in the conventionally treated group. Overall survival was significantly better in the negative pressure wound group than in the conventionally treated group. Conclusion: Negative pressure wound therapy is safe and reliable option in mediastinitis after cardiac surgery, with excellent survival and low failure rate when compared with conventional treatments.
