Low-Risk Surgical Aortic Valve Replacement in the Era of Transcatheter Aortic Valve Implantation.

Open surgical aortic valve replacement (SAVR) is a viable alternative to transcatheter implantation in low-risk patients. In this light, we evaluated the safety and effectiveness of SAVR performed through conventional and less invasive surgical approaches in a high-volume center. We retrospectively reviewed the records of 395 consecutive patients who underwent open SAVR from January 2019 through December 2019 in our center. We evaluated and compared the operative results and postoperative major adverse outcomes of 3 surgical approaches: full median sternotomy (n=267), upper ministernotomy (ministernotomy) (n=106), and right anterior thoracotomy (minithoracotomy) (n=22). Overall, the 30-day all-cause mortality rate was 0.8% (3 patients). Stroke occurred in 8 patients (2%), disabling stroke in 4 patients (1%), myocardial infarction in 1 (0.2%), and surgical site infection in 13 (3.2%). There was no difference in 30-day mortality rate or incidence of postoperative major adverse events among the 3 surgical groups. Stroke and surgical site infection occurred more frequently, but not significantly so, in the full-sternotomy group. The mean hospital stay was longer after full sternotomy (9.1 ± 5.5 d) than after ministernotomy (7.5 ± 2.9 d) or minithoracotomy (7.4 ± 1.9 d) (P=0.012). Our findings suggest that open SAVR performed in a high-volume center is associated with a low early mortality rate and that less invasive approaches result in faster postoperative recovery and shorter hospital stays.

Unusual Presentation of Patent Ductus Arteriosus in Elderly Patient.

We presented a case of a 56-year-old man with giant pulmonary artery aneurysm caused by a misdiagnosed patent ductus arteriosus, severe multivalvular disease and active aortic valve endocarditis successfully treated by surgery. The correct diagnosis was missed despite preoperative diagnostics because the small patent ductus arteriosus was located at the distal part of common pulmonary trunk and a huge regurgitant signal overlapped its Doppler signal. Thorough evaluation of every patient, regardless of age, is necessary to recognize and treat this congenital anomaly.

Thorough evaluation of every patient, regardless of age, is necessary to recognize and treat this congenital anomaly.

Challenging surgery of giant right coronary aneurysm associated with coronary sinus fistula.

Coronary artery fistula is a rare congenital or acquired anomaly. It involves an abnormal connection between the coronary artery and the cardiac chambers or the large thoracic vessels. In some cases, the feeding coronary artery can become extremely dilated. The treatment includes a transcatheter or a surgical intervention depending on the complexity of the anomaly. We present the surgical treatment of the coronary artery to coronary sinus fistula, which includes the complete exclusion of the giant right coronary artery and followed by triple bypass surgery.

The role of ministernotomy in aortic valve surgery-A prospective randomized study.

BACKGROUND AND AIMS: The purpose of this prospective randomized study was to compare the early and midterm outcomes of aortic valve replacement (AVR) through upper ministernotomy with conventional AVR through median sternotomy. METHODS: One hundred patients undergoing elective AVR were randomized into two groups: the M group (upper ministernotomy group, n = 50) and the C group (conventional sternotomy group, n = 50). The operative data, major adverse outcomes, and postoperative variables were compared between the two groups of patients. A cross-sectional follow-up was performed 24.9 ± 5.8 months after surgery. RESULTS: The aortic cross-clamp time and cardiopulmonary bypass time were significantly longer in the M group. Similar incidences of major cardiac, neurologic and renal complications were recorded in both groups. Two patients (4%) in the C group developed wound infections. The length of ICU stay was similar in both groups. The patients in the M group had a shorter hospital stay compared with the patients in the C group (7.6 ± 2 days vs 9.3 ± 4.8 days; P = 0.022). Follow-up revealed that the time period needed to reach full recovery was significantly shorter in the ministernotomy group (1.7 ± 1.2 months vs 2.8 ± 1.6 months; P = 0.001). Morbidity and mortality data did not differ between the two groups. CONCLUSIONS: There was no difference in the major outcomes between the patients who underwent upper ministernotomy and those who underwent full sternotomy. The benefits of the minimally invasive approach were the shorter hospital stay and significantly faster recovery of patients after discharge from the hospital.

Cor triatriatum dexter and atrial septal defect in a 43-year-old woman.

Cor triatriatum dexter is a rare congenital heart anomaly in which a membrane divides the right atrium into 2 chambers. We report the case of a 43-year-old woman who had cor triatriatum dexter and a large atrial septal defect. During attempted percutaneous closure, the balloon disrupted the membrane and revealed that the defect had no inferior rim, precluding secure placement of an Amplatzer Septal Occluder. Surgical treatment subsequently proved to be successful. In patients with an incomplete membrane and a septal defect with well-defined rims, percutaneous treatment can be the first choice. In patients who have cor triatriatum dexter and unfavorable anatomic features or concomitant complex heart anomalies, open-heart surgery remains the gold standard for treatment.

The current role of surgery in treating adult patients with patent ductus arteriosus.

OBJECTIVE: Surgical closure of patent ductus arteriosus (PDA) is still required in selected adult patients. We analyzed the morphology of the anomaly and coexisting pathological findings in adult patients who were recently referred to our institute for surgical PDA repair. PATIENTS AND INTERVENTIONS: Six adult PDA patients who were not considered candidates for percutaneous closure underwent surgical PDA correction. In three patients with isolated PDA, computed tomographic scan revealed short, wide, and distorted ductus. In the remainder three patients, concomitant heart or aortic disease was found. Transpulmonary approach under total cardiopulmonary bypass or hypothermic circulatory arrest was performed. RESULTS: In all patients, a Dacron patch was used to close the duct. The balloon occlusion technique with normothermic cardiopulmonary bypass was performed in four patients. In one of these patients, the balloon occlusion was not feasible because of unfavorable ductal anatomy, and PDA was closed in short hypothermic circulatory arrest. In two patients with aortic aneurysm, PDA closure and aortic reconstruction were performed in deep hypothermic circulatory arrest. No significant complications occurred during postoperative course. After the mean follow-up period of 48 months, neither ductal reopening nor aneurysmal degeneration of remnant ductal tissue was found. CONCLUSION: Surgical PDA closure in adults remains the treatment of choice in wide, deformed PDAs unsuitable for percutaneous closure and PDAs associated with surgical aortic or heart disease.

Steroids and statins: an old and a new anti-inflammatory strategy compared.

OBJECTIVES: This study compared the anti-inflammatory effects of methylprednisolone (MP) and atorvastatin and analysed their influences on clinical variables in patients undergoing coronary revascularization. METHODS: Ninety patients with compromised left ventricular ejection fraction (≤30%) undergoing elective coronary surgery were equally randomized to one of three groups: statin group, treatment with atorvastatin (20 mg/day) 3 weeks before surgery; methylprednisolone group, a single shot of methylpredniosolone (10mg/kg); and control group. RESULTS: Postoperative IL-6 was higher in the control group when compared to the methylprednisolone and statin groups (p<0.01). IL-6 was higher in the statin-treated patients (p<0.05 versus methylprednisolone). Administration of methylprednisolone as well as statin treatment increased postoperative cardiac index, left ventricular stroke work index, decreased postoperative atrial fibrilation rate and reduced ICU stay (p<0.05 versus control). The number of patients requiring inotropic support was lower in the methylprednisolone group when compared with the other two groups (p<0.01). Tracheal intubation time was reduced in patients who received methylprednisolone (p<0.01 versus control). CONCLUSIONS: Preoperative administration of either methylprednisolone or atorvastatin reduced pro-inflammatory cytokine release, improved haemodynamics, decreased postoperative atrial fibrilation rate and reduced ICU stay in patients with significantly impaired cardiac function undergoing coronary revascularization. Treatment with methylprednisolone was associated with less inotropic support requirements and reduced mechanical ventilation time.

Radial artery harvesting for coronary artery bypass grafting: a stepwise-made decision.

BACKGROUND: The purpose of this study was to propose a safe, stepwise, testing system to select radial arteries that are suitable for conduits on the basis of their morphologies and characteristics of the collateral circulation. METHODS: Before operation, 113 patients underwent the modified Allen test, Doppler ultrasonography, and pulse oximetry testing. Morphologic criteria used for radial artery exclusion were small size of radial or ulnar artery (< 2 mm in inner diameter), diffuse calcifications, and congenital anomalies of forearm arteries. Collateral circulation was interpreted as insufficient if the reverse flow in the anatomic snuffbox was absent or if the increase of the ulnar peak systolic flow velocity was less than 20%. RESULTS: A positive modified Allen test was found in 10.6% of patients. As assessed by Doppler ultrasonography, 27 patients (23.9%) were not candidates for radial artery harvesting according to morphologic and functional abnormalities of forearm and hand circulation. Pulse oximetry test results were abnormal in 6.2%. After a follow-up period of 8.9 +/- 1.8 months, 23 patients (29.1% of operated patients) were controlled for Doppler ultrasonographic changes in the ulnar artery. The mean peak systolic flow velocity was significantly higher than the preoperative value measured at rest (p < 0 .001). CONCLUSIONS: After preoperative tests, including the modified Allen test, Doppler ultrasonography, and pulse oximetry, 30.1% of patients were not considered candidates for radial artery harvesting. This method provides preoperative radial artery selection according to its morphologies, compensatory capacity of collateral circulation, and anatomic properties of ulnar artery.

Musculocutaneous latissimus dorsi free transfer flap for total phalloplasty in children.

OBJECTIVE: Total phalloplasty is rarely performed in children due to the mutilation involved and the dilemma concerning neophallic size in children. We present a musculocutaneous latissimus dorsi free transfer flap for total phalloplasty in children with difficult psychological problems. MATERIALS AND METHODS: Total phalloplasty was performed in eight boys aged between 10 and 15 years. Indications were small penis after failed epispadias repair (4), micropenis (3) and intersexuality (1). A musculocutaneous latissimus dorsi free flap was harvested with thoracodorsal artery, vein and nerve. The flap was transferred to the pubic region and anastomosed to the femoral artery, saphenous vein and ilioinguinal nerve. Two-staged urethroplasty was performed in five patients using buccal mucosa, while in the remaining three a Mitrofanoff channel had been created previously. An inflatable penile prosthesis was implanted in two cases after puberty. RESULTS: Follow-up was from 6 to 53 months (mean: 29 months). Penile size varied from 13 to 16 cm in length and from 10 to 12 cm in circumference. No flap necrosis, either partial or total, was noted. The donor site healed acceptably in four cases while in the remaining four moderate scarring occurred. Function of the penile prostheses is satisfactory. Psychological status is significantly improved in all children. CONCLUSION: Phalloplasty in childhood is indicated to prevent profound psychological problems related to body dysmorphia. The musculocutaneous latissimus dorsi flap is a possible choice for phalloplasty in children that enables good neophallic size as in adults. We recommend this surgery to be performed before puberty to ensure optimal psychosexual pubertal development.
